Currently drafting the Spring Boot 4 / Java 25 migration plan for my current customer. How is your migration plan coming along?

I've been testing with the different milestones and RCs, but now it's time to make it real!

Heard from a developer today: "I ran out of AI credits and can't continue the task."

It's concerning to see devs can't ship code without AI. Will this become the norm for the next generation?

We're told AI gives us a productivity boost, but maybe we're becoming too dependent.

🎾 Nice combo for 2026!

Spring I/O 2026 will take place the same week as the Barcelona Open Banc Sabadell, one of my favourite weeks of the year as a tennis lover. I never miss the tournament!

If you join Spring I/O, you can also catch some world-class tennis right next door.

Tried the new Sonnet 4.5 with Junie, it consumes considerably more quota than GPT5 and the quality gains aren’t clear enough, not worth the change as of now.

AI is reshaping the entry-level job market.

Some junior roles might be disappearing but on the other hand, companies are desperate to add AI into their systems and workflows. And I believe that is a shortcut for new grads.

I’ve been setting up GitHub self-hosted runners lately to execute jobs from GH Actions.

My current client has many security and compliance requirements, this allows having full control over the environment, using any hardware, lower costs and even accessing resources behind a VPN.

You can learn 100 JavaScript frameworks…
or you can learn Java and Spring once, and it’ll pay you back for years. 💚
