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

The second session had @rfscholte.bsky.social sharing how to minimise logging in your Maven builds and tests at @jugnoord.bsky.social 👍 Less is clearly more this way 🤩

@jagovreede.bsky.social sharing his experience of three years with @handle.invalid and even @graalvm.org in production at @jugnoord.bsky.social yesterday 😎

Looks like 🦋 is fully available again 🤩

Tech conferences aren't dead, they’re evolving. According to DevoxxUK’s Mark Hazell, the real value isn't the info (you can Google that); it’s the focused learning, the community & the dev in the next chair who solved your bug. Full ShiftMag interview: bit.ly/3OBf4X9 devoxx.co.uk | 6 & 7 May

DaVinci resolve for photos just announced, didn't expect that but will have to check it out 🤔 www.blackmagicdesign.com/products/dav...

Goodmorning Barcelona! This afternoon I’ll be talking graph databases and data modelling! 16:30, room 4! Be there @springio.net! #java #kotlin #neo4j #graphdatabases #conferencespeaking

Interested in performant modern Java code using records and immutable behaviour? 🤔🚀 My 15 minute lightning talk at last week's @amsterdam.voxxeddays.com is now available on the Devoxx channel: www.youtube.com/watch?v=JO_X...

In 2021 my developer spark was almost dead. I tried every technical fix I could think of. The actual fix surprised me. Still does. lomagnette.github.io/posts/reigni...

Really happy to have spoken at @amsterdam.voxxeddays.com ! Next ahead is @springio.net on Tuesday at 16:30! I would love to see you there! #springio26 #neo4j #graphdatabases #java #kotlin #publicspeaking

The joys of AI subscriptions 🤣 Even eating up your token budget answering questions about the subscription 🙃

It’s been a few days since I was impacted by the #Oracle layoff. I wanted to acknowledge the #Java DevRel team that’s still there, as well as other folks/companies continuing to also engage with the Java community. Please give it a read: www.linkedin.com/posts/sharat...

Looking for work. Will DevRel for coffee or wine 😁

Looks like I've picke the right room to start @amsterdam.voxxeddays.com with @maritvandijk.bsky.social & Michel opening 👍

Well, my #Java journey has come to an end. Today my role at Oracle has been terminated. I’m open to any job leads y’all may have.

Ah, daylight saving time - all of the jetlag, none of the travel... 🤪

👩‍💻As I am preparing, I am sharing with you the following: 2 #conferences coming up 😬! April 1st, @amsterdam.voxxeddays.com about fun and passion at work: amsterdam.voxxeddays.com/talk/?id=1757 April 14th, @springio.net about using #neo4j: 2026.springio.net/sessions/thi...

The analog opening act at connect.frl never disappoints

That's a fast sunset 🫡 www.theverge.com/ai-artificia...

Java keeps getting faster… without us changing much. The JIT improvements from 21 → 26 alone are significant (Netflix saw up to 3.5x in cases). Brian Goetz said: “Thinking is hard.” Feels true. Code gets easier. Performance gets “free.” Thinking is the work. Before you optimize—try Java 26.

Great to see @hanno.codes and #Java 26 on hacker news today🤩 news.ycombinator.com/item?id=4741...

F5-ing @sdkman.io 😅 Hopefully seeing some distro's later today.

If you have a tool that can produce stuff faster than before BUT at lower quality/worse customer experience: when would you use that tool? Personally, I'd use for prototyping + throwaway (quality unimportant) Def not for customer-facing stuff... until quality is as good or better vs before

How does #Java Vector API accelerate parallelizable computations? I explored it in my new article (with an example): Estimating value of pi (π) using Monte Carlo Simulation and Vector API Read it here: www.balarawool.me/Vector-API-P...

I'm usually not that much into rap, but this is very well done 🤩 www.youtube.com/watch?v=zpvd...

Maven central status: publishing, created: 1 hour ago 🙃

If you haven’t listened to @rdehuyss.bsky.social ’s interview on the Marco Show yet, stop what you’re doing and get the episode: you’re in for a treat! Ronald is a wonderful human being, smart and funny. He runs a fascinating OSS project @jobrunr.bsky.social and … he ”makes money selling a .jar” 😎

@glycin.bsky.social "Please RickRoll me" P.I.P.: Certainly 🤩🤣

Getting ready for @glycin.bsky.social at @jugnoord.bsky.social sharing his AI pair programmer P.I.P.

I don't always have time to watch Ted's streams, but it's great to see him following up with a blogpost on what he encountered and learned each episode - such as migrating Spring boot 3.5.x -> 4.0.3 😎

If you were in Coimbra last May, you’ll remember it. Two days of technical depth. Sharp questions. Packed rooms. JNation returns to Convento São Francisco on 26–27 May. A new edition is in the making! Last year’s highlights below. #JNation #Java #Coimbra

Let's talk about #Java's checked exceptions - smartly. Not whether we should have them (that ship has sailed) but where the friction comes from and what could be done to reduce it: www.youtube.com/watch?v=99s7...
