And if anything qualifies as esoteric, arcane knowledge, it’s embedded systems programming
I’d say OS and driver programming is also in that category. It is the deep magic.
True, true. I have a vague idea how embedded systems work. I have no idea how you even get started with driver development.
OS development isn’t terrible though. There are numerous books to help you make your own kernel and OS
For linux driver development you can start by reading “Linux Device Drivers, Third Edition” pdf.
It is free and give you an idea about how everything works.
The real learning is by reading and using the linux kernel api doc or directly the source code of the api you want to call.
Source : i did this for a school project where i had to implement multiple kernel modules.
