I wouldn't even bother with books any more after you're done with that one. By the time they come out the "solutions" that were published there become either obsolete or not as efficient as the ones that you can find on web sites. Besides, I just love when a book claims to be "The Ultimate", "The Final", "The Most Comprehensive", etc. and then when attempting to discuss a certain aspect of the architecture states that "this topic is outside of scope of this book..." Go figure, hey?! Web sites on the other hand are free and plenty, so are boards like this one.
