Really not disappointed by this week spent at #newcrafts. Meetings, reunions 🫶, lots of fascinating discussions in the hallways about everyone's problems, and some truly interesting sessions (more to come).

#KanDDDinsky Berlin is the only tech and DDD conference with a rock n roll mindset.
During my stay, I was able to borrow for free and to play on an acoustic Gibson G-45 🤘.
Thanks to @heimeshoff.bsky.social and all the crew for that. 🫶

Explicit vs Implicit coupling.
We need to be aware when we introduce a new coupling between 2 overlapping decision models (in DCB).

If we can query for some events, we can define dynamic consistency boundaries (DCB) at runtime.
Labels/tags « Product » and « Cart » here for instance.
+ Conditioning append with optimistic locking

Un peu déçu par le Caprice des Dieux in carrozza dont tout le monde parle en ce moment. Le coté réconfortant du fromage fondu n’est pas suivi de goût et l’ensemble manque de caractère. Dommage, j’étais hypé par le concept et ce contre-pied.
