This book never fails to inspire me to write code. It is one of the few computer books (perhaps along with this) that I can say actually affected my perspective on programming. Since programming is as much a part of me as performing music is a part of a musician, these two books have had profound effects on my life.
As much as I like toying with hardware, at the end of the day I am a programmer. I may no longer care to follow the current fads and coding crazes, but I still love to code.
I'm hoping some bedtime reading of the former (Literate Programming) will help cure my current programming humdrum.
