Heads up: Spring's release train just got compressed into one week (8 June), covering 26 new CVEs driven by AI-assisted vulnerability scanning. On 11 June, Matt Campbell and I are running a 90-min session on how to scope, sequence, and ship Spring Boot 4.1 migrations at scale.

Your coding agent is so superior to @openrewrite.github.io for tech debt reduction and CVE remediation? Then why is your source code still full of debt and CVEs after a year of agentic coding?

Wednesday at Spring I/O: @timtebeek and I run a hands-on workshop on Spring Boot migration planning. 8 microservices, version drift, shared libraries: the real-world mess. You bring a laptop, we bring OpenRewrite. springio.net/sessions/prepare-your-next-spring-boot-migration-workshop/

Asked the Spring I/O community how they upgrade Spring apps. 37% manual from release notes. 14% dependency bots. 14% OpenRewrite. How does your team handle it? More on this Wednesday at @springio.net

🧙 Gleich Java Panel: Zukunft von Java. Meine These: Die Plattform ist schneller als ihr Ökosystem und Migration ist die eigentliche Arbeit, über die wir zu wenig reden. 14:00, Bellevue, @javaland.bsky.social. #Javaland #Java meine.doag.org/events/javal...

Talk ist durch. Virtual Threads, Structured Concurrency, OpenRewrite-Analyse, Moderne CLI - und die Fragen danach haben gezeigt: Der Migrationspfad ist das, was die Leute wirklich beschäftigt. #JavaLand #Java speakerdeck.com/mboegers/mor...

Auf dem Weg zu meiner fünften @javaland.bsky.social. Die neue Java Concurrency API ist einfach, aber Teams fehlt der Migrationsplan. Darüber sprechen wir diese Woche. #Java

Today is a great day to verify you don't get yourself locked out of any 2FA-secured accounts when losing your phone. Print out back-up codes, set up fallback keys, etc. It takes just a few moments and can save you massive headaches later on.

I am live at @openrewrite.github.io Code Remix Weekly talking about modern #java concurrency. Join and drop your questions: www.youtube.com/watch?v=IFG2...

On the next Code Remix Weekly, @mboegie.dev joins the stream to show how Java 21+ virtual threads let you scale from thousands to millions of concurrent tasks. 🧵 🔴 Tune in tomorrow at 21:00 CET / 3 PM ET

Meet me there to talk about @openrewrite.github.io, understand internal coupling that slows you down and how tech stack liquidity can helps you to gain back your digital sovereignty. Step by at the @moderneai.bsky.social booth to say hi

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. Today's lab: From "what's a visitor pattern?" to "I can transform 1M lines" with tests

Will AI take my job? I don't think so, and in my second talk at @devoxx.com yesterday, I explained why. The slides are in the companion app and also at speakerdeck.com/mthmulders/w.... Enjoy!

Bye @devoxx.com ! Amazing week of community & content. Great talks with @mthmulders.bsky.social, @mauricenaftalin.bsky.social & Philippe at @oracleace.bsky.social meetup. Learned tons from Geoffrey on Open Core & advocacy. Thanks to all who joined my OpenRewrite session on digital sovereignty!
