Acknowledgement

Almost every book starts with some words, in which the authors thank people who have supported him/her and allowed him/her to finish the writing of the book. Following this nice and proper tradition, I would also like to thank the people, without whom this book would not have come into existence. First of all, I would like to thank to my wife, Hania, who supported me all the time and forgave all my whims while I was writing, taking care of our home and our son, and forgiving me for spending less time with them.

I would like to thank my parents who bought me my first computers and who always took care and trusted in me, even if my decisions seemed controversial to them. Without their acceptance and trust, I couldn't have realized my passion and started to make a living by founding a small IT company.

I would like to thank the rest of my family and my friends, for their patience and understanding while I was writing, as I didn't find time to meet them.

Last but not least, I would like to thank the people from Packt Publishing, who gave me a chance to write this book and did a great job, spending a lot of their time and work by correcting my initial drafts and providing valuable suggestions. Without their experience, knowledge, and commitment, I wouldn't have been able to finish this project.
