“La gouvernance technologique, c’est l’huile du moteur de l’entreprise.”

Pour Manuel Ryan (Swissquote), les standards ne freinent pas l’innovation : ils la rendent possible.

Avec OpenRewrite, il montre comment automatiser la refactorisation du code à grande échelle.

Java 25 removes the SecurityManager, replaces ZipError, and more. Don't panic.

@openrewrite.github.io helps you get rid of the hurdles to focus on more awesome stuff - like pattern matching or concurrency.

One Maven command migrates your entire codebase safely.

Teaching @openrewrite.github.io, my favorite moment is watching devs write their first custom recipes, realize they can query any codebase like a database, then immediately plan to refactor their entire monolith.

For some reason the builders weren't working even with the latest version. Adding Lombok as dependency to the Maven compiler fixed it. We now use things like IO instead of System.out and main classes without public static. Relatively simple stuff for now which OpenRewrite did for us.

Spring Boot 4 is moving to Jackson 3 (already in M3).

👉 Check out the Jackson 3 Migration Guide: github.com/FasterXML/ja...

👉 Also useful, the OpenRewrite recipe: docs.openrewrite.org/recipes/java...

A client was about to drop $3M on new hardware for K8s. 😰

Until Kevin Brockhoff’s team wrote a custom OpenRewrite recipe + tied it into their observability platform.

Turns out the real issue wasn’t hardware at all...it was large over-provisioning in container configs.
