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/)**?

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.

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!

We have never until now featured Zinfandel, the ubiquitous California grape with the Dublin Wine MeetUp Group. At its best Zinfandel, is rich, voluptuous, with great depth of red and blue fruits. Jammy and hedonistic are common descriptions Each person should bring one bottle of an quality Zinfandel wine; be creative and quality conscious, with some bottle age if possible. Turley, Martinelli, Biale, Seghesio, Ridge, Hartford Bedrock, Carlisle, Klinker Brick, Frog's Leap, and anything from the Rockpile vineyard is likely to be very good to great. The Prisoner wines began as a Zinfandel blend. Also bring a protein based appetizer to share and **a wine glass for your personal use.** Cheese and meats are best with these wines. There will be a gas grill behind the clubhouse to grill. We’ll gather at the Oak Creek clubhouse, where the Dublin Wine Group, hosted by Thom and supported by Timothy, will take it from there. Come join us for a fantastic mix of great wine, food, and even better company!

**History** [Prairie Oaks Metro Park](https://www.metroparks.net/parks-and-trails/prairie-oaks/) sits along the Franklin and Madison County border, west of Columbus near areas like Hilliard and West Jefferson. The land was part of the broader push in the late 1990s and early 2000s to expand the Metro Parks system into the northwest and western quadrants of the county. Metro Parks began acquiring parcels for what would become Prairie Oaks during the millennium era, as part of a wave of new parks aimed at protecting natural features around Big Darby Creek. Much of the property had been altered by past uses, including farming and quarrying, which left behind pits that later became the Darby Bend Lakes. The park's creation reflected growing interest in preserving remnants of the Darby Plains ecosystem, one of Ohio's original prairie regions that had largely disappeared after European settlement. The park officially opened to the public in 2000, making it one of the newer additions to the Metro Parks lineup at the time. As the 12th park in the system, it joined others acquired around the turn of the century, like Glacier Ridge. Initial access focused on basic trails and the scenic Big Darby Creek, a State and National Scenic River that winds through the property. Restoration efforts kicked off soon after opening, with crews using seeds native to the Darby Plains to replant nearly 500 acres of tallgrass prairie and grasslands. These plantings aimed to revive the open oak savannas that once characterized the area before widespread agriculture in the 1800s. Over the first decade, Prairie Oaks grew in popularity for its mix of restored habitats and recreational features. The former quarry in the eastern section transformed into the Darby Bend Lakes area, where four connected lakes now offer boating, fishing, and a dedicated dog swim spot. Trails expanded to showcase the prairie blooms, especially in summer and fall when asters and goldenrods light up the fields. Partnerships with groups like The Nature Conservancy highlighted the park's role in protecting the Darby Creek watershed, often called one of the "Last Great Places" for its water quality and biodiversity. Visitors from around central Ohio started discovering it as a quieter alternative to busier spots closer in. Restoration work continued into the 2010s, including wet prairie projects on about 190 acres to enhance hydrology and native plant diversity. The park's size reached over 2,200 acres, incorporating more floodplain along Big Darby Creek for flood storage and wildlife habitat. Amenities like parking at Sycamore Plains and Darby Bend Lakes improved access, drawing hikers, kayakers, and birders. Events and programs began emphasizing the prairie theme, from guided walks on blooming seasons to educational talks about pre-settlement landscapes. These efforts helped solidify Prairie Oaks as a showcase for ecological recovery in the Metro Parks system. Today, Prairie Oaks stands out for blending restored prairie with creek-side adventure, just a short drive from the west side. Its history mirrors the Metro Parks' shift toward large-scale habitat restoration in the 21st century. The park continues to evolve with ongoing stewardship, protecting what remains of the Darby Plains while offering locals a place to experience tallgrass vistas and oak openings. Whether paddling the lakes or walking the trails, it's a reminder of how much the region has changed since settlement — and how intentional work can bring some of it back. **Map of the Park** Here is a [map of Prairie Oaks](https://www.metroparks.net/wp-content/uploads/2021/10/POK_map_1980.jpg). **Summary** For this event, we will hike the Coneflower, Alder, and Sycamore Plains Trails, and, depending on conditions, the Osage Opening and Tall Grass Trails, or Lake View, Mound, Darby Creek Greenway, and River Rock Trails around the lakes. Either way, we'll go around 4.5 to 5 miles. For the most part, this won't be a terribly strenuous hike; Prairie Oaks tends to be flat. However, some of the hike won't be shaded, so be prepared for the possibility of some sun. Parts of the trails may also be muddy or wet, so I recommend [hiking shoes](https://www.amazon.com/dp/B0D972KN3W) and a change of socks. **Where We'll Meet** * Enter the Park at the main entrance at 3225 NE Plain City-Georgesville Rd. If you put "Prairie Oaks Metro Parks" into your Google Maps, it should default to this main address (but double-check to be sure). * After you enter the Park, the first parking lot on your right is the Park Office. Keep driving past this lot. * Enter the second parking lot you come to (which is also on your right). There's a picnic area, playground, and latrine here. There's no water fountain, though, so I recommend you bring water of your own, at least for after the hike. * I've included a screen shot in the Photos, below, where I've circled in blue the main Park entrance as well as the picnic area we're meeting at. **After the Hike** After we're done surveying the prairie grasses, we'll head over to [Crooked Can Brewing](https://crookedcanohio.com/) for [drinks](https://www.crookedcanohio.com/beer) and [food](https://www.crookedcanohio.com/center-street-market). The brewery has an entire food court, and they have a large free parking lot next to the [Early Television Museum](https://www.earlytelevision.org/). The actual address of the brewery is [5354 Center St, Hilliard, OH 43026](https://www.google.com/maps/place/5354+Center+St,+Hilliard,+OH+43026/data=!4m2!3m1!1s0x883893f9ede6d5fb:0xbecf42d7055d9006?sa=X&ved=1t:242&ictx=111). We should be there by 5 if you can't make the hike and just want to join us for drinks.
