JavaFX is missing a native Switch control — every major UI framework has one except JavaFX.
I've implemented a SwitchButton with full theme support. Hope to contribute to OpenJFX.
Thanks @dlemmermann.bsky.social for his help!

OpenJDK is faster than GraalVM*
It's around twice as fast in one particular area. Read more in my latest tiny blog post at mostlynerdless.de/blog/2026/01...

Any #JavaFX people experience removed nodes being stuck around in memory after they've been removed from the scene graph?
If I have a node that has a ~500 MB byte array, and then I remove it, I should be able to expect that to be freeable right?

I reverse engineered DexProtector, the security solution protecting applications like Revolut and other banking apps.
From custom ELF loaders to vtable hooking, here is an insight into how these protections work and their limitations.

I spent about two days learning and implementing atmosphere rendering for planetary views from space. The tutorials and other sources I found on it were prettty lacking in implementation details but I got there in the end. Too late now, but does anyone have any recommends? Should I write an article?

If you're using the JavaFX "Flowless" library for virtualized controls and are observing sluggish performance, do not add stylesheets to the Virtualized Node. Add them to the Scene. I observed an immediate 10x performance boost by doing this.

Now Recaf 4X can inline return values of simple static methods (like a xor string decryption call in this case)

Recaf's interactive deobfuscation window now lets you specify how many passes to run. For some obfuscation patterns that can't be one-shot in one linear pass (opaque control flow leading to more opaque control flow repeated N times) increasing the pass count to N+1 reduces it completely.

Australia's decision to require age/identity verification, including facial scans, in order to do a Google search is dystopian.
We're watching the death of an open, anonymous internet, and the gradual takeover of information online by the state — under the guise of protecting children.

Australia is quietly rolling out age checks for search engines like Google
Just as Australians are adjusting to the idea of having their ages checked for social media, age assurance rules are being applied to search engines and many other corners of the internet.

Updates to how some of the transformers work has cleaned up the output on most obfuscated samples I have. Here's a demo on a Minecraft server plugin getting optimized back to almost perfectly legible source.

Honestly, fuck Hotspot sometimes. A method body can just *lie* about how long its data is. Obviously nobody who makes a class parser is going to be keen on this until they see it in the wild. Does the spec say anything about this? Of course not!

Getting tired of the "AI can generate code much faster than you" slogan. Most often, the problem is not generating code. The hard part is understanding the code. What is it doing, how and why? And is that what you expect it to do?

Alright, I rewrote my #JavaFX docking framework, BentoFX, from scratch (again) after incorporating it into multiple projects and learning what the pain points were with the existing architecture.
Here's what Bento looks like in practice:

In more positive news, I've made a lot of progress on BentoFX. Its still not at a stable release point, but while working on porting Recaf to use it I noticed and cleaned up a lot of bugs and lacking capabilities.
