To my son, Adam Sanghera, the thinking man Who can walk the sky and talk the land To venture to a beach for a crab grab And play with the waves under sea's command To command the music to enable my eyes To see the universe in a grain of sand

Acknowledgments

As they say (well, if they don't any more, they should), first things first. Let me begin by thanking Scott Rogers for not ignoring my first email to him, which finally led to this writing project. My sincere thanks to both Scott Rogers and Timothy Green for offering me the wonderful opportunity to write this book. With two thumbs up, thanks to all the incredibly hard-working folks at Osborne: Tim Green, Jessica Wilson, and Jennifer Housh, for their team spirit and professionalism, which made this project a smooth ride.

I am thankful to Nalneesh Gaur, the technical editor of this book, for doing an excellent job in reviewing each chapter and offering valuable feedback. It is my pleasure to acknowledge the hard work of the production team at G&S Book Services, in particular, Katherine Bishop, the production coordinator, and Harlan James, the copy editor.

In some ways, writing this book is an expression of the technologist and educator inside me. I thank my fellow technologists who guided me at various places during my journey in the computer industry from Novell to Dream Logic: Chuck Castleton at Novell, Delon Dotson at Netscape and MP3.com, Kate Peterson at Weborder, and Dr. John Serri at Dream Logic. I also thank my colleagues and seniors in the field of education for helping me in so many ways to become a better educator: Dr. Gerald Pauler, Brooks College; Professor David Hayes, San Jose State University; Professor Michael Burke, San Jose State University; and Dr. John Serri, University of Phoenix.

Friends always lend a helping hand, in many visible and invisible ways, in almost anything important we do in our lives. Without them, the world would be a very boring and uncreative place. Here are a few I would like to mention: Stanley Huang, Patrick Smith, Kulwinder, Major Bhupinder Singh Daler, Ruth Gordon, Srilatha Moturi, Baldev Khullar, and the Kandola family (Gurmail and Sukhwinder).

Last, but not least, my appreciation (along with my heart) goes to my wife Renee for not getting irritated with my using the living room as the author room to write this book.
