Photoalbums for @devoxxpl.bsky.social by @ddoutsiopoulos.bsky.social are available. As usual with wonderful shots of the speakers -and- audience 🤩 Wednesday: www.flickr.com/photos/bejug... Thursday: www.flickr.com/photos/bejug... Friday: www.flickr.com/photos/bejug...

@piotrprz.bsky.social 🤘

127.0.0.1 😅

So, the train signs are hit by lightning, train driving slowly towards Zwolle and unclear if it'll arrive in Leeuwarden 😅

Oh dear... Koade oranje yn Fryslân oant 2.00 oere fannacht.

Scratch that, apparently chaos on the track, so will have to by Centraal 😅

Just arrived at Schiphol, ETA 🏠 00:30

Wasn't expecting to see @hansolo.eu use the "other" Star thingie 😅

TIL about docs.oracle.com/javase/8/doc... 🫢

@andresalmiray.com 404 😕

@nipafx.dev Valhalla, when? 😅 #AskingFor @coduinix.bsky.social

Enjoying @pbakker.bsky.social sharing how Netflix uses Java in '26 at @devoxxpl.bsky.social 👍

Reviewing CfP submissions with walls-of-LLM-generated-text, just scrolling by fast to click 🙅 and reason "LLM submission". If you can't even bother to write a proper proposal for your audience, I won't bother reviewing it that way 🤷

"Don’t ask someone to read/review what you haven’t read or reviewed yourself." Some good stuff on working with AI in a team, by @skamille.themanagerswrath.com skamille.medium.com/guidelines-f...

This is horrible behaviour by an open source library developer: two weeks ago a version was released which added prompt injection on purpose causing agents using it to delete the implementation on the developers device. If you don't agree with LLM usage, voice it, don't damage others work 🤔

GraalVM Community Summit is back for its 6th edition! 🚀 Join our team, contributors, and partners in the JVM ecosystem for two days of presentations, working sessions, and collaboration on the future of GraalVM! Learn more and join: graalvm.org/community/su...

JDK 27 has been branched from the main line and is now in Rampdown Phase One: mail.openjdk.org/archives/lis... openjdk.org/projects/jdk... #JDK27 #OpenJDK #Java

i wrote a post about the growing divide between AI skeptics and AI enthusiasts. wins and costs are both real, but too often fall on different groups of people. when you're only experiencing half the story, it's too easy to write each other off. charitydotwtf.substack.com/p/ai-enthusi...

For those running towards Caveman with the updated costs, consider writing your "own" solution, as covered in medium.com/@KubaGuzik/i... (Yes, it's already two months old...)

Me watching all the GitHub Copilot users burn their monthly token budget today 😅

Our next meetup will be on June 23rd at DUO in Groningen featuring @josroseboom.bsky.social sharing how to be awesome with ORMs and @boukenijhuis.bsky.social showing how to migrate to a European cloud. Sign up at our meetup page to join this inspiring session!

May 23, 1995 31 years and still going strong. Happy birthday, #Java! Thx to the #JavaCommunity that continues to keep it vibrant!

After a year of daily AI-assisted coding, I wrote down what actually works — spec-driven dev, skills as guardrails, incremental verification, and the 4 gaps. ionutbalosin.com/2026/05/tami... AI is an amplifier. It magnifies discipline and chaos with equal enthusiasm. #AI #SoftwareEngineering

New Vivaldi just dropped. And by new, we mean NEW ✨

OpenRewrite now has a Kotlin DSL for recipe authoring. Declare a before/after pattern, get a generated recipe at compile time. No annotations, no template class, no reflection. Migration, performance fusions, and Android deprecation patterns all ship on day one. Full breakdown:

Over the years, GraalVM compilation time has drastically improved. On my MacBook, it takes a few seconds. It’s actually the fastest operation in a development workflow that includes GenAI agents. Everything else is slower because GenAI-powered. It makes you think, right?

🎯 JEP 534 updated to target JDK 27 Title: Compact Object Headers by Default Type: feature Component: hotspot / runtime Release: 27 See openjdk.org/jeps/534

#JUnit 6.1.0 is released! 🕑 Built-in extensions for locale, time zone, and system properties 🚮 Configurable TempDir deletion strategy 🏃‍➡️ New org.junit.start module for compact source files ⚙️ Execution mode config for dynamic tests 🏊 New parallel test executor impl. docs.junit.org/6.1.0/releas...

Install #nexus or #artifactory or others in your startup, big tech, fintech or wherever you work and consume from #maven central! central.sonatype.org/faq/429-error/

Five legends and so many more great talks! Looking forward to the conference in two weeks 🤩 And it looks like they still have tickets available 👍

I'm not excited by what AI can do. I'm excited by what I can do.

Another good excuse to use a static site generator such as Hugo for your blogs if you don't include any interactivity such as comments 😎 And with the input in markdown, you won't even need an MCP server 👍

Did you know that GraalVM provides automatic metadata for many popular Java libraries, so you can have a smooth experience with Native Image out of the box? — 1200+ libraries 📚 — 18K+ tested versions ✅ — 2M+ tested LOC 🤯 More details soon!👀 github.com/oracle/graal...

Had a great evening at @jugnoord.bsky.social. Good food, friendly people, and interesting conversations. I presented my new session “Never a null moment with JSpecify”, which sparked some good questions and discussions. Thanks everyone for the questions, feedback, and conversations afterwards.

Had a great time at @jugnoord.bsky.social today with @coduinix.bsky.social making nulls disappear with #JSpecify 🧙‍♂️

The most German thing I've seen this week is two people livestreaming a speedcamera in Berlin, tapping beer bottles whenever someone breaks the 30km/h limit 🤣

Tomorrow I am speaking at @jugnoord.bsky.social ! Are you joining us there? Subscribe here: meetu.ps/e/PZ1gr/tBNX... #JUGNoord #Friesland #Groningen #Java #neo4j #softwareengineering

That is the unfortunate truth... LLMs accelerate in both directions 😅

About the latest shenanigans from Google: Our team has been disabling stuff from Chromium since the first version of Vivaldi. We've also been very outspoken about our dislike of the built-in AI trend in the browser industry, so yes, we disable all Gemini-related features in our code. ✌️

📢 Reminder for all JCON attendees! If you’ve pre-ordered a T-shirt, please make sure to pick it up at the info point. ❗️We will not ship the shirts, so tomorrow is your last chance to collect yours! Don’t miss it—grab your shirt before you leave 👕

Team squirrel 🐿️ on stage! What happens if you put @piotrprz.bsky.social and @maritvandijk.bsky.social on stage teaching about modern Java at @devoxx.fr ? A crossover between a comedy show and a legit experiment.

Copyright safe memes with @maritvandijk.bsky.social and @piotrprz.bsky.social at #JCON - and lots of modern Java 🤩

Thank you to @jcon.one and @richard.fichtner.dev for this leadership award. Building out the #Java community has been a career highlight. #JavaTogether

If you're at JCON Europe today, join me in the Mentorship Hub (upstairs from the Cinemas) at 14:30 to play JitterTed's TDD Game, learning about Test-Driven Development, as well as how we collaborate affects the work we do. jcon.mentorshiphub.org/#session=TE...

If you haven't participated in one yet, I can highly recommend the mentorship hub by @brjavaman.bsky.social and a number of top speakers and Java Champions at @jcon.one this week. Full program is available at jcon.mentorshiphub.org

GraalVM CE can now sandbox untrusted JavaScript and WebAssembly code! 🚀 As AI generates more and more of the code we run, the ability to execute it safely matters more than ever. We have more coming that builds on this, so stay tuned! github.com/oracle/graal...

Time for some coffee, ETA at JCON shortly after 1300
