Creating and releasing an application

I love sim racing, so I thought it would be an interesting exercise to create an application that makes use of Assetto Corsa Competizione (ACC) telemetry.

The basic operation is this:

The client sends a registration message to ACC
ACC replies and starts sending telemetry messages

This is all done over UDP.

ACC messages

The first step was to create a library that could parse the message byte streams. There is a little bit of documentation in the way of some C# code and a ServerAdminHandbook.pdf that can be found in the ACC installation.

Clean architecture - part 1

After porting my template app over to Kotlin, I thought it was time to attempt rewriting from a layered architecture to a ports and adapters/hexagonal architecture.

In the layered version, the usual patterns exist:

The domain models ARE the database entities
- The domain model is compromised, cluttered with persistence concerns and far from clean
Services implement the business logic, manipulating the domain (database entities) and persisting them via the repositories
- Unfortunately the services usually end up being classes with a bunch of methods
