I want to tell you about 2 upcoming events: fosdem and HAR2009.
Fosdem is according to their website a free and non-commercial event organized by the community, for the community. Its goal is to provide Free and Open Source developers a place to meet. (http://www.fosdem.org/2009/). Fosdem will take place the 7th and 8th of February 2009 in Brussels. There are every year people comming from all over the world. One of the things I like is the open idea. If you want to talk to somebody and exchange ideas, you just walk up to that person and start a conversation. If you go back to the previous years you'll see that they managed to get some important speakers in the open source community.
HAR is totally something else. HAR's website is http://har2009.org/. It is an international technology & security conference. It will take place in August 2009 from the 13th till 16th near Vierhouten, NL. It is something like Rock Wechter but for people who are into technology and security.
I plan to go to fosdem to a couple of talks and I would like to go to HAR if it is possible.
