Based on the comments I see here (about how they wished to learn CS, or CS vs EE), I wish this book had a different title with more of an indication that this is a operating systems book (though not 100%). Computer Science is more than what is presented here.

Big O Notation/Data Structures/Algorithms, ala Dr. Knuth

Proof and theorems

Computer architecture and design (NAND gates and the like)

Language design, interpretation, and implementation

...and much more.

Do not get me wrong, I believe this book is valuable (BIG 'THANK YOU' to Ian Wienand for it). I just wish the title could have been different.
