Two thirds of the book are about nothing. If the book was completed only on 100 or 150 pages ("the best of"), i could give 3 stars..
It is a bit chaotic ordered, there are mistakes in that book and author often uses magic formulas "If you need do this, do this: ...". The book is much more about How, not Why.
If you have some experiences with programming in any language, buying subj. is only wasting money..
