Revisiting Code

I’m finally rereading Charles Petzold’s Code: the Hidden Language of Computer Hardware and Software, and as with any good book, am getting so much more out of it the second time. I forced myself to study the patterns of dots in Braille until their binary nature became clear, and am now fascinated by his discussion of simple electrical circuits. In some ways it’s stuff I should have remembered from high school, but I’m becoming more and more aware of the vast number of things I’ve long forgotten.
