Come join us on March 17th!

Love creating stuff on your computer and LOVE baseball? Come hack with us on March 17 at mHub, 965 West Chicago Avenue.

Baseball Hack Day is an annual on-site, in-person hacking event where area baseball fans come together and create baseball-related projects to compete in a fun, friendly, one-day competition.

Born in Boston spring of 2012, Baseball Hack Day is a grass-roots, open-sourced movement, held at the same day at different locations all around the world. The goal of the day is to bring creative tech minds into one room, and see what they can produce within a limited time. The project could be (but is not limited to) a tool, simple web app, mobile app, web site, data visualization, or a video.

This event is based on the principal of the original the Hack Day Manifesto and will always be free to attend, thanks to our generous sponsors. We are run by volunteers, pro bono, labor for love, and we’ll never be for-profit. We follow contributor-covenant-style code of conduct.

New to hack days? Have no fear. This is a hackathon of developers and designers of all levels. See past submissions to get an idea. See our resources in github wiki, check out our inspiraton blog on tumblr, and follow us on Twitter @BaseballHackChi.

Guidelines & Rules

First and foremost, this event will be a success if everyone has a good time. That is why we have a Code of Conduct. All attendees, sponsors, partners, volunteers and staff at our hackathon are required to agree with it. We want a safe, fair and fun environment for everybody.

We are using a hack submission service called DevPost. In order to win, you need to submit the hacks through it. It helps organizers keep track of the teams and the projects they create.

Hacks could be (but are not limited to) a tool, application, software, website, or data visualization and may be built using any programming language and platform that you choose. Teams can be of any size, but awards are only given to up to four individuals. Hacks will be judged for 1) Creativity/Originality, 2) Design/Presentation, and 3) Execution/Functionality.

The majority of your coding must happen during the event. Some work done prior to the event is allowed, but it should be disclosed at your demo. Ideas that are compact and executable in one-day format are encouraged, and we will reward teams that recognize this time constraint.

When time is up, you will have short show-and-tell and demo time (3 to 5 minutes, depending on how many projects there are). Judges also will come around during the event and you are encouraged to tell them about your projects at that time.

Prototypes/mockups for demo are OK, but working websites or mobile apps are strongly encouraged.
