GitHub Engineering

Cross-platform UI in GitHub Desktop

The comparison graph is the centerpiece of GitHub Desktop. It both drives the interaction with your branch and shows you the effects of your changes relative to a base branch.

Benchmarking GitHub Enterprise

The release of GitHub Enterprise 2.0 brought more than just new features and support for deployment on Amazon Web Services. It also included a rework of our virtual machine architecture to improve performance and reliability. In making these changes, we used straightforward benchmarking each step of the way. With this data and our trusty set of Unix tools, we were able to discover, debug, and eventually solve several interesting performance issues for our Enterprise customers.

Scripts to Rule Them All

At GitHub we have a lot of software running our product and company. We also have a lot of potential contributing members. Being able to get from git clone to an up-and-running project in a development environment is imperative for fast, reliable contributions. A consistent bootstrapping experience across all our projects reduces friction and encourages contribution.

Exception Monitoring and Response

Like most software applications, GitHub can generate a few exceptions. Incoming exceptions range from system-level issues including Git timeouts and missing references, to application-level issues including simple code mistakes and JavaScript errors.

Brubeck, a statsd-compatible metrics aggregator

One of the key points of GitHub’s engineering culture —and I believe, of any good engineering culture— is our obsession with aggressively measuring everything.
