#jfmt v0.1.0-rc1 - the very first release - is out! It's a CLI based #java code formatter, made with GraalVM, #Eclipse JDT and PicoCLI github.com/bmarwell/jfm... Let me know what you think of the general approach!

Thank you for joining me @nljug.bsky.social #jfall to learn about improving your Maven build. Ironically, I ran a bit out of time - let's blame that on my age today 🥳. Anyway, you can review the slides (including references and links) at speakerdeck.com/mthmulders/a.... Enjoy!

Curious about the upcoming 4.0 release of @maven.apache.org? Join Hervé, Guillaume, Frank and myself @foojay.io to learn more!

#Maven 4 will bring many improvements to the build tool powering millions of Java projects. Learn more about what's new in this @foojay.io podcast with Hervé Boutemy, Guillaume Nodet, and Maarten Mulders. On YouTube www.youtube.com/watch?v=2qiX... and in your favorite #podcast app.

To all my Dutch followers & friends: make sure to have your voice heard today!

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

#Maven4, #GenAI, #Java25 - what's not to like?

Enjoyed watching @mthmulders.bsky.social 's concise talk at @devoxx.com "Why I Am Not Afraid AI Will Take My Job". Available on Youtube: www.youtube.com/watch?v=w-TX... #AI #Java

🚀 mcs 0.9.1 has just been released! Check https://github.com/mthmulders/mcs/releases/tag/v0.9.1 for the details.

At least, this year we had some properly-sized #DevoxxFish again! Thank you @ddoutsiopoulos.bsky.social for capturing the moment!

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!

Slides should be visible in the Devoxx app. They're also available at speakerdeck.com/mthmulders/a.... Enjoy! #snail2rocket

Why MCP Fun at Devoxx with Lize, Dimitris, @glaforge.dev and @jdubois.bsky.social @devoxx.com @langchain4j.dev

1 down, 1 still to go #Devoxx #speaking Thanks, everyone, for joining early Thursday morning to learn about speeding up your @maven.apache.org builds. Remember: there is no silver bullet. Apply common engineering practice: measure, analyse, improve. Slides to follow soon!

One doesn't simply attend (or speak) @devoxx.com without posting this picture

This also affects my personal website & blog. As of this weekend, please refer to mthmulders.nl.

There’s no magic 8-ball behind Generative AI. It’s transformer architecture. It can do lots of things, but intelligent or sentient it is not.

#ThrowbackThursday Can't believe it's already been two weeks since I was on stage with @bmarwell.de at @javazone.bsky.social. We've discussed a structural approach to speeding up your #Maven builds. Missed it? See vimeo.com/1115842570. Thanks to @maritvandijk.bsky.social for capturing the moment!

Ever wondered what a dependency update brings in? Use latest Toolbox to figure out. #maven #java #maveniverse

Happy Birthday @sharatchander.bsky.social from all of us at the Virtual #Java User Group! 🥳

Used an app, pressed the "Delete my profile" button afterwards. One day later, I got an "Undelivered Mail Returned to Sender". Their system sent an email internally in name of my email address, but it was rejected due to my own DKIM policies...

Sigh. Some websites still do not allow + signs in email addresses when signing up. Reason enough to have my article from 2013 translated into English. Only slight updates, captures the situation of 2005-2013, mostly. blog.bmarwell.de/2025/09/05/r... #PHP #mail #email #validation #blog

Demos: github.com/bmarwell/sna... Check out my repost for blog posts :) And Maarten's blog, too, of course! ;)

Are you still spending a lot of time in testing? That does not need to be the case. Find out how to let them run in parallel! blog.bmarwell.de/2024/05/23/p... #snail2rocket #parallel #maven #java

Here is the article on how to "feed the daemon": blog.bmarwell.de/2025/04/24/f... Be sure to check out the examples as well!

Thanks to everyone @javazone.bsky.social who joined @bmarwell.de and myself in going from snail's pace 🐌 to rocket speed #maven #snail2tocket. The slides are here - closing slide also has reference to demos. speakerdeck.com/mthmulders/a...

Can we all agree that @bmarwell.de was best dressed for the occasion @javazone.bsky.social today?

During September 3 - 4, join JavaZone, one of the world's biggest Java conferences! Get to hear from our Oracle ACEs 👉 2025.javazone.no/en @theguywiththeduketattoo.com @ixchelruiz.bsky.social @francoismartin.bsky.social @mthmulders.bsky.social @brianvermeer.nl #OracleACE

So, as we move into an AI-assisted future, it becomes critical for programmers to learn how to do something they've avoided learning to do for three-quarters of a century: to write well-crafted expository prose. 6/7

LES LLM NE SONT PAS FAITS POUR FAIRE DES MATHS. ILS SONT INCAPABLES DE DISTINGUER LE VRAI DU FAUX, LE RÉEL DE L'IMAGINAIRE. TOUT CELA N'A AUCUN SENS POUR UN LLM. C'EST UN MODÈLE STATISTIQUE QUI RÉDIGE DU TEXTE SELON CE QUIL ESTIME LE PLUS PROBABLE ÊTRE LA RÉPONSE QUE VOUS ATTENDEZ. C'EST. TOUT.

That's a first: 100% acceptance rate for @devoxx.com! I'm super happy to see my new talk, "Why I Am Not Afraid AI Will Take My Job", has also been selected! See y'all in Antwerp this October!

I don't know who needs to hear this, but here's your periodic reminder that Java 25 (like 21, 17 or 11) is not an LTS version: youtu.be/x6-kyQCYhNo?... Thank you, @nipafx.dev, for once again making this very clear!

Happy π day to all who observe!

🚀 mcs 0.7.6 has just been released! Check https://github.com/mthmulders/mcs/releases/tag/v0.7.6 for the details.

Underrated feature of @maven.apache.org !

RIP Java Applets. You made Java popular and helped it grow to what it is today. JEP 504: Remove the Applet API has been proposed to target (openjdk.org/jeps/504), so there will be no more applets with the next JDK (JDK 26).

Dutch parliament: passes law that makes it illegal to help undocumented immigrants. Dutch police: this is a bad idea and we don’t want to cooperate with this. www.politie.nl/nieuws/2025/... Resistance is a matter of wanting to.
