It appears as if most of the earlier reviews for this book were for the first edition. (Which brings up a good question – WHY is this book now useless?)
As with essentially every other book I’ve spent $40 – $50 for, this one is filled with poor content and code that does NOT work. If you look at the “sample” website for this book that uses the code that this book is supposed to help you build (http://apress.mediatemple.net/site/news/), many people hit a roadblock by page 28! The site is filed with comments from others who have been stuck on the same problem and can’t move on. Perhaps the most revealing question there is “has anyone been successful in getting all the way through the book?” Not surprisingly, no one has answered.
The publisher’s site (http://www.apress.com/book/bookDisplay.html?bID=200) also does NOT include an errata sheet (that would be asking too much).
Don’t bother buying this one – unless you enjoy throwing another $50 down the toilet. I bought this book based upon the positive reviews found here – little did I realize that the second edition must be worse than the first!
