Code: The Hidden Language of Computer Hardware and Software by Charles Petzold

4.0

A great book on the beginning era of computes and how/why they work the way they do. I wish I would've read this book 10 years ago. At times the EE specs and assembly code was terse and hard for me to follow but it's a must read for any programmer.

My favorite quotes:

1. "Code is not like other how-computer-work books. It doesn't have big color illustrations of disk drivers with arrows showing how the data sweeps into the computers. code has no drawings of trains carrying a cargo of zeros and ones. Metaphors and similes are wonderful literary devices but they do nothing but obscure the beauty of technology."

2. "The amount of water flowing through a pipe (current) is directly proportional to the water pressure (voltage) and inversely proportional to the skinniness of the pipe (resistance)."
