I would like to first and foremost thank my beautiful wife, Maro, who put up with my exhausting writing schedule for both this book and my PhD thesis, while staying focused enough to organize our wedding. I would also like to thank my parents and my brother for their continuous support, especially during this past year. Without the encouragement from all of them, this project would never even have got started in the first place.

I would also like to thank everyone at Packt Publishing who got involved in this book, especially Joanne Fitzpatrick, Hardik Patel, Navu Dhillon, and Anila Vincent. They played a very important role in helping me understand the rationale behind such a writing project and provided invaluable feedback throughout the writing process. Also, a special thanks goes to the reviewers, R. Surya Murali, Ashish Uthama, and Alexander Wright, who provided very useful and insightful comments and suggestions for improving the quality of the book. Without them all, this book would never have reached its publishing stage.
