Query: A frustrating waste of time.

The book starts out great, explains things in a way that makes sense and leads you to believe that you're fixing to learn something. But......it is so full of mistakes! There are so many code errors and figures that just don't jive. After the 7th code mistake by Chapter 9, I quit. I felt like the publisher should send me my money back, as well as a check for proofreading the book for them. Skip this book!
