Open Source Bridge is an annual conference focused on building open source community and citizenship through four days of technical talks, hacking sessions, and collaboration opportunities. Participants include developers, hardware hackers, community organizers, and people involved in the business of open source.
This year’s event will take place 24-27 June 2014 in Portland, Oregon, USA. It is 100% volunteer run, and they are also looking for volunteers to help. The agenda is created by the community by ranking/evaluating proposed talks on their web site.
I have attended previously, so if you have any questions about the event, feel free to ask here.
