Title: I didn't like it at all
Review: I have read other's review on this book, and then purchased the book. Though it contains some useful stories, the book lacks of anything really useful. Lots of comments, math, model without any proof and/or reference. I really wasted my money, and time to read the book witch contains virtually no information.
