Query: a mediocre title

While some of the information is pretty interesting, most of it isn't, and some is outright self evident, such as abstraction concepts. In the year since I've read this book, I haven't opened it again and never used a single concept from it. That should tell you something about how relevant it is.It is really supposed to be for beginners, but I don't think beginners would find this text very user friendly or easy to understand. I know I had trouble in some parts and I'm not a beginner. In fact, I was forced to take this course as a computer science major at MIT. I've had a fair number of discussions about the book with various students. Few, if any, liked it.In short, it's just your average book, and definitely not worth the price, or your time. It has no earthshattering things to teach you.
