Last week I spent at UML & Design World . I did several sessions.
Monday: I co-led a tutorial with Jack Greenfield on Software Factories.
Tuesday: I led an in-depth class and demonstration on Building Domain Specific Languages for Visual Studio.
Overall the reaction at the conference to our work was extremely positive. There was a lot of interest in DSLs and in software factories, especially the pragmatic aspects of how they deal with actual development activities such as writing code.
