First of all, I would like to thank my co-author, Marcel van der Plas. Thanks to the easy way that we could work together, the writing of this book has gone as smooth as possible.

I would like to thank the people at Packt Publishing for offering me the chance to write this book. It has been a long process with a lot of hard work, but I'm very happy with the result. I also would like to thank Douwe Pieter van den Bos for introducing me and Marcel to Packt Publishing and his invaluable help in the early stages of the book.

Furthermore, I would like to thank all reviewers for their hard work in reviewing our drafts. This book has become so much better; thanks to 
you guys.

I would also like to thank my employer, Whitehorses, for the support that I have been given.

And last but not the least, I would like to thank my family for their love and support. Without the help of my wife Jamila and the "dikke kroelen" from my daughters Naomi and Aniek and my son Kris, this result would not have been possible.
