On January 17-18, I'll be in Germany to attend DrupalCamp Köln (aka DrupalCamp Cologne) and hang out with the German Drupal community. DrupalCamp Köln is organized by Thomas Narres, Daniel Niehaus, Jürgen Brocke, Torsten Zenk, Florian Latzel, and others in the Köln/Bonn users group.
With so many good presentation proposals, it's hard to point out just a few. An incomplete list of sessions include SEO, fields in core, Acquia, SimpleTest, Ubercart, performance optimization, installation profiles, Solr, module writing, theming and many more.
This is the first ever Drupal-specific camp (or Drupal un-conference) that Germany has ever seen, and so far a little more than 150 people have signed up. The organizers are expecting to max out the venue with around 180 participants. Prominent German Drupalistas attending and/or presenting include: Konstantin Käfer, Hagen Graf, Daniel Juling, Ben Birkenhagen, Gerhard Killesreiter, and plenty of other great contributors. International Drupalistas coming include: Morten (King of Denmark), Mikkel Høgh (Denmark), Florian Loretan (USA / Switzerland), Roel Demeester (Belgium), Jo Wouters (Belgium), Damien Tournoud (France), Joeri Poesen (Belgium), and many more.
Three people from Acquia will be present; Robert Douglass, Jeffrey McGuire (aka Jam) and myself. I'll do a keynote on Drupal. Robert plans to demonstrate the latest ApacheSolr improvements and will give a first glance at Acquia's hosted search solution. Robert and I will also be holding an Acquia Q&A session, and Jam will be ready to help with your Drupal 5 to Drupal 6 upgrade problems, pesky Views 1 to Views 2 conversions and hosting a moderated discussion on Upgrade as a Barrier, and how to move adoption forward.
Two other things you shouldn't miss are the Drupal.org upgrade and redesign hackathon — your chance to get your hands dirty with the big Drupal.org redesign project — and the Ubercart workshop that takes place on January 19 and 20, right after Drupalcamp Köln. The Ubercart workshop is organized by Commerce Guys and AF83.
