Two stars for what its worth. I'm dissatisfied with the way this book is written. Its not straight to the point and lacks substance. Although some chapters proved to be informative like (i.e. chapter one: foundations) they could still be found from other resources like the internet (and its free!!). (translation: i regret having spent my money on this book). The book was a dissapointment i thought id be reading the thoughts of a real seasoned expert, i was wrong. Now Veen will be in my "ignore the books of this writer" list.
