I've been diving into this operating systems course https://classroom.udacity.com/courses/ud923/ https://classroom.udacity.com/courses/ud923/ in my free time, It's about 9 years old I think, but it's been very enjoyable Earlier this year I embarked on a project to help me learn how CPUs work, I ended up implementing simulator for a simple CPU from the "But how do it know?" book - I have a blog post about it if anyone is interested. Since then I've been dabbling with learning about RISCV, but it's been slow progress.

I'm interested in that simulator, it sounds fun! I started reading 'But How Do It Know' a while back; I never finished it but I can say that it was a very fun read. I've heard that 'From Nand to Tetris' [0] is also quite a worthwhile read. A quick look shows that it not only has a link to a book [1] but also some freely available notes/lectures as well as some exercises.

  Yeah From NAND to Tetris is probably a better more structured approach, I kind of just went off and did my own thing but I'd imagine it's more fun to get something playing Tetris!

  I'm partway through Nand to Tetris right now, and I'm really enjoying it! It's taking me quite a while, as I'm doing it in C (which I have no experience with) as a way to start making my way towards embedded programming, but it's a really rewarding course.
