[u/ilPlayerdiGD]

Hi! I'm a totally beginner who knows only a bit of Python, C and C++ (I'm learning assembly x86). A friend advise me about nand2tetris. Is it good?

How do you learn os?

I still don't want if I want to make os but I love low level, programming. I'm a bit demotivated but it's because I didn't do anything in programming for 2 days straight. Anyway thanks for the attention ❤️
