Acknowledgments

Since I was hired by Red Hat Inc. more than six years ago, I have been exposed to many of the best Linux developers, testers, support professionals and instructors in the world. Since I can't thank everyone individually, I instead salute the culture of cooperation and excellence that serves to improve my own Linux skills every day.

I don't speak well of Red Hat because I work there; I work at Red Hat because it lives up to the ideals of open source software in ways that match my own beliefs. There are a few people at Red Hat I would like to acknowledge particularly. Discussions with Victor Costea, Andrew Blum, and other Red Hat instructors have helped me adapt my ways of thinking about how people learn Linux. I'm able to work across a wide range of technologies because of the great support I get from my supervisor, Adam Strong, and my senior manager, Sam Knuth, who both point me toward cool projects but never hold me back.

In this edition, particular help came from Ryan Sawhill Aroha, who helped me simplify my writing on encryption technology. For the new content I wrote in this book on Linux cloud technologies, I'd like to thank members of OpenStack, Docker, and RHEV teams, who help me learn cutting-edge cloud technology every day.

As for the people at Wiley, thanks for letting me continue to develop and improve this book over the years. Marty Minner has helped keep me on task through a demanding schedule. Mary Beth Wakefield and Ken Brown have been there to remind me at the times I forgot it was a demanding schedule. Thanks to Richard Blum for his reliably thorough job of tech editing. Thanks to Margot Maley Hutchison from Waterside Productions for contracting the book for me with Wiley and always looking out for my best interests.

Finally, thanks to my wife, Sheree, for sharing her life with me and doing such a great job raising Seth and Caleb.
