This month we're going to work on open source.
DigitalOcean, GitHub, and Twilio are sponsoring a program to send you a free tshirt if you submit 5 pull requests to open source projects in the month of October. Sign up here: https://hacktoberfest.digitalocean.com
Bring a laptop and we'll help you find a project to contribute to.
Afterwards, we go out for drinks and dinner at the nearby HopCat brewery.
