FOSDEM is a two-day event organised by volunteers to promote the widespread use of free and open source software.
Usually taking place in the beautiful city of Brussels (Belgium), FOSDEM is widely recognised as the best such conference in Europe.
What is FOSDEM?
FOSDEM is a free and non-commercial event organised 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 world;
- be informed about the latest developments in the open source world;
- attend interesting talks and presentations on various topics by project leaders and committers;
- to promote the development and benefits of free software and open source solutions.
Participation and attendance is totally free, though the organisers gratefully accept donations and sponsorship.
Developer rooms
The FOSDEM team feels it is very important for free and open source software developers around the world to be able to meet in “real life”.
To this end, we have set up developer rooms (devrooms) with network/internet connectivity and projectors where teams can meet and showcase their projects. Devrooms are a place for teams to discuss, hack and publicly present latest directions, lightning talks, news and discussions. We believe developers can benefit a lot from these meetings.

The Russian Woodpecker over the horizon radar, a blast from the past – Keith KI6BDR.
Hidden deep in a serene forest yet taller than the clouds, standing in surreal beauty is an antenna array like none other on earth, having an aperture area greater than 15 U.S. football fields. One of the great wonders of the world – a top secret Soviet radar, so secret that even the name is uncertain, for it had many. It was the Russian Woodpecker. It was the Steel Yard. It was Duga.
The story of this top secret place is one of mystery and intrigue. Now abandoned, a rusting testament to man’s cold war hubris, almost all popular accounts on the web are seriously flawed – victims of deliberate disinformation. Where did it come from? What did it do? Did it transmit? Did it receive? Was it the first of three, or the third of two?
Keith Snyder, KI6BDR, has been busy reverse engineering to uncover truth before time erases history. Keith shows visible engineering clues that reveal the mission and correct the history of the huge “Duga 3” antenna Array. The Duga 3 is located a few kilometers from the Chernobyl nuclear power plant site. Although it has fallen into disrepair, it stands today due only to a hasty exit forced by radiation from the
Chernobyl nuclear accident. The nuclear accident ironically protected the array from dismantlement, a reprieve from all but the ravages of time. The antenna array today attracts tourists who visit Chernobyl. It is one of the 8th wonders of the world due to its Titanic size.
