Read Code: The Hidden Language of Computer Hardware and Software by Charles Petzold
Notes
The key word here is two. Two types of blinks, two vowel sounds, two different anything, really, can with suitable combinations convey all types of information.
Petzold
Started reading Code by Charles Petzold, which has been on my reading list for a while. I like the way the book starts from the premise that code is a way to communicate. “A code is useful if it serves a purpose that no other code can,” Petzold writes. Morse code and Braille were created as a more convenient way to communicate than existing alternatives. Both are made up of binary elements—a dot or a dash for Morse code, a raised dot or flat dot for Braille. From here, we’ll go on to see how code is used to store and communicate information in computers.
