Kore Nordmann has a new post to his blog mentioning that the Call for Papers for this year's Free and Open Source Conference (FrOSCon) has been started up.

This year we will organize a PHP room for the third time, like in 2006 and 2007. We hope that we can keep up with the amazing conferences from the last years, and we expect it to be a wonderful open source event again. We would love to welcome you in the PHP room, either giving a talk, or just for a chat or listening. We are looking for speakers right now by starting the Call for Papers (CfP), which will end at the 23.05.2009 - please submit your talks.

Other non-PHP topics you could also submit on include development practices, security, desktop development, open hardware and several Java-related suggestions. You can find out more about these and what needs to be done to submit your proposal on this page of the conference site.
