Java 26 is “boring.” And that’s exactly why it’s brilliant. by @mostlynerdless.de and @lutskedev.bsky.social What does JDK 26 bring? Watch the teaser of their talk 👇 www.youtube.com/watch?v=07ed... #java #vdams26

Java 26 is here, but it's boring. Nothing really exciting. But that's a good thing, as the boring stability is what made Java successful (co-written with @lutskedev.bsky.social): mostlynerdless.de/blog/2026/03...

Ready for another @apeldoornjug.bsky.social meetup tonight! Thanks to @craftsmennl.bsky.social for sponsoring!

700+ days of #Duolingo and I celebrated the only logical way: with cake 🎂🦉 Fully homemade. Slightly wobbly. Very proud 💚 Turns out small daily steps can end in chocolate 🍫✨

I need your help: If anyone wants to send me an audio snippet saying "Boring" (as in "Java 26 is stable. It's boring."), I would happily accept them. I want to play this audio via a button press during a talk. In other news: I'm speaking at @amsterdam.voxxeddays.com with @lutskedev.bsky.social.
