I'm reading Code right now and it's fantastic. I'm a bit more than 1/2 the way through and so far it's only been about how computers work and not really about computer science.
I heard an expression this weekend that I think is apt - a computer is to computer science as a telescope is to astronomy.
"Calling it 'computer science' is like calling surgery 'knife science'."
(Also, "CS could be called the post-Turing decline in the study of formal systems." But I don't know for sure if that was Dijkstra. It's one of my favorite jokes.)
