Patryk Wychowaniec's personal blog at pwy.io covers programming and games. Since 2021, 8 different Hacker News readers have linked it 19 times, most often “Kruci: Post-mortem of a UI library”. It is still writing: the last post was on 2025-08-21, and you can follow it by feed.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers link Patryk Wychowaniec's blog for its introductory guide to Rust, deep learning and genetic algorithms, 'Learning to fly', which is linked as a starting point for combining genetic algorithms with RL.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
Curiously enough, I've used to work in hospitality! ( https://pwy.io/posts/mimalloc-cigarette/ & https://pwy.io/posts/memory-for-nothing/ ) Our dataset wasn't so large as to warrant experimenting with GPUs - `cost(extraCpu) < cost(developerExperimentingWithGpus)` - but the CPU implementation got a lot of love; it was mostly engineering-based work, though ("how to load stuff from the disk effectively", "how to make i…

HN discussion> anyone has looked into using genetic algorithms combined with RL where the genetics determine the reward function There is an introductory guide to rust, deep learning and genetic algorithms that I really like, it's called "Learning to fly" [^0] [0]: https://pwy.io/en/posts/learning-to-fly-pt1/
