The list of accepted "dev rooms" for the FOSDEM
2013 conference have been announced.
The FOSDEM 2013 development rooms are listed here
and range from X.Org to PHP and BSD and NoSQL. FOSDEM is happening on the 2nd and 3rd of February in Brussels.
With there being a one-day X.Org developers' room again, I'll certainly be back out in Brussels for the event. The Free Open-source Developers' European Meeting is easily one of the best Linux/open-source events still in existence and is always filled with lots of interesting and technical talks.
