About the Author

Chris Dawson comes from a family of public school teachers. From an early age, computers provided an always fascinating and often frustrating complement to learning and teaching for Chris. Notably inconspicuous at several notable startups and technology companies like Apple, Virage and RealNetworks, Chris gratefully had the opportunity to live on three continents and experience the power and dynamism of diverse communities. As such, it is with great relish that Chris has been participating in and documenting one of the most exciting learning communities of the 21st century: GitHub.

Ben Straub is a lifelong developer, and enthusiast of the craft of making great software. He's written software for over 15 years, has authored several books, and has recorded educational software training videos. He enjoys reading, taking his kids on bike rides, chocolate, dogs, those little notebooks you carry around with you, photography, a good weekend hack, traveling, writing, food, craftsmanship, a great pen, Markdown, music, movies, and talking to amazing people.
