⚡ **AI & Coffee — Luxembourg's In-Person AI Community** AI is moving faster than any of us can keep up with alone. The best way to make sense of it — and stay ahead of it — is by getting in the same room as people who are just as obsessed with it as you are. That is exactly what AI & Coffee is about. We are bringing together Luxembourg's most curious, creative and driven minds for an afternoon of open, honest and energising conversations about artificial intelligence — not in theory, but in practice. No slides. No pitches. No pressure. Just real people, real ideas and real connections over great coffee. ☕🤖 *** 📅 **Sunday 3 May \| 15:00 – 17:00** 📍 **Chiche,** 20 avenue pasteur, 2310 Limpersberg *** ☕ **What we will talk about** AI & Coffee is an open conversation — guided by curiosity and driven by the people in the room. Expect discussions around: * What is actually happening in AI right now — the real breakthroughs, the real hype * Tools, projects and experiments people are building and testing * Practical AI use cases across industries — finance, marketing, tech, healthcare and more * Ideas, feedback and fresh perspectives from people at different stages of their AI journey Feel free to bring your laptop if you want to show something you are working on. Some of the best conversations at our last event started with someone sharing their screen. 💡 *** 👥 **Who is this for?** Developers and engineers building with AI Founders and entrepreneurs exploring AI for their business Investors and mentors looking to understand what is coming Researchers and students at the forefront of AI Creatives experimenting with AI tools Corporate professionals curious about AI's impact on their industry And anyone who simply cannot stop thinking about where AI is heading If AI excites, challenges or intrigues you — you belong here. *** ✨ **What to expect** A warm, welcoming and relaxed atmosphere where everyone has a seat at the table. Our host will kick things off with a few conversation sparks and the latest AI highlights — then the rest is yours. Meet, talk, connect and exchange freely. No commitment. No agenda. No pressure. Just the kind of afternoon that leaves you energised, inspired and already looking forward to the next one. *** 🎉 **The only cost is your own coffee or drink.** Bring your curiosity, your ideas and an open mind — and let's keep building one of the most exciting AI communities in Luxembourg. 🇱🇺 👉 Register now — spots are limited and they go fast!

Hi All, Some of you might have seen in the city centre the Märtchen ([https://www.vdl.lu/en/visiting/leisure-and-recreation/luxembourg-city-markets/maertchen](https://www.vdl.lu/en/visiting/leisure-and-recreation/luxembourg-city-markets/maertchen)). Apparently it's linked to some religious event (Christian, not foody). But don't ask me. Anyway, I thought about finishing a hike there. We start in Howald near the tram stop Scillas, go to the Alzette and walk along to the city centre. With some water breaks. So the trail will be mostly flat forest with some stairs for the conscious. Start: Tram Stop Scillas / Tennis Howald Destination: Märtchen on Knuedler Lunchbreak: Märtchen on Kuedler Public Transport: Tram to Scillas Parking: I suggest to park in the city centre Questions? Hope to see many of you on Sunday Jörg Disclaimer: The hike is at your own risk. Come prepared (water, sun cream, shoes, smile...). Know your limits. Don't hesitate to ask if you have any questions.

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.

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

**Abstract:** This is a practical playbook for building a production-grade data lakehouse. It walks through foundational principles — naming conventions, least-privilege access, automated CI/CD testing — before diving into medallion architecture. Furthermore, metadata-driven design patterns show how configuration tables and dynamic notebook orchestration eliminates hard-coded pipelines. The deck covers star schema modeling, guidance on choosing between Spark, Pandas, and SQL, and data quality enforcement using DQX with YAML data contracts. Finally, we dive into security best practices and performance optimizations. **Host:** Justin Shea, Mehdi Jeddi, Erik Pak, and Sou-Cheng Choi **Talk Format:** This is a hybrid event.
