* Godel Escher Bach

An ambitious work that's hard to describe, Douglas Hofstadter weaves history, maths, geometry, music, fictional Socratic dialogue and a hell of a lot of recursion into a investigation of Godel's infamous paradox at the heart of mathematics. I read it as an undergraduate and it was mind blowing at the time.

* The Poignant Guide To Ruby

A weird and captivating journey that I found in my early years as a programmer. Though I never actually wrote much Ruby in the end.

* Modern Operating Systems by Tanenbaum/Bos

The most normal textbook. It's a doorstopper that covers a lot. I just liked it for some reason (I loved the course too) and I've kept it around.

Many more that I'm sure I've forgotten.
