Alternative to "The C Programming Language by Kernighan and Ritchie"
Found a great book for learning C. Lesson 1 is the usual "hello world", but literally the next example dives into using it as a CGI script. It teaches all the usual C console output stuff, but concentrates on web programming with C and apache web server. This is great, as the terminal is a bit boring looking for the uninitiated, and most ppl are used to booting up and instantly firing up the web browser to click aimlessly on social networking sites.
It includes clean code examples, and moves rapidly on to interacting with mysql and creating images on the fly, while still learning about loop structures etc. At 84 pages of breakneck speed learning, I'd love to hear how a novice gets on with this book. I'm a relatively seasoned C/C++ programmer and I'm still getting mileage out of it.
"C Programming in Linux" by David Haskins.

(If your not a UK IT student just put "abroad" and "other" in drop downs).

Dijkstra & Mathematics Inc.
Pretty funny, this is swiped from the Wikipedia entry for Dijkstra. He's a pretty important figure in computer science.
"One of Dijkstra's sidelines was serving as Chairman of the Board of the fictional Mathematics Inc., a company that he imagined having commercialized the production of mathematical theorems in the same way that software companies had commercialized the production of computer programs. He invented a number of activities and challenges of Mathematics Inc. and documented them in several papers in the EWD series. The imaginary company had produced a proof of the Riemann Hypothesis but then had great difficulties collecting royalties from mathematicians who had proved results assuming the Riemann Hypothesis. The proof itself was a trade secret (EWD 475). Many of the company's proofs were rushed out the door and then much of the company's effort had to be spent on maintenance (EWD 539). A more successful effort was the Standard Proof for Pythagoras' Theorem, that replaced the more than 100 incompatible existing proofs (EWD427). Dijkstra described Mathematics Inc. as "the most exciting and most miserable business ever conceived" (EWD475). He claimed that by 1974 his fictional company was the world's leading mathematical industry with more than 75 percent of the world market (EWD443).[7]"
