Hello! Understanding Computation is (I hope) a fun and interesting book about computation theory, with explanations written in real Ruby code instead of mathematical notation. It contains old, deep ideas from theoretical computer science, deconstructed and explained in an engaging, practical way for an audience of working programmers without assuming any academic background.
The focus is on answering questions about computation and the fundamental mechanics of programming languages: how do they really work? what can they really do? what do the programs we write in them really mean?
