Great introduction in Event Sourcing, Domain Driven Design and CQRS. For people new to this concepts it might have been a little overwhelming (too much new things). But I think the talk was a perfect match with the audience. Willem-Jan knows what he's talking about.
A very interesting good talk. Clear introduction to event sourcing and CQRS and why you want to use it. Sometimes you could get lost a bit in the code if you were not watching close enough, perhaps you can turn it into a live coding?
Great talk, however, I think the talk would have been more fluid in English
As a Broadway user the talk was easy to follow and all concepts where very clear to me. For newcomers these topics can be quite hard to follow, but I think that's a problem which can't be solved in a one hour presentation ;-)
As a matter of fact you did a great job fitting all these topics into a hour time slot. You also proofed you can handle some technical issues during the talk.
It was nice to meet you in person and hope to see you again on a future BredaPHP meetup!
