Exclusively C-themed.
Corg-Labs is a collection of projects, experiments, and learning resources written in C — focused on understanding systems from the ground up.
This org is about:
- Writing real C.
- Keeping things simple, fast, and close to the metal.

- Pick a repository
- Read its
README.md& go through the Tutorial. - Build, break, and understand the code
- No unnecessary abstractions
- Prefer clarity over cleverness
- If you don't understand it, rewrite it
Because understanding computers starts here.
