UXcamp Europe: wow!


That is all I can say about the awesome feedback we got after the UXcamp Europe taking place a week ago.

To give you an idea:

  • @elreiss: “UXcamp Europe in Berlin was a SMASH success. Thanks to the fab organizers for making this happen. And keep it open and dynamic!”
  • “Ranjeet Kumar came from India to #uxce10 and says it was a best conference he ever attended (other were paid).”
  • Hilko Holweg ( “Das Camp zählt zu den besten, die ich bisher besucht habe.” [The Camp is among the best I ever attended.]

During the closing session on Sunday some were suggesting to have the UXcamp take place either twice a year or make it 4 days long. Well, this might be a little too much for us to organize, but maybe there are others out there who want to do a camp themselves. We’d love to support you in that, so please speak up!

One thing we should not forget is that we only set the infrastructure for the weekend, but the participants filled it with live. Therefore, we have to thank for 57 great sessions (Saturday and Sunday). You can find many of the presentations on slideshare, where we even were a featured event! Many people helped us at either serving coffee all the time or taking care of the cloakroom, which we couldn’t have done ourselves. So, a big THANK YOU to all the 400 people who came to Adlershof to share this weekend with us.

About a third, maybe even more people were traveling a long way since they are not living in Germany. Some were even coming from different continents! We are really happy that we were able to welcome you in Berlin. In my opinion it is quite exceptional that so many people traveled that far just for a BarCamp.

When meeting people after the camp a lot are asking me: “You are doing it next year as well, don’t you?” Well, we have not yet talked about that. It is quite time consuming to organize a BarCamp for 400 people. On the other hand, I have the impression that if we won’t do it again, people might get angry with us and stop talking to us. We’ll let you know…

Developing a collaborative modeling application

In this blog post I will show you a cool application that I have worked on outside Pidoco. Some of you might be familiar with using modeling tools. For example if you are a software developer, chances are you have to design architecture diagrams from time to time. Or if you are at a big company, you might have seen one of these complicated process models that explain how your business works. If that’s the case and you use this kind of software, the Editor might make your work a lot faster and more convenient.

The Editor is a fully collaborative modeling application that lets you create technical diagrams with several people at the same time. All changes that you or others make to the diagram are automatically synced between all participants in real-time – just as you know it from the Pidoco Prototype Creator. It is written as an extension to Google Wave, a powerful new collaboration platform from Google, that helps you create all sorts of documents and artifacts with multiple people very quickly. If you did not have the chance to give Wave a try yet, let me explain how it works: You start a new Wave, an artifact which is often described as “equal parts conversation and document”. You then invite the other people to that Wave to let them participate. And with a click on a toolbar button you add our editor to the document, and start modeling. A typical use case is shown in this video. The cool thing is that you can use Wave’s powerful conversation capabilities to discuss the model while you create it.

To try out the editor yourself, visit – it is free and open source. We currently support modeling in different languages from the areas of software and process modeling, such as the Unified Modeling Language, Petri nets, Business Process Modeling Notation or Event-driven process chains. The work was done by my bachelor’s project team at Hasso Plattner Institute, the place where I study when I am not developing server components of pidoco’s Prototype Creator. Google actually liked our work so much that they invited us to demo it in a talk at Google’s biggest developer conference, Google I/O in San Francisco.
