Along those lines, I think that Rubyists would really benefit from a "Fundamentals of Unix for Rubyists" book (well, not just Rubyists, but you know what I mean). I'm thinking a book at the same level as The Well-Grounded Rubyist--essentially a translation of CSAPP into Ruby. What are the fundamental abstractions that the OS provides you? I know that for me personally, having gotten into programming via Ruby rather than an academic CS background, practically everything having to do with Unix felt like magic. What's a process again? How do pipes work? Wtf is TCP? Everything is a file?
