From Assembly to OS: Building a C Compiler from Scratch

Tumble Forth – from assembly to OS with C compiler

Virgil Dupras, creator of Collapse OS and Dusk OS, launches a series guiding web developers into low-level programming. Starting from bare metal on the PC, readers build a Forth, then Dusk OS, and finally a partial C compiler—all from scratch. The series targets programmers new to low-level work, with each episode including a corny joke.

We peek in disgust in the abyss of modern software complexity and escape this dystopia by tumbling down the rabbit hole of low level development.
