os01: Bootstrap yourself to write an OS from scratch. A book for self-learners (tuhdo.github.io)

Oi too many. I keep a few as favourites in my HN (favourites are public, mine are here: https://news.ycombinator.com/favorites?id=Gunax). There was another OS guide from a few days ago (https://news.ycombinator.com/item?id=28774022) that i also saved there.

I actually prefer this one, but I want to make a OS for the pi so maybe i can like... Adapt it to ARM.

I also have a few hundred links i have saved as Firefox bookmarks under a category 'learn' over 10 years... Some are tutorials, some just blog posts or reddit comments.

I actually have gone through some of them, and once in a while I will come upon an issue that I know i saved back in 2015 or whatever. I know I will never go through most, but the cost of saving it is small and sometimes it helps.
