The Austrian Computer Society holds a one-afternoon presentation on Open source web development frameworks on November 29 here in Vienna, Austria.
All presentations will be in German (but the presentation slides will probably be available in English).
Participation is free (registration is required!). I’ll do a talk on Ruby on Rails which will “compete” with some Java-based frameworks (Cocoon/JSF/Struts). Hopefully I can lure some Java developers to RailsTweet
