We now invite proposals for developer rooms. FOSDEM offers open source and free software developers a place to meet, share ideas and collaborate. Renowned for being highly developer-oriented, the event brings together some 8000+ geeks from all over the world. The tweny-first edition will take place Saturday 6th and Sunday 7th February 2021, online. Developer rooms are assigned to self-organising groups to work together on open source and free software projects, to discuss topics relevant to a broader subset of the community, etc. Most content should take the form of presentations. Proposals involving collaboration across project or domain boundaries are strongly encouraged. For obvious reasons we will unfortunately not be able to run a live conference this year, but we still want to give communities a place to meet online. We are working on a an online platform (streaming + chat) allowing devroom organizers to run the conference with prerecorded talks with live qa and live presentations with streaming and archiving. The recordings will be published under the same licence as all FOSDEM content (CC-BY) Developer room proposals should be submitted through the form at https://fosdem.org/devroom which contains further information. Questions or remarks? Contact us at devrooms@fosdem.org. Key dates: 31 October - deadline for developer room proposals 10 November - accepted developer rooms announced 15 November (or earlier) - developer rooms issue Calls for Participation 31 December (or earlier) - developer rooms publish complete schedules Note that the demand for devrooms may exceed the supply (even for an online event). By applying for a devroom you are making a commitment to fill the schedule. Devroom coordinators must enter a complete schedule into our conference system by 31st December. It is particularly important to be available and to respond promptly to emails about the schedule for about a week either side of this date. As we also run this event online for the first time, we would like to get your input on what duration would be good for a devroom: one whole day, or rather two afternoon sessions? Please indicate whether you would prefer Saturday, Sunday or both days. Please let us know what according to you would be an interesting timespan for your devroom: eg one long slot on Saturday or rather two shorter slots on Sunday.
