Never ever update an event. But why?

Home



I heard and read a lot about Event Sourcing (ES) but earlier I hadn't had occasion to use it in the real-life system. This year I got this opportunity :) For many years I was working with traditional architectures so ES + CQRS + DDD is like a new world to me. Very refreshing experience! I've already learned a lot but I'm still learning and discovering new things. For example, not so long ago the versioning of events was "mysterious" for me.

.NET Developer Days 2017 - Grand finale

Home



It's time to make the summary of .NET Developer Days 2017. Let's start with the organisation aspects. Here I'll shortly say it was simply good and I cannot complain. The good example showing that organisers really try to make everything ok is a fact that a friend of mine was able to register for the conference just one day before the event (what theoretically was not possible). Now let's move to the presentations. Here I have much more to write.

How did my presentation go?

Home



Two weeks ago I gave the presentation about artificial intelligences that write programs. Now, I got results of the survey conducted after the presentation and I decided to share some data with you. Below you can see the summary. The participants could judge me in 4 categories and 14 of them decided to do that. (Thank you!). I think that there were around 30+ people in total in the room.
