🌸Turn Thursday into Small Friday: Zagreb’s International Meetup🌍
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/)**?
Expect a relaxed, social atmosphere where conversations flow naturally.
🗣️ La**nguage Exchange**
English, Croatian, Spanish, French, German, Italian, Ukrainian, Russian… and often more.
🌍 **Cultural Exchange**
Locals, expats, travellers and Erasmus students sharing stories, experiences and perspectives.
🤝 **New Connections**
Real conversations, genuine laughs, and the occasional new friend.
📅 **Weekend Planning**
People often end up planning hikes, concerts, trips, festivals or nights out together.
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.
So if your Thursday evening could use a little more conversation, laughter and international energy, come by and join us.
Bring a friend if you like, or come solo and meet new ones.
✨Ditch the screen, grab a drink, meet the world🌍
See you on Small Friday! 🍻
**SFIZ Crew**
P.S. Spread the word

🔎 **How to Spot Us**
New here? Best trick is to swing by right at the start, that’s when it’s easiest to find the crew and jump straight in, or ask the bar staff about the event ✨

Peter Kranz: Enter the Java Dungeon - Eine interaktive Reise durch Java 9-26
Hallo liebe Java User Group Mitglieder!
Diesmal haben wir Peter Kranz mit seinem interaktiven Talk zu den unterschiedlichen Java-Versionen zu Gast.
Wir freuen uns euch zu sehen (virtuell oder vor Ort).
* 18:00 Uhr: Einlass
* 18:30 Uhr: Talk
* ab 19:30: Ausklang des Abends
Dank an [adesso](https://www.adesso.de/de/unternehmen/standorte/nuernberg.jsp) für Location, Bier und Pizza!

Java entwickelt sich seit Version 9 im Halbjahresrhythmus weiter – mit Records, Pattern Matching, Virtual Threads und vielen weiteren Features. Doch wer hat schon die Zeit, 17 Releases im Detail zu verfolgen? Die Fülle an Neuerungen ist enorm, und je nach Projekt und Interesse sind ganz unterschiedliche Features relevant. Ein klassischer Vortrag kann hier nur einen starren Pfad durch die Feature-Landschaft bieten.
Dieser Talk geht einen anderen Weg: als interaktiver Dungeon Crawler. Das Publikum entscheidet gemeinsam, welchen Themenkomplex es als Nächstes erkunden will – Moderne Sprach-Features, Concurrency, APIs, JVM-Tooling oder experimentelle Preview-Features. Jede Entscheidung führt tiefer in den Dungeon und schaltet neue Level frei. So entsteht bei jedem Vortrag ein einzigartiger Pfad durch die Java-Versionen 9 bis 26.
Wie in einem echten Dungeon Crawler sammelt das Publikum dabei XP und wird am Ende einer Klasse zugeordnet – vom Warrior mit Fokus auf Performance bis zum Wizard der Sprach-Features. Ob Einsteiger:in oder erfahrene:r Entwickler:in: Jede Session liefert praxisnahe Einblicke in genau die Java-Features, die das Publikum am meisten interessieren. Kein Vortrag gleicht dem anderen – und der einzige Weg, alles zu sehen, ist wiederzukommen.

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
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.

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.
CBusData - Practical AI for Power BI Developers
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.
