Kotlin DevRoom @ FOSDEM 2023


The DevRoom

The Kotlin DevRoom is a co-located conference-within-a-conference that gives us the opportunity to come together and chat, hack, and share stories about Kotlin usage in the FLOSS ecosystems.

The DevRoom will take place on Saturday 4th of February 2023, at ULB (Campus Solbosch) in Brussels, Belgium.

Join us to enjoy a full day of talks, demos, and interesting discussions about Kotlin!


From: https://fosdem.org/2023/about/ FOSDEM is a free and non-commercial event organized by the community, for the community.

The goal is to provide free and open source software developers and communities a place to meet to:

  • get in touch with other developers and projects
  • be informed about the latest developments in the free software and open source world
  • attend interesting talks and presentations on various topics by project leaders and committers
  • promote the development and benefits of free software and open source solutions

Participation and attendance is totally free, though the organizers gratefully accept donations and sponsorship.
