Title: Do not purchase this book if you don't need a 250 page resume!
Review: I can not believe how anybody who has read this book would honestly give it a 5 star. I read the whole book, waiting for that moment that I could say: Oh, that's what the author meant by repeatedly saying: "more to come later" or "we'll see this in later chapter" etc. That moment never arrived. This book looks like a hurried and lousy compilation of 5 day presentations on each subject that this books claims to cover, without proper editing and attention to detail.I read the book riding the metro in Washington DC and I can honestly say that I would rather see DC tourists block the left side of the escalators in the metro stations on a busy rush hour day than read or refer to this book again
