Hello Rubyists! This month, we're turning our attention to AI and the many ways it's already changing how we work and build with Ruby and Rails. Our meetup will have 3 shorter talks so we can get more perspectives how different developers and companies use AI. 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! \*\*\* **Keeping AI Agents in a Sandbox** by [Marko Avlijaš](https://www.linkedin.com/in/marko-avlijas/) This talk is about building a safer environment for AI agents. Since an LLM agent cannot be fully trusted, the goal is to limit what it can access and what damage it can do. The agent runs inside a Firecracker microVM and a Podman container, with access only to approved data and services. The talk will also give a simple overview of isolation in containers and virtual machines. It will cover the basic ideas behind namespaces and cgroups, touch on past escape vulnerabilities, and explain how auditing can help detect suspicious behavior. **To vibe, or not to vibe, is that the question?!** by [Iskren Nemet](https://www.linkedin.com/in/izkreny/) As it is almost impossible to hide from the AI tsunami, what can you do if you actually want to learn fundamental and advanced programming techniques, and not just be another AI agent shepherd? Let's pair up with Socrates and examine together what options are on the table and how we can use them inside our Ruby and Rails world via VS Code, the most standard and popular code editor today, and its AI fellow: GitHub Copilot. **Wanna upgrade your agent flow?** by [Fran Zekan](https://www.linkedin.com/in/zekan/) We all probably tried some form of Copilot AI autocomplete, most of us probably at least tried agents. But what about those mythical "10/20/50x speed improvements"? How do you "spend $1000+ in token in a month"?. "How is this actually helping you"? The goal of this talk is to show a couple of tricks / hacks for how to use agents to work *smarter.*

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/)**?

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.

Netko je jednom rekao - jedini pravi programeri su matematičari i fizičari - pa nas programere veseli ugostiti Antoniju Capan profesoricu savjetnicu matematike, Zrinku Tomašković, profesoricu matematike i Josipa Karasa, profesora fizike. **STEM obrazovanje** sve je važnije za razvoj vještina potrebnih u svijetu koji se brzo mijenja. No kako ono izgleda u praksi – *u učionicama, projektima i radu s učenicima*? Od Antonije Capan ćemo iz prve ruke naučiti o aktivnostima karlovačkih nastavnika koji koriste integrirani pristup učenju kroz praktične projekte, učenju rješavanjem stvarnih problema i kreativnom radu s učenicima, kakvi se STEM projekti provode u karlovačkim školama, koje se digitalne i edukacijske alate koristi u nastavi i koje dobre prakse potiču kritičko razmišljanje i samostalno istraživanje učenika. Antonija je s kolegicama i kolegama pokrenula i *StemKA konferenciju*, koja u Karlovac dovodi izvrsne predavače i primjere inovativnog rada u obrazovanju. Govorit ćemo i o iskustvu organiziranja takvog događaja te o tome kako se oko STEM-a gradi lokalna zajednica. U predavanju će se također osvrnuti na aktualna istraživanja o stanju STEM obrazovanja, izazove poput nedostatka nastavnika te inicijative koje kroz rad udruga pokušavaju unaprijediti sustav. Razgovarat ćemo i o novom nastavnom kurikulumu povezanim s *umjetnom inteligencijom*, u čijoj izradi Antonija sudjeluje. Ako vas zanima kako izgleda **STEM obrazovanje iz prve ruke** – i kako možemo potaknuti nove generacije na *znanost, tehnologiju i kreativno razmišljanje* – **pridružite nam se**. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- Zrinka i Josip pozvat će nas u **“Kozmos na karlovački način”** i pokazati kako približiti *svemir* u učeničke klupe, te kako u praksi objašnjavaju *odnose planeta u Sunčevom sustavu*. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Antonija Capan** Magistra edukacije matematike, učitelj savjetnik u Osnovnoj školi Grabrik te predsjednica udruge stemKA - udruge za popularizaciju znanosti.

Hallo liebe Java User Group Mitglieder! Diesmal haben wir Thomas Künneth mit seinem Talk zum Thema "**Climbing the Codeberg - Some Developer's Thoughts on Leaving GitHub**" zu Gast. Wir freuen uns euch zu sehen (virtuell oder vor Ort). * 17:45 Uhr: Einlass * 18:15 Uhr: Talk * ab 19:00: Ausklang des Abends Dank an [codecamp:n](https://www.codecamp-n.com/) für Location, Bier und Pizza! \-\-\- As developers increasingly prioritize privacy, digital sovereignty, and true open-source values, many are questioning their reliance on corporate-owned platforms like GitHub. Enter Codeberg—a community-driven, non-profit Git hosting platform funded by donations and powered by Forgejo. But is the grass really greener, and how difficult is the transition? In "Climbing the Codeberg," we’ll explore both the philosophical motivations and the practical realities of leaving GitHub. Walking through a firsthand developer's journey, this talk will guide you through the process of establishing your code’s new home and taking back control of your workflow. In this session, we will cover: * The "Why": Understanding the fundamental differences in philosophy and legal structure between a corporate-owned giant and a non-profit, community-led alternative like Codeberg. * Safe Migration Strategies: Step-by-step insights on migrating repositories (including metadata like issues and releases), proving your identity via Mastodon, and utilizing "tombstoning" techniques to avoid critical security risks like namespace hijacking on your old GitHub account. * Restoring Automation: Leaving GitHub doesn't mean leaving CI/CD behind. We'll dive into leveling up your new environment by setting up local Codeberg Actions runners, exploring both containerized (Docker) approaches and host-level (act_runner) configurations for architectures like Apple Silicon. Whether you are ready to make the full leap to a community-owned forge or simply want to explore what true digital sovereignty looks like, this session will equip you with the tools, commands, and insights needed to successfully summit the Codeberg. \-\-\- 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!

Join us as we get together for a Discount Tuesday / Choose Your Movie event to see your choice of two great films! Option 1 is the dark comedy/drama based on a true story TOW! The film stars Rose Byrne as a homeless Seattle woman how battles a towing company. Option 2 is the off-the-rails, over-the-top, action-comedy-horror THEY WILL KILL YOU! The film stars Zazie Beetz as a woman who answers a help wanted ad to be a housekeeper in a mysterious New York City high-rise not knowing its mysterious past! Here are details, trailers and our plan for this event: TOW: This dark comedy/drama is based on a true story and follows a homeless Seattle woman who fights her way out of "tow-company hell" to reclaim the car that had held her life together after receiving a tow bill for $21,634. The film stars Rose Byrne, Ariana DeBose, Demi Lovato, Octavia Spencer, Dominic Sessa, Elsie Fisher and Simon Rex! The film premiered to solid reviews at last year’s Tribeca Film Festival where critics declared, “TOW is a winner!” It’s “a story of perseverance, heart, and real fight, the kind of small human story we see less frequently these days, but need now more than ever.” TRAILER: https://www.youtube.com/watch?v=qdkpcsuPAhA THEY WILL KILL YOU: A woman takes a job as a housekeeper in a NYC high-rise, unaware of the building's history of disappearances. She soon realizes the community is shrouded in mystery. The film is directed by Kirill Sokolov and Zadie Beetz, Myha'la, Paterson Joseph, Tom Felton, Heather Graham, and Patricia Arquette. The film is being released immediately following its premiere at this year’s SXSW Festival earlier this month. Early reviews say it’s “an adrenaline rush of action-packed fights, tons of blood and gore and plenty of laugh-out-loud moments” and a movie that’s “unafraid to march to its own campy, violent, and clever little drummer!” TRAILER: https://www.youtube.com/watch?v=XYqQPiXpi4w PLAN: Not exactly a “Choose Your Movie” event, more like an early show and a late one (or both if you’re feeling sparky)! \* If you’d like to see TOW, please purchase your ticket for the 5:00pm showing and meet in the upstairs lobby between 4:40 and 4:50pm! \* If you plan to see THEY WILL KILL YOU, please purchase your ticket for the 7:45pm showing and meet in the upstairs lobby between 7:25 and 7:35pm! \* Tickets for both films on sale now and advance purchase is advised! Tickets just $5.00 ($6.50 after online fees when purchased via the GFC website). Once you have yours, please list your movie of choice and seat number in the Comments section of this event. \* Also, as a reminder, close, convenient parking available in the nearby garage (Between 9th and 11th, just off High) and just $2 when you have your ticket validated at the theater! Look forward to seeing you there, Dan

Join us as we get together for an Arthouse Movie Friday event to see the A24 dark comedy /romance / psychological-thriller, THE DRAMA! The film stars Zendaya and Robert Pattinson as a happily engaged couple whose relationship is challenged when one discovers unsettling truths about the other. Here are details, a trailer and our plan for this event: DESCRIPTION: The film follows a happily engaged couple whose relationship is put to the test when an unexpected turn sends their wedding week off the rails. The film comes from A24, is written/directed by Kristoffer Borgli stars Zendaya, Robert Pattinson, Mamoudou Athie, Alana Haim, Hailey Gates and Zoë Winters. QUICK WORD OF WARNING: The film hasn’t screened for critics yet and most of the details are being kept tightly under wraps. But, early buzz (possibly promotional) says the film is a brilliant psychological thriller/romance but also provocative, twisty and some contains occasional uncomfortable viewing! I love the cast and trailer, so look forward to seeing for ourselves! ZENDAYA-PATTINSON TRIFECTA CHALLENGE: Robert Pattinson and Zendaya will star in THREE movies together this year, including THE DRAMA, Christopher Nolan’s THE ODYSSEY this Summer and Denis Villeneuve’s DUNE: PART THREE at Christmas! TRAILER: [https://www.youtube.com/watch?v=6zmKcUa4Xxk](https://www.youtube.com/watch?v=6zmKcUa4Xxk) PLAN: We’ll plan for 7pm-ish showing and will meet in the lobby area about 30 minutes before showtime! Advance ticket purchase not required for this theater but early arrival is advised. Possibly post-movie get-together at the nearby Rusty Bucket! Complete details will be confirmed/announced as the date gets closer. Take care and look forward to seeing you there, Dan

A fun way to compare wines from two different countries at a time. House Wine is squaring off two countries' wines against each other each Thursday in March. March 12, March 19, March 26, and the Finals April 2nd. Meet and Greet format....show up after 7pm, pay your $15 at the cash register, get your wine glass, and enjoy. I will get a table reserved for the group. Remember, you may bring in your own food or takeout. Attendance is your agreement to the Group's Waiver of Liability terms. See our Group homepage for details. Parking is tough at House Wine; there is a municipal lot one-half block north of the shop and sometimes parking at the lot behind Jet Pizza, accessed by the lane between the east House Wine parking lot and the residence to the east.

**Complex Trauma Support Group** Our group is intended for survivors of complex trauma. If you are here, it’s likely that so much of who you are and what you have experienced in this life is actually invisible to most people––to family, society, coworkers, and the people who are around you. We are a peer-led group of survivors creating opportunities for ourselves and others to share our experiences, share support, and build relationships in kind community together. Survivor experiences might include: child sexual abuse, incest, child trafficking, and other experiences of people living with traumatic dissociation and complex PTSD. **What to expect at your first meeting:** Currently, we are offering a bi-monthly in person group at 2:00pm on the first and third Sunday of the month. The only criterion for joining the group is that you are a survivor of trauma wishing to have more kindness in your own life and share kindness with others, and that you agree to practice to group’s relational agreements available for view here: https://www.kindgroups.com/agreements. Joining the group is free of charge. We ask that new people connect with us for 30 minutes on the phone or on zoom before coming to their first group, so that we can determine together that we are a good fit. Our meetings last approximately 90 minutes. Participants are never required to share. You’re also welcome to choose a pseudonym and you will never be asked for private information. You are welcome to leave at any time. The kindness that survivors can share when among others who have survived similar childhood experiences is something we rarely get to experience. Time spent with others who understand even a little bit more about us is a relief. Our hope is to help ourselves and others experience that we are not alone. We wish for our efforts to be a cause of kindness in our own lives and the lives of each other. You can read more about the groups at www.kindgroups.com.
