Query: Overrated, but does have utility - 2 stars max

This book is overrated, but it does have utility in bringing to your attention design patterns --which should be obvious to any good programmer--such as the Singleton (object only capable of instantiation once).Why do I say obvious? Because any programmer worth their salt will over time develop their own home-grown library of patterns and exemplars to reuse. This book merely calls attention to this habit.Also, as other reviewers have pointed out, the text is too generic and abstract, unless you're into that. Donald Knuth anybody?Plus the book is too expensive--if you must, buy it used like I plan to. That's right, I haven't read it yet. But I know enough just reading these reviews; sometimes you CAN judge a book by the cover. I am over the age of 13, yes.
