Thanks for the link! I've been accumulating a library of PDF books, articles and cheat-sheets that I can carry around on my development laptop and always welcome another resource. You may find it funny now, but 5 years ago I almost always carried a couple of paper books in my suitcase when I traveled on business. My back is much happier now!
