Patrick Gaumond published detailed review of my TYPO3 extension programming book. Here is one quote from his review:
One of my first feelings once I started to read the book was that it will become the de-facto manual for Extension Development courses given by agencies all over the world. It’s really the kind of book you don’t want to skip a paragraph, fearing you’ll miss some good advice. Succinct is a quality.
All in all, it’s a very good book for starters; a very important book to hook some PHP newcomers into the TYPO3 world and a great step for better comprehension of this fabulous principle Kasper gave us 6 years ago when he presented the Extension Manager.
