It starts with a small chatbot named Leo.
Then it grows, and suddenly everything is fragile & hard to change.

Java 26 is “boring.” And that’s exactly why it’s brilliant.

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):

Lutske de Leeuw in a pink T-shirt smiling with a green duolingo cake. It has green frosting on the outside with a fondant duolingo owl on top. The cake stands on a table and in the background you see an office space.
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.

Thanks for being part of my year!
A Sinterklaas treat with kruidnoten, chocolate kruidnoten and more chocolate wrapped in foil with a red ribbon on a grey background.
Got a Sinterklaas treat box from work ( @craftsmennl.bsky.social ) today 🎁✨
Sinterklaas has always been my favourite holiday, so this absolutely made my day.
Chocolates at the office? Yes please 🍫😄
Anyone else get something fun from their employer this Sinterklaas season? 🎅✨
Trying to catch up on this year’s #CraftingAIAdventOfPrompt already behind, whoops 😅
But today I added a new friend to the scene: a cheerful Christmas-ready lion joining Hugo and Chipper in their cozy countdown corner.
Loving how these little AI-generated characters come to life! 🎄🦁✨
🇫🇷 Bonjour from #NewCrafts Paris!
AI and GenAI are cool, but today I’m taking it back to basics. Machine Learning 101 (with a few cats included 🐱).
Let’s talk code, coffee, and croissants ☕🥐
“Java is here to stay — maybe forever, or at least our lifespan.” .
In her chat with Andres Almiray, Lutske de Leeuw shows how Java developers can make AI their own, with tools like LangChain4j and a strong community backbone.

Arrived at jspring @nljug.bsky.social Do I see you there (during my session)?
A blurry photo of Lutske de Leeuw and the audience during JNation 2025. Everybody is smiling and raising or waving their hand to be in the picture.
Lutske de Leeuw raises her hand to ask the audience to answer the question on the screen. During her Jnation talk "Tame your llama, get AI in Java" The room is light and you see the audience listening carefully with every seat is taken.
Lutske de Leeuw smiling and doing thumbs up just before the presentation in a green dress behind her stickered laptop and the JNation stand with an owl with a rock guitar. In the back you see a Jnation flag and a part of the big screen.
Had an amazing time at @jnationconf.bsky.social! Met so many inspiring people, learned a ton, and shared stories about AI in Java. Thanks to everyone who made it unforgettable. See you next time!
