> learn to develop complex system-level software in the C programming language while gaining an intimate understanding of the Unix operating system

I would have loved to take a course like this in college, though I didn't have the chance. I do think [Rust In Action](https://www.manning.com/books/rust-in-action) is a good introduction to some of the same concepts, if anyone is, like me, yearning for grad school while having to hold down a job. While it doesn't use C, I think it teaches systems programming in a way that's easily applicable to any language.
