JEP 527, "Post-Quantum Hybrid Key Exchange for TLS 1.3" now proposed to target JDK 27: openjdk.org/jeps/527 mail.openjdk.org/pipermail/jd... #jdk #openjdk #tls #crypto #pqc

The virtual JChampions Conference 2026 (jchampionsconf.com ) organised by @jchampionsconf.bsky.social will start on Jan 22. Have a look at the schedule, there are many great sessions by recognized Java champions. Get your free ticket at www.eventbrite.com/e/jchampions... #java

My New Year's resolutions for my software development in 2026: focus even more on quality, sustainability and maintainability. #java

We have added a new tool called "FxTools" to the @jfxcentral.com website at www.jfx-central.com/tools/fxtools It is a toolkit that provides image processing, color picking, SVG path extraction, font preview, and more. Author is @leewyatt.bsky.social @frankdelporte.be

Agree. And I'd like to add: do what you believe needs to be done. Because you think it's important that it's done. Not to get a reward.

I highly recommend this book. Java is an excellent language/platform for embedded development. It is not focused on itself, but on doing the job. And it's damn good at that.

Great post. It's a topic that I think about often too: what will happen (but especially, what should we do) after the bubble popped? I hope taxpayers won't be the victims of this circular deal game. I also hope some of the technology will then be used for good, human purposes.

This is a major issue indeed. On the plus side, I still believe that efficient, well-written software (running locally or in cloud) requires much less CPU(/GPU) power/RAM than most of the crap code running inside cloud containers today. So you can still save $ by not relying on cloud services.

How the creator economy destroyed the internet

Same for journalists. Unfortunately, even traditional media often simply quotes an X post. I prefer they directly speak to politicians, and ignore what they say on X. Don't feed the monster, but also don't ask the monster.

I strongly recommend the recordings of the JVM Language Summit 2025: www.youtube.com/playlist?lis... I watched the Leyden/Vector API talks this weekend, helpful to learn about experiments and lessons learned at core level. Understanding this makes you a better Java developer, imho.

I prefer to write software that I believe is needed, helpful and "ethical". Often that is associated with free/hobby/spare time, and indeed it often is. But that doesn't mean at all I'm against making money from software development (several friends have done great with it, and I'm happy for them).

Great article on Foojay: foojay.io/today/the-ar... Love this quote: "sustainability start at the keyboard, not in the billing dashboard" I totally agree. I often wonder how much CPU usage could be saved if all code running in clouds would be top-optimized. Pretty sure it's huge. Way more than 50%.

Strange API's need some love. I'm currently working on "named qubits": Qubit ctrl = new Qubit(); Qubit target = new Qubit(); Program p = new Program(ctrl, target); p.addSteps(new Step(new Cnot(ctrl, target))); Easier to work with then referring qubits by index only. #quantumcomputing #java

Quantum Computing and AI are completely different things (although there are synergies). The A in AI stands for Artificial. Quantum Computing, otoh, exists because of fundamental phenomena in Nature.

Such a good write-up of making Signal resilient to quantum-based attacks Why Signal’s post-quantum makeover is an amazing engineering achievement arstechnica.com/security/202...

Keep in mind that the Gluon LTS releases of JavaFX 17u and JavaFX 21u are free to download and use. We do offer an LTS service (gluonhq.com/lts) but the releases themselves are really free. We don't want to charge people for creating JavaFX applications. No reason to pay unless you need support.

Looking for feedback: The JavaFX Properties/listeners approach if really powerful to bind UI components to changing values. But it is often over-used and the main source of performance issues. It's very easy to kill performance by adding a listener to a property that is modified during layout.

JavaFX developers using Windows: please help the development by doing some performance test for Direct3D 12: mail.openjdk.org/pipermail/op...

The impact of openjdk.org/jeps/510 is huge. Developers using OpenJDK now have many more tools/convenience to work with KDFs. They can more easily take major parts of security/encryption in their own hands, instead of relying on proprietary (cloud-vendor specific) implementations. #openjdk #java

Here is the new #JavaFX #LinksOfTheWeek, published on www.jfx-central.com/links. Thanks to Paul Krill Bruce Haddon @abaddongtz.bsky.social @frankdelporte.be @johanvos.bsky.social @steveonjava.bsky.social @devoxx.com Troels Mortensen @foojay.io Happy reading, and have a lovely #Java weekend!

A great conversation with Adam Bien at the W-JAX 2025 in Munich about his existing blog posts aligned with LLMs to ask the system about his own achievements for current projects: „What would Adam Bien say?“ @adambien.blog @jaxkonferenz.bsky.social

Part 6 : Java on Mobile - #JavaFX At #Devoxx Belgium 2025, @frankdelporte.be took the camera and microphone to talk with several speakers and visitors. This time with @johanvos.bsky.social and Stephen Chin... youtu.be/OrhGyTGJgOg

The reason for creating tests is not to achieve 80% code coverage, but to gain the assurance that the application will still work after a change.

Working on OpenJDK for Android: in 43 seconds, I run an app on my phone, make a change in OpenJDK (change dlllookup into dll_lookup), rebuild OpenJDK, link it with my app, push to my phone, run again. OpenJDK development is extremely efficient. #java #innovation #mobile #openjdk

The openjdk-mobile project (github.com/openjdk-mobile) provides daily OpenJDK builds for iOS, packaged as XCFrameworks. Recently, there was a failure because I had to update the bootjdk to 25. Apart from that, very smooth! #java #innovation #openjdk

Totally agree with this one.

One of the coolest things about our @bejug.bsky.social community? Everyone can participate and help out. Check out this amazing banner @lomagnette.bsky.social made!

What an amazing week! #devoxx Belgium 2025 did not disappoint! So much great content and friendly faces I've finally met IRL! And wow, they already posted to Youtube all recordings! You can check out my talk about #paketo #buildpacks youtu.be/RX9zwgHuNmA

Devoxx registration: what they promised versus what you got. (but hey, it was a great conference, really enjoyed talking to so many interesting folks!)

New #JavaFX #LinksOfTheWeek, published on www.jfx-central.com/links. Thanks to @johanvos.bsky.social @trixon.se @crschnick.bsky.social @sunnykentz.bsky.social @sreimers.bsky.social Michael Hoffer Florian Enner Abid Maqbool Haidar Ali @dlemmermann.bsky.social Have a lovely weekend!

Now at #devoxx: @sreimers.bsky.social talking about jtaccuino. #java #javafx

Safe travels to all Devoxxians heading to Antwerp! See you soon at #Devoxx 🚆✈️🚗🚴🏼

I can now run HelloFX on an iPhone. This required only really minor changes to OpenJFX and OpenJDK, and I'll update github.com/openjdk-mobi... as soon as I find some time. Most of the work (> 99%) went into understanding the tons of options in XCode. (1/2)

In 2023, Signal was the first mainstream messenger to enable post-quantum cryptography. We’re still ahead of the (elliptical) curve, implementing a new hybrid PQ ratchet ensuring Forward Secrecy & Post-Compromise Security even in a post-quantum world. signal.org/blog/spqr/

The final #Devoxx Belgium 2025 newsletter is out! 🚀 First-time Devoxxians, this one’s especially for you, don’t miss it! redirect.devoxx.be/nl3/w2QUJQCh...

Looking forward to #Devoxx Belgium next week. Excellent speakers/sessions, and great atmosphere. I'm more than happy to do interviews about Java/JavaFX on Mobile and explain github.com/openjdk-mobile so ping me if interested. (also happy to chat about quantum computing, javafx, science, cycling...)

Progress in the OpenJDK-mobile story. Repository created that has actions to build openjdk+openjfx from head of both upstream repos. github.com/openjdk-mobi... I needed this for desktop, and it makes mobile easier. Linux-build that runs HelloFX (without setting modulepath etc) is now working.

Not going to let this happen. #resist

Correct me when I'm wrong on this, but I have the impression that over the past decade there is a decreasing attention for performance when developing Java "cloud" apps, and more attention for cloud tools that solve performance by "scaling in any direction you want" (resulting in higher cloud bill).

Java 25 / JDK 25: General Availability: mail.openjdk.org/pipermail/jd... Features: openjdk.org/projects/jdk... Downloads: jdk.java.net/25/ #Java25 #JDK25 #OpenJDK #Java

JavaFX 25 is available! Released the same day as Java 25. Get the SDK from gluonhq.com/products/jav... or download the maven artifacts from maven central.

To be very clear on the broader OpenJDK-mobile initiative we accounced last month with @gluonhq.com (openjdk-mobile.github.io) : this is all based on open-source tech (github.com/openjdk/mobile). We deliberately avoided dependencies on company-owned products. #techfirst

In our local JUG, javabin Trondheim, we’re celebrating Java 25 on Monday. In addition, I’m presenting about QC and @johanvos.bsky.social’ Strange simulator! I’m not through the whole book, yet, but I’m already totally fascinated!

If you're on mac, please try JavaFX 26-ea+6 and share feedback. Tip: add `-Dprism.verbose=true` which will confirm you're really using metal, as shown below. Many thanks to Kevin, Ambarish, Ajit, Jayathirth and others for their great work.

Column Hendrik Vos | "Het is van levensbelang om scherp te blijven en nooit ruim baan te geven aan ijdeltuiten die zich onaantastbaar wanen, verheven boven de wetten van het ondermaanse – of ze nu resideren in het Witte Huis, het Kremlin of het ‘Cremlin’ (het gemeentehuis van Aalter)"

There are so many cool performance tricks for JavaFX that I sometimes think I should write a book about it. But that takes a huge amount of time. I'll think a bit more about how to deal with this. #java #javafx
