Query: Stay away from this book!! Its a waste of paper...

This book is not for beginners, and contrary to the reputation of O'Reilly press, this is not for experts.The book uses a simple way to discribe many cases of things going bad. But it stays on the superficial layer of the problems.The paradigm it uses is describe the problem, ways to prevent it, and how to get off the hook. This may seem very tempting to read because of the easy way to analyse the content of the cases. I like the 3 step aproach, but I didn't see and substance of the way she explained and the conjectures of details each process entails.The book in general is a simpleton... and its boring.
