Hello to all! I’m happy to announce our next monthly meetup will take place at **MaMa** (Preradovićeva 18) on **Monday, April 20th**, starting at **6 PM.** We’ve got two interesting talks, and afterward, we’ll head over to **"Old Pharmacy Pub"** (Andrije Hebranga 11) for some networking, so stay with us! \*\*\* **Declarative Generative UI: Schema-Constrained Dashboards Your AI Can't Break** by Vladimir Adamić In 2026 users expect to configure your platform with a prompt. But if you're a platform owner, letting an AI generate arbitrary UI is a non-starter — you can't guarantee branding, correctness, or security. In this talk I'll show you **Declarative Generative UI**: a pattern where an AI agent generates a JSON component tree constrained by a strict schema, and a renderer maps it to predefined React components. The AI picks the layout and wires the data — but it can only use building blocks you've approved. I'll do a live code walkthrough of an open-source observability platform (@kopai/app) that uses this approach in production. We'll trace the full pipeline: Zod catalog → JSON Schema → agent prompt → generated tree → recursive React renderer. We'll look at what works, where it breaks, and how agent skills and schema versioning help make it robust. You'll walk away with a pattern you can apply to any platform that needs AI-configurable UI without giving up control. **Finally fullstack react** by Fran Zekan TBA Happy to see you all at MaMa!

**Stress** is one of the greatest challenges of modern life. When stress becomes long-lasting, it can quietly turn into anxiety, affecting both mental and physical well-being and increasing the risk of more serious health issues. Through regular **mental hygiene**, we can gently influence our bodies and restore balance. **Autogenic training** is a method that uses focused attention and deep relaxation to reconnect the brain and the body. By activating the natural power of the mind, it helps release stress, anxiety, anger, and fatigue, while supporting concentration and memory. By restoring communication between the brain and the body, autogenic training supports overall health, balance and inner stability. Your donation for this event supports the work of our Club.

Zagreb language and culture exchange meetup. Chat in many languages, meet new people and plan adventures together. Hey everyone! 👋 As spring arrives in Zagreb and the city wakes up again, we’re keeping Thursdays social with **Small Friday International Zagreb** ([SFIZ.FUN](https://sites.google.com/view/smallfridayinternationalzagreb/)) a relaxed international meetup where locals, expats, Erasmus students and travellers gather to chat, exchange languages, share stories and plan the next adventure. Think of it as Zagreb’s global living room with lively conversations, and that moment when a random Thursday evening decides to surprise you. ✨ Whether you’ve just arrived in Zagreb, been here a while, or live around the corner, you’re very welcome. 📍 **When & Where** 📍 **The Beertija** Pavla Hatza 16, Zagreb 🕗 **Every other Thursday from 8PM** ✨ Free to join: simply grab a drink and support our host bar 🍺🎸 ✨ Open to everyone: all ages, backgrounds and language levels 💬 **What Happens at [SFIZ.FUN](https://sites.google.com/view/smallfridayinternationalzagreb/)**? Expect a relaxed, social atmosphere where conversations flow naturally. 🗣️ La**nguage Exchange** English, Croatian, Spanish, French, German, Italian, Ukrainian, Russian… and often more. 🌍 **Cultural Exchange** Locals, expats, travellers and Erasmus students sharing stories, experiences and perspectives. 🤝 **New Connections** Real conversations, genuine laughs, and the occasional new friend. 📅 **Weekend Planning** People often end up planning hikes, concerts, trips, festivals or nights out together. No formal structure, no pressure, just people meeting people. 🌸 **Why Join in Spring?** Spring is when Zagreb truly comes alive. Magnolia trees bloom across the city, café terraces fill with conversation, and longer sunny days invite people outdoors. Locals stroll through parks, cycle along the Sava, run around Jarun and Bundek lakes, or escape to the nearby Medvednica mountain for hikes and views above the city. At the same time, Zagreb’s cultural calendar blossoms with exhibitions, concerts, festivals and theatre performances, while markets like Dolac overflow with seasonal produce: asparagus, wild garlic, strawberries and fresh flavours of the season. It’s the perfect time to meet people and explore the city together. And many of those plans begin right here, at [SFIZ.FUN](https://sites.google.com/view/smallfridayinternationalzagreb/). 🌍 🍺 **Why The Beertija?** Because it’s more than a bar, it’s our headquarters. Expect: 🌿 leafy terrace vibes 🎸 rock-inspired atmosphere 🍺 excellent beers 🛋️ relaxed living-room energy 🚭 non-smoking indoor space It’s the kind of place where you pop in for one drink and suddenly realise the evening flew by. 💡 **First-Timer Tip** If it’s your first time: 👋 arrive early 🙂 smile and say hello 💬 jump into a conversation Everyone was new once and that’s how all starts. 🌍 **Join the Crew** [SFIZ.FUN](https://sites.google.com/view/smallfridayinternationalzagreb/) is a community built by the people who show up. So if your Thursday evening could use a little more conversation, laughter and international energy, come by and join us. Bring a friend if you like, or come solo and meet new ones. ✨Ditch the screen, grab a drink, meet the world🌍 See you on Small Friday! 🍻 **SFIZ Crew** P.S. Spread the word https://sites.google.com/view/smallfridayinternationalzagreb 🔎 **How to Spot Us** New here?

Hello Rubyists! This month we're going for something completely different! Well, not really, it's still Ruby related, but it's unlike the other meetups. We'll do a pub style Ruby trivia quiz! A big thank you to [RubyCentral](https://rubycentral.org), in partnership with [GitHub](https://github.com), for making this event possible and for graciously covering the cost of the venue. Their support helps us keep events like this going. After the talks, we'll keep the evening going with the unofficial part of the meetup at the nearby cafe, so stick around for a drink and continue the conversation. See you at BIZkoshnica! \*\*\* **A Ruby Quiz!** by Radan with help from Bruno and Stanko Radan has been testing some AI skills and has spun up a Rails live quiz app just for this occasion. Together with Bruno and Stanko he's preparing weird Ruby questions for the quiz. The app might have been implemented with help from AI but this quiz is for you, no AI assistance allowed! The correct answers will be briefly explained in between questions so you might also learn something.

Hallo liebe Java User Group Mitglieder! Diesmal haben wir Nils Hartmann mit seinem Talk zum Thema "**[Spring Modulith](https://spring.io/projects/spring-modulith)**" zu Gast. Wir freuen uns euch zu sehen (virtuell oder vor Ort). * 18:00 Uhr: Einlass * 18:30 Uhr: Talk * ab 19:30: Ausklang des Abends Dank an [qSkills](https://qskills.de/) für Location, Bier und Pizza! \-\-\- Oft sollen Anwendungen in entkoppelten Modulen entwickelt werden, um Ordnung und Struktur in unseren Code zu bekommen und darüber Wartbarkeit zu garantieren. Microservices stellen dafür einen sehr konsequenten Ansatz dar, können aber auch eine hohe Komplexität mit sich bringen. “Monolithen” hingen sind vergleichsweise bequem in der Entwicklung, stehen aber im Verdacht, schnell zu einem unübersichtlichen “Big Ball of Mud” zu werden. Diesem Problem versucht “Spring Modulith” entgegenzutreten. Damit werden Spring Boot-Anwendungen in einer gemeinsamen Codebasis entwickelt (”monolithisch”), innerhalb dieser werden aber Module definiert ("modulitisch"), deren korrekte Verwendung anhand von Architekturregeln kontinuierlich überprüft und sichergestellt wird. Außerdem erweitert Spring Modulith das Spring-eigene Eventsystem, um auch zur Laufzeit für eine Entkopplung der Module zu sorgen. In diesem Live-Coding-Vortrag möchte ich anhand praxisnaher Beispiele eine Einführung in Spring Modulith geben und mit euch diskutieren, welche Konsequenzen sich für unsere Anwendungen daraus ergeben und für welche Szenarien dieser Ansatz besonders geeignet ist. \-\-\- Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten?
