Wow. Thanks for sharing. I had no idea that Professor Remzi and his wife Andrea wrote a book on Operating Systems. I loved his class (took it almost 22 years ago.) Will have to check his book out.
I can highly recommend CS50 from Harvard (https://www.youtube.com/@cs50). Even after being involved in tech for 25+ years, I learnt a lot from just the first lecture alone.
Disclosure: Professor Malan is a friend of mine, but I was a fan of CS50 long before that!
