MY OS

Operating-system concepts — boot, processes, memory, file systems — are usually taught as dense theory, which makes them feel distant and intimidating to beginners.

Turn the operating system itself into the learning path: a terminal-inspired environment where each core concept is its own hands-on module.

1. Split the subject into 20 chapters, from boot and initialization to kernel architecture.
2. Implemented the modules in C, built with a single Makefile.
3. Covered security attacks and defenses alongside the core subsystems.
4. Added a shell chapter and a place to write your own commands.
