Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
HN readers link downey.io posts on Raspberry Pi hardware, such as heatsinks and throttling, running Folding@home on a Pi, and writing an OS in Rust with Stanford's CS140e course.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Personal blog containing thoughts on software development, lifelong learning, photography, etc.

on “Ask HN: Where to start writing a OS/kernel?”I forgot all about this project - thanks for the reminder! You can run on a spare Raspberry Pi. I remember doing that. Performance isn’t great but every little bit helps https://downey.io/blog/folding-at-home-raspberry-pi-arm/
