MariaDB at FOSDEM 2021

Today FOSDEM has started! Attend the live sessions happening in the MariaDB devroom (10-18 CET) – and chat about the sessions. Visit the MariaDB Stand (9:30-18) with its own chatroom. And take our poll. Note! We have video issues with the live Q&A – hope it will be fixed through FOSDEM later today. Arranging a meeting for 8000 developers is hard, and attending it can be bewildering – also online.

More notes: How To FOSDEM 2021.

Around this time each year, thousands of free and open source developers gather in Brussels for FOSDEM. The first FOSDEM, standing for Free and Open Source Developers European Meeting, was held back in 2001 (there was an OSDEM in 2000) and since then its grown to be rightly famous, an institution, a conference not organised by any vendor or focused on a particular developer community; instead a team of volunteers helps organise the event each year, and each devroom in turn has its own team.

Space is at a premium, the Université Libre de Bruxelles venue gets as crowded as a sports stadium during a final. MariaDB has attended in the past, and in previous years shared a presence as part of the MySQL, MariaDB and Friends devroom.

This year of course FOSDEM is going virtual, and with space no longer a constraint, MariaDB has the opportunity to enjoy its own dedicated devroom.

But not just a single devroom. There’ll be MariaDB-related talks in a number of other devrooms as well, and you’ll also be able to meet some of the MariaDB Foundation team at the MariaDB stand.

FOSDEM is so huge, that navigating can be tricky, so this post aims to be a one-stop location for finding everything MariaDB-related at FOSDEM 2021.

We look forward to seeing you!

MariaDB Stand

The MariaDB Stand will be open throughout FOSDEM. View short videos on what we do, or come say hi and meet someone from the MariaDB Foundation. We’ll be happy to discuss anything MariaDB-related, or try answer your questions. Suggest a name for the MariaDB sea lion, or tell us what you think MariaDB should be focusing on.
