Writing books is fun. I really mean that. And part of the enjoyment of my job comes from my "co-workers." While I work from home (or a coffee shop), I still get to interact with a great group of people over at Apress. I say over, but that's not completely true as they're all spread across the globe in different cities and countries. You can read the names of all the people involved in getting this book polished and out the door a few pages back, but I'd like to make sure that Jonathan Gennick and Laurin Becker know just how much I appreciate their feedback and hard work on this book. I really hope to get to work with them again in the future.

I also want to thank Fay Rhodes for her help as the Technical Editor of the book. She found my errors and made sure I got them fixed. And many thanks to the readers of The NXT Step blog who pointed out errors in the first edition and made suggestions for this second edition.

Finally, thanks go to my wife, Ashley, as always... for her support.
