I would like to take this opportunity to acknowledge some important people in my life who continuously inspire and support me. First, I want to say thank you to my parents Milenko and Stanojka Pavlovic, for everything they taught me, and for all the support they gave me during all these years. Second, I would like to say thank you to my family and my good friends, who helped me become a better person and a better professional. I am very thankful to our excellent team of technical reviewers: Arup Nanda, Gokhan Atil, Dmitri Levin, Osama Mustafa, and Kenneth Roth for their great suggestions and a very helpful feedback. I am also very thankful to Maja Veselica (it was a pleasure writing this book with you), all the editors, and everyone involved in this book.

This is the first book I've written, and because of that, it will always be special to me. I would like to thank my entire family and friends for their patience and support. I am especially grateful to my parents, Mirko and Sanja Veselica, who informally reviewed most parts of the book, and to my uncle Dušan, aunt Zora, and my best friend Mirjana Marković for very creative suggestions.

I am very thankful to the technical reviewers: Arup Nanda, Gokhan Atil, Dmitri Levin, Osama Mustafa, and Kenneth Roth for spending their spare time reviewing this book and for providing us with very valuable feedback (corrections, suggestions, ideas, and opinions). Also, this book couldn't have been written without the Packt Publishing team - thank you all!

Zoran, I always enjoy working with you. Hopefully someday, we'll write another book together.
