🇫🇷 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 ☕🥐

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.

A practical session on integrating AI models into Java projects — and making it useful, not just impressive.

Had burritos, swapped culture stories, and ended up singing “Stairway to Heaven” with a room full of Java devs. Not your average @jugnoord.bsky.social night.
Shout-out to @rijosam.com & @hanno.codes for the laughs, lessons, and live music. 💙🎸

Hanno Embregts playing guitar. In front of him is a music standard for the microphone and a high table with an apple laptop on it. Behind him is a big screen with a cool photo that was taking during his key note at Devoxx Belgium a couple years ago. On the left you see some attendees from the JUGNoord event in the DUO building.
