I've struggled with a lot of mumbling-jumbling programming books and wondered why programming book can be so boring and difficult. Only after reading this book, I understand a lot of authors either don't know what they are talking about or don't really make an effort to make their books useful. Mr. Linden knows exactly what he talks about and make it as simple as possible to understand. Einstein used to say that everything should be as simple as possible but not simpler. Mr. Linden has achieved that. If there were an award for writing good programming book, he certainly deserves one. Thank you Mr. Linden for writing such an excellent book.
