Matthias Haeussler

Hi 👋 to all my new followers 😇 I will try to give Bluesky a new chance and noticed a lot of new people following me. Thanks for that 😇 Most of the stuff that I post will be about Java and CNCF-related technologies (and conferences around it). Looking forward to interact!

Containers are the default path to prod. That also makes the supply chain a major risk. At Devoxx UK, the interest in Docker Captain @maeddes.bsky.social’s Docker Hardened Images talk was a clear signal that devs are actively looking for better ways to handle container security.

The countdown to @devoxx.uk is officially in the "getting real" phase. From the latest in #Java & #CloudNative to the cutting edge of #AI agents, the vibes are going to be immaculate. Who are you most excited to see on stage? 👇 devoxx.co.uk

My #JavaLand talk starts in around 30 minutes. I will look at the history and presence of #SpringBoot and #Containers Happening in Room Studio at 15:00

The new year brought some unexpected news: I've been impacted by a restructure at Broadcom. Now open to new opportunities as a Senior/Staff Java Developer (remote from Madrid). Happy to connect if there’s a potential fit. 👉🏼 www.linkedin.com/in/ivanlopez... #OpenToWork #Java #RemoteJobs

Since I was called out in person during the talk I should probably share it, too :-) Jokes aside. This talk is an excellent reference for @graalvm.org and you all should watch it!

Every time I fly, I always pick a window seat. I stare out of it and watch the world go by. We live in such a beautiful world. It’s big enough for all of us.

Very interesting talk if you're building container images - especially for the JVM. I had not really explored buildpacks for this. Definitely gave me some things to think about

Here is my updated YT video about Java Container Builds: www.youtube.com/watch?v=HFhI... Thanks a lot @cschuszter.bsky.social for providing an instant fix :-) #container #java #buildpacks #jib #dockerfile #voxxeddays #cern

Oooh @concourse-ci.org is getting some love in 2025! blog.concourse-ci.org Good luck to the team - it’s a neat project! I haven’t used other CI/CD/orchestrators in a long while, save for basic GH actions. I wonder if the CI world has caught up to the good ideas Concourse brought to the table.

Imagine if companies spent 1/10 of the money training their employees as they’re spending on training AI

Many thanks to everyone who took the time to submit to this year's @voxxedzurich.bsky.social, we received almost 400 submissions!🤯 The accepted sessions and speakers are now on the website: zurich.voxxeddays.com Happy to see both familiar and new faces!❤️ #VDZ25 @voxxed.com

I am currently submitting talks to @devoxx.uk and Devoxx Greece (only 2 days left!) And I noticed that in the speaker section @bsky.app is now treated as first class citizen 🙂 Way to go! 🚀

I hope they ship to Europe, too 🙂

The CFP for @arcofai.bsky.social Arc of #AI 2025 closes on next Tuesday: December 3 Have you sent in your proposals? www.arcofai.com/cfp

In this InfoQ article, Juergen Hoeller and I answer to Karsten Silz questions about the Spring roadmap, the JDK baseline, the switch to JSpecify and the strategic alignment with GraalVM and Project Leyden.

A long time ago, I created with the #learnk8s folks this list of free trials/credits for @kubernetesio managed services -> github.com/learnk8s/fre.... Are there new providers who want to add their details, or is this list still relevant? Please RT!

I don't have any fancy starter packs yet, but following @tiffanyfay.dev is certainly a good start for everyone here. If you do so now, you can also say congrats, cause it's her birthday 🎈🎊 Happy birthday, my dear friend and all-time co-speaker. Wish you all the best and many more talks with me 😇

If you are interested in helping to make the #OpenTelemetry getting started experience better, please take a look into this proposal: github.com/open-telemet... How you can help: * Review the proposal and share your thoughts * Volunteer to participate in the real work

The next version of Python will be 3.14. Shouldn’t they just call it Pi-thon? 🤔
