ちょっと前のニュースですがCXO Onlineの記事 https://cxotoday.com/press-release/digi-yatra-crosses-4-million-user-milestone/
Starting with just three airports, Delhi, Bengaluru, and Varanasi, Digi Yatra has expanded its footprint across major airports in the country, including Mumbai, Hyderabad, Pune and Kolkata. Currently operational at 14 airports, very soon  Digi Yatra plans to expand to an additional 15 airports.

3つの空港から始まって現在14の空港で利用でき、もうすぐ15番目の空港でも使えるようにする予定らしいです。

By adopting Digi Yatra, passengers have been able to cut down on airport entry time from 15-20 seconds to around 5 seconds.

これまで15-20秒かかっていた空港への入場が5秒で済むようになったとのこと。20秒ならいいじゃんって思ってしまいますが、インドくらいの人口のところだとものすごい効果なのかもしれません。

まぁ、日本でも顔認証ゲートは導入されているので、VCベースかどうかは置いておいて、この流れは世界へ広がっていくんでしょうね。

One interesting observation is the impact of environmental factors on training performance at scale. For Llama 3 405B , we noted a diurnal 1-2% throughput variation based on time-of-day. This fluctuation is the result of higher mid-day temperatures impacting GPU dynamic voltage and frequency scaling.

During training, tens of thousands of GPUs may increase or decrease power consumption at the same time, for example, due to all GPUs waiting for checkpointing or collective communications to finish, or the startup or shutdown of the entire training job. When this happens, it can result in instant fluctuations of power consumption across the data center on the order of tens of megawatts, stretching the limits of the power grid. This is an ongoing challenge for us as we scale training for future, even larger Llama models.

llm-gguf I just released a new alpha plugin for LLM which adds support for running models from Meta's new Llama 3.1 family that have been packaged as GGUF files - it should work for other GGUF chat models too.

I just released a new alpha plugin for LLM which adds support for running models from Meta's new Llama 3.1 family that have been packaged as GGUF files - it should work for other GGUF chat models too.

If you've already installed LLM the following set of commands should get you setup with Llama 3.1 8B:

llm install llm-gguf llm gguf download-model \ https://huggingface.co/lmstudio-community/Meta-Llama-3.1-8B-Instruct-GGUF/resolve/main/Meta-Llama-3.1-8B-Instruct-Q4_K_M.gguf \ --alias llama-3.1-8b-instruct --alias l31i

This will download a 4.92GB GGUF from lmstudio-community/Meta-Llama-3.1-8B-Instruct-GGUF on Hugging Face and save it (at least on macOS) to your ~/Library/Application Support/io.datasette.llm/gguf/models folder.

Once installed like that, you can run prompts through the model like so:

llm -m l31i "five great names for a pet lemur"

Or use the llm chat command to keep the model resident in memory and run an interactive chat session with it:

llm chat -m l31i

I decided to ship a new alpha plugin rather than update my existing llm-llama-cpp plugin because that older plugin has some design decisions baked in from the Llama 2 release which no longer make sense, and having a fresh plugin gave me a fresh slate to adopt the latest features from the excellent underlying llama-cpp-python library by Andrei Betlen.

As we've noted many times since March, these benchmarks aren't necessarily scientifically sound and don't convey the subjective experience of interacting with AI language models. [...] We've instead found that measuring the subjective experience of using a conversational AI model (through what might be called "vibemarking") on A/B leaderboards like Chatbot Arena is a better way to judge new LLMs.

[Anthony Robledo at USA Today]

"Tesla CEO Elon Musk said his estranged transgender daughter was "killed" by the "woke mind virus" after he was tricked into agreeing to gender-affirming care procedures."

The thing is, his daughter Vivian is perfectly happy with the decision. The thing that's causing Musk pain is not her decision to transition; it's that she's cut him off and no longer speaks to him. Interviews like this illustrate why.

That so many of his decisions are governed by this absolute loser energy says a lot. Just calm down, call your daughter, and reconcile.

As USA Today points out:

"Gender-affirming care is a valid, science-backed method of medicine that saves lives for people who require care while navigating their gender identity. Gender-affirming care can range from talk or hormone therapy to surgical intervention."

It's not done flippantly; a huge amount of care and attention is undertaken, particularly for minors. This backlash is pure conservative hokum: it does not have any scientific or factual basis. It just makes some small-minded, old-fashioned people feel uncomfortable.

Kimberley Trip, Day 20: Rottnest Island

Tuesday, June 11, 2024 We have heard a lot about Rottnest Island, which is just off the coast of Perth.

Tuesday, June 11, 2024

We have heard a lot about Rottnest Island, which is just off the coast of Perth. Rottnest (“Rotto” to the locals) is a recreational island with cabins for rent, several beaches with snorkeling (in the summer), restaurants, a golf course, skydiving, and more. It is also the home of about 10,000 quokkas. Quokkas are small marsupials billed as “the happiest animals on earth.”

We booked a round trip on the Rottnest Express last night, so we got an early start this morning and grabbed coffee and a breakfast wrap on the way to the pier. We got seats upstairs for both the view and the airflow. The trip started slow (about 10 knots) as we left the pier, increased to about twice that once we reached a broad section of the Swan River, and slowed again as we approached Fremantle. We stopped, picked up more passengers there, and then proceeded to Rottnest Island at a higher speed.

Although we had been equipped with a map, we weren’t sure where to go when we got to Rottnest. We stumbled on the main village and were heading out when we noticed some rain starting to fall. We returned to the village to get some snacks, and the sky opened up: it poured! We were thankful to be in the village as there weren’t a lot of other places to get out of the rain. While there, we noticed our first quokka and gates on the grocery entrance and other businesses designed to keep quokkas out.

Despite a lot of public education not to feed the quokkas, many of them hang out in the village to eat up the crumbs and other droppage from human diners. They are indeed cute, but the “always smiling” thing seemed a little overstated. They can be a little aggressive, too: when Kenna and I shared a chicken sandwich for lunch, a quokka climbed on the bench between us and tried to get to the sandwich. We moved rather quickly.

Osprey Nest at Cape Vlamingh, Rottnest Island

The rain continued off and on, limiting our ability to venture beyond the village until we boarded a bus for a “discovery” tour we had booked for the afternoon. The tour took us around the perimeter of the island, with excellent descriptive commentary from a guide on the bus. We stopped at several points to take pictures, most notably at the far west end facing the vast Indian Ocean, where there was also a large osprey nest.

Following our tour, we stopped briefly to pick up souvenirs (a t-shirt for me), and it was time for our return trip to Perth. Along the way, in one of the slower-speed segments, a couple of hydrofoil surfers managed to “draft” off our ship, keeping up for quite a long time. We were also tailed briefly by a few dolphins.

Returning to our hotel, we were exhausted but managed to venture out for a quick pizza dinner.

Introducing Llama 3.1: Our most capable models to date

We've been waiting for the largest release of the Llama 3 model for a few months, and now we're getting a whole new model family instead.

Meta are calling Llama 3.1 405B "the first frontier-level open source AI model" and it really is benchmarking in that GPT-4+ class, competitive with both GPT-4o and Claude 3.5 Sonnet.

I'm equally excited by the new 8B and 70B 3.1 models - both of which now support a 128,000 token context and benchmark significantly higher than their Llama 3 equivalents. Same-sized models getting more powerful and capable a very reassuring trend. I expect the 8B model (or variants of it) to run comfortably on an array of consumer hardware, and I've run a 70B model on a 64GB M2 in the past.

The 405B model can at least be run on a single server-class node:

To support large-scale production inference for a model at the scale of the 405B, we quantized our models from 16-bit (BF16) to 8-bit (FP8) numerics, effectively lowering the compute requirements needed and allowing the model to run within a single server node.

Meta also made a significant change to the license:

We’ve also updated our license to allow developers to use the outputs from Llama models — including 405B — to improve other models for the first time.

We’re excited about how this will enable new advancements in the field through synthetic data generation and model distillation workflows, capabilities that have never been achieved at this scale in open source.

I'm really pleased to see this. Using models to help improve other models has been a crucial technique in LLM research for over a year now, especially for fine-tuned community models release on Hugging Face. Researchers have mostly been ignoring this restriction, so it's reassuring to see the uncertainty around that finally cleared up.

Lots more details about the new models in the paper The Llama 3 Herd of Models including this somewhat opaque note about the 15 million token training data:

Our final data mix contains roughly 50% of tokens corresponding to general knowledge, 25% of mathematical and reasoning tokens, 17% code tokens, and 8% multilingual tokens.

Update: I got the Llama 3.1 8B Instruct model working with my LLM tool via a new plugin, llm-gguf.

The biggest-ever global outage: lessons for software engineers

Cybersecurity vendor CrowdStrike shipped a routine rule definition change to all customers, and chaos followed as 8.5M machines crashed, worldwide. There are plenty of learnings for developers.

👋 Hi, this is Gergely with the monthly, free issue of the Pragmatic Engineer Newsletter. In every issue, I cover challenges at Big Tech and startups through the lens of engineering managers and senior engineers. To get issues like this in your inbox, sign up here:

Unless you were under a rock since last week, you likely heard about the CrowdStrike / Windows outage that took down critical services like airlines, banks, supermarkets, police departments, hospitals, TV channels, and more, around the world. Businesses saw their Windows machines crash with the “Blue Screen of Death,” and no obvious fixes – at least not initially. The incident was unusual in size and scale, and also because it involved software running at the kernel-level; a factor which gives this us all the more reason to take a look at it.

Today, we cover:

Recap. 8.5M Windows machines impacted across industries

Root cause. An update to naming rules for finding malicious processes somehow resulted in the CSAgent.sys process attempting to write to an invalid memory address, thus crashing the operating system

A very slow, manual fix. Four days after the outage, recovery was ongoing, as every single impacted machine and host had to be fixed manually

Who’s responsible? Obviously, CrowdStrike is and it’s tempting to think Microsoft should share blame. A regulation from 2009 could also have played a role

Learnings for software engineers. Quantify potential impact, do canarying/staged rollouts, treat configuration like code, and more

Note: this is the last issue before The Pragmatic Engineer goes on summer break. There will be no The Pulse on Thursday, and no new issues next week. We return on Tuesday, 6 August. Thanks for your continuing support of this publication!

1. Recap

Last Friday (19 July,) the largest-ever software-initiated global outage hit machines worldwide. Millions of Windows 10 and 11 operating systems used by societally-critical businesses like airlines, banks, supermarkets, police departments, hospitals, TV channels, etc, suddenly crashed with the dreaded “Blue Screen of Death,” and no obvious way to fix them. This was a truly global outage; the US, Europe, Asia, and Australia, were all hit. 

Global air travel descended into chaos, and in Alaska the emergency services number stopped working. In the UK, Sky News TV was unable to broadcast, and McDonalds had to close some of its Japanese outlets due to cash registers going down. In total, tens of thousands of businesses and millions of people were impacted. Meanwhile, in the world of Formula One racing, the Mercedes team saw its computers crash at the Hungarian grand prix. Ironically, one of the team’s sponsors is… CrowdStrike. Some photos of the outage in the wild:

All the business victims of this mega crash were customers of cybersecurity company CrowdStrike, which is the market leader in “endpoint security,” with around 20% market share. It installs software on Windows / Linux / Mac machines, and runs antivirus, firewalls, intrusion detection and prevention systems (IDP,) among others. What unleashed the global carnage was a single update by Crowdstrike to its ‘Falcon’ product.

We know 8.5M Windows machines were impacted globally from Microsoft sharing this number, later confirmed by CrowdStrike. Worst-hit of all might be Delta airlines, where around a third of flights (5,000) were canceled in three days. Even on day 4, Delta had to cancel another 1,000 flights as it recovered, and is on the hook for cash refunds for impacted customers.

2. Root cause

A few hours after Windows machines running CrowdStrike’s software started crashed, the company issued an update:

“CrowdStrike is actively assisting customers affected by a defect in a recent content update for Windows hosts. Mac and Linux hosts were not impacted. The issue has been identified and isolated, and a fix has been deployed. This was not a cyberattack.”

What happened is the company pushed out a “content” file (a binary file) to all customers at once, which then crashed the operating system. But how did it happen? As the incident was ongoing, some devs attempted to reconstruct what happened. Here are details from Patrick Wardle:

1. The process that crashed Windows is called “CSAgent.sys” 

2. The instruction that crashed is the Assembly instruction “mov  r9d, [r8].” This instructs to move the bytes in the r8 address to the r9d one. The problem is that r8 is an unmapped address (invalid), and so the process crashes!

The culprit: assembly instructions that crashed Windows machines across the globe. Source: Patrick Wardle on X

3. The crash was caused by the CSAgent.sys process reading a new “content” file CrowdStrike pushed to all clients called “C-00000291-*.sys” (where * can have additional characters.) Something went wrong related to this file and the parsing of it.

A day later, CrowdStrike shared more details:

1. The goal of the update was to detect maliciously-named pipes. CrowdStrike’s Falcon product observes how processes communicate on a machine, or across the network, to try and pinpoint malicious activity. The update was adding a new rule file to filter for suspiciously named pipes. A named pipe in the Windows world is a “named, one-way or duplex pipe for communication between the pipe server and one or more pipe clients.” These pipes can be used for inter-process communication (two processes talking to each other; here’s an example of processes sensing files between one another, or to communicate over the network. Named pipes are a common concept with operating systems for interprocess communication: Unix also uses this concept.

2. Released a new configuration file with new rules/naming. CrowdStrike calls config files that define behavior rules, like names for suspicious names pipes, “Channel files.” They store all these channel files in the location C:\Windows\System32\drivers\CrowdStrike\. These are numbered files, and the rules for named pipes are under number 291. Therefore, every file with the naming pattern “C-00000291-*.sys” is a rule for this category.

CrowdStrike released a new naming file in the update.

3. An unhandled error crashed the process and the operating system. While I’m itching to know about what the error actually was, CrowdStrike has only shared a very brief summary:

“The configuration update triggered a logic error that resulted in an operating system crash. This is not related to null bytes contained within Channel File 291 or any other Channel File.”

So, somehow, parsing these new naming rules resulted in an Assembly-level instruction that tries to move a memory location to an invalid location. This is what made Windows devices crash everywhere.

3. A slow, manual fix

Mitigating this outage was a lot more complicated than usual because a simple revert was insufficient. IT staff had to physically access each individual machine:

CrowdStrike posted mitigation steps for IT admins and developers wanting to get themselves unblocked, a few hours after the incident. The steps were:

Boot Windows into Safe Mode or the Windows Recovery Environment

Navigate to the C:\Windows\System32\drivers\CrowdStrike directory

Locate the file matching “C-00000291*.sys” and delete it

Boot the host

The recovery process might need a local administrator on a machine with the right to delete the offending file. The steps are specialized enough that regular users would struggle to perform the recovery: and so at most companies it’s up to IT staff to manually fix every machine. Plus, at many places all Windows laptops were impacted. An IT admin shared a glimpse of the task, posting an image of 120 of 2,000 laptops to be fixed in one weekend, ideally!

Some laptops to be reset. Source: Dunken K Bliths on X

As software engineers, when we see a highly manual process our first thought is whether we can automate it, or do it faster in a clever way. With 8.5M machines needing resets, it’s obvious a manual process is incredibly time consuming. So independent developers, and also Microsoft, stepped in:

iOS developer and Windows tinkerer Adam Demasi created the Unistrike tool a day later. With some additional setup, you can create a USB stick to plug into each impacted machine for faster recovery

Microsoft also released a similar recovery tool the day after the outage

Two days later, CrowdStrike shared that they were testing a new, faster recovery technique for customers

Four days after the outage, most of the 8.5M impacted Windows devices weren’t fixed. It turns out that crashing operating systems at scale is a lot harder to recover at scale than applications, for which patches can be sent out to clients (mobile and desktop apps,) or when the fix can be done server side (services, backend applications, web apps.)

4. Who’s responsible?

It was a little amusing that the news initially reported this as a “Microsoft outage” or a “Windows outage” because it’s a bit distant from the facts. So who “owns” the world’s biggest-ever software crash?

CrowdStrike – obviously

Needless to say, most blame lies with CrowdStrike. We can only speculate at this point about which areas were skipped, or done insufficiently thoroughly. Hopefully, we will learn more in a public-facing postmortem. Meantime, here are some questions that CrowdStrike should be asking – and, most likely, is:

1. Was the change tested, and how? Was the change in this config file (C-00000291-*.sys) tested in manual and automated scenarios? If so, how did the tests pass, and why did the crash happen in production? A more interesting question that only CrowdStrike can answer is how the configs were tested in an automated way; and indeed, were they? We know testing environments can never replicate production in full, so it’s expected that bugs can make their way through tests, undetected.

2. Were these config changes dogfooded? Was this change rolled out to CrowdStrike staff, before release to the public? If yes, did some CrowdStrike employees also see their OSs crash? If yes, then why did the rollout proceed? If there was dogfooding, but no employees’ machines crashed; an interesting question is: why not?

3. Was there a canary rollout? We cover the topic of canarying in Shipping to Production:

“Canarying” comes from the phrase “canary in the coal mine.” In the early 20th century, miners took caged canary birds with them underground. The bird has a lower tolerance for toxic gasses than humans do, so if the bird stopped chirping or fainted, it was a warning sign to miners that gas was present, and for them to evacuate.

Today, canary testing means rolling out code changes to a smaller percentage of the user base, then monitoring the health signals of this deployment for signs that something’s not right. A common way to implement canarying is to either route traffic to the new version of the code using a load balancer, or to deploy a new version of the code to a single node.”

Canarying is a subset of staged rollouts:

“Staged rollouts mean shipping changes step by step, evaluating the results at each stage before proceeding. Staged rollouts typically define the percentage of the user base to get the changed functionality, or the region where this functionality should roll out, or both.

A staged rollout plan may look like this:

Phase 1: 10% rollout in New Zealand (a small market to validate changes)

Phase 2: 50% rollout in New Zealand

Phase 3: 100% rollout in New Zealand

Phase 4: 10% rollout, globally

Phase 5: 25% rollout, globally

Phase 6: 50% rollout, globally

Phase 7: 100% rollout, globally

Between each rollout stage, a criteria is set for when the rollout can continue. This is typically defined as there being no unexpected regressions and the expected changes to business metrics being observed.”

Did CrowdStrike use these approaches, or was it more of a “YOLO rollout,” where the configuration file was pushed to all customers at the same time? Right now, we don’t know.

From the incident response communication, it sounds like the change was more a “YOLO rollout” because the changed file was labeled as “content,” not business logic. This is despite it containing rules on how to detect named pipes, which you could argue is business logic that should be rolled out in phases, not all at once!

4. Does CrowdStrike assume that binary (“content”) files cannot break software running at kernel level? Common rollout strategies for shipping code were likely absent when shipping these new configuration files. Did CrowdStrike assume – implicitly or explicitly – that these “content” files could not crash the process?

CrowdStrike’s software operates at the kernel level in Windows, meaning its process is operating with the highest level of privileges and access in the OS. This means it can crash the whole system; for example, by corrupting part of the OS’s memory. CrowdStrike operating at this level is necessary for it to oversee processes running across the OS, and to discover threats and vulnerabilities. But this also means that an update – even an innocent-looking content file! – can cause a crash. 

5. Did the company ignore a previous similar outage? A Hacker News commenter working at a civic tech lab shared that, a few months ago, CrowdStrike caused a similar outage for their Linux systems. This dev summarized:

“Crowdstrike did this to our production linux fleet back on April 19th [2024], and I've been dying to rant about it.

The short version is we're a civic tech lab, so have a bunch of different production websites made at different times on different infrastructure. We run Crowdstrike provided by our enterprise. Crowdstrike pushed an update on a Friday evening that was incompatible with the up-to-date Debian stable. So we patched Debian as usual, everything was fine for a week, and then all of our servers across multiple websites and cloud hosts simultaneously hard crashed and refused to boot.

When we connected one of the disks to a new machine and checked the logs, Crowdstrike looked like a culprit, so we manually deleted it, the machine booted, tried reinstalling it and the machine immediately crashed again. OK, let's file a support ticket and get an engineer on the line.

Crowdstrike took a day to respond, and then asked for a bunch more proof (beyond the above) that it was their fault. They acknowledged the bug a day later, and weeks later had a root cause analysis that they didn't cover our scenario (Debian stable running version n-1, I think, which is a supported configuration) in their test matrix. In our own post mortem there was no real ability to prevent the same thing from happening again: "we push software to your machines any time we want, whether or not it's urgent, without testing it," seems to be core to the model.”

These details suggest that CrowdStrike could or should have been aware that it can – and does – crash kernel processes with updates. If so, the obvious question is why this outage did not serve as a warning to tweak the rollout process, as opposed to just improving testing? 

In fairness, a company like CrowdStrike has hundreds of engineering teams, and one team observing an outage is information that will not necessarily spread through the organization. Still, the CrowdStrike process crashing the OS was surely a known vulnerability, as it’s the most obvious way to brick a customer’s machine which it is meant to defend.

Microsoft / Windows?

Why can CrowdStrike run processes at kernel level which can crash an operating system? After all, Apple made changes to MacOS to run third-party software at user level, not kernel. From Electric Light, in 2021:

“For some years now, Apple has been encouraging third-party developers to move away from kernel extensions to equivalents which run at a user level rather than in Ring 1. However, it has only been in the last year or so that Apple has provided sufficient support for this to be feasible. Coupled with the fact that M1 Macs have to be run at a reduced level of security to be able to load third-party kernel extensions, almost all software and hardware which used to rely on kernel extensions should now be switching to Apple’s new alternatives such as system extensions. This article explains the differences these make to the user.”

So on Mac, the same CrowdStrike process would run in the user space, and if it crashes it would not take the whole system down with it.

However, on Windows and Linux, antivirus and other cybersecurity software usually runs at the kernel level, and always has done. So why hasn’t Microsoft followed Apple’s approach and banned third parties from the kernel space? Turns out that a Symantec complaint in the 2000s, and EU regulation, played a role. 

Regulation to blame?

The Wall Street Journal asked Microsoft why it won’t limit third-party software like CrowdStrike to run only in the user space, not the kernel space. Its response:

“A Microsoft spokesman said it cannot legally wall off its operating system in the same way Apple does because of an understanding it reached with the European Commission following a complaint. In 2009, Microsoft agreed it would give makers of security software the same level of access to Windows that Microsoft gets.”

Ironically, all of this started in 2006 with Microsoft wanting to make its kernel more secure for Windows Vista. From CIO.com at the time (emphasis mine):

“Security vendors like Symantec are in a state of heightened sensitivity these days as they’ve begun to compete with Microsoft head-on, and the specter of further antitrust actions looms over Microsoft’s every move in the security space. Last week, the European Union’s spokesman on competition, Jonathan Todd, warned that the market could be threatened if Microsoft doesn’t allow security vendors a fair chance of competing.

Symantec and other security vendors dislike PatchGuard because it prevents them from accessing the Windows kernel. They say it will stop them from delivering important features like Symantec’s “anti-tampering” technology, which prevents malicious programs from modifying Symantec’s own software.

PatchGuard will also make it more difficult for security vendors to protect against malicious software that takes advantage of kernel-level bugs, said Eric Sites, vice president of research and development with Sunbelt Software. (...)

Microsoft declined to be interviewed for this article, but in an interview with IDG News last week a Microsoft executive said that PatchGuard was simply an effort to prevent the kernel from being misused.

“We think that there’s a significant amount of confusion around… certain security features in the product that we think raise the foundation,” said Stephen Toulouse, a senior product manager in the Security Technology Unit. “What we’re doing is we’re walling off the kernel from attackers, because the functionality that is currently there was never meant to be used by anybody — by software vendors or attackers.”

In the end, Symantec and other vendors won. Microsoft could only “ban” security vendors from running in the kernel space if it also did not run its own security software there. So while Microsoft could be seen as partly responsible for this crash, the company had little choice in the actions which created the circumstances for it to happen! 

There would have likely been a way, though: if Microsoft moved their own security solution – such as Windows Defender – out of the kernel space, closing it off to all security vendors, including itself. Doing so would likely mean a large enough re-architecture of the Windows security stack. It would also limit the capabilities of third-party vendor solutions, and any such change would trigger outcry and more complaints to regulators by security vendors. It would be no different to the complaints and escalations of 2006, when Vista attempted to lock vendors out of the kernel space.

5. Learnings for software engineers

Here are some learnings that us software engineers can take from this incident, as things stand:

Quantify the impact of software crashing everywhere

What happens if your company’s product crashes irrecoverably for a couple of hours? Ignore the fact that this seems so unlikely as to be impossible – because it has just happened to CrowdStrike. If it happened, what would the impact be on your company and the outside world? For example:

If Amazon crashed worldwide for a few hours, sellers would lose revenue and a subset of shoppers could lose access to essential items. Amazon would lose revenue and suffer reputational damage.

If TikTok crashed for hours worldwide for a few hours, brands would not be able to serve ads, and customers would feel indifferent, slightly annoyed, or furious about not being able to use the social platform. Far-fetched theories could emerge about TikTok being blocked, the company would lose ad revenue, and users would temporarily flock to alternatives like Instagram Reels and Snap.

If a major phone and internet carrier crashed, the impact would be far worse than the two above, combined. Businesses would struggle to operate and emergency services could be impacted. The damage would be reputational, lasting, and government intervention could also follow. Last November, we covered what happened when Half of Australia’s internet was cut off for 14 hours

This exercise is helpful because it can give a sense of how expensive an outage could be. Knowing the “blast radius” can help get buy-in to make systems more resilient, and make it quicker to detect and mitigate incidents.

Review how things reach production

What needs to happen for a code or asset change to be shipped to all customers? We go deep on this topic in Shipping to Production. As a recap, here are two extremes in shipping to production: CrowdStrike seems to have chosen the “YOLO” option for this change, and it cost them dearly:

Two “extremes” of shipping to production: YOLO and thorough verification. Source: Shipping to Production Do canarying / staged rollouts

If your software crashing everywhere has a big enough “blast radius” to make a failure unacceptable, then do not roll out changes to all customers at once! Do a canary or a staged rollout.

It’s true that canarying and staged rollouts are overkill for certain products, like those with few users, or which do not generate revenue, or are experimental. Setting up canarying or staged rollouts is effort and does slow down rollout. But if your product is used by many people, or is critical enough, then this rollout strategy is non-negotiable. Take it from former Google Chrome engineer Marc-Antoine Ruel:

“From the get go, Google Chrome had 3 release channels plus nightly builds:

canary (nightly), dev, beta, stable. Each increases the blast radius.

Dev did get broken builds. Beta broke in subtle ways. This release scheme reduced the blast radius.

Net result: 126 stable releases!”

Treat configuration like code

Staff engineer Jacques Bernier formerly worked at Twitch and has shared how Amazon treated code changes:

“The Amazon build and deploy system is one that I miss deeply. It was so powerful. And it considered all changes equal. It included code, dependencies all the way down to the operating system and infrastructure in the same build and deploy pipeline with multiple stages.

Config change is code. Infrastructure change is code change. Dependency update is code change. Code change is code change. It is all the same.

Staged rollout is one of the best ways (if not the best) to reduce blast radius.”

What changes do dependencies/vendors “silently” push?

CrowdStrike broke most customers’ businesses because it silently and automatically shipped business logic changes. Even if customers wanted to “block” a change, or only allow it for a subset of machines at first, they could not.

It’s a good reminder that software can be broken not just by code, but by your dependencies or vendors. So now is a good time to consider these questions:

How are dependencies (libraries, frameworks) updated? Are they done automatically, or manually? This is especially relevant when working with package managers that might get these automatically.

What about vendor dependencies – SDKs or APIs? Are you the one making changes, or are vendors pushing silent changes?

List all the points which could be affected by a faulty “silent” change from a third-party you use and (currently) trust.

An outage is no one person’s fault

It’s easy to blame whoever wrote an offending piece of code for a crash; perhaps an intern lacking experience, or a veteran engineer having a bad day. But pointing the finger of blame at individuals is the wrong approach. Microsoft Veteran Scott Hanselman summarizes why a failure at this scale is never one person’s fault (emphasis mine:)

“Here’s the thing folks. I’ve been coding for 32 years. When something like this happens it’s an organizational failure. Yes, some human wrote a bad line. Someone can “git blame” and point to a human, and it’s awful. 

But it’s the testing, the Cl/CD, the A/B testing, the metered rollouts, an “oh s**t” button to roll it back, the code coverage, the static analysis tools, the code reviews, the organizational health, and on and on. 

It’s always one line of code but it’s NEVER one person. Implying inclusion policies caused a bug is simplistic, reductive, and racist. Engineering is a team sport. Inclusion makes for good teams. Good engineering practices make for good software. Engineering practices failed to find a bug multiple times, regardless of the seniority of the human who checked that code in. 

Solving the larger system thinking SDLC matters more than the null pointer check. This isn’t a “git gud C++ is hard” issue and it damn well isn’t an DEI one.”

Takeaways

Widespread outages are always bad, but one upside is that they force us engineers to pause and reflect:

Can something similarly catastrophic happen at my company, and if so, how?

What would the impact be in my situation?

What do we do to avoid being the “next CrowdStrike?”

There’s no better time than now to make a case to your leadership for investing properly in reliability. The CrowdStrike outage is now officially the largest-ever software outage on the planet, and customers have suffered heavy financial and reputational damage. The financial loss is still unclear for CrowdStrike, but you can assume it will be huge, as some businesses will seek compensation for the damage done.

For CrowdStrike, the reputational damage could hardly be worse. Until a few days ago, the company was the gold standard in endpoint security compliance. No longer: its name is linked with the biggest outage anybody’s seen. After such a high-profile blunder that reveals the company had no staged rollout processes in place for business rule changes (“channel files,”) the reputation of Crowdstrike has suffered a hit which it will take a long time to recover from.

No business wants such a blow from a single bad deploy, but it’s happened. If you see gaps in your company’s release processes – testing, rollout, monitoring, alerting, etc – then now is the time to take your concerns and suggestions to the table! Talk with your manager or skip-level; they will be more likely to champion ideas which make production systems resilient.

CrowdStrike is certain to learn its lesson, and doubtless its future release processes will be world class. Good luck to the team there (and teams at all affected customers) for mitigating the outage, and for work ahead at CrowdStrike to overhaul internal processes.

Let’s hope many companies follow suit, so this historic event ends up being a net positive learning experience for the tech industry.

We’ve previously covered outages with interesting learnings. Check out these for more analysis and learnings, and for making systems more reliable:

今回はクレデンシャルのタイプごとに採用される選択的開示の手法の違いがあるかどうか、という話です。
リサーチの方法が結構面白くて、2007年から2022年までに発表されたタイプ別の選択的開示の方式、ゼロ知識証明の利用有無、ブロックチェーンの利用有無をまとめて傾向分析をしています。 分析結果から「2020年までは選択的開示署名ベース、ハッシュ値ベースの方式を採用したAC(Anonymous Credential)とABC(Attribute Based Credential)が中心だったのが、2020年以降はVC(Verifiable Credential)とZKP(ゼロ知識証明)を組み合わせた方法に焦点が当たってきている」と結論づけられています。もちろんリサーチベースの傾向なので実装とは別だとは思いますが、いよいよVC+ZKPが技術的にも確立されてきている、ということなのかもしれません。

"The Apache Software Foundation is making changes in an attempt to right a wrong it unintentionally created when it adopted its name 25-years ago."

This is an unnecessarily awkward article (why describe the existing logo as cool in this context?!) to describe a simple premise: the Apache Software Foundation is slowly, finally, moving away from its appropriation of the Apache name and its racist use of faux Native American imagery.

For a while, it's preferred to refer to itself as ASF, and now it's going to have a much-needed logo change. That's fine, but it needs to go much further. It's past time to just rip off the Band Aid.

Still, this is far better than the obstinate response we've seen in the past to requests for change. A new logo, slight as it is, is hopefully an iteration in the right direction.

Breaking Instruction Hierarchy in OpenAI's gpt-4o-mini

Johann Rehberger digs further into GPT-4o's "instruction hierarchy" protection and finds that it has little impact at all on common prompt injection approaches.

I spent some time this weekend to get a better intuition about gpt-4o-mini model and instruction hierarchy, and the conclusion is that system instructions are still not a security boundary.

From a security engineering perspective nothing has changed: Do not depend on system instructions alone to secure a system, protect data or control automatic invocation of sensitive tools.

"After much back and forth, Google has decided to keep third-party cookies in its Chrome browser. Turns out all the fuss over the years wasn’t in vain after all; the ad industry’s cries have finally been heard."

Advertisers are rejoicing. In other words: this is bad.

It's possible that Chrome's "new experience" that lets users make an "informed choice" across their web browsing is really good. Sincerely, though, I doubt it. Moving this to the realm of power user preferences rather than a blanket policy for everyone means that very few people are likely to use it.

The result is going to be a continued trend of tracking users across the web. The people who really, really care will do the work to use the interface; everyone else (including people who care about privacy!) won't have the time.

All this to help save the advertising industry. Which, forgive me, doesn't feel like an important goal to me.

Case in point: Chrome's Privacy Sandbox isn't actually going away, and this is what Digiday has to say about it:

"This could be a blessing in disguise, especially if Google’s plan gets Chrome users to opt out of third-party cookies. Since it’s all about giving people a choice, if a bunch of users decide cookies aren’t for them, the APIs in the sandbox might actually work for targeting them without cookies."

A "blessing in disguise" for advertisers does not read as an actual blessing to me.

Monday, June 10, 2024

Kenna and I slept in a bit today, then set out into downtown Perth. We grabbed breakfast at one of the many coffee shops. Perth seems to be quite a coffee city, but there are no Starbucks here.

We walked to Elizabeth Quay and the Barrack Street jetty, from which many tour boats originate. We picked up some information on Rottnest Island tours and were surprised when Lee and Colleen, two of our fellow passengers on the Orion, also showed up. We may see them again.

From there, we walked to Kings Park and its botanical garden. We made some wrong turns but eventually found it and discovered it is up quite a hill from downtown and has a great view. The botanical garden is nicely labeled and includes specific sections for areas like the Kimberley. From a distance, we saw Lee and Colleen here too. We could have spent a lot more time here, but we wanted to make it out to Fremantle, so we caught a bus to the train station and a train to Fremantle.

One of our first goals in Fremantle (“Freo” to the locals) was to visit the Indian Ocean for the first time. We went out to a nearby beach and touched the water, which, of course, felt like…water. Soon after that, we ran into a couple of other fellow passengers from the Orion, who had just returned from the Maritime Museum. They told us it was excellent, so we headed over there.

After a quick late lunch in their snack bar, we toured the exhibits. One memorable exhibit for me was Australia II, the Australian winner of the America’s Cup sailing race in 1983. It was a big deal at the time and continues to be a source of pride for Australians.

Fremantle hadn’t initially seemed much like other beach towns (Santa Cruz, Brighton UK, etc.) I have visited. But as we headed more into the city center, we began to see the makings of a beach town: some brewpubs, a game arcade, souvenir shops, etc. It was still somewhat more restrained than many.

Exhausted from several miles of walking, we returned to the train station and rode back to Perth, where we had more walking to do to get to the hotel. We opted to have dinner in the hotel’s pub, which was mediocre and surprisingly closed at 8 p.m. — earlier than most any pub I have seen.

The distinction is indeed important: it's akin to making an easy reader version, albeit one with the odd error here and there.

This is particularly important for newsrooms and product teams that are looking at AI to generate takeaways from articles. There's a huge chance that it'll miss the main, most pertinent points, and simply shorten the text in the way it sees fit.

Jiff is a brand new datetime library for Rust which focuses on "providing high level datetime primitives that are difficult to misuse and have reasonable performance". The API design is heavily inspired by the Temporal proposal for JavaScript.

The core type provided by Jiff is Zoned, best imagine as a 96-bit integer nanosecond time since the Unix each combined with a geographic region timezone and a civil/local calendar date and clock time.

The documentation is comprehensive and a fascinating read if you're interested in API design and timezones.

I didn’t post about it — what is there to say that hasn’t been said elsewhere? — but former President Trump was almost shot last week. The would-be assassin’s motive is muddy (he was a Republican), but the bullet or a sliver of glass narrowly missed him, taking a nip out of his ear. He’s been using it as political ammunition ever since, and the entire RNC, which started the following day, was in essence a stage show about toxic masculinity, featuring guests like Kid Rock, Hulk Hogan (who tore off his shirt to reveal another shirt with the Trump / Vance logo on it), and the CEO of the Ultimate Fighting Championship. At one point, during a Michigan rally following the event, Trump pulled a guy out of the crowd to remark how well-defined his arms were. His campaign, his policies, his demeanor are Idiocracy come to life.

As for his Vice Presidential candidate, I’d love to see a lot more people talking about JD Vance’s support for Curtis Yarvin, who believes in the reinstatement of slavery, in replacing the democratically elected government with a CEO king, and that Hitler was acting in self defense.

I have many differences with Joe Biden: most notably, his failure to take a strong stand against the ongoing slaughter in Gaza, and his war-faring foreign policy history throughout his career. But he’s not Donald Trump and he’s not JD Vance. Domestically, the Biden Presidency undoubtedly had some strong progressive successes over the last four years, in ways that genuinely helped vulnerable Americans. I voted for him in 2020. And certainly, were he the Democratic nominee, I would have voted for him again.

It seems almost certain that the Democratic nominee will be Kamala Harris. If that turns out to be the case, I’ll absolutely vote for her. With enthusiasm.

What I hope is that she can paint a picture of the world she wants to create. Biden never quite achieved that for me: he even memorably said to donors, that “nothing would fundamentally change” if he was elected. America needs change; it needs equity; it needs a renewed compassion, stronger safety nets, a leg up for people who need it, and a mentality that nobody should fall through the cracks. A focus on strong communities and bonds based on empathy rather than breaks for the rich and military might. A focus on a democratic, inclusive world and not just an American one. Beyond just not being Trump and not being Vance, those are my hopes for a Harris Presidency.

こんにちは、富士榮です。

世の中、ウォレットで溢れてきている今日この頃ですが皆さんお好みのウォレットは見つけられているのでしょうか?そしてそのウォレットで自分が使いたいサービスを使えているんでしょうか?さらにそのウォレットは信じて大丈夫なんでしょうか?

という話は置いておいて、一言でウォレットと言ってもいわゆるweb3的なウォレットもあればVerifiable CredentialsやmDocの様なアイデンティティ・ウォレットも存在するわけです。

今回は、皆さん大好きHackMDへのログインにウォレット(MetaMaskとかのweb3ウォレット)が使えるので使ってみただけのポストです。

セットアップは簡単で何らかの方法でログインした後でプロファイルのページからログイン方法を選択するだけです。

そして、なぜかウォレットログインを選択しようとするとパスワードの登録を求められるのでパスワードを設定するところからスタートです。何だか時代に逆行しているのか最先端をいっているのかよくわからなくなってきます。


パスワードを設定するとようやくログインに使うウォレットを選択するところにいきます。しかしweb3ウォレット、420+ってあります。本当に乱立しすぎです。

私は素直?にMetaMaskを選びましたが。



ブラウザにMetaMaskのプラグインが入っている環境なのでMetaMaskとの接続のポップアップが起動してきます。はい、1ETHも入っていません。。

普通にSNSログインと同じ様に許可をすると設定は終わりです。

次回からログインする際にウォレットを選択するとサインインできる様になります。

とっても簡単です。

ちなみにプラグインがブラウザに入っていない時はQRコードでスマホ側のウォレットを呼び出すこともできます。

この辺のUXはパスキーやVCとも共通ですね。一部ブラウザAPIがVCにも対応しようとしていますが、APIの共通化がもっと進むとUXの一貫性も保たれる様になると思うので、よりよくなりますね。

Sunday, June 9, 2024

Today started quite early because they needed to get us off the Orion early and prepare it in eight hours for the next cruise. We had our suitcases out for pickup at 7 a.m., ate breakfast, and exited the ship about 7:30. We had to go through Australian customs, which went smoothly for us but resulted in delays for some others, primarily some MDs who had medical supplies with them and one passenger who had bought a wooden oar somewhere along the way.

There were two busloads of passengers going to the airport. Our bus driver polled the passengers about our departure times and then took us on an impromptu bus tour of Darwin. Darwin is a surprisingly modern and clean city, and the driver was rightfully proud of his home town.

Darwin skyline

We arrived at the airport about three hours before our flight. Unfortunately, we couldn’t check our luggage until 90 minutes before flight time, so we had to wait outside security. There were enough of us there that we were able to use the time to reminisce about the cruise.

When the time came, we obtained our luggage tags and sent our bags down the conveyor. Unlike in the US, we just entered our names and destinations to check our luggage; no ID was required. Similarly, we went through security without showing an ID or our boarding passes, and there was no ID check getting onto the plane. This was very surprising to us!

The flight to Perth was uneventful. When we arrived in Perth, we found the climate to be very different. While it is the dry season in Darwin and the Kimberley coast, it is the wet season in Perth, which has a climate quite similar to the San Francisco Bay Area but shifted by six months. It was rainy and cloudy when we arrived.

When we got off the plane, we were surprised to see Dave’s friend Bruce and his wife waiting for us at the gate! That’s a consequence of not requiring a boarding pass to go through security and was a nice throwback to pre-9/11 practices.

We checked into our hotel, The Melbourne Hotel (yes, located in Perth), and found that we had booked a nicely outfitted but unusual guest room. For example, there was no door to any of the bathroom area; it was open to the bedroom. This is fine, but it takes a little getting used to.

Dave’s friend Bruce had made reservations for a lovely restaurant in North Fremantle,
Bib and Tucker. I had kangaroo for dinner, which had a nice flavor and is a very lean meat (accordingly cooked somewhat rare). Our hosts pointed out that the kangaroo they serve is farmed explicitly for that purpose.

After a very busy day, we said goodbye to Jan and Dave who left for the US that evening and to our hosts. We took the train from North Fremantle back to Perth, where we crashed.

I didn't think this was possible, since Code Interpreter is blocked from making outbound network requests.

Nico's trick uses a new-to-me feature of GPT Actions: you can return up to ten files from an action call and ChatGPT will download those files to the same disk volume that Code Interpreter can access.

Nico wired up a Val Town endpoint that can divide a PyPI wheel into multiple 9.5MB files (if necessary) to fit the file size limit for files returned to a GPT, then uses prompts to tell ChatGPT to combine the resulting files and test them as installable wheels.

W3C Verifiable Credentials Overviewが更新されました

こんにちは、富士榮です。 先月から読んできたW3C Verifiable Credential Overviewが少しだけ更新されています。 2024年6月13日版から2024年7月6日版への更新です。 まぁ、結果的にあまり大きな更新はありませんでした。サンプルが変わったくらいです。 ざっと変化点を。 1. サンプルの@Contextが変わった 3.2 Serialization in JSON Example1: @Contextに指定されているボキャブラリーが "https://www.example.org/vocabs/alumni" から、ネームスペース "https://www.w3.org/ns/credentials/examples/v2" へ変更されています。これは以降のExampleでも同様です。 2. サンプルの$idが変わった

こんにちは、富士榮です。

先月から読んできたW3C Verifiable Credential Overviewが少しだけ更新されています。

2024年6月13日版から2024年7月6日版への更新です。


まぁ、結果的にあまり大きな更新はありませんでした。サンプルが変わったくらいです。

ざっと変化点を。

1. サンプルの@Contextが変わった

3.2 Serialization in JSON

Example1:

@Contextに指定されているボキャブラリーが

"https://www.example.org/vocabs/alumni"

から、ネームスペース

"https://www.w3.org/ns/credentials/examples/v2"

へ変更されています。これは以降のExampleでも同様です。


2. サンプルの$idが変わった

同じくExample4では$idの値が、

"https://example.com/schemas/email.json"

から、

"https://university.example/schemas/credential.json"

へ変更されています。


3. JOSEに加えてCOSEのサンプルも載せようとしている

Example 6: A Simple Credential in JWT (unencoded)では前のバージョンではJOSEのサンプルだけだったのがCredential本体、JOSE、COSEの3つがタブで選択表示できるようになっています。だた、現状ではCredential部分しか書かれていないのでそのうちJOSEとCOSEのサンプルも書かれると思います。


4. ECDSAに加えてEdDSAのサンプルも載せようとしている

Example 8: the Core Example Secured with ECDSAの部分は、ECDSAだけのサンプルだったのがEdDSAのサンプルが追加されています。こちらもExample 6と同様にCredential本体、ECDSA、EdDSAでタブに分かれていますが、まだCredential本体部分しか記載がありません。


5. 完全なサンプルを纏めとして載せようとしている

最後にExample 12にComplete Exampleという形でVerifiable Credential with a Reference to a Credential Schema and to a Status ListがCredential本体、ECDSA、EdDSA、BBS、JOSE、SD-JWT、COSEのそれぞれでのサンプルが追記されようとしています。(同じくCredential部分しか書かれていない)


うん、まだまだ更新がかかるんだと思います。

英国、デジタルIDサービスを確立、データ共有を強化し、データ保護当局を改革する法案提出へ

「国王のスピーチ」に関する報告書のP.39〜41に、英国政府による新たなデジタル情報およびスマートデータ(Digital Information and Smart Data, DISD)法案の計画が述べられています。この法案は、データの力を経済成長、現代のデジタル政府の支援、お…

「国王のスピーチ」に関する報告書のP.39〜41に、英国政府による新たなデジタル情報およびスマートデータ(Digital Information and Smart Data, DISD)法案の計画が述べられています。この法案は、データの力を経済成長、現代のデジタル政府の支援、および人々の生活改善のために活用するもので、デジタル確認サービスの確立、オープンバンキングのスキームを他へ拡大するスマート・データ・スキームの設置、国家地下財産登録簿の整備、ICOの組織改革など、重要な点がいくつも含まれます。

これは、人々の生活をより便利にし、経済成長にもつながる、安全で安心なデジタルアイデンティティサービスを選択できるよう支援する法案です。新英国政府の第1回議会に提出される見込みです。

法案の動画版解説

法案の概要解説テキスト版

英国政府が新たなデジタル情報及びスマートデータ法案の提出を計画しています。この法案はデジタル時代における個人情報の取り扱いや経済成長に大きな影響を与える可能性があります。法案の目的はデータの力を活用して経済成長を促進し、近内的なデジタル政府を支援し、人々の生活を向上させることです。具体的にはデジタル確認サービスの確立、オープンバンキングの拡大、国家値財産登録簿の整理、情報コミッショナー事務局の改革などが含まれています。

デジタル確認サービスは安全で信頼できるデジタルIDの創出と採用を支援するものです。これにより引っ越しや雇用前チェック、年齢制限のある商品やサービスの購入など、日常生活の様々な場面で便利になることが期待されます。国家地下財産登録簿は地下にある配管やケーブルなどのインフラ情報をデジタル地図するものです。これにより工事や修理の際に必要な情報に素早くアクセスでき、作業の効率化と安全性の向上につながります。

スマートデータスキームは顧客の同意のもと、承認された第3者プロバイダーと顧客データを安全に共有する仕組みです。これは現在のオープンバンキングの概念を他の分野にも拡大するもので、より良いサービスや商品の提供につながる可能性があります。

またこの法案では、公共サービスのデジタル化も進められます。例えば出張や死亡の登録が電子システムに移行されたり、医療福祉システムのITサプライヤーに情報標準が適用されたりします。

科学研究の分野ではデータ法の現代化が図られます。科学者たちは研究のための包括的な同意を得やすくなり、商業的環境で研究を行うものも平等にデータ制度を利用できるようになります。これにより学際的な研究がより進みやすくなることが期待されます。

個人情報保護の面ではICOの組織改革と権限強化が行われます。CEOと取締役会議長を備えた現代的な組織構造に変革され、新たな権限も付与されます。これにより急速に進化するデジタル社会におけるプライバシー保護がより強化されることになります。またデジタルアイデンティティに関するプライバシー、セキュリティ、包摂性の基準も推進されます。これは誰もが安心してデジタルサービスを利用できる環境作りを目指すものです。

さらに子供の死亡に関する調査のためのデータ共有も改善されます。これにより悲劇的な事故の再発防止につながる可能性があります。

この法案はデジタル時代におけるデータの利活用を促進しそのデータを活用した経済船長や生活の質の向上を追求する試みと言えます。その中心に来るのが自分が何者であるかを表明することを支援するデジタル確認サービスとオープンバンキングをモデルに取ったスマートデータスキームであるということは大変興味深いことです。

しかしこの法案が実際にどのように運用されるのかどの程度の効果をもたらすのかについては、今後の展開を注視する必要があります。デジタル社会が急速に発展する中でこのような法整備は非常に重要ですが、同時に技術の進歩に法制度が追いつけるかどうかも課題となるでしょう。さらにこの法案な他国のデータ関連法制にどのような影響を与えるかも注目されます。GDPRと違い域外適用があるわけではありませんが英国のオープンバンキングは多くの国に影響を与えてきました。今回も同様に影響を与えるのか注視されます。

デジタル情報・スマートデータ法案説明和訳 政府は、経済成長のためにデータの力を確実に活用し、近代的なデジタル政府を支援し、人々の生活を向上させたいと考えています。 法案は、データの新たな革新的利用を安全に開発・展開することを可能にし、データ共有と基準を改革することで公共サービスをより良く機能させることで人々の生活を向上させ、データ法を改善することで科学者や研究者がより多くの生命を向上させる発見をするのを助け、規制当局(ICO)に新たな強力な権限とより近代的な構造を与えることであなたのデータが確実に保護されるようにします。これらの措置は、科学技術を通じて英国国民により良いサービスを提供するという政府の公約の実現に着手するものです。 法案の内容は? この法案は、データの力を経済成長のために活用するものです。わたしたちは、人々が参加することを選択でき、英国全体のイノベーション、投資、生産性を加速させる3つの革新的なデータ活用を法定化します。これには以下が含まれます: デジタル確認サービス1の確立:これは、革新的で安全な技術を通じて、人々の日常生活を容易にするものです。これらの措置は、認定されたプロバイダーが提供する安全で信頼できるデジタル・アイデンティティ製品およびサービスの創出と採用を支援するもので、引っ越し、雇用前チェック、年齢制限のある商品やサービスの購入などに役立ちます。 国家地下財産登録簿の開発:これは、私たちの足下に埋まっているパイプやケーブルの設置、保守、運用、修理の方法に革命をもたらす新しいデジタル地図です。これにより、設計者や掘削業者は、作業を効果的かつ安全に遂行するために必要なデータに、必要なときに、標準化された安全な方法で即座にアクセスできるようにります。 スマート・データ・スキームの設置:これは、顧客の要求に応じて、承認された第三者プロバイダーと顧客のデータを安全に共有するものです。 本法案は、人々の生活と人生のチャンスを向上させます。法案は、より多く、より良いデジタル公共サービスを可能にします。デジタル経済法を改正することで、公共サービスを利用する企業に関するデータを政府が共有できるようにします。出生と死亡の登録は電子システムに移行します。また、医療・福祉システムのITサプライヤーに情報標準を適用します。 この法案は、現代の学際的な科学研究の実態をデータ法に反映させることで、科学者たちが世界クラスの研究のためにデータをより有効に活用できるよう支援します。科学者たちは科学研究の広範な分野について包括的な同意を求めることができるようになり、また、商業的環境で科学研究を行う正当な研究者たちも、私たちのデータ制度を平等に利用できるようになります。 この法案はあなたのデータが十分に保護されることを保証します。我々は情報コミッショナー事務局(ICO)を近代化し、強化します。ICOは、CEOと取締役会、議長を備えたより現代的な規制構造に変革されます。そして、新たなより強力な権限を持つことになります。これに伴い、一部のデータ法に的を絞った改革が行われますが、これは高い保護基準を維持しつつ、現在、一部の新技術の安全な開発と展開を妨げている不明確さがある部分に対処するものです。また、プライバシー、セキュリティ、包摂性に関するデジタルアイデンティティの基準も推進します。 この法案はまた、検視官(そしてスコットランドでは検察官)が、子どもの死亡に関する調査を支援するために必要かつ適切だと判断した場合に開始できるデータ保存プロセスを確立します。これにより、検視官は子どもの死亡を調査する際に必要なオンライン情報へのアクセスが容易になります。 領土と適用範囲 法案は英国全土に拡大適用されます。 主な事実 デジタル検証サービスは、人々と企業が自信と安心をもって身元確認技術を最大限に活用できるよう支援します。デジタル検証サービスは、日常生活を送る中で自分自身に関することを証明するための便利で信頼できるオプションを提供することにより、人々の時間と費用を節約します。また、よりスムーズで安価、かつ安全なオンライン取引が可能になります。デジタル検証サービスは、コスト、時間、データ漏洩を削減することで、企業の日常的な負担を軽減します。安全なデジタル・アイデンティティが英国で広く使用されることによる経済効果は、年間約6億ポンドと見積もられています。 スマートデータとは、顧客(企業または消費者)の要求に応じて、顧客データをより広範で文脈のある「ビジネス」データで強化できる認定第三者プロバイダー2(ATP)と安全に共有することを指します。これらのATPは、意思決定や市場への関与を改善する革新的なサービスを顧客に提供します。オープンバンキングは、「スマートデータスキーム」というに値する制度の唯一の実施例ですが、永続的な基盤を確立し、そこから成長・拡大するために立法的枠組みが必要です。これにより、顧客はより情報に基づいた選択ができるようになり、企業にはイノベーションのためのツールキットが提供されます。消費者が自身のデータを各部門と共有できるようにすることで、オープンバンキングで見られた経済成長を経済全体に広げることも期待しています。これは特に、顧客の関与が低い市場や、企業が顧客よりも多くの情報やデータを保持している市場において重要です。 国家地下資産登録簿3(NUAR)は、私たちの足元に埋設されているパイプやケーブルの設置、保守、運用、修理の方法を革新する新しいデジタルマップです。NUARは、プランナーや掘削作業者に、効率的、効果的、そして安全に作業を行うために必要なデータへの標準化された、安全な、即時のアクセスを提供します。彼らが必要とする時に、必要なデータを得ることができます。 英国のデータ経済(データ市場と、データが経済の他部門に付加する価値)は、現在(2022年時点)GDPの推定6.9%を占めています。私たちはデータの力を活用することで、経済やより広範な社会に莫大な価値を生み出すことができます。英国のデータ経済は、貿易を促進するためにも極めて重要です。2021年には、データを活用した英国のサービス輸出はサービス輸出全体の85%を占め、その額は 2590億ポンドに上ると推定されます。英国からEUへのデータ対応輸出額だけでも910億ポンドと推定されます。 英国企業にとってデータは不可欠です。英国企業の77%が何らかの形でデジタルデータを扱っており、10人以上の従業員を抱える企業では99%に上ります。

Today is an at-sea day as we cross back over the Joseph Bonaparte Gulf to Darwin, where we will disembark from the Orion tomorrow morning. Again, the seas were rough, but not as much as the outgoing crossing. As with other at-sea days, there were lectures from the naturalists and an information session on future cruises. The day ended with the Captain’s cocktail reception and dinner. The cocktail reception featured a slideshow of photos that passengers had submitted (unfortunately, I misunderstood how to submit mine). There was also an auction of a specially-decorated flag from the ship to benefit the crew welfare fund and of a didgeridoo from Goyma’s family, the proceeds from which went back to his family. Happily, both auctions produced high bids for the beneficiaries.

For dinner, Dave and Jan were kind enough to join us in the COVID dining area for our final dinner on the Orion. It was a particularly good dinner, and we witnessed a beautiful sunset and moonset.

LLMs look like they work, and they look generalised, and they look like a product - the science of them delivers a chatbot and a chatbot looks like a product. You type something in and you get magic back! But the magic might not be useful, in that form, and it might be wrong. It looks like product, but it isn’t. [...]

LLMs look like better databases, and they look like search, but, as we’ve seen since, they’re ‘wrong’ enough, and the ‘wrong’ is hard enough to manage, that you can’t just give the user a raw prompt and a raw output - you need to build a lot of dedicated product around that, and even then it’s not clear how useful this is.

Friday, June 7, 2024

I checked in with Dr. Bob early this morning to remind him that I needed to be checked and cleared to take today’s helicopter flight to Mitchell Falls. He told me that I had been diagnosed too recently and had to be removed from the flight list. I was disappointed. I pointed out that I had been diagnosed at 7:45 a.m. the previous day, and the cutoff time was given as 8:00. But after further consultation, he called back and said I was good to go because the helicopter ride was somewhat after 8:00.

We made a Zodiac boat transfer to a nearby beach. A few minutes later, three helicopters landed on the beach. We met our pilot and were given a safety briefing (tl;dr: STAY AWAY FROM THE SPINNING ROTORS). Dave and Jan were the other passengers on the helicopter with us. I had the left front seat next to the pilot (who sat on the right, as if we were flying on the left side of the sky).

With an open window next to me, the view was, as expected, gorgeous (both in the sense of attractiveness and the presence of gorges). We rode the 30 miles up the Mitchell River to the falls, mostly admiring the terrain as no particular animals were visible.

On arrival, we hiked up a short trail to get several good views of Mitchell Falls. We had enough time to explore the rocky terrain in the area before returning to the helicopter landing area for our trip back to the beach. The return trip was equally awesome.

For lunch, I joined in with others who had also tested COVID-positive and ate separately from others on the observation deck. This precaution was taken because, even though we were eating outside, eating is one of the times when it is easiest to spread the virus. The upper deck was enjoyable and quiet, although we noticed that several people who we knew had tested positive weren’t there.

After lunch, we had an informative lecture and a trip to another native art site. This schedule was coordinated with another (somewhat larger) ship in the area, Le Jacques Cartier, that we had also seen this morning when visiting Mitchell Falls. Unfortunately, the art site wasn’t big enough to accommodate both ships simultaneously, and we went second. The tide was very low when we went, so we had a very long (and delayed) zodiac boat ride to shore. We had to climb shore rocks to get to where the art was, which was slow for some visitors.

There was quite a bit of Indigenous art to look at, but before we could see it all, an urgent call was put out to return to the zodiac boats because the tide had fallen further. We climbed back down the rocks and waded out farther to reach the zodiac boats. We were disappointed not to have enough time to admire the rest of the art.

Today’s delicious dinner was an “Aussie BBQ” with all the trimmings, which I ate with my fellow COVID patients. After dinner, there was a talent show featuring many of the cooks, waiters, and porters from the hotel staff. It was a nice way to introduce them more personally.

I've been using the pattern where you add cache: pip to the actions/setup-python block, but it has two disadvantages: if the tests fail the cache won't be saved at the end, and it still spends time installing the packages despite not needing to download them fresh since the wheels are in the cache.

Adam's pattern works differently: he caches the entire .venv/ folder between runs, avoiding the overhead of installing all of those packages. He also wraps the block that installs the packages between explicit actions/cache/restore and actions/cache/save steps to avoid the case where failed tests skip the cache persistence.

Quoting Andrej Karpathy

The reason current models are so large is because we're still being very wasteful during training - we're asking them to memorize the internet and, remarkably, they do and can e.g. recite SHA hashes of common numbers, or recall really esoteric facts.

The reason current models are so large is because we're still being very wasteful during training - we're asking them to memorize the internet and, remarkably, they do and can e.g. recite SHA hashes of common numbers, or recall really esoteric facts. (Actually LLMs are really good at memorization, qualitatively a lot better than humans, sometimes needing just a single update to remember a lot of detail for a long time). But imagine if you were going to be tested, closed book, on reciting arbitrary passages of the internet given the first few words. This is the standard (pre)training objective for models today. The reason doing better is hard is because demonstrations of thinking are "entangled" with knowledge, in the training data.

Therefore, the models have to first get larger before they can get smaller, because we need their (automated) help to refactor and mold the training data into ideal, synthetic formats.

It's a staircase of improvement - of one model helping to generate the training data for next, until we're left with "perfect training set". When you train GPT-2 on it, it will be a really strong / smart model by today's standards. Maybe the MMLU will be a bit lower because it won't remember all of its chemistry perfectly.

Upgrades to LLM to support the latest models, and a whole bunch of invisible work building out a staging environment for Datasette Cloud.

GPT-4o mini and LLM 0.15

Today's big news was the release of GPT-4o mini, which I wrote about here. If you build applications on top of LLMs this is a very significant release - it's the cheapest of the high performing hosted models (cheaper even than Claude 3 Haiku and Gemini 1.5 Flash) and has some notable characteristics, most importantly the 16,000 token output limit.

I shipped a new LLM release to support the new model. Full release notes for LLM 0.15:

Support for OpenAI's new GPT-4o mini model: llm -m gpt-4o-mini 'rave about pelicans in French' #536 gpt-4o-mini is now the default model if you do not specify your own default, replacing GPT-3.5 Turbo. GPT-4o mini is both cheaper and better than GPT-3.5 Turbo. Fixed a bug where llm logs -q 'flourish' -m haiku could not combine both the -q search query and the -m model specifier. #515
sqlite-utils 3.37

LLM had a frustrating bug involving a weird numpy issue that only manifested on LLM when installed via Homebrew. I ended up fixing that in its sqlite-utils dependency - here are the full release notes for sqlite-utils 3.37:

The create-table and insert-files commands all now accept multiple --pk options for compound primary keys. (#620) Now tested against Python 3.13 pre-release. (#619) Fixed a crash that can occur in environments with a broken numpy installation, producing a module 'numpy' has no attribute 'int8'. (#632)
Datasette Cloud staging environment

I'm a big believer in reducing the friction involved in making changes to code. The main reason I'm so keen on the combination of automated tests, GitHub Actions for CI/CD and extensive documentation (as described in Coping strategies for the serial project hoarder) is that

Sadly, Datasette Cloud hasn't been living up these standards as much as I would like. I have great comprehensive tests for it, continuous deployment that deploys when those tests pass and pretty solid internal documentation (mainly spread out across dozens of GitHub Issues) - but the thing I've been missing is a solid staging environment.

This matters because a lot of the most complex code in Datasette Cloud involves deploying new instances of Datasette to Fly Machines. The thing that's been missing is a separate environment where I can exercise my Fly deployment code independently of the production cluster.

I've been working towards this over the past week, and in doing so have found all sorts of pieces of the codebase that are hard-coded in a way that needs to be unwrapped to correctly support that alternative environment.

I'm getting there, but it's been one of those frustrating projects where every step forward uncovers at least one more tiny problem that needs to be resolved.

A lot of these problems relate to the GitHub Actions workflows being used to build, test and deploy my containers. Thankfully Claude 3.5 Sonnet is great at helping refactor GitHub Actions YAML, which has been saving me a lot of time.

I'm really looking forward to wrapping this up, because I plan to celebrate by shipping a flurry of Datasette Cloud features that have been held up by the lack of a robust way to extensively test them before sending them out into the world.

MyData Japanカンファレンスに見るアイデンティティのモデル

一昨日はMyData Japanカンファレンスに行ってきました。 OpenIDファウンデーションジャパンも後援させていただいています。
イベントページ https://mydatajapan.org/events/mydata-japan-2024/
界隈の人たちはみんないたんじゃないかな?という位、自分がフォローしている人のタイムラインを見ていれば行かなくても済むくらいの盛況でした(謎)。
もちろん午前中のデジタルアイデンティティ関連のセッションを中心に見たわけですが改めてMyDataが整理しているアイデンティティモデルはよくできているな〜と思ったのでその部分だけ。 詳しくは崎村さんのブログで資料も公開されていますので。 https://www.sakimura.org/2024/07/6129/
崎村さんの資料では日本語になっていますが、原典のMyDataの説明では以下の図で解説されています。 https://mydata.org/participate/declaration/
MyDataのページより

これが程よい抽象化レベルで非常にわかりやすいし、汎用的だなぁ、と改めて。
MyDataのページによるとそれぞれのアクターは以下の役割を持つ、と定義されています。 PERSON An individual that manages the use of their own personal data, for their own purposes, and maintains relationships with other individuals, services or organisations. DATA SOURCE A data source collects and processes personal data which the other roles (including Persons) may wish to access and use. DATA USING SERVICE A data using service can be authorised to fetch and use personal data from one or more data sources. PERSONAL DATA OPERATOR A Personal Data Operator enables individuals to securely access, manage and use their personal data, as well as to control the flow of personal data with, and between, data sources and data using services. Individuals can be their own operator. In other cases, operators are not using the information itself, but enabling connectivity and secure sharing of data between the other roles in the ecosystem. (DeepLで翻訳) PERSON 自身の個人情報を自身の目的のために管理し、他の個人、サービス、組織との関係維持を行う個人。 データソース データソースは、他の役割(Personを含む)がアクセスし、使用したいと思う可能性のある個人情報を収集し、処理します。 データ利用サービス データ利用サービスは、1つまたは複数のデータソースから個人情報を取得し、使用することを許可される場合があります。 個人データオペレーター 個人データオペレーターは、個人が自身の個人データに安全にアクセスし、管理し、使用できるようにするとともに、データソースとデータ使用サービスとの間で、またデータソース間での個人データの流れを制御できるようにします。個人が自身のオペレーターになることもできます。その他の場合、オペレーターは情報そのものは使用せず、エコシステム内の他の役割との間でデータの接続と安全な共有を可能にします。 例えばOpenID Connectなどのフェデレーションモデルでは、Personが利用者、データソースがIdentity Provider、データ利用サービスがRelying Party、Verifiable CredentialsのモデルだとデータソースであるIssuerとデータ利用サービスであるVerifierの間にWalletが入るわけです。 そして、最も重要なポイントは個人データオペレーターの存在です。 フェデレーションのモデルにおいてはIdentity Providerが個人データオペレーターを兼ねることになりますし、典型的なVerifiable Credentialsの利用モデルにおいてはWalletプロバイダが個人データオペレーターになったりするわけです。
結局のところ個人データを誰かが扱うことになるので、自己主権型アイデンティティを実現するにはこの個人データオペレーターを個人が完全に制御できる状態を作る必要が出てくるわけです。Walletがあれば自己主権ってわけじゃないぞ、というのがよくわかりますね。結局はWalletプロバイダに頼ってしまうわけです。
だからガバナンスが大事になるわけですね。
この辺りが通常のアイデンティティモデルの図にはあまり出てこないので、改めてこの図を見ると理解が深まるんじゃないかな、と思いました。

LLM 0.15

A new release of my LLM CLI tool for interacting with Large Language Models from the terminal (see this recent talk for plenty of demos).

This release adds support for the brand new GPT-4o mini:

llm -m gpt-4o-mini "rave about pelicans in Spanish"

It also sets that model as the default used by the tool if no other model is specified. This replaces GPT-3.5 Turbo, the default since the first release of LLM. 4o-mini is both cheaper and way more capable than 3.5 Turbo.

GPT-4o mini

I've been complaining about how under-powered GPT 3.5 is for the price for a while now (I made fun of it in a keynote a few weeks ago).

GPT-4o mini is exactly what I've been looking forward to.

It supports 128,000 input tokens (both images and text) and an impressive 16,000 output tokens. Most other models are still ~4,000, and Claude 3.5 Sonnet got an upgrade to 8,192 just a few days ago. This makes it a good fit for translation and transformation tasks where the expected output more closely matches the size of the input.

OpenAI show benchmarks that have it out-performing Claude 3 Haiku and Gemini 1.5 Flash, the two previous cheapest-best models.

GPT-4o mini is 15 cents per millions input tokens and 60 cents per million output tokens - a 60% discount on GPT-3.5, and cheaper than Claude 3 Haiku's 25c/125c and Gemini 1.5 Flash's 35c/70c. Or you can use the OpenAI batch API for 50% off again, in exchange for up-to-24-hours of delay in getting the results.

It's also worth comparing these prices with GPT-4o's: at $5/million input and $15/million output GPT-4o mini is 33x cheaper for input and 25x cheaper for output!

OpenAI point out that "the cost per token of GPT-4o mini has dropped by 99% since text-davinci-003, a less capable model introduced in 2022."

One catch: weirdly, the price for image inputs is the same for both GPT-4o and GPT-4o mini - Romain Huet says:

The dollar price per image is the same for GPT-4o and GPT-4o mini. To maintain this, GPT-4o mini uses more tokens per image.

Also notable:

GPT-4o mini in the API is the first model to apply our instruction hierarchy method, which helps to improve the model's ability to resist jailbreaks, prompt injections, and system prompt extractions.

My hunch is that this still won't 100% solve the security implications of prompt injection: I imagine creative enough attackers will still find ways to subvert system instructions, and the linked paper itself concludes "Finally, our current models are likely still vulnerable to powerful adversarial attacks". It could well help make accidental prompt injection a lot less common though, which is certainly a worthwhile improvement.

Mistral NeMo

Released by Mistral today: "Our new best small model. A state-of-the-art 12B model with 128k context length, built in collaboration with NVIDIA, and released under the Apache 2.0 license."

Nice to see Mistral use Apache 2.0 for this, unlike their Codestral 22B release - though Codestral Mamba was Apache 2.0 as well.

Mistral's own benchmarks but NeMo slightly ahead of the smaller (but same general weight class) Gemma 2 9B and Llama 3 8B models.

It's both multi-lingual and trained for tool usage:

The model is designed for global, multilingual applications. It is trained on function calling, has a large context window, and is particularly strong in English, French, German, Spanish, Italian, Portuguese, Chinese, Japanese, Korean, Arabic, and Hindi.

Part of this is down to the new Tekken tokenizer, which is 30% more efficient at representing both source code and most of the above listed languages.

You can try it out via Mistral's API using llm-mistral like this:

pipx install llm llm install llm-mistral llm keys set mistral # paste La Plateforme API key here llm mistral refresh # if you installed the plugin before llm -m mistral/open-mistral-nemo 'Rave about pelicans in French'

Apple, Nvidia, Anthropic Used Thousands of Swiped YouTube Videos to Train AI

This article has been getting a lot of attention over the past couple of days.

The story itself is nothing new: the Pile is four years old now, and has been widely used for training LLMs since before anyone even cared what an LLM was. It turns out one of the components of the Pile is a set of ~170,000 YouTube video captions (just the captions, not the actual video) and this story by Annie Gilbertson and Alex Reisner highlights that and interviews some of the creators who were included in the data, as well as providing a search tool for seeing if a specific creator has content that was included.

What's notable is the response. Marques Brownlee (19m subscribers) posted a video about it. Abigail Thorn (Philosophy Tube, 1.57m subscribers) tweeted this:

Very sad to have to say this - an AI company called EleutherAI stole tens of thousands of YouTube videos - including many of mine. I’m one of the creators Proof News spoke to. The stolen data was sold to Apple, Nvidia, and other companies to build AI

When I was told about this I lay on the floor and cried, it’s so violating, it made me want to quit writing forever. The reason I got back up was because I know my audience come to my show for real connection and ideas, not cheapfake AI garbage, and I know they’ll stay with me

Framing the data as "sold to Apple..." is a slight misrepresentation here - EleutherAI have been giving the Pile away for free since 2020. It's a good illustration of the emotional impact here though: many creative people do not want their work used in this way, especially without their permission.

It's interesting seeing how attitudes to this stuff change over time. Four years ago the fact that a bunch of academic researchers were sharing and training models using 170,000 YouTube subtitles would likely not have caught any attention at all. Today, people care!

The Pragmatic Engineer

The Pulse #101: Did AWS forget it’s a cloud infra company?

Also: why GitLab is seeking a buyer, how Alexa got left behind in conversational AI, and Cloudflare offering customers less AI – because those customers want this.

The Pulse is a series covering insights, patterns, and trends within Big Tech and startups. Notice an interesting event or trend? Send me a message.

Today, we cover:

Industry pulse. Google to buy cybersecurity startup Wiz for $23B, Snowflake quiet on messy data breaches, Claude’s new model wows developers, poor web UX creates random Icelandic presidents-in-waiting, and more.

Did AWS forget it’s a cloud infra company? AWS seems to spend most of its developer investment and innovation on GenAI, which is starting to annoy their core customer base of cloud engineers. But is this strategy more rational than it seems?

Why is GitLab seeking a buyer? Two weeks after we highlighted that GitLab’s business has grown faster than most SaaS businesses, the source control company is looking for a buyer. Looking closer, GitLab’s impressive revenue numbers might be due to higher prices, while real business growth may be more ordinary than it appears.

How did Alexa get left behind in conversational AI? In 2019, Alexa had 100M users, and Amazon was investing billions in research and development. A former Amazon ML engineer shares what they think led to Amazon missing the opportunity for Alexa to be the conversational agent ChatGPT has become.

Cloudflare offers customers less AI – because they want it. There is no shortage of businesses rolling out GenAI features to attract new customers. In contrast, Cloudflare has listened to its customers and is doing the opposite: rolling out a feature that allows customers to block GenAI crawlers from their data. This move will likely make it more expensive to source GenAI training data, globally.

1. Industry pulse Google bids big for Wiz security scaleup

Wiz is an Israeli cybersecurity scaleup, founded 4.5 years ago. Last month, we reported the company was a potential buyer of another cybersecurity scaleup, Lacework, raised $1.9B and was last valued at $8.3B. Lacework explored a sale to Wiz, as per The Information, which offered $100M; a sum equal to the annual revenue of Lacework, which hasn’t grown in the past several years because of continuous customer churn.

This week, the WSJ reported Google is close to acquiring Wiz for $23B, which would make it the search giant’s largest acquisition yet, and be a massive increase on Wiz’s $10B valuation from 2023.

It’s unusual to see a 4-year-old startup be so in demand, especially in an enterprise sales-heavy industry like cybersecurity. For cybersecurity companies to strike deals, they typically need to convince chief information security officers (CISOs) to sign longer-term contracts, which is easier said than done: even after Lacework raised $1.9B in funding, the company is “only” managing to generate $100M/year in revenue. This is a testament to this!

Plenty of people want to know how Wiz attracted such a high offer. Last summer, Forbes published a deep dive on Wiz’s success, “Nobody beats Wiz,” in which Forbes revealed Wiz’s hyper-aggressive sales strategy of closing the market’s highest-value companies first, and cutthroat negotiation tactics. Last month, Israeli publication Calcaist also revealed how one of Wiz’s investor, Cyberstarts, could have played a large role in driving Wiz sales.

It’s an open secret that investors can and do make a big difference for startups in the market for a sale. This is because of industry contacts: investors introduce businesses to others in their portfolio, meaning a scaleup selling a solution for tech companies could access new corporate customers via these introductions. 

My take is that the success of Wiz is truly remarkable, and its investors likely have a big role in this. But most credit should go to Wiz employees; they’ve been able to grow in a very competitive market like cybersecurity.

Thursday, June 6, 2024

I felt a little stuffy this morning, and given the ship’s COVID outbreak, I decided to get tested. I called Dr. Bob, the ship’s doctor, who came by with a couple of swabs, one for me and one for Kenna. A few minutes later, he called back with the result: I had tested positive, but Kenna was negative. He returned a little while later to check my vitals, listen to my lungs, and deliver Paxlovid, which I had taken on both of my previous COVID cases.

The ship’s protocol for handling this was straightforward: I needed to isolate myself in our room for 24 hours, and Kenna should stay away as much as possible. Breakfast, lunch, and dinner menus appeared on my cabin door. I selected meals, which were delivered to me in the room. Since the cruise ends on Sunday, I will need to wear a mask on the ship for a few days for the rest of the cruise.

Kenna went out to eat with the rest of the ship (specifically with Jan and Dave, whom we had spent time with) and then went on the day’s activities. The morning activity was a ride to see Thor’s Hammer, a tall sandstone rock formation. Kenna’s Zodiac was piloted by Karla, the expedition leader, and paired with Kurt, the geologist, in another Zodiac. Between the two, the group got a good geology lesson with specimens of quartz crystals that Karla borrowed from a rocky outcrop where they stopped.

The afternoon excursion was their best opportunity to see crocodiles as the tide was going out on Porosus Creek. They were still a little early, but after a while finally got a few sightings including a chance to watch a crocodile devour a crab, before having to return to the ship.

There was also a briefing for tomorrow’s helicopter trip. The helicopter company was consulted to see if they would permit masked Covid-positive people on the helicopters, and they said it was OK, provided they were diagnosed before 8 am today (I was diagnosed about 7:45). Whew. I will still need to be checked to see if I’m running a fever (I wasn’t today), so my fingers are crossed that I can go.

My day was mostly spent reading and doing consulting work since I had to stay in the cabin anyway.

In the evening, Kenna was told they had found another place for her to sleep to minimize her exposure. It is a cabin for harbor pilots to use when necessary. We appreciate the creativity of the hotel manager, Fran, in finding this for her. Fran has been amazing through this entire cruise, and this evening brought Kenna a night light to use in the temporary cabin.

"So what does Vance think? He is in agreement with the views of a rising set of younger conservatives, populists like Sohrab Ahmari and Oren Cass, who assert that libertarianism is a cover for private rule, most explicitly in Ahmari’s book Tyranny, Inc. It is flourishing of the family that animates this new group, not worship of the market. At Remedy Fest, Vance was explicit in his agreement with this notion, saying “I don't really care if the entity that is most threatening to that vision is a private entity or a public entity, we have to be worried about it.”"

An interesting analysis of JD Vance's economic ideas - at least as described here, I'm actually not in disagreement. The free market is cover for private rule. Lina Khan is doing a great job.

I'm less impressed with his backers Andreessen and Horowitz's ideas, which are tied up with military might and a self-interested misunderstanding of what happened in relation to the downfall of the USSR. The idea that Elizabeth Warren "hates capitalism" is nonsense. It's a very thin defense drawn from their particular mode of capitalism coming under threat of regulation.

The trouble is, as I've described, all the social policies that go along with it. Sure, try and influence both political parties to be beneficial to your businesses all you want. But if you throw mass deportations, military policing of our cities, and fascist reconstructions of government in the mix, you'd better be ready for the repercussions.

"Apple’s decision to strike a deal with Taboola is shocking and off-brand — so much so that I have started to question the company’s long-term commitment to good customer experience, including its commitment to privacy."

This move says a lot about modern Apple, but more than that, it likely says a lot about the performance of Apple News.

For many news publishers Apple News pageviews are a multiple of the reads on their own websites: it's a serious source of traffic and impact. The fact that Apple is finding itself having to make changes to how it makes revenue on the platform means that the mechanism itself may be under threat.

It's never a good idea to put your trust in a third party: every publisher needs to own their relationships with their communities. The pull of Apple News has been irresistible, and Apple has seemed more trustworthy than most. This may have been a false promise, and publishers should take note.

News CEOs and the Question of News Experience

[Richard J. Tofel] "I think some of those choosing these new business leaders themselves forgot about the special nature of the news business.

[Richard J. Tofel]

"I think some of those choosing these new business leaders themselves forgot about the special nature of the news business. It won’t be enough, for instance, at least in most cases, for someone who aspires to run a news organization to recognize the importance of the role of the press in democratic governance—although that ought to be essential."

"[...] More subtly, a CEO without news experience may not grasp how large of an asset is newsroom morale, or how much sapping it may cost an enterprise. Such issues can become particularly tricky in a unionized environment— especially one in which there are no profits over which to haggle, either because the organization is a nonprofit, or because it is no longer profitable."

Dick Tofel was the founding general manager of ProPublica, and generally knows a thing or two about the news business.

There's a line to walk here: there's certainly risk, as Tofel describes, of picking a news CEO who is not familiar with the news business. At the same time, as I've previously lamented, the industry needs an injection of new, outside ideas. It's certainly true that the CEO must deeply understand how news works, but they also can't be to afraid to change some of those dynamics - as long as they're cognizant of the position and responsibility that journalism holds in a democracy.

Any CEO needs to be very aware of organizational culture and morale. Many news CEOs are hyper-focused on their journalism (which is good!) at the expense of thinking too deeply about culture (which is bad). Hopefully any good incoming CEO would be an expert at building culture, although most of us know that this often isn't the case.

It's complicated, in other words. But journalism is at least as important as it's ever been, and getting news leadership right is crucial.

The Silicon Valley Would-Be Vice President

JD Vance is an obvious, bald-faced opportunist. It makes sense that Trump would pick him as his Vice Presidential candidate; they probably understand each other quite well.

It can’t have hurt that a bevy of tech billionaires told Trump to pick him, and it’s not unreasonable to assume they gated funding on that choice. Elon Musk has pledged to give $45 million a month to a PAC newly formed to back Trump; Palantir co-founder Joe Lonsdale, former Yammer founder David Sacks, and VC Chamath Palihapitiya have also raised money for the group. Eponymous Andreessen-Horowitz founders Marc Andreessen and Ben Horowitz pledged donations and Keith Rabois has also reportedly pledged a comparatively paltry $1 million. (The Winkelvoss twins are also donors, but I wouldn’t exactly call them Silicon Valley insiders.)

Andreessen explained why, saying that the future of America is at stake:

Biden’s proposal to tax unrealized capital gains is what Andreessen called “the final straw” that forced him to switch from supporting the current president to voting for Trump. If the unrealized capital gains tax goes into effect, startups may have to pay taxes on valuation increases. (Private companies’ appreciation is not liquid. However, the U.S. government collects tax in dollars.)

One could argue, of course, that the future of America is at stake. As The 19th reported about Project 2025, the Heritage Foundation’s suggested plan for a next Trump administration whose authors include over 140 people who were a part of the last one:

Much of Project 2025 relates to gender, sexuality and race, aiming to end most all of the federal government’s efforts to achieve equity and even collect data that could be used to track outcomes across the public and private sectors.

The other sweeping changes it proposes include firing civil servants and replacing them with Trump loyalists, removing the Department of Education, gutting our already-insufficient climate change protections, reinstating the military draft, conducting sweeping immigration raids and mass deportations, and condemning more people to death sentences while making them swift enough to avoid retrial.

All this despite being on shaky legal ground:

Some of these ideas are impractical or possibly illegal. Analysts are divided about whether Trump can politicize the civil workforce to fire them at will, for example. And the plan calls for using the military to carry out mass deportations on a historic scale, which could be constitutionally iffy.

Trump has lately distanced himself from the plan in public, but privately said something quite different at a Heritage Foundation dinner:

“This is a great group and they’re going to lay the groundwork and detail plans for exactly what our movement will do, and what your movement will do, when the American people give us a colossal mandate to save America.”

For his part, Kevin Roberts, the President of the Heritage Foundation, said out loud on Steve Bannon’s podcast:

We are in the process of the second American Revolution, which will remain bloodless if the left allows it to be.

JD Vance is walking this line too. My employer, ProPublica, recently reported that he, among other things, believes that the Devil is real, and that he had some unpleasant things to say about trans people:

He said that Americans were “terrified to tell the truth” and “point out the obvious,” including that “there are real biological, cultural, religious, spiritual distinctions between men and women.” He added, “I think that’s what the whole transgender thing is about, is like fundamentally denying basic reality.”

So, yes, all things considered, it feels a bit like America is in the balance.

What’s particularly bald about involvement from the Silicon Valley crowd is that they are, according to them, overlooking all of this and concentrating solely on their business interests. If policies like a tax on unrealized capital gains or tighter anti-trust actions are enacted, those investors may have to re-think some of their investment strategies.

For what it’s worth, those taxes are only applicable for individuals with a net worth of over $100M, with payments at an automatic minimum tax rate treated as prepayments against future realized gains. The effect could actually be to encourage startups to go public and realize their value sooner, which wouldn’t be a terrible thing for the ecosystem (but might limit the heights private valuations can reach). Given that people with that level of worth don’t usually make taxable income, this new levied tax on investment gains makes sense as a way to encourage the very wealthy to pay the same sorts of tax rates as the rest of us — but, clearly, Musk, Thiel, et al feel differently. (Invasive thought: where’s Sacks and Palihapitiya’s podcast co-host Jason Calacanis on this? Is he a sympathizer or just an enabler?)

Do tighter regulations and a new minimum tax for the wealthy risk the future of America, though? Maybe they have a different definition of America than I do. If, to them, it’s a place where you can make a bunch of money without oversight or accountability, then I can see how they might be upset. If, on the other hand, America is a place where immigrants are welcome and everyone can succeed, and where everyone has the freedom to be themselves, all built on a bedrock of infrastructure and support, then one might choose to take a different view. The tax proposal at hand is hardly socialism; it’s more like a correction. Even if you accept their premise, single-issue voting when the other issues include mass deportations and gutting public education is myopically self-serving, leave alone the barren inhumanity of leaving vulnerable communities out to dry.

Responses by prominent Republican supporters to the inclusion of a Sikh prayer in Punjabi in the Republican National Convention — one line reading, “in your grace and through your benevolence, we experience peace and happiness” — lay bare what the unhinged Christian nationalist contingent believes in:

Andrew Torba, CEO of the far-right social media platform Gab, ranted to his 400,000 followers on X, “Last night you saw why Christian Nationalism must be exclusively and explicitly Christian. No tolerance for pagan false gods and the synagogue of Satan.” Republican Oklahoma state Sen. Dusty Deevers seemed to agree. “Christians in the Republican party nodding silently along to a prayer to a demon god is shameful,” he posted.

From my perspective, there are no upsides to a Trump win. Even if you accept the idea that Project 2025 has nothing to do with him (which, as I’ve discussed, is laughable), his own self-published Agenda 47 for his next administration is similarly horrible, and includes provisions like sending the National Guard into cities, destroying climate crisis mitigations, mass deportations, and removing federal funding for any educational institution that dares to teach the history of race in America. It also includes a version of Project 2025’s call to fire civil servants who are seen as disloyal. JD Vance wants to end no-fault divorce(ironically, given his running mate), trapping people in abusive relationships. The effects on the judicial system from his first administration will be felt for generations; a second administration will be similarly seismic. He will gut support for vulnerable communities. I have friends who will directly suffer as a result of his Presidency; he will create an America that I do not want to bring my son up in.

Silicon Valley is supposed to invent the future. That’s what’s so inspiring about it: for generations, it’s created new ways of sharing and working that have allowed people to communicate and work together wherever they are. These new moves make it clearer than ever that a portion of it has never believed in that manifesto; that it is there solely to establish itself as a new set of power-brokers, trying to remake the world in their own image. The rest of us need to oppose them with our full voices and everything we can muster.

昨年のIGFでTrusted Data Intermediary を取り上げましたが、関係するトピックだと思いました。主なポイントは以下のようです。

主なポイント はじめに 急速な技術的・経済的発展により、情報と権力の非対称性が生じている。 データ権利は、これらの非対称性を緩和するための解放的な法的ツールである。 データ権利とその重要性 データ権利の重要性が増し、これらがエンパワーメントの手段として登場している。 GDPRの第III章はデータ主体の権利に関する主要な法的ソースである。 データ権利には、アクセス、訂正、抹消、ポータビリティ、異議、および自動化された意思決定に対する保護が含まれる。 データ権利仲介者(DRIs) DRIsは、データ権利の集団的行使を促進または仲介する役割を果たす。 データ主体の基本的、不可譲の性質を損なうことなく、データ権利はDRIsに委任できる。 委任により、DRIsはさまざまな文脈でデータ主体を代理して行動することが可能になる。 データ権利の委任に関する法的枠組み GDPRやデータガバナンス法におけるデータ権利の委任についての不明確な点が存在。 委任は契約に類似し、契約法の原則と信託義務に従う必要がある。 信託義務と規制の重要性 信託義務がDRIの操作の枠組みを提供する可能性がある。 委任は明確、具体的であり、制度的な監視と結びついている必要がある。 システムの透明性とコンプライアンス問題の影響 システム的な問題は、公正で効果的なデータ権利の行使を妨げている。 DRIsは、データ主体が直面する技術的、法的、財政的な障壁を克服するのに役立つ。 データ権利の集団的行使は、システム的な不正を打ち負かす可能性を持っている。 結論 DRIsにデータ権利を委任することは、データ駆動の社会的不正を解決する上で重要な一手となりえる。 効果的で説明責任のあるDRIsを確保するための頑強な法的および制度的枠組みが必要である。

AI Tooling for Software Engineers in 2024

Gergely Orosz reports back on the survey he ran of 211 tech professionals concerning their use of generative AI. One interesting result:

The responses reveal that as many professionals are using both ChatGPT and GitHub Copilot as all other tools combined!

I agree with Gergely's conclusion:

We’re in the midst of a significant tooling change, with AI-augmented software engineering becoming widespread across tech. Basically, these tools have too many upsides for developers to ignore them: it’s easier and faster to switch between stacks, easier to get started on projects, and simpler to become productive in unfamiliar codebases. Of course there are also downsides, but being aware of them means they can be mitigated.

Wednesday, June 5, 2024

Today’s breakfast came with an announced request to allow the COVID-infected people to pick up breakfast first, after which they would clean the serving utensils and invite the rest of us for breakfast. We were asked to wash our hands at a sink on the back deck to limit any further spread.

Today’s activities consisted of two outings in Zodiac boats, which we just toured and didn’t land anywhere. The morning cruise was around a few nearby islands and into a mangrove-lined area where we hoped to see some crocodiles. We didn’t see any, but we did see some birds and the stunning local geology, and we were treated to some more stories from Goyma, our indigenous guide, who happened to be on our zodiac boat.

Around lunchtime, I ran into Dr. Bob, our ship physician. He said there was a “trickle” of additional COVID cases but that some had recovered, none of the existing cases were severe, and most patients were taking Paxlovid. This is probably appropriate considering most passengers’ ages (we estimate the median age at 73).

After another ship repositioning, we were off on zodiac boats to Montgomery Reef, a unique reef formation. The reef is just below sea level at high tide but emerges more than several feet above water level, to the delight of birds and other creatures. We saw several turtles in the water and many birds (mostly egrets) on the reef and in the air. During the approximately 90 minutes we were there, the reef went from just emerging from the water to over 10 feet above water level, with very substantial amounts of water draining from the edges of the reef.

As we were leaving, we noticed a zodiac boat flying the Lindblad/National Geographic flag. Sure enough, we pulled up alongside it and were treated to tropical drinks served from a punchbowl before our ride back to the Orion.

Dinner was again outside and comfortable; meals will probably be outside for the rest of the cruise. After dinner, they arranged to shut off the lights in one area of the ship and held a star party. We easily saw the Southern Cross, as expected, but also the Big Dipper, except it was pointing down to Polaris, which was below the horizon.

This article is part of a series about our recent trip to Indonesia and Australia. To see the introductory article in the series, click here.

Ethicswishing

[Robin Berjon]

This is somewhere between a call to action and a wake-up call:

"If you wish to be moral, you have to also pay attention to whether what you're doing actually works. And the best way to do that is to set up a forcing function for it: that's what checks and balances do."

"[...] Imagination isn't just a trite word to make your heart glow in pulp-class young-adult dystopia — imagination is the ability to depict justice, to see what we ought to aspire to. It is not a gift but rather a skill to hone."

There is an inherent question here about how you can create binding systems that enforce ethical standards - but also, how you can determine which ethical standards actually lead to the outcomes you want to establish.

I think there's a lot here that can be addressed through more distributed equity. As Robin says, "anywhere a powerful entity operates it is at risk of unethical behavior and therefore must be held in check by a control mechanism". One system of control - insufficient in itself but I think still necessary - is to ensure that power is spread among more people who are more connected to the effects of that power.

Distributing equity literally means handing over the means of production not just to workers but to those impacted by the work, reconnecting the decisions to their consequences. I don't know that you can have ethical tech that is motivated by centralized power. As Robin implies: so far, it hasn't worked.

Innovation in news is an oxymoron

If you’re waiting for permission to build something, or if you want to see how well something has worked for your peers or competitors before you implement it yourself, you will never, ever innovate.

If you’re waiting for permission to build something, or if you want to see how well something has worked for your peers or competitors before you implement it yourself, you will never, ever innovate.

That’s the trap that news media seems to be in: nobody wants to be the first to build something new. Perhaps it’s that times are so dire that experimentation feels like too much of a risk; perhaps it’s just an extension of top-down editorial culture. But there’s nothing out-there in media technology right now. I’m aware of some stuff coming down the pipe that I’m really excited about, but the most innovative thing that’s actually been shipped is getting people to subscribe by addicting them to puzzle games. Forgive me for thinking that’s not particularly exciting.

How can the news industry break out of its shell? How can it act like technology is something that it can shape, rather than something that just happens to it? How can it put value not just in product management but actual nuts-and-bolts technical innovation?

This feels existentially important.

Thinking about it. Working on it. I know I’m not alone.

I’m, uh, very bad at task management. I wouldn’t want to pathologize, but I’ve never been a particularly organized person. I’ve always aspired to be more organized, but I’ve never found a tool or a methodology that really works for me. They were either too rigid and opinionated or brought too much overhead: I had to remember to use them, and that was enough of a blocker to not.

Over the last two months, everything has — weirdly — changed.

Someone mentioned Todoist over on Threads, and although I had a vague memory of trying it years ago and it not working for me, I decided to install it again. Maybe it was just the right time for me now, or maybe the design has evolved, but it clicked pretty much immediately.

There are two things that make it great:

It’s everywhere I work It gets the hell out of my way

Whenever I need to remember to do something, I press a key combo — I’ve configured shift-command-T — and a modal lets me quickly tap it in using relatively natural language. That’s a similar workflow to what I’ve been doing with Alfred for years and years, so adding this new combo isn’t a giant feat of muscle memory.

Then, whenever I want to check what’s on my plate, I can bring up the app (desktop via ctrl-command-T, or phone), or click the toolbar icon in my browser to bring up the browser extension version. Because I spend most of my life in my browser, that’s particularly handy. It’s just always there.

I’ve found myself adding new tasks via modal while I’ve been in meetings, so I don’t forget to follow up. Or I’ll be in a Google Doc and add a task the same way. (There’s a way to automatically sync Google Tasks with Todoist, but I don’t use that — I’d rather have direct control over my task inbox.)

It’s made me more productive, more organized, and as a result, much less anxious. And I feel really good about it.

This post isn’t an ad, by the way. It’s just so rare that I really love a piece of software, so I thought I’d let you know.

Announcing our DjangoCon US 2024 Talks!

I'm speaking at DjangoCon in Durham, NC in September.

My accepted talk title was How to design and implement extensible software with plugins. Here's my abstract:

Plugins offer a powerful way to extend software packages. Tools that support a plugin architecture include WordPress, Jupyter, VS Code and pytest - each of which benefits from an enormous array of plugins adding all kinds of new features and expanded capabilities.

Adding plugin support to an open source project can greatly reduce the friction involved in attracting new contributors. Users can work independently and even package and publish their work without needing to directly coordinate with the project's core maintainers. As a maintainer this means you can wake up one morning and your software grew new features without you even having to review a pull request!

There's one catch: information on how to design and implement plugin support for a project is scarce.

I now have three major open source projects that support plugins, with over 200 plugins published across those projects. I'll talk about everything I've learned along the way: when and how to use plugins, how to design plugin hooks and how to ensure your plugin authors have as good an experience as possible.

I'm going to be talking about what I've learned integrating Pluggy with Datasette, LLM and sqlite-utils. I've been looking for an excuse to turn this knowledge into a talk for ages, very excited to get to do it at DjangoCon!

こんにちは、富士榮です。

昨日のアスリートの健康情報に続きプラスチック製品のリサイクルへの適用の事例の話です。


ご存知の通りEUでは諸々の排出量規制が厳しく、リサイクルも注力されている分野の一つです。

今週2024/7/18に既存のEcodesign Directive 2009/125/ECに変わる規制としてESPR(Ecodesign for Sustainable Products Regulation)が施行される予定ですが、その中には「Digital Product Passport」というものがあります。

どういうものか上記ESPRのサイトに記載があります。

The ESPR will introduce a Digital Product Passport (DPP), a digital identity card for products, components, and materials, which will store relevant information to support products’ sustainability, promote their circularity and strengthen legal compliance. 

This information will be accessible electronically, making it easier for consumers, manufacturers, and authorities to make more informed decisions related to sustainability, circularity and regulatory compliance. It will allow custom authorities to perform automatic checks on the existence and authenticity of the DPPs of imported products.

Information to be included in the DPP will be identified by the Commission, in close consultation with all relevant stakeholders, and will depend on the specific product in question. This information can include:

Product’s technical performance Materials and their origins Repair activities Recycling capabilities Lifecycle environmental impacts

ESPRは、製品、部品、原材料のデジタルIDカードであるデジタル製品パスポート(DPP)を導入します。DPPには、製品の持続可能性をサポートし、循環利用を促進し、法的コンプライアンスを強化するための関連情報が保存されます。

この情報は電子的にアクセスできるため、消費者、メーカー、当局が、持続可能性、循環型経済、法規制遵守に関するより情報に基づいた意思決定を容易にします。また、輸入製品のDPPの存在と真正性を、税関当局が自動的に確認できるようになります。

DPPに記載される情報は、欧州委員会がすべての関係者と緊密に協議した上で決定し、対象となる特定の製品によって異なります。この情報には、次のようなものが含まれます。

製品の技術的性能 材料とその原産地 修理活動 リサイクル能力 ライフサイクルにおける環境への影響

要するにモノを対象としたデジタルIDカードであるデジタル・プロダクト・パスポート(DPP)はリサイクルを含むモノのトレーサビリティを担保するためのものになるようです。

モノのIDということでGS1を思い出すと思いますが、やはり既にGS1ヨーロッパがリリースを出していますね。

https://gs1.eu/activities/digital-product-passport/

GS1ヨーロッパのページより
全ての製品のデジタルIDを付与することで環境への影響などを含めトレーサビリティを実現していくことで規制への対応をしていく、という話ですね。

既に一部の企業がAgro2Circularと連携してプラスチック製品のリサイクル分野でのDPP適用の実験なども行っているようです。

IOTAを使っているみたいです。




GS1標準スキーマをうまく使いつつデータ表現はVCみたいですね。



今後、日本においてもEUとの貿易を考えるとトレーサビリティ文脈でVCを利活用するケースも必要になってくるのかも知れませんね。

Lessons learned in 35 years of making software

Lots of great stuff in here from Jim Grey, with a strong focus on "soft skills" (I prefer the term "professional skills") around building relationships and making sure your contributions are visible.

This tip resonated with me in particular:

There is no substitute for working software in Production. I can’t believe now that I have been part of 18-month release projects. This was back in the bad old waterfall days, but even then it was possible to release a lot more frequently than that. The software we build is valuable. It builds the value of the company. When you hold it until it’s perfect, or everything you think it needs to be, you are holding back on building the company’s value. Find the fastest, shortest path to getting the smallest increment of the thing that will work into the customer’s hands. You can keep making it better from there.

And another tip on the subject of perfectionism:

When you deliver work you’re really proud of, you’ve almost certainly done too much and taken too long. I have a bit of a perfectionist streak. I want to do my work well and thoroughly. It took me a long time to learn that when I do that, it’s for me, not for the company. When I’ve reached 60-80% of the thing being as good as I want, I’ve probably done enough.

The Pragmatic Engineer

AI Tooling for Software Engineers in 2024: Reality Check (Part 1)

How do software engineers utilize GenAI tools in their software development workflow? We sidestep the hype, and look to the reality of tech professionals using LLMs for coding and other tasks.

In April last year we published The Productivity Impact of AI Coding Tools based on a survey of subscribers to this newsletter, about how new AI tools were helping developers with coding. Back then, ChatGPT and GitHub Copilot were the dominant tools and more were on the way during that time of experimentation. 

Based on readers’ feedback at the time, the article advised playing around with AI coding tools to find out what worked or not, and predicted: “AI coding tools will move the industry forward.”

Fast forward to 2024, and AI coding tools are more widespread than ever. GitHub Copilot has passed 1 million paying customers (safe to assume mostly developers,) and there’s been a surge in startups building AI software engineering tools, along with no shortage of hype.

A recent peak of the AI hype cycle saw some startups raise funding to “replace developers with AI engineers.” This publication’s take on that “mission” and similar ones is that they’re overheated marketing slogans in response to the popularity of GitHub Copilot, and aren’t the reality.

But how are engineers really using these tools in 2024? 

In order to sidestep the hype and tackle that question, we recently launched a new survey asking software engineers and engineering managers about your hands-on experience with AI tooling; which tools are being used this year, what parts of the development workflow are AI-augmented, what works well, and what doesn’t?

As far as we know, this is the biggest survey yet on how tech professionals are using AI tools, and this publication’s business model means we’re free from bias on the subject. The volume of responses was such that it’s taken a couple of months to compile the data, but today we present it!

We analyze input from subscribers to this newsletter and seek to offer a balanced, pragmatic, and detailed view of where LLM-powered development tooling is today.

This article covers:

Survey overview. Most of the data in this survey is from software engineers, with a roughly even split between people working with AI tools for less than 6 months, between 6-12 months, or for more than a year.

Popular software engineering AI tools. ChatGPT and GitHub Copilot remain the standouts in popularity. Google’s Gemini, Antrophic’s Claude, Jetbrains AI, Tab9, Cursor, Codeium, Cody, CodiumAI, and others follow.

AI-assisted software engineering workflows. Some of the most common workflows use Copilot in the IDE, chatting with AI bots instead of googling, AI-assisted debugging, and picking up unfamiliar languages and frameworks. There’s a long tail of helpful, innovative use cases.

The good. When AI tools work well, they’re a massive help in completing projects, increasing test coverage, and making experimentation easier.

The bad. Poor output, hallucinations, and devs over-trusting these tools, top the list of complaints.

What’s changed since last year? Surprisingly, not too much! Interactive rubber-ducking is more common, and teams are experimenting more with AI agents.

The bottom of this article could be cut off in some email clients. Read the full article uninterrupted, online.

1. Overview

A total of 211 tech professionals took part in the survey, an increase on the 175 responses to last year’s AI tooling questionnaire.

Positions: most respondents are individual contributors (circa 62%.) The remainder occupy various levels of engineering management:

Respondents’ job titles

We asked engineering leaders additional questions because these people are in a great position to see the impact of AI tooling on teams. We’ll cover the engineering leaderships’ views in a follow-up issue.

Experience: The lengths of respondents’ careers is segmented into five-year periods, up to 20+ years of experience (YOE) in the tech industry:

Respondents’ time spent in tech

Fun fact: one respondent had 60 years of professional development experience (!!) This developer is now semi-retired. His outlook on these tools – which he plans to use in the future – is positive, writing:

“I have seen many other technologies over the past 60 years that were touted as software developer eliminators. All of them failed to live up to the hype. This is a new age and AI looks like it may be a promising opportunity to push the boundaries in software design and development. Exciting time to be alive and see the future blossom before our eyes.”

Time spent using AI tools: again, a pretty even split between professionals who are new to using AI tools (6 months or less,) people who have used them for 6-12 months, and those who have done so for over a year.

How long respondents have been using AI tools for software development

Responses from people who don’t use AI tooling may seem a bit out of place in a survey about these tools, but we wanted to reach such developers and ask specific questions, in order to find out why some folks do not, will not, or cannot employ them. We’ll dive into this in a future article.

Size of company: a roughly even split in size from tiny businesses, all the way to mega-corporations. Companies with between 1-50 people are the majority.

Size of company worked at 2. Popular software engineering AI tools

ChatGPT and GitHub Copliot need little introduction as the market leaders in the software engineering sector. But exactly how popular are they, and which other tools do developers use?

The Tools

As just mentioned, ChatGPT and GitHub Copilot are heavily represented in the survey. The surprise was the degree of their popularity:

AI tools software developers use

The responses reveal that as many professionals are using both ChatGPT and GitHub Copilot as all other tools combined! Below is a breakdown of this “other” category; note, the next most popular tool, Google’s Gemini, has only 14% of the mentions garnered by GitHub Copilot:

Long tail of AI tools tried or used for software development

The difference in mindshare across respondents is significant, as becomes clear by visualizing all mentions together:

ChatGPT and GitHub Copilot dominate the AI tooling race

This chart lists all tools with at least two mentions in the survey. Those mentioned only once include Microsoft Teams AI, Amazon Q, Meta AI, Vercel’s v0.dev (UI generation from prompts,) Databricks AI assistant, Replit Ghostwriter, Ellipsis.dev (AI code reviews & bugfixes,) Mutable.ai (creating living documentation,) CodeRabbit AI (AI-powered code reviews,) StartCoder (code completion,) and Aider (AI pair programming in a terminal.) It’s great that so many tools are being tried out!

Favorite AI coding tools

We asked developers which tools are their favorites. 

GitHub Copilot and ChatGPT. As the charts show, these got the most mentions. Here’s a selection:

“Github Copilot chat is the real deal.” – engineer at a dev tools startup

“I use GitHub Copilot because it also has built-in chat” – Ruby on Rails developer at a quality control software vendor

“I use GitHub Coliplot for daily coding and ChatGPT 4 for complex, open-ended design discussions” – a data engineer

“GitHub Copilot autocomplete is nice [but] I’ve found its chat function chat useless. It’s the same with the “generate code from description” functionality. When I need a leetcode function such as “partition array X based on Y”, I like using chatGPT, because it works fine. But ChatGPT gets stuck on harder problems. For example, building complex typescript generics is too much to handle.” – engineer at a scaleup

“I only use Copilot currently. I did use the free ChatGPT, and every so often I come back to it for something specific.” – software engineer at a cybersecurity startup

GitHub Copilot Chat is mentioned quite a lot, mostly positively. A big plus is that it offers an alternative to opening a browser to use ChatGTP. Still, not everyone is blown away by what the market-leading AI can do, including a senior software engineer who’s saltiness is hard to miss:

“My favorite is GitHub Copilot. It’s the least bad of all the AI tools I have access to.”

Another respondent shares that their company evaluated 8 AI coding tools and settled on GitHub Copilot, which seems to have an advantage with companies buying department-wide licenses, and developers moving over to it from other tools:

“I started off with Tab9. After that, my company supplied me with a free GitHub Copilot option, so I started to use Copilot!” – Ruby on Rails developer at a quality control software vendor

Several respondents say ChatGPT is the only tool they use, and that they like it. A software engineer at an eSports company shares:

“ChatGPT is where I go if I want to reason about something and I don’t have colleagues around me available.”

Other tools earned honorable mentions as some devs’ favorite tools:

Claude – the Opus model – was mentioned several times as the best coding model. This was before the Claude 3.5 Sonnet model was released, which is much more proficient with coding tasks, according to the Anthropic team, who uses this model to develop their own product; meaning we can expect Claude’s popularity to increase.

Gemini. The most mentioned after ChatGPT and Copilot. Several respondents reckon Gemini is better for coding tasks than ChatGPT, and prefer to use it over OpenAI’s chatbot. One respondent says they alternate between Gemini and Claude to gauge which one works better for each use case.

Cursor also gets several mentions, with one respondent calling it a “game-changer.”

Codeium has several mentions as a favorite IDE, thanks to its code-aware autocomplete.

Perplexity and Phind are cited a few times as preferred search tools for software engineering-related topics.

Other tools: Aider (pair programming in the terminal), JetBrains AI, AWS CodeWhisperer and Rewatch (meeting notes) each had one mention

3. AI-assisted software engineering workflows

We asked respondents who have used AI tools for more than six months what an AI-assisted workflow looks like for them and/or their team. Some trends can be observed:

Tuesday, June 4, 2024

Bigge Island (pronounced “biggie”) is named for someone named Bigge although the island is big. It is the home for some more Gwion Gwion (ancient) and Wandjina (newer) rock art. Starting from the beach where we landed, we took a short hike to the art sites, with narration by our guides, particularly our indigenous guide, Goyma. I practiced some of the photography skills taught by our photo experts at some lectures earlier in the trip, with some success.

Mermaid Tree

After lunch (and some repositioning of the Orion), we landed at a different beach with a few boab trees. This included a huge and notable tree called the Mermaid Tree, around which a low platform had been built to protect its roots, much as has been done around some giant sequoia trees in California.

We then walked further along the trail to where a couple of “parade grounds” built by bower birds were located. The bower bird is very plain-looking, so to impress a potential mate, it creates a straw tunnel and decorates its approach with local materials. These aren’t nests, just ways to attract a mate.

Bower bird “parade grounds”

Returning to the ship, we found menus tucked into four doors across the hall, indicating additional COVID cases had been found. Dinner was moved outside to the aft deck, which was very comfortable and pleasant, but a lot of work for the staff since the galley is downstairs, necessitating a lot of shuttling back and forth.

I don’t recommend many business books .. in fact I don’t really recommend any, rather I recommend the authors, based on what I know, read and see them talking about. Christopher Lockhead is one such person and last week I recommended him again.

Email received this morning …

I tried buying Snow Leopard on Apple but only the audiobook is available.

I was more than a little surprised, but he’s not wrong. I even thought I’d sorted it ..by visiting the book on the 🔗 Category Pirates web site, see the link to ‘Apple Books’?

Yeah No. Apparently - click on that button and you are taken to Amazon.

Which is a good place to buy the hard copy - but this takes you to Kindle and sorry, no, not going to be doing that.

I wonder why no Apple Books? I was wondering whether it was the name - and its clash with an earlier OSX. But that was FIFTEEN YEARS AGO, and as mentioned above, the audio book is available.

Weird - right?

Fear not - I am on the case and if I get answers I will report back.

By the way - don’t try visiting that book page on a phone, or even the mini iPad - looks like there is something askew with the media settings for the site.

こんにちは、富士榮です。

もうすぐパリ五輪ですね。あまりスポーツに興味はありませんが。


Trusted Web推進協議会の実証事業でも色々とユースケースを集めて実証をしたわけですが、結局のところVerifiable Credentialsって何にでも使えてしまうところがあり、かつユースケースごとに微妙に要件が異なるわけで、結局何に使えるの??みたいにぼやけてしまいがちです。


これもその一つではありますが、Indicio社がアスリートの健康情報の保護にVerifiable Credentialsを使う、というユースケースについて書いています。

Indicio社のBlogより引用

https://indicio.tech/better-athlete-health-data-protection-through-verifiable-credentials/

アスリートがつけるウェアラブルデバイスから取得できるデータをVerifiable Credentialsを使って検証可能な状態でやり取りしましょう、という話で、以下の利点があると記載されています。

1. チーム、大学、医療提供者、およびこのデータを保存していたすべての人の責任が免除されます。

2. アスリートは情報を完全に管理できます。情報を見る必要がある関係者と情報を共有することはできますが、データの所有者に問い合わせる必要があり、所有者はデータのすべてを共有するか、特定の部分だけを共有するかを選択できます。

3. すべてのデータが 1 つの便利な場所にまとめられているため、要求されたときに情報のすべてのソースを追跡する必要がありません。

4. データはソースと同じくらい信頼できると想定できます。データに変更があった場合、分散型台帳に表示され、認証情報が「破られる」ため、ユーザーは発行元との二重チェックや検証に時間を費やす必要がありません。

5. データは、アスリートのエージェントなどの信頼できるパートナーと簡単に共有でき、必要に応じてアスリートに代わってデータを共有できます。


Trusted Webの実証事業でORPHEさんがやっておられたシューズの事例とかシミックさんがやっておられた治験データの事例に近いシナリオですね。


まぁ、データセキュリティに関する話なのでどの分野でも適用可能って言われたらそこまでですが、こうやって事例を増やしていくと見えてくるものもあると思うので、どんどんやっていけると良いですね。

RFC: PGXN Meta Spec v2

PGXN Meta Spec v2 represents a significant reworking of the original spec for PGXN distributions. It would very much benefit from feedback from Postgres extension and developers.

Two bits of news on the “PGXN v2” project.

PGXN RFCs: The Book

First, I’ve moved the RFC process (again, sorry) from PGXN Discussions, which were a bit fussy about Markdown formatting and don’t support inline comments, to the PGXN RFCs project, where use of pull requests on CommonMark Markdown documents address these issues. This process borrows heavily from the Rust RFCs project, right down to publishing accepted RFCs as a “book” site.

So I’d also like to introduce rfcs.pgxn.org, a.k.a., the PGXN RFCs Book.

It currently houses only one RFC: Meta Spec v1, dating from 2010. This document defines the structure of the META.json file required in archives published on PGXN.

But I expect many more RFCs to be drafted in the coming years, starting with draft RFC–2, the binary distribution RFC I POCed a few weeks ago. There has already been some great feedback in that pull request, in addition to the previous discussion. More eyes will make it even better.

PGXN Meta Spec v2 RFC

Last week I also iterated on the PGXN Metadata Sketch several times to produce draft RFC–3: Meta Spec v2. This represents a major reworking of the original spec in an attempt to meet the following goals:

Allow more comprehensive dependency specification, to enable packagers to identify and install system dependencies and dependencies from other packaging systems, like PyPI and CPAN Adopt more industry-standard formats like SPDX License Expressions and purls. Improve support multiple types of Postgres extensions, including apps, LOADable modules, background workers, and TLEs. Improve curation and evaluation via categories, badging, and additional download links.

There’s a lot here, but hope the result can better serve the community for the next decade, and enable lots of new services and features.

The proof will be in the application, so my next task is to start building the tooling to turn PGXN distributions into binary distributions. I expect experimentation will lead to additional iterations, but feel confident that the current state of both RFC–2 and RFC–3 is on the right track.

Monday, June 3, 2024

The Orion was repositioned overnight at our next destination on the Kimberley coast. Fortunately, the seas were relatively calm (as compared with the trip to and from Darwin), and we didn’t need to work as hard to walk around.

Our morning destination was the site of a World War II plane wreck, a C-53 that had gotten lost on a trip from Perth to Broome. They neglected to bring along a navigator. The plane ran out of fuel, tried to land on a mud flat, and skidded into the forest, losing one of its wings and an engine. Fortunately, they were rescued after several days, and everyone survived. The metal frame and skin of the plane are relatively intact, and we had an opportunity to walk around a bit and examine them.

While in the area, we walked through the woods and saw several things described in our preparatory lectures: a boab tree, a paperbark tree (essential to the Aboriginals for many uses), and a potentially quite old termite hill.

We walked back to the beach across the mud flat, examining large sandstone formations along the way.

The afternoon destination was Jar Island, a nearby island featuring ancient Gwion Gwion indigenous rock art. We were given three options for our short hike: “easy,” “moderate,” and “difficult,” with the more challenging routes giving us more to see. We chose the difficult route, which, other than requiring a little use of hands to ascend and descend some rocks, was not that challenging. The rock art was of uncertain (but very old) age and was painted on the sandstone at the three sites we visited.

Returning to the beach just as the sun was beginning to set, we were surprised by an impromptu beach party (cocktails and music) that the staff had set up. The party was a lot of fun, and we returned to the Orion just as it was getting dark.

Upon our return, our festive mood was quickly dispelled by an announcement from the ship’s doctor that three cases of COVID had been found on board the ship. Masks were distributed (but were voluntary), and arrangements were made to isolate the affected people in their cabins for a minimum of 24 hours and to bring their meals to them. I had noticed someone wearing a mask picking up breakfast early that morning and was suspicious that there was an outbreak on the ship. It soon became evident who the affected people were, as dinner menus appeared in the document holders on their cabin doors. Two of the cabins across the hall from ours were included.

去る7月10日に、デジタル庁から「DS-500 本人確認ガイドライン」に関する有識者会議による改定方針の令和5年度中間取りまとめが発表されました。全体として非常によくまとまった資料になっています。 中間取りまとめの概要は以下のようになっています。 中間取りまとめの概要 はじめに …

去る7月10日に、デジタル庁から「DS-500 本人確認ガイドライン」に関する有識者会議1による改定方針の令和5年度中間取りまとめが発表されました。全体として非常によくまとまった資料になっています。

中間取りまとめの概要は以下のようになっています。

中間取りまとめの概要 はじめに 本資料は令和5年度時点のガイドライン改定方針(案段階のものを含む)について今後の検討事項とともに中間的にとりまとめたものであり、改定方針として確定されたものではない。 最終的な改定方針については今後有識者意見を踏まえた見直しを行ったうえで、関係各所と調整の経て最終化することを予定している。 用語・表記について 本資料中の用語・表記は本資料内の定義であり、改定後の本人確認ガイドラインにおける用語を定義するものではない。 今後の検討事項 用語定義について “Validation”に対応する訳語の再検討 “Federation”に対応する訳語の再検討 “Biometric Comparison”に対応する訳語の再検討 現行ガイドラインの用語定義全般の見直し・最新化 本人確認ガイドライン改定方針(案)の全体像 主要な改定ポイント ガイドラインの適用対象と名称を変更 ミッション遂行などの基本的な考え方を解説 本人確認の枠組みを定義・解説 保証レベルと対策基準の一部を見直し リスク評価プロセスを全面的に見直し ガイドライン改定案の目次 はじめに 本人確認の枠組み 本人確認手法の検討方法 3.1 デジタル化を念頭に入れた対象手続の業務改革(BPR) 3.2 本人確認に係るリスクの特定 3.3 保証レベルの判定 3.4 本人確認手法の選択 3.5 検討結果の文書化 3.6 継続的な評価と改善 本人確認ガイドライン参考資料 参考資料1 本人確認に係るリスク評価ワークシート 参考資料2 保証レベルに対応する本人確認手法例等 本人確認ガイドラインの主要な改定ポイント ① ガイドラインの適用対象と名称を変更 「オンラインによる本人確認」から対面等も含める 「個人又は法人等の」から個人向け/法人向けで分冊化 「行政手続」から内部事務への将来的な拡大を検討 ② ミッション遂行などの基本的な考え方を解説 「1.5 基本的な考え方」を新設し、ミッション遂行、公平性、プライバシー、ユーザビリティなどを解説 ③ 本人確認の枠組みを定義・解説 身元確認、当人認証、認証連携の定義と解説を追加 認証連携を用いる場合の一般的なモデルの解説を追加 ④ 保証レベルと対策基準の一部を見直し NIST SP 800-63-4 におけるxALの改定を参考に、身元確認保証レベルと当人認証保証レベルの見直し ⑤ リスク評価プロセスを全面的に見直し 公平性やプライバシー等の観点も考慮した手法選択が行われるよう、リスク評価プロセス全体を見直し リスク評価を補助する参考資料を拡充 感想・講評

ご存知の方も多いと思いますが、わたしも有識者会議の末席を汚させていただいております。なので、これをまとめていただいた事務局の方々には本当に感謝しております。一方で、この会議で指摘した点の多くは資料中随時提示されている「今後の検討事項」に含まれています。読者の皆様におかれましては、これらのページをしっかりと読み込んでいただければと思います。

例えばP.19の「ウォレットモデル」ですが、「レジストリ」というものが入ってきて、その後ろにIDプロバイダがいる形になっています。このレジストリですが、よく分かりませんよね。実際には運用主体がいるものとなり、EUデジタルアイデンティティフレームワークでは、ウォレットプロバイダと呼ばれるもになります。ここに運用者がいることを意識することは非常に重要であり、ウォレットプロバイダはIDプロバイダであるという指摘も欧州でもなされるところです。そう考えると、IDプロバイダがウォレットプロバイダの後ろにあるような書き方は問題があることになります。ここでいう「IDプロバイダ」はEUデジタルアイデンティティフレームワークでは「属性アテステーションプロバイダ」(OpenID用語で言うとクレイムズ・プロバイダ)この辺りのことがP.23の「ウォレットモデル(仮称)に関する継続検討」に書いてあります。

Youtube Live 配信

前回Youtube Live配信を行ってから1月が経ってしまいました。やり方を忘れてしまいそうなので、この文書を飲みながら読む会を今週金曜23時あたりからやりたいと思います。

まさに選択的開示(笑)※拾い物です

本文に入っていきます。 最初のポイントは、「選択的情報開示の形態と種類、実現方法」についてです。
まず、選択的開示の方法として以下の3種類が挙げられています。 アトミック・クレデンシャル 選択的開示署名 ハッシュ値
アトミック・クレデンシャル 非常にシンプルな方法です。一つのクレデンシャルに一つのクレームのみを含むようにする手法です。 例えば、選択的開示可能なマイナンバーカードのクレデンシャルを作ろうと思ったら、名前・住所・生年月日・性別をそれぞれ別のクレデンシャルにしてしまって、必要に応じて提示するクレデンシャル自体を分ける、ということですね。 選択的開示署名 ネイティブに選択的開示をサポートしている署名形式を用いる手法です。CL署名とかBBS+なんかはこちらでしょうね。 ハッシュ値 全てのクレームを含むクレデンシャルを発行するものの値をハッシュ化する手法です。SD-JWTはこちらですね。論文中ではハッシュの方法論についても比較をしつつ解説していますので、こちらも参考になります。

他にもZKPについても語られており、ZKPとハッシュ値の組み合わせなど複合手法についても分析が行われています。

アトミック・クレデンシャルについては置いておくとして、選択的開示署名とハッシュ値の2点については方式が一覧化されています。
論文中に出てくる順番とは異なりますが、引用しておきます。

As Individual American citizens, we elect leaders, not committees. 

Functional literacy practitioners know the difference. 

Propaganda is a committee outcome.

Committee's are the dog of society, Individual people are the masters. 

Functional literacy doesn't get that twisted, ever. 

Freedom == Accountability  

There is work to do... I am committed to it.

Trump 2024 = Vote American Functional Literacy
















We're playing a game of American chess; people can say "I hate those Trump pieces" and they can say "I hate those DEI marxist pieces"... doesn't change the game... win the board. People are forgetting the purpose of the game... we're not collecting game pieces. DEI practices are a marxist attack vector on the game board and purpose for playing the game, plainly stated. 

Under CCP propaganda leadership it is openly stated, "America is not real, look at black women." The purpose for this statement is to manage Chinese people from believing that America is home to a civil society that functions better than the CCP. 

In America 2020-2024... black women are carrying the CCP propaganda water by enforcing DEI practices within bureaucratic enforcement and influence campaigns. Marketing communications companies, in coordination with W2/W4 political hires within the White House and US Government are producing propaganda, setting casting practices for advertising inventories, and expressing a bias in media generally. This is a funded and strategically coordinated work product pursuing a change to the fabric of American society. 

You are being hunted, as American citizens. 

Program; or be programmed. 

Reprogram; or be reprogrammed.


America is a diverse Nation. America is an inclusive Nation. Americans own equity, and the greatest inequity in the world is not knowing how to write an ownership contract for yourself. Functional American literacy is the most leveraged dream for a personal life where the liberty to pursue happiness is unfettered but for the size and nature of the dream being pursued. America invests a tremendous amount of resources improving itself, improving the lives of the people that pledge it allegiance. It matter not whether you bend a knee, because when you stand up for liberty, life and personal happiness, you stand for America. The solution is simple:

American people, Individuals all.

Sunday, June 2, 2024

Today, we begin our visit to the Kimberley, which is the trip’s theme.

The seas again became choppy overnight as we crossed the Joseph Bonaparte Gulf west of Darwin. To give us time to complete the trip from Darwin, we spent the morning listening to lectures on birds and the geology of the Kimberley and headed out to visit King George Falls in the afternoon.

After lunch, we boarded one of the Zodiac boats for King George Falls, which was about a 3-hour round-trip ride with some narration stops. The early part of the ride was a bit choppy, but it settled down as we approached the coast. At one of the stops early on, we were fortunate to see a rock wallaby, which is notoriously shy. We also saw a couple of peregrine falcons, which are said to be the fastest animals.

Rock Wallaby

The sides of the canyon on the way to the falls are red sandstone cliffs, with the different layers of sandstone visible. Our Zodiac boat was paired with another carrying Kirt, the geologist, and Goyma, our Indigenous guide, so we had detailed descriptions along the way.

The falls themselves were very picturesque. There was a fork in the canyon with falls on both sides. Our driver took the Zodiac boat right up to the falls, allowing those who wanted to be doused under them (Kenna and I didn’t, but Jan and Dave did). It was fun to watch.

The ride back to the Orion was speedier than the outgoing leg, but we stopped for a few bird sightings.

This article is part of a series about our recent trip to Indonesia and Australia. To see the introductory article in the series, click here.

論文中の選択的情報開示の概念の説明図より


Selective disclosure in digital credentials: A review https://www.sciencedirect.com/science/article/pii/S2405959524000614
Digital credentials represent digital versions of physical credentials. They are the cornerstone of digital identity on the Internet. In order to enhance privacy, different authors implement selective disclosure in digital credentials, allowing users to disclose only the claims or attributes they want. This paper gives an overview of the most influential articles for selective disclosure, a chronology of the evolution of the methods, and a list of strategies and approaches to the problem. We identify the categories of approaches and their advantages and disadvantages. In addition, we recognize research gaps and open challenges and provide potential future directions.

デジタル証明書は、物理的な証明書のデジタル版です。これらは、インターネット上のデジタルIDの基盤です。プライバシーを強化するために、さまざまな著者がデジタル証明書に選択的開示を導入し、ユーザーが開示したいクレームや属性のみを公開できるようにしています。本論文では、選択的開示に関する最も影響力のある論文の概要、手法の進化に関する年表、およびこの問題に対する戦略とアプローチの一覧を示します。また、アプローチのカテゴリーとその利点と欠点を特定します。さらに、研究におけるギャップや未解決の問題点を認識し、今後の方向性についても提案する。 


選択的開示(Selective Disclosure)がメインテーマではありますが、デジタルクレデンシャルそのものについても突っ込んだ言及がされていて面白いです。

Intro部分から飛ばしていて面白いです。

Unfortunately, this term is still used confusingly in different fields of computer science, computer security and cryptography because it is still evolving. A simple password is sometimes considered a digital credential; other times, a signed certificate is a digital credential.

 残念ながら、この用語はコンピュータサイエンス、コンピュータセキュリティ、暗号化のさまざまな分野において、まだ発展途上であるため、依然として混乱を招くように使用されています。単純なパスワードがデジタル認証と見なされることもあれば、署名付き証明書がデジタル認証と見なされることもあります。

クレデンシャルという言葉は確かにまだまだ混乱していますねぇ。
なお、本論文の中では、 選択的情報開示の形態と種類、実現方法 デジタルクレデンシャルの種類による採用される方法の違い ゼロ知識証明の利用の有無 ブロックチェーンの利用の有無 について論じています。
その前に、前提知識のセクションではこれまでの歴史や用語の解説がされているので、この部分だけでは読む価値は大いにありますので、この部分にフォーカスしていこうと思います。
ポイントはこのようなところかと思います。しかしU-ProveとIdemixとか懐かしい。 ブラインド署名プロトコル(David Chaumが1983年に発表、1985年に理論を実装)の発明がこの分野における第一歩であった このプロトコルによりユーザは匿名性を維持しながら証明書の所有を証明したり、欲しい情報を開示することができる この理論をベースにリンカビリティに焦点を当てたのがIvan Bjerre DamgardとStefan Brandsであり、後にMicrosoftが買収するU-Proveの基礎となるBrandsブラインド署名となった(秘密鍵証明書スキームを盛り込んで理論化した) CamenishとLysyanskayaは匿名クレデンシャルためのプロトコル(CL署名)を発表した。その論文の中では匿名クレデンシャルの特徴として以下を定義、達成した 匿名性:各ユーザはシステム内で匿名である 追跡不可能性:ユーザによるクレデンシャルの利用を追跡できない 偽造不可能性:クレデンシャルの偽造ができない リンク不可能性:同じクレデンシャルを複数回利用することによってリンク可能になってはならない 他にも追加の特徴として以下を挙げた 譲渡不可 選択的開示 取り消し 悪意あるユーザの識別 これらのスキームはIBMのIdentity Mixer(Idemix)の基本的な構造となっている Dan Boneh、Ben Lynn、Hovav Shachamはバイリニア対と楕円曲線で構築されたグループ署名であるBLS署名を開発し、C. Gentryとともに複数のメッセージに対して複数の公開鍵で生成された複数の署名を1つの署名に集約するソリューションを提案した。この署名形式はイーサリアム・ブロックチェーンで採用されている Dan Boneh、Xavier Boyen、Hovav Shachamはその後も匿名クレデンシャルの研究を続け、ペアリング・ベースの楕円曲線暗号をベースに構築されるグループ署名(BBS署名)を開発した。これはその後の改良を経てBBS+署名スキームと呼ばれている その後、これらの理論はU-ProveやIdemixにより実装が進み進化していく U-ProveはStefan Brandsが設計したブラインド署名をベースに実装され、Brandsによって設立されたCredentica社によって開発が進んだが、2008年にMicrosoftに買収される(Microsoftに買収された後、Preview版をもらって検証していたころが懐かしいです) 一方でIBMのIdemixは2002年に発表されたCL署名スキームに基づく匿名クレデンシャルシステムである U-ProveもIdemixもEUの資金提供を受けたABC4Trust(Attribute Based Credential for Trust)2010-2015に繋がった このプロジェクトは異なるプライバシーABCシステムをフェデレーションして相互接続することを目的としており、ABCシステムの特徴は以下の通り定義された プライバシーABCはエンティティに関する追加情報を開示することなくエンティティに関する異なる属性を選択的に認証する プライバシーABCは保有者が必要最低限の情報を公開し証明することが可能である これらの特徴をU-ProveおよびIdemixにより実現されたが、これ以外にも離散対数コミットメントを用いたHM12スキームや、オープンソースのYiviアプリ(IRMA/I Reveal My Attributes)も登場した(YiviアプリはIdemix ABCスキームに基づいている) ブロックチェーン技術に進歩に伴い、Linux FoundationはHyperledgerを設立、IBMとHyperledge Fabricプロジェクトを共同で設立し、Idemixをインポートした EvernymとSovrin Foundationは自己主権型アイデンティティプラットフォームの構築を目指すプロジェクトをLinux Foundationの寄付し、Hyperledger Indyが誕生する Hyperledger Indyにおける最初の匿名クレデンシャルの実装はCL署名に、次の実装はBBS+署名に基づいている 一方でVerifiable CredentialsについてはBBS+署名、CL署名、ハッシュマークルツリー、SD-JWT、AnonCredsなど匿名化に向けたいくつかのソリューションが提案されている状態である
ここまで読んだだけでもすごい情報量ですね。 非常に面白く読ませてもらっています。
続きはまた。

なお、顔マッチング(Facecheck)機能はPreviewの時点でこのブログでも取り上げています。 https://idmlab.eidentity.jp/2024/02/entra-verified-idmicrosoft-authenticator.html
ちなみにお値段ですがチェック1回あたり0.25ドルです。まぁまぁしますね。 https://learn.microsoft.com/en-us/entra/verified-id/verified-id-pricing

とりあえず使ってみましょう。 いつものポータルに顔チェックのアドオンが現れているので有効化します。

有効にするとサブスクリプションとのリンクの設定を求められます。


とりあえずこれで資格情報を提示する際にFacecheckが行われるようになります。 Verifierを使った実際の動作確認は改めてやってみようと思います。

「なんでアクセストークンがいるの?パスワードを保存すれば良いのではないの?」というパワーワードを聞いたので説明してみる

ID本の読者の一人から、「なんでアクセストークンがいるの?パスワードを保存すれば良いのではないの?」というパワーワードを聞いた。そうか、そういえば、そういうベーシックなことを説明していなかったな。というわけで、改定の機会があったら加筆するとして、とりあえずブログにしておきます。

OAuthと2つのトークン

OAuthの登場者には、

保護対象リソース (Protected Resource):アクセス制御がされるべきリソース リソース管理者 (Resource Owner) :保護対象リソースに対するアクセスを決定することができる人または組織 認可サーバ (Authorization Server):リソース管理者の指示に従って、クライアントにトークン(切符)を発行するソフトウェア クライアント (Client):リソース管理者の許可のもとに保護対象リソースにアクセスして何らかの処理を行うソフトウェア ユーザ・エージェント(User-agent):ブラウザなどユーザであるリソース管理者がシステムと対話するのに使うソフトウェア

の5つのアクターがいます。

OAuthフレームワークは、リソース管理者 がクライアントに出した、リソースアクセスに関する許可 (Grant) を、保存可能な2種類の「トークン(切符)」として認可サーバが発行し、それを受け取ったクライアントがそれらを保管、そのうちの一つの「アクセストークン」を使ってリソースにアクセスする方法を取りまとめたフレームワーク(枠組み)です。IETFという標準化団体が定める文書、RFC6749とRFC6750によって基本が定められています。

2種類のトークンとは、アクセストークンとリフレッシュトークンです。クライアントはこれらを保存して後から使います。

アクセストークンは、リソースアクセスのために使われるトークンです。必要な最低限の権限を表しています。使用先=受取者はリソースです。複数のリソースに対して使われるのと、通常リソースの保護レベルは認可サーバの保護レベルより低いため、漏洩のリスクがそれなりにあります。また、通常持参人式トークン(Bearer Token)ですから、盗まれたものも使えてしまいます。このリスクを下げるために、短期間しか有効でなくすることが多いです。

もう一つのトークン=リフレッシュトークンは、認可サーバに対してしか使われません(使用先=認可サーバ)。なので、盗まれる可能性は低いです。しかも、使用者制限トークン(Sender Constrained Token)ですので、盗まれても、クライアントクレデンシャルも一緒に盗まれないと使えませんので、盗難・使用リスクがアクセストークンに比べて著しく低いのが特徴です。そのため、長期間有効にするのが一般的です。クライアントは、このリフレッシュトークンを使って、新しいアクセストークンを取得することができます。アクセストークンを洗い替える(refreshする)から、リフレッシュトークンと言います。

この辺りについてアニメーションも使って説明した動画は以下に作ってあるのでご覧ください。

パスワード保存じゃダメなの?

さて、冒頭の質問についてです。どうも、こんな面倒くさいことやらなくても、クライアント(ネットワーク上にある共有クライアント)はそれぞれのリソース管理者のユーザ名とパスワードを保管しておけば、リソースにはアクセスできるじゃないか。OAuthなんかいらないじゃないか、という話のようです。(このリソースは、ユーザ名とパスワードを受け取ってユーザを受け入れるwebインターフェイスも持っています)

ダメな理由はいくつも挙げることができます。

パスワードを保管するやり方は、リソース管理者の持つ全権限をクライアントに与えることになる。クライアントに限定的な権限移譲をすることができない。(最小アクセス権限の原則違反) リソースからすると、アクセスしに来ているのがリソース管理者なのか、クライアントなのかわからない。その為、有効にリスク管理をすることができなくなる。(なりすまし禁止原則違反) リソースを高度認証(パスキーなど)で守ることができなくなる。(適切な認証強度原則違反) ネットワーク上で可逆な形で複数のリソース管理者のパスワードを保管しなければならず、漏洩リスクが看過できない。(パスワードの可逆保管禁止原則違反)などなど

もういいですよね?パスワード保存ではダメなんです。

マックで二人のJKが話してた版

なんか硬いなーというので、Claude.ai に「マックで二人のJKが話してた版」を作ってもらったのでよろしくご査収ください。

まい: ねぇねぇ、さっきネットで見たんだけどさ、ヤバくない?

ゆか: なになに?どんな話?

まい: なんか、WebアプリがOAuth使う代わりにみんなのパスワード保存しちゃえば、サイトで何でもできるし作るのも簡単だし便利じゃね?って。

ゆか: えぇ!?それってマジやばくない?

まい: そうそう!でもさ、それって全然ダメなんだって。

ゆか: え、なんで?便利そうじゃん。

まい: いやいや、理由がいっぱいあんだって。まず、パスワード預けちゃうと、そのWebアプリに全部お任せみたいになっちゃうんだって。

ゆか: うわ、それヤバすぎ!制限とかつけられないじゃん。

まい: そうそう!んで、サイトからしたら、誰がアクセスしてきてんのかわかんなくなるんだって。

ゆか: マジで?本人なのかWebアプリなのか、めっちゃ混乱しそう。

まい: しかも、パスキーとかの超かっこいい認証方法も使えなくなっちゃうんだって。

ゆか: えー、それダサすぎない?

まい: でしょ?最後に一番やばいのが、ネット上にみんなのパスワードがバレちゃう形で保存されちゃうんだって。

ゆか: うわぁ、それ超怖い!もう絶対ダメじゃん。

まい: そうそう!だからWebアプリにパスワード保存とか、マジありえないんだって!

ゆか: なるほど〜。ちゃんとOAuthした方がいいってことね。勉強になった〜!

Making Bubbles: Three Stages of Identity

One of the key aspects to the bubbles model for federated identity systems is the fact that within the bubble, the account for each user is fully authoritative for that space. But since bubbles don’t exist in a vacuum, that same person probably has accounts that exist in other bubbles. In fact, the attributes in their account probably came from somewhere else to begin with. And of course, our bubb

One of the key aspects to the bubbles model for federated identity systems is the fact that within the bubble, the account for each user is fully authoritative for that space. But since bubbles don’t exist in a vacuum, that same person probably has accounts that exist in other bubbles. In fact, the attributes in their account probably came from somewhere else to begin with. And of course, our bubble can in turn act as a source for another system downstream.

Three stages of an identity in bubbles

With that model in mind, from the perspective of our bubble, we’ve got three distinct identity processing systems that all need to come together to make things work: the local identity management system for our bubble, something to process inbound accounts, and something to package accounts up for outbound transmission to somewhere else.

The Local Bubble

Within the bubble itself, we are using a cohesive IdAM system and are almost certainly using federation technology to connect out to a set of RP’s within the bubble. All of these systems can look towards one authoritative IdP within the bubble for the source of all account information.

Inside the bubble, we have tons of freedom for how we want to connect our users to our systems. While we probably want to use current best-of-class technologies like OpenID Connect and passkeys, we only really need to be compatible internally, using whatever makes the most sense for our environment.

The important thing here is that each user has an account that is accessible within the bubble at all times, and is not dependent on reaching out to anything outside the bubble for local authentication.

Inbound Processing

Most of the users in a bubble probably came from somewhere. If we onboard an account from an external system, it means that we’re creating an account based on a set of attributes from a known source. These attributes can come in with an assertion, credential, certificate, API call, or some other technology. The important thing, for us, is that we can now tie these attributes to a known account, and we can cache the attributes as we received them. A lot of these are going to be immensely useful — we won’t have to have every user type in all their attributes every time they connect into a new bubble.

But it’s not enough that we’re just making a cached copy. In many cases, we’ll want to override or update these attributes locally, but we don’t necessarily want to lose the data from the source when we do that override. After all, we don’t control the data source, and we want to know where all of our information came from.

We can use an overlay style data structure that lets us keep both updated data and the source data at the same time. Let’s say, for instance, that Patty O’Sullivan gets an account onboarded into the system, but it turns out that everyone inside the bubble just calls her Sully. We can create a local value that overrides the official value, but the official value doesn’t go away: it’s still sitting in its own structure. If we don’t have an override, when we look up an attribute we can follow a pointer to an upstream source and get it directly without having to copy it.

The approach also allows us to very efficiently take care of cases where we don’t have a need for referencing an attribute that was handed to us, or that we need to create a brand new attribute that doesn’t exist at the source. And in fact, this pattern can be applied up the chain, since our source might have gotten its information from somewhere else in the first place.

And we can just keep copying this pattern, even pointing at multiple sources at the same time. We can optimize this graph structure for both storage size and lookup efficiency, but more importantly it allows us to keep the data sources separate from each other in a meaningful fashion. We can tell where we’re getting each attribute value from, and we can differentiate between local updates and data copied from elsewhere.

This also means that we can put restrictions on data from different layers. For example, maybe we want a policy that needs an update on a cached value every so often. Or if I’m doing a local override of an important attribute, like one that gets used in security decision making, then I need to check that the override is still valid after a certain timeout. This can avoid a class of configuration errors that we see in the field, where something gets changed in order to solve an immediate problem, but never gets changed back when things de-escalate.

Outbound Packaging

And of course, we also want our bubble to be able to act as the source for some downstream receivers as well. In order to do that, we need to be able to package up our accounts and assert them outbound.

But wait a moment — isn’t that the same exact thing we’re doing inside of the bubble for our apps? Aren’t we already going through a federation process to connect on the inside? Shouldn’t we just use that same IdP again, since it’s already set up and has all the same accounts?

While it would be possible to re-use the same component, it makes more sense to have a dedicated IdP that only speaks to external receivers. This separation allows us to deliberately control which information we share and with whom, and without it being conflated with local policy, changes, overrides, and other concerns. When we’re talking to an external receiver, we likely want to give a very specific view of an account in this context, especially considering that we want to minimize the transmission of sensitive data across boundaries.

Stacking the Three Pieces Together

Each identity system we’ve talked about here has a distinct role to play. In this way, the three parts of a bubble system — inbound, local, and outbound — can work together to create a cohesive path for an account, its attributes, and the person who’s using it.

Fully-Specified Algorithms Specification Addressing Working Group Last Call Comments

Orie Steele and I have updated the “Fully-Specified Algorithms for JOSE and COSE” specification to incorporate working group last call (WGLC) feedback. Thanks to all who took the time to comment on the draft. Your feedback was exceptionally actionable and helped to substantially improve the specification. Responses to each WGLC comment thread were sent on […]

Orie Steele and I have updated the “Fully-Specified Algorithms for JOSE and COSE” specification to incorporate working group last call (WGLC) feedback. Thanks to all who took the time to comment on the draft. Your feedback was exceptionally actionable and helped to substantially improve the specification. Responses to each WGLC comment thread were sent on the IETF JOSE working group mailing list.

The updated draft attempts to discuss the full range of the problems created by polymorphic algorithm identifiers. Guided by working group feedback, it strikes an engineering balance between which of these problems to fix immediately in the specification and which to describe how future specifications can fix later as the need arises.

I look forward to discussing next steps for the specification at IETF 120 in Vancouver.

The specification is available at:

The Pulse #100: Large AI Players Snap Up Smaller Ones

Also: why dev tools ask for work email, the “Big Stay” phenomenon, ChatGPT usage stalls then recovers, and more.

The Pulse is a series covering insights, patterns, and trends within Big Tech and startups. Notice an interesting event or trend? Send me a message. This issue is a minor landmark for the series: the centenary (100th) edition. Thank you to all subscribers and readers for making this possible!

Today, we cover:

Industry pulse. Tone-deaf job cuts at Intuit; GenAI creating more carbon pollution by cloud providers, Big Tech no longer wants to be on OpenAI’s board, late-stage valuations rebound, and more.

Large AI players snap up smaller ones. More AI startups are selling themselves to the larger players. Consolidation in a sector usually means rapid growth has finished, but these outcomes often benefit startups.

Why do some SaaS tools need work emails? Dev tools are considered business-to-business (B2B) products in how they are sold: and these companies often don’t want to deal with people who do not currently work at a company.

“Big Stay” in all sectors. Employees everywhere are more reluctant to change jobs across the US, not just in tech.

ChatGPT usage stalled, but is growing again. After a year of virtually unchanged web usage, ChatGPT’s launch of its new model and voice modalities seems to have doubled interest and usage.

1. Industry pulse Intuit’s tone-deaf job cuts

Intuit is a large financial software corporation, best known for Turbotax, a market leading tax filing software in the US, and Quickbooks, a popular accounting software suite. The company made waves in 2021 when it acquired the email service Mailchimp for an eye-popping $12B. This deal made huge waves because Mailchimp was fully bootstrapped, and the acquisition remains the largest bootstrapped company purchase to date. The cultures of Mailchimp and Intuit seemed to clash at the time, in large part due to Intuit ending Mailchimp’s full-remote work model in 2022.

Intuit is now back in the news, with the announcement of a fresh round of layoffs at the software maker. Yesterday (10 July) the company announced letting go 10% of staff – 1,800 people, while also sharing that they’re hiring another 1,800 people to build GenAI products and features; mostly engineers, product, sales, and marketing people.

So Intuit is firing exactly as many people as they are hiring, which will surely be a blow to anybody being laid off. Still, given so many businesses are currently rushing to build AI-powered functionality, it’s not a total shock. What makes it tone deaf is an email from Intuit’s CEO, explaining the layoffs and the strategy shift behind them. (Emphasis mine):

“Taking care of our people

It is never easy to say goodbye to our colleagues and friends and we are committed to treating everyone who has been impacted by these changes with the compassion and respect they deserve. 

Let me first start with who is impacted by these decisions:

We’ve significantly raised the bar on our expectations of employee performance, resulting in approximately 1,050 employees leaving the company who are not meeting expectations and who we believe will be more successful outside of Intuit.“

With a single sentence, Intuit calls the people losing their jobs “low performers” in full view of the public, in a message labeled “taking care of our people.” If that’s what taking care of people looks like at Intuit, then I fear for its current employees!

This fully public message is incredible for a few reasons:

It could harm affected folks’ employment prospects because most of them (read, all) have been publicly labeled “low performers” by their ex-employer

What does Intuit’s CEO, Sasan Goodarzi gain from it? It makes Intuit’s leadership team look incompetent for having employed so many people who are apparently “not meeting expectations” (his words.) Shareholders could argue this was working against shareholders’ interest.

Intuit claims 1,050 people did not meet performance expectations, but it’s still paying them all very generous severance of 16 weeks pay, plus two weeks for every year served, plus bonuses paid. Actual low performers rarely get such a package.

Basically, the statement seems incoherent and baseless upon close inspection. By comparison, Meta let go of around 25% of staff in 6 months, but didn’t feel the need to say publicly that a single one of them was not meeting expectations.

Anyone who has conducted layoffs knows that the group affected contains a mix of low performers, and those in the wrong team or organization at the wrong time. Companies do not comment on who is who, so hiring managers give people the benefit of the doubt and the chance of a fresh start elsewhere. This clumsy statement by Intuit’s CEO strips everyone of the benefit of that doubt, tarring them all as incompetent. Who’s being incompetent here?

As a reminder, we previously did a deep dive on how to execute layoffs humanely. Intuit seems to have used several of the practices mentioned in the article, like generous severance, additional insurance, and job placement services. It makes the needless lack of compassion in the CEO’s email stick out even more.

Is GenAI creating more carbon pollution by cloud providers?

Hilf jetzt mit die Chatkontrolle zu stoppen!

Die Chatkontrolle ist wieder auf der Tagesordnung der Regierungen der EU. Sie wollen ihren bisherigen „Fortschritt“ am 10./11. Oktober besprechen und die Chatkontrolle am 12./13. Dezember beschließen. Im Juni …

Die Chatkontrolle ist wieder auf der Tagesordnung der Regierungen der EU. Sie wollen ihren bisherigen „Fortschritt“ am 10./11. Oktober besprechen und die Chatkontrolle am 12./13. Dezember beschließen.

Im Juni war es uns gelungen die beispiellosen Pläne mit einer extrem knappen „Sperrminorität“ der EU Regierungen aufzuhalten: Die Befürworter der Chatkontrolle erreichten damals 63,7% der 65%-Mehrheit, die im Rat der EU für eine qualifizierte Mehrheit erforderlich ist.

Zahlreiche Regierungen wie Frankreich, die sich früher gegen die Pläne gestellt hatten, haben ihren Widerstand bereits aufgegeben. Viele Regierungen wie die deutsche Bundesregierung, die immer noch kritisch zum Vorschlag stehen, melden nur noch geringfügigen Änderungsbedarf an (z.B. eine Ausnahme für Ende-zu-Ende-Verschlüsselung ), womit unsere private Kommunikation von den meisten Diensten immer noch massenhaft durchsucht und geleaked würde. Darum besteht jetzt aktuell die konkrete Gefahr, dass die benötigte Mehrheit für die massenhafte Durchleuchtung privater Kommunikation während der ungarischen Ratspräsidentschaft erreicht wird (Ungarn unterstützt den Vorschlag).

Deshalb müssen wir uns alle engagieren, unsere Stimmen gegenüber unseren Regierungen erheben und die Bevölkerung aufklären.

Regierungen, welche den Chatkontrolle-Vorschlag bisher unterstützt haben, müssen überzeugt werden ihre Position zu ändern Sich kritisch verhaltende Regierungen müssen dazu gebracht werden, umfassende und nicht nur kleine Änderungen am Vorschlag zu fordern, so wie sie das Europäische Parlament fordert.

Dieser Blogartikel erklärt verschiedene Möglichkeiten, wie du aktiv werden kannst. Jede*r kann sich einbringen. Um uns erfolgreich gegen die Chatkontrolle zu wehren, müssen wir uns alle engagieren!

Auf dieser Karte (die du gerne online teilen kannst!) kannst du die Positionen der EU-Mitgliedstaaten zur Chatkontrolle Stand Juni sehen. Die Länder sind außerdem in der Tabelle unten aufgeführt.

Ist deine Regierung für die Chatkontrolle?
→ Verlange eine Erklärung und dass die Regierung ihren Kurs ändert.

Enthält sich deine Regierung?
→ Frage sie nach den Gründen und fordere, dass sie sich in Zukunft entschieden gegen die Chatkontrolle einsetzt.

Ist deine Regierung gegen die Chatkontrolle?
→ Prima, aber schau genaue hin: Einige Regierungen, wie z. B. die deutsche Bundesregierung, lehnen nur das Scannen verschlüsselter Kommunikation ab, sind aber mit dem anlasslosen Scannen anderer privater Kommunikation einverstanden, oder mit dem Ende anonymer Kommunikation durch verpflichtende Alterskontrollen, oder mit der Einführung eines Mindestalters für vermeintlich „riskante“ Messenger und Apps zur Kommunikation. Auch müssen Regierungen jetzt ihren Einfluss im Rat der EU besser geltend machen und sich mit anderen kritischen Staaten auf gemeinsame Forderungen verständigen und den Vorschlag damit grundliegend überarbeiten. Wenn diese Änderungen nicht umgesetzt werden, sollten die Regierungen von der Europäischen Kommission eine Rücknahme des Chatkontrolle-Vorschlags verlangen.

Das kannst du tun

Es gibt Maßnahmen, die du sofort und kurzfristig ergreifen kannst, und solche, die mehr Vorbereitung erfordern. Für den Anfang:

Bitte deine Regierung, von der Europäischen Kommission die Rücknahme des Vorschlags zur Chatkontrolle zu fordern. Weise sie auf einen gemeinsamen Brief hin, der gerade von Kinderrechts- und Digitalrechtsgruppen aus ganz Europa veröffentlicht wurde. Klicke hier, um den Brief und weitere Informationen zu finden. Aus Deutschland? Fordere die Bundesregierung dazu auf, die Chatkontrolle konsequent und vollständig abzulehnen und den eigenen Einfluss im Rat der EU zum Schutz unserer Grundrechte geltend zu machen. Aus einem anderen Land als Deutschland? Überprüfe das Abstimmungsverhalten deiner Regierung (siehe oben) und bitte sie um eine Begründung, falls sie für oder gegen die Chatkontrolle gestimmt hat. Sage ihnen, dass du als Bürger*in willst, dass sie den Vorschlag ablehnen, dass die Chatkontrolle von vielen Expert*innen kritisiert wird und dass keiner der bisher im Rat der EU vorgelegten Vorschläge akzeptabel ist. Fordere sie auf, die Privatsphäre deiner Kommunikation und deine IT-Sicherheit zu schützen. Teile diesen Aufruf zum Handeln online.

Die besten Anlaufstellen in deiner Regierung sind in der Regel das Innenministerium (federführend) und Ministerien für Justiz und für Digitalisierung / Telekommunikation / Wirtschaft. Außerdem gibt es für jedes Land eine Ständige Vertretung bei den EU-Institutionen. Die Kontaktdaten der Ständigen Vertretungen findest du, indem du hier klickst.

Es kann auch sehr helfen sich an die Abgeordneten in den nationalen Parlamenten zu wenden, da sie das Stimmverhalten ihres Landes festlegen können. Sprich deine politischen Vertreter*innen an. Ob es sich um die neu gewählten Abgeordneten des Europäischen Parlaments oder um lokale Gruppen der politischen Parteien handelt: Sie alle sollten erfahren, worum es bei der Chatkontrolle geht und dass du von der Politik erwartest, deine Grundrechte gegen den Chatkontrolle-Vorschlag zu verteidigen!

Tipp: Wenn du mit Politiker*innen in Kontakt treten willst, solltest du möglichst einen echten Brief schreiben, im Büro anrufen oder zu einer lokalen Parteiveranstaltung oder zu Öffnungszeiten des Büros gehen und dort ein persönliches Gespräch führen. Das hat eine noch größere Wirkung als eine E-Mail. Die Kontaktdaten findest du in der Regel auf den Websites der Politiker*innen und der Ortsgruppen der Parteien. Denk daran, dass du deinen Standpunkt entschlossen vertreten, dabei aber auch höflich bleiben solltest, da sie dir sonst nicht zuhören werden.

Hier findest du eine Argumentationshilfe zur Chatkontrolle. Und nachfolgend mehrere Erklärungen, warum die bisher von den Regierungen vorgesehenen Änderungen nicht ausreichen, um den Gefahren der Chatkontrolle entgegenzuwirken: von uns, von EDRi, von CDT.

Während wir den Kampf gegen die Chatkontrolle fortführen, müssen wir den Widerstand noch weiter ausbauen:

Erklär deinen Bekannten, warum das ein wichtiges Thema ist. Dieses kurze Video, das in alle europäische Sprachen übersetzt wurde, kann ein hilfreicher Anfang sein. Du kannst es frei nutzen und teilen! Auch verfügbar auf YouTube und PeerTube. Aktiv zu werden funktioniert besser und ist motivierender, wenn man zusammenarbeitet. Versuche also, Verbündete zu finden und Allianzen zu schmieden. Ob in einem lokalen Hackspace oder in einem Sportverein: Deine lokale Aktionsgruppe gegen Chatkontrolle kann überall an den Start gehen. Dann könnt ihr kreativ werden und überlegen, welche Art von Aktion am besten zu euch passt.

Werde jetzt aktiv. Der Widerstand gegen die Chatkontrolle sind wir alle!

Hoch kontrovers, intransparent und kaum hinterfragt: Zur Zeit bereiten Kommission und Rat der Europäischen Union ein neues, EU-weites Überwachungspaket vor. Der #EuGoingDark-Plan umfasst unter anderem die Wiedereinführung und Ausweitung der Vorratsdatenspeicherung von Kommunikationsdaten der Bürgerinnen und Bürger sowie konkrete Vorschläge zur Aushebelung der sicheren Verschlüsselung von Daten auf allen vernetzten Geräten von Autos bis Smartphone, Daten bei Diensteanbietern und Daten während der Übertragung.

„Journalistisch und politisch ist der #EuGoingDark-Plan nach wie vor ein blinder Fleck, obwohl eindeutige Dokumente vorliegen und das Ausmaß der geplanten Maßnahmen erschreckend ist“, sagt der Europaabgeordenete der Piratenpartei Dr. Patrick Breyer.

Offene Fragen

Wer hat an den Treffen der EuGoingDark-Arbeitsgruppe und ihrer Unter-Arbeitsgruppen teilgenommen? Teilnehmerlisten sind nach wie vor Verschlusssache . Mullvad VPN hat berichtet, dass, mindestens ein ehemaliger US-Geheimdienstler teilgenommen hat. Warum wurden digitale Grundrechte-NGOs wie etwa EDRi auch auf Nachfrage nicht zu den Treffen der Arbeitsgruppe eingeladen obwohl diese laut Website eine „kollaborative und integrative Plattform für Interessengruppen“ ist? Wurden die Transparenzregeln der Gruppe mitten im Arbeitsprozess heimlich ausgetauscht und dabei massiv eingeschränkt? Die schriftliche Anfrage von Dr. Patrick Breyer dazu ist nach wie vor unbeantwortet. Warum sind die Arbeitsgruppe und ihre Unter-Arbeitsgruppen nicht im Register für Expertengruppen und ähnliche Foren (z. B. Beratungsgremien) der Kommission eingetragen, wodurch ihre Transparenz stark eingeschränkt ist? Wie bewerten die neuen, direkt und indirekt mit den betroffenen Themen befassten Kommissarinnen und Kommissare der EU-Kommission, die Europäischen Bürgerbeauftragte, die Datenschutzbeauftragten der EU und der Mitgliedsländer, IT-Sicherheitsexperten, Verbraucherschutzverbände und andere die Arbeitsweise und Pläne der #EuGoingDark-Gruppe?

DARPA enabled the creation of TCP/IP as means of overcoming limitations of networks communicating with other networks, to yield an "inter-network" outcome of communication portability, on battlefields and beyond. This is the origin of ARPAnet.

NSF helped commercialize ARPAnet by formation of Network Solutions, Inc and deployment of ICANN, ARIN, to serve TCP/IP domain registry to public. This public internet of IP addresses and domain names was released in 1996 for public consumption.

Vint Cerf, co-creator of TCP/IP at DARPA, via private communication with author while at MCI, in question about why TCP/IP deployment via domain registries prioritized a renter model of cost support rather than an owner model, answered: "that was considered in 1976 and discarded".

As a result of this discarded consideration, and subsequent growth of TCP/IP use in American/Global civil societies, the original intent of DARPA within the engineering design choices made in 1976, prior and after, end "users" of this innovative technology have received a relationship structure via this infrastructure giving meaning and utility to data at scale ("Big Data"), and as of 2023, artificial intelligence systems deriving utility from public sources of data derived by human interactions. This relationship structure is well-informed by basic definitions in computing and economics, such as "renter", or "slave".









 Data Slave: Renter

As a result of an engineering design process aimed at goals conceived of by DARPA, and subsequent deployment of public access technologies within American civil society in coordination with the National Science Foundation, "We The People" have received an architectural relationship to the utilities built atop this infrastructure. As can be viewed by inspecting the subsequent TCP/IP dependent solutions where human data interactions are enticed/suggested/served/supported/scaled, people have been packaged as "data product" to be sold to "customers of data context" by the "Master" of such web interactions as a webmaster may serve from time to time. Facebook and Google may serve as the leading edge of this infrastructure, where the relationship is best observed and harvested by social graphing systems.


 Root Administrator: Owner

Sovereignty has borders; American Sovereignty is born of the people giving it authority, Individuals all. "We the People" exist as a data structure, a deeply personal one. In every zip code all over our land, in every home where families live and grow, in every pocket where every device is held by those Individual people, a data structure of relationships exists as the deeply held asset of American Sovereignty itself. 

How should you be organized by default?

Own root. Every human life that acquires a birth certificate, whether for your child or another, or for yourself when needed, understands how a data structure works. Lawyers will understand that "Rights" are for people, not birth certificates. But try proving that at the border of American Sovereignty where it matters. Words don't accomplish much in those moments, especially legalese. 

Structure yields results at the border. Root administration over the data structure of American Sovereignty is an edge-driven experience. It happens at the authentic border of authentic Sovereignty itself, or it doesn't. And when it doesn't, there is a reason. This is where failures carry meaning, and can instruct us on flaws in need of fixes.

When DARPA yielded TCP/IP and the NSF made it public, there were other examples that perhaps the notions of future utility were not adequately conceived, and were going to need fixes to flaws faster than originally understood. IPv4 -> IPv6 is one such example... the system was going to run out of addressable spaces to serve the inter-network to users. Other examples are the increasing absence of a default archival system, and IAM work to service the identity space where citizen identifiers are utilized broadly, as the ultimate data silo.

If given a choice, which one do you look to by default for more information:

 Slave: Renter

 Root: Owner

Without any additional information concerning architectural choices, infrastructure requirements, engineering design choices, or participatory patterns of engagement... which do you select?

Functional literacy for American citizens REQUIRES a new consideration of 1976 choices, once more.

15 books that made an impact

I really like Lou Plummer’s list of 15 books which made the most impact on him, which I discovered via Tracy Durnell’s own list: I think you can figure out a lot about a person if you know what books have had the most impact on them. At one point or another, each of these books was my current favorite. They all had a lasting impact on me. I'd love to see your list. Tracy has smartly s

I really like Lou Plummer’s list of 15 books which made the most impact on him, which I discovered via Tracy Durnell’s own list:

I think you can figure out a lot about a person if you know what books have had the most impact on them. At one point or another, each of these books was my current favorite. They all had a lasting impact on me. I'd love to see your list.

Tracy has smartly split hers up into categories. I’ll do the same here. And just as Lou said, I’d love to see your list!

Formative Books

These books disproportionately influenced me when I was a much younger adult, and helped contribute to the way I saw the world in a hundred ways, from my sense of what was possible to my sense of humor.

The Hitchhiker’s Guide to the Galaxy, by Douglas Adams — I don’t quote it, but the clever irreverence still sweeps me off my feet. A large part of me wishes I was Douglas Adams and always will. Constellations: Stories of the Future — a mind-blowing collection of science fiction short stories, some of which became episodes of The Twilight Zone and so on. Jerome Bixby’s It’s a Good Lifeand Fritz Leiber’s A Pail of Air are standouts for me. Something Wicked This Way Comes, by Ray Bradbury — There’s a warm, beating heart at the center of this story, and that’s what draws me in every time (and I’ve reread it countless times). There are better Bradbury books which have probably aged better — you’re probably thinking of them right now — but at the time, it resonated. Maus, by Art Spiegelman — It was much later until I really understood how my own family was affected by WWII, but I connected to this hard. It was also the first graphic novel that made me really think about the possibilities of the form: something that was clearly far beyond superheroes and fantasy. The Handmaid’s Tale, by Margaret Atwood — Practically a documentary at this point, but it’s always been a riveting work of speculative fiction that does what that genre does best: help us grasp with elements of our present. To most of us, it’s a warning. To the Heritage Foundation, I guess it’s a manual. 1984, by George Orwell — It’s hard to imagine a more culturally influential science fiction novel. I love it: although it has a lot to say, I find it to be a page-turner. If you haven’t read Sandra Newman’s follow-up, Julia, run to get it: it’s an impressive work of fiction in its own right that reframes the story in brilliant ways. Microserfs, by Douglas Coupland — Coupland sometimes reads like a funnier Bret Easton Ellis (which is to say zeitgeisty but hollow — Shampoo Planet and The Rules of Attraction are cousins), but at his best he captures something real. Microserfs gave me that first taste of the community and camaraderie around building software together: it’s set in an earlier version of the industry than I got to be a part of, but its depiction of those early years is recognizable. Even the outlandish characters don’t feel out of place. I don’t think it’s probably aged at all well, but it resonated with me hard in my early twenties. Motivating External Change

These books helped me think about how we need to change, and what we might do.

The Jakarta Method: Washington’s Anticommunist Crusade and the Mass Murder Program That Shaped Our World, by Vincent Bevins — I’m convinced that every American citizen should read this, in order to better understand how we show up in the world. (Spoiler alert: we don’t show up well.) Evicted: Poverty and Profit in the American City, by Matthew Desmond — Visceral, accessible, memorable reporting on poverty and housing. Again, it should probably be required reading for American citizens. The Ministry for the Future, by Kim Stanley Robinson — There’s a very silly passage in this book about the role of blockchain in solving climate change (come on), as well as quite a bit in favor of climate engineering, which I think is highly dubious bordering on terrifying. But at the same time, the novel succeeds at painting a visceral picture of what the effects of the climate crisis could be. Caste: The Origins of Our Discontents, by Isabel Wilkerson — A key to understanding America. There’s a lot spelled out here that I simply didn’t know, running the gamut from the details of peoples’ everyday lived experiences to the chilling fact that Hitler based his Nazi caste system on Jim Crow. Books That Changed Me

These books either left me a different person somehow or touched something in me I didn’t know existed.

Kindred, by Octavia Butler — I wish I’d discovered Butler earlier. Her work is immediate and deeply human, and while it shouldn’t have had to change a whole genre, it absolutely did. Parable of the Sower is seismic, of course, and rightly famous. (It’s also getting to be a harder and harder read in the current climate.) But it was Kindred that opened the doors to a different kind of science fiction to me, and through it, all kinds of possibilities. How High We Go in the Dark, by Sequoia Nagamatsu — I have never read a more effective metaphor for grief and change. I read it when I was in the depths of grief myself, and the way this book captures the nuance, the brutality, and the beauty is poetry. I still think about one chapter almost daily. (It’s the rollercoaster. If you know, you know.) The Color Purple, by Alice Walker — A breathtaking example of a modern novel: a masterclass in form as well as content. Not a word is wasted in bringing the lived experiences of her characters to life (and through them, so many more). I’ve read this many times, and I’ve never made it through without absolutely weeping. Bird by Bird: Some Instructions on Writing and Life, by Anne Lamott — So often recommended to writers for really good reasons, Bird by Bird is not just the best book I’ve ever read about writing but also about embarking upon any large project. It’s hopeful, nourishing, actionable, and lovely. Its lessons still motivate me.

Do you have a list of your own that you would like to share? Let me know!

Introducing Plausible Community Edition

[Plausible Analytics]

"We’re real people who have rent to pay and mouths to feed. We make $300 per month from donations from our self-hosted users. It would take us more than ten years of donations to pay one month of salary for our small team. If we cannot capture the economic value of our work, the project will become unsustainable and die."

It's more than a little painful to see new open source businesses re-learn what I and other open source founders have learned over time.

I'm fully in support of Plausible moving to AGPL and introducing a Contributor License Agreement, but I don't believe this will be enough. Indeed, Plausible is moving to "open core" and privatizing some of the more lucrative features:

"We’re also keeping some of the newly released business and enterprise features (funnels and ecommerce revenue metrics at the time of being) exclusive to the business plan subscribers on our Plausible Analytics managed hosting."

What's particularly interesting to me is that they're maintaining source availability for these features - it's just that they're not going to be released under an open source license.

Open source purists might complain, but I believe it's better for the project to exist at all and use licensing that allows for sustainability rather than to maintain open source purity and find that the developers can't sustain themselves. I'd love for these things to be compatible, but so far, I don't believe that they are.

‘It’s about survival’: Athens mayor focuses on getting capital through extreme heat

[Helene Smith at The Guardian] "Barely six months into the job, the mayor of Athens’s top priority is simple: ensuring that the people of Greece’s capital – mainland Europe’s hottest metropolis – survive the summer. After a June that was the hottest on record, the city has already witnessed record-breaking temperatures and wildfires." We're deeply into the climate crisis at

[Helene Smith at The Guardian]

"Barely six months into the job, the mayor of Athens’s top priority is simple: ensuring that the people of Greece’s capital – mainland Europe’s hottest metropolis – survive the summer. After a June that was the hottest on record, the city has already witnessed record-breaking temperatures and wildfires."

We're deeply into the climate crisis at this point; a major city having to make major changes in order to "survive the summer" is just another example.

When you get into the detail, it's terrifying - particularly considering that we're still only at the foothills of where the crisis will lead us:

“It’s not a matter of lifestyle, or improving the quality of life; it’s about survival when 23% of the green lung around Athens has in recent years been destroyed by fires. It’s vital we have more trees, more air-conditioned community centres and more water stations on our streets and squares.”

Over time, we're going to see mass migrations and real, sustained changes to the way people live. We're also going to see a great deal of suffering. These are things we've been warned about for many decades, but the stories are transitioning from projections from climate experts to being the news headlines.

The onus is on the international community to respond to the crisis with robust energy, but we've been waiting for decades for this to really happen. Instead we get carbon trading schemes and economic deals that don't cut to the core of the problem.

There's an individual responsibility, too. These days that responsibility goes beyond making sensible choices about our own energy use (although most of us don't) and extends to voting, taking to the streets, and making it clear to our leaders that continued inaction is not acceptable.

If there isn't change, wars will be fought over this. In a certain light, they already are.

Substack rival Ghost federates its first newsletter

[Sarah Perez at TechCrunch] "Newsletter platform and Substack rival Ghost announced earlier this year that it would join the fediverse, the open social network of interconnected servers that includes apps like Mastodon, Pixelfed, PeerTube, Flipboard and, more recently, Instagram Threads, among others. Now, it has made good on that promise — with its own newsletter as a start.

"Newsletter platform and Substack rival Ghost announced earlier this year that it would join the fediverse, the open social network of interconnected servers that includes apps like Mastodon, Pixelfed, PeerTube, Flipboard and, more recently, Instagram Threads, among others. Now, it has made good on that promise — with its own newsletter as a start."

I'm certain that this is a large part of the future of how information will be disseminated on the internet - and how publishers will run subscription programs. Subscribers who use the fediverse see the benefit of rich content that they can reshare and comment on; publishers get to understand a lot more about their subscribers than they would from the web or email newsletters.

Ghost's reader will certainly be augmented by other, standalone readers that work a bit like Apple News. Its fediverse publishing capabilities will be followed by other content management systems. Notably, Automattic has been working on fediverse integration, for example, and Flipboard has been doing amazing work in this area.

I'm also convinced there's room for another fediverse-compatible social network that handles both long and short-form content in a similar way to Substack's articles and Notes. If someone else doesn't build that, I will.

Rural Republicans Pushing Back Against School Voucher Expansions

[Alec MacGillis at ProPublica] "Voucher advocates, backed by a handful of billionaire funders, are on the march to bring more red and purple states into the fold for “school choice,” their preferred terminology for vouchers.

[Alec MacGillis at ProPublica]

"Voucher advocates, backed by a handful of billionaire funders, are on the march to bring more red and purple states into the fold for “school choice,” their preferred terminology for vouchers. And again and again, they are running up against rural Republicans like Warner, who are joining forces with Democratic lawmakers in a rare bipartisan alliance. That is, it’s the reddest regions of these red and purple states that are putting up some of the strongest resistance to the conservative assault on public schools."

This is heartening to see: a bipartisan push against the school voucher system. Public schools are important social infrastructure that deserve significantly more investment rather than having funds siphoned away to support exclusive institutions. A free market for schools is not the way - and clearly, the communities who would be most affected by a voucher system see this too.

This also feels like one of those rare moments where some Republicans are actively practicing old-school conservatism: the kind that isn't drawn from The Handmaid's Tale. That's nice to see, and I'd love to see more of it.

"[Republican Representative] Greene believes vouchers will harm his district. It has a couple of small private schools in it or just outside it — with student bodies that are starkly more white than the district’s public schools — but the majority of his constituents rely on the public schools, and he worries that vouchers will leave less money for them."

Exactly. Not to mention a worse education.

The Pragmatic Engineer

What is Old is New Again

The past 18 months have seen major change reshape the tech industry. What does this mean for businesses, dev teams, and what will pragmatic software engineering approaches look like, in the future?

👋 Hi, this is Gergely. I give one conference talk per year: this was the one for 2024. It’s my best attempt to summarize the sudden changes across the tech industry and what they will mean for the next few years of software engineering.

To keep up with how the tech industry is changing, subscribe to The Pragmatic Engineer Newsletter, where I offer ongoing analysis. Readers of the newsletter have received many of the insights in this talk months ahead of the presentation.

What is the underlying reason for all the sudden change is happening across the tech industry, and how is the software engineering industry likely to change as a result? I tackled these burning questions in my annual conference talk, “What’s Old is New Again,” which was the keynote at Craft Conference in Budapest, Hungary, in May 2024. If you were there, I hope you enjoyed it! This article contains the full presentation, slides, and summary. I do one conference talk per year, and this was the one for 2024.

If you have some time to spare, you can check out the edited recording below, which has just been published. Shout out to the Craft Conference team for the excellent video production, and for organizing the event!

1. What’s going on?

The tech jobs market, VC funding, IPOs, and Big Tech have been heavily affected by the winds of change in the past 2 years.

Job market

The end of 2021 was the hottest tech hiring market of all time, as described in The Pragmatic Engineer:

“If you are a hiring manager who needs to hire, you’ll know what I’m talking about. There is a fraction of the usual volume of applications, closing is more difficult, and candidates ask for compensation outside target levels. You might have had people verbally accept and then decline for a better offer. A hiring manager on the market:

“Never before has it been this challenging, and in all regions. I remember seeing a heated market before in India a few years back. However, the current environment is many times magnified. We are seeing the same type of intensified competition in the US, UK, EU, Eastern Europe, South America... Heck, just about everywhere. We are predicting this to last late in the year.” – a tech company with offices on most continents.

Analyzing the situation back then, I outlined six factors causing that “perfect storm” in the jobs market which turned it into an employee’s dream.

Six months later in February 2022, the New York Times (NYT) ran an article coming to a similar conclusion that tech companies faced a hiring crisis. However, by the time the NYT noticed, the job market was already changing fast again…

April and May 2022 saw unexpected layoffs:

One-click checkout startup Fast went bankrupt overnight, a year after raising $100M

Klarna let go 10% of staff in an unexpectedly massive cut

Several other companies followed with cuts: Gorillas, Getir, Zapp (instant delivery,) PayPal, SumUp, Kontist, Nuri (fintech,) Lacework (cybersecurity,) and many others.

Fall 2022 saw the big cuts continue, with Lyft, Stripe, CloudKitchens, Delivery Hero, OpenDoor, Chime, MessageBird, and others slashing 10% of their jobs or more.

One thing connected many redundancies: they happened at loss-making companies, so were easier to justify than at businesses that were in the black.

But then profitable companies started making cuts, too. In November 2022, Meta let go 11,000 people (13% of staff) in what were the first-ever layoffs at the social media giant. A few months later, Google, Microsoft, and Amazon followed suit; creating the biggest spike in job cuts to date.

Before 2020, VC investment in startups was rising steadily. Then in 2021, the pace of investment exploded; nearly doubling:

Since then, VC investment has steadily fallen. In Q1 of this year, it was at the same level as 2018!

Quarterly VC investments, 2019-2024 IPOs

2021 was a standout year for public offerings, as a relative flood of tech companies floated on the stock market.

IPOs spiked in 2021. Source: Pitchbook

For a sense of just how many IPOs there were that year, here’s just a few of the notable ones: 

GitLab (version control,) Rivian (electric vehicles,) Couchbase (NoSQL database,) Affirm (buy-now-pay-later,) Bumble (dating,) Duolingo (language learning,) Robinhood (trading,) Expensify (expensing,) Nubank (fintech,) Roblox (gaming,) Coinbase (crypto,) Squarespace (domains,) Coupang (e-commerce,) DigitalOcean (hosting,) Toast (restaurant tech,) Coursera (edtech,) Udemy (edtech,) Amplitude (analytics,) AppLovin (mobile analytics,) UiPath (automation,) Monday.com (project management,) Confluent (data streaming,) Didi Chuxing (ridesharing,) Outbrain (advertising,) Nerdwallet (personal finance.)

By comparison, there were precisely zero tech IPOs in 2022, and only three in 2023 (ARM, Instacart, and Klaviyo.) Little did we know at the time, but HashiCorp’s IPO in December 2021 was the last one for 18 months.

The tech giants did large layoffs in early 2023, which were justified with the claim they’d overhired during the pandemic of 2020-2022. However, by the start of this year, Big Tech was still doing mass layoffs, despite not having overhired AND posting record profits. Google was the model case; founded in 1998, it had only done a single mass layoff back in 2008, when 2% of staff (300 people) were let go. Then in January 2023, around 6% of staff were let go. In January 2024, amid record revenue and profits, the search giant cut yet more staff:

Google’s approach looks pretty typical; regardless of record income and profits, Big Tech companies seem to have become comfortable with regularly letting people go.

Google did back-to-back cuts in 2023 and 2024 despite record profits. Source of image on stage: Is Google the “new IBM?”

I analyzed the rationale behind these cuts at the time, writing:

“Meta, Google and Amazon, are not cutting senselessly; they seem to be strategically cutting their cost centers and heavily loss-making divisions. Plus, they are very likely managing low performers out.”

Summing up 

Here are the changes we’re seeing:

Changes over the past two years 2. Why is this happening today?

Something changed around 2022-2023. But what?

An obvious candidate was the end of the pandemic and lockdowns of 2020-2021, as the world slowly returned to normal.

At the time, founders and CTOs told me why their companies were cutting staff, and why their businesses suddenly faced growth challenges. The “macroeconomic environment” was repeatedly mentioned and was echoed in company announcements reporting job cuts. It became clear that changing interest rates had a larger-than-expected role.

In mid-2022, the US Federal Reserve (FED) did something not seen in decades by increasing interest rates dramatically:

Big finance news in mid-2022. Source: NPR What are interest rates, and why are they going up?

We need to take a brief but necessary detour to understand interest rates a bit.

I refer to “interest rates” as the rate set by national central banks. In the US, this is the Federal Reserve (the Fed,) in the UK it’s the Bank of England, and in the EU it’s the European Central Bank (ECB.) These institutions aim to maintain financial stability with a mandate to execute governmental fiscal policy, which may be to increase or decrease consumer spending, increase or decrease inflation, etc. One of the most powerful “levers” a central bank has at its disposal is to set the interest rates that apply to deposits and debts.

In 2022, inflation was at a 40-year-high in the US (9.1% in July 2022), a 30-year-high in the UK (8.6% in August,) and at its highest-ever in the EU (9.2% in 2022.) Governments in these places set fiscal policies to try and pull inflation down to around 2-3%. The Fed, Bank of England, and (ECB) all took the same action: they raised interest rates.

How do higher interest rates slow down the rate of inflation? Here’s an explainer from the BBC

“The Bank of England moves rates up and down in order to control UK inflation - the increase in the price of something over time.

When inflation is high, the Bank, which has a target to keep inflation at 2%, may decide to raise rates. The idea is to encourage people to spend less, to help bring inflation down by reducing demand. Once this starts to happen, the Bank may hold rates, or cut them.

The Bank has to balance the need to slow price rises against the risk of damaging the economy.”

Replace “Bank of England,” with “Fed,” or “ECB,” and it’s the same. Raising rates is a tried-and-testing method for tackling inflation, worldwide.

Why do higher rates matter?

In the US, the interest rate jumped from almost 0% to around 5% in less than a year:

US interest rate from 2021. Source: FRED

To understand whether this rate change was “business as usual,” let’s look back 15 years or so:

Fed interest rate from 2009. Source: FRED

This graph is eye-opening. Dating back to 2009, the interest rate was close to 0%, and then between 2017-2019 it climbed to around 2%. Then it promptly went back to zero due to the pandemic, as the Fed tried to discourage saving and encourage spending in order to stimulate the economy and avert recession.

Now let’s zoom out all way back to 1955 for a sense of what “normal” interest rates typically are, over time:

US interest rates from 1955. Source: FRED

A “wow” point in the graph above reveals that ultra-low interest rates are historically atypical. Let’s mark up the periods when the interest rate was at or below 1%:

Periods when the US interest rate was 1% or lower

Since 1955, there have been a total of 11.5 years of ultra-low “near-zero” interest rates, 11 of which occurred after 2009. That’s why it’s known as a zero interest rate period (ZIRP.)

Interestingly, this ZIRP was not unique to the US. Very similar events played out in Canada, the UK, and the EU, due to the global financial crisis (GFC) of 2007-2008, when the financial system had a near-death experience.

It’s tempting to assume tech is unconnected to finance and interest rates, but the truth is the opposite. This is not me saying it, but Bloomberg analyst and columnist Matt Levine, who’s passionate about the tech industry and explains how fiscal policies affect industry. In 2023, he analyzed the collapse of Silicon Valley Bank:

“Startups are a low-interest-rate phenomenon. When interest rates are low everywhere, a dollar in 20 years is about as good as a dollar today, so a startup whose business model is ‘we will lose money for a decade building artificial intelligence, and then rake in lots of money in the far future’ sounds pretty good. 

When interest rates are higher, a dollar today is better than a dollar tomorrow, so investors want cash flows. (...)

If some charismatic tech founder had come to you [the bank] in 2021 and said ‘I am going to revolutionize the world via [artificial intelligence][robot taxis][flying taxis][space taxis][blockchain],’ it might have felt unnatural to reply, ‘nah, but what if the Fed raises rates by 0.25%?’ This was an industry with a radical vision for the future of humanity, not a bet on interest rates. 

Turns out it was a bet on interest rates though.”

On stage with Matt Levine’s quote on the big screen

When I read this analysis, my instinct was to push back. Surely there could not be such a basic connection between interest rates and tech startups? However, the more I thought about it, the more I saw Levine had a solid point.

Let’s analyze what happens when interest rates rapidly increase from 0% to 5%, as they did:

What happens after a sudden interest rate hike?

Let’s also look at topics this newsletter covers, like VC funding, IPOs, Big Tech, and the job market, and how interest rates affect them:

Less VC funding: Venture capital is a high-risk/high-reward investment type that large pension funds and ultra-high-net-worth individuals invest in. The idea is to put a large sum, such as $100M, into a VC fund and wait around 10 years for a pretty handsome return. The investment might turn into $150M, $200M, and so on. The alternative is to keep it in the bank, but this erodes its value because annual inflation (for example, of 2%) reduces the purchasing power of a dollar, year on year. But with a 5% interest rate, you can turn $100M into $150M at virtually no risk; so why invest in risky tech startups – of which some succeed and some fail – and risk being left with less than the sum of your initial investment in a decade’s time?

Fewer Tech IPOs: Tech companies going public are generally loss-making, as they are still in growth mode; the majority of tech companies going public in 2021 were in this category. In a high-interest environment, investing in them is less tempting because unless they have a definite path to profitability: they could run out of money, thus devaluing your investment. Rivian’s market cap falling from $150B in 2021 to just $10B in 2024 – in part thanks to the risk of running out of money – is such a cautionary example. In contrast, investors can earn an attractive rate of interest by just putting their money in the bank, instead. 

Big Tech profit push. During a ZIRP, the “baseline” return is 0%. When this baseline rises to 5%, profitable companies need a higher profit ratio in order to maintain their valuation. This means Big Tech cuts costs more aggressively in order to make their profits look better, even if already very profitable.

Worse job market. This is due to Big Tech layoffs and fewer startups hiring because there’s less VC funding available.

Let’s compare these with the changes of the past two years, as described in section 1 of this article; ‘What is going on?’

What should logically happen in the tech industry when interest rates suddenly go up

Comparing what we logically should happen with rising interest rates, versus what we are currently seeing:

Expected versus actual. They are pretty much the same!

It may be unexpected, but rising interest rates explain many trends in the tech market. 

4. Smartphone and cloud revolutions

The drop in interest rates from around 2009 drove more venture capital into startups because VC investing is more attractive when interest rates are at rock bottom and the returns from government bonds are low. Two other factors also began to make an impact at around the time of the GFC.

Smartphone revolution

The iPhone launched in 2007 and the now-defunct Windows Phone followed two years later. Smartphones have transformed consumer tech, and were the catalyst for mobile-first tech companies, like Spotify (founded 2006,) WhatsApp (2009,) Instagram (2010,) Uber (2010,) Snap (2011,) and thousands more.

Cloud revolution

At around the same time as smartphones appeared, the first cloud providers launched:

2006: AWS

2008: Azure

2008: Google Cloud

Cloud providers made it much faster and cheaper for startups to build products. Instead of having to buy and operate on-prem servers, they could just rent a virtual server. And if they needed more capacity, they could just pay for it and scale up almost immediately. Early Amazon employee, Joshua Burgin, (now VP of Engineering at VMWare) described it in The past and future of modern backend practices:

“This [cloud] transition enabled early AWS customers like Netflix, Lyft, and Airbnb, to access the same level of computing power as established tech giants, even while these startups were in their infancy. Instead of purchase orders (POs,) months-long lead times, and a large IT department or co-location provider, you only needed a credit card and could start instantly!“

Some of the best-known AWS customers today are Netflix, Airbnb, Stripe, and Twitch. All grew faster – and likely needed less capital – by utilizing the cloud.

Overlap

The smartphone and cloud revolutions coincided almost perfectly with when interest rates fell to zero and then stayed in the deep freeze for a decade:

Key events within the smartphone and cloud revolutions plotted to interest rates

These developments gave VCs even more reason to invest in startups:

New categories of mobile-first startups were around, with potential to become billion-dollar companies if they moved fast. Raising large amounts of capital was crucial to win the market; Uber and Spotify succeeded with this strategy.

Startups could turn investment into growth more efficiently by throwing money at scaling problems by using the cloud, instead of spending years building their own infrastructure. This was another way VC investment helped startups win their respective markets.

It’s likely the 2010s were a golden age for tech startups, due to the ahistorical combination of the longest-ever period of 0% interest rates, and two technological revolutions which kicked off at that time.

Today, another potential tech revolution is heating up: generative AI, and large language models (LLM.) The AI revolution has similarities to the cloud revolution in how AI could also bring efficiency increases (once AI costs decrease from where are today.) However, the AI revolution is very different in nature to the smartphone revolution: this is because AI doesn’t appear to offer a new, initially free, broad distribution channel like the smartphone did for app makers. And the GenAI revolution also began in a high interest rate environment:

GenAI revolution (ChatGPT launch, etc) occurs in a high interest rate environment.

We cover more on the “how” of GenAI in these articles:

5. New reality

So, what is the “new reality” which we work in? Check out this part of the presentation for my take on what it means for software engineers and engineering practices.

Basically, it’s tougher for software engineers to land jobs, and career advancement is slower. For engineering practices, we’ll likely see a push to choose “boring” technology, monoliths become more popular, “fullstack” and Typescript gain more momentum, and more responsibilities “shift left” onto developers.

How will software engineering practices change? Watch the full segment here

Previous newsletters go into even more depth:

6. History repeating?

Change is often unfamiliar and unexpected. Those around for the Dotcom Bust of 2001 must see similarities between today and the sudden changes wrought when the tech bubble burst, back then. Software engineers who were working during that period offer perspectives and tactical advice on how to prioritize career security when job security feels beyond control.

See their advice here.

Takeaways

Sometimes it’s helpful to “zoom out” and take stock of change as it unfolds across tech, in order to understand more about it. The demise of 0% interest rates is a mega-event with notable effects on the tech industry. It’s hard to predict the future – especially in tech, where things change fast – but I find it useful to seek understanding of the underlying forces influencing the direction of the sector.

From one perspective, the history of the tech industry is one of cyclical booms and busts. Innovation is fertile ground for new business opportunities, and I have no doubt there’s many boom times ahead; we just need to recognize them when they happen!

After the keynote, several people shared with me that it had “clicked” with them, in terms of their experience at work, at their friends’ workplaces, and on the job market. One participant said they’re planning their next career step, and understanding the trends at work is helping them to make more considered decisions: 

“Using a soccer analogy: I want to run to the part of the pitch where the ball will be shot forward to, and not to where most players are looking at (where the ball currently is.) I feel I have more information about where the tech industry ‘ball’ will be headed in the next few years, so I can position myself better.”

I hope you found this analysis insightful, and the talk interesting to watch!

Finally, a big thank you to Craft Conference for hosting me. I asked the organizers how the conference did this year, and here are interesting statistics they shared with me:

2,000 attendees: around 1,500 in-person, and the rest online.

80 speakers: 95% of whom attended from abroad. This international roster attracted me to the event.

49 countries from which participants traveled, including Germany, Romania, Norway, Austria, the Netherlands, US, and Serbia, as well as locally-based professionals.

60% of participants were software engineers, 13% engineering managers/team leads, and 10% architects.

Javascript & Typescript are the most popular programming languages among attendees. Java, Python, C#, C+++, PHP, C, Go and Kotlin are next in popularity.

The event is annual and the next edition will take place in spring 2025.

My technology coaching and consulting in 2024

My availability has opened up for a handful of consulting engagements in addition to my regular work as Senior Director of Technology at ProPublica. I’ve founded two startups (both based on open-source technology communities that I also founded). I’ve been a CTO, led product, and invested in early-stage startup ventures. I’ve also taught venture and product design to teams that include startups

My availability has opened up for a handful of consulting engagements in addition to my regular work as Senior Director of Technology at ProPublica.

I’ve founded two startups (both based on open-source technology communities that I also founded). I’ve been a CTO, led product, and invested in early-stage startup ventures. I’ve also taught venture and product design to teams that include startups, top-tier educational institutions, and local newsrooms. My products have been used by social movements and Fortune 500 companies. I would love to help you to move faster and make stronger technology decisions.

Here are some ways I might be helpful to you:

A Sounding Board

I can be your technology and product sounding board for your products and how your product or engineering team is run. I offer regular check-ins, or I can be available on an ad hoc, as-needed basis.

I’ll help you solve problems and coach you through getting to enduring solutions and productive work cultures. In the process, you’ll avoid common pitfalls, take advantage of a new but experienced set of eyes on your problems, and have someone in your corner when you need.

Accelerated Technology Product Sprints

Do you need to quickly evaluate a product idea or a way to solve problems for a customer you’ve identified? Do you need to identify that customer or market?

I can lead you through a short design sprint, either remotely or in person. At the end of it, you’ll have a stronger idea of your user and customer, learned tools for quickly running experiments and making progress, and identified and evaluated the core hypotheses that your product rests upon.

You’ll iterate and get to market faster, increase your product’s chance of success, and build practices in your team to help you move faster long after we’ve finished working together.

Technical Evaluation and Advice

Are you wondering how a technology (perhaps AI or the fediverse) might be used in your business? Do you have an idea in mind that needs to be feasibility-tested?

I’ll learn about your product and business and report on how you can leverage available technology with the time, team, and resources you have.

You’ll more quickly understand what you can build, what’s technically possible, and where the technology opportunities are for your existing business.

Deck Review

Are you presenting a strategy to your board or managers? Are you a startup going out to raise money?

I can give you actionable feedback to help you build your deck and tell a more robust story that has a better chance of getting you to the outcome you’re looking for.

You’ll tell a stronger story, make a deeper emotional impact on your audience, and learn how to tell compelling stories in the future.

Courses

Any of the above can be provided as workshops for your larger course. They are available both in-person and remotely.

Get in Touch

If you’re interested in these — or if you think you could make use of my other skills and experiences — please email me directly at ben@werd.io to arrange an initial meeting. I’m excited to talk to you!

こんにちは、富士榮です。
なんだか想定以上に長いシリーズになってしまっています。 引き続きW3C Verifiable Credentials Overviewを読んでいきます。

Introduction Ecosystem Overview Verifiable Credentials Data Model Securing Credentials Bitstring Status List Additional Publications ようやくメイン部分の最後にあたるBitstring Status Listです。 これは、以前Status List 2021の解説をしたときはDIF(Decentralized Identity Foundation)のスペックだったのがW3Cに移管されたものです。 中身はあんまり変わっていません。相変わらず微妙なスペックです・・・・(そもそも16Kbで実装しちゃうと後からハマる、今時ビット配列をパースするのは面倒くさい・・・など)
何はともあれみていきます。
It is often useful for an issuer of Verifiable Credentials to link to a location where a verifier can check to see if a credential has been suspended or revoked. This additional resource is referred to as a "status list". The simplest approach for a status list, where there is a one-to-one mapping between a Verifiable Credential and a URL where the status is published, raises privacy as well as performance issues. In order to meet privacy expectations, it is useful to bundle the status of large sets of credentials into a single list to help with group privacy. However, doing so can place an impossible burden on both the server and client if the status information is as much as a few hundred bytes in size per credential across a population of hundreds of millions of holders. The Bitstring Status List v1.0 [VC-BITSTRING-STATUS-LIST] specification defines a highly compressible, highly space-efficient bitstring-based status list mechanism. Conceptually, a bitstring status list is a sequence of bits. When a single bit specifies a status, such as "revoked" or "suspended", then that status is expected to be true when the bit is set and false when unset. One of the benefits of using a bitstring is that it is a highly compressible data format since, in the average case, large numbers of credentials will remain unrevoked. If compressed using run-length compression techniques such as GZIP [RFC1952] the result is a significantly smaller set of data: the default status list size is 131,072 entries, equivalent to 16 KB of single bit values and, when only a handful of verifiable credentials are revoked, GZIP compresses the bitstring down to a few hundred bytes.
検証可能な資格情報の発行者は、資格情報が停止または取り消されたかどうかを確認できる場所へのリンクを張ることが有用な場合があります。この追加リソースは「ステータスリスト」と呼ばれます。 検証可能な資格情報とステータスが掲載されている URL との 1 対 1 の対応関係があるステータスリストの最も単純なアプローチは、プライバシーとパフォーマンスの両面で問題が生じます。プライバシーに関する期待に応えるためには、多数の資格情報のステータスを 1 つのリストにまとめてグループとしてのプライバシー保護に役立てる方法が有効です。しかし、数百万人規模の保有者に対して、1つのクレデンシャルにつきステータス情報が数百バイトにも及ぶ場合、サーバーとクライアントの両方に不可能なほどの負担がかかる可能性があります。Bitstring Status List v1.0 [VC-BITSTRING-STATUS-LIST] 仕様では、非常に圧縮率が高く、スペース効率に優れたビットストリングベースのステータスリストの仕組みが定義されています。 概念的には、ビット文字列ステータスリストはビットのシーケンスです。1つのビットが「無効」や「一時停止」などのステータスを指定する場合、そのビットが設定されているときはステータスが有効、設定されていないときはステータスが無効であると見なされます。ビット文字列を使用する利点の一つは、圧縮率が高いデータ形式であることです。平均的な場合、多数のクレデンシャルは有効のままであるからです。GZIP [RFC1952] などのランレングス圧縮技術を使用して圧縮すると、データセットが大幅に縮小されます。デフォルトのステータスリストサイズは 131,072 エントリで、16 KB の単一ビット値に相当します。検証可能なクレデンシャルのうちごく一部にのみ無効化処理が実行された場合、GZIP 圧縮によりビット文字列は数百バイトにまで縮小されます。
まぁ、思想はわかります。 有効性確認をするためにIssuerに問い合わせをしちゃうとHolderがどのVerifierにクレデンシャルを提示しようとしているのかがわかってしまいますから。その意味でStatus Listを独立させた形で持たせるのはわかりますし、あまり情報量を多くするとパフォーマンス問題につながることも理解出来ます。その意味でビットで管理するのも理解はできますが、実装者にとって見積もりが難しいです。131,072までしかクレデンシャルを発行しないのか?後から増やそうと思ったらどうできるのか、諸々考えることはあります。まさにご利用は計画的に。
図9. A visual depiction of the concepts outlined in this section.

The specification introduces the credentialStatus property, as well as some additional sub-properties, that should be used to add this additional information to a Verifiable Credential. Example 11 shows our example from Example 9, combined with the information on the credential status: the purpose of that status information, the reference to the bitstring, and the index into this bitstring for the enclosing credential: この仕様では、Verifiable Credential にこの追加情報を追加するために使用されるべき、credentialStatus プロパティと、いくつかの追加サブプロパティが導入されています。 例 11 は、例 9 の例に、クレデンシャルのステータスに関する情報を加えたものです。ステータス情報の目的、ビット列への参照、およびこのビット列の、クレデンシャルを囲むためのインデックスを示しています。
EXAMPLE 11: Verifiable Credential with a Reference to a Status List { "@context": [ "https://www.w3.org/ns/credentials/v2", "https://www.example.org/vocabs/alumni" ], "id": "https://university.example/Credential123", "type": ["VerifiableCredential", "ExampleAlumniCredential"], "issuer": "did:example:2g55q912ec3476eba2l9812ecbfe", "validFrom": "2010-01-01T00:00:00Z", "credentialSubject": { "id": "https://www.example.org/persons/pat", "name": "Pat", "alumniOf": { "id": "did:example:c276e12ec21ebfeb1f712ebc6f1", "name": "Example University" } }, "credentialSchema": { "id": "https://university.example/Credential123-schema-credential", "type": "JsonSchemaCredential" }, "credentialStatus": { "id": "https://university.example/statuslist#123456", "type": "BitstringStatusListEntry", "statusPurpose": "revocation", "statusListIndex": "123456", "statusListCredential": "https://university.example/CredentialStatusList" }, "proof": { "type": "DataIntegrityProof", "cryptosuite": "ecdsa-rdfc-2019", "created": "2010-01-01T00:00:00Z", "expires": "2040-01-01T00:00:00Z", "verificationMethod: "did:example:2g55q912ec3476eba2l9812ecbfe#ecdsa-public-key" "proofPurpose": "assertionMethod" "proofValue": "zQeVb…Wx" } 

The statusListCredential property, when dereferenced, should return a separate Credential for the status list. The status list itself is the subject of that Credential (which, of course, can also be signed). An example is:

statusListCredential プロパティは、参照解除されると、ステータスリスト用の個別のクレデンシャルを返します。ステータスリスト自体がそのクレデンシャルの対象となります(もちろん、署名することもできます)。例:

EXAMPLE 12: A Credential for a Bitstring Status List { "@context": [ "https://www.w3.org/ns/credentials/v2" ], "id": "https://university.example/CredentialStatusList", "type": ["VerifiableCredential", "BitstringStatusListCredential"], "issuer": "did:example:2g55q912ec3476eba2l9812ecbfe"", "validFrom": "2005-01-01T00:00:00", "credentialSubject": { "id": "https://university.example/statuslist#list", "type": "BitstringStatusList", "statusPurpose": "revocation", "encodedList": "uH4sIAAAAAAAAA-3BMQEAAADCoPVPbQwfoAAAAAAAAAAAAAAAAAAAAIC3AYbSVKsAQAAA" } 

}

The core property in this case is encodedList, which is a base64url encoded version of the GZIP compressed bitstring status list.

このケースで重要なプロパティはencodedListで、GZIP圧縮ビット文字列ステータスリストのbase64urlエンコード版です。


まぁ、この辺りを含め以前書いたポストでカバー済みなので省略します。

一応これで本編は終わりです。

追加リソース部分は解説するかもしれませんししないかもしれません。

The only goal that really matters is building a stable, informed, democratic, inclusive, equitable, peaceful society where everyone has the opportunity to live a good life. One where we care for our environment, where we champion democracy, science, education, and art, where equality for all is seen as a virtue, where truth is spoken to power, and where nobody can fall through the cracks.

Let's get there together.


Just a Theory

Introducing Go SQL/JSON Path and Playground

Introducing the SQL/JSON Path package, a PostgresSQL-compatible jsonpath parser and executor in Go. Also: a Wasm-based playground!

For a personal project, I needed to parse and execute PostgreSQL-compatible jsonpath expressions.1 So I’ve spent just about every spare evening and weekend the last several months porting Postgres jsonpath to Go, and it’s finally ready to ship.

Introducing Go SQL/JSON, featuring the path package. This project provides full support for all of the PostgresSQL 17 jsonpath features2 in the Go programming language. An example:

package main import ( "context" "encoding/json" "fmt" "log" "github.com/theory/sqljson/path" "github.com/theory/sqljson/path/exec" ) func main() { // Parse some JSON. var value any err := json.Unmarshal([]byte(`{"a":[1,2,3,4,5]}`), &value) if err != nil { log.Fatal(err) } // Parse a path expression and execute it on the JSON. p := path.MustParse("$.a[*] ? (@ >= $min && @ <= $max)") res, err := p.Query( context.Background(), value, exec.WithVars(exec.Vars{"min": float64(2), "max": float64(4)}), ) if err != nil { log.Fatal(err) } fmt.Printf("%v\n", res) // Output: [2 3 4] }

I think the API is decent, but may implement better patterns as I discover them. Overall I’m quite satisfied with how it turned out, and just how well its implementation and performance compare to the original.

🛝 Playground

But why stop there? One of the nice things about this project is that Go supports compiling applications into WebAssembly (a.k.a. Wasm) via Go WebAssembly. Borrowing from the Goldmark project, I created and published the sqljson/path playground and populated the docs with links for all of its examples.

Now anyone can experiment with SQL/JSON path expressions, and share links to demonstrate patterns and techniques. The Playground is a stateless JavaScript/Wasm web application: data persists only in permalink URLs.3

🛝 Try this example Playground permalink right now!4

The Path Ahead

I’ve enjoyed learning how to implement a lexer, a goyacc parser, an AST, and an execution engine. The Playground was a bonus bit of fun!

I’m stoked to build cool stuff on this package, but don’t know whether anyone else will find it useful. If you do — or just enjoy messing about on the Playground, let me know!

“Whatever for,” you ask? Well, aside from wanting to see if I could do it, this post describes a POC. Now I’m working to create the real thing — done right and entirely from scratch. ↩︎

Well, nearly full. The only missing feature is the datetime(template) method. See also the comprehensive compatibility notes↩︎

And whatever data GitHub Pages collect 😔. ↩︎

BKA: Höchststand an Falschverdächtigungen aufgrund der freiwilligen Chatkontrolle

Von den Chats, die mithilfe der “freiwilligen Chatkontrolle” der US-Konzerne (allen voran Meta) an die Polizei geleakt werden, ist ein so geringer Anteil wie noch nie tatsächlich strafrechtlich relevant – zuletzt sogar weniger als die Hälfte. Dies ergibt sich aus dem heute veröffentlichten „Bundeslagebild Sexualdelikte“ des BKA. Danach ist die Zahl der zumeist automatisiert an das BKA ausgeleiteten Chatverläufe von 2022 auf 2023 massiv gestiegen (von 136.450 auf 180.300 Chats), die Zahl der für strafrechtlich relevant befundenen Chatverläufe aber zurückgegangen (von 89.850 auf 89.350 Chats).

„Die Zerstörung unseres Briefgeheimnisses nimmt immer dramatischere Ausmaße an“, kritisiert der Europaabgeordenete der Piratenpartei Dr. Patrick Breyer. „Erstmals sind mehr als die Hälfte der ausgeleiteten Chats völlig legal. Noch nie sind so viele private und intime Familienfotos, Partnerfotos, Sexting durch Kinder usw. in Hände gelangt, in die sie nicht gehören und in denen sie nicht sicher sind. Dass die Bundesregierung diese freiwillige Chatkontrolle unterstützt, ist der völlig falsche Weg. Unsere Kinder werden durch die Chatkontrolle massenhaft kriminalisiert, anstatt sie zu schützen – selbst wenn sie aus eigenen Stücken Selbstaufnahmen verschicken.

Nach meinen Informationen ist die Ursache dieser Rekord-Unzuverlässigkeit, dass einige Plattformen angefangen haben, Textchats nach Schlüsselwörtern zu scannen, denen jeder Bezug zu Kindesmissbrauch fehlt. Mit den privaten Schnüffelalgorithmen werden Millionen verdient, die Hersteller lobbyieren aber gegen jegliche Zuverlässigkeitsanforderungen, Transparenz und unabhängige wissenschaftliche Überprüfung.
Die von der Bundesregierung unterstützte eigenmächtige Chatkontrolle 1.0 ist ein gefährlicher Irrweg der US-Konzerne. Sie konnte die Menge des ‚verdächtigen‘ Materials an den teilnehmenden Plattformen nie eindämmen. Die Entlastung der Polizei von der Flut zum großen Teil falscher Verdachtsmeldungen würde Kapazitäten für die verstärkte Verfolgung und verdeckte Ermittlungen gegen organisierten Kindesmissbrauchs freimachen, was Kinder wirklich schützt und die Hintermänner stoppt. Big Tech unterlässt wirklich wirksame Schutzmaßnahmen durch sichere Gestaltung sozialer Netzwerke (Security by Design), weil sie ihren Profiten schaden würden. Warum werden Nutzer etwa nicht durchgängig und altersunabhängig gefragt, bevor ihre Fotos öffentlich sichtbar sind und sie für Fremde ansprechbar sind? Naheliegende Schutzmaßnahmen vor sexueller Annäherung sind wirksamer als jede ungezielte Massenüberwachung!”

Breyer klagt aktuell gegen die freiwillige Chatkontrolle vor dem Oberlandesgericht Schleswig. Auch die Klage eines Missbrauchsbetroffenen ist anhängig.

📖 A Psalm for the Wild-Built

“You’re an animal, Sibling Dex. You are not separate or other. You’re an animal. And animals have no purpose. Nothing has a purpose. The world simply is. If you want to do things that are meaningful to others, fine! Good! So do I! But if I wanted to crawl into a cave and watch stalagmites with Frostfrog for the remainder of my days, that would also be both fine and good. You keep asking why your work is not enough, and I don’t know how to answer that, because it is enough to exist in the world and marvel at it. You don’t need to justify that, or earn it. You are allowed to just live. That is all most animals do.”

I tend to read whatever the opposite of cozy science fiction is: angry and worried about the world, building tension from speculative extrapolations of what could go wrong. This, on the other hand, is science fiction that encourages you to just chill for a minute.

I don’t know if I could read a lot of this, because I am angry and worried about the world, and reading other peoples’ words along the same lines is cathartic. But the message here — that you don’t need to justify yourself, that you can just be — is soothing, and was necessary for me. And it’s all done with wit and care. What a delightful novella.

Seymour and Brownie

My family, on my dad’s side, were Jews from Poland and Ukraine. His parents came to America before the shit hit the fan, but I grew up knowing two people who weren’t so lucky. Seymour Mayer lived across the street during my teens. And Annie Braunschweig, who we knew as Brownie, had taken care of my sister and me as four- and five-year-old kids when our mom – unusually at that time – went back to work full-time teaching at a university. Both Seymour and Brownie were survivors of Nazi concentration camps, with tattooed numbers on their arms.

I never heard Seymour talk about it. Brownie rarely did, though I remember one story about a mother who tossed her swaddled baby to a stranger as the train was leaving to take her to the gas chambers.

Very few survivors remain. And there are not many of us who have known survivors. I’ve thought a lot, over the years, about what happens when that kind of personal connection ends, and living memories fall off the continental shelf into the deep ocean of history. I suspect the Holocaust may seem no more real, to many born in this century, than the Spanish Inquisition.

I don’t know if Seymour and Brownie ever read “It Can’t Happen Here” but I am pretty sure they’d have thought it absolutely can, they’d be even more horrified in this moment than many of us are, and they’d reject the fatalism that I see taking root among friends and acquaintances.

“It hasn’t happened yet,” they’d say, “you can still prevent it, do not despair prematurely, there is still time, but you must find a way to focus your efforts and unite all whose votes can matter.”

こんにちは、富士榮です。

引き続きW3C Verifiable Credentials Overviewを読んでいきます。


Introduction Ecosystem Overview Verifiable Credentials Data Model Securing Credentials Bitstring Status List Additional Publications 今回も引き続き4番目のSecuring Credentialsを見ていきます。 続きなのでCryptosuitesのところからですね。
2.3. Cryptosuites
The Working Group publishes three cryptosuite documents: Data Integrity ECDSA Cryptosuites v1.0 [VC-DI-ECDSA], Data Integrity EdDSA Cryptosuites v1.0 [VC-DI-EDDSA], and Data Integrity BBS Cryptosuites v1.0 [VC-DI-BBS]. As their name suggests, the documents rely on existing cryptographic signature schemes: the Elliptic Curve Digital Signature Algorithm (ECDSA) specification [FIPS-186-5], the Edwards-Curve Digital Signature Algorithm (EdDSA) specification [RFC8032], and the BBS Signature Scheme [CFRG-BBS-SIGNATURE], respectively. Figure 8 provides an overall view of the six cryptosuites defined by the three recommendations. They all implement the general structure of proofs as described in 4.2.1 Generic Data Integrity Structure. As shown on the figure, one axes of differentiation is the data transformation function, i.e., the canonicalization of the JSON serialization: two cryptosuites use JSON Canonicalization (JCS) [RFC8785], the others use RDF Dataset Canonicalization (RDFC-1.0) [RDF-CANON]. The other axis is whether the cryptosuite provides selective disclosure, which is the case for two of the six cryptosuites. ワーキンググループは、3つの暗号スイート文書を公開しています。データ完全性ECDSA暗号スイートv1.0 [VC-DI-ECDSA]、データ完全性EdDSA暗号スイートv1.0 [VC-DI-EDDSA]、データ完全性BBS暗号スイートv1.0 [VC-DI-BBS]です。これらの文書はその名称が示すように、それぞれ、楕円曲線デジタル署名アルゴリズム(ECDSA)仕様書 [FIPS-186-5]、エドワーズ曲線デジタル署名アルゴリズム(EdDSA)仕様書 [RFC8032]、BBS 署名方式 [CFRG-BBS-SIGNATURE] といった既存の暗号署名方式に基づいています。 図 8 は、3 つの勧告で定義された 6 つの暗号スイートの全体像を示しています。これらはすべて、4.2.1 汎用データ完全性構造で説明されている証明の一般的な構造を実装しています。図に示されているように、差別化要因の1つはデータ変換機能、すなわちJSONシリアライズの正規化です。2つのcryptosuiteはJSON Canonicalization (JCS) [RFC8785]を使用しており、他のcryptosuiteはRDF Dataset Canonicalization (RDFC-1.0) [RDF-CANON]を使用しています。もう一つの軸は、暗号スイートが選択的開示機能を備えているかどうかです。6つの暗号スイートのうち2つは選択的開示機能を備えています。

図8. Generic view of the proof generation steps.


この図にあるように、3つの暗号化スイートを定義しており、それぞれについて正規化のパターンで分類をしています。また大切なのは選択的開示(Selective Disclosure)を実現できるかどうか、です。このW3CのドキュメントにあるBBSか、IETFのSD-JWT-VCなのか、ということがしばしば対立軸的に語られますがいずれにしても選択的開示は必要になるケースが増えてくると思うので、この辺りを中心に押さえていけると良いと思います。

NOTE 

A common characteristics of all these cryptosuites is that keys must always be encoded using the Multikey encoding. The keys, whose exact formats are defined in the respective signature scheme specifications, also carry the choice of the hash functions to be used by the proof generation algorithm. This provides yet another differentiation axis among cryptosuites although, in practice, SHA-256 [RFC6234] is usually used.

これらの暗号スイートに共通する特徴は、キーを常にマルチキーエンコーディングでエンコードしなければならないことです。キーの正確なフォーマットは、それぞれの署名スキームの仕様で定義されていますが、証明生成アルゴリズムで使用されるハッシュ関数の選択もキーに含まれます。これにより、暗号スイート間の差別化要素がさらに1つ追加されますが、実際には通常、SHA-256 [RFC6234] が使用されます。

2.3.1. Full Disclosure Schemes

The two EdDSA cryptosuites, as well as ecdsa-rdfc-2019 and ecdsa-jcs-2019, follow the proof generation pipeline as described in 4.2.1 Generic Data Integrity Structure: the Credential is canonicalized (using either JCS or RDFC-1.0), the result is hashed (using the hash functions as defined by the signature key), and the proof is generated using that hash value. There is, however, an extra twist: the same pipeline is also used on a set of claims called "proof options", i.e., all the claims of the proof graph except proofValue. This set of claims is therefore also canonicalized and hashed, following the same process as for the Credential, yielding a second hash value. It is the concatenation of these two values that is signed by EdDSA or ECDSA, respectively, producing a value for the proofValue property.

2つのEdDSA暗号スイート、ecdsa-rdfc-2019およびecdsa-jcs-2019は、4.2.1で説明されている証明生成パイプラインに従います。一般的なデータ完全性構造:クレデンシャルは正規化され(JCS または RDFC-1.0 を使用)、その結果はハッシュ化され(署名鍵で定義されたハッシュ関数を使用)、そのハッシュ値を使用して証明が生成されます。ただし、さらに別の工夫がされています。同じパイプラインが「proof options」と呼ばれる一連のクレームにも使用されているのです。つまり、proofValue を除く証明グラフのすべてのクレームです。この一連のクレームも、クレデンシャルと同じプロセスに従って正規化およびハッシュ化され、2つ目のハッシュ値が算出されます。これらの2つの値の連結が、EdDSAまたはECDSAによってそれぞれ署名され、proofValueプロパティの値が生成されます。

署名対象となるクレデンシャルに加えてproof optionsに関しても変換・ハッシュ化・Proof作成というステップを踏むわけですね。

2.3.2. Selective Disclosure Schemes
The ecdsa-sd-2023 and bbs-2023 cryptosuites provide selective disclosures of individual claims. In both cases, the process separates the "Base Proof" (calculated by the issuer), and the "Derived Proof" (which is typically calculated by the holder when selectively presenting the credential claims to the verifier). The challenge is that the verifier should check that the holder can be trusted when verifying a partial value, without having access to the full original data. To calculate the Base Proof, the Credential is supplemented with extra information that separates the "mandatory" and "non-mandatory" claims. Using that extra information, the transformation step described in 4.2.1 Generic Data Integrity Structure does not only canonicalize the Credential, but also transforms it by explicitly separating these two types of claims into their own sets. Furthermore, each non-mandatory claim must be signed individually, yielding a series of signatures. The final Base Proof is, conceptually, the concatenation of all these signatures and related informations like the separation of mandatory and non-mandatory claims. The Derived Proof is generated by the holder, when presenting the (derived) Credential. These data are combined with the kind of selective disclosure requests the holder is prepared to honor; it is the combination of all these data that are used for the creation of a Derived Proof that is forwarded to the verifier.

ecdsa-sd-2023およびbbs-2023暗号スイートは、個々のクレームを選択的に開示します。いずれの場合も、プロセスは「ベースプルーフ」(発行者によって算出)と「派生プルーフ」(通常、検証者にクレデンシャルクレームを選択的に提示する際に保有者によって算出)を分離します。検証者は、元のデータ全体にアクセスすることなく、部分的な値を検証する際に、保有者が信頼できることを確認する必要があります。 

ベースプルーフを計算するために、クレデンシャルには「必須」と「非必須」の主張を区別する追加情報が追加されます。この追加情報を使用して、4.2.1 汎用データ完全性構造で説明されている変換ステップでは、クレデンシャルを正規化するだけでなく、これらの2種類の主張をそれぞれのセットに明示的に分離して変換します。さらに、各非必須の主張は個別に署名され、一連の署名が生成されます。最終的なベースプルーフは、概念的には、これらの署名と必須および非必須の主張の分離などの関連情報の連結です。

派生証明は、(派生)クレデンシャルを提示する際に、保有者によって生成されます。これらのデータは、保有者が応じる用意のある選択的開示要求の種類と組み合わせられます。検証者に送付される派生証明の作成には、これらのデータの組み合わせがすべて使用されます。

選択的開示をするためにベースプルーフと派生プルーフに分けるんですね。開示したくない属性を落としても全体として完全であるということを示さなければならないので、開示されない可能性のある派生クレームについては個別で署名をしていくということのようです。

2.4. Example: the Core Example Secured with ECDSA
The Credential example, shown in Example 1, and enriched with a reference to a JSON Schema in Example 3, can be secured via an embedded proof as follows:

例 1 の「Credential」の例では、例 3 の JSON スキーマへの参照を付加することで、次のように埋め込み証明を使用してセキュリティ保護することができます。

EXAMPLE 9: An ECDSA proof added to a Credential { "@context": [ "https://www.w3.org/ns/credentials/v2", "https://www.example.org/vocabs/alumni" ], "id": "https://university.example/Credential123", "type": ["VerifiableCredential", "ExampleAlumniCredential"], "issuer": "did:example:2g55q912ec3476eba2l9812ecbfe", "validFrom": "2010-01-01T00:00:00Z", "credentialSubject": { "id": "https://www.example.org/persons/pat", "name": "Pat", "alumniOf": { "id": "did:example:c276e12ec21ebfeb1f712ebc6f1", "name": "Example University" } }, "credentialSchema": { "id": "https://university.example/Credential123-schema-credential", "type": "JsonSchemaCredential" }, "proof": { "type": "DataIntegrityProof", "cryptosuite": "ecdsa-rdfc-2019", "created": "2010-01-01T00:00:00Z", "expires": "2040-01-01T00:00:00Z", "verificationMethod: "did:example:2g55q912ec3476eba2l9812ecbfe#ecdsa-public-key" "proofPurpose": "assertionMethod" "proofValue": "zQeVb…Wx" } 

}

When dereferenced, the URL did:example:2g55q912ec3476eba2l9812ecbfe#ecdsa-public-key should return an ECDSA public key in Multikey format, for example:

dereferenced された URL、:example:2g55q912ec3476eba2l9812ecbfe#ecdsa-public-key は、例えば次のような Multikey 形式の ECDSA 公開鍵を返すべきです。

EXAMPLE 10: An ECDSA public key { "@context": [ "https://www.w3.org/ns/did/v1", "https://w3id.org/security/multikey/v1" ], "id": "did:example:2g55q912ec3476eba2l9812ecbfe#ecdsa-public-key", "type": "Multikey", "controller": "did:example:2g55q912ec3476eba2l9812ecbfe", "publicKeyMultibase": "z42twTcNeSYcnqg1FLuSFs2bsGH3ZqbRHFmvS9XMsYhjxvHN" 

}

Note that the value of the verificationMethod property may have been the public key itself, instead of a reference to a separate resource containing the key.

検証方法プロパティ(verificationMethod)の値は、キーを含む別のリソースへの参照ではなく、公開キーそのものである可能性があることに注意してください。


proof内のverificationMethodのプロパティに設定されたdidに関連するdid documentから公開鍵を取得するわけですね。(注意書きにもある通り公開鍵そのものが設定されるケースもある)


ということでこれでSecuring credentialsの章はおしまいです。

次から本文の最後となるbitstring statuslistの話です。要するにCredentilasのRevokeをした場合のステータスをどうやって表すのかという話ですね。

ではまた次回。

この分野は素人である上、以下は数行のメモと記憶から抜き出したものです。不正確なことや書き落としていることも沢山あると思うので、白浜組の方々におかれましては、適宜ご指摘をしていただければと思います。なお、私の感想的なところも多分に混じっていると思うのでその点はご容赦いただければと思います。明らかにパネルでは出なかったことに関しては、斜体字にしています。また、セッション最後にあったQ&Aの内容も本体にできるだけ取り込むようにしています。

要約

このパネルディスカッションでは、生成AIの発展と課題、クラウドシフトの影響、最近の大規模なランサムウェア事件について議論されました。生成AIの発展により、効率化が進む一方、不適切な情報の生成や流布のリスクが高まっていること、クラウドシフトによるコスト削減の一方でベンダー管理の難しさ、ランサムウェア事件の深刻な被害とフェーズが変わったことの指摘、および対策の必要性が指摘されました。

生成AIの発展と課題

生成AIの発展により業務の効率化が期待される一方で、情報漏洩のリスクが当初指摘されました。しかし、その後契約などによる制御によって情報漏洩が大きな問題になることは考えにくくなってきました。しかしその一方、コンテンツに関する権利の希薄化や不適切なコンテンツやマルウェア作成のリスクが高まっています。

例えば、先日生成AIを使ってスマホ向けのランサムウェアを作ったとされる人が逮捕される事例が出ました。スマホ上で動作するランサムウェアをAIで作って配布するのは大変難しく1、実際の行使はできていないと考えられ、今回は作成罪が適用されたわけですが、安易な適用には(萎縮効果なども考えられ)懸念を持たざるを得ない。(意図を持って作成すれば作成罪が適用できるが、意図の立証は難しく、立件するのは難しい。今回は特殊なケースとも考えられる。)

また、生成AIによって不適切なコンテンツ(例:ヌード画像、犯罪に使えるような情報)やフェイクニュースが作られるという問題も指摘されました。

前者に関しては、生成AIにはこうした「不適切な」コンテンツを教えなければ良いではないかという指摘もありますが、

「不適切な」アプトプットを制御するには「不適切な」こと自体が教えられていなければならず、教えないという手段は難しいと考えられます。 有用なことをさせるには、アウトプットはして欲しくないことも教えなければならないこともある。 例:人体をうまく描くためには、ヌードモデルを人でも機械でも学習する必要がある。

といったこともあり、教えないのは難しいと考えられます。従って、これらの「しつけ」はプロンプトレベルで基本行われることになります。しかし、オープンなAIモデルではその強制が難しく、悪用される可能性があります。生成AIの活用と規制のバランスが課題となっています。マルウェアや不適切なコンテンツが生成AIによって大量に産み出されることは前提として受け止めざるをえず、対策もAIによって行われる必要があると考えられます。AI使用に関する規制と倫理的ガイドラインの必要性に関する議論を深めることが求められます。

クラウドシフトの影響

クラウドシフトが進む中で、クラウドベンダー管理が難しくなっています。コスト削減のメリットや、短期的なセキュリティ強化のメリットはあるものの、ベンダーの実態把握が困難になり、リスクの見積りが難しくなることのほか、クラウドプロバイダーへの過度の依存の長期的リスクとして、内部専門知識の維持が難しくなること、クラウドサプライチェーンのリスク、価格値上げのリスクなども指摘されていました。

一方で、クラウドベンダーは監査に基づく第三者認証の取得や情報公開を行い、安全性を担保する努力をしています。認証制度にはISMSやSOC2、官公庁向けのものとしては米政府のFedRAMPや日本政府のISMAPなどがあります。もっとも、こうした認証取得(特にSOC2やISMAP)は多大な費用がかかり、中小プロバイダには対処が難しいという問題も指摘されました。これに対して、調達側は、中小が対応できていない部分に関しては、調達側がそこを補う2ことによってカバーしようともしていることも紹介されました。

また、インシデント発生時の情報開示を求められた場合、クラウドベンダーがどの程度の情報を開示できるのかということには注意が必要であることも指摘されました。監査証跡や第三者による監査レポートなどを提示することはできますが、個別のお客様のデータを切り分けて開示することは技術的に困難である可能性があります。完全な情報開示には限界があるかもしれません。

採用する組織は、こうしたことも考え合わせた上で、クラウドシフトのメリットとデメリットを見極める必要があります。

大規模ランサムウェア事件と対策

最近、大規模なランサムウェア事件が続いています。これらはランダムな攻撃から、標的を絞った高価値の操作へのシフトしてきており、洗練度の向上と影響の大規模化が指摘されます。例えば、コロニアルパイプラインの事件3に象徴される重要インフラへの影響などが挙げられますし、直近ではK社4とI社5の例が挙げられます。

これらは複数の意味で被害のフェーズが変わったということも言えます。

まず第一に被害の金額がとても大きくなっています。

次に、その人の人生を生死も含め左右してしまう的な意味、例えば、極寒の地でエネルギー供給が止まれば即凍死の危険があるし、タレントの住所がわかってしまうことでストーカー殺人に至る可能性もある6

また、社会的信用メカニズムの毀損という意味で、I社の事例は影響が大きいです。I社の事例は、ISMSやPマークを持つ企業で監査もきちんと受けており、ネットワークも基本分離していたにも関わらず、情報が盗まれることになりました。これは、業務系のネットワークにしかないはずの情報が、情報系のネットワークにコピーされその辺に転がっていたり、自治体に対して削除証明を出していたデータが実際には削除されていなかったりということに起因しています。認証制度はこれを見つけることができなかったわけで、認証制度への信頼性の低下という社会的インパクトを持つ、というようなことが指摘されました。

一方で、ISMSなどの認証制度に関しては、

ともすればチェックリスト的になるが、それは本質ではなく、経営者のリーダーシップとリスク認識が重要; 認証取得自体が目的化してはいけない; 特定の業務に特化した認証制度が必要で、認証制度の役割と限界を理解し、より実効性のある対策が求められている;

ということなども指摘されていました。

また、このセクションでは、インシデント発生時の情報開示の在り方や、委託先管理の重要性が指摘されました。ランサムウェア対策として、モニタリングの強化や、マネジメントシステムの見直しが必要不可欠であることも指摘されました。

こんにちは、富士榮です。

ようやく折り返しましたが引き続きW3C Verifiable Credentials Overviewを読んでいきます。


Introduction Ecosystem Overview Verifiable Credentials Data Model Securing Credentials Bitstring Status List Additional Publications

今回も引き続き4番目のSecuring Credentialsを見ていきます。

前回はEnvelop proof(JWS)だったので、今回はEmbedded Proof(VC Data Integrity)を見ていきます。

2. Embedded Proofs 2.1. Generic Data Integrity Structure

The operation of Data Integrity is conceptually simple. To create a cryptographic proof, the following steps are performed: 1) Transformation, 2) Hashing, and 3) Proof Generation.

データ完全性の操作は概念的には単純です。暗号証明を作成するには、次のステップを実行します。1) 変換、2) ハッシュ化、3) 証明生成。

図7. Generic view of the proof generation steps.
Data Integrity Proofの作成は変換、ハッシュを行った上でProofを作成する、という流れということです。続いて各ステップについて解説がされています。

Transformation is a process described by a transformation algorithm that takes input data and prepares it for the hashing process. In the case of data serialized in JSON this transformation includes the removal of all the artifacts that do not influence the semantics of the data like spaces, new lines, the order of JSON names, etc. (a step often referred to as canonicalization). In some cases the transformation may be more involved. Hashing is a process described by a hashing algorithm that calculates an identifier for the transformed data using a cryptographic hash function. Typically, the size of the resulting hash is smaller than the data, which makes it more suitable for complex cryptographic functions like digital signatures. Proof Generation is a process described by a proof method that calculates a value that protects the integrity of the input data from modification or otherwise proves a certain desired threshold of trust. A typical example is the application of a cryptographic signature using asymmetric keys, yielding the signature of the data.

変換とは、入力データを受け取り、ハッシュ化処理の準備をする変換アルゴリズムによって記述されるプロセスです。JSONでシリアライズされたデータの場合、変換には、スペース、改行、JSON名の順序など、データの意味に影響を与えないアーティファクトの除去が含まれます(正規化と呼ばれるステップ)。場合によっては、変換はより複雑になることがあります。 ハッシュ化は、暗号ハッシュ関数を使用して変換されたデータの識別子を計算するハッシュアルゴリズムによって記述されるプロセスです。通常、生成されたハッシュのサイズはデータよりも小さいため、デジタル署名のような複雑な暗号機能に適しています。 証明生成とは、証明方法によって記述されるプロセスであり、入力データの整合性を改ざんから保護する値、または特定の信頼性基準を満たすことを証明する値を計算します。典型的な例として、非対称鍵を使用した暗号署名アプリケーションがあり、これによりデータの署名が生成されます。

このTransformにおける正規化(Canonicalization)がしばしば問題視されるところですね。

以前SAMLの脆弱性についてこのブログでも取り上げましたが、実際にシリアライズを正しく安全に行う、というのは難しいところです。OpenID Connectの設計思想としてIdentiverseでも取り上げられていたのはまさに「No canonicalization」でした。SAMLでの苦い思い出から正規化をせずにクレデンシャルを表現できる方式としてJWSを採用したわけです。

Verification of a proof involves repeating the same steps on the verifier's side and, depending on the proof method, validating the newly calculated proof value with the one associated with the data. In the case of a digital signature, this test usually means comparing the calculated signature value with the one which is embedded in the data.

証明の検証には、検証者側で同じ手順を繰り返す必要があり、証明方法によっては、新たに計算された証明値をデータに関連付けられた値で検証します。デジタル署名の場合、このテストは通常、計算された署名値とデータに埋め込まれた署名値を比較することを意味します。
2.2. VC Data Integrity

The Verifiable Credential Data Integrity 1.0 [VC-DATA-INTEGRITY] specification relies on the general structure and defines a set of standard properties describing the details of the proof generation process. The specific details (canonicalization algorithm, hash and/or proof method algorithms, etc.) are defined by separate cryptosuites. The Working Group has defined a number of such cryptosuites as separate specifications, see 4.2.3 Cryptosuites below.

The core property, in the general structure, is proof. This property embeds a claim in the Credential, referring to a separate collection of claims (referred to as a Proof Graph) detailing all the claims about the proof itself:

 検証可能な資格情報データ完全性 1.0 [VC-DATA-INTEGRITY] 仕様は、一般的な構造に依存し、証明生成プロセスの詳細を説明する一連の標準プロパティを定義します。具体的な詳細(正規化アルゴリズム、ハッシュおよび/または証明方法アルゴリズムなど)は、別の暗号スイートによって定義されます。ワーキンググループは、このような暗号スイートを別個の仕様として多数定義しています。詳細は、以下の4.2.3 暗号スイートを参照してください。

一般的な構造におけるコアとなる特性は「証明」です。この特性は、クレデンシャルにクレームを埋め込み、証明自体に関するすべてのクレームを詳細に説明する別個のクレーム集合(証明グラフと呼ばれる)を参照します。

VC Data Integrityの使用は別途策定されていますが、まだW3C勧告とはなっておらずCR(Candidate Recommendation)の状態です。

EXAMPLE 8: Skeleton of a proof added to a Credential { "@context": [ "https://www.w3.org/ns/credentials/v2", "https://www.example.org/vocabs/alumni" ], "id": "https://university.example/Credential123", "type": ["VerifiableCredential", "ExampleAlumniCredential"], "issuer": "did:example:2g55q912ec3476eba2l9812ecbfe", "validFrom": "2010-01-01T00:00:00Z", "credentialSubject": { "id": "https://www.example.org/persons/pat", "name": "Pat", "alumniOf": { "id": "did:example:c276e12ec21ebfeb1f712ebc6f1", "name": "Example University" } }, "credentialSchema": { "id": "https://university.example/Credential123-schema-credential", "type": "JsonSchemaCredential" }, "proof": { "type": "DataIntegrityProof", … // All the details about the proof … "proofValue": "zQeVb…Wx" } }

Note the proofValue property, whose object is the result of the proof generation process.

proofValue プロパティに注目してください。このプロパティのオブジェクトは、証明生成プロセスの結果です。 

NOTE

The proof value is for illustrative purposes only, and does not reflect the result of real cryptographic calculations.

実際のサンプルが示されています。proofのtypeに"DataIntegrityProof”、そしてvalueのところに計算された値が入ることになります。

The definition of proof introduces a number of additional properties. Some of these are metadata properties on the proof itself, like created, expires, or domain. Others provide the necessary details on the proof generation process itself, like cryptosuite, nonce (if needed), or verificationMethod that usually refers to cryptographic keys. The exact format of the public keys, when used for Credentials, is defined in the [CONTROLLER-DOCUMENT] specification, and is based on either the JWK [RFC7517] format or a Multibase [MULTIBASE] encoding of the keys, called Multikey. Details of the key values are defined by other communities (IETF, cryptography groups, etc.) and are dependent on the specific cryptographic functions they operate with.

It is possible to embed several proofs for the same Credential. These may be a set of independent proofs (based, for example, on different cryptosuites, to accommodate to the specificities of different verifiers), but may also be a "chain" of proofs that must be evaluated in a given order.

A proof may also specify its "purpose" via the proofPurpose property: different proofs may be provided for authentication, for assertion, or for key agreement protocols. These possible purposes are defined in the [CONTROLLER-DOCUMENT] specification. The verifier is supposed to choose the right proof depending on the purpose of its own operations, which is yet another possible reasons why the holder or the issuer may provide several proofs for the same Credential.

 証明の定義には、いくつかの追加プロパティが含まれます。その中には、証明自体のメタデータプロパティ(作成日、有効期限、ドメインなど)もあります。また、証明生成プロセス自体の詳細を提供するプロパティもあります(cryptosuite、nonce(必要な場合)、通常、暗号鍵を指す verificationMethod など)。クレデンシャルに使用される公開鍵の正確なフォーマットは、[CONTROLLER-DOCUMENT] 仕様で定義されており、JWK [RFC7517] フォーマットまたは Multikey と呼ばれる公開鍵の Multibase [MULTIBASE] エンコーディングのいずれかに基づいています。鍵値の詳細は、他のコミュニティ(IETF、暗号グループなど)によって定義されており、使用する特定の暗号機能に依存します。

同じクレデンシャルに対して複数の証明を埋め込むことが可能です。これらは独立した証明のセット(例えば、異なる検証者の特殊性に対応するために異なる暗号スイートに基づく)の場合もありますが、所定の順序で評価しなければならない証明の「チェーン」の場合もあります。

証明は、proofPurposeプロパティを通じてその「目的」を指定することもできます。異なる証明は、認証、アサーション、または鍵合意プロトコル用に提供されます。これらの可能な目的は、[CONTROLLER-DOCUMENT]仕様で定義されています。検証者は、自身の操作の目的に応じて適切な証明を選択することが想定されています。これが、同じクレデンシャルに対して複数の証明を提供する理由の1つです。

Data Integrityの特徴で便利だと思うのは複数のProofを埋め込むことができる点、そして目的を指定することができる点です。例えば、学修歴など複数の教員によって証明されることがあるクレデンシャルについてはこの機能は有用なのかもしれません。


長くなってきたので、続きのCryptosuiteからは次回に送りたいと思います。



Wrench in the Gears

The Undivided Universe of the Heart

That little voice whispered it was time to get out of the apartment and clear my head. I’d been working on additions to a map for several days, and it was going slower than I wanted it to go. My mother, in her 80s, moved into assisted living last month. As is to be expected, [...]

That little voice whispered it was time to get out of the apartment and clear my head. I’d been working on additions to a map for several days, and it was going slower than I wanted it to go. My mother, in her 80s, moved into assisted living last month. As is to be expected, all the changes have been difficult for her. Compounding that, our communication lines seem to be experiencing a lot of psychic static; an ongoing family curse. So I’m trying to navigate that even as my own circumstances are still unsettled, at least for another month. 

How does one undertake the responsibilities of a good daughter, when for some reason the gate to a mother’s heart continues to malfunction? Can you insert yourself into someone’s life if all signs indicate you’re not really welcome? Maybe not yet. Maybe things have to get worse before resolution is possible. When does the child take on the role of the mother? It doesn’t feel like a role that can be stepped into gracefully. Plus, I don’t have anyone physically here in my corner to lean on, which is not what I expected at this stage of the game. I guess I should see it as an opportunity to exercise my self-reliance muscles. 

Despite offers of assistance, none were warmly welcomed. So I’m left with a lot of question marks. I send flowers and prayers across several thousand miles and try to come to terms with my situation. A friend found a small medallion in a parking lot with the inscription “Family Is Everything” only to later realize that it was a Disney branded trinket, which put a new spin on the pithy trope. No, not everything. 

Every family comes with its own lessons, and oh those morphogenetic fields can be a bear. Perhaps the best thing is to offer what you can with an open, tender, and decidedly imperfect heart and let the pieces fall where they may. I think we do this more than once. Maybe my mother and I have done it a hundred times already. Maybe this round I fared better than in the last one, and in the next I’ll make more progress. It’s the journey, right? Not the destination…

So I drove across town to my rented PO box to pick up a book and some linen fabric I’d treated myself to. The colors are gray cashmere and Montana grape, which will make a lovely skirt and blouse for fall. I’m looking forward to pulling out my sewing machine and embroidery floss again. The purchase, which was spurred on by an emailed discount code, was my way of staking a claim on that future. The book was Bohm and Hiley’s “The Undivided Universe.” 

Impatient and curious, I flipped through the pages on quantum consciousness in the parking lot as I placed the packages in the trunk and blanched at the equations therein. I really am hopeless with math and physics, but hopefully I can glean some insights on active information and the meaning of our oneness. As much as my mother exasperates me, I love her and I suspect she loves me too, just as I love my prodigal child. The signals are choppy – entangled human weather in the swirling gyre.

My inner voice said take the growing collection of feathers on the shelf above the desk here in the apartment. There is a strange giant gold hand with some books around it that clearly came from the decorator, books by the yard, not ones that were actually ever read by anyone. In the hand I’d placed a sprig of mistletoe that fell out onto the windshield of my car from the towering willow oaks that line the street where I’m staying. I have a small pile of stones, pinecones, and other bits and bobs. I put most of the feathers and a few of the stones in a soul-bright yellow canvas bag my friend Juliana entrusted to me during our Lititz foray. I decided on my way back I’d stop at “Space Odyssey” Allsopp Park and make a heartfelt intention for my mom during this time of her bumpy transition.

I think my hearts confound some people. They don’t know how to integrate the Alison that makes maps about inscrutable things with the Alison who walks around making patterns with acorns and leaves. I think some people think I ought to be embarrassed, perhaps not that I make them, but that I share them publicly. 

Even though I used to consider myself a progressive, I began to see that I’m really more spiritually-minded than materialist inclined. I have my reasons for being skeptical of institutional faith communities, but I do feel the pull towards a benevolent creator. The gift of sacred cyclical beauty in nature is part of that. A woman on Facebook inspired my hearts. She posted photos spelling out “love” in sticks and stones. During that terrible period of the lockdowns, it felt like a meaningful affirmation and it still does. 

If there is an implicate order, why not seek to communicate with it? For me, making hearts is like a guided meditation. I’m not a good meditator in the regular sense. My wheelhouse is symbol and story. For me, the practice works, and I share it, because it may work for other people too. Someone gifted me a version of their prayer, and I made it my own, and so may it be for others if it makes sense in your life. If not, feel free to immerse yourself in my maps instead. They are both valuable sides of the complex pattern that is Alison McDowell this time around.

I was still working at the garden during Covid, so I had ample materials to work with. Eventually, I decided laying out a heart shape was preferable to using words. Ever since I’ve made 3-4 hearts a month with nature’s findings. Sometimes I do it to neutralize fraught energy in a place I’ve researched, but not always. Sometimes I simply do it as a way to reaffirm my place in the world. With each I offer an intention for “life, health, and open paths” that Cliff Gomes taught me. 

At first I hoarded materials, thinking that was what was needed; but with time, I realized the gift of a public heart is a reflection of a given place. Rather than bringing new materials to a spot, it was better to seek out the message from the location itself. What communication awaits? The trickiest part of heart-making is finding materials to outline the shape. From there, you can decorate inside and outside with a smattering of this or that. 

When I got out of the car with my little yellow sack, I first saw a bountiful native pollinator garden full of sunflowers and bee balm and ironweed, a towering presence with deep purple flowers that I remember standing guard over the lower garden in high summer. I didn’t pick any of them though. The bees and wasps were enjoying them too much. I turned to head down the path and saw a giant wild wisteria vine clambering into a tree. The blossoms were spent, but there were a dozen or so soft, green velvet seed pods. That’s what I picked for the outline of today’s heart. 

Wisteria is named for the Wistar family of Philadelphia, peers of John Bartram, glass makers, and doctors. In the late nineteenth-century the Wistar Institute, which is located on the campus of the University of Pennsylvania, became one of the first biomedical research labs in the world with a focus on vaccines. The first standardized experimental lab rat was created there, the Wistar rat. 

Next, some ferny wild carrot tops caught my eye. I didn’t harvest any, but a wave of remembrance came over me for the summers of my childhood where I played in the dirt lots and tree lines of corporate suburbs in the making. Those summers in the late 1970s and early 1980s where carrot beings anchored themselves into the imaginative world building exercises of feral youth. Even as my adult world has fallen apart, that broken-ness gifted me the chance to renew my connection with the younger version of Alison, the one who would jump the fence onto a neighboring farm to walk the creek and pretend she lived in Narnia.

I left the pavement and took the high route up the wooded hillside. At the bottom I scooped up a few small pieces of bark from a fallen branch that was coated with a bluish-green lichen, still damp from the thunderstorm that rolled in this morning after weeks of dry heat. The storm knocked the dust down and you could still smell the earthiness of the soil. 

The walk up was uneven and rocky. “We are shapes of the Earth” as John (or Tina) Trudell would say. Their refrain came to me as my sandals found footing among the loose stones. A few slices found their way into my bag, including a shard pierced by a round hole the size of a quarter. The path affirmed our mineral connection. Gray slate of ancient sea beds pitched vertically with cataclysmic force; the sheets splayed out like a library of plundered books with bindings broken, quires unmoored. The consciousness of those stones spoke my language of order lost to chaos, but with elegance and meaning, undertones of their present disheveled arrangement. 

At the top of the hill was a signpost. I took a turn to the right and followed along the edge of a small ravine to where the Nandina grew. I thought about the Hot Springs park ranger berating the shrub for being an interloper, but it has a special place in my heart. After I left home, my parents moved into a house with an elaborately landscaped yard. There was a hedge of Nandina and I dug up a sprout and brought it home with me to Philadelphia where it flourished in our small patio garden. I would have to cut it back pretty vigorously every year and it never flowered like it did in the South, but it reminded me of my dad, so of course I grabbed a sprig and put it on the bag.

I also saw three purple mist flowers, blue boneset. I love purple, so I put them in, too. There were also huge stands of poke on the other side of the path. Their flower panicles were in just the early stages of white and green, before the intense purple berries arrive. The white, pink, and green pokeweed always reminds me of the preppy era when pink and green attire was all the rage in middle school. 

During my walk, the woods were infused with R&B music from a distant picnic pavilion. When I pulled into the parking lot, I noticed a white pick-up truck towing a huge barbeque grill. There were a bunch of families having a cookout, which made me think about the big gatherings you see on summer weekends in Fairmount Park. It made me a tiny bit homesick, but in a good way.

When I used to live near John Coltrane’s Philadelphia house on 33rd Street, they had papers in the windows with the saying “one thought can create millions of vibrations and they all go back to God.” So, I go into nature with questions and an inner knowing that on the other side at least it will be ok; we will all be ok. 

I can make an offering to try and harmonize the present moment of uncertainty. It may look like a milky quartz stone surrounded by lichen and feathers and pinecones and wisteria pods with a smattering of purple, because that’s what I like. That’s what little Ally liked, too. And we can weave a story of love even if the creaky lock is stuck, because one day it will open. The vibrations are slipping under the threshold and loosening the resistance. The path is open. We just need to find our way to the trailhead. 

I’m not a nihilist. I’m studying the quantum and ontopoesis and the participatory universe, because I know that love finds a way. Meg knew that. Patience isn’t my strong suit, but this journey may carry across dimensions and I have to learn to endure and cultivate a sense of humor in the absurdity of it all. 

Spoiler alert – love wins! 

PS: I didn’t take my camera with me, so this heart will just have to live in your imagination.

ニュージーランドのデジタルID規制機関が始動

こんにちは、富士榮です。 少し前のニュースですがニュージーランドで今月からデジタルIDに関する規制を行う機関(要は認定機関)である「Trust Framework Authority」の活動が開始されているようです。 ニュースソース https://www.biometricupdate.com/202407/new-zealand-digital-identity-regulator-opens-doors-ushering-in-era-of-digital-id Trust Framework Authority(ニュージーランド政府のページ) https://www.digital.govt.nz/standards-and-guidance/identity/trust-framework/trust-framework-authority/ 認定

こんにちは、富士榮です。


少し前のニュースですがニュージーランドで今月からデジタルIDに関する規制を行う機関(要は認定機関)である「Trust Framework Authority」の活動が開始されているようです。

ニュースソース

https://www.biometricupdate.com/202407/new-zealand-digital-identity-regulator-opens-doors-ushering-in-era-of-digital-id

Trust Framework Authority(ニュージーランド政府のページ)

https://www.digital.govt.nz/standards-and-guidance/identity/trust-framework/trust-framework-authority/


認定を受けるとこんなマークが発行されるみたいですね。


導入の背景として行政サービス等のデジタル化があるようです。日本を含む他の国々と同じく、身分証明書のデジタル化(スマホ搭載等)によりオンラインでの身元確認ができるように、という話ですね。mDL(モバイル運転免許証)の導入も視野に入っているようです。

実際、日本においても身元確認書類(例えば免許証やマイナンバーカード)をスマホに搭載する話が進んでいますし、先日AppleもWalletにマイナンバーカードを搭載できるようにする、という発表が行われましたが、EUが一歩先でやっているように政府機関がある程度Walletプロバイダやサービスを認定できる状態にしておかないと、勝手にマイナンバーカードの券面読み取りAPIなどを使って「マイナンバーカードのコピー」をスマホに搭載してあたかも「公的な身分証明書」のように誤認されてしまう状態が大量に出来上がる、ということが懸念されます。(個人的な意見ですが)

そういう意味ではこのような認定機関をちゃんと作って運営をしていくことが日本にも求められてくると思います。


Trust Framework Authorityのページを見るとこの機関の責任は以下のように定義されています。

機関の責任 プロバイダーを認定する 認定プロバイダーが信頼フレームワークの法律、規則、規制を常に遵守していることを確認する 認定された提供者またはサービスに関する苦情を評価し、調査する デジタル ID サービス信頼フレームワークの認定マークを管理する


まだ7月1日に走り始めたばかりで公開されている情報も少ないですが少し追いかけてみたいと思います。

The America I love

I’m a natural-born American citizen but never lived here until my early thirties. I have a complicated relationship with the country: I never thought I’d live here until I suddenly did. As it happened, my parents moved back to look after my grandmother, and ten years later, I came here to look after my mother. I was 21 when Bush became President, having been the state governor who had executed

I’m a natural-born American citizen but never lived here until my early thirties. I have a complicated relationship with the country: I never thought I’d live here until I suddenly did. As it happened, my parents moved back to look after my grandmother, and ten years later, I came here to look after my mother. I was 21 when Bush became President, having been the state governor who had executed the most people; I marched against the Iraq War from Scotland. There was never a moment where I thought, “America is a place I want to live.” But I wound up here anywhere.

The America I had no intention of being a part of is still very much here. It’s the America where people love guns and the right own semi-automatic weapons is more important than the idea that we need to stop children from being slaughtered in their schools. It’s the America where the state murders prisoners by electrocuting them or injecting them with poison or by gassing them, and where the police can gun down a person of color and walk away. It’s the America that organizes coups in other countries to further its own interests and nobody sees anything wrong with it because it keeps gas prices down. It’s the America that won’t take the bus because that’s what poor people do (and the word “poor” is doing a lot of work here). It’s rugged individualism and wealth-hoarding over community inclusion and equity. It’s racial stereotypes and old-fashioned values. It’s flag-waving. It’s Bill O’Reilly and Pat Buchanan and George W Bush and Donald Trump.

I’m sorry, but I can’t bring myself to love that America. It’s a bad place to live. Objectively, even.

But that isn’t the only America. It turns out there are lots of them: not just in the sense that each state is its own mini-nation, although that’s true too, but also in terms of layers that spread from coast to coast.

There’s an America I’m delighted to be a part of; one that I’ve come to truly love. It’s the America that understands the impact it’s had and has, both on its own communities and on the world, and genuinely wants to do much better. It’s an America that is anti-drone, anti-war, and against the military-industrial complex. It’s the America that wants to spread equity and uplift communities instead of individuals. It’s the one where nobody would ever think of banning a book or a news source, where public libraries are for everyone, where it’s commonly understood that education should be free and for all. It’s the one that loves art and literature, that provides platforms for diverse lived experiences, that believes in reparations. It loves people of all religions, and no religion, equally, and knows that the separation of church and state is a vital tenet for an inclusive democracy. It believes in democracy, come to that, and science, and data and experimentation. It believes in the common public good and in social contracts. It preserves nature and protects vulnerable communities and makes sure nobody falls through the cracks. It fights fascism of all kinds, from the loud politicians who seeks to turn the country into a theocracy to the small voices who shun difference in their local communities. It believes that immigration makes the country great, and it invites people to join as is without needing to assimilate or dissolve into a melting pot. It believes that everyone should have the right to marry whoever they choose, have the right to do what they will with their own bodies, and assert their identities however they need to. It doesn’t care how much money you make, where you come from, or what you believe: it asserts that you deserve to live well. It is inclusive, and welcoming, and beautiful. It’s Noam Chomsky and bell hooks and Alexandria Ocasio-Cortez and Daniel Ellsberg and Chelsea Manning. It takes the damn bus.

I assure you that it exists, and it’s everywhere. I’ve traveled across this country many times now, and there are pockets of this America in the places you’d least expect, alongside the places where you would expect it. There are people trying to make a better country, a more progressive and inclusive country, everywhere you go.

It’s not the only America, and it’s not the loudest America. But it’s the best one, by far. I think it’s worth saying that I do love it; I want to support it; I want it to be the defining experience of being in and from this country. I don’t think that’s inevitable, but I think, if we all work at it, that it as every chance of happening. I would love that to be the case.

Blockchain Badges and TikTok School Choice Deep In The Heart of Texas

This three-hour chat with my friend Lynn Davenport of Dallas, Texas was initially triggered by my frustration with a recent RFK Jr. video promoting blockchain as the future.   While I wanted to deconstruct the silly nationalist tone of his video, promoters of decentralized ledger tech know that the whole point is peer-to-peer communication and [...]

This three-hour chat with my friend Lynn Davenport of Dallas, Texas was initially triggered by my frustration with a recent RFK Jr. video promoting blockchain as the future.

 

Video: https://www.youtube.com/watch?v=EmGyGEyDOPc

While I wanted to deconstruct the silly nationalist tone of his video, promoters of decentralized ledger tech know that the whole point is peer-to-peer communication and borderless payment processing, we ended up having a much deeper conversation with many updates around education policy in the Lone Star state, including Open Education Resources (see our playlist of videos on that topic here) and manufactured culture wars that are serving as a major distraction from getting people up to speed on the ethical implications of linking AI to hive mind, swarm intelligence protocol layers in the name of radical democracy.

I know most people are not going to make time to listen to the whole thing, so I pulled two short teaser clips. One is about the OER being blockchain badges, not Bible-study paper print outs as some Texas representatives would have you believe. The other is my frustration over the Diane Ravitch / Badass Teachers Association brain boxing and the perils of manufactured heroes and structured teaming. I am indebted to both, however, for giving me the eyes to see the role of RFK Jr. and health freeDOM influencers in steering consciousness and sheep dogging folks into the box canyon of Web3 quantified self wearables and wellness key performance indictors. 

Today is Red White and Blue day – if you celebrate, please remember the superorganism has no flag! It’s time to get serious folks. Step away from your assigned team and start thinking for yourself.

Teaser #1: OER is about blockchain badges and digital ID. 2 Minutes

The Pulse #99: Relational databases here to stay as good fits for AI?

Also: $415M not enough for founders to stay at startup; France targeting NVIDIA with antitrust; a standout dev tools success story at GitLab, and more.

The Pulse is a series covering insights, patterns, and trends within Big Tech and startups. Notice an interesting event or trend? Send me a message.

Happy 4th of July to US readers; I hope you enjoy the long weekend. I’m taking a half-holiday here in Amsterdam, as my wife’s American. For that reason, it’s a shorter than usual edition of The Pulse, today. The full-length version returns next week!

In this issue, we cover:

Relational databases here to stay as good fits for AI?

$415M not enough for founders to stay at startup

France targets NVIDIA with antitrust regulation

Microsoft insiders don’t want to be “IT for OpenAI”

Figma to train on paying customers’ data by default

More job cuts at Microsoft

A standout dev tools success story: GitLab

Industry pulse Relational databases here to stay as good fits for AI?

With the rise of large language models (LLMs,) vector database solutions are more relevant than before because embeddings are at the core of LLMs. An embedding is a vector that is a multi-dimensional representation of a token (basically a piece of text, image, or similar.) Operations like retrieval augmented generation (RAG) calculate the embedding of the input, and try to find previously stored embeddings (chunks of texts) in a vector database, so these vector databases are now very useful. We previously covered RAGs in more detail.

Lots of venture capital has flowed into vector database startups, with Pinecone one of the best-known cases, along with Chroma, Weaviate, and others.

The paper “What goes around comes around… and around,” was authored by Michael Stonebraker — who is a computer scientist (and currently a professor at MIT) with decades of experience in database systems: the cofounder of Ingres, Vertica and VoltDB, and the recipient of the 2014 Turing Award — and Andrew Pavlo — the cofounder of AI-powered SQL optimization startup, Ottertune, and an associate professor at Carnegie Mellon university. They analyzed the evolution of database management systems, and interestingly concluded that relational database management systems add vector support surprisingly rapidly, and that vector database systems must become more relational in order to stay competitive:

“After LLMs became “mainstream” with ChatGPT in late 2022, it took less than one year for several RDBMSs to add their own vector search extensions. In 2023, many of the major RDBMSs added vector indexes, including Oracle, SingleStore, Rockset, and Clickhouse.

There are two likely explanations for the quick proliferation of vector indexes. The first is that similarity search via embeddings is such a compelling use case that every DBMS vendor rushed out their version and announced it immediately. The second is that the engineering effort to introduce a new index data structure is small enough that it did not take that much work for the DBMS vendors to add vector search. Most of them did not write their vector index from scratch and instead integrated an open-source library (e.g., pgVector, DiskANN, FAISS).

We anticipate that vector DBMSs will undergo the same evolution as document DBMSs by adding features to become more relational-like (e.g., SQL, transactions, extensibility). Meanwhile, relational incumbents will have added vector indexes to their already long list of features and moved on to the next emerging trend.”

The paper is worth reading, and makes the compelling case backed by data that relational databases are here to stay. Their takeaway (emphasis mine):

“We predict that what goes around with databases will continue to come around in the coming decades. Another wave of developers will claim that SQL and the relational model (RM) are insufficient for emerging application domains. People will then propose new query languages and data models to overcome these problems. There is tremendous value in exploring new ideas and concepts for DBMSs (it is where we get new features for SQL.) The database research community and marketplace are more robust because of it. 

However, we do not expect these new data models to supplant the relational model.”

I agree that SQL providers seem like a safe bet for the majority of computing tasks, including working with embeddings and vectors. Obviously, if there’s huge amounts of data or extremely specialized use cases, do some research and potentially use a different tool. Still, relational stores like PostgreSQL and MySQL have shown themselves to scale surprisingly well.

Thank you to this post on X by Jaromir Hamala, engineer at QuestDB, that surfaced this observation.

Thank you to Dan Goldin for pointing out that important and relevant context on Michael Stonebraker was missing originally.

It took me a long time to get through the first third of this novel. The protagonist is so vapid, her point of view so incurious and at the same time so familiarly American, against a backdrop of obvious imperialism and climate obliviousness, that it was hard to find the motivation to continue.

But I’m glad I did. This is an indictment of one character, but through her, all of America, and every country and every person that touches the interconnected hyperobject of energy, climate, and western prosperity. It’s savage, witty, and remarkably pointed: the kind of book that’s soothing to read in the modern age because no, you’re not alone, someone else is feeling this too, and their rage has manifested into something far better articulated than you could hope to muster.

Is this shared awareness enough to halt the catastrophe that we’re careening towards? Probably not. But holy shit, there’s something here, and if there’s even a chance we can pull off the total culture change that averting this crisis requires, we need to try.

The remaining two thirds sharpen to a point, an ending that will cut you without mercy. And I’m grateful for it.

I’ve spent the week in Florence, Oregon, a lovely little town on the coast. It’s a bit windy and a little cold, but as I’m fond of saying, I lived in Scotland for a decade. I can take it.

Frank Herbert came to the town in 1957 to write about the dunes overtaking it. The piece was never published, but it gave him an idea for a novel.

In 1970, a whale washed ashore here, and the Oregon State Highway Division decided to use dynamite to dislodge it. The ensuing events were not quite as planned. If you’ve never seen it, the video is legendary.

Did you know that Dune and the exploding whale beach were the same place? Well, now you do.

"To help preserve a safe Internet for content creators, we’ve just launched a brand new “easy button” to block all AI bots. It’s available for all customers, including those on our free tier."

This is really neat! Whatever you land on AI scraping, giving site owners the one-click ability to make a choice is great. Some will choose not to use this; others will hit the button. Making it this easy means it's a choice about the principles, not any kind of technical considerations. Which is what it should be.

Not every site is on Cloudflare (and some also choose not to use it because of how it's historically dealt with white supremacist / Nazi content). But many are, and this makes it easy for them. Other, similar providers will likely follow quickly.

EUの新アンチマネロン法パッケージ:概要と影響

おはようございます。第28回サイバー犯罪に関する白浜シンポジウムに向かう崎村です。 シリーズ第一回、第二回では、今回の改正に至る背景にあった文書について見てきましたが、今回はいよいよ本丸の法改正についてです。 概要 2024年6月19日、EUは、以下から構成される「AMLパッケー…

おはようございます。第28回サイバー犯罪に関する白浜シンポジウムに向かう崎村です。

シリーズ第一回、第二回では、今回の改正に至る背景にあった文書について見てきましたが、今回はいよいよ本丸の法改正についてです。

概要

2024年6月19日、EUは、以下から構成される「AMLパッケージ」をEU官報で公表しました。この法律パッケージは以下から構成されています:

マネーロンダリング及びテロ資金供与対策機関(AMLA)を設立する規則(EU)2024/16201(AMLAR)。 フランクフルトを拠点とする、新しい欧州マネーロンダリング及びテロ資金供与対策機関(AMLA)の設立。この規則は公表から7日後に発効し、2025年7月1日から適用されます。 マネーロンダリング又はテロ資金供与のための金融システムの使用を防止する規則(EU)2024/1624(AMLR)2 EU全体でAMLルールを統一し、不正行為者の抜け道を塞ぐ新しい規則。この規則は公表から21日後に発効し、2027年7月10日から適用されます(ただし、サッカーエージェントおよびプロサッカークラブの一部の取引については2029年7月10日から適用)。 マネーロンダリング又はテロ資金供与のための金融システムの使用を防止するために加盟国が実施すべき仕組みに関する指令(EU)2024/1640(AMLD 6)3 この指令は指令(EU)2019/1937を改正し、指令(EU)2015/849を改正及び廃止するものです。国内AMLシステムの組織化と、金融情報機関(FIU)および監督機関間の協力を改善する指令。この指令は公表から21日後に発効します。加盟国は2025年7月10日までにこの指令を国内法に置き換える義務があります。

これらの要件は段階的に施行され、新しい規制環境に合わせて内部手続きを調整することが可能になります。

マネーロンダリング及びテロ資金供与対策機関(AMLA) AMLAはドイツのフランクフルトに本部を置き、以下の役割を果たします: 少なくとも6つの加盟国で事業を行う信用機関および金融機関の定期的な評価を実施し、高リスク事業体を直接または間接的に監督 拘束力のある決定を下し、非遵守に対して行政罰および金銭罰を課す権限を持つ 国内監督当局のアプローチを調整し、ガイドラインを発行 マネーロンダリング又はテロ資金供与のための金融システムの使用を防止する規則(AMLR)

AMLRは、以下を導入しています。

暗号資産セクター、高級品取引業者、サッカークラブなど、新たな義務対象事業体4にAMLルールを拡大適用 より厳格なデューデリジェンス要件の設定、実質的所有者の規制、現金支払いの1万ユーロへの制限。 金融セクターにおける高リスクの義務対象事業体に対し、AMLAに直接的および間接的な監督権限を付与 AML要件の重大、系統的、または反復的な違反に対し、AMLAに制裁を課す権限を付与

また、義務対象事業体および加盟国に、次のような新たな義務を導入します:

従業員の定期的な評価 グループ全体のAMLおよびCFT対策 外部委託契約に関する新しい規則 デューデリジェンスおよびKYC手続きの規制 ハイリスク第三国に対する対抗措置 禁止事項および特別義務(例:シェル機関とのコルレス関係) 情報交換の枠組み 文書保持期間 金融情報機関(FIU5)との協力 犯罪収益または資金供与の疑いがある取引の停止 マネーロンダリング又はテロ資金供与のための金融システムの使用を防止するために加盟国が実施すべき仕組みに関する指令(AMLD 6)

AMLD 6は、マネーロンダリングおよびテロ資金供与と戦うための法的解決策の実施における加盟国の義務の範囲を拡大します。具体的には、

加盟国に対し、各人がどこの銀行に口座を持っているかの中央銀行口座登録簿の情報を単一のアクセスポイントを通じて利用可能にするよう規定 各国の法執行機関が、この単一のアクセスポイントを通じてこれらの登録簿にアクセスできるよう保証 犯罪対策と収益の追跡を支援するため、銀行取引明細書のフォーマットを統一(Harmonization of bank statement format) 加盟国に特定の高リスク事業分野へのAML規則の適用拡大を認可 加盟国にゴールデンビザとゴールデンパスポートの問題を規制し、単一の中央口座登録簿を維持することを要求

します。また、AMLAはAMLおよびCFT違反に対する制裁に関する規制技術基準を発行予定です。

予想される市場への影響

EUのアンチマネーロンダリング規制(AMLR)、アンチマネーロンダリング機関(AMLA)、第6次アンチマネーロンダリング指令(AMLD 6)は、より厳格な規制と監視メカニズムを導入することで、市場に大きな影響を与えると予想されています。主な予想される影響は以下の通りです:

ハーモナイゼーションと標準化 単一ルールブック: AMLRは、EU加盟国全体に直接適用される単一の規則セットを確立し、これまでの国内法化を必要とする指令ベースのアプローチに取って代わります。これにより、コンプライアンス基準がより統一され、規制の断片化が減少します。 適用範囲の拡大: AMLRは、暗号資産サービスプロバイダー、高級品取引業者、プロサッカークラブなどのセクターにも適用範囲を拡大し、AML規制の対象となる事業者の数を増やします。 コンプライアンス要件の強化 顧客デューデリジェンス: より厳格な顧客デューデリジェンス(CDD)要件が施行され、実質的所有者の透明性確保やハイリスクな取引・顧客に対する強化されたデューデリジェンスが含まれます。 内部方針と管理: 義務対象事業者は、新しいAML基準に準拠するために、堅固な内部方針、管理、手順を実施する必要があり、これには大幅な運用変更とコンプライアンスコストの増加が伴う可能性があります。 運用面と財務面への影響 コンプライアンスコストの増加: 新しいAML要件を満たすために、追加のリソース、スタッフトレーニング、技術投資が必要となり、企業はより高いコンプライアンスコストに直面します。 技術的適応: 取引監視とコンプライアンス管理のための先進的な技術ソリューションの必要性が、イノベーションを促進し、AMLコンプライアンスツール市場での統合を促す可能性があります。 監督と執行の変更 集中監督: AMLAの設立により、監督と執行が一元化され、国内当局間の調整が強化され、EU全体でAML規則の一貫した適用が確保されます。 直接監督: AMLAは特定の高リスク金融機関を直接監督し、より厳格な監視と潜在的により高額な罰金につながる可能性があります。 市場力学と競争 競争環境: 新規制により、すべての市場参加者が同じ高い基準を遵守することで公平な競争環境が整い、コンプライアンスを遵守する事業者間の競争が激化する可能性があります。 金融サービスへの影響: 金融機関はAML/CFTリスク評価を更新し、プロセスを適応させる必要があり、これが運用効率と顧客関係に影響を与える可能性があります。 長期的な利点 市場の健全性向上: マネーロンダリングとテロ資金供与のリスクを軽減することで、新しいAMLフレームワークはEU金融システムの健全性と安定性を高め、投資家の信頼と経済的安定性を促進する可能性があります。 グローバルな影響力: EUの厳格なAML措置は他の法域の先例となり、AML/CFT基準のグローバルな強化につながる可能性があります。

要約すると、EU AMLR、AMLA、AMLD 6の実施は企業にとって大きなコンプライアンス努力とコストを伴いますが、EU金融システムの健全性を高める、より強固で調和のとれた規制環境をもたらすと予想されます。

こんにちは、富士榮です。

少し間が空きましたが引き続きW3C Verifiable Credentials Overviewを読んでいきます。


Introduction Ecosystem Overview Verifiable Credentials Data Model Securing Credentials Bitstring Status List Additional Publications


今回は4番目のSecuring Credentialsです。

1. Enveloping Proofs

Enveloping proofs of Credentials, defined by this Working Group, are based on JSON Object Signing and Encryption (JOSE), CBOR Object Signing and Encryption (COSE) [RFC9052], or Selective Disclosure for JWTs [SD-JWT]. These are all IETF specifications, or groups of specification like JOSE that refers to JWT [RFC7519], JWS [RFC7515], or JWK [RFC7517]). The Securing Verifiable Credentials using JOSE and COSE [VC-JOSE-COSE] recommendation defines a "bridge" between these and the Verifiable Credentials Data Model v2.0, specifying the suitable header claims, media types, etc.

In the case of JOSE, the Credential is the "payload" (to use the IETF terminology). This is preceded by a suitable header whose details are specified by Securing Verifiable Credentials using JOSE and COSE for the usage of JWT. These are encoded, concatenated, and signed, to be transferred in a compact form by one entity to an other (e.g., sent by the holder to the verifier). All the intricate details on signatures, encryption keys, etc., are defined by the IETF specifications; see Example 6 for a specific case.

このワーキンググループが定義する資格証明書の包括的な証明は、JSON Object Signing and Encryption (JOSE)、CBOR Object Signing and Encryption (COSE) [RFC9052]、または Selective Disclosure for JWTs [SD-JWT]に基づいています。これらはすべて IETF 仕様、または JOSE のような仕様グループ(JWT [RFC7519]、JWS [RFC7515]、または JWK [RFC7517] を参照)です。Securing Verifiable Credentials using JOSE and COSE [VC-JOSE-COSE] 勧告は、これらの仕様と Verifiable Credentials Data Model v2.0 間の「ブリッジ」を定義し、適切なヘッダークレームやメディアタイプなどを指定しています。

JOSE の場合、クレデンシャルは「ペイロード」(IETF の用語を使用)です。これは、JWT の使用方法として JOSE および COSE を使用した検証可能なクレデンシャルの保護で詳細が規定されている適切なヘッダーに先行します。これらはエンコードされ、連結され、署名され、1 つのエンティティから別のエンティティにコンパクトな形式で転送されます(例えば、保有者から検証者に送信されます)。署名や暗号化キーなどに関する複雑な詳細はすべて、IETF 仕様で定義されています。具体的な例については、例 6 を参照してください。 

以前も書きましたがエンベロープ証明はJOSE/COSE/SD-JWTのデジタル署名ですので、特にJOSEについてはOpenID Connectにおけるid_tokenと共通する点も多く、以前からOpenID Connectをやっている人にはとっつき易いと思います。

COSEですか?個人的にバイナリは好きですが万人受け(特に最近は)はしないでしょう。ただFIDO関連やmDLな人は通らないとダメな道だと思います。頑張りましょう。

The usage of COSE [RFC9052] is similar to JOSE, except that all structures are represented in CBOR [RFC8949]. From the Credentials point of view, however, the structure is similar insofar as the Credential (or the Presentation) is again the payload for COSE. The usage of CBOR means that the final representation of the Verifiable Credential (or Presentation) has a significantly reduced footprint which can be, for example, shown in a QR Code.

The [SD-JWT] is a variant of JOSE, which allows for the selective disclosure of individual claims. Claims can be selectively hidden or revealed to the verifier, but nevertheless all claims are cryptographically protected against modification. This approach is obviously more complicated than the JOSE case but, from the Credentials point of view, the structure is again similar. The original Credential is the payload for SD-JWT; and it is the holder's responsibility to use the SD-JWT when presenting the Credential to a verifier using selective disclosure.

COSE [RFC9052] の使用法は JOSE と似ていますが、すべての構造が CBOR [RFC8949] で表現されている点が異なります。しかし、クレデンシャルという観点から見ると、クレデンシャル(またはプレゼンテーション)が COSE のペイロードであるという点では、構造は似ています。CBORの使用により、検証可能なクレデンシャル(またはプレゼンテーション)の最終的な表現は、例えばQRコードで表示できるほど、フットプリントが大幅に削減されます。

[SD-JWT] は JOSE のバリエーションであり、個々のクレームの選択的な開示を可能にします。 検証者に対して、クレームを選択的に非表示または表示することができますが、それにもかかわらず、すべてのクレームは暗号技術によって改ざん防止が保護されています。 このアプローチは JOSE の場合よりも明らかに複雑ですが、クレデンシャルという観点から見ると、構造は再び似ています。SD-JWTのペイロードがオリジナルクレデンシャルであり、選択的開示を使用して検証者にクレデンシャルを提示する際にSD-JWTを使用するのは、所有者の責任です。

はい、CBORを使うメリットはやはりサイズの問題でしょうね。ただ結局はOpenID for Verifiable Credential Issuanceのcredential_offer_uriの様に、間接的にクレデンシャル発行を行う場合ばかりだと思いますので、Wallet to Walletの様なシナリオ以外ではあまり出番はないのかもしれません。

4.1.1 Example: the Core Example Secured with JOSE

The Credential example, shown in Example 1, and enriched with a reference to a JSON Schema in Example 3, can be secured via an enveloping proof as follows:

例 1 の「Credential」の例は、例 3 の JSON スキーマへの参照により強化されており、以下のとおり、エンベロープ証明により保護することができます。

EXAMPLE 6: A Simple Credential in JWT (unencoded) // Header { "iss": "did:example:2g55q912ec3476eba2l9812ecbfe", "alg": "HS256", "cty": "vc+ld+json", "typ": "vc+ld+json+jwt" } --- // Payload { "@context": [ "https://www.w3.org/ns/credentials/v2", "https://www.example.org/vocabs/alumni" ], "id": "https://university.example/Credential123", "type": ["VerifiableCredential", "ExampleAlumniCredential"], "issuer": "did:example:2g55q912ec3476eba2l9812ecbfe", "validFrom": "2010-01-01T00:00:00Z", "credentialSubject": { "id": "https://www.example.org/persons/pat", "name": "Pat", "alumniOf": { "id": "did:example:c276e12ec21ebfeb1f712ebc6f1", "name": "Example University" } }, "credentialSchema": { "id": "https://university.example/Credential123-schema-credential", "type": "JsonSchemaCredential" } 

まぁ、ここはサンプルですが、ヘッダに記載の方式でデジタル署名が打たれる、ということを覚えておけば良いと思います。

As a next step, the header and the payload is encoded, concatenated, and then signed using the methods defined by JWS [RFC7515]. The encoded and signed Credential could look like (using the string "VC Overview" as the signature's secret):

次のステップとして、ヘッダーとペイロードは、JWS [RFC7515] で定義された方法を使用して、エンコード、連結、そして署名されます。 エンコードおよび署名されたクレデンシャルは、次のようになります(署名用の秘密鍵として「VC Overview」という文字列を使用)。

ここもJWSの話ですね。慣れ親しんだ方法です。

The Trimodal Nature of Tech Compensation Revisited

Why does a similar position have 2-4x compensation differences, in the same market? A closer look at the trimodal model I published in 2021. More data, and new observations.

👋 Hi, this is Gergely with a subscriber-only issue of the Pragmatic Engineer Newsletter. In every issue, I cover challenges at Big Tech and startups through the lens of engineering managers and senior engineers. To get articles like this in your inbox, every week, subscribe:

My most frequently-cited article to date is one published before the Pragmatic Engineer newsletter had even launched. It’s The trimodal nature of software engineering salaries in the Netherlands and Europe. I wrote it in 2021, between leaving my role as an engineering manager at Uber and starting this newsletter. 

The article attempted to analyze how tech compensation really works, mainly in the Netherlands. I wrote it because I was confused by the very large differences in compensation figures quoted in tech salary research about pay for senior software engineers, and what Uber actually offered tech professionals in Amsterdam. There was an invisible comp range which nobody talked about and I wanted to find out if this gap was real. And if so: why did it exist?

I based my analysis on 4 years I’d spent as a hiring manager; extending offers, learning about counter-offers, and candidates sharing their comp numbers. It also included around 100 data points from the Netherlands market which I sourced via a form I asked people to share their pay details in.

Three years later, I have comp feedback from hundreds of tech professionals, have spent a load of time talking with hiring managers, CTOs, and founders about pay, and also amassed 10x more data points. So, it’s time for a fresh look at the model!

Today, we cover:

The trimodal model. A summary of the three tiers of the model, and how I detected it while researching the gap between public compensation benchmarks and the ranges I saw as a hiring manager.

Applicability in the US, Canada, UK, Europe, etc. Over the last three years, I’ve received plenty of feedback on the model and it’s proved surprisingly accurate in describing tech compensation structures globally..

Validating the trimodal model with data. I parsed more than 1,000 data points, and manually tagged the company’s tier. Then looked at the distribution with this tagging: which distribution validated the correctness of the trimodal assumption.

Compensation numbers and tier distribution — in the Netherlands. Compensation data points for seniors, staff+, engineering managers and engineering executives. The lowest tier (Tier 1) seems to include the majority of total positions, with the fewest being in the highest tier (Tier 3.) The differences between tiers can help inform what to expect on other markets.

Top-paying (tier 3) companies and mid-paying (Tier 2) ones. Most of Big Tech, hedge funds, and some standout VC-funded scaleups are Tier 3, while VC-funded startups and scaleups, most full-remote companies, and plenty of bootstrapped ones tend to be Tier 2. Pointers to how to locate these kinds of companies.

Top-tier realities. Tiers 2 and 3 don’t really contain many differences in expectations, culture, and workload. Both often operate with a Silicon Valley-like engineering culture and are usually more stressful places to work than tier 1 places.

Beyond compensation. Pay is one of the few quantifiable things that are comparable across all jobs. But much of what makes a job “good” is harder to quantify.

We will go into details – with data – about why this kind of distribution for compensation exists in most markets:

A high-level overview. “$X” varies, but the trends apply internationally. More on the specific numbers behind this graph in ‘3. Validating the trimodal model with data.’

This article harnesses data from several previous issues of this newsletter. You won’t be surprised that I recommend them as useful extra context:

Senior-and-above compensation: an overview of senior+ compensation at the 50th, 75th and 90th percentile across global tech markets. A benchmark for getting a sense of pay differences in your region, versus the US, UK or EU.

Compensation at publicly traded tech companies: a good place to identify which public companies may be top tier (3.)

A closer look at top-tier (3) compensation structures: details of Meta and Pinterest.

A closer look at mid-tier (2) compensation structures: details of Wise and (now-defunct) Pollen.

1. The trimodal model

In this article, we discuss total compensation, not just base salary. Total compensation consists of:

Salary: Monthly / bi-weekly compensation, dependent upon country. Most companies in the US, Canada, Australia and Latin America issue paychecks twice a month, while in most of Europe and Asia it’s once a month.

Cash bonus: Usually paid annually, although some companies do it twice a year. Bonus amounts aren’t guaranteed and often depend on a company’s or employee’s performance, or both. A cash bonus is also known as a “profit share” and is rarely revealed before issuance.

Equity. At publicly traded companies, equity is restricted stock units (RSUs) which can be sold after vesting. For privately-owned startups and scaleups, it’s usually double-trigger RSUs, options, phantom shares, SARs (stock appreciation rights,) or more exotic things like growth shares. For more detail, check out Equity 101 for software engineers. Note, almost always it’s only VC-funded startups and publicly traded companies which offer equity.

Back in 2021, I collected around 100 data points on the Dutch market of small local companies, all the way to international businesses like Booking.com, Databricks, Uber, and more. I mapped out the numbers and plotted a line on the graph:

The 2021 graph based on circa 100 data points in the Netherlands. The graph looked similar for senior and mid-level positions (explained plotting of the graph in the next section, ‘Numbers and tier distribution’)

This graph was not what I expected, which was something closer to normal distribution. ‘Normal distribution’ (aka Gaussian distribution) is a common concept in statistics, mapping the probability distribution of a random variable. If we know median total compensation is $X, a normal distribution graph looks something like this:

Normal distribution of compensation around a median value of $X

Normal distribution doesn’t inevitably occur, but experience shows that it frequently describes things containing some degree of randomness, such as human height, blood pressure, exam scores, IQ scores, reaction times – even shoe sizes.

Could this compensation graph be a collection of three other distinct graphs? I noticed three “local maximum” spots:

It’s unusual for a single distribution to have three “local maximums,” as above

But what if the graph was not one distribution, but three distinct ones? That would explain the strange shape, and the three local maximums. I  grouped the data points behind the graphs, and sure enough, found three different groups:

Local companies (Tier 1): most local businesses that benchmark to the numbers on most salary comparison sites. They usually offer close to – and sometimes slightly above – what government positions advertise for senior engineering roles.

Ambitious local companies (Tier 2): startups, scaleups, and more ambitious local companies that want to hire and retain the best people, locally.

Companies benchmarking across a region (Tier 3). Big Tech companies, hedge funds and scaleups that hire across regions, frequently hire from abroad, and often compete with fellow Big Tech giants for talent.

Mapping these three groups separately to the same data I plotted before, produced this:

Grouping compensation numbers based on three company types

This graph looked pretty sensible, and the three distributions more normal. These were still not “normal” distributions, but the “long tails”of tiers 2 and 3 compensation components were explained by equity appreciation. Specifically, outlier data points (very high total compensation numbers) were almost all people who received an equity grant which had appreciated 5-10x since issuance, pushing up total compensation.

The trimodal model explained why public salary benchmarks seemed wrong. It was puzzling that sites like Payscale, Honeypot, and similar sites published median compensation numbers that seemed too low, and did not even hint at the higher packages that clearly exist at the market. The trimodal model explained what was happening: all these sites were only showcasing data for the lowest tier, Tier 1 — and perhaps a few data points for Tier 2. Looking at my model, this checked out:

The “invisible range” in most public tech compensation reports seemed to fully omit the highest-tier (Tier 3) compensation packages

Comparing data within the Netherlands, it all checked out. Sites like Honeypot and Talent.io reported the median senior software engineering salary was around €60,000/year ($65,000) and they were right: for Tier 1 packages only! I also observed it was possible to find a few more data points in the Tier 2 range scattered among individual data points on sites like Glassdoor, but that there was little public data on Tier 3 – the “invisible” range.

There seem several reasons why there’s so little data on Tier 3.

Relatively few compensation packages, which means sites that look at median, average, or even the 75th percentile, exclude them.

Top earners have little incentive to share their numbers; they know they’re well above publicly reported median numbers.

Many compensation sites do not capture equity in compensation packages. This is because the majority of compensation packages do not have equity (Tier 3 packages are a minority in all markets!), so most sites have not added support to capture this component. And yet, equity is usually the biggest reason for the difference in compensation. But to know this, a site needs to capture equity details!

But in the past few years more data has been published about the top of the market. Salary sharing and offer negotiation site Levels.fyi is the best-known source, covering virtually all top-tier (Tier 3) companies in the US. Other sources include Blind, an anonymous social network used by many working in tech, where people are expected to share their total compensation – aka TC – in each post, and some Reddit forums.

Confident that I had sufficient data points for the Netherlands, I published this graph and accompanying article.

2. Applicability in the US, Canada, UK, Europe, and beyond

At the time I didn’t know if the model applied beyond the Netherlands because all data I’d sourced related to that country. The lowlands nation has characteristics that overlap with the US, European countries, and other places with venture-funded tech companies:

US Big Tech is growing. Amazon is expanding its AWS organization in the Netherlands, as is Google Cloud with GCP. Meta also started hiring locally from 2021, and Uber has its European headquarters there.

VC-funded companies with headquarters elsewhere. Plenty of tech companies hiring in the Netherlands are headquartered in the US, UK, and other European countries, and hire heavily in the Netherlands. Examples include Databricks, Stripe, Personio, Fonoa, Linear.

Hedge funds. Few cities in the world have hedge funds and high frequency trading funds hiring software engineers in large numbers. London and New York are the best-known locations, along with Amsterdam. Companies like Optiver, Flow Traders and IMC Trading hire there. 

Local VC-funded companies. Mollie (a Stripe competitor valued at $6.5B,) Messagebird (a Twilio competitor valued at $1B,) and Adyen (another Stripe competitor, publicly traded, with a market cap of $35B) are companies founded in the Netherlands that raised venture capital.

The bulk of software engineers are still hired by “local” companies. My sense is that most developer hiring happens this way.

Other countries share these characteristics to varying degrees.

The model seems to hold up well, internationally. Since publication, feedback has been continuous, and hiring managers and engineers confirm the model explains the dynamics in their countries and regions – with only the numbers needing adjustment.

I’ve talked with founders and hiring managers in the US, Canada, UK and EU, who shared that this model is relevant to them.

US: 

“I think the Trimodal nature of salaries will apply to the U.S., as well. No data, it's anecdotal, but it's what I have seen in my own experience and in conversations with IC's and managers across all three types of companies.” – VP of engineering Rick Luevanos

“Ignore the absolute numbers if you aren’t in Europe. The trends are the same in the US. I left the first category and moved into the second category last year.” – a software engineer in a post on Reddit

“Moved to Ireland from northern California and have been interested (and delighted) to see SV companies pushing up salaries here. Trimodal salary matches my experiences closely.” – a software engineer in the US

In an interesting follow-up, compensation negotiation and salary benchmarking site Levels.fyi found the model perfectly explains US internship salary ranges:

The model fits US software engineering intern salaries, as analyzed by Levels.fyi

Canada: 

“This is exactly what I experienced in Canada. Tier 1 category companies are the most prevalent and the pay is subpar. I've 2.5x [increased] my salary over the past couple years by getting into Tier 3.” – a software engineer in a post on Reddit

“In general, most Canadian companies are just competing with other Canadian companies and they get away with paying very little. This often changes when they get big and have to start hiring in the US as well (Slack, Shopify, etc.) But this doesn't really change the local market very much.

This is changing slowly with remote work. Big US companies are starting to hire more in Canada because they're getting the same performance for like 75% of the salary. But things are still in flux. Most Canadian companies are still competing with each other and not with the US firms, so you have to jump jobs in order to get that pay raise.

In your terms you're changing "brackets", but really, you're changing "tiers". You're moving from a low paying tier to a higher one.” – a senior principal engineer on Glassdoor

UK: based on data I collected on TechPays, for the UK, the trimodal split describes the UK market well. Compensation packages are higher than in the Netherlands in all tiers by about 15-30%.

New Zealand: 

“Slightly different reasons, but I'm seeing something similar in New Zealand. Domestic companies benchmark against each other, and pay lower salaries. Meanwhile Australian companies have mostly come to terms with remote work after the lockdowns, which makes NZ a valuable recruitment market. 

And since they benchmark against each other and because NZ is so small, close, and similar, Australian firms mostly don't adjust their salary bands from (higher) Australian norms, so they pay 25-30% more for comparable roles than a domestic NZ company would. Meanwhile, a few American companies are also starting to recruit, and again, most don't adjust their salary bands, and so generally pay 50-80% more than domestic NZ companies.” – a software engineer in a comment on Hacker News.

Japan: software engineer Patrick McKenzie (resident in Japan) suspects the same applies there:

Source: Patrick McKenzie on X

I created this model to explain compensation for engineers and engineering managers, but it seems to hold for product managers, and roles across tech. — who writes the publication — was a VP of Product and worked at Apollo.io, Affirm, and Epic Games. He concluded:

“If you can get a job at the right company, you can earn 3-5x local companies.

I find the [trimodal] distribution applies to most jobs: engineering, PM, tech, non-tech.”

3. Validating the trimodal model with data

After publishing the model, I launched a side project called TechPays, a site where people can anonymously submit compensation numbers. It’s geared mainly towards Europe, where there are fewer data points for higher tiers. I analyzed detailed data points submitted in 2022. In that year, there were 1,100 submissions for the Netherlands, and 482 were for senior software engineer positions; nearly 10x more data than in the original model.

So, how does the model hold up with the additional data? Cutting out distant outlier data points at the bottom and top, it did pretty well. Here is the 482 data points for senior software engineers with no grouping:

Number of reported data points in a total compensation bracket. Source: TechPays.com

Let’s plot these data points into a line:

Distribution of senior software engineer total compensation data points

I manually tagged each company with the tier that was most appropriate:

Distribution of senior software engineer total compensation data points, after tagging each company behind the data point with their appropriate tier

Here’s what happens when applying the trimodal model after tagging each company by tier:

Dividing companies into three tiers and visualizing the same data

Let’s clean the chart up by removing distracting lines and numbers:

Dividing companies into three tiers, and visualizing the same data

As we’ve built up this model from the ground up, using data, we got to a very similar graph to what I hand-drew in 2021. The model seems to hold up: now backed with data.

StopKillingTrains? EU-Abgeordneter fordert Regeln gegen das willkürliche Lahmlegen von Geräten durch Hersteller aus der Ferne

Auf Anfrage des Europaabgeordneten der Piratenpartei Dr. Patrick Breyer hat sich EU-Binnenmarktkommissar Breton zu Herstellern, die ihre Produkte mit Abschalteinrichtungen oder „kill switches“ ausstatten, geäußert. Anlass für diese Anfrage war ein aktueller Fall, bei dem festgestellt wurde, dass der polnische Zughersteller NewAg in mehrere elektrische Triebzüge „Abschalteinrichtungen“ eingebaut hat, die unter bestimmten Bedingungen (Standort oder Betriebsdauer) die Stromzufuhr und die Kompressoren des Zuges abschalten. Durch die Abschaltfunktion wollte der Hersteller u.a. eine Reparatur der Züge durch Konkurrenzunternehmen und auch eine Analyse der Zugsoftware verhindern. In seiner Antwort räumt EU-Kommissar Breton ein, dass bestehende oder geplante EU-Regeln zum Recht auf Reparatur weitgehend auf den Schutz von Verbrauchern beschränkt sind und auf Betriebsvermögen keine Anwendung finden.

Patrick Breyer kommentiert:

„Diese Praxis einiger Hersteller, die Reparatur und Wartung ihrer Produkte durch unabhängige Unternehmen zu erschweren oder gar zu verhindern, ist inakzeptabel. Die EU sollte klare Regelungen schaffen, um derartige Übergriffe zu unterbinden und die Rechte der Läufer sowie die Wettbewerbsfähigkeit unabhängiger Reparaturdienste zu schützen. Das Recht auf Reparatur muss genauso für Unternehmenskunden gelten.

Ein bloßes Recht auf Reparatur greift im Informationszeitalter aber zu kurz. Nutzer müssen die volle Kontrolle über die Technologie haben, die sie in ihrem täglichen Leben verwenden. Wir müssen das Recht haben, unsere rechtmäßig erworbenen Geräte selbst zu verändern, anzupassen und zu verbessern. Dass das Urheberrecht dies bisher ausschließt, ist entmündigend und lädt zu Missbrauch ein, wie der polnische Fall zeigt.“

Eine ähnliche Problematik wird auch bei Computerspielen beobachtet, bei denen Hersteller beliebte Spiele nach Belieben unbrauchbar machen. In Zusammenarbeit mit der Spielerinitiative „Stop killing games“ fordert Patrick Breyer einen Kulturschutz für Games.

This article looks at different ways to create hashes in .NET Core. Hashes are useful for one way encryption which can be used for password storage, JWT validation and some other security use cases. When storing hashes in a database, extra care must be taken and the recommended approach from Microsoft should be used when implementing this. In general, creating hashes and storing the hashes in a database should be avoided as much as possible

History 2024-07-01 Updated the SHA512 hash methods using feedback from Kévin Chalet Using SHA512

The fastest and simplest way is to user the SHA512 directly. This takes a string and hashes it directly using a one way encryption. This is good when the hashes are not persisted in a database or when attackers don’t have time to do a dictionary attack.

public static string ToHashedCodeV1(string code) { using var sha512 = SHA512.Create(); var bytes = Encoding.UTF8.GetBytes(code); var hash = sha512.ComputeHash(bytes); return Convert.ToBase64String(hash); } public static bool VerifyCodeV1(string code, string storedCode) { using var sha512 = SHA512.Create(); var bytes = Encoding.UTF8.GetBytes(code); var hash = sha512.ComputeHash(bytes); var storedHash = Convert.FromBase64String(storedCode); return CryptographicOperations.FixedTimeEquals(hash, storedHash); }

The SHA512.HashDataAsync method can also be used to create the hashes.

public static async Task<string> ToHashedCodeV2(string code) { var bytes = Encoding.ASCII.GetBytes(code); var hash = await SHA512.HashDataAsync(new MemoryStream(bytes)); return Convert.ToHexString(hash); } public static async Task<bool> VerifyCodeV2(string code, string storedCode) { var storedHash = Convert.FromHexString(storedCode); var bytes = Encoding.ASCII.GetBytes(code); var hash = await SHA512.HashDataAsync(new MemoryStream(bytes)); return CryptographicOperations.FixedTimeEquals(hash, storedHash); }

Using Rfc2898DeriveBytes.Pbkdf2

The Rfc2898DeriveBytes.Pbkdf2 method can be used to create hashes and when using this, a salt of 8 bytes or more should be used and more than 10000 iterations. This makes it harder to reverse engineer the original hash values.

private const int _keySize = 32; private const int _iterations = 10000; private static readonly HashAlgorithmName _algorithm = HashAlgorithmName.SHA512; public static string ToHashedCode(string toHash, string userId) { var salt = Encoding.UTF8.GetBytes(userId); var hash = Rfc2898DeriveBytes.Pbkdf2( toHash, salt, _iterations, _algorithm, _keySize ); return Convert.ToBase64String(hash); } public static bool VerifyCode(string code, string userId, string storedCode) { var salt = Encoding.UTF8.GetBytes(userId); var storedHash = Convert.FromBase64String(storedCode); var hash = Rfc2898DeriveBytes.Pbkdf2( code, salt, _iterations, _algorithm, _keySize ); return CryptographicOperations.FixedTimeEquals(hash, storedHash); }

Using ASP.NET Core Identity

ASP.NET Core Identity provides interfaces to create password hashes for data storage. You can use any C# type to define the password hasher and the Identity user class is normally used to create an instance of the PasswordHasher class. The hashes from this implementation can be saved to a database. This hash implementation is slow to create the hashes.

private readonly PasswordHasher<string> _passwordHasher = new(); public static string ToHashedCode(string code, string userId, PasswordHasher<string> passwordHasher) { var hash = passwordHasher.HashPassword(userId, code); return hash; } public static bool VerifyCode(string code, string userId, string storedCode) { var passwordHasher = new PasswordHasher<string>(); var result = passwordHasher.VerifyHashedPassword(userId, storedCode, code); return result == PasswordVerificationResult.Success; }

Notes

Using the right hash implementation is important and choosing the wrong one could result in a security problem. You should aim for solutions where implementing this should not be required. When storing hash values to a database, the Microsoft recommendations should be followed. Best would be to use the default implementation from ASP.NET Core Identity, when this is possible.

Eleventh in the News Commons series.

all experience is an arch wherethro’
Gleams that untravell’d world whose margin fades
For ever and forever when I move.
Alfred, Lord Tennyson, in Ulysses

News flows. It starts with what’s coming up, goes through what’s happening, and ends up as what’s kept—if it’s lucky.

Facts take the same route. But, since lots of facts don’t fit stories about what’s happening, they aren’t always kept, even if they will prove useful in the future. (For more on that, see Stories vs. Facts.)

But we need to keep both stories and facts, and not just for journalists. Researchers and decision-makers of all kinds need all they can get of both.

That’s why a news commons needs to take care of everything from what’s coming up through what’s happened, plus all the relevant facts, whether or not they’ve shown up in published stories. We won’t get deep, wide, or whole news if we don’t facilitate the whole flow of news and facts from the future to the past.

Let’s call this the Tennyson model, after Lord Alfred’s Ulysses, excerpted above. In this model, the future is a calendar such as the one in DatePress. The present is is news reporting. The past is archives.

Calendars are easy to make. They are also easy to feed into other calendars. For example, take the Basic Government Calendar, of Bloomington, Indiana. That one is built from 50+ other calendars (to which it subscribes—and so can you). The Big Big Calendar (be patient: it takes a while to load) covers many other journalistic beats besides government (the beat of the B Square Bulletin, which publishes both).

We describe approaches to archives in The Online Local Chronicle and Archives as Commons. Here in Bloomington, we have two examples already with BloomDocs.org and The Bloomington Chronicle. Both are by Dave Askins of the B Square Bulletin using open-source code. And both are new.

Relatively speaking, Bloomington is a news oasis (see our list of media life forms in Wide News) in a world where news deserts are spreading. So we’ve got a lot to work with. If you want to help with any of it, let me know.

—is not this:

A netizen isn’t just an account-holder

By now we take it for granted.

To live your digital life on the Internet, you need accounts. Lots of them.

You need one for every website that provides a service, plus your Mac or Windows computers, your Apple or Google-based phones, your home and mobile ISPs. Sure, you can use a Linux-based PC or phone, but nearly all the services you access will still require an account.

Everything that requires an account has a lock on you—for their convenience. They don’t know any other way. That’s because all the services we use in the online world operate inside a model called client-server, which looks like this:

This is great for the server operator, but not for the rest of us:

This was not the promise of the Internet described by John Perry Barlow in Death From Above in 1995 and A Declaration of the Independence of Cyberspace in 1996. Nor was it what Chris Locke, Rick Levine, David Weinberger, and I said in The Cluetain Manifesto‘s ‘one clue’—

—and in the 95 Theses that followed, starting with these:

Since I’ve often heard that an unintended consequence of Cluetrain was causing social media in some way, I just asked ChatGPT and Perplexity the same question: Did The Cluetrain Manifesto help start social media? The answers were roughly the same, but Perplexity provides sources, so I’ll quote that answer:

The Cluetrain Manifesto did not directly start social media, but it did play a significant role in predicting and shaping the philosophy behind social media marketing and online communication. Published in 1999, the manifesto anticipated many of the changes that would occur with the rise of social media and online conversations. (link) (link)

Key points about The Cluetrain Manifesto’s influence on social media:

Predicted global conversations: The manifesto accurately foresaw that the internet would enable powerful global conversations, allowing people to share knowledge rapidly (link). Emphasized authentic communication: It stressed the importance of companies engaging in genuine, human conversations with customers, which became a cornerstone of social media marketing (link) (link). Highlighted networked markets: The manifesto recognized that customers were becoming more connected and influential through online networks, a concept that social media platforms later embodied (link). Challenged traditional marketing: It criticized the “homogenized voice” of traditional business communication, encouraging a more authentic and conversational approach that social media later facilitated (link). Empowered employees: The manifesto suggested that companies should empower employees to engage with customers, an idea that became crucial in social media strategies (link). Recognized the shift in power: It predicted that customers would gain more influence over companies through online conversations, which social media platforms later enabled (link).

While The Cluetrain Manifesto didn’t create social media technologies, it provided a philosophical foundation that aligned closely with how social media would eventually function. Its ideas about authentic communication, networked conversations, and customer empowerment became central to social media marketing strategies and practices (link) (link) (link).

Alas, we all still are seats, eyeballs, end users, and consumers, and our reach still does not exceed corporate, government, and organizational grasp, because all of those entities operate their services on the client-server model. And, so long as nearly everyone believes that client-server is the only way to go, the fact that the Internet is end-to-end beneath everything done on it remains irrelevant. Nothing in any of these (and many other) efforts before and since has done anything to change the damned Internet of Accounts:

The Rise of the Stupid Network (by David Isenberg) in 1997 The Cluetrain Manifesto in book form, in 2000 and in a 10th Aniversary version (with seven new chapters) in 2010 World of Ends (by David Weinberger and me) in 2003 Internet Identity Workshop (by Phil Windley, Kaliya Young, and me) since 2005 ProjectVRM (by hundreds of people and projects) since 2006 The Intention Economy, a book by me in 2012 New Clues (by David Weinberger and me) in 2015

I do, however, see hope coming from three angles.

First is self-sovereign identity, or SSI. I’ve written about SSI in many ways and places over the years, but perhaps the best is New Hope for Digital Identity, published in Linux Journal back in 2017. What SSI wishes to replace is the familiar client-server model in which you are the account holder, and two servers are the “identity provider” and the “relying party.” With this system, your “ID” is what you get from the identity provider and their server. With SSI, you have a collection of verifiable credentials issued by the DMV, your church, your school, a performance venue, whatever. They get verified by an independent party in a trustworthy way. You’re not just a client or just an account holder. You disclose no more than what’s required, on an as-needed basis.

Second is contract. Specifically, terms we proffer as first parties and the sites and services of the world agree to as second parties. Guiding the deployment of those is IEEE P7012 Standard for Machine Readable Personal Privacy Terms, which I’ve called the most important standard in development today. I’m the chair of the P7012 working group, which has been on the case since 2017. The standard is now drafted and moving though the IEEE’s approval mill. If all goes well, it will be ready early next year. It works like this:

Possible agreements sit at a public website. Customer Commons was created for this purpose, and to do for personal contracts what Creative Commons does for personal copyrights. The person’s agent, such as a browser, acting as the first party, tells the second party (an entity of any kind) what agreement the person has chosen from a small roster of them (again, on the Creative Commons model). The entity either agrees or declines. If the two agree, the decision is recorded identically by both parties. If the entity declines, that decision is also recorded on the person’s side.

Customer Commons has one such agreement already, called P2B1 (beta), or #NoStalking. As with all contracts, there’s something in it for both parties. With #NoStalking, the person isn’t tracked away from the site or service, and the site or service still gets to advertise to the person. Customer Commons (for which I am a founder and board member) plans to have a full list of agreements ready before the end of this year. If this system works, it will replace the Internet of Accounts with something that works far better for everyone. It will also put the brakes on uninvited surveillance, big time.

Third is personal AI. This is easy to imagine if you have your own AI working on your side. It can know what kind of agreement you prefer to proffer to different kinds of sites and services. It can also help remember all the agreements that have been made already, and save you time and energy in other ways. AI on the entities’ sides can also be involved. Imagine two robot lawyers shaking hands and you can see where this might go.

There are a variety of personal (not just personalized) AI efforts out there. The one I favor, because it’s open source and inspired by The Intention Economy, is Kwaai.ai, a nonprofit community of volunteers where I also serve as chief intention officer.

I welcome your thoughts. Also your work toward replacing the Internet of Accounts with the Internet of People—plus every other entity that welcomes full personal agency.

For a long time there were only two essential things that I carried everywhere: keys and wallet. Two was a manageable number of objects that I had to remember to put into pockets, and two was a manageable number of pockets to put them in.

Then my first phone bumped that number to three. When reading glasses became the fourth must-carry item, it started to feel like there were too many objects to always remember and too few pockets to put them in. When the seasons changed, or when traveling, it got harder to reset the canonical locations for all four things.

Although I listen to tons of podcasts, headphones never made the list of always-carry items. But when I emptied my pockets the other day I realized that my magic number is now five. AirPods are the new take-everywhere item.

For a while I resisted the recommendation to upgrade from a wired headset to AirPods. Did I really need another small, rechargeable, easy-to-lose object (actually, three of them)? I’ve learned not to expect that yet another electronic gadget will improve my life. But this one has. Dave Winer, you were right.

Obviously this trend can’t continue indefinitely. Will that thing we anachronistically call a “phone” absorb the wallet, and maybe even the keys? I’m not sure how I feel about that!

Meanwhile, there’s my trusty belt pack. It’s dorky but there’s a pocket for everything, and it works consistently across seasons and continents.

Auto-Tuned Biofields and Curious Ontopoesis

This week Stephers came across a document that was put out by the Consciousness and Healing Initiative in 2020 with financial support from Jason Youtopolous (former head of SAP Global Research) with the Emerald Gate Foundation, the Walker Family Foundation (Jeffrey C. Walker formerly of JP Morgan, MIT Media Lab, Berklee School of Music and [...]

This week Stephers came across a document that was put out by the Consciousness and Healing Initiative in 2020 with financial support from Jason Youtopolous (former head of SAP Global Research) with the Emerald Gate Foundation, the Walker Family Foundation (Jeffrey C. Walker formerly of JP Morgan, MIT Media Lab, Berklee School of Music and Board Chair of New Profit) and Tom Dingledine (oil exploration, UVA, and Wake Forest University donor).

Subtle Energy and Biofield Healing: Evidence, Practice, and Future Directions” is a systems change plan to implement standards, evidence collection, and technology development that will restructure loosely networked healers and body workers into a global investment market. I believe those markets will, in turn, manage human psyches and etheric fields in the name of “health,” “wellbeing,” and “self-care” through telemedicine. The ultimate goal is to replace healers with apps linked to blockchain health records / digital twins, optimizing agents in the simulation and facilitating noetic convergence.

Bobby and Nicole’s promotion of AI-mediated healthcare and Web3 to address our nation’s chronic health “emergency” would dovetail nicely with such an effort. Remember, RFK Jr. gave a keynote speech at the 2008 Omega Institute conference in Rhinebeck, NY on the importance of water to carbon-neutral sustainable living.

I anticipate new markets in digital alternative medicine will be hooked up to pay for success finance deals and programs like John Pollak’s CommonHealth Wellcoin effort based out of Cornell-Technion. With JP Morgan and Silicon Valley venture capital involved, how could it not? Oh, and a major funder is the Rob and Melani Walton Foundation. Rob is worth $61 billion as the former chair of Walmart. His sister, Alice, is working closely with Deepak Chopra on community wellness and mindfulness as well as public art.

As with the field of education, my point of entry into the matrix, it seems human involvement will be gradually minimized in favor of automated systems. Touch will be studied and mirrored into AI assistants where sensors and actuators (sound, light, and haptics) end up embedded into spatial computing where they can facilitate our creative human potential as parallel processors in the networked collective, the digital commons as shared computational game board.

Human agents in the “game” remade as gooey, foraging nodes of slime mold in the name of democracy, free markets, and the American way if you are conservative. If you’re an NPR progressive / leftist, then your story will be that we need Web3 digital alternative health to uplift indigenous culture, stop capitalism, and save the planet from the Anthropocene. These folks have enough money to buy all the stories, and they know what each of us wants to hear. They’ll know even more once they use the alternative health space, keepers of etheric bodies, to bring us under their engineered dome. 

The two-hour talk below starts with a thought experiment I’ve been having about Web3 possibly being a “language” to interface with energetic elemental beings in a different layer of information space. I need to do more looking into Gurdjieff’s “law of three” and carbon (wallets) signifying action. The language may actually be envisioned as a vehicle for group manifestation into our shared information realm. Yes, I know that sounds highly unusual, but the more research I do the more I realize that high-level physics is not so far off spiritualism. Given all the money that the US military has spent in these areas over the past century makes psychical research hard to discount.

In the talk below, I touch on the movie “Arrival” and Thomas Mayer’s book “Answering the Call of the Elements.” Mayer is an Austrian teacher of Anthroposophic meditation who engages with elementals and has spent several decades working in direct democracy and positive Swiss money systems. Sure sounds to me like token engineering and gamified protocol layers may be a planned communication infrastructure. I then describe several serendipitous experiences I have had in Arkansas over the past month – not really synchronicities, more in the line of ontopoetics, a term I just learned but am enjoying playing with in the context of Wheeler’s participatory universe and Basil Hiley’s non-commutative active information fields. Recent pics are included in the presentation and below. Who knows, there may be some clues I need to refer to later.

Enjoy!

 

If you feel like it, once you’re done with the talk and have browsed the document, consider Michael Levin’s discussion of manipulating bioelectrical fields. My sense is the biofield / AI electroceutical program mediated by AI / Blockchain smart contracts is meant to facilitate the emergence of a global soul-based computational superorganism.

Just a Theory

Patch: Postgres ABI and API Guidance

Dear Postgres extension developers: Please review and give feedback on the proposed patch adding ABI and API Guidance to the C language documentation.

TL;DR: If you’re a Postgres extension developer interested in understanding what to expect from core API and ABI stability, please review and give feedback on this patch (or pull request) adding ABI and API Guidance to the documentation.

In my PGConf.dev report a couple days ago, I mentioned that a few actionable items came out of the Improving extensions in core unconference session. One was the need to document the heretofore unofficial policy for API and ABI stability between major and, especially, minor versions of Postgres.

A frequent topic at the Extension Summit and Mini-Summits and a number of PCConf sessions has been concern regarding compatibility changes between minor releases of Postgres. At Mini Summit Five, for example, Yurri Rashkovskii presented a few examples of such changes, leading him to conclude, along with several others in the community, that C API-using extensions can only be used when built against the minor release with which they’re used.

In the Unconference session, core committers reported that such changes are carefully made, and rarely, if ever, affect extensions compiled for different minor releases of the same major version. Furthermore, they carefully make such changes to avoid compatibility issues. In the case Yurii found, for example, a field was added to a struct’s padding, without affecting the ordering of other fields, thus minimizing the risk of runtime failures.

It became clear that, although the committers follow a policy — and read new committers into it via patch review — it’s not documented anywhere. The result has been a bunch of sturm und drang amongst extension developer unsure what level of compatibility to depend on and what changes to expect.

The week after the conference, I started a pgsql-hackers thread proposing to document the committer policy. Following some discussion and review of potential ABI breaks in minor releases, the consensus seemed to be that the committers strive to avoid such breaks, that they’re quite uncommon in minor releases, and that most of the reported issues were due to using more obscure APIs.

As a result, we started drafting a policy, and after a few iterations, Peter Eisentraut pulled things together from the perspective of a core team member, reframed as “Server API and ABI Guidance”. I converted it into a patch (and pull request) to add it to the C Language docs. A key statement on minor releases:

In general, extension code that compiles and works with a minor release should also compile and work with any other minor release of the same major version, past or future.

I hope this document clarifies things. Even if it’s not as strict as some might hope, it at least documents the project approach to compatibility, so we have a better idea what to expect when using the C APIs. If you see gaps, or you have additional questions, please respond to pgsql-hackers thread — or the pull request (I’ll propagate comments to hackers).

The Pulse #98: Is there a GenAI startup cooldown or not?

Plenty of signs point to a cooldown happening, but there’s also GenAI mega-funding rounds. Also: Polyfill.js supply-chain attack, the importance of internships, and more.

The Pulse is a series covering insights, patterns, and trends within Big Tech and startups. Notice an interesting event or trend? Send me a message.

Today, we cover:

Industry pulse. Volskwagen partnering with Rivian to get better software, SaaS scaleups struggling to raise, EU unhappy with Apple’s DMA non-compliance, why so few tech IPOs, and more.

GenAI startup cooldown? Plenty of signs point to a cooldown across GenAI startups: many are struggling to generate meaningful revenue, there’s a drop in seed-stage AI VC funding, and also some AI startup fire sales. At the same time, we see massive funding rounds at the likes of Perplexity, Mistral, and Cognition Labs. Can the market be hot for large companies and chilly for smaller startups at the same time?

Popular Javascript library infested with malware. More than 100,000 websites started serving malware after the unpaid maintainer of polyfill.js sold their project, and the new Chinese owner started to inject malware into sites. This is yet another reminder to audit dependencies, and prepare for more attacks in the future.

Proof that well-run internships matter. One of the first interns I hired at Uber seven years ago, is still at the company. It all started with a well-organized internship, where our goal was to achieve returning interns who wanted to come back next year.

1. Industry pulse Volkswagen to Rivian’s rescue?

Rivian is a popular EV maker in the US, producing the Rivian R1T; the first electric pickup truck. The vehicle is known for its impressive range of around 400 miles / 650km, off-road capability, and innovative features.

But the automaker is in financial trouble, following a successful 2021 IPO. As we covered in April, the company is at risk of running out of money in a few years time:

The company’s current market cap reflects the risk of a potential bankruptcy down the road: in 2021 RIvian was valued at $150B: but a week ago, it was down to $10B.

This week, things changed for the better. Volkswagen announced a joint venture with Rivian, in which the German automaker provides $5B of capital, and in return, Rivian’s software powers Volkswagen cars.

This partnership seems like an ideal solution to both company’s problems. Rivian has great vehicles and software, but needs money. Volkswagen has plenty of cash, but its software is known to be terrible and buggy, to the point that it costs the company customers. I previously test drove a Volkswagen EV, the ID3 model, and its unresponsive software – alongwith reviews stating the same – was enough to not spend more time evaluating it.

This must be what a “win-win” looks like! Congrats to Rivian; and hopefully Volkswagen’s customers also benefit from this venture.

It was a derecho, or something like one. The gust front you see in the third image here

Derecho. (2024, June 24). In Wikipedia. https://en.wikipedia.org/wiki/Derecho

—looks a lot like the storm front in the top image above (via Weatherbug, storm tracker view). I’d experienced one twelve years ago, in Arlington, Mass. It felt like a two minute hurricane, and when it was over, hundreds of trees were down. This one wasn’t as bad, but TwitteX seemed to agree that it was a derecho. And we did have many broken trees and power outages. Here’s one example of the former:

That’s half a huge silver maple. Very luckily, it missed the house and only trashed the metal fence. Pretty house, too.

There was also a lot of lightning as well. Dig:

You can barely see the blue dot in the middle, but that’s where we live. One of those red dots is about a hundred feet from where I’m writing this.

If you’re into this kind of stuff, I recommend the My Lightning Finder app, which produced the above. Also LightningMaps.org on the Web. That one shows thunder as gray circles expanding and fading at the speed of sound moving outward from a lightning dot. Of course, lots of those lightning dots are lines in clouds, or zig-zags between ground and sky. They aren’t all “strikes.”

But when lightning does strike, one of my favorite storm sounds is a loud crack, then “Cccchhhheeeeeooooowwwwwww” before a BOOM of thunder slams the ground. What you’re hearing after the crack is sound coming off the length of the lightning strike, starting at the ground and moving up to the cloud above. The volume of the sound and its pitch go down as they originate from farther and farther away along the length of the lightning bolt itself. The BOOM is produced by the top of the bolt, which typically fans out inside the cloud, parallel to the ground, in a shape that looks something like the letter T, with the top crossbar parallel to the ground. The BOOM comes at you from the top of the bolt. Listen for the whole show the next time you’re in a storm and lightning strikes nearby.

[Later, 1:00 am on 27 June…] Much of the city is still without power. Also, this photo on Reddit, shot from the west side Aldi, shows the kind of rain that produces a derecho.

Also, from the Monroe County Emergency Management Storm Update 1 p.m. on 6/27/24:

More than 100 damage reports have been collected by Indiana 211 following Tuesday’s storm event in Monroe County. The National Weather Service confirmed straight-line winds of 65-75 mph damaged homes and property in Monroe, Owen, Vigo and Clay counties. All four counties have declared, or plan to declare, local disasters due to the incident. No reports of significant injuries have been received at this point. Impacted residents in these four counties are asked to call 211 to report damage or visit the website at https://in211.org.
Damage
Most of these reports involve overturned trees into homes, some with significant damage. Only a handful of residents reported their homes to be uninhabitable. The local Salvation Army reported only two residents utilized the shelter established at their location, 111 N. Rogers St… As of 1 p.m. Thursday, approximately 28,000 power outages were reported across Indiana, with nearly 16,000 of those reported in Monroe County.

Thanks to Dave Askins of the B Square Bulletin for that one.

Just a Theory

PGConf.dev 2024

At PGConf.dev, I attended some great talks, made one of my own, and enjoyed the commearderie of fellow PostgreSQL extension authors and core developers. A brief report.

In addition to the afore-blogged Extension Summit, I also attended a slew of the regular PGConf.dev sessions, gave a talk on the future of the extension ecosystem, socialized with extension authors and core developers, and joined discussions in a number of unconference sessions. Some notes on selected talks and events:

Sessions

I enjoyed The road to new SQL/JSON features, where Álvaro Herrera gave a brief history of SQL/JSON in Postgres, starting with the JSON type in 9.2 (2012), JSONB in 2014, and SQL standard jsonpath in Postgres 12 (2017). Getting the SQL/JSON syntax finished turned out to be substantially more difficult, thanks to parsing issues. It took many attempts and a couple of reversions before most of the functionality was completed last year and included in Postgres 16. The forthcoming Postgres 17 finishes the work, with the standard fully supported except for “the JSON_TABLE plan param and json simplified accessor.”

It’s a great time to use Postgres for JSON object storage and management.

In Anarchy in the Database, subtitled “A Survey and Evaluation of Database Management System Extensibility”, Abigale Kim described her Master’s thesis work investigating Postgres extension incompatibilities. Installing and running tests for pairs of extensions, she found a number of conflicts and issues, such as a bug when Citus was paired with auto_explain (fixed in May). In all, 17% of pairs failed! Abi also found that 19% of extensions contain code copied from the Postgres core; page_inspect is 75% copied code!

Abi advocates for adding an extension manager into core, with well-defined hooks to manage extension load order and to streamline enabling and disabling extensions. Very interesting research, highlighting the need to think more deeply about how best to enable and empower the extension ecosystem.

Jeff Davis and Jeremy Schneider gave a thorough overview of Collations from A to Z. The problem rose to wide attention about six years ago when an libc upgrade changed a collation, leading to data loss, crashes, and duplicate primary keys. Ideally, sort orders would never change. But humans gotta human, language will evolve, and the order of things will need to be updated. In such situations, one must be aware of the changes and reindex or rebuild all indexes (and replace hot standbys, which can’t be reindexed).

I very much appreciated the context, as the ongoing issue with collations and upgrades has confused me. Should application authors choose collations or should DBAs? The new [builtin] collation provider in PostgresSQL 17 tries tries to bridge the gap by supporting unchanging Unicode code-point collation ordering that’s reasonably meaningful to humans. But I also realize that, for some projects with no need for human sort ordering, the C collations is more than sufficient.

In her keynote, When Hardware and Databases Collide, Margo Seltzer offered a provocation: Could PostgreSQL adopt something like CXL to scale to a virtually infinite pool of memory? Could one build a “complete fabric of CXL switches to turn an entire data center into a database”? I have no idea! It sure sounds like it could enable gigantic in-memory databases.

Tricks from in-memory databases by Andrey Borodin mostly went over my head, but each of the experiments sped things up a few percentage points. Together they might add up to something.

The Making PostgreSQL Hacking More Inclusive panel was terrific, and much-needed. I’m grateful that Amit Langote, Masahiko Sawada, and Melanie Plageman shared their experiences as up-and-coming non-white-male committers. I think the resulting discussion will help drive new inclusion initiatives in the PostgreSQL community, such as session moderator Robert Haas’s recently-announced Mentoring Program for Code Contributors.

Oh, and I gave a talk, The future of the extension ecosystem, in which I expanded on my mini-summit talk to suss out the needs of various members of the extension ecosystem (authors, users, DBAs, industry) and our plans to meet those needs in PGXN v2. Links:

Video PDF PDF with Notes Keynote Unconference

I also participated in the Friday Unconference. Abi, Yurii, and I led a discussion on Improving extensions in core. We discussed the need for an ABI stability policy, extension management, smoke testing (including for conflicts between extensions), a coalition to advocate for extensions in core (since launched as the Postgres Extension Developers Coalition), inline extensions, WASM-based extensions, and server installation immutability. Great discussions and a few actionable outcomes, some of which I’ve been working on. More soon in future posts.

In Increase Community Participation, we talked about the challenges for broadening the PostgreSQL contributor community, attracting and retaining contributors, recognizing contributions, and how to address issues of burnout and allow people to “retire”. I joined the discourse on how we could adopt or at least support GitHub workflows, such as pull requests, to encourage more patch review in a familiar environment. Personally, I’ve been creating pull requests in my fork for my patches for this very reason.

We also touched on training and mentoring new contributors (hence the mentoring announcement) and changes to postgresql.org, notably adding dedicated pages for each project governance committee, especially for the Contributors Committee (there’s a Contributors Committee?), as well as information for how to become a contributor and be listed on the contributor page.

Final Thoughts

I attended PGCon from 2009 to 2014, and always enjoyed the commearderie in Ottawa every year. Most people went to the same pub after sessions every night (or for some part of each evening), where random connections and deep technical nerdery would continue into the small hours, both indoors and out. The Black Oak was a highlight of the conference for me, every year.

In the intervening years I got busy with non-Postgres work and scaled back my participation. I finally returned in 2023 (other than a virtual unconference in 2022), and found it much the same, although the Black Oak had closed, and now there were 2-3 where people went, diluting the social pool a bit — though still a highlight.

As the new iteration of the Postgres Developer Conference, PGConf.dev is a worthy successor. Vancouver was a nice city for it, and people bought the same energy as always. I connected with far more people, and more meaningfully, than at any other conference. But other than the reception and dinner on Wednesday, there was no one (or three) place where people tended to aggregate into the wee hours. Or at least I wasn’t aware of it. The end of PGCon is bittersweet for me, but I’m happy to continue to participate in PGCONf.dev.

See you next year!

A startup on hard mode: Oxide, Part 2. Software & Culture

Oxide is a hardware and a software startup, assembling hardware for their Cloud Computer, and building the software stack from the ground up. A deep dive into the company’s tech stack & culture.

👋 Hi, this is Gergely with a subscriber-only issue of the Pragmatic Engineer Newsletter. In every issue, I cover challenges at Big Tech and startups through the lens of engineering managers and senior engineers. To get articles like this in your inbox, every week, subscribe:

Subscribe now

Before we start: we are running research on bug management and “keep the lights on” (KTLO.) This is an area many engineering teams struggle with, and we’d love to hear what works for you, and your organization. You can share details here with us – with Gergely and Elin, that is. Thank you!

Hardware companies are usually considered startups on “hard mode” because hardware needs more capital and has lower margins than software, and this challenge is shown by the fact there are far fewer hardware startup success stories than software ones. And Oxide is not only building novel hardware – a new type of server named “the cloud computer” – but it’s also producing the software stack from scratch.

I visited the company’s headquarters in Emeryville (a few minutes by car across the Bay Bridge from San Francisco) to learn more about how Oxide operates, with cofounder and CTO Bryan Cantrill.

In Part 1 of this mini-series, we covered the hardware side of the business; building a networking switch, using “proto boards” to iterate quickly on hardware, the hardware manufacturing process, and related topics. Today, we wrap up with:

Evolution of “state-of-the-art” server-side computing. Mainframes were popular in the 1960s-70s, and since the 2000s, PC-like servers have taken over data centers, while hyperscalers like Google and Meta build their own custom server hardware.

Software stack. Built from the ground up with Rust, an open source operating system, debugger, and utilities. Also a hypervisor based on bhyve, Typescript, CockroachDB, and other technologies.

Compensation & benefits. Nearly everyone makes the same base salary of $201,227, except salespeople with incentives. It’s a rare compensation strategy that may not work forever, but does now!

Hiring process. A writing-heavy process that showcases how important effective writing and analysis are. Interestingly, everyone sees each other’s “work sample” packages.

Engineering culture. Remote-first, writing-heavy, RFDs, recorded meetings, no performance reviews, and more. 

Software and hardware engineering collaboration. At most companies, software engineers have to accept that hardware is unchangeable, and hardware engineers accept the same about software. But when software and hardware engineers truly communicate, they realize neither is true, and they can change everything and anything, as Oxide has done so.

Impact of Apple and Sun. Apple is the best-known consumer tech company which makes its own hardware and software, while Sun was the last major server maker of this type. Bryan worked at Sun for 14 years and Oxide follows a similar playbook to that which made Sun successful in the 1990s.

As always, these deep dives into tech companies are fully independent, and I have no commercial affiliation with them. I choose businesses to cover based on interest from readers and software professionals, and also when it’s an interesting company or domain. If you have suggestions for interesting tech businesses to cover in the future, please share

1. Evolution of “state-of-the-art” server-side computing

In Part 1, we looked at why Oxide is building a new type of server, and why now in 2024? After all, building and selling a large, relatively expensive cloud computer as big as a server rack seems a bit of a throwback to the bygone mainframe computing era.

The question is a good opportunity to look at how servers have evolved over 70 years. In a 2020 talk at Stanford University, Bryan gave an interesting overview. Excerpts below:

1961: IBM 709. This machine was one of the first to qualify as a “mainframe,” as it was large enough to run time-shared computing. It was a vacuum tube computer, weighed 33,000 pounds (15 tonnes,) and occupied 1,900 square feet (180 sqm,) consuming 205 KW. Today, a full rack consumes around 10-25 KW. Add to this the required air conditioning, which was an additional 50% in weight, space and energy usage!

1975: PDP 11-70. Machines were getting smaller and more powerful.

1999: Sun E10K. Many websites used Sun servers in the late 1990s, when the E10K looked state-of-the-art. eBay famously started off with a 2-processor Sun machine, eventually using a 64-processor, 64GB Sun E10K version to operate the website.

2009: x86 machines. In a decade, Intel x86, Intel’s processor family won the server battle with value for money; offering the same amount of compute for a fraction of the price of vendors like Sun. Around 2009, HP’s DL380 was a common choice.

The HP DL380 Gen 5 rack-mount, manufactured 2007-2009.

Initially, x86 servers had display ports CD-ROM drives, which was odd on a server. The reason was that it was architecturally a personal computer, despite being rack-mounted. They were popular for the standout price-for-performance of the x86 processor.

2009: hyperscale computing begins at Google. Tech giants believed they could have better servers by custom-building their own server architecture from scratch, instead of using what was effectively a PC.

Google aimed to build the cheapest-possible server for its needs, and optimized all parts of the early design for this. This server got rid of unneeded things like the CD-drive and several ports, leaving a motherboard, CPUs, memory, hard drives, and a power unit. Google kept iterating on the design.

2017: hyperscale computing accelerates. It wasn’t just Google that found vendors on the market didn’t cater for increasingly large computing needs. Other large tech companies decided to design their own servers for their data centers, including Facebook:

The Facebook Tioga Pass design. This was its custom-designed and built compute sled. Source: Facebook

By then, hyperscale compute had evolved into compute sleds with no integrated power supply. Instead, they plugged into a DC bus bar. Most hyperscalers realized that optimizing power consumption was crucial for building efficient, large-scale compute. Bryan says:

“When your goal is to improve your power usage effectiveness, you want to be as efficient as possible and have all of your power go to your computing, and as little as possible to heating the room.”

2020: server-side computing still resembles 2009. As hyperscale computing went through a major evolution in a decade, a popular server in 2020 was the HPE DL560:

The HPE DL560 Gen10 looks similar to the HP DL380 Gen 5 from a decade earlier

It remains a PC design and ships with a DVD drive and display ports. Bryan’s observation is that most companies lack the “infrastructure privilege” to use their custom-built solutions, unlike hyperscalers such as Google and Meta which greatly innovated in server-side efficiency.

Why has there been no innovation in modernizing the server, so that companies can buy an improved server for large-scale use cases? Bryan says:

“Actually, there have been many, many attempts at innovating hardware within the cloud. Attempts occurred at established companies, like Intel’s attempt with the Intel Rack Scale Design (2017) or HP’s HPE Moonshot (2013). Startups like Nebula (2011-2015) and Skyport (2013-2018, acquired by Cisco) also tried to solve this problem.

Each attempt fell short for its own reasons, but the common theme I see is that they were either insufficiently ambitious, or insufficiently comprehensive – and sometimes both.

Solving the problem of building a new type of cloud computing building block requires both hardware and software, and they must be co-designed. For established players, doing this is simply too disruptive. They would rather reuse their existing hardware and software stack! And for startups, it is too capital-intensive, as the cost of building both hardware and software from scratch is just too large.”

2. Software stack

Rust is Oxide’s language of choice for the operating system and backend services. Software engineer Steve Klabnik was previously on Rust’s core team, and joined Oxide as one of the first software engineers. On the DevTools.fm podcast, he outlined reasons why a developer would choose Rust for systems programming, over C or C++:

“Rust allows you to do everything C and C++ does, but it helps you do those tasks significantly more. If you're doing low-level work, you have to use very sharp tools and sharp tools can sometimes cut you. And there's like a weird balance there. 

Additionally this low-level space hasn't really seen a lot of new programming languages in a long time. So these other languages tend to be much more old-school – therefore harder to use – if you weren’t doing them since the 90s.

Rust brings a 2010s-era development experience to a space that is pretty solidly stuck in the 70s and 80s. There’s a lot of people who don’t really care about the Rust versus C++ language, but that there is a developer experience that is more familiar to them, makes Rust worthwhile.”

Interestingly, going all-in on Rust greatly helped with hiring, Bryan reveals; probably as a combination of the Rust community being relatively small, and Oxide being open about its commitment to it. Initially, it was more challenging to find qualified hardware engineers than software engineers; perhaps because software engineers into Rust heard about Oxide.

Open source is a deliberate strategy for Oxide’s builds and software releases, and another differentiator from other hardware vendors who ship custom hardware with custom, closed source software. 

The embedded operating system running on the microcontrollers in Oxide’s hardware is called Hubris. (Note that this is not the operating system running on the AMD CPUs: that operating system is Helios, as discussed below.) Hubris is all-Rust and open source. Characteristics:

Microkernel-based: it uses the near-minimum amount of software to implement an operating system.

A memory-protected system: tasks, the kernel, and drivers, all in disjoint protection domains. Separation is important, even when using a memory-safe language like Rust.

A highly debuggable operating system, thanks to a dedicated debugger called Humility.

Static for application execution and application payload. Many operating systems create tasks dynamically, at runtime. but Hubris was designed to specify tasks for a given application in build time. Bryan says: 

“This is the best of both worlds: it is at once dynamic and general purpose with respect to what the system can run, but also entirely static in terms of the binary payload of a particular application — and broadly static in terms of its execution. Dynamic resource exhaustion is the root of many problems in embedded systems; having the system know a priori all of the tasks that it will ever see, liberates it from not just a major source of dynamic allocation, but also from the concomitant failure modes.”

If you want to run Hubris on actual hardware and debug it with Humility, you can by ordering a board that costs around $30: the ST Nucleo-H753ZI evaluation board is suitable:

Oxide’s OS runs on Oxide hardware and smaller boards like the ST Nucleo-H753ZI

The hypervisor. A hypervisor is important software in cloud computing. Also known as a “Virtual Machine Monitor (VMM),” the hypervisor creates and runs virtual machines on top of physical machines. Server hardware is usually powerful enough to warrant dividing one physical server into multiple virtual machines, or at least being able to do this.

Oxide uses a hypervisor solution built on the open source bhyve, which is itself built into illumos, a Unix operating system. Oxide maintains its own illumos distribution called Helios and builds its own, Rust-based VMM userspace, called Propolis. Oxide shares more about the hypervisor’s capabilities in online documentation.

Oxide has also open sourced many other pieces of software purpose-built for their own stack, or neat tools: 

Omicron: Oxide’s rack control plane. Read more about its architecture.

Crucible: Oxide’s distributed storage service

Bootleby: a minimal, general bootloader

Design-system: base frontend components used across Oxide clients

OPTE: Oxide’s packet transformation engine

Dropshot: exposing REST APIs from a Rust application

Typify: a JSON to Rust schema compiler

Console: the Oxide web console

…and many others!

Oxide web console, a web client to the Oxide API. See source code

Other technologies Oxide uses:

Typescript: the language of choice for everything frontend. The Oxide web console, design assets, and RFD site, use this language.

CockroachDB: the distributed database used for the control plane data storage system.

ClickHouse: the open source column-oriented database management system used to collect and store telemetry data for the Oxide Rack.

Tailwind CSS: the utility-first CSS framework to specify styles using markup, is used on websites built by the Oxide team.

Terraform: Oxide’s requests for discussion site uses Terraform to describe its underlying infrastructure using infrastructure-as-code, to specify the Google Cloud zone this site runs from. This is more of an internal infrastructure choice – and a rather simple one – but I find it interesting.

Figma: used for design mockups, and Oxide’s design system library syncs with Figma. Check out a deep dive into Figma’s engineering culture.

3. Compensation & benefits

Oxide chose a radically different compensation approach from most companies, with almost everyone earning an identical base salary of $201,227. The only exception is some salespeople on a lower base salary, but with commission.

How did this unusual setup emerge? Bryan shares that the founders brainstormed to find an equitable compensation approach which worked across different geographies. Ultimately, it came down to simplicity, he says:

“We decided to do something outlandishly simple. Take the salary that Steve, Jess, and I were going to pay ourselves, and pay that to everyone. The three of us live in the San Francisco Bay Area, and Steve and I each have three kids; we knew that the dollar figure that would allow us to live without financial distress – which we put at $175,000 a year – would be at least universally adequate for the team we wanted to build. And we mean everyone: as of this writing we have 23 employees, and that’s what we all make.”

This unusual approach supports company values:

Teamwork: “The need to quantify performance in order to justify changes to compensation is at the root of much of what’s wrong in the tech industry; instead of incentivizing people to achieve together as a team, they are incentivized to advance themselves.”

Equitability: the founders treat people as they wish to be treated, and identical salaries mean no negotiations.

Transparency: Colleagues know how much each other earn, so a potentially tricky topic is neutered.

The company updates the base salary annually to track inflation: in 2024, everyone makes $201,227. Bryan acknowledged this model may not scale if Oxide employs large numbers of people in the future, but he hopes the spirit of this comp approach would remain.

Other benefits. Oxide offers benefits on top of salary – mostly health insurance; very important in the US:

Medical, dental and vision insurance in the US. 100% paid for employees and dependents.

Optional FSA plan for out-of-pocket healthcare and dependent care expenses.

Reimbursing up to $17,000 annually for various surgery expenses

Retirement plan (401K)

Medical coverage for non-US remote folks

In another example of transparency, the policy documentation for these benefits was made public in 2022 in a blog post by systems engineer, iliana etaoin.

4. Heavyweight hiring process

Oxide’s hiring process is unlike anything I’ve seen, and we discussed it with the team during a podcast recording at their office.

The CBOR Web Token (CWT) Claims in COSE Headers specification has been published as RFC 9597! This closes a gap for COSE relative to JOSE, adding the ability to use CWT claims in COSE header parameters, just as JWT claims can be used in JOSE header parameters.

The specification abstract is:

This document describes how to include CBOR Web Token (CWT) claims in the header parameters of any CBOR Object Signing and Encryption (COSE) structure. This functionality helps to facilitate applications that wish to make use of CWT claims in encrypted COSE structures and/or COSE structures featuring detached signatures, while having some of those claims be available before decryption and/or without inspecting the detached payload. Another use case is using CWT claims with payloads that are not CWT Claims Sets, including payloads that are not CBOR at all.

Special thanks to my co-author Tobias Looker, who had a use case for this functionality and wrote an RFC with me defining it (his first!). It was a pleasure working with Tobias on the draft as we navigated the ins and outs of working group feedback and IETF processes. The spec was refined by the journey we took together. And as with CBOR Object Signing and Encryption (COSE) “typ” (type) Header Parameter (now RFC 9596) that immediately preceded it, I believe the CBOR and COSE ecosystems are better for it.

Making Bubbles

About a year ago, I wrote about a new concept I’d started to develop: a new way to look at how we view account provisioning, and how we use federation technologies, especially in a world where the connection properties are always changing.

About a year ago, I wrote about a new concept I’d started to develop: a new way to look at how we view account provisioning, and how we use federation technologies, especially in a world where the connection properties are always changing. I called this idea federation bubbles, and in the last year I’ve been privileged to talk to a lot of people about this idea and what it could mean, and I’ve even been able to prototype out some key pieces of the puzzle. I’ve gotten to present the idea at a few conferences, and I even recently did a whole podcast episode on the topic (with a video version!) for Identity At The Center.

Through all of that, several major concepts have risen to the surface, and I’ll be looking to tackle these in a few different posts — questions like “can’t we just copy the user store?” and “isn’t this just like an interfederation?” get brought up quickly each time. But I wanted to start with something very concrete before getting into the what and why: how would you make a bubble?

It’s Not New Technology

The central idea behind a bubble in this world is that it’s an internally-cohesive network of systems, with clear boundaries and processes to cross those boundaries. I think we can start building bubbles today out of tech that we’re already using for similar and related purposes.

Some of the technologies we can make bubbles out of

An important corollary to that is that I deeply believe that this concept is not conducive to a single technology stack. So many times through tech history, we’ve been told that if the whole world would just adopt this one particular way of doing things, then all the problems would be solved. This line is usually delivered by a person selling the new way of doing things, or at the very least the picks and shovels to make it happen.

For bubbles, though? I think we’ve got all the most important parts already. What’s fundamentally different is how we use everything, and the assumptions we make around the moving parts and how we stick them together.

Crossing The Borders

In order to create and update accounts in the bubble, we often want to pull that information from elsewhere. Whether it’s an authoritative source that created the bubble in the first place, or it’s a peer we’re bumping up against in the field, we want to be able to copy identifiers and other attributes into our local account.

For the more structured cases, SCIM gives us a really powerful system for propagating user objects across systems. X.509 certificates and Verifiable Credentials also give us a way to carry a stack of user information into our system, while also providing a convenient key-proofing mechanism with the delivery.

But not everything is that structured, since we’ll also want to be talking to peers in the field about their accounts. We need to be able to do this without going all the way back up our peer’s hierarchy, and so we can do just-in-time provisioning based on a federation protocol as needed.

When that stack of user attributes gets to us, it becomes an input into an account management system — but just one input among potentially many. Instead of just overwriting or overriding a record we might already have, the incoming information feeds into the account in a way that makes sense for the local environment.

When we need to send updates about changes to others in the system, the shared signals and events frameworks give us a really solid base to build on. But what SSE, CAEP, and RISC are missing is a semantic layer that can talk about the kinds of dynamic accounts in distributed systems that we expect in a bubble environment.

It’s Familiar on the Inside

Within a bubble, everything is local. Because of that, we want to have a clear notion of a single account for each user. We can use federation technology like OpenID Connect (and the OAuth 2 it’s built on) to connect that one account to a variety of applications, devices, APIs, and whatever the bubbled system needs. This is a wholly separate federation protocol from the onboarding and outward facing processes we talked about above. We can also use SCIM to transmit internal user attributes and updates proactively, or we can just rely on the federation transactions to carry good-enough propagation of these attributes to our apps.

We aren’t going to be using external federation or similar technologies once the onboarding has taken place. For logging in to the IdP itself, we really should be using passkeys everywhere. Since we control the onboarding process, we get to control how we associate the accounts with the authenticators. Sometimes, this means we’ll hand someone their shiny new authenticator at the moment we make their account active. Sometimes, we’ll have them plug it in and bind it when we set things up. Sometimes, a record of their authenticator might come across the wire with them.

And if we’ve got applications, users, or circumstances that make some authenticators unworkable sometimes? Since the account is local, we have the ability to manage this in a way that makes sense in our environment. For example, a firefighter wearing heavy gloves is not going to be able to use a fingerprint reader in the field, but they could probably use one when back at HQ, not to mention all of the other users in the system that don’t have the same constraints. In other words, we can adapt as we need to because we are close to the environment that requires the adaptation.

Addressing The World

As we collect information about an account, we need to record not only what the information is, but also where we got it. Our view of that account is the amalgamation of all of our information sources, plus all of the local information about that account. In order for this view to make sense, we need to have a reasonable way to talk about where something came from.

Traditional federation models like to use hostnames for this, but not everything in our environment is going to be addressable on a stable, publicly-accessible URL. We can’t rely on a common data fabric (e.g., assuming everyone uses the same blockchain), and we can also be pretty sure that keys will change over time for different parties and circumstances, so we can’t just use the keys directly when we need a record.

OpenID Connect Federation brings a solution that works well for the online, connected world, but would need to be adapted for a space where the federation domains and their availability are much more dynamic. The SPIFFE project also brings us the concept of trust bundles, which tie a set of keys to identifiers in a way that can be passed between different domains. While not an exact analogue to the more macro problem here, there are some key similarities to what we’re seeing in the workload space.

Pulling it Together

The final solution isn’t going to be a single protocol, or even a single technology stack. Interoperability in this space is going to be defined by a complicated and contextual set of decisions. Two bubbles might not always be able to talk in a given dimension — one might speak OIDC outbound and another might only take in VC’s — but it’s going to be important that they can still speak in other dimensions. In the end, it’s people that make the technologies work, and we need to embrace the dirt and uncertainty of the world if we want any hope of surviving in it.

Does personal AI require Big Compute?

I don’t think it does. Not for everything.

We already have personal AI for autocomplete. Do we need Big Compute for a personal AI to tell us which pieces within our Amazon orders are in which line items in our Visa statements? (Different items in a shipment often appear inside different charges on a card.) Do we need Big Compute to tell us who we had lunch with, and where, three Fridays ago? Or to give us an itemized list of all the conferences we attended in the last five years? Or what tunes or podcasts we’ve played (or heard) in the last two months (for purposes such as this one)?

Let’s say we want a list of all the books on our shelves using something like OpenCV to detect text in natural scene images using the EAST text detector? Or to use the same kind of advanced pattern recognition to catalog everything we can point a phone camera at in our homes? Even if we need to hire models from elsewhere to help us out, onboard compute should be able to do a lot of it, and to keep our personal data private.

Right now your new TV is reporting what you watch back to parties unknown. Your new car is doing the same. Hell, so is your phone. What if you had all that data? Won’t you be able to do more with it than the spies and their corporate customers can?

It might be handy to know all the movies you’ve seen and series you’ve binged on your TV and other devices—including, say, the ones you’ve watched on a plane. And to remember when it was you drove to that specialty store in some other city, what the name of it was, and what was the good place you stopped for lunch on the way.

This data should be yours first—and alone—and shared with others at your discretion. You should be able to do a lot more with information gathered about you than those other parties can—and personal AI should be able to help you do it without relying on Big Compute (beyond having its owners give you back whatever got collected about you).

At this early stage in the evolution of AI, our conceptual frame for AI is almost entirely a Big Compute one. We need much more thinking out loud about what personal AI can do. I’m sure the sum of it will end up being a lot larger than what we’re getting now from Big AI.

Can you summarize your recent research into a single sentence?

That was the emailed request.

“Tagged archetypal cybernetic avatars team up to forage for contextualized information (qualia) in interdimensional “space” and bring it back to be collectively processed (composted?) in a globally-networked “gut brain.” This novel “brain,” managed through precision nutrition, uses quorum sensing and token-engineered consensus (Ethereum’s Consensys) to adjust a shared topological game board, which in turn performs some collective calculation or puzzle solving task that appears to have been delegated to us, as a highly-evolved distributed intelligence, from a source outside our shared layer of space/time.”

Ok, I ended up breaking into into two sentences, because the first run-on attempt was just too tricky.

The requestor didn’t understand my response.

I cannot insert the knowledge of my unique lived experience into any person’s consciousness, nor would I want that. Everyone has a road of discovery to walk. I’m not done with my journey yet, so don’t pressure me to commit to one final theory of what is happening.

The video below describes a recent visit I made to a botanic garden on Lake Hamilton just south of Hot Springs, Arkansas. There I encountered a steampunk squirrel sculpture in a $1.8 million “children’s treehouse” on a former tract of cut-over timber.

My assessment is that the mountain-climbing adventure squirrel and his sidekick the skydiving cardinal are encoded artefacts. When examined (mentally unlocked like the bronze acorns in the squirrel’s satchel and around the tree trunk) with curiosity in the larger context of information flows from a podcast shared with me earlier that day, a view opened onto a vast landscape of ideas about information theory, choice, the social physics of self-assembly, morphogenetic fields, and the realization of human potential.

My video concludes with a half hour where I discuss the ideas that welled up during that excursion and how they intersect with ASU astrobiologist Sara Walker’s recent conversation with Lex Fridman.

Poke around and see what you find in your corner of the world. I found deep time artefacts, synesthetic communication, and fairy houses sitting on quartz crystals.

Just a Theory

POC: Distributing Trunk Binaries via OCI

Would it be possible to distribute Postgres extension binaries via Open Container Registries? Tune in to find out!

A couple months ago, Álvaro Hernández suggested that Postgres extensions should be distributed as OCI (née Docker) images:

It’s all about not reinventing the wheel, and leveraging the ecosystem around OCI. Many of the problems (solutions) in building, packaging and distributing extensions are already solved by OCI: there’s a whole ecosystem of tools around OCI that provide additional benefits in terms of tooling, infrastructure and common knowledge.

As a relatively experienced Docker image builder and distributor, I found this idea intriguing. I wasn’t familiar with the OCI Image Manifest Specification, which defines how to build OCI images containing arbitrary files, or “artifacts”. But if we could adopt an existing protocol and federated registry system like OCI/Docker, it would save pretty significant development time over building our own — plus we’d be adopting and potentially contributing to a standard.

After PGConf.dev, I decided to see if I could work out how to distribute packages in the recently-proposed trunk format such that an OCI/Docker-style image URL could be used to install a version of an extension compiled for the appropriate architecture.

Thanks to the denizens of the #oras and #zot channels on the CNCF Slack, I extended the trunk format POC in pg-semver PR 69 to build the necessary JSON manifest files, push them to a registry, and then pull and install the architecturally-appropriate package. Here’s how it works.

Metadata generation

First, I extended trunk.mk, which builds a trunk package, with a few more targets that create the JSON files with metadata necessary to build OCI manifests. The files that make trunk now also generates are:

{extension}_annotations.json OCI standard annotations describing a package, including license, vendor, and URLs. The semver_annotations.json file looks like this: { "org.opencontainers.image.created": "2024-06-20T18:07:24Z", "org.opencontainers.image.licenses": "PostgreSQL", "org.opencontainers.image.title": "semver", "org.opencontainers.image.description": "A Postgres data type for the Semantic Version format with support for btree and hash indexing.", "org.opencontainers.image.source": "https://github.com/theory/pg-semver", "org.opencontainers.image.vendor": "PGXN", "org.opencontainers.image.ref.name": "0.32.1", "org.opencontainers.image.version": "0.32.1", "org.opencontainers.image.url": "https://github.com/theory/pg-semver" } {package_name}_config.json An object with fields appropriate for OCI platform specification, plus the creation date. Here are the content of semver-0.32.1+pg16-darwin-23.5.0-arm64_config.json: { "os": "darwin", "os.version": "23.5.0", "architecture": "arm64", "created": "2024-06-20T18:07:24Z" } {package_name}_annotations.json An object defining annotations to use in an image, built for a specific platform, all under the special key $manifest to be used later by the ORAS CLI to put them in the right place. semver-0.32.1+pg16-darwin-23.5.0-arm64_annotations.json example: { "$manifest": { "org.opencontainers.image.created": "2024-06-20T18:07:24Z", "org.opencontainers.image.title": "semver-0.32.1+pg16-darwin-23.5.0-arm64.trunk", "org.opencontainers.image.licenses": "PostgreSQL", "org.opencontainers.image.description": "A Postgres data type for the Semantic Version format with support for btree and hash indexing.", "org.opencontainers.image.source": "https://github.com/theory/pg-semver", "org.opencontainers.image.vendor": "PGXN", "org.opencontainers.image.ref.name": "0.32.1", "org.opencontainers.image.version": "0.32.1", "org.opencontainers.image.url": "https://github.com/theory/pg-semver", "org.pgxn.trunk.pg.version": "16.3", "org.pgxn.trunk.pg.major": "16", "org.pgxn.trunk.pg.version_num": "160003", "org.pgxn.trunk.version": "0.1.0" } }

The org.opencontainers.image keys are the same as in semver_annotations.json, while the new org.pgxn.trunk annotations are intended for an install client to find the image appropriate for the version of Postgres, although that functionality isn’t part of this POC.

The only change to the Makefile to support these annotations are the addition of a DESCRIPTION variable to populate org.opencontainers.image.description and a REPO_URL to populate org.opencontainers.image.source. trunk.mk includes a couple other new variables, too: TITLE (defaults to EXTENSION), VENDOR (defaults to “PGXN”), and URL (defaults to REPO-URL).

Publishing Images

The new shell script push_trunk uses the ORAS CLI and jq to build the necessary manifest files and push them to an OCI registry. It currently works only two trunk files like those built in the trunk POC. It first “pushes” the trunks to a locally-created OCI layout, then constructs manifests associated the SHA ID of each just-pushed image with annotations and platform configurations and writes them into an image index manifest. Finally, it pushes the complete OCI layout described by the index to a remote registry.

If that sounds like a lot of steps, you’re right, it adds up. But the result, following a precedent established by Homebrew (as described in this issue) is multiple images for different platforms indexed at a single URI. Once we publish the two trunks:

./push_trunk localhost:5000/theory/semver:0-32.1 \ semver-0.32.1+pg16-darwin-23.5.0-arm64 \ semver-0.32.1+pg16-linux-amd64

We can fetch the manifests. The address for the image index is that first parameter, localhost:5000/theory/semver:0-32.1; we fetch the manifest with the command

oras manifest fetch localhost:5000/theory/semver:0-32.1

Which returns:

{ "schemaVersion": 2, "mediaType": "application/vnd.oci.image.index.v1+json", "manifests": [ { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 1285, "digest": "sha256:1a14997eb380f9641cba6193c001eb630319f345d76ef07aee37f86fafcdbe0b", "platform": { "os": "linux", "architecture": "amd64" }, "annotations": { "org.pgxn.trunk.pg.version": "16.3", "org.pgxn.trunk.pg.major": "16", "org.pgxn.trunk.pg.version_num": "160003", "org.pgxn.trunk.version": "0.1.0" } }, { "mediaType": "application/vnd.oci.image.manifest.v1+json", "size": 1302, "digest": "sha256:385fcfe6b33c858c3f126fb4284afe23ba8c2f7c32db8a50a607dfece6dd9162", "platform": { "os": "darwin", "os.version": "23.5.0", "architecture": "arm64" }, "annotations": { "org.pgxn.trunk.pg.version": "16.3", "org.pgxn.trunk.pg.major": "16", "org.pgxn.trunk.pg.version_num": "160003", "org.pgxn.trunk.version": "0.1.0" } } ], "annotations": { "org.opencontainers.image.created": "2024-06-21T13:55:01Z", "org.opencontainers.image.licenses": "PostgreSQL", "org.opencontainers.image.title": "semver", "org.opencontainers.image.description": "A Postgres data type for the Semantic Version format with support for btree and hash indexing.", "org.opencontainers.image.source": "https://github.com/theory/pg-semver", "org.opencontainers.image.vendor": "PGXN", "org.opencontainers.image.ref.name": "0.32.1", "org.opencontainers.image.version": "0.32.1", "org.opencontainers.image.url": "https://github.com/theory/pg-semver" } }

Note the manifests array, which lists images associated with this URI. The first one is for amd64 linux and the second for arm64 darwin. They also contain the org.pgxn.trunk annotations that would allow filtering for an appropriate Postgres version. The idea is to download an index like this, find the manifest information for the appropriate platform and Postgres version, and download it. To get the darwin image, pull it by its digest:

oras pull localhost:5000/theory/semver:0-32.1@sha256:385fcfe6b33c858c3f126fb4284afe23ba8c2f7c32db8a50a607dfece6dd9162

Which downloads the file:

$ ls -l *.trunk semver-0.32.1+pg16-darwin-23.5.0-arm64.trunk

Nice! The OCI protocol allows for filtering on platform directly, skipping the need to download and examine the image index. This is how docker pull --platform works, but is general to OCI. We can fetch a manifest with this command:

oras manifest fetch --platform linux/amd64 localhost:5000/theory/semver:0-32.1

Which returns not the image index, but the manifest for the Linux image:

{ "schemaVersion": 2, "mediaType": "application/vnd.oci.image.manifest.v1+json", "artifactType": "application/vnd.pgxn.trunk.layer.v1", "config": { "mediaType": "application/vnd.oci.image.config.v1+json", "digest": "sha256:90c8d6f2e67cba09f8178648ad95a6b31e51c0d902058bf396f9e7e5f50c8dfd", "size": 84 }, "layers": [ { "mediaType": "application/vnd.oci.image.layer.v1.tar+gzip", "digest": "sha256:b52b292cabe3ca479673ab68d3ea647802a86f15059c3e19ed24d5a7688159c3", "size": 61983, "annotations": { "org.opencontainers.image.title": "semver-0.32.1+pg16-linux-amd64.trunk" } } ], "annotations": { "org.opencontainers.image.created": "2024-06-21T17:55:13Z", "org.opencontainers.image.description": "A Postgres data type for the Semantic Version format with support for btree and hash indexing.", "org.opencontainers.image.licenses": "PostgreSQL", "org.opencontainers.image.ref.name": "0.32.1", "org.opencontainers.image.source": "https://github.com/theory/pg-semver", "org.opencontainers.image.title": "semver-0.32.1+pg16-linux-amd64.trunk", "org.opencontainers.image.url": "https://github.com/theory/pg-semver", "org.opencontainers.image.vendor": "PGXN", "org.opencontainers.image.version": "0.32.1", "org.pgxn.trunk.pg.major": "16", "org.pgxn.trunk.pg.version": "16.3", "org.pgxn.trunk.pg.version_num": "160003", "org.pgxn.trunk.version": "0.1.0" } }

Or we can pull the file by platform with:

rm *.trunk oras pull --platform linux/amd64 localhost:5000/theory/semver:0-32.1

And now the Linux image has been downloaded:

$ ls -1 *.trunk semver-0.32.1+pg16-linux-amd64.trunk

Pretty nice! These examples use zot running in a local Docker container, but could just as easily use the Docker registry (docker.io) or the GitHub registry (ghcr.io) — which is where Homebrew stores its images (e.g., sqlite 3.46.0).

Installation

With these manifests configured and pushed, changes to install_trunk use this knowledge to download from the registry instead of relying on an existing file (as implemented for the trunk POC). Now we call it like so:

./install_trunk localhost:5000/theory/semver:0-32.1

First, it assembles platform information from uname, then pulls the platform-specific image with this oras command:

oras pull --no-tty --plain-http \ --format 'go-template={{(first .files).path}}' --platform "$platform" "$trunk"

As before, it downloads the image appropriate for the platform. The --format option, meanwhile, causes it to also download annotations and extract the path for the downloaded file. So in addition to downloading the file, it also emits its full path:

/tmp/pgxn/semver-0.32.1+pg16-darwin-23.5.0-arm64.trunk

the script proceeds to unpack the image with that file name and continues with the installation process as before.

Demo

The last new file in the PR is docker_compose.yml, which sets up an amd64 Linux container for building an extension for Postgres 16, and a zot container to push to and pull from. I used it to build this POC and record this demo:

To use it yourself, run these commands with docker_compose.yml:

git clone https://github.com/theory/pg-semver.git cd pg-semver git checkout -b trunk-oci origin/trunk-oci docker compose up -d

This clones the pg-semver repository, checks out the trunk-oci branch, fires up the containers. Wait a couple minutes for Postgres to start and be configured, then, assuming you can build against Postgres 16 on your local machine, you can follow the same steps. The commands in the demo are:

make trunk docker compose exec linux bash make clean make trunk exit ls -1 *.trunk ls -1 *.json ./push_trunk localhost:5000/theory/semver:0.32.1 \ semver-0.32.1+pg16-darwin-23.5.0-arm64 \ semver-0.32.1+pg16-linux-amd64 ./install_trunk localhost:5000/theory/semver:0.32.1 docker compose exec linux bash ./install_trunk zot:5000/theory/semver:0.32.1 exit

You might need to adjust the first trunk image name if your local configuration is not the same as mine.

Concept Proven

Honestly, this POC far exceeded my expectations. It worked great! Not only does the trunk format seem to work well, but distributing via OCI registries is even better! It brings a bunch of benefits:

We could build a community registry that automatically builds images for PGXN releases for a variety of platforms. This could grow to become the default method for installing extensions, perhaps via a command such as pgxn trunk install theory/semver. Anyone can use any other registry, and the tooling will work with it. Just as you can pull Docker images from docker.io, you can also pull them from ghcr.io, quay.io, or any other OCI-compliant registry. The same applies here. Extension authors can build and publish trunks to their own registries if they like. Better yet, organizations can build extension registries for their own use cases, to complement the community registry. Think internal registries for private extensions, or commercial registries that additional features, such as security scans or curation.

Super promising! I’m just about ready to get to work building this stuff, though I anticipate a few challenges:

We’ll need a way to find the latest version (tag) of a release. I’m sure this is do-able, since Homebrew does it. There must be some other index for tags (ghcr.io/homebrew/core/sqlite:latest doesn’t return a result, alas). In addition to filtering on platform specification when pulling an image, it would be nice to filter on other attributes, such as the org.pgxn.trunk annotations defining Postgres the version. For now it will be fine for the CLI to download an image index and find the right image, but additional server-side filtering would be very nice. Will need to support extensions that can run on any architecture, such as pure SQL extensions. I think this will be pretty easy by publishing a single tagged image instead of an image index. If we build a community registry, where should it be hosted? Homebrew uses ghcr.io, presumably avoiding hosting costs, but it might be nice to have a specific community registry, perhaps at trunk.pgxn.org or perhaps oci.postgresql.org. If we do host a registry, might we want to allow extension authors to publish their own trunks within their namespaces? How might that be organized?

I can imagine workable solutions to these relatively minor challenges. As long as we can encapsulate them into the commands for a single command-line client, it should work out well.

Can’t wait to get started. What do you think?

Just a Theory

POC: PGXN Binary Distribution Format

A proof of concept for “trunk”, the proposed binary distribution format for Postgres extensions.

In an effort to make discussion of PGXN and related improvements as accessible as possible, I’ve set up PGXN Discussions on GitHub. Of course GitHub created default categories for all sorts of conversation, and all is welcome, in accordance with the PostgresSQL Code of Conduct.

But I hope more people will be able to find, read, comment on, and even write their own RFCs than was possible on the Postgres Wiki or on Just a Theory. Therefore, please have a look at Proposal-2: Binary Distribution Format, which draws inspiration from the Python wheel format and Trunk to define a packaging format that allows for platform and PostgreSQL version matching to quickly install pre-compiled binary PostgreSQL extension packages.

The proposal has the details, but the basic idea is that files to be installed are stored in directories named for pg_config directory configurations. Then all an installer has to do is install the files in those subdirectories into the pg_config-specified directories.

POC

I ran this idea past some colleagues, and they thought it worth exploring. But the proposal itself didn’t feel sufficient. I wanted to prove that it could work.

So I created a proof-of-concept (POC) implementation in just about the quickest way I could think of and applied it to the semver extension in PR 68. Here’s how it works.

trunk.mk

A new file, trunk.mk, dupes all of the install targets from PGXS and rejiggers them to install into the proposed package directory format. The Makefile simply imports trunk.mk:

--- a/Makefile +++ b/Makefile @@ -22,6 +22,7 @@ endif PGXS := $(shell $(PG_CONFIG) --pgxs) include $(PGXS) +include ./trunk.mk all: sql/$(EXTENSION)--$(EXTVERSION).sql

And now there’s a trunk target that uses those packaging targets. Here’s its output on my amd64 Mac (after running make):

$ make trunk gmkdir -p 'semver-0.32.1+pg16-darwin-23.5.0-arm64/pgsql/share/extension' gmkdir -p 'semver-0.32.1+pg16-darwin-23.5.0-arm64/pgsql/share/semver' gmkdir -p

The trunk target compresses everything into the resulting trunk file:

$ ls -1 *.trunk semver-0.32.1+pg16-darwin-23.5.0-arm64.trunk

This should work the same everywhere PGXS works. Here’s the output in an amd64 Linux container1 mounted to the same directory:

Pretty much the same, as expected. Now we have two trunks:

$ ls -1 *.trunk semver-0.32.1+pg16-darwin-23.5.0-arm64.trunk semver-0.32.1+pg16-linux-amd64.trunk

The package name format is:

{package}-{version}+{pgversion}-{os}-{os_version}-{architecture}.trunk

Here you see the same package, version, and Postgres version, but then the OSes differ, macOS includes the optional OS version, and then the architectures differ. This will allow an install client to download the appropriate trunk.

Note the directories into which files are copied under a top-level directory with that format (without the .trunk extension):

SHAREDIR files go into pgsql/share DOCDIR files go into pgsql/doc PKGLIB files go into pgsql/pkglib

What else is there?

$ ls -lah semver-0.32.1+pg16-linux-amd64 total 64 -rw-r--r--@ 1 david staff 12K Jun 20 13:56 Changes -rw-r--r--@ 1 david staff 1.2K Jun 20 13:56 LICENSE -rw-r--r--@ 1 david staff 3.5K Jun 20 13:56 README.md -rw-r--r-- 1 david staff 3.2K Jun 20 13:56 digests drwxr-xr-x 5 david staff 160B Jun 20 13:56 pgsql -rw-r--r-- 1 david staff 1.1K Jun 20 13:56 trunk.json

Changes, LICENSE, README.md are simply copied from the source. The digests file contains checksums in the BSD digest format for every file in the package, aside from digests itself. Here are the first 3:

$ head -3 semver-0.32.1+pg16-linux-amd64/digests SHA256 (Changes) = 98b5e87b8dc71604df4b743b1d80ef2fe40d96809a5fbad2a89ab97584bd9c01 SHA256 (LICENSE) = ff48c81463d79e2a57da57ca1af983c3067e51a8ff84c60296c6fbf0624a0531 SHA256 (README.md) = 99f7c59f796986777f873e78f47f7d44f5ce2deee645b4be3199f0a08dedc22d

This format makes it easy to validate all the files and well as adjust and update the hash algorithm over time.

Finally, the trunk.json file contains metadata about the extension and the system and Postgres on which the system was built:

{ "trunk": "0.1.0", "package": { "name": "semver", "version": "0.32.1", "language": "c", "license": "PostgreSQL" }, "postgres": { "version": "16.3", "major": "16", "number": 160003, "libs": "-lpgcommon -lpgport -lselinux -lzstd -llz4 -lxslt -lxml2 -lpam -lssl -lcrypto -lgssapi_krb5 -lz -lreadline -lm ", "cppflags": "-I. -I./ -I/usr/include/postgresql/16/server -I/usr/include/postgresql/internal -Wdate-time -D_FORTIFY_SOURCE=2 -D_GNU_SOURCE -I/usr/include/libxml2 ", "cflags": "-Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Werror=vla -Wendif-labels -Wmissing-format-attribute -Wimplicit-fallthrough=3 -Wcast-function-type -Wshadow=compatible-local -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -Wno-format-truncation -Wno-stringop-truncation -g -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -fno-omit-frame-pointer -fPIC -fvisibility=hidden", "ldflags": "-L/usr/lib/x86_64-linux-gnu -Wl,-z,relro -Wl,-z,now -L/usr/lib/llvm-16/lib -Wl,--as-needed" }, "platform": { "os": "linux", "arch": "amd64" } }

The trunk proposal doesn’t specify the contents (yet), but the idea is to include information for an installing application to verify that a package is appropriate to install on a platform and Postgres version.

install_trunk

Now we have some packages in the proposed format. How do we install them? install_trunk script is a POC installer. Let’s take it for a spin on macOS:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 $ ./install_trunk semver-0.32.1+pg16-darwin-23.5.0-arm64.trunk Unpacking semver-0.32.1+pg16-darwin-23.5.0-arm64.trunk Verifying all checksums...Changes: OK LICENSE: OK README.md: OK pgsql/pkglib/bitcode/src/semver/src/semver.bc: OK pgsql/pkglib/bitcode/src/semver.index.bc: OK pgsql/pkglib/semver.dylib: OK pgsql/doc/semver/semver.mmd: OK pgsql/share/extension/semver.control: OK pgsql/share/semver/semver--0.3.0--0.4.0.sql: OK pgsql/share/semver/semver--0.30.0--0.31.0.sql: OK pgsql/share/semver/semver--0.21.0--0.22.0.sql: OK pgsql/share/semver/semver--0.32.1.sql: OK pgsql/share/semver/semver--0.10.0--0.11.0.sql: OK pgsql/share/semver/semver--0.13.0--0.15.0.sql: OK pgsql/share/semver/semver--0.31.1--0.31.2.sql: OK pgsql/share/semver/semver--0.31.2--0.32.0.sql: OK pgsql/share/semver/semver--unpackaged--0.2.1.sql: OK pgsql/share/semver/semver--0.12.0--0.13.0.sql: OK pgsql/share/semver/semver--0.17.0--0.20.0.sql: OK pgsql/share/semver/semver--0.2.1--0.2.4.sql: OK pgsql/share/semver/semver--0.16.0--0.17.0.sql: OK pgsql/share/semver/semver--0.22.0--0.30.0.sql: OK pgsql/share/semver/semver--0.20.0--0.21.0.sql: OK pgsql/share/semver/semver--0.15.0--0.16.0.sql: OK pgsql/share/semver/semver--0.2.4--0.3.0.sql: OK pgsql/share/semver/semver--0.31.0--0.31.1.sql: OK pgsql/share/semver/semver--0.11.0--0.12.0.sql: OK pgsql/share/semver/semver--0.5.0--0.10.0.sql: OK trunk.json: OK Done!

Most of the output here is verification:

Lines 3-32 verify each the checksums of each file in the package Line 33 verifies the version of the Trunk format Line 34 verifies Postgres version compatibility Line 35 verifies platform compatibility

And now, with all the verification complete, it installs the files. It does so by iterating over the subdirectories of the pgsql directory and installing them into the appropriate directory defined by pg_config. Two whit:

Line 36 installs files from pgsql/doc into pg_config --docdir Line 37 installs files from pgsql/pkglib into pg_config --pkglibdir Line 38 installs files from pgsql/share into pg_config --sharedir

And that’s it. Here’s where it put everything:

❯ (cd ~/.pgenv/pgsql-16.3 && find . -name '*semver*') ./lib/bitcode/src/semver ./lib/bitcode/src/semver/src/semver.bc ./lib/bitcode/src/semver.index.bc ./lib/semver.dylib ./share/extension/semver.control ./share/semver ./share/semver/semver--0.3.0--0.4.0.sql ./share/semver/semver--0.30.0--0.31.0.sql ./share/semver/semver--0.21.0--0.22.0.sql ./share/semver/semver--0.32.1.sql ./share/semver/semver--0.10.0--0.11.0.sql ./share/semver/semver--0.13.0--0.15.0.sql ./share/semver/semver--0.31.1--0.31.2.sql ./share/semver/semver--0.31.2--0.32.0.sql ./share/semver/semver--unpackaged--0.2.1.sql ./share/semver/semver--0.12.0--0.13.0.sql ./share/semver/semver--0.17.0--0.20.0.sql ./share/semver/semver--0.2.1--0.2.4.sql ./share/semver/semver--0.16.0--0.17.0.sql ./share/semver/semver--0.22.0--0.30.0.sql ./share/semver/semver--0.20.0--0.21.0.sql ./share/semver/semver--0.15.0--0.16.0.sql ./share/semver/semver--0.2.4--0.3.0.sql ./share/semver/semver--0.31.0--0.31.1.sql ./share/semver/semver--0.11.0--0.12.0.sql ./share/semver/semver--0.5.0--0.10.0.sql ./share/doc/semver ./share/doc/semver/semver.mmd

Looks like everything’s installed in the right place. Does it work?

Any PGXS project can try out the pattern; please do! Just download trunk.mk and install_trunk, import trunk.mk into your Makefile, install shasum, jq and rsync (if you don’t already have them) and give it a try.

The intent of this POC is to prove the pattern; this is not a complete or shippable solution. Following a comment period, I expect to build a proper command-line client (and SDK) to package up artifacts generated from a few build systems, including PGXS and pgrx.

Whether you try it out or not, I welcome a review of the proposal and your comments on it. I’d like to get this right, and have surely overlooked some details. Let’s get to the best binary packaging format we can.

I used the pgxn-tools image and started Postgres and installed the necessary tools with the command pg-start 16 rsync jq↩︎

The Pulse #97: Lone hacker takes down North Korea’s internet

Also: what NVIDIA becoming the world’s most valuable company says about AI, controversy at Slack and Adobe about terms and conditions in the GenAI era, and more

The Pulse is a weekly series covering insights, patterns, and trends within Big Tech and startups. Notice an interesting event or trend? Send me a message.

Today, we cover:

Industry pulse. Cuts at startups are finally trending downwards, social network, Microsoft Recall delayed infinitely, Adobe executives sued for deceptive pricing patterns, and more.

A lone hacker took down the internet in North Korea. How? A Florida-based cybersecurity entrepreneur was targeted by North Korean hackers, and decided to get his own back. With uncomplex denial-of-service attacks, he throttled internet access across all of North Korea for a week. This feat cost just $5,000, spent on virtual machines!

NVIDIA is the world’s most valuable company; what does it mean? NVIDIA has overtaken Microsoft as the world’s most valuable company, like router manufacturer Cisco did back in 2000 – also from Microsoft. Is this the peak of an “AI Boom,” like 2000 was the peak of the dotcom bubble?

Slack and Adobe controversy: update T&Cs for “GenAI.” Both companies suffered public backlashes and canceled subscriptions after users scrutinized outdated terms and conditions written before GenAI models existed. Adobe’s now updating its legally binding contract, and other companies will likely follow.

1. Industry pulse Fewer layoffs at startups, finally?

Unfortunately, news of startups slashing headcounts has been pretty constant since early 2022. But new data from equity platform Carta suggests this trend may finally be cooling.

Source: Peter Walker at Carta

It’s not just numbers of layoffs which are falling; more people are leaving jobs by choice, instead of being let go. Around 60% of workers in Carta’s figures left by choice, versus 40% being let go. A year ago the split was 50/50.

But Carta still finds that hiring is lagging, even though more recruitment is occuring than a few quarters ago. Peter Walker, who compiled this data, summarizes: “fewer layoffs is better than more layoffs — I'll take it.”

Chatkontrolle vertagt: Megaerfolg bei Verteidigung des digitalen Briefgeheimnisses!

Die EU-Regierungen werden sich heute nicht wie geplant für die Chatkontrolle aussprechen, die das Ende privater Nachrichten und sicherer Verschlüsselung eingeläutet hätte. Der belgische Ratsvorsitz nahm den Punkt kurzfristig von der Tagesordnung. Damit scheitert die Chatkontrolle zum wiederholten Male im Rat. Der Europaabgeordnete der Piratenpartei, digitale Freiheitskämpfer und Verhandlungsführer seiner Fraktion im Europäischen Parlament, Dr. Patrick Breyer, jubelt:

„Ohne das Engagement und den Protest von unzähligen Personen und Organisationen in Europa in den letzten Tagen hätten die EU-Regierungen heute totalitäre flächendeckende Chatkontrollen beschlossen, das digitale Briefgeheimnis und sichere Verschlüsselung beerdigt. Danke an alle, die Politikern geschrieben oder angerufen haben. Dass wir die orwellsche Chatkontrolle trotz des Umfallens Frankreichs erneut stoppen konnten, gehört gefeiert!

Die Überwachungsextremisten unter den EU-Regierungen und Big Sister Ylva Johansson sind damit gescheitert, eine qualifizierte Mehrheit herbeizutricksen. Wann lernen sie endlich vom EU-Parlament, dass wirksamer, gerichtsfester und mehrheitsfähiger Kinderschutz anders geht?

Jetzt muss die Bundesregierung endlich ihre Hausaufgaben machen und sich mit anderen kritischen Staaten auf gemeinsame Forderungen verständigen. Es reicht eben nicht, nur verschlüsselte Kommunikation ausnehmen zu wollen. Die verdachtslose, fehleranfällige Durchleuchtung privater Nachrichten ist der toxischste Teil des Verordnungsentwurfs, aber die Probleme gehen weit darüber hinaus. Wir brauchen deshalb einen neuen Ansatz, der auf vorbeugenden Kinderschutz statt Massenüberwachung und Bevormundung setzt! Der letzte ‚Kompromissvorschlag‘ der belgischen Ratspräsidentschaft muss in mindestens 4 Punkten grundlegend überarbeitet werden:

1. Keine verdachtslose Chatkontrolle: Anstelle flächendeckender Nachrichten- und Chatkontrolle soll die Justiz nur die Durchsuchung der Nachrichten und der Uploads von Verdächtigen anordnen können. Nur so kann vermieden werden, dass eine unverhältnismäßige Verordnung zur Massenüberwachung zwangsläufig vor Gericht scheitert und für Kinder überhaupt nichts erreicht wird.

2. Sichere Verschlüsselung schützen: Das sogenannte client-side scanning zur Unterwanderung sicherer Verschlüsselung muss ausdrücklich ausgeschlossen werden. Allgemeine Bekenntnisse zu Verschlüsselung im Gesetzestext sind nichts wert, wenn noch vor der Verschlüsselung durchleuchtet und ausgeleitet wird. Unsere persönlichen Geräte dürfen nicht zu Scannern pervertiert werden.

3. Anonymität schützen: Streichung verpflichtender Altersüberprüfungen durch alle Kommunikationsdienste, um das Recht auf anonyme Kommunikation zu retten. Whistleblower drohen zu verstummen, wenn sie vor Leaks dem Kommunikationsdienst gegenüber Ausweis oder Gesicht vorzeigen müssen.

4. Keine Appzensur für junge Menschen: Jugendliche zum Schutz vor Grooming ganz von Allerweltapps wie Whatsapp, Instagram oder Games ausschließen zu wollen, ist weltfremd und inakzeptabel. Stattdessen müssen die Voreinstellungen der Dienste datenschutzfreundlicher und sicherer werden.“

Hintergrund:

Nach dem neuesten Gesetzentwurf, der als „Uploadmoderation“ präsentiert wird, sollen Nutzer von Apps und Diensten mit Chatfunktionen gefragt werden, ob sie das verdachtslose und fehleranfällige Scannen und gegebenenfalls Ausleiten ihrer privat verschickten Bilder, Fotos und Videos akzeptieren. Mit „künstlicher Intelligenz“ sollen auch bisher unbekannte Bilder und Videos durchleuchtet werden. Lehnt ein Nutzer die Chatkontrolle ab, soll er gar keine Bilder, Fotos, Videos oder Links mehr verschicken oder empfangen können (Artikel 10). Trotz Lippenbekenntnissen für Verschlüsselung müssten Ende-zu-Ende-verschlüsselte Dienste die Chatkontrolle durch Einbau von Überwachungsfunktionen umsetzen, die „vor der Datenübertragung“ greifen sollen (sog. client-side scanning, Artikel 10a). Auf die Durchsuchung von Textnachrichten nach Hinweisen auf „Grooming“, die auch bisher kaum zum Einsatz kommt, soll genauso verzichtet werden wie auf das noch nie eingesetzte Scannen von Sprachkommunikation. Die Chats der Mitarbeiter von Sicherheitsbehörden und Militär sollten von der fehleranfälligen Chatkontrolle ausgenommen werden.

In einer Sitzung am 24. Mai machte der Juristische Dienst des Rates deutlich, dass eine verdachtslose massenhafte Chatkontrolle weiterhin vorgesehen sei und nach wie vor grundrechtswidrig bleibe.

Chatkontrolle: Politiker und Industrie schlagen Alarm wegen der beispiellosen Pläne der EU zur Messenger-Massenüberwachung

Morgen (Donnerstag) sollen die EU-Regierungen über einen Gesetzentwurf abstimmen (offiziell „Verordnung gegen sexuellen Missbrauch von Kindern“, aber bekannt als „Chatkontrolle“), der die automatisierte Durchsuchung und gegebenenfalls Ausleitung privater Chats vorsieht, darunter auch Ende-zu-Ende-verschlüsselte Chats, die verdächtige Fotos oder Videos enthalten sollen.[1] Lehnt ein Nutzer diese „Upload-Moderation“ seiner Chats ab, wird kann er keinerlei Bilder, Videos oder URLs mehr senden oder empfangen. 48 Abgeordnete aus Deutschland, Österreich, Luxemburg, der Tschechischen Republik und den Niederlanden haben einen Brief an ihre Regierungen veröffentlicht, in dem sie die Ablehnung der neuesten Version der Chatkontrolle fordern mit der Begründung, dass Massenüberwachung Grundrechte verletze und vor Gericht scheitern würde.[2] Signal und Threema haben angekündigt, dass sie ihre Dienste in der EU einstellen würden, wenn sie gezwungen würden, die vorgeschlagene automatisierte Überwachung (sogenanntes „Client-Side Scanning“) umzusetzen. Whatsapp-Chef Will Cathcart warnt: „Das Scannen von Nachrichten, wie es die EU vorschlägt, bricht die Verschlüsselung.“[3] Gestern Abend äußerte sich auch der NSA-Whistleblower Edward Snowden auf X und nannte den Vorschlag „eine erschreckende Massenüberwachungsmaßnahme“.[4]

Es ist noch nicht klar, ob die Befürworter genügend EU-Regierungen überzeugen können, um eine qualifizierte Mehrheit zu bilden, weshalb der Tagesordnungspunkt für morgen als „möglich“ gekennzeichnet ist.[1]

Vor diesem Hintergrund hat der Europaabgeordnete der Piratenpartei, Patrick Breyer, der die Position des Europaparlaments zu dem Vorschlag mitverhandelt hat[5], einen Aufruf an alle Bürger veröffentlicht, sich an die EU-Regierungen zu wenden. Breyer nennt die EU-Länder, deren Regierungen noch unentschlossen sein könnten.[6]

„Wenn die Chatkontrolle kommt, werden wir gängige sichere Messenger ganz einfach nicht mehr nutzen können – das bedeutet wir verlieren den Kontakt zu unseren Freunden und Kollegen in der ganzen Welt“, warnt Breyer. „Wollen wir wirklich, dass Europa weltweit führend beim Abhören unserer Smartphones und der flächendeckenden Überwachung der Chats von Millionen gesetzestreuer Bürger wird? Wir im Europäischen Parlament sind überzeugt, dass diese orwellsche Chatkontrolle das dringliche Anliegen eines besseren Kinder- und Opferschutzes verrät, weil sie unweigerlich vor Gericht scheitern wird. Wir fordern deshalb einen wirklich wirksamen Kinderschutz durch sicherere Apps, proaktive Säuberung des Internets und eine Pflicht zur Löschung illegaler Inhalte – nichts davon ist in dem dem belgischen Vorschlag vorgesehen, über den die Regierungen morgen abstimmen werden.“

Just a Theory

Compiling Postgres with LLVM

I decided to compile Postgres with LLVM this week but ran into failing tests due to server crashes. Here’s how to avoid the issue.

A quick post on the need to use a compatible Clang compiler when building Postgres with LLVM support. TL;DR: always point the CLANG variable to the correct Clang binary when compiling Postgres --with-llvm.

The Problem

I’m working on a POC for Postgres binary packaging (more on that soon) and wanted to try it with LLVM support, which generates JIT inline extensions. So I installed LLVM from Homebrew on my Mac and built a new Postgres --with-llvm and a pointer to llvm-config, as described in the docs:

brew install llvm ./configure \ --prefix=$HOME/pgsql-devel \ --with-llvm \ LLVM_CONFIG=/opt/homebrew/opt/llvm/bin/llvm-config make -j8 make install

No problems, excellent. Now let’s run the tests:

$ make check # output elided 1..222 # 37 of 222 tests failed. # The differences that caused some tests to fail can be viewed in the file "src/test/regress/regression.diffs". # A copy of the test summary that you see above is saved in the file "src/test/regress/regression.out". make[1]: *** [check] Error 1 make: *** [check] Error 2

This was a surprise! A quick look at that regression.diffs file shows:

+FATAL: fatal llvm error: Unsupported stack probing method +server closed the connection unexpectedly + This probably means the server terminated abnormally + before or while processing the request. +connection to server was lost

Yikes, the server is crashing! What’s in the log file, src/test/regress/log/postmaster.log? (Took a while to find it, thanks depesz!):

2024-06-18 14:13:52.369 EDT client backend[49721] pg_regress/boolean FATAL: fatal llvm error: Unsupported stack probing method

Same error. I tried with both the current master branch and the Postgres 16 release branch and got the same result. I pulled together what data I could and opened an LLVM issue.

The Solution

After a few hours, one of the maintainers got back to me:

The error message is LLVM reporting the backend can’t handle the particular form of “probe-stack” attribute in the input LLVM IR. So this is likely a bug in the way postgres is generating LLVM IR: please file a bug against Postgres. (Feel free to reopen if you have some reason to believe the issue is on the LLVM side.)

Okay so maybe it’s actually a Postgres bug? Seems odd, given the failures on both master and Postgres 16, but I wrote to pgsql-hackers about it, where Andres Freund quickly figured it out:

I suspect the issue might be that the version of clang and LLVM are diverging too far. Does it work if you pass CLANG=/opt/homebrew/opt/llvm/bin/clang to configure?

I gave it a try:

make clean ./configure \ --prefix=$HOME/pgsql-devel \ --with-llvm \ LLVM_CONFIG=/opt/homebrew/opt/llvm/bin/llvm-config \ CLANG=/opt/homebrew/opt/llvm/bin/clang make -j8 make install

And then make check:

$ make check # output elided 1..222 # All 222 tests passed.

Yay, that worked! So what happened? Well, take a look at this:

$ which clang /usr/bin/clang

That’s Clang as installed by the Xcode CLI tools. Apparently there can be incompatibilities between Clang and LLVM. So one has to be sure to use the Clang that’s compatible with LLVM. Conveniently, the Homebrew LLVM formula includes the proper Clang; all we have to do is tell the Postgres configure script where to find it.

Pity the Xcode CLI package doesn’t include LLVM; it would avoid the problem altogether.

Upshot

Always point the CLANG variable to the correct Clang binary when compiling Postgres --with-llvm. I’ve updated my pgenv configuration, which depends on some other [Homebrew]-installed libraries and plenv-installed Perl, to do the right thing on macOS:

PGENV_CONFIGURE_OPTIONS=( --with-perl "PERL=$HOME/.plenv/shims/perl" --with-libxml --with-uuid=e2fs --with-zlib --with-llvm LLVM_CONFIG=/opt/homebrew/opt/llvm/bin/llvm-config CLANG=/opt/homebrew/opt/llvm/bin/clang --with-bonjour --with-openssl # Replaced with --with-ssl=openssl in v14 --enable-tap-tests PKG_CONFIG_PATH=/opt/homebrew/opt/icu4c/lib/pkgconfig 'CPPFLAGS=-I/opt/homebrew/opt/readline/include -I/opt/homebrew/opt/openssl/include -I/opt/homebrew/opt/libxml2/include -I/opt/homebrew/opt/icu4c/include' 'CFLAGS=-I/opt/homebrew/opt/readline/include -I/opt/homebrew/opt/openssl/include -I/opt/homebrew/opt/libxml2/include -I/opt/homebrew/opt/icu4c/include' 'LDFLAGS=-L/opt/homebrew/opt/readline/lib -L/opt/homebrew/opt/openssl/lib -L/opt/homebrew/opt/libxml2/lib -L/opt/homebrew/opt/icu4c/lib' )

And now perhaps this post has helped you fix the same problem.

🏔 Extension Ecosystem Summit 2024

A brief report on the PostgreSQL Extension Ecosystem Summit at PGConf.dev 2024 in Vancouver, Canada.

The PostgreSQL Extension Ecosystem Summit took place at PGConf.dev in Vancouver on May 28, 2024 and it was great! Around 35 extension developers, users, and fans gathered for an open-space technology (OST)-style unconference. I opened with a brief presentation (slides) to introduce the Summit Theme:

Extension issues, designs and features Development, packaging, installation, discovery, docs, etc. Simplify finding, understanding, and installing Towards ideal ecosystem of the future For authors, packagers, DBAs, and users Lots of problems, challenges, decisions Which do you care about? Collaborate, discover, discuss, document Find answers, make decisions, set directions Inform the PGXN v2 project

Before the Summit my co-organizers and I had put up large sticky notes with potential topics, and after reviewing the four principles and one law of [OST], we collectively looked them over and various people offered to lead discussions. Others volunteered to take notes and later published them on the community wiki. Here’s our report.

Extension Metadata

Samay Sharma of Tembo took point on this discussion, while David Wagoner of EDB took notes. The wide-ranging discussion among the five participants covered taxonomies, versioning, system dependencies, packaging & discoverability, development & compatibility, and more.

The discoverability topic particularly engaged the participants, as they brainstormed features such as user comments & ratings, usage insights, and test reporting. They settled on the idea of two types of metadata: developer-provided metadata such as external dependencies (software packages, other extensions the extension depends on etc.) and user metadata such as ratings. I’m gratified how closely this hews to the metadata sketch’s proposed packaging (author) and registry (third party) metadata.

Binary Distribution Format

I led this session, while Andreas “ads” Scherbaum took notes. I proposed to my four colleagues an idea I’d been mulling for a couple months for an extension binary distribution format inspired by Python wheel. It simply includes pre-compiled files in subdirectories named for each pg_config directory config. The other half of the idea, inspired by an Álvaro Hernández blog post, is to distribute these packages via OCI — in other words, just like Docker images. The participants agreed it was an interesting idea to investigate.

We spent much of the rest of the time reviewing and trying to understand the inherent difficulty of upgrading binary extensions: there’s a period between when an extension package is upgraded (from Yum, Apt, etc.) and ALTER EXTENSION UPDATE updates it in the database. If the new binary doesn’t work with old versions, it will break (and potentially crash Postgres!) until they update. This can be difficult in, say, a data analytics environment with uses of the extension in multiple databases and functions, and users may not have the bandwidth to ALTER EXTENSION UPDATE any code that depends on the extension.

This issue is best solved by defensive coding of the C library to keep it working for new and old versions of an extension, but this complicates maintenance.

Other topics included the lack of support for multiple versions of extensions at one time (which could solve the upgrade problem), and determining the upgrade/downgrade order of versions, because the Postgres core enforces no version standard.

ABI/API discussion

Yurii Rashkovskii took point on this session while David Christensen took notes. Around 25 attendees participated. The discussion focused in issues of API and ABI compatibility in the Postgres core. Today virtually the entire code base is open for use by extension developers — anything in header files. Some recent research revealed a few potentially-incompatible changes in minor releases of Postgres, leading some to conclude that extensions must be compiled and distributed separately for every minor release. The group brainstormed improvements for this situation. Ideas included:

Spelunking the source to document and categorize APIs for extensions Documenting color-coded safety classifications for APIs: green, yellow, or red Designing and providing a better way to register and call hooks (observability, administration, isolation, etc.), rather than the simple functions Postgres offers today Developing a test farm to regularly build and tests extensions, especially ahead of a core release And of course creating more hooks, such as custom relation type handling, per-database background workers, a generic node visitor pattern, and better dependency handling Including/Excluding Extensions in Core

Keith Fiske led the discussion and took notes for this session, along with 10-15 or so attendees. It joined two topics: When should an extension be brought into core and when should a contrib extension be removed from core. The central point was the adoption of new features in core that replace the functionality of and therefore reduce the need for some extensions.

Replacing an extension with core functionality simplifies things for users. However, the existence of an extension might prevent core from ever adding its features. Extensions can undergo faster, independent development cycles without burdening the committers with more code to maintain. This independence encourages more people to develop extensions, and potentially compels core to better support extensions overall (e.g., through better APIs/ABIs).

Contrib extensions currently serve, in part, to ensure that the extension infrastructure itself is regularly tested. Replacing them with core features would reduce the test coverage, although one participant proposed a patch to add such tests to core itself, rather than as part of contrib extensions.

The participants collaborated on a list of contrib extensions to consider merging into core:

amcheck pageinspect pg_buffercache pg_freespacemap pg_visibility pg_walinspect pgstattuple

They also suggested moving extension metadata (SQL scripts and control files) from disk to catalogs and adding support for installing and using multiple versions of an extension at one time (complicated by shared libraries), perhaps by the adoption of more explicit extension namespacing.

Potential core changes for extensions, namespaces, etc.

Yurii Rashkovskii and David Christensen teamed up on this session, as well (notes). 15-20 attendees brainstormed core changes to improve extension development and management. These included:

File organization/layout, such as putting all the files for an extension in a single directory and moving some files to the system catalog. Provide a registry of “safe” extensions that can be installed without a superuser. Adding a GUC to configure a second directory for extensions, to enable immutable Postgres images (e.g., Docker, Postgres.app). The attendees consider this a short term fix, but still useful. (Related: I started a pgsql-hackers thread in April for a patch to to just this). The ability to support multiple versions of an extension at once, via namespacing, came up in this session, as well. Participants also expressed a desire to support duplicate names through deeper namespacing. Fundamentally, the problem of namespace collision redounds to issues un-relocatable extensions. Until Next Time

I found it interesting how many topics cropped up multiple times in separate sessions. By my reading most cited topics were:

The need to install and use multiple versions of an extension A desire for deeper namespacing, in part to allow for multiple versions of an extension A pretty strong desire for an ABI compatibility policy and clearer understanding of extension-friendly APIs

I expect to put some time into these topics; indeed, I’ve already started a Hackers thread proposing an ABI policy.

I greatly enjoyed the discussions and attention given to a variety of extension-related topics at the Summit. So much enthusiasm and intelligence in one places just makes my day!

I’m thinking maybe we should plan to do it again next year. What do you think? Join the #extensions channel on the Postgres Slack with your ideas!

‘The Mythical Man-Month’ by Frederick P. Brooks was published in 1975 – almost 50 years ago; and the book still bears an influence: tech professionals quote it today, like “Brooks’ Law;” the observation that adding manpower to a late software project makes it more late.

When Brooks wrote Mythical Man-Month, he was project manager of the IBM System/360 operating system, one of the most complex software projects in the world at the time. The book collates his experience of building large and complex software during the 1970s, and some best practices which worked well.

I’ve been working through this book written near the dawn of software to see which predictions it gets right or wrong, what’s different about engineering today – and what stays the same. In Part 1 of this series, we covered chapter 1-3, and chapters 4-7 in Part 2. Today, it’s chapters 8, 9, and 11, covering:

Estimations. Fifty years later, it still takes around twice as long to get work done as originally estimated, unless distractions are part of the estimate.

Developer productivity. High-level languages provide definite productivity boosts, and developers easily write 10x more lines per code than 50 years ago.

The vanishing art of program size optimization. Program size and memory usage were critical characteristics of programs in the 70s – and developers did creative workarounds, sometimes making trade-offs on performance. Today, most devs don’t have to care about this metric, although a handful of areas still optimize for size.

Prototyping. Brook argues the first version of a program needs to be thrown away. Until very recently shipping a prototype (aka MVP) to production was common, but is it bad for business in 2024?

Back to the ‘70s? Shipping polished software, not MVPs. Interestingly, we could be seeing a return to the shipping approach which Brooks advocated 50 years ago.

1. Estimation

Chapter 8 is “Calling the shot,” about working out how long a piece of software takes to build. It’s always tempting to estimate how long the coding part of the work should take, multiply that by a number (like 2 or 3), and get the roughly correct estimate. However, Brooks argues this approach doesn’t work, based on his observation of how developers spent time in the ‘1970s. He said it was more like this:

“For some years, I have been successfully using the following rule of thumb for scheduling a software task:

⅓ planning

⅙ coding

¼ component test and early system test

¼ system test, all components in hand.”

Assuming this is the case, should one not “just” multiply the coding estimate by six? No! Errors in the coding estimate lead to absurd estimates, and it assumes you can estimate the coding effort upfront, which is rare. Instead, Brooks shares an interesting anecdote:

“Each job takes about twice as long as estimated.” This is an anecdote shared with Brooks by Charles Portman, manager of a software division in Manchester, UK. Like today, delays come from meetings, higher-priority but unrelated work, paperwork, time off for illness, machine downtime, etc. Estimates don’t take these factors into account, making them overly optimistic in how much time a programmer really has.

This all mostly holds true today; specifically that it still takes about twice as long to complete something as estimated, at least at larger companies. The rule of thumb to multiply estimates by two, to account for meetings, new priorities, holidays/sickness, etc, is still relevant. The only factor Brooks mentions in his 1975 book that’s no longer an issue is machine availability.

2. Developer productivity

Brooks then moves to the question of how many instructions/words it’s reasonable to expect a programmer to produce, annually. This exploration becomes a bid to quantify developer productivity by instructions typed, or lines of code produced.

Developer productivity in the 1970s

Like many managers and founders today, Brooks wanted to get a sense of how productive software developers are. He found pieces of data from four different studies, and concluded that average developer output in the 1970s was:

600-5,000 program words per year, per programmer. Brooks collected data from four data sources on programming productivity.

High-level languages make developers much more productive. Brooks cites a report from Corbató of MIT’s Project MAC reports, concluding:

“Programming productivity may be increased by as much as five times when a suitable high-level language is used.”

Brooks also shared another interesting observation:

“Normal” programs > compilers > operating systems for effort. Brooks noticed that compiler and operating systems programmers produce far fewer “words per year” than those building applications (called “batch application programs.”) His take:

“My guideline in the morass of estimating complexity is that compilers are three times as bad as normal batch application programs, and operating systems are three times as bad as compilers.”

Developer productivity today

So, how has developer productivity changed in 50 years?

Today, we’re more certain that high-level programming languages are a productivity boost. Most languages we use these days are high-level, like Java, Go, Ruby, C#, Python, PHP, Javascript, Typescript, and other object-oriented, memory-safe languages. Low-level languages like C, C++ and Assembly, are used in areas where high performance is critical, like games, low-latency use cases, hardware programming, and more niche use cases. The fact that we use high-level languages is testament to their productivity boosts. 

Studies in the years since have confirmed the productivity gains Brooks observed. A paper entitled Do programming languages affect productivity? A case study using data from open source projects investigated it:

“Brooks is generally credited with the assertion that annual lines-of-code programmer productivity is constant, independent of programming language. [...] Brooks states, “Productivity seems constant in terms of elementary statements, a conclusion that is reasonable in terms of the thought a statement requires and the errors it may include.” [1] (p. 94) 

This statement, as well as the works it cites, however, appears to be based primarily on anecdotal evidence. We test this assertion across ten programming languages using data from open source software projects.”

The study looked at nearly 10,000 open source projects, the number of lines developers committed, and whether the language was high-level or low-level. They found that high-level languages resulted in more lines of code committed per developer. Assuming that lines of code correlate with productivity, it means high-level languages are more productive.

But we know lines of code are not particularly telling in themselves. However, if you’ve worked with low and high-level languages, you’ll know high-level languages are easier to read and write, and they offer an additional layer of abstraction for things like memory management, hardware interaction, and error handling. They require less onboarding and expertise to write, and are generally harder to make errors with. So it’s little surprise that unless there’s a strong reason to go low-level, most developers choose high-level languages.

It’s interesting that languages offering the performance benefits of low-level languages with the clean syntax of high-level languages seem to be getting more popular; a good example of which is Rust.

OS or kernel development is still much slower than application development today. Brooks’ observation that operating system and compiler developers made far fewer code changes annually than application developers – despite also working fulltime as programmers – also remains true.

The more critical or widely-used a system is, the more care is needed when making changes. The Linux kernel illustrates just how small many changes are; many are only a few lines: here’s a 4-line change to switch to new Intel CPU model defines, or a five-line change fixing a threading bug:

A few lines of code changes to fix a kernel memory corruption issue in the Linux kernel. Full pull request

It’s worth noting there are often no unit tests or other forms of automated tests in key systems like operating system kernels, due to the low-level software. This means changes to the kernel take much more time and effort to verify. Behind every line change, there’s almost always more deliberation, experimentation, and thought.

Lines of code output-per-developer definitely feels like it has increased since the 1970s. It’s amusing to read that the average programmer wrote around 40-400 “instructions” per month, back then. Of course, it’s worth keeping in mind that most of the code was in lower level languages, and some of it applied to operating systems’ development.

Checking GitHub data for some more popular open source projects, I found:

Kubernetes: on average, 1,300 lines added or deleted per contributor the last month

Sourcegraph: 730 lines changed per contributor in the last month

Bluesky: 3,500 lines changed per contributor in the last month

Amazon: 5,600 lines changed per month based on one example. Software engineer turned engineering manager Andrew Luly shared that he added and removed 750,000 lines of code during 11 years at the company. Dividing that by the number of months gives the monthly average.

These figures suggest it’s fair to say developers today produce more code. My sense is that this change is due to using higher-level languages, modern tools like automated testing (tests also count as lines of code,) and more safety nets being in place that enable faster iteration.

Of course, coupling business value to lines of code remains largely futile. We’re seeing developers being able to “output” and interpret more lines of code than before, but it’s pretty clear that there’s a limit on how much code is too much. This is why mid-size and larger companies push for small pull requests that are easier to review, and make potential bugs or issues easier to catch.

We know far more about developer productivity these days, but haven’t cracked accurate measurement. The best data point Brooks could get his hands on for developer productivity was lines of code and numbers of words typed by a programmer. We know that looking at only this data point is useless, as it’s possible for developers to generate unlimited quantities of code while providing zero business value. Also, generating large amounts of code is today even easier with AI coding tools, making this data point still more irrelevant.

This publication has explored the slippery topic of developer productivity from several angles:

A new way to measure developer productivity – from the creators of DORA and SPACE. An exclusive interview with four researchers behind a new developer productivity framework called The three dimensions of DevEx.

Measuring developer productivity? A response to McKinsey. The consultancy giant devised a methodology it says can measure software developer productivity. But that measurement comes at a high price, and we offered a more sensible approach. Part 2 was also published in collaboration with well-known software engineer and author Kent Beck, who recently published his latest book, Tidy First.

Measuring developer productivity: real-world examples. A deep dive into the developer productivity metrics used by Google, LinkedIn, Peloton, Amplitude, Intercom, Notion, Postman, and 10 other tech companies.

The Full Circle of Developer Productivity with Steve Yegge. Steve shares that in the 1990s he experienced incredible developer productivity at GeoWorks, thanks to specialized debugging tooling which that company built. He’s now back building similar tools at Sourcegraph where he was Head of Engineering, before working again as a hands-on software engineer.

Measuring Engineering Efficiency at LinkedIn. Learnings and insights from a principal engineer at LinkedIn and veteran of developer tools and productivity, Max Kanat-Alexander.

How Uber is measuring engineering productivity. Inside Uber’s launch of its Eng Dashboard. How do engineers and managers feel about this tool, and which metrics does it track?

Measuring software engineering productivity. How to measure developer productivity, how are DORA and SPACE related, and some hard-earned lessons, with Laura Tacho.

Ever more data suggests that to measure developer productivity, several metrics in combination are needed; including qualitative ones, not only quantitative metrics that are easily translatable into figures. Qualitative metrics include asking developers how productive they feel, and what slows them down.

Building a productive software engineering team is tricky; it takes competent software engineers, hands-on (or at least technical-enough) managers, a culture that’s about more than firefighting, and adjusting approaches to the needs of the business and teams. After all, there’s little point in having an incredibly productive engineering team at a startup with no viable business model. No amount of excellent software will solve this core problem!

We previously covered how to stay technical as an engineering manager or tech lead, and also how to stay hands-on.

Abgeordnete in der gesamten EU fordern den EU-Rat auf, den Vorschlag zur Chatkontrolle abzulehnen

Der folgende Brief von Abgeordneten aus verschiedenen Parlamenten in der Europäischen Union wurde heute versendet (und ist weiter für Unterschriften offen). In diesem Beitrag ist eine deutsche Übersetzung des Briefs, hier ein Link zur englischen Originalfassung.

Sehr geehrter Rat der Europäischen Union,

Sehr geehrte nationale Regierungen,

in den letzten Tagen der belgischen EU-Ratspräsidentschaft hat Belgien seine letzte Initiative vorgelegt, um im Rat der EU eine allgemeine Ausrichtung zur stark umstrittenen CSA-Verordnung (Vorschlag für eine Verordnung des Europäischen Parlaments und des Rates mit Vorschriften zur Verhütung und Bekämpfung des sexuellen Missbrauchs von Kindern) zu erreichen. Mit der möglichen Abstimmung über die CSA-Verordnung am 19. Juni riskiert der Rat weit mehr als nur die Verabschiedung einer einfachen Verordnung.

Sexueller Missbrauch und die Ausbeutung von Kindern, einschließlich der Verbreitung von Material über den sexuellen Missbrauch von Kindern, müssen mit äußerster Entschlossenheit im Einklang mit der Rechtsstaatlichkeit bekämpft werden. Der von der EU-Kommission vorgelegte Verordnungsvorschlag enthält zwar einige gute und wichtige Maßnahmen, wie z.B. das EU-Zentrum, aber es ist höchst fraglich, ob zentrale Aspekte der Verordnung mit den europäischen Grundrechten vereinbar sind.

Als Parlamentarier beobachten wir mit großer Sorge den Vorschlag des EU-Rates, der die Vertraulichkeit privater Kommunikation aushebeln würde. Auch wenn die belgische Ratspräsidentschaft nun einen Kompromissvorschlag vorgelegt hat, der die Verpflichtung zum Scannen privater unverschlüsselter sowie verschlüsselter Video- und Bildinhalte einschränkt, bleibt er ein Eingriff in die digitalen Grundrechte und führt die Diskussion zurück an den Ursprung der Debatte. Tatsächlich entspricht der belgische Vorschlag den ersten Pläne der Kommission, die im Dezember 2021 bekannt wurden.

Sichere und verschlüsselte Kommunikation ist für jeden Menschen von größter Bedeutung. Dies gilt auch für Kinder und Opfer von sexuellem Missbrauch, um sichere Rettungs- und Hilfeleistungen zu ermöglichen – insbesondere in Ländern, in denen sich Opferhilfsorganisationen nicht auf die Unterstützung und das Stillschweigen der staatlichen Strafverfolgungsbehörden verlassen können.

Abgesehen von der Gefahr, dass der Eingriff in die digitale Selbstbestimmung der Menschen dem Ziel des CSA-Vorschlags zuwiderläuft, könnte es zu mehreren unbeabsichtigten, aber gefährlichen Nebeneffekten kommen:

Client Side Scanning (CSS) und jede andere Massenüberwachung würde die Übermittlung vertraulicher Informationen unmöglich machen: Das Scannen würde Nutzer betreffen, die auf vertrauliche Kommunikation angewiesen sind und deren Kommunikation einen besonderen Anspruch auf Schutz hat (zur Vertraulichkeit verpflichtete Berufsgruppen wie Journalisten, Rechtsanwälte, der medizinische Bereich, aber auch Whistleblower). Außerdem könnten eingebaute Hintertüren die Vertraulichkeit digital übermittelter Betriebsgeheimnisse und Geschäftsvorgänge gefährden. Verschlüsselung schützt die Identität und den Inhalt der Kommunikationsteilnehmer und wahrt so die Autonomie der Opfer sexueller Gewalt. Eine demokratische Gesellschaft und demokratische Debatten brauchen vertrauliche Schutzräume: Demokratische Gesellschaften brauchen Privatsphäre zur Meinungs- und Willensbildung. Die vorgeschlagenen Maßnahmen bergen die Gefahr, zu einer Selbstzensur zu führen und sichere Räume für Kinder und Opfer sexueller Gewalt, aber auch für alle anderen zu gefährden. Außerdem werden sie wahrscheinlich dazu führen, dass Nutzer digitale Dienste nicht mehr nutzen wollen und das Vertrauen in die Anbieter verlieren, wenn ihre Daten nicht sicher und geschützt sind. Blaupause für autoritäre Staaten und Schwächung der Cybersicherheit: Durch den Aufbau einer Architektur, die jede Möglichkeit der privaten digitalen Kommunikation untergräbt, könnte die Verordnung unbeabsichtigt als Blaupause für die Überwachung in autoritären Staaten dienen und als eingebaute Hintertür dienen, die leicht für alle Arten von Überwachungspraktiken (z. B. Geschäftsgeheimnisse) und Cyberkriminelle ausgenutzt werden kann. Einmal aufgebaut, ist diese IT-Architektur eine Einladung zur Aushöhlung der Privatsphäre. Beeinträchtigung von digitalen Bildungs-, Jugend- und Hilfsdiensten: Die in einigen europäischen Ländern übliche Praxis, wichtige Informationen zur sexuellen Gesundheit an solche Bildungseinrichtungen weiterzugeben, wird dadurch abgeschafft.

Die verpflichtende Überwachung privater Nachrichten ohne Verdacht birgt die Gefahr, ein Klima des Generalverdachts zu schaffen. Ein solcher Ansatz wird dem Bild der Europäischen Union als Garant der Freiheit irreparablen Schaden zufügen.

Wir warnen ausdrücklich davor, dass die Verpflichtung zum systematischen Scannen verschlüsselter Kommunikation, ob nun “Upload-Moderation” oder “Client-Side-Scanning” genannt, nicht nur die sichere Ende-zu-Ende-Verschlüsselung brechen würde, sondern mit hoher Wahrscheinlichkeit auch der Rechtsprechung des Europäischen Gerichtshofs nicht standhalten wird. Vielmehr stünde ein solcher Angriff in völligem Gegensatz zum europäischen Engagement für sichere Kommunikation und digitale Privatsphäre sowie für die Menschenrechte im digitalen Raum.

Wir brauchen daher dringend einen Ansatz, der dem Schutz und der Prävention von sexuellem Kindesmissbrauch Vorrang einräumt, mehr Ressourcen und eine gezieltere Koordinierung der europäischen Strafverfolgungsbehörden vorsieht, die Unterstützung der Opfer im Einklang mit den Grundrechten stärkt und es vermeidet, sich auf ein falsches Gefühl der Sicherheit durch Technosolutionismus zu verlassen.

Als nationale und europäische Parlamentarier sind wir überzeugt, dass die vorgeschlagenen Maßnahmen nicht mit den europäischen Grundrechten vereinbar sind. Wir setzen uns für die Wahrung des Rechts auf anonyme und pseudonyme Nutzung des Internets sowie für die Stärkung der Ende-zu-Ende-Verschlüsselung ein.

Wir fordern alle verhandelnden Regierungen im Ausschuss der Ständigen Vertreter (COREPER / AStV) dringend auf, eine allgemeine Ausrichtung auf der Grundlage des von Belgien vorgelegten Kompromissvorschlags abzulehnen.

Just a Theory

POSETTE 2024

I attended and gave a presentation at POSETTE, an event for Postgres. This post highlights some talks and the slides for my own.

Last week, I attended and presented at POSETTE, An Event for Postgres. A selection of the presentations I found worthy of attention.

Good Talks

Comparing Postgres connection pooler support for prepared statements by Jelte Fennema-Nio. Jelte did a great job outlining the challenges he encountered adding protocol-level prepared query support to PgBouncer. So many edge cases! Very much a worthwhile effort, and an important contribution. In the Discord “hallway track”, Jelte said he has some ideas how to add support for LISTEN/NOTIFY, which also requires connection affinity. Alas, there’s no protocol-level support, so it’ll be tricky. I suspect I’ll eventually move the PGXN Bot to something like pgmq to avoid the issue.

How to work with other people by Jimmy Angelakos and Floor Drees. Jimmy & Floor capably highlighted issues of neurodiversity and mental health in the Postgres community and the workplace. I greatly appreciate the increasing awareness of and discussions about these issues, which for far to long have remained hidden or misunderstood. All too often they still are. The more people talk about them, the more they’ll be accepted and the better things will become. Love seeing this.

Even JSONB In Postgres Needs Schemas by Chris Ellis. Chris concisely introduced the concept of JSON validation via check constraints to ensure the integrity of data. He started with simple validation with json_typeof(), moved to more comprehensive validation of various parts of a JSON or JSONB object, and ultimately full JSON Schema validation with the pg_jsonschema extension. Having recently written my own JSON Schema extension, I was happy to see this topic receive more attention. The tool Chris developed to convert JSON schema to a SQL function seems super neat, too — a great way to bootstrap a check constraint from a JSON Schema where no such extension exists, such as the big cloud providers.

I Also Spoke

I also gave a talk, State of the Postgres Extension Ecosystem, expanding upon my mini-Summit session. I think it came out pretty well, and hope it helps to get more people interested in extensions and solve the challenges for finding, evaluating, installing, and using them everywhere. Links:

Video PDF PDF with Notes Keynote Next Year

I found POSETTE a very nice Postgres conference. I applaud its commitment to a fully-virtual venue. In-person get-togethers are great, but not everyone can travel to them for reasons of cost, time, family, health, and more. Better still, the speakers recorded their presentations in advance, allows us to fully participate in discussion during our talks! (I mostly used my time to offer corrections and links to relevant resources.)

For those interested in Postgres, I heartily endorse this free, fully remote conference. Perhaps I’ll “see” you there next year.

Die Piratenpartei warnt vor der kommenden Abstimmung über die Chatkontrolle im Europaparlament. Seit mehreren Monaten warnt die Partei zusammen mit ihrem Europaabgeordneten Dr. Patrick Breyer vor dem Ende des Briefgeheimnisses im Netz. Gestern berichtete der SPIEGEL, dass das Bundeskriminalamt mehr als die Hälfte der Chats, Fotos und Videos, die freiwillig von US-Diensten geleakt wurden, im Jahr 2023 als “nicht strafrechtlich relevant” eingestuft wurden – so viele wie nie zuvor.[1] Heute wurde von POLITICO der finale Gesetzestext geleakt, der bisher sicher Ende-zu-Ende-verschlüsselte Apps wie Whatsapp oder Signal weltweit erstmals zum Einbau einer Überwachungsfunktionen zwingen würde.[2] Signal hat angekündigt, seine Dienste eher in der EU einzustellen als die verlangten Überwachungsfunktionen einzubauen. Das in der Schweiz ansässige Unternehmen Threema meldete heute, ebenfalls von der Chatkontrolle betroffen zu sein. Es werde nötigenfalls “andere Kommunikationsdienste aufrufen, die EU mit uns zu verlassen.”[3]

Die PIRATEN rufen dazu auf, kurz vor der Abstimmung noch einmal laut zu werden und gegen die Chatkontrolle zu protestieren.[4]

„Dass eine Technologie wie die Chatkontrolle Unschuldige treffen wird, ist kein hypothetisches Szenario, sondern Realität“, so Lukas Küffner, Vorsitzender der Piratenpartei. „Noch ist jedoch nichts entschieden. Es liegt an jedem Einzelnen, Einfluss auf die Abgeordneten im EU-Parlament zu nehmen. Wir brauchen Proteste, online und offline. Ist die Chatkontrolle erst einmal besiegelt, birgt sie unkontrollierbares Missbrauchspotential.“

Der EU-Abgeordnete Dr. Patrick Breyer kommentiert: “Wir stehen am Rande eines so extremen Überwachungsregimes, wie es nirgendwo sonst in der freien Welt existiert. Nicht einmal Russland und China haben es geschafft, Wanzen in unsere Smartphones einbauen zu lassen, wie es die EU beabsichtigt. Um Kritiker innerhalb der französischen Regierung zum Schweigen zu bringen und die Öffentlichkeit zu täuschen, enthält der endgültige Gesetzestext Lippenbekenntnisse zu sicherer Verschlüsselung, während er sie in Wirklichkeit zerstört, wie Hunderte von Wissenschaftlern deutlich gemacht haben. Die EU-Regierungen verstehen das sehr gut, wie die Ausnahme in Artikel 7 für ‘Nutzerkonten, die vom Staat für Zwecke der nationalen Sicherheit, der Aufrechterhaltung von Recht und Ordnung oder für militärische Zwecke verwendet werden’ zeigt. Ob verschlüsselt oder nicht: Wahllose Durchsuchungen und fehleranfällige Leaks privater Chats und intimer Fotos zerstören unser digitales Briefgeheimnis. Wenn die Chatkontrolle durchkommt, wird sie der ständigen Überwachung unserer privaten Chats für jedgliche Zwecke Tür und Tor öffnen, wie es Europol bereits gefordert hat. Der Logik der Chatkontrolle folgend wäre das verdachtslose Öffnen und Scannen aller unserer Briefe der nächste Schritt.”

Im Vorfeld der Abstimmung am Mittwoch trifft sich morgen eine Arbeitsgruppe zu einer “Fragen und Antworten”-Sitzung zu dem Vorschlag[5].

Anlaufstellen, um den eigenen Protest zu äußern, sind die Ständigen Vertretungen der Regierung in der Europäischen Union sowie alle Social Media-Kanäle.

Ergänzung: Die Abstimmung soll jetzt am Donnerstag stattfinden.[6]
