Is Charles Petzold a guilty pleasure for you?

9780735605053fCharles Petzold was mentioned yesterday in a New York Times Magazine article, “Stuff We Like That Maybe You Won’t.” Someone on the staff and contributing to the article said,

My friends are (mostly) not interested in the history of electrical engineering, which is the subject of Charles Petzold’s “Code.” I find it gripping!

We’re pretty sure many of you find the book gripping, too. Tell us about it. Is it a guilty pleasure? A thriller, as Charles builds his explanations, switch by switch, diagram by diagram? A book you give to friends and never get back? 

If you’re unfamiliar with Charles’s classic, here’s a description:

What do flashlights, the British invasion, black cats, and seesaws have to do with computers? In CODE: The Hidden Language of Computer Hardware and Software, they show us the ingenious ways we manipulate language and invent new means of communicating 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.

Using everyday objects and familiar language systems such as Braille and Morse code, author Charles Petzold weaves an illuminating narrative for anyone who’s ever wondered about the secret inner life of computers and other smart machines.

It’s a cleverly illustrated and eminently comprehensible story—and along the way, you’ll discover you’ve gained a real context for understanding today’s world of PCs, digital media, and the Internet. No matter what your level of technical savvy, CODE will charm you—and perhaps even awaken the technophile within.

Make sure to read David Wall’s editorial review at Amazon as well. Here’s a snippet:

It's a carefully written, carefully researched gem that will appeal to anyone who wants to understand computer technology at its essence. Readers learn about number systems (decimal, octal, binary, and all that) through Petzold's patient (and frequently entertaining) prose and then discover the logical systems that are used to process them.

  • CODE is one of the best books that I have ever read.  I was teaching a college CS course and the text that the university assigned was just dreadful.  I "went rogue" and used CODE as the text instead.  Later one of my students, who taught children with disabilities, told me that he used that book with his students.  They went to Radio Shack and bought a bunch of relays and other components and actually built a rudimentary computer based up the ones in CODE. Its amazing that something as simple as a little book can actually touch peoples lives.
