Full list of locations: https://www.awsgameday.eu/ "So... what actually IS a Community GameDay?" A GameDay is a hands-on, team-based challenge where you solve real AWS scenarios under time pressure. No slides. No lectures. You and your team get dropped into a live AWS environment, and things start breaking. Your job? Fix them. Fast. Think escape room meets cloud engineering. AWS put together a short [video](https://drive.google.com/file/d/1GJyaTUlZWu21ladTlWp13RZCesTeFZCs/view?usp=drive_link) that shows what a GameDay looks like in action -- hit play and see for yourself. Collaborate. Have fun. #AWS #Sarajevo #AWSCommunityGameDay #AWSCommunityEurope #AWSUserGroup #CloudTechnologies

This session explores the world of Power BI model types, focusing on the differences between Import, DirectQuery, and Composite models. We examine the limitations, advantages, and requirements of each model to provide a clear decision guideline for when to use each one. This session aims Power BI developers, data analysts, BI architects, and anyone interested in maximizing the efficiency and flexibility of their Power BI solutions. By the end of this session, atttendees will * know the main differences between Import, DirectQuery and Composit models * be able to choose (wisely) the right model for a given task * understand the impact on report design, user experience and governance If you want to avoid classic model type mishaps, this session is for you. Make your users (and database admins) happy and choose wisely!

**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Jonathan Stevens **Polymorphic Association - The Good, the Bad and the Ugly** When Active Record works, it’s great. Polymorphic associations in Active Record promise elegant flexibility: one interface, many possible models. When they work, they feel almost magical. But when your application grows and real‑world complexity sets in, that magic can quickly turn into confusion, broken queries, and performance headaches. We’ll explore where polymorphic associations shine, where they silently introduce technical debt, and why even experienced Rails developers can end up wrestling with unscoped queries, tricky joins, and hard‑to‑optimize relationships. We’ll walk through real examples of tangled polymorphic logic—and more importantly, show practical strategies to refactor, untangle, or even avoid these pitfalls entirely. By the end, you’ll know when to reach for polymorphism, when to run away from it, and what to do when your complex query simply refuses to cooperate. **AGENDA:** * See updates to parking below * Doors open at 5:30, feel free to come and hang out before! * Official start of the meeting is at 6:30pm * After the meeting is done, we will go hang out at a nearby space in Bridge Park!
