It interesting to see a completely different background to mine. If I have one criticism of this list it's that it is very mono-cultural -- all OOP, nothing FP here, for example.

My background is K&R, Code Complete, SICP and related books in the Scheme canon (HtDP, PLAI), and lots and lots of papers and blog posts. Having absorbed the fundamentals I find online material both more accessible and up to date.
