Acknowledgement

While writing this book, I was fortunate to work with an excellent team at Packt Publishing, whose contributions vastly improved the presentation of this book. James Lumsden helped me to transform the idea in the final book and gave me first steps, while working with this book for Packt. Poorvi Nair made everything easier with both her incredible time management and patience. Reshma Sundaresan helped me realize my vision for this book and provided many sensible suggestions regarding the text, the format, and the flow. The reader will notice her great work. Vinodhan Nair and Erika Fernandes made the sentences, the paragraphs, the pictures and the code easier to read and to understand. They added great value to the final drafts.

I would like to thank my technical reviewers and proofreaders, for their thorough reviews and insightful comments. I was able to incorporate some of the knowledge and wisdom they have gained in their many years in the software development industry. The examples, the pictures, and the code include the great feedback provided by Marius Constantinescu, Laurent Duveau, Russell East, and Vikram Pendse. This book was possible, because they gave valuable feedback.

I must acknowledge David Barnes, Beginner's Guide Series Editor at Packt Publishing. His help in my first book published by Packt and his wisdom are also part of this new one.

I wish to acknowledge Hector A. Algarra, who always helped me to improve my writing.

Special thanks go to my wife, Vanesa S. Olsen, my son Kevin, my nephew Nicolas, my father Jose Carlos, who acted as a great sounding board and participated in many hours of technical discussions, my sister Silvina, and my mother Susana. They were always supporting me during the production of this book.
