If anyone with some #statistics or #mathematical inclination is looking for a good way to get into computery stuff, I heartily recommend Data Analysis With Open Source Tools. It seems like a good way to apply modern stats to large data sets.
I wish I could recommend it to computer people wanting to learn more mathematics, but I think the mathematics in the book might be scary, since it's not often explained from first principles. It seems better for the other direction.
