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.

This workshop will be held in a hybrid format, allowing you to participate either in person or virtually. ‼️ To help us prepare, please ensure you have registered correctly here : https://gdg.community.dev/events/details/google-gdg-krakow-presents-build-with-ai-4-production-ready-ai-agents-hybrid-workshop/ and selected your attendance preference: **In-Person**: Join us on-site at **EPAM HUB Krakow.** **Online:** Join us via the meeting link: https://meet.google.com/yro-fdxs-qzw Please use **personal gmail account** for registration.

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.

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? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

Ciao a tutt\*! Let's meet Monday at 6.30pm at the Upper Arlington Library (Tremont Branch) in **Meeting Room A** to speak in Italian for 1 hour.

Join us as we get together to see the BAFTA-winning British biographical dark-comedy/drama, I SWEAR! The film is based on the true-life story of a Scottish man diagnosed with Tourette’s syndrome at an early age. Here are details, a trailer and our plan for this event: DESCRIPITON: This true-life story follows a Scottish man diagnosed with Tourette's at 15. Targeted as 'insane' by his peers, he struggled with a condition few had witnessed. In search of his life’s purpose, he began campaigning for better understanding and acceptance of the condition of Tourette's as an adult. The film is written/directed/produced by Kirk Jones and stars Robert Aramayo, Maxine Peake, Shirley Henderson and Peter Mullan. TRAILER: https://www.youtube.com/watch?v=oeWqQN3snCU BUZZ & ACCLAIM: I Swear currently has an incredible 100% positive rating on Rotten Tomatoes, which says: “A deft balance of prickly and sweet that's bound together by Robert Aramayo's knockout performance, I Swear doesn't sugarcoat the challenges of Tourette syndrome while delivering an uplifting tale of resilience.” Others call it, “"funny, fierce and full of heart!” The film was released earlier in the UK making it eligible for this year’s BAFTA’s where it won Best Casting and Best Lead Actor for Robert Aramayo. The film and Robert Aramayo's performance will be eligible for next year’s Oscars! PLAN: We’ll plan for a 7pm-ish showing and will meet in the bar area about 30 minutes before showtime! Once details are confirmed, advance ticket purchase is advised! Details will be confirmed/announced as the date gets closer. Should be a good one, Dan

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!
