What if... we could build a JDK including JavaFX, using the jdk build system?

As a POC, I added 3 javafx modules to my fork of openjdk/jdk and built them on Linux.

The openjdk/jdk build system is excellent, and it required only minimal changes to do this.

See https://github.com/johanvos/jdk/tree/openjfx

Definition of irony: a great and well-written post on the national news website (https://www.vrt.be/vrtnws/nl/2025/01/23/hoe-meta-en-x-de-geest-van-het-wereldwijde-web-hebben-verraden/) about (a.o.) the power of X and Meta contains a major area with buttons to share it on... X and Meta. (no links to e.g. Mastodon or BlueSky)

If you want polarisation and hate to increase, this is exactly the thing you have to do... :(

About https://bsky.app/profile/katie-drummond.bsky.social/post/3lg6opvfxac2j:

I have a question. How can we convince children to do their best in school, to study, to write code, while the world is increasingly influenced by people who don't study, but speak loudly and spout nonsense in a way that attracts attention?

The word "tech" is increasingly associated with negativity (e.g. big tech, tech-CEO's). It's up to us, people working on technology, to show that real "tech" (not the marketing stuff from Google, Zuck, Musk) can be great, cool and friendly.

btw, I don't like it when e.g. Meta is called "Big tech". Big, yes. But tech? Really?

Also, I know some CEO's of tech companies who are really great and kind, so please don't over-generalize ;)

If my reaction to a code snippet is "HUH? euuh.... wait... aaah.... ok ok ... wow! omg! billiant!!!" there is a reasonable chance that the answer would be "James Gosling".

Reading his code is often like reading an intriguing and initially weird but excellent book with a plot twist that you didn't expect and that blows you away.

In a traditional quiz, there is (or at least was) often a round where 10 music fragments are played, and you have to recognize the composer.

I think something similar can be done for code. 10 code snippets are shown, and you should write down the author.

I highly encourage WhatsApp users to switch to Signal (https://signal.org). You get the same (or better/more) functionality, but you don't depend on the (financial/political) whims of a commercial company like Meta. Signal is a non-profit org, just to enable messaging.

Your existing network will gradually switch as well if you make the first move :)

I am really bad in rejecting PR's. No matter how much advice I read about how to deal with a bad PR, I find it hard as I don't want to be the bad guy.

But then, I'm the guy who says 2 years later: "I knew this was a bad idea".

If there are things that can be fixed in a PR, that is a different story. But if imho the PR is a bad idea in general, it's another game.

A big shout-out to Ken Fogel (@omniprof) for all the effort he puts in the JChampions Conference (jchampionsconf.com).

An organisation like this requires lots of fun but also non-fun things to do.

Ken and team are doing a great job in showing the world how great Java is. Thanks.

It's easy to claim there should be more focus on in education, and it is never a black/white thing, but I believe it would be good to spend more time on the Fourier transform.

I wanted to check how good ChatGPT is at some basic quantum computing questions. Let's start with simple math. If n = 2, the number of qubits required for Shor's algorithm is 2n+3.

After wrong steps, ChatGPT gives the correct answer. Because, 2 + 6 + 1 =... 🤔 😂

In case the creator of the wheel does not document the exact working, or does not answer your questions, I think it is fine to reinvent your own wheel.
