Before the event

Call for Participation / call for papers

Devrooms issue a Call for Papers.

We can also make adjustments to the names of devrooms at this early stage - particularly if related proposals got combined or you want to emphasise some little change of focus.

Full details of all talks and speakers that you schedule must be submitted into our ‘pentabarf’ database which is used to generate our website no later then 15th December. Please try to complete this earlier. It is better to find out scheduling conflicts early, and by the end of december it is hard to reach people. The schedule at the 1st of January is used for the booklet.

All submissions must go through:

Remind speakers that if they already have an account from a previous year they should reuse it. (Our website links speakers to all their talks across all the years of FOSDEM.) Then you can use the system to review and select talks, and transfer them between devrooms if appropriate.

Reviewing talks

Use this to view and review proposals assigned to your devroom track. You can add ratings and remarks in the Rating tab. These will not be accessible to the speaker.

Use these fields for your workflow:

Ultimately, all ‘events’ in your devroom track either need to be rejected, or accepted and (re)confirmed. Obviously, don’t change the state of events in other tracks.

Please don’t change the tracks assigned to any Main Track / Keynote / Lightning Talks at this stage as we have not reviewed them yet and it’s only fair that we consider them under the track that the submitter selected before considering transferring them to a different track.

(And we won’t object if any of you help us out by adding your own review comments or scores to events in these tracks as long as you are being reasonably objective and not just giving your friends’ talks top scores!)

Website schedule

The website is generated from the data in pentabarf. This runs automatically every few minutes.

You can see when it was last updated near the bottom of the events page.

Note that the data gets pulled from the database slightly before this timestamp is generated - sometimes a few minutes before. If nothing on this page changed, the date won’t be updated. shows the last modified date for every page on the site.

If the system detects an inconsistency in the data, it stops updating the site until this is corrected in the database.


Pentabarf still does not detect if a speaker has been allocated two slots that overlap so do watch out for that!
