It's Drew Conway. The guy is good, and he makes complex things very accessible. Sometimes, you need to understand the matrices behind the process, and that's great, lots and lots of books out there about the math. But sometimes you need to group up some data and you need a quick way to get it done mostly well. There aren't as many books out there to do this as there should be, and I look forward to this one.
