You know how it is: you pick up a book, flip to the dedication, and find that, once again, the author has dedicated a book to someone else and not to you. Not this time. This one's for you. It is dedicated to all Enthusiast Evangelists and when you read it, you'll probably know why.

Along with you, I dedicate this book to my father, Ramesh Chandra, with love (actually, dad does not read technical books; he will never know about it unless someone tells him). A huge thanks to my wife, Richa, and son, Noah. Thanks for being patient with me while I was out at lakes and coffee shops writing, and could not spend weekends with you. Thank you for your sacrifice of weekends and vacations, and I'm sorry about that.

I would like to express my gratitude to Bill Swenton and Teresa Short for their support. I'm honored to have had Mark Rakhmilevich offer his guidance on the book.
I'm highly thankful to Nimesh Prakash and Anand Eswararao Yerrapati for joining me as coauthors of the book. You have enhanced the depth and value of the book multifold. I would like to express my deep gratitude for your generous support.

I'm deeply thankful to Navroop Sahdev, David Gadd, and Mary Hall for writing a foreword for the book. It certainly adds value to this edition. My deepest gratitude to you.
I would like to thank the talented team at Packt, including Aditi Gour and Roshan Kumar, who provided guidance, feedback, and added value to the book. I'm extremely thankful to the reviewer, Srihari Rayavarapu, who provided constructive and very useful feedback that helped us to tremendously improve the content of the book.
