It required a lot of work to compose this book. I could not have done this without the help of these people:

The team at Packt Publishing and the reviewers of this book, because of their precise feedback and hard work. This has helped me a lot to improve the quality of this book.

My fellow students, for brainstorming and helping on specific topics.

My teachers at Utrecht University, for giving inspiration and challenging me on various topics. I especially want to thank Jurriaan Hage for supervising my thesis.

Finally, my family, for their support and tips, even though they did not have knowledge on these topics. These people have helped me to to make the book as it now lies in front of you.
