Last week, I had the pleasure of attending a development meeting in Stuttgart, Germany organized by the folks I work for. It really had the atmosphere of a small DrupalCon or similar FOSS conference -- a lot of intense thinking and discussion, but a lot of fun and really cool stuff at the same time.
Since some of the stuff we worked on is not ready for public consumption (though most will actually be contributed to the open source community eventually), I'll not write about it now.
