FOSDEM is a huge grassroots Free and Open Source Software conference held annually in Brussels, Belgium. It brings together thousands of users and developers from Europe and around the world. The conference is organized into themed tracks called "developer rooms" or "devrooms".
For the first time (I think) there will be a devroom at FOSDEM 2025 devoted to Open Source software that implements ActivityPub or is otherwise closely related to the Fediverse.
Interested software developers are invited to submit proposals for talks at the event. It would be especially great to have talks about Lemmy or from the wider Lemmy ecosystem, since this is such an important part of the Fediverse developer community.
Instructions for submitting a proposal are in the linked blog post. Please let me know if you have any questions!
