Acknowledgments

I would like to acknowledge the FreeBSD, OpenBSD, and NetBSD development communities, who have continued the noble tradition begun by the Berkeley Software Distribution decades ago. Their efforts have led to some of the most secure and stable computer operating systems in or out of the free and open source software world.

Special thanks to François Caen for giving up most of his free time over the past year as we developed and wrote the books in our Toolbox series. Thomas Blader did his usual excellent job tech editing this book. At Wiley, I'd like to thank Jenny Watson for sticking with us through the development of the book. Special thanks to Bill Bridges, who kept us on track during a challenging development schedule.

—Christopher Negus

I would like to thank Chris Negus for giving me the opportunity to co-author this book with him. We had wanted to write together for the last couple of years, and this Toolbox series was the perfect fit for our collaboration.

I couldn't have worked on this book without the unrelenting support from my wife, Tonya. Thank you for emptying the dishwasher all those times even though we both know it's my job.

Thanks to Thomas Blader for his detailed tech editing. Having done some tech editing in the past, I know what a tough job it can be. Thanks to Sara Shlaer and Jenny Watson at Wiley for being the most patient cat-herders out there. Special thanks to Wayne Tucker and Jesse Keating for all the knowledge they've shared with me during and ...

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
