Hackathons

For many years OpenBSD developers have been holding hackathons -- events where pure development happens. Hackathons do not have talks, or a specific schedule. The event space and accomodation is funded out of project money, but most developers pay for their own travel. People will arrive at a hackathon to work for a straight stretch of time on the projects they wish to, in the same room as the people who they need to talk to about their ideas. Hackathons are about writing code.

Since people from many different timezones are in the same room, development is almost around the clock. Developers sometimes joke about returning home without jet-lag.

Hackathons attendees come by invitation only. Some new people who show promise are sometimes invited to see if they have what it takes. Hackathons are not developer training events.

Recently OpenBSD has been experimenting with the idea of holding more mini-hackathons. These events are limited to a maximum of 16 people and 4 days and focus on only one or two aspects of the system.

Here are some details about past and future events, also showing a part of the artwork from the event T-shirt (if there was one made). The shirts are only given to people who attend the event, and they are worn with pride. Every shirt contains at least one developer in-joke, so don't worry if you can't understand the shirt. Just enjoy them.
