Summary

In DDD, the "ubiquitous language" is central, but it's richness and fluency is hard to render in the object-oriented medium. Domain-specific languages hold out the prospect of to express models and application logic in far better suited language. In this presentation, Eric Evans talks about how DDD and DSLs works together in complex business applications.

    Eric Evans does not seem like great presenter, like his previous presentation on DDD, this too can put you to sleep.

    But if you stay awake - he is saying something very important.

    Eric is not a presenter, he is a good thinker about software development. His ideas are very exciting and I enjoy listen to them.

    I completely disagree with comments about Evans being a mediocre presenter.



    I thought this was a great discussion of the current state of DSLs within the context of DDD. All I want from a presentation is digestible interesting content, and Evans does this very well.



    Yes, if you have no interest in these topics, Evans's style is not charismatic enough to compel your attention, but if you actually care about these ideas, he's a wonderfully thoughtful speaker.

    I have to say I agree with Al on this one. I recently read Evans' book so was keen to watch this to the end.



    I would have liked some discussion on language features and their support for DSLs (closures, type looseness, mixins, etc) and the risks that using these features might create in furthering abstractive qualities - I wonder if what he's saying is effectively what Paul Graham said, but from a different angle - i.e. we should all be busy learning Lisp...



    That aside, except for some strange camera issues with contrast, I enjoyed this.
