NO BOOK IS THE SOLE effort of its authors, especially such a long book. It took long months and countless cups of coffee to keep us awake and writing and programming the code examples. We could not have made it through this if not for the help and patience of many kind souls.
First of all, we want to say a big THANK YOU! to the Wiley/Wrox team we had the pleasure of working with. Carol Long showed great patience and motivated us when we were down. Tom Dinse and Nancy Sixsmith worked hard to get our English right. Wim Mostrey made sure that all technical matters are 100% correct. Ashley Zurcher helped to successfully deliver the book to the market, and Helen Russo took care of our legal matters. It was really fun to work with you folks!
We also want to thank our superiors on the faculty of Physics, Astronomy, and Applied Computer Science of Jagiellonian University in Kraków: dr hab. Ewa Grabska, prof. dr hab. Maciej Ogorzałek, prof. dr hab. Maciej A. Nowak, and dr hab. Paweł Węgrzyn, who were really supportive and did their best not to swamp us with additional jobs while we were busy writing.
Finally, our thanks go also to all the developers who dedicated their precious time to write good documentation and share their knowledge.
