There's a lot of good (if slightly out-of-date) information in this book, but it is vastly, excessively, repetitive. It seems to be set up so you can skip most of the book, swoop down into one section of a chapter, and use that section without reading anything else. So instructions, sometimes with slight variations, are repeated over and over and over again. This might make sense for a series of blog articles, but it doesn't really make sense for a book.
I remember one of my co-workers asking why I would still buy technical books when everything is available on the internet. And the reason I gave him was that books can make a coherent argument about a complex subject, discussing it in depth. This book reminds me of the joke about the guy who, instead of having 30 years of experience, had one year of experience, repeated 30 times.
