I've actually been reading this book over the past few months. I just stumbled across it while looking for info on neural networks in Ruby. The book takes a very clinical approach, but the code samples are surprisingly accessible.

I haven't bought the book yet (I read it on my iPad), but I will eventually buy it if I can't find a decent digital download. For some reason I'm so much more inclined to buy books offered for free than not.
