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 😅

I am terrible at parties. I caught myself using the phrase ”so I read this research paper the other day which …” like 5 times within the span of 20 minutes today.

Weekend musings: what I am most proud of is not the things I’ve built (or helped build) but learning that something I did or said had a meaningful impact on someone else’s way of thinking. I definitely did not see that coming when I started working some 25 years ago.

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!

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.

The kids wanted to go to a sci-fi convention and one of them wanted to cosplay as Chainsawman 😅 We built this together from cardboard, PVC-pipes, aluminium tape, and lots of hot glue 😆

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! 🙂

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
