The Code Generation 2008 in Cambridge (UK) has been real fun. Karsten, Sven, Peter and me, we have met a lot of interesting people from the model-driven / DSL world, and have heard lots of interesting views and news on code generation.
The best thing in a conference on code generation is that the participants are already convinced of the benefits of modeling, so you don't have to explain every time from the very beginning why you think modeling is a good thing.
Last but not least, our workshop on openArchitectureWare was very successful and we has been rated top by the participants. It feels good to be assured that we are working on the right things.
