What do flashlights, the British invasion, black cats, and seesaws have to do with computers? In CODE, they show us the ingenious ways we manipulate language and invent new ways to communicate with each other. And through CODE, we see how this ingenuity-and our very human compulsion to communicate-have driven the technological innovations of the past two centuries. Now in paperback edition, this critically praised book weaves an inventive and eminently comprehensible narrative for anyone who's ever wondered about the secret inner life of computers and other smart machines. The work of legendary computer book author Charles Petzold has influenced an entire generation of programmers. And with CODE, Microsoft Press is proud to share this gifted teacher and communicator with every reader interested in understanding today's world of PCs, digital media, and the Internet.
