I just skimmed the table of contents and then read two sections. This looks like a great resource for systems programming. In modern times, anyone with a Linux laptop can get their feet wet. When I was young, I had to leave a job I liked (I eventually went back) to get a job doing real time systems programming on a multics-based system (Prime). That period of time forever changed my mental model for computing systems. UIUC is a great school. My last job before retiring was managing a deep learning team in the UIUC research park. The university had a great technical buzz, and the undergraduate CS interns we hired were talented and hard working.
