What if the spec, not the prompt, became the source of truth?

Barbarische, primitive Kriegsminister barbarischer Staaten tun barbarische Dinge und traumatisierten damit ihre eigenen Soldaten und die Bevölkerung, während ein barbarischer Präsident sich selber vor dem Spiegel bewundert.
Ja, definitiv kann man noch tiefer fallen. #USA

I use it for E2E tests since they released the first version! I also use the MCP for my AI agent.

Did your coding agent's change actually reach the running app?

The Dev Loop CLI in Vaadin 25.3 (preview) tells it: whether the app is running, hot-swap or restart, and whether each change is live.

That's because it belongs to the database session and the statement is sent to the database. In case of a cursor you'll get back a handle to the cursor.

I’m overwhelmed by the number of people planning to attend my deep dive tomorrow at @devoxx.com 😀
See you all in Antwerp 🇧🇪

My advice has been don't use AI to scaffold a new Spring Boot project because you get outdated version. Today I did that in a demo, and guess what, Opus 5.5 uses the Spring Initializer 🤯 That model is awesome! Luckily switching to Sonnet 4.6 helped and it created a Spring Boot 3.3.4 project 😅

In the 90s I wrote COBOL on the IBM mainframe and had all the roles: customer talks, architecture, code, production.

With AI, we are back. But now the spec is the input for the AI.
