Mike Valentine: I’d like to thank my new friends at Skyline for making me feel welcome in the world of official Cisco training. Andy, Frank, Dave, and Toby have elevated my technical and professional expertise and given me great opportunities to learn and grow. It’s my privilege to be a Skyliner.
As always, the good people at Pearson have done their best to direct the energies of an enthusiastic pair of irreverent writers. Brett, Vanessa, Chris, and all the people in the background, thank you for your wonderful work.
Steve Kalman’s guidance has been invaluable; nothing could please me more than to have his sharp eye and careful critique on this book. Thanks, Steve.
Liana and Jaine, you bring purpose and joy to my life. Thank you for apple crisp and pirate princesses.
And finally, thank you to all my students. Remember everything I said.
Andrew Whitaker: Brett Bartow and Chris Cleveland, thanks for continuing to believe in my work.
Steve Kalman, Brian D’Andrea, and Tami Day-Orsatti, you have an amazing wealth of knowledge and attention to detail. I suppose I need to send you all a new supply of Wite-Out now.
Chris Porter, Steve Guadino, and Dave Minutella, don’t worry—this was off the clock.
Jennifer, thanks for sharing me with Que.
The Starbucks on 192nd, thanks for letting me work for eight hours a day on a single cup of coffee.
