These are really well written guides. They are more readable and enjoyable to read than many programming books published for adults today. I've often wondered why programming books don't use simple graphics or diagrams to illustrate programming concepts. Anyone writing a technical guide (of any kind) would benefit from reading these as a source of ideas and inspiration.
