I'm currently going through TAOCP[1]. So far, seems pretty good (although I found one mistake in an exercise).
Also, I can never recommend Computer Systems: A Programmer's Perspective[1] enough. (Also features a rare mistakes in an exercise or two, but that's detail.)
And for network protocols, Comer's Internetworking with TCP/IP[3] was just great (you only need volume 1). I've read Stevens' books on socket and IPC programming in Unix, but didn't like them, so I also stayed away from TCP/IP Illustrated, but others have different opinions.
