The JetBrains team had a wonderful time at Devoxx 2008 in Antwerp, Belgium – from the many interesting presentations, to the huge number of attendees, to the fantastic entertainment – everything was just perfect! Special thanks to Stephan Janssen and the other Devoxx organizers for, once again, putting on such a great event. If you were there, chances are you stopped by our booth – to demo IntelliJ IDEA 8.0 and TeamCity 4.0 – and entered to win a free IntelliJ IDEA license.

The Greatful Dead said it best: What a long, strange trip it’s been. Our wonderful trip to Cologne was topped off with a crazy adventure home. After being stuck in a traffic jam on our way back to Amsterdam’s airport, ditching our GPS’ suggested route, and making our flight with only seconds to spare, we thought we were home free. How wrong we were. One hour and three drinks later, the flight crew informed us of a potential engine problem. Luckily for us we were still on the ground :-). Another hour passed before we learned the potential problem was a real fuel leak and that the air

The JetBrains-Ajaxian Joint 2006 Survey is now officially closed. We'd like to thank the over 600 developers who participated in the survey. The results will make a difference in the way JetBrains will approach AJAX support. As a little carrot to encourage participation, we gave away 10 free personal licenses for IntelliJ IDEA 5.1 to randomly selected survey participants. The winners list appears on our website at http://www.jetbrains.com/idea/quest_intro.html. Thanks again to all who participated in the survey, and stay tuned for cool new AJAX features in IntelliJ IDEA!

For those who missed our presentations at The AJAX Experience and JavaOne 2006 Conferences, we have published a short report on the JetBrains web site. There you can view some photos, check the Google video recordings of both presentations, as well as download a PDF copy of the AJAX with Pleasure brochure that we were giving away at the show.
