Query: Disappointing!!!

There is some useful information, but it's normally very hard to find because there is TOO MUCH DISTRACTING information such as kayaking and Mount Everest. Reading this book is very tiring because you have to try hard to separate the author's good programming advice from his programming career and, again, his kayaking experience. I am sure if the author tried hard enough to sum up the whole useful information, this book could be as thin as 50 pages.The author has to decide whether he wants to be a novelist or a computer book author...
