This week we go super deep into analyzing the x86-32 cdecl ABI, calling conventions, etc - in order to understand and eventually implement a working stack-based backtrace function.

Welcome! This is my chill Operating Systems development "gardening" project.
The "gardening philosophy" is to have fun, above everything else. This means taking baby steps and locking in small wins before building up for more ambitious projects. People also call this "hacking" on something.
My personal goal & vision is to build a minimal, high quality OS foundation which can be used for play, experimentation, and learning.
I'm personally not an expert systems programmer, although I'd like to be someday. Right now, but I'm just an intermediate one - I worked in infosec for 7 years, and music tech for 3 years. I've been exposed to the Linux kernel in both settings, but in highly constrained contexts, and mostly reading code, not writing it.
