The number of people who deserve their name on this page for making this possible would require a book of its own, so allow me to start by apologizing if your name isn't here by saying: I owe you a hug and a big "thank you".

To my grandparents and my family for allowing me to follow my ambitions. My friends, Xeba and his wonderful family, Mathías and Eliana, Bruno, Lore, Ce, and Dan for putting up with this project of mine. Without your encouragement and support, this could have never been completed.

My colleagues, particularly Gabriel, Diego, and Ale, for their feedback and for getting me through those particularly difficult times around Chapter Four. To the technical reviewers Alice Ferrazzi, Chien-Wei Huang, and Takeshi Banse; and staff at Packt Publishing for their great suggestions and eagle-eyed corrections.

So now you know, if you don't see your name in here, come by with a frowning face, and you'll get that much-deserved hug. I promise.

So see you around and again, thank you.
