Rich Hickey is a genius. I love how he connected music to software engineering [1]. He should write a book on some of these topics. He has a lot more than 45 mins talks to offer to the world.
I've been waiting for a book that elaborates on simple design a la Hickey (with some examples/code) ever since I saw the "simple made easy" talk. If there is one that I missed, I'd love to know.
