How to effectively observe the runtime behaviour of your core domain

Logging statements have no place in the domain. There are multiple better alternatives you should use instead!

What makes an event sourced domain?

In an effort to generalize event sourcing to the whole domain I try to adapt concepts previously developed for aggregates to other domain objects such as services, process managers, sagas and repositories.

Can I map one command to multiple events?

Since it would be beneficial for commands to be able to issue multiple events reflecting its behaviour I modified an earlier approach to event sourced aggregates to allow this use-case.

Accessing the filesystem with an asp.net core app run on Docker

I ran a bunch of experiments to figure out how to access the filesystem from a .NET app running on Docker.

What is Event Sourcing?

This post attempts to explain event sourcing through examples showing what it is and what it is not, while highlighting some of the strengths and reasons for using it.

More transparent command to event transformation

An improvement upon the previously proposed event sourced aggregate where command provides type information about its returned domain events.

Creating event sourced aggregates with C#

The aggregate is a well understood concept within DDD practices. The addition of event sourcing to the mix might however complicate things, and the once pretty domain is now in shambles. In this post I'll cover the addition of ES, while keeping the awesomeness of DDD in place.

An algorithm for interpolating or extrapolating two lists

Having my brain eat itself while trying to interpolate two data sets to one another I came up with this working, though overly complicated solution. It works, but can be implemented in a much less convoluted mess.

Coarse commands emitting granular events

In order to allow an event sourced software system to evolve I believe it to be important to issue coarse commands emitting granular events. In this post I explain why.

Rolling back migrations to a previous version of Entity Framework Core

I discovered there was a dependency incompatibility between EF Core 5 and SqlKata. I weighted my options, and decided it would be easier to revert back to EF Core 3, than to solve this dependency compatibility issue in another way.
