Wow, hackernews is a cesspool of self-serving "intellectuals". We're in the middle of a pandemic, which already killed 27 thousands people. And the #1 post is privacy act? Can't you guys admit that you didn't come up with video calling company worth 37 Billion dollars. Maybe it's worth talking the positive impact on Zoom during this crisis.
Not very good to be honest. Nothing about schedulers, bootstrap, and most of it is very general information. it doesn't give actual clear picture how everything comes together, and it is very system specifics (unix). CS should be agnostic to any system architecture. You do cover binary , but the more fundamental question what is the foundation of binary mathematics. It goes back to Turing machine, and how transistors are built and how you compose them into bigger units, and then you talk about CPU architecture, the adder, multiplexer, the PLU, etc.
