two weeks ago I’ve got hold of a /mobile thing/ and I must admit that it is nice / funny / interesting / connective ( and sometimes not :-/ — it does not correctly sync contacts and calendar entries with my mac … but beside that ) … and I like it!

While driving through Austria we got blocked by …
Well – at least some them have recognized our intent – otherwise I would not have been able to write this.

I have submitted my project GenGMF as new project proposal to the Eclipse foundation.
Now I would like you to discuss the proposal in the GMF forum (prefixed with “[GenGMF]” in the subject). If you want to get named on the list of interested parties please comment this post. … and If you like the project you are welcome to spread the word.

If all people would live on earth as much as the Germans, we would need the resources of three planets.
Said in the German broadcast Monitor (07.01.2010).
Germans take much resources — and there are other countries “outperforming” us. Nevertheless every well situated people have to make at least one short step towards a sustainable life.

Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.

Alexander found a BBC news about how bad skilled programmers can cause global warming. Obviously we need a global warming bug tracker!

After the Eclipse DemoCamp in Leipzig a few days ago I went to the Berlin DemoCamp and presented emf.observables a second time. “Prezing” is fun! But step by step…
We arrived just early enough to get one seat of around 60 seats and see Ralph Müller with his key note. He incited us to become a Eclipse Foundation member and to visit the Eclipse Summit Europe 2010. He hadn’t any free tickets… 🙁
Kristian Duske showed us a really cool use case for GEF3D. He used it to work with GMF mapping models (which can get really complex) in a very intuitive way. This is completly different way of handling GMF complexity in comparison to GenGMF.
Nothing is impossible! Arc lines between connections in a GMF based editor have been implemented! For a variability editor it is an essential feature and I know from my diploma thesis that such features are really hard to achieve with GMF.
Xtext is a project presented since the early days of Eclipse DemoCamps and this time done by Peter Friese. There are some new features on the roadmap for the next 0.8 release.
Break: During the breaks we talked about what we have seen and raided the delicious buffet.
Despite the original order we’ve got the one and only double feature now — two presenters using two beamers. Joachim Hänsel and Jaroslav Svacina made us aware of EVOTest a framework for evolutionary testing. It uses optimization search algorithms for finding problematic input parameter.
(The second beamer was too dark for the picture.)
Do I have created a good model? How does it conform to the guidelines? Answers to such queries can give Metrino which has been presented by Marcus Engelhardt. There is also an adapter for the EMF validation framework so you could see the results in the problems view.
Matthias Köster created an IDE for Clojure and used the DLTK to do that. He showed us how easy it is to get fast results with the DLTK.
Break: Do I have said already that the food was delicious? Thanks to Tom for organizing the DemoCamp!
Stephan Herrmann showed ObjectTeams and a adapted version of EclipseLink to persist next to the objects the associated teams and roles.
I’m sorry, the is no picture available
SMILA is system for extracting semantic information from arbitrary media. It e.g. extracts images from PDF files and makes them searchable. You can also search for similar images like with google! Presented by Igor Novakovic.
Now it was my turn to present emf.observables. It is my last project and generates IObservable wrapper classes for EMF model classes. The wrappers provide an easy and type save access to the EMFObservables hierarchies.
I have used “prezi” instead of some slide based software and presenting it was much fun. Creating a prezi is relative easy and intuitive but the software to do that is very feature-limited.
All in all it was a very nice evening where I have seen many interesting projects and talked to many interesting people during the breaks.
Many thanks to Lars for giving me a lift to Berlin and to Martin for the short stay.

Yesterday itemis had organized an Eclipse DemoCamp in Leipzig once again. Like in the many Eclipse DemoCamps I have seen before – it was once again a happening with many interesting projects.
The planned first presenter had some technical problems with the beamer so I filled in and showed my “prezi” instead. “emf.observables” is a new project of mine and can be used to aid in the programming of RCP applications. It generates type safe wrapper classes for IObservable Objects. It was the first time that I used Prezi for my presentation and I have to admit that presenting it was fun. From the questions I had to answer and the personal chats afterwards I got the impression that it was interesting to the audience.
Alex showed a nice demo from a RCP application he uses for his voluntary work at the Deutscher Go Bund. He uses a DSL developed with Xtext for entering and validating withdrawals and their rejects for all associated members. It was interesting to see Xtext in an application without the generation of source code.
During the break we had some time to chat to each other while eating delicious Soljanka as well as potato soup.
Karsten got the beamer working and showed us how easy it is to use the Java Persistence API 2.0 reference implementation “EclipseLink” in an OSGI context. The Eclipse JPA tooling allows you to generate the complete JPA infrastructure from an existing SQL database and to administrate it. OSGI declarative services are used to wrap queries. It was quite interesting but I can’t use it in my current projects because they don’t use a database.
The FeatureMapper is a tooling to connect arbitrary existing EMF based models with features in a product line context. The existing EMF, GMF and EMFText editors are extended by the tooling and display which model objects a selected feature configuration covers. They also want to implement support for Xtext.
The DEFT (Development Environment For Tutorials) project is really interesting because it allows you to keep your documentation current as you change your code. Code snippets are copied into your documentation with code formatting. The Tuba project does the same but for models which is also very neat. They want to combine both projects and want to support screen shots from RCP applications running in a JUnit context.
I am looking forward to the next Eclipse DemoCamp in Berlin where I will talk about emf.observables too. See you there!

I can’t ressist to attend on a new Eclipse Stammtisch on Modelling which will take place in Berlin on the 19th August as mentioned by Ed. If you are interested in Modelling or not – it will be a happening and you are welcome to mark your attendance (preferably “Yes”) and get a eclipse-foundation driven beer (or other drinks as you like) for free as promised by Ralph. See you there…
