In the past we used to run Jenkins. The build server always had weird issues and was a pain to maintain. Travis is a great solution for CI. Their Debug build features makes it trivial to figure out why your build broke. The integration with Github is also very slick. One thing they could improve is the documentation on the .travis.yaml format. All in all, great company and very responsive supports. Over here at getstream.io we're a fan. Keep up the good work guys!

Go has been a joy to work with. Performance is often 30x of what we used to see with Python. It's a performant and productive programming language: https://getstream.io/blog/switched-python-go/
