An early chapter talks about Hamming Codes.

I've only worked through the first few chapters, but I recommend it. It seems to be a unique book.

I recommend the book in general, and also his lectures. He has a quirky sense of humour, compares his book with Harry Potter here: http://www.inference.org.uk/mackay/itila/Potter.html
