The biggest risk of vibe-coding is unintentional vibe-modelling
The model is software's heart, bringing value to users and ensuring it will last over time. A well-crafted model is challenged against business expertise, not merely the result of a set of specifications

And now at @breizhcamp.org : Hafsa El Maizi from @shodo.io, about CI/CD pipelines concepts
I can already related with the "as a developer, I noticed that CI/CD pipelines are often obscure for devs" introduction — (sadly) heard/saw that so many times recently

Writing code isn’t just machine instructions; it’s modeling a domain. George Box's insight: "All models are wrong, but some are useful", reminds us models simplify, not eliminate complexity.
But when do models stop being useful or become harmful?
Over time, models face tensions like: 👇

Just a reminder: Domain-Driven Design (DDD) is NOT a tool.
Too often, people reduce it to "a way of writing code" and compare it to CQRS, Event Sourcing, or Clean Architecture.

💥 Struggling with microservices complexity?
Whether it's Distributed Monoliths or tangled monoliths, unclear boundaries are often the root cause.
Let's discover Model Mitosis, an iterative way to clearly define boundaries without premature splitting at Explore DDD, Wed 5:15 pm in room Crystal B&C!
