Greg Wilson and Andy Oram provided a great edited collection of developers explaining their code in Beautiful Code : Leading Programmers Explain How They Think. I wrote about seeing the book at FooCamp.
“I find that I often learn a lot about coding problems and techniques by looking at other people's code. This book excites me because it is the first time I can remember other than maybe Knuth's The Art of Computer Programming where there was commentary about the beauty of code and algorithms. And for some reason, this book will be a lot easier to read than TAOCP.”—David Crow
