Hi all! 🙂 It's BBQ time again! With a warm 36°C we figured we'd return to our regular spot in Wilhelminapark for the first language cafe BBQ of the season! We'll provide a BBQ or two, so please bring your own food to put on there, drinks, blankets, cutlery, maybe another BBQ, and anything else that you might need! See you there, in Wilhelminapark at 19:00! [https://maps.app.goo.gl/jheBHQ8QDvW4pYFk9](https://maps.app.goo.gl/jheBHQ8QDvW4pYFk9) In case you are not in our language cafe database yet, please use this form: [http://goo.gl/forms/oSCn9Dn8m8](http://goo.gl/forms/oSCn9Dn8m8) If you're joining us for the first time, just drop by to the Wilhelminapark this time and have fun! Note that our usual Wednesdays are in the Café Marktzicht. We will not organize any language groups in the park, but most people will speak English and Dutch.

*(🇬🇧 English below)* Voordat een bordspel of kaartspel kan worden uitgegeven, moet er veel aan het spel getest worden om zeker te zijn dat het leuk is, duidelijk is en altijd goed werkt. Daarom komen we **elke 2 weken** met spelauteurs uit de regio samen om prototypes van spellen te testen en ze zo beter te maken en misschien ooit wel gepubliceerd te krijgen. Om 8 uur verzamelen we bij [StartUp Nijmegen](https://startupnijmegen.nl/) voor een speltestavond. Afhankelijk van het aantal aanwezigen en prototypes dat er wordt meegenomen (neem zelf ook iets mee als je wilt) vormen we een aantal groepen. Bij kleinere spellen kun je in de loop van de avond van groep wisselen, bij grotere spellen moet je dat even overleggen. **Ook als je zelf** **geen spellen maakt** of een spel hebt dat je wilt testen, ben je natuurlijk van harte welkom. Het is voor ontwerpers heel fijn om de mening van zo veel mogelijk andere mensen te krijgen. En heel eerlijk: het testen van nieuwe spellen is ook gewoon heel leuk!

Join our first meetup on 24 June 2026. **Program:** 17:00 – 18:00 Walk-in + Dinner 18:00 – 18:45 Zero Trust: Applying Military Procedures to Cybersecurity Challenges - by Laurens Blankers (JDriven) 18:45 – 18:55 Break 18:55 – 19:40 Let's use Spring Boot to build games, because why not? - by Alexander Chatzizacharias (JDriven) 19:40 – 20:00 Practical AI Developer Setup Demo (by Alexander Chatzizacharias) — Learn how to integrate AI tools into your daily development workflow + Giveaway: **Win a 1-month Claude Code MAX subscription (worth €100)** 20:00 – 21:00 Networking Drinks About the talks: **Let's use Spring Boot to build games, because why not?** **Alexander Chatzizacharias - JDriven** 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. **Zero Trust: Applying Military Procedures to Cybersecurity Challenges** **Laurens Blankers - JDriven** Cybersecurity is becoming more and more challenging. A lot of ‘new’ solutions are being proposed, including Zero Trust. Although, if you really drill down to the core, Zero Trust proposes a way of working which has been standard in military organisations around the world for over 80 years. Join me in breaking down Zero Trust into a number of easily understood principles including a number of approaches which can be applied to your software today. Laurens is a Java Software Engineer with over 20 years of experience. He excels at extracting the bigger picture and applying this to the smallest details. He combines this theoretical knowledge with his vast practical experience and hands-on mentality. Laurens has significant experience with a number of Java based platforms, including Jakarta EE and Spring (Boot). Ranging from REST microservices in the cloud to applications for controlling custom hardware on the desktop. In his personal life Laurens enjoys Science Fiction, board games, and history of technology. **Practical AI Developer Setup Demo** **Alexander Chatzizacharias - JDriven** After the talks, Alexander will give a live demonstration of his AI-powered development setup and workflow. Discover how modern AI tools can help you write code faster, improve productivity, automate repetitive tasks, and accelerate learning. You'll get a practical look at the tools, techniques, and workflows that developers are using today to get the most out of AI. At the end of the demo, we'll hold a giveaway where one attendee will **win a** **1-month Claude Code MAX subscription (worth €100)**.

This meetup session will focus on ACL and SIGIR 2026 and feature three speakers from University of Amsterdam: **Yibin Lei, Zahra Abbasiantaeb** and **Dylan Jia-Huei Ju**. They will present their papers accepted at ACL and SIGIR 2026. **Location:** Science Park 904, Room C3.161 **Date**: Friday, June 26 **Time**: 16:00-17:00 **Zoom** **link**: [https://uva-live.zoom.us/j/65011610507](https://uva-live.zoom.us/j/65011610507) Details below: **Speaker #1:** Yibin Lei **Title:** Making Large Language Models Efficient Dense Retrievers **Abstract:** Recent work has shown that directly fine-tuning large language models (LLMs) for dense retrieval yields strong performance, but their substantial parameter counts make them computationally inefficient. While prior studies have revealed significant layer redundancy in LLMs for generative tasks, it remains unclear whether similar redundancy exists when these models are adapted for retrieval tasks, which require encoding entire sequences into fixed representations rather than generating tokens iteratively. To this end, we conduct a comprehensive analysis of layer redundancy in LLM-based dense retrievers. We find that, in contrast to generative settings, MLP layers are substantially more prunable, while attention layers remain critical for semantic aggregation. Building on this insight, we propose EffiR, a framework for developing efficient retrievers that performs large-scale MLP compression through a coarse-to-fine strategy (coarse-grained depth reduction followed by fine-grained width reduction), combined with retrieval-specific fine-tuning. Across diverse BEIR datasets and LLM backbones, EffiR achieves substantial reductions in model size and inference cost while preserving the performance of full-size models. **Bio:** Yibin Lei is a PhD student at the University of Amsterdam, where he works on information retrieval in multilingual and low-resource scenarios.He has co-authored multiple papers in leading conferences like ACL, EMNLP, and ICLR. Additionally, he has served as a committee member/reviewer for SIGIR, ACL ARR, NeurIPS and ICLR. **Speaker #2:** Zahra Abbasiantaeb **Title:** Conversational Gold: Evaluating Personalized Conversational Search System Using Gold Nuggets **Abstract:** As personalized conversational search systems increasingly rely on Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG), assessing the quality, relevance, and factual alignment of long-form responses remains a critical challenge. Traditional evaluation metrics often fall short when judging complex, multi-turn conversational outputs. In this presentation, we introduce **CONE-RAG**, a novel nugget-based evaluation paradigm designed to bridge the gap between retrieval effectiveness and generation quality. Moving beyond high-level surface metrics, **CONE-RAG** establishes a structured framework for long-form answer generation evaluation by centering on "gold nuggets"—concise, atomic units of essential information extracted directly from relevant source passages. We outline how the framework operationalizes automatic response evaluation through automated nugget extraction and semantic matching, explicitly linking generation quality back to retrieval performance. Attendees will gain insights into how this paradigm enables a deeper, more granular diagnostic assessment of RAG systems, establishing a rigorous new standard for evaluating personalized, context-aware conversational search. **Bio**: Zahra Abbasiantaeb is a Ph.D. student at the University of Amsterdam's Information Retrieval Lab (IRLab). Her research centers on improving conversational information seeking systems through advanced evaluation, query understanding, and personalized search framework design. Over the past three years, she has co-organized the TREC iKAT track, aiming to foster standard test collections and robust benchmarks for conversational systems. **Speaker #3:** Dylan Jia-Huei Ju **Title**: Search for Coverage: Learning Coverage-Aware Retrieval with Augmented Sub-Question Answerability **Abstract**: Long-form RAG introduces a new challenge of coverage-based ranking, where retrieval must ensure the inclusion of comprehensive and diverse relevant nuggets (i.e., facts) that can be synthesized into a thorough output. In this talk, I will present CoveR, a retrieval method optimized for coverage-aware retrieval. CoveR is trained with coverage contrastive and distillation objectives, designed to produce query representations that capture broader aspects of an information need. To support model training, we construct SCOPE, a dataset of 90K training pairs built with synthetic coverage signals derived from sub-question answerability judgments. Our experiments demonstrate that CoveR effectively balances relevance and coverage. We hope this study can facilitate further research on coverage-based ranking and more dynamic retrieval architectures for RAG. **Bio**: Dylan Jia-Huei Ju is a PhD student at the IRLab, University of Amsterdam, specializing in Information Retrieval and NLP with a focus on long-form Retrieval-Augmented Generation. His work targets the interaction between retrieval and generation, including retrieval evaluation and reranking for nugget coverage. **Counter:** SEA Talks #308, #309 and #310.

In this hands-on workshop we’ll work through four real-world scenarios in Python: finding the minimum viable context for sales questions, keeping frequency signals intact when summarizing support tickets at scale, selecting the right columns for churn analysis on a wide customer table, and extracting structured fields from messy product listings with validation you can trust. You’ll write and discuss code together — practical patterns you can take straight back to work. **Agenda** \- 18:00 Doors Open \- 18:30 Start of the Workshop \- 20:00 Workshop Closing & Announcements \- 20:10 Networking \- 21:00 Event Closing **GitHub Repo** [https://github.com/pyladiesams/feed-AI-agentic-beast-proper-data-jun2026](https://github.com/pyladiesams/feed-AI-agentic-beast-proper-data-jun2026) **Stream** [YouTube Stream](https://www.youtube.com/live/2EnszJLzzAc) **Speaker** [Jessica Eggen](https://www.linkedin.com/in/jessica-eggen-579b50155/) Jessica Eggen is a Data Analytics Engineer who loves to spent her time wrangling and puzzling with real-world data at scale.

**ArnhemJUG** We are excited to announce that we are welcomed by TenneT for the June meetup. Please note that TenneT **requires** all visitors to present a **valid ID** upon entry and that we must provide a list of attendees in advance. For this reason, **we need your full name** as it appears on your ID. If your Meetup username is different from your real name, we'll get in touch before the event to confirm the name on your ID. Also note that we start 10 minutes earlier than normal, the first talk will start at 18:20 **Agenda** * 17:00 CET walk-in * 17:30 – 18:20 Food and drinks * 18:20 – 19:10 talk: **How we develop and maintain our (12 year old) DDD app** by **Dan Haywood** * 19:10 – 19:30 break * 19:30 – 20:20 talk: **AI augmented teams: from tab complete to AI workforce** by **Radek Kowalski** * 20:20– 20:45 drinks **How we develop and maintain our (12 year old) DDD app** We’re a small team (about 2.5 FTEs) but we develop and maintain a big app - it processes €500m invoices in turnover each year, for a €4bn company that owns and operates shopping centres throughout Europe. And it’s a DDD app too … it’s our focus on the domain that allows us to do a lot with, well, not much. In this talk we’ll try to explain our way of doing things, some of which might be obvious and you’ll know, some of which could be a bit more contentious or surprising. The technology may intrigue you, but the mindset is just as important. **About Dan Haywood** Dan Haywood is an independent consultant based in the UK, an ASF member and committer to Apache Causeway. He spends his days either cutting code or advising governments. **AI augmented teams: from tab complete to AI workforce** Ten months ago, when Radek and his team launched their project under a tight deadline and limited budget, it seemed nearly impossible. Fortunately, it was 2025—and agentic coding tools were ready to help. The team embraced these tools as a lifeline, developing a workflow where engineers and AI agents built software side by side. The result: delivery ahead of schedule and within budget. In this talk, Radek shares how the team’s approach evolved, the practical strategies they developed, and the lessons they learned to overcome constraints in time and cost. **About Radek Kowalski** Over a 20+ year career in IT, Radek has grown from software engineer to architect to senior leader—before returning to the trenches to embrace the AI revolution and shape it firsthand. In the past year, he has helped organizations and engineering teams embed AI into both their business and daily workflows.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
