Event Sourcing tests double as documentation. Given: [OrderPlaced, ItemAdded] When: RemoveItem Then: [ItemRemoved] This reads like a spec. It IS a spec. Your tests become the living documentation of your business rules.

I’m reading simultaneously @htmx.org book on hypermedia and recent @danabra.mov articles on React Components. I highly recommend that, as it gives a lot food for thoughts. Good design exercise to think about the pieces those concepts overlap and how they differ.

The pendulum swung back! Now, the "modular monolith first" is the best advice. But is it? It sounds great in theory but can fall short in practice. In practice, too often: module boundaries erode, resource isolation is absent, and that promised "easy split" rarely happens. 1/

Fellow #DDD folks out there, Can someone explain to me what is a _practical_ difference between a vertical slice and a bounded context?

Let’s say it’s Friday. Not party Friday, Black Friday. You’re working on busy e-commerce system that handles thousands of orders per minute. Suddenly, the service responsible for billing processing crashes. Until it recovers, new orders are piling up. How do you resume processing after restart? 1/

🚀🧑‍🔬 Next big announcement in #Emmett. It just got the first version of the #SQLite event store, thanks to the great work by @dav-d.bsky.social! It's early, so it may have some rough edges, but it works, and you can play with it! See release notes! github.com/event-driven... Fun times!

My thoughts after reading some of the recent discussions.

I love copying code. I hate copying knowledge and responsibilities.
