Why HN links it
HN readers link this blog for its lock-free concurrency posts, such as a futex post and an MPMC ring buffer. The one comment describes the author's earlier futex post as the reason the commenter wrote their own SPSC buffer.

What Hacker News says?
I wrote my first SPSC circular buffer implementation in TS upon reading the previous post on futex [0] from the same author. It was more intricate than it had seemed, until I finally sat down and wrote my own code. [0]: https://h4x0r.org/futex/ discussion: https://news.ycombinator.com/item?id=44951563
