Learn how GitHub’s globally distributed teams use GitHub tooling to develop and design GitHub, collaborate with engineering, sales, marketing and legal and deploy more than 500 times a week. Experience ChatOps, feature toggles and refactoring in production based on life demos and real examples. Agenda: * Zen of GitHub as guiding philosophy for any new feature work, nature of features, internal and external communication * remote nature of GitHub organization and its implications on standups, pair programming and working style (default to asynchronous) * walk through the GitHub Flow based on examples from different teams (engineering, web site, legal, services, solution engineering) * introduction of GitHub’s deployment API and life demo how to use it from Slack and Hubot * introduction into ChatOps * ChatOps examples from the DevOps team * ChatOps in the context of continuous deployment at GitHub * introduction to the confidence dashboard (deployment metrics) * introduction to Haystack (exception monitor) * Feature Toggles @ GitHub (based on flipper) * Refactoring in production @ GitHub (based on scientist) * Q & A

The Zen of GitHub

• Responsive is better than fast
• It’s not fully shipped until it’s fast
• Anything added dilutes everything else
• Practicality beats purity
• Approachable is better than simple
• Mind your words, they are important
• Speak like a human
• Half measures are as bad as nothing at all
• Encourage flow
• Non-blocking is better than blocking
• Favor focus over features
• Avoid administrative distraction
• Design for failure
• Keep it logically awesome
