The first part of OpenJDK’s Project Valhalla, JEP 401 (Value Objects), has been integrated into JDK 28 as a preview feature and is now available in the early-access builds. More information: openjdk.org/projects/val... #JDK28 #OpenJDK #Java

Today I realized that the evolutionary justification of the existence of orange cats is because their prey is dichromatic, meaning that they appear as green to their prey.

Now it is a Candidate JEP openjdk.org/jeps/540

One of my kids attended a summer break activity today and when I picked him up afterwards he was complaining that one of the adults had been misleading the kids. Turns out that the adult had told the kids that Earth is round. A sphere. My kid: No it isn’t, it’s a geoid. He’s 12yo 😅

Spent a bit of time to pretend to be a network technician over the past month and moved many devices to use wired ethernet—not only does this really improve latency for those devices, but it also has freed up a bunch of bandwidth for the wifi-connected devices. Worth it!

I invite you to gather around at #JavaOne to hear my presentation on "Extending the Functional Pipeline with Gatherers". Register by Feb 9 with code J12026SSM for a $50 off. social.ora.cl/6002h6oOr

Asked one of my sons (11yo) what he’d do if he won $4m. Him: Well first of all I would invest half in the stock market by buying shares in a number of different companies that I believe in so it isn’t as risky. Me: 😲

JDK 26 has been branched from the main line and is now in Rampdown Phase One: mail.openjdk.org/pipermail/jd... openjdk.org/projects/jdk/26/ #JDK26 #OpenJDK #Java

I'm thrilled to announce that the next episode of the #JEPCafe on #Gatherers will be published tomorrow. And if you have the time, we can watch it and chat together on YouTube. Just like we used to do 30 years ago on IRC 😄 www.youtube.com/watch?v=fgQQ...

Hey #Java devs! At @devoxx.com, the Java Team at #Oracle is hosting an "Ask The Architects" panel. Post your questions here by Wed 23:00 UTC! Then check out the recording to hear the experts’ answers (as many as we can). 📝 Please read the questions others have suggested to prevent double-posting.

Almost time for Devoxx BE! Putting the finishing touches on my presentation over the weekend, and I’m looking forward to meeting up with friends, colleagues, and talking to #java developers in person!

Joiners now support timeout in this new version. Sweet! 🙂

Amazing news 💥!!! JavaOne returns in March 2026 ❣️ Checkout all its details and save the date 🎉!!!

I’m really looking forward to speaking at JVMLS in early August this year, so it’s time for me to start preparing: openjdk.org/projects/mlv...

#Java 25 is frozen! 🧊 It finalizes 11 features in the language (e.g. simplified main), APIs (e.g. scoped values), and runtime (particularly AOT and JFR) and has 7 more in preview. Walk through the complete list in the latest Inside Java Newscast: www.youtube.com/watch?v=T5q7...

JEP 470: PEM Encodings of Cryptographic Objects (Preview) has been targeted to JDK 25 - openjdk.org/jeps/470 This is a Preview API, so we have time to make changes. Let us know if the API is easy to use and satisfies your use cases. #openjdk #crypto #security #java

After virtual threads, structured concurrency is the next big step for concurrency in #Java. All the more important to get it right! JEP 505 overhauls the proposed API in Java 25. Learn all about that in the latest Inside Java Newscast: www.youtube.com/watch?v=vLJD...

We integrated #java 's new Stable Values feature just now! This will allow developers and library developers to benefit from the "secret" @Stable annotation that the internal JDK code has been using for years. This can bring significant performance improvements to your code! openjdk.org/jeps/502

My presentation on #Java Stream Gatherers at #JavaOne is now available: youtu.be/v_5SKpfkI2U?...

#java 24 is out and here is a summary of the performance improvements we made: inside.java/2025/03/19/p...

I’ve taken Ghostty for a spin over the past days and I think I am starting to prefer it over iTerm2.

Today ended with me being nerd-sniped by @pminborg.bsky.social 😅

Nice video by @josepaumard.bsky.social on enhancing #Java #Streams with #Gatherers since #Jdk22

And JDK 25 is now underway! git.openjdk.org/jdk/commit/5... #OpenJDK

Hello, Bluesky!

If Stream Gatherers improve the solutions to your Advent of Code assignments please let me know 👍 #java #streams #AdventOfCode

November has been a good month for #Java #Security! JEPs Integrated: - 478: Key Derivation Function API (Preview) - 486: Permanently Disable the Security Manager - 496: Quantum-Resistant Module-Lattice-Based Key Encapsulation Mech - 497: Quantum-Resistant Module-Lattice-Based Digital Signature Alg

There will be 24 JEPs in JDK 24. openjdk.org/projects/jdk... #OpenJDK #Java

During dinner, out of the blue, someone says: ”So, Viktor, I’ve been meaning to ask you about your position on the Riemann Hypothesis.” Me: 😬
