Acknowledgments

I’d like to thank Grace Buechlein for getting the ball rolling, and David Barnhart for everything he’s done to help make my life easier during the writing of this book (including introducing me to some cool new music!).

Special thanks to Development Editor Sean Dixon for his valuable guidance and direction for this book, and to Dr. Don Argo for his insight into the inner workings of how computers think—even if he’s not aware that he provided such insight. Thanks, Don!

Most importantly, uncounted thanks to my lovely Carleen for her diligent proofreading and critique sessions, and for making sure that I remembered to eat and sleep occasionally while writing the manuscript and source code for this book. (You’re the best, Imzadi!)

Julian F.

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.
