Join in with the latest Amsterdam JUG Meetup with the [GIGABITES Community](https://www.meetup.com/gigabites-just-eat-takeaway-com) at **Just Eat Takeaway.com (JET)**, at [Piet Heinkade 61, 1019 GM, Amsterdam](https://maps.app.goo.gl/a8vmLkhP7taSwPXH8). **Agenda** **18:00 -** Doors Open (And Food!), thanks JET! **18:30 - 19:30** Talk 1: **The JET** **Journey with Apache Flink -** [Behrooz Mirzaie](https://www.linkedin.com/in/behrooz-mirzaie/) (Tech Lead at JET) **19:30 - 19:45 Short Break** **19:45 - 20:45** Talk 2: **From Tables to Streams: Apache Flink for SQL Developers -** [Viktor Gamov](https://www.linkedin.com/in/vikgamov/) (Principal Developer Advocate at Confluent) **21:00 The End** **Abstracts** **Talk 1: The JET Journey with Apache Flink -** [Behrooz Mirzaie](https://www.linkedin.com/in/behrooz-mirzaie/) Our journey with Apache Flink at JET begins with the recognition that while Flink is powerful and that our primary job is to make that power approachable for everyone. This realization led us to consider "What If? Abstracting complexities" as part of our diagnosis. In this sesion, we will discuss how, ultimately, the core lesson we've learned is to hide the complexity, though not the capability, of the underlying system! **Talk 2: From Tables to Streams: Apache Flink for SQL Developers -** [Viktor Gamov](https://www.linkedin.com/in/vikgamov/) (Confluent) What if your SQL queries could process data as it happens instead of after it's stored? Apache Flink speaks SQL fluently, but it's not a database – think of it as a conductor orchestrating endless streams of data rather than a librarian managing stored records. This session bridges the gap between traditional SQL and stream processing. We'll explore: * The Mental Model Shift – From "query the database" to "continuously process the stream" using intuitive analogies * Flink SQL in Action: How familiar operations like SELECT, JOIN, and GROUP BY work on infinite data streams, plus temporal joins, time windows, and watermarks * Table API: Programmatic control with declarative simplicity, bridging SQL and complete programming flexibility * Flink AI: Real-time feature engineering and model inference on streaming data using SQL-like patterns * Real-World Patterns: Fraud detection during transactions, live analytics dashboards, and event-driven architectures You'll leave understanding not just how to use Flink SQL, but when and why it transforms traditional database skills into real-time data superpowers. Perfect for: SQL developers and data engineers ready to make their queries travel through time.

We are excited to announce our next Utrecht JUG meetup on **June 3rd** hosted by **Keylane**. Join us for an evening full of creativity, innovation, and practical insights from the Java and Spring ecosystem. As always, you can expect inspiring talks, great conversations, food, drinks, and plenty of opportunities to connect with fellow developers. We start the evening with food and drinks before diving into our first session, where **Alexander Chatzizacharias** takes Spring Boot far beyond its intended use case. In a talk that combines humor, curiosity, and technical depth, Alexander explores what happens when you use Spring Boot as the foundation for real-time game development. From IoC containers to event listeners, this session offers a fresh and entertaining perspective on the Spring ecosystem and the joy of learning by experimentation. After the break, **Josh Long** and **James Ward** take the stage with Bootiful Spring AI. Artificial Intelligence is rapidly becoming part of modern software development, and this session explores how Spring AI makes integrating AI capabilities into Java applications approachable and powerful. Expect an engaging introduction to modern AI concepts and a practical look at how the Spring ecosystem embraces the next wave of AI engineering. Please join us and RSVP! Because of the limited number of seats, please keep your RSVP up-to-date, so we can welcome someone else if you can't make it. **Timeschedule** 17:00 Doors open 18:00 Food & Drinks 18:45 Let's use Spring Boot to build games, because why not? by Alexander Chatzizacharias 19:45 Break 20:00 Bootiful Spring AI by Josh Long & James Ward 21:00 Drinks **Giveaway** 1 JetBrains licence **Talks** **Let's use Spring Boot to build games, because why not?** If you work on enterprise grade microservices on the JVM, you have undoubtedly heard of Spring Boot. Most developers see it as the reliable backbone of enterprise software. It is stable, predictable, and safe. But what if we took all those conventions and threw them out the window? What if we repurposed the IoC container, event listeners, and bean lifecycles to reveal what Spring Boot was always meant to be? A game development framework! Join Alexander as he attempts to deconstruct and demystify the Spring ecosystem by forcing it to do things it was definitely not designed for. We are not talking about simple text adventures here. We are talking about building complex, real-time games like a Terraria clone or a souls-like RPG, all powered by the same annotations you use for your day job. This session explores what happens when you learn technologies by breaking them. Whether you are a Spring veteran or a newcomer, this talk offers a fresh perspective on the tools you use every day. You will leave with a better understanding of how Spring Boot works under the hood and the inspiration to build something completely unnecessary, just because you can. Come for the absurdity, stay for the laughs, and see what happens when you strip away conventions and best practices in the pursuit of a wild idea. **Bootiful Spring AI** The age of artificial intelligence (because the search for regular intelligence hasn't gone well..) is nearly at hand, and it's everywhere! But is it in your application? It should be. AI is about integration, and here the Java and Spring communities come second to nobody. In this talk, we'll demystify the concepts of modern day Artificial Intelligence and look at its integration with the white hot new Spring AI project, a framework that builds on the richness of Spring Boot to extend them to the wide world of AI engineering. **Speakers** **Alexander Chatzizacharias** Alexander, a 35-year-old Software Engineer at JDriven, holds dual Dutch and Greek nationality. He earned his master’s degree in Game Studies from the University of Amsterdam, where he discovered his passion for gamification and software engineering. Alexander aims to bridge the gap between game development and software engineering, believing that both industries have much to learn from each other. He is dedicated to integrating technologies and methodologies from both fields. Additionally, he enjoys experimenting with new technologies and cutting-edge SDKs. **Josh Long** Josh (@starbuxman) has been the first Spring Developer Advocate since 2010. Josh is a Java Champion, author of seven books (including Reactive Spring), creator of numerous video trainings, open-source contributor, YouTuber, and podcaster. He is a well-known voice in the Spring community and a passionate advocate for Java developers around the world. **James Ward** Professional software developer since 1997, with much of that time spent helping developers build software that doesn't suck. A typed pure functional programming zealot who often compromises on his ideals to just get stuff done. Currently a Developer Advocate for AWS.

**This might be the girls night you didn’t know you needed.** Many women are living in constant “on” mode- always busy, always giving. And somewhere along the way, we forget how good it feels to simply *be together*. This is your invitation to a real **girls night, where you can come as you are.** Every 3 weeks we come together to relax, laugh, connect and support each other — without pressure, without fixing, without performance. **When women gather in a safe and supportive space, something powerful happens.** We uplift each other through shared laughter, honest conversations, and non-judgement presence. Being around other women who get it can make everything feel a little lighter and brighter. It helps us feel less alone, more supported, emotionally stronger - sometimes simply by being in the same room together. Sometimes we talk. Sometimes we listen, Sometimes we laugh - and even sing - until our bellies hurt. You’re free to share what’s on your mind, or simply enjoy the energy of being around other women who get it. There’s no agenda. No judgement. Just genuine connection, joy, and friendships that feel *easy and real.* And often, there’s that quiet thought: *“oh wow, I didn’t know I needed this.”* All I ask is that you come exactly as you are — tired, joyful, quiet, loud, curious, or unsure. Everything is welcome. We meet every 3 weeks - in Utrecht, Amsterdam or Leiden - because connection grows when we keep showing up for each other — not perfectly, just honestly. ✨ Come as you are. ✨ Leave feeling lighter, more connected, and a little more yourself.

'HOMEGOING' by Yaa Gyasi 'Two sisters with two very different destinies. One sold into slavery; one a slave trader's wife. The consequences of their fate reverberate through the generations that follow. Taking us from the Gold Coast of Africa to the cotton-picking plantations of Mississippi; from the missionary schools of Ghana to the dive bars of Harlem, spanning three continents and seven generations, Yaa Gyasi has written a miraculous novel - the intimate, gripping story of a brilliantly vivid cast of characters and through their lives the very story of America itself. Epic in its canvas and intimate in its portraits, Homegoing is a searing and profound debut from a masterly new writer.' ***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.*** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **PLEASE NOTE:** This is an IN-PERSON event in Amersfoort, The Netherlands.

\# This meetup is around a third\-party organizer\, Focus Filmtheater\. You can either purchase your ticket online or right before the session\. **Seats are numbered**. # **Title**: Treat Her Like a Lady **Language**: Dutch **Subtitles**: English **Length**: 110 min **Director**: Paloma Aguilera Valdebenito **More info**: https://www.focusarnhem.nl/agenda/english-subs-treat-her-like-a-lady/ **Ticket link**: https://www.focusarnhem.nl/tickets/144301/ **Synopsis:** When single mother Sandra (radiant performance from Nienke Plas) is evicted from her apartment due to fraud, she convinces her daughters that their emergency shelter is a holiday hotel. Sandra is just about keeping it together. Living with her two daughters and partner in a modest but colourful Amsterdam apartment, she makes ends (mostly) meet through cleaning jobs and welfare payments. But when she’s faced with a rapidly mounting series of hurdles – unpaid bills, an accusation of fraud, the revelation that her partner has been cheating – Sandra must draw upon all her determination and creativity to keep her daughters out of social care. An effervescent second feature from Dutch filmmaker and writer Paloma Aguilera Valdebenito (Out of Love, IFFR 2016), this jewel of a film offers poignant criticism of a broken social system with all the vibrancy and optimism of a musical. Nienke Plas is masterful in her central performance as the matriarch, whose fortitude, boldness and charisma bring to mind the best of Almodóvar’s heroines. Featuring a gorgeously saturated colour palette and a fabulous needle-drop soundtrack, Treat Her Like a Lady demonstrates how warmth and resilience can transform the most desperate situations into fresh opportunities for laughter and light. **How it works**: I will be at Focus around 18:30, where we can meet before the movie starts. You can message me to find us. Screening starts at 19:00. After the movie, we can have a drink together. Hope to see you soon!
