Paweł Dziepak's personal blog at pdziepak.github.io covers systems and programming. Since 2019, 3 different Hacker News readers have linked it 6 times, most often “On GPUs, ranges, latency, and superoptimisers”. It is still writing: the last post was on 2025-06-05, and you can follow it by feed.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
Linked as a 2019 post on how LLVM MCA can guide low-level optimizations, covering lists, cache behaviour and algorithms. One commenter pointed to it as a follow-up to the LLVM MCA submission.
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.
Largely arbitrary programming notes by Paweł Dziepak.

What Hacker News says?
This is really cool! I wanted to point out this wonderful article also posted to HN today that shows how LLVM MCA can help guide low level optimizations: Article: https://pdziepak.github.io/2019/05/02/on-lists-cache-algorit... HN: https://news.ycombinator.com/item?id=19810618
