Let's try to gather together some /high-quality/ resources for learning how to write complex systems software.
I'll list off the ones I'm aware of, and if you know of some others, please comment below! :-)
– Crafting interpreters by Bob Nystrom
– Building git by James Coglan
– The raytracer challenge by Jamis Buck
– Codecrafters (docker, redis, git, grep, http server, sqlite, torrent)
– Various awesome lists on Github which aggregate content scattered in blog posts all over the web
– Perhaps some YouTube videos
What about handrolling a kernel, for example?
