How? Have you tried contributing a reasonable implementation with test coverage and it was rejected?

> changes are aggregated and committed back to S3 roughly every 60 seconds as a single PUT
Single PUT per file I assume?

Upgraded to one of the latest iPhone recently. First time I clicked on “transfer data from old phone”. I’m used to reinstalling the operating system every couple of months from when I used Windows. It took maybe 15 minutes with close to 0 interactions. Everything was transferred. I was already authenticated in apps. What took manual steps was eSIM transfers.
I don’t remember exact steps so there could have been a bit more. But it was an impressive experience and I told my geek friends about it. They were surprised this is the first time I used this feature.

Wrap gdb in a shell script and you’ve got yourself an actual profiler: https://poormansprofiler.org/

I love P and have used it for personal projects (like OSWALD^1) and at work (for some Redpanda components).
I find it very approachable. If you know some basic theory of distributed systems and have been exposed to actors and state machines before, you should be able to have some non trivial models in a few days at days.
Things get slightly more complicated when you begin to ask yourself whether or not you have validated enough of the state space to have confidence in the design. The verifier has a much of options who care poorly documented.
Recently, P was extended to support exploring the entire state space (PEX mode) as well as a prover. These have only rudimentary documentation. I learned about them more by looking at code.

According to public information, AWS uses both and not only. AWS wrote a paper on the topic with some details about their applications of
formal methods^1. AWS is a large org though, it would be hard to generalise or reduce their approach to any single method.

Later add: I believe P creator is employed by AWS at this moment.

Love that it makes you spell the mangled symbols. Forces the brain to do some proper work.

I do often ask Claude Code or Gemini CLI to write commits. I agree with you on why being important. Majority of these being bug fixes accompanied tests where the why is easily inferred from the change/newly added tests and their comments.

*Engines That Move Markets: Technology Investing from Railroads to the Internet and Beyond* by Alasdair G. M. Nairn
I’ve had a few aha moments while reading this book. Although it's primarily written from an investor's perspective, it does contain a fair share of insight about creation and commercialisation of technology, the mechanics of monopolies, government involvement, foreign affairs, etc.

How does something like this scale for more than 10 people? 100? 1000?

While I was writing a tool for myself to summarise daily the top N posts from HN, Google Trends, and RSS feed subscriptions I had the same problem.
The quick solution was to use beautiful soup and readability-lxml to try and get the main article contents and then send it to an LLM.
The results are ok when the markup is semantic. Often it is not. Then you have tables, images, weirdly positioned footnotes, etc.
I believe the best way to extract information the way it was intended to be presented is to screenshot the page and send it to a multimodal LLM for “interpretation”. Anyone experimented with that approach?

The aspiration goal for the tool is to be the Presidential Daily Brief but for everyone.
