Most language exchanges are built around **movement**. —fast rotations, brief chats, surface-level conversation. New table. New person. Start again. It feels productive. It isn’t. Real conversations don’t happen in 10 minutes. They start there. Then they get interesting. At Flip Lingoes, **you stay.** Same table. Same group. Enough time for real conversation and real connection, beyond the surface level. Every 5 minutes, you switch roles: **fluent speaker ↔ learner**, not people. Before you arrive, **[create a profile here](https://www.fliplingoes.com/language-exchange-dublin/)**[,](https://www.fliplingoes.com/language-exchange-dublin/) tell us what language you're learning. This helps our **automated matching algorithm** put you in the right small group. No awkward searching. No guesswork. Simply scan the QR code on arrival and it automatically matches you with fluent speakers of your target language. We host events at Zanzibar Locke: calm, well-designed, easy to hear, easy to focus. *** **Event Flow** 6:45–7:15 → Seamless check-in (QR code, get matched, sit down) 7:15–8:30 → Language Exchange (structured, focused) 8:30 → Optional social + snacks included **Crispy chicken wings.

## Details The title of the event is a paradox! Read in silence and then discuss with like-minded folks! :-) 📝 **How does this work?** We will meet in the Bartley's Restaurant area from 7:00 PM to 8:15 PM for silent reading and followed up by discussion. **During silent reading, you're expected to remain silent and read.** Please bring your headphones and refrain from the discussion during the first one hour in the area. 👥 **Socialising** After an hour, at 8:15 PM, we'll discuss and socialize about the book you're reading. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! Feel free to join at any point during the event. The event is indoors, hopefully, we can continue the tradition of the silent reading in the winter! **📌 Helpful Tips and Notes** * Bring headphones to block out surrounding noise * I will post a comment on the event page when I arrive to indicate where we're seated, so everyone can find us * If you prefer to skip the silent reading, you can join directly at the bar at 8:15 PM ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. It may be small but don't hesitate to reach out to me. Looking forward to meeting you all 😊

**[Early Bird Discount](www.eventbrite.com/e/1987332173027/?discount=Meetup)** ### ✨ What Is the Social Pub Crawl? A relaxed and social pub crawl designed to help people connect naturally while enjoying a night out in Dublin. This is **not a massive party crawl** and not a tourist tour. It’s a friendly, international experience where drinks, short social games and good conversations come together in an easy and natural way. Whether you come alone or with friends, you’ll quickly feel part of the group. ### 🍻 How It Works We’ll visit several pubs in the city centre, staying around **30–40 minutes in each one**. At every stop, the organizer will run a **short and simple social activity**. These games are designed to: * Break the ice naturally * Help people interact without pressure * Work well in busy, noisy pubs Between activities, there’s plenty of time to chat, grab a drink and enjoy the atmosphere. 🏆 In each activity, points are awarded to several participants. At the end of the night, **the 3 people with the most points win a free drink**. ### 🍀 Who Is This Event For? Absolutely everyone. New in Dublin, long-time residents, expats, locals, shy people, outgoing people — all are welcome. You don’t need to drink alcohol, be loud, or be “good at games”. The only requirement is being open to meeting new people in a relaxed way. ### 💬 A Friendly & Comfortable Atmosphere Our events are known for being inclusive, respectful and easy-going. Come alone or with friends — you’ll feel comfortable from the very beginning. To keep the experience social and personal, **spots are limited**. ### 🕕 Practical Details • **Time:** 19:00 – 22:30 • **Group size:** Limited • **Location:** In front of the Odeon!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

We will show how to build custom agents with Microsoft Agent Framework. Attendees will learn how to build and custom host agents when Microsoft Foundry is not a viable option.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
