Acknowledgment

I would like to thank my wife for putting up with my late-night writing sessions. This book would not have been possible without her devotion. I would also like to give thanks and gratitude to the editors, Akash, Susmita, and Kevin, that patiently guided me. They are the source of continuous encouragement.

I would like to thank my guru Dr. Vijay Gokhale Sir, who taught me a lot more than OS. I would also like to thank my friends, Omkar Kulkarni and Ashish Shah and online friend Swiftgeek, who helped me with the electronics concepts. Also, I thank my friend, Amit Karpe, for introducing me to Packt Publishing. I thank Mrs. Nutan Chaudhari, who gave me her BeagleBone White for the purpose of testing. I used Fritzing software to draw the circuit diagrams throughout the book. I would like to thank the Fritzing team. I also thank the BeagleBoard crew for creating wonderful open source hardware boards. Finally, I would like to thank the entire open source software movement.
