Dedications

As always, this book is dedicated to the most important people in my life: my wife, Marci, and my two little daughters, Lauren and Kara. Their love, encouragement, and support carry me along. I’m so grateful to God, who gives endurance and encouragement (Romans 15:5), and has allowed me to work on projects like this.

I would also like to dedicate this book to the memory of two close relatives whom I’ve lost this year:

Ralph Hucaby, my uncle, a fellow EE, and a pioneer in the television industry, who always had an interest in my technical pursuits for as long as I can remember.

Phyllis Wilson, my mother in-law, who never owned a computer or touched a network, yet was genuinely interested in my writing projects. Her friendship and good cooking will always be missed.
