   Last Sunday we discussed that we all learn anew, how to deal with agentic SDLC. Here's a great interview with a principal engineer at Adyen and a former Amazonian Heitor Lessa on how he approaches this. The interview is long and information-dense at times, but it's worth the time! #ai #youtube

   The Hidden Cost of Postgres Constraints at Scale is a description of a bottleneck foreign keys can create in a write-heavy PostgreSQL table. It also has recommendations of what you can do to overcome that. Now, I would say, it's a corner case for many people. The author works in a company that develops their own time series solution based on Postgres, so for them, it makes sense. For the vast majority of people, I would argue, it makes more sense to offload the integrity checks to the database…

   A postmortem for the recent GitHub incident. Regarding the cause: The immediate cause of the failure was network saturation on load balancers in Central US due to a new peak in traffic. Originally this was caused by an Istio sidecar pod reaching its concurrency limits and failing to auto scale correctly because of a misconfigured policy that watched host service but not sidecar limits. One failure cascaded to more and eventually four HAProxy nodes exhausted their flow limits, degrading the gate…

   ​University of Colorado published an article about a study of 7700 employees that shows that Remote workers report the highest well-being. The study simply analyzed the self-reported data without any judgments on why exactly this is the case, but one of the authors points out that: The study did not explore why remote workers reported higher well-being, but Johnson points to a growing body of research on autonomy and flexibility. One explanation is that remote workers have greater control ove…

   ​​Happy Independence Day of Ukraine! 💛💙 It always starts with small steps, but every step counts. So today, I'd like to get back to small fundraisers that also matter! Here, a friend of mine is raising funds for a pickup track for the Zaporizhzhia direction. You can find more info in this Instagram post (in Ukrainian). You can donate to this Monobank jar: https://send.monobank.ua/jar/8Mjotj4Uei #donations #Ukraine

   A great article about Postgres' MVCC, or rather, issues with MVCC and the ways other engines tried to mitigate those. It has a neat comparison of the tradeoffs, strong and weak parts of different implementations. It also provides insights into how different DB engines work. A quote: ... if someone tells you a database has solved multi-versioning, ask them the four questions: where do old versions live, which way do chains point, what do indexes point at, and who cleans up. Then ask what happe…

   Cloudflare shares a story of how they automated GitHub issues triage with AI for their Astro project. It neatly shows the evolution from a collection of skills to a semi(?) autonomous state machine that has taken the project to zero open issues. They also share the workflows they use publicly, but in my opinion the more valuable lesson here is the step-by-step model of how they got there. #ai #open_source

   I've written an article about load testing of Apollo Router - a GraphQL API gateway. It's mostly pictures, so it should be easy to follow :) #graphql #load_test

    ​​For today's Donations Monday, I'd like to remind you about a fundraiser by a friend of mine. Its goal is to get 70k UAH for a pick up truck. So far, about 20k has been raised. Let's make it happen! https://send.monobank.ua/jar/8Mjotj4Uei #donations #Ukraine

    I already shared postmortems from both OpenAI and Hugging Face on the recent security incident when a frontier model broke out of its sandbox to search for a solution for its task. Here is a more detailed writeup by OpenAI on this incident. Given that OpenAI has an intrinsic motivation to advertise their models, I would still take this with a pinch of salt, but it should be interesting. I haven't read this article fully yet, but the start is promising. #ai #security

    Continuing with the topic of AI. A colleague of mine wrote an article on how to attribute the cost with AWS Bedrock with code samples of how to enable it and the description of pitfalls we encountered along the way. #aws #ai #finops

    A nice visualization of Go dependencies. It's interesting how you can instantly see packages that support hundreds, if not thousands, of others. I would have guessed that testify is popular, but I wouldn't have guessed that it's the most popular. Also, I did not expect to see Viper and Cobra being so influential, even though I think they are cool. #go #programming

    An interesting article on how to configure AI reviews for Terraform plans with GitHub Actions and AWS Bedrock. I don’t necessarily like the style of this article, but the content is cool. Now, I need to check how to do something similar with Atlantis. I presume, I could just trigger a GHA on a comment. P.S. This article was brought to you by weekly.tf. If you actively work with Terraform, you may find this newsletter helpful. So, make sure to subscribe! #terraform #ai

    I recall, back in the day, there was a popular interview question: "What would you not automate in your job?" I haven't heard it for a while, but with AI now, maybe it's still relevant. Perhaps it's even more relevant than back then. What SREs Should Automate — and Never Automate — with AI is an article about that. I would argue that the point about security incidents contradicts a bit to what was said earlier: if AI can collect the data for a normal incident, why cannot it do the same for the…

    There will be no digest today because I haven't posted much this week. So, instead here is an article from Anthropic on how to deal with the strain that AI development and reviews put on CI. This is a real problem in the AI-driven SDLC, or so-called "software factories", but unlike code reviews and harnesses, it's not been talked about so much, unfortunately. #cicd #ai
