🐣🎨 EASTER EGG PAINTING NIGHT @ LOO-BLAH-NAH 📅 Saturday, 4 April ⏰ From 20:00 📍 Pub LOO-BLAH-NAH Center Ljubljana — let’s do something a little different this Easter Saturday. 🥚 THE TRADITION In Slovenia, the week before Easter means one thing: pisanice. Painted eggs. Passed down through generations. Every family has their own style, their own colors, their own way of doing it. We’re keeping the tradition alive — just without the boiled eggs, the vinegar, the wax, and the inevitable mess. 🎨 HOW IT WORKS You get 5 plastic eggs and a set of permanent markers. That’s it. No paint spills. No drying time. No broken shells on the floor. Just you, your creativity, and a blank canvas. Try different styles on each egg: 🎨 Minimal — one bold stripe, a single dot, geometric 🎨 Patterns — stripes, polka dots, details 🎨 Funny — faces, memes, chaos 🎨 Creative — abstract, traditional, weird 🎨 Your signature — make it yours No art skills required. 👉 The only rule: make it yours. ⚠️ IMPORTANT 👉 Egg painting is optional You can also: 🍻 just come for drinks 🤝 socialize 🎉 enjoy the atmosphere While others paint. 📊 SIGN UP (HELPS US PREPARE) To know how many eggs & materials to prepare: 👉 https://docs.google.com/forms/d/e/1FAIpQLSePmEgzcRs0XD5do3uxWEW2USO8lM9Vz_EI2HMIainNa5DaEQ/viewform?usp=publish-editor Takes 30 seconds. 🎯 THE IDEA This is about: • meeting new people while doing something fun • having an easy icebreaker activity • creating something small you can keep or gift 🌍 EXPECT • international + local crowd • relaxed, open atmosphere • easy conversations • spontaneous interactions 👉 come solo — you won’t stay solo 💸 PRICE 👉 \~5€ per person (includes 5 eggs + materials) ⏰ FLOW OF THE NIGHT 20:00–22:00 Egg painting + socializing 22:00+ Music, drinks, and transition into a full Saturday night 🌎 HOSTED BY Ljubljana International × Pub LOO-BLAH-NAH Powered by Ljubljana International — the biggest international community in Ljubljana (1000+ members): • weekly events • active WhatsApp community • locals + expats + Erasmus + travelers 👉 come once — leave with new people in your life 📲 JOIN THE COMMUNITY 👉 https://chat.whatsapp.com/KB3YaX1GuqY4eYcYUh3TpK 👉 https://linktr.ee/ljubljanainternational ⚡ FINAL 🐣 Come paint 🎨 Get creative 🍻 Or just come for the vibe Either way — this is where your Saturday starts.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
