**Details** The Workplace Ninja User Group Netherlands is proud to announce that on Wednesday the 1st of April 2026 we will organize our 2nd in-person event in the year 2026. **Program:** **15:30 - 16:00: Welcome at location** **16:00 - 17:00: Session 1: Jorik Polhuis “Copilot als reality check: wanneer AI je project niet spaart”** **17:05 - 18:05: Session 2: Arno van Dijk, "How to Protect Your Tokens with Intune & Conditional Access"** **18:05 - 19:00: Food, drinks and networking, sponsored by location host** **19:00 - 20:00: Session 3:** **20:00 - 21:00: Drinks and networking** Location: \ **Session 1: Jorik Polhuis “Copilot als reality check: wanneer AI je project niet spaart”** Wat gebeurt er als je Copilot vraagt om eerlijk te zijn over je project? In deze sessie bouwen we samen een agent die niet samenvat, maar **kritisch meedenkt**: wat klopt hier niet, wat missen we, en waar lopen we risico zonder het te benoemen? Aan de hand van een herkenbare projectcase laten we zien: * hoe je van een idee naar een agent komt * waarom agent‑denken iets anders is dan prompten * en waar het misgaat zonder goede afspraken en data **Session 2:** How to Protect Your Tokens with Intune & Conditional Access - Arno van Dijk When accessing resources with Single Sign On, the Microsoft Services makes use of a Primary Refresh Token (PRT). This token is created when a device is registered so it can make use of Single Sign On. Now a days token theft is becoming a huge problem. Luckily Microsoft has released several features to reduces the possibility for Token theft. Read on to learn more about the profile possibilities in Intune and how to enforce your token protection with Conditional Access **Session 3:**

We are excited to announce our next Utrecht JUG meetup on **March 31, 2026**. And this one is extra special as we celebrate the **10-year anniversary of the Utrecht Java User Group!** For a decade, the Utrecht JUG has been bringing together Java developers to share knowledge, exchange ideas, and build a strong local community. We’re proud of how far we’ve come and we’re celebrating in style with two world-class speakers: **Holly Cummins and Dr. Venkat Subramaniam.** In the first session, Holly Cummins will challenge us to rethink what really impacts our daily work as developers. From physics and the speed of light to statistics, economics, and the end of Moore’s Law, this wide-ranging and thought-provoking talk explores why topics we once ignored may now be critical to our success. We’ll dive into concurrency, Project Loom, AOT, and why certain ideas that were “bad” before might suddenly be the right choice today. After the break, Dr. Venkat Subramaniam will explore the power and perils of AI-assisted development. Tools like GitHub Copilot and ChatGPT can dramatically improve productivity, but only when used wisely. In this practical and insightful session, Venkat will demonstrate how to leverage AI effectively, understand its limitations, and make better engineering decisions when building applications. Join us for an evening full of big ideas, practical insights, great conversations and a celebration of 10 years of Utrecht JUG! 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 17:30 Food & Drinks 18:15 Things You Thought You Didn’t Need To Care About That Have a Big Impact On Your Job by Holly Cummins 19:15 Break 19:30 The Power and Perils of Using Copilot and ChatGPT for Application Development by Venkat Subramaniam 20:30 Drinks *** # Talks ## Things You Thought You Didn’t Need To Care About That Have a Big Impact On Your Job Development is about working with computers, right? Well, not quite. Development is about working with computers (easy), and working with people (hard). And it’s also about physics. Things like the speed of light and thermodynamics influence APIs because they influence hardware and networking. Statistics, whether we liked it at university or not, is shaping modern development workflows. Economics — including the end of zero-interest rates — is influencing hiring and the broader tech landscape. In this wide-ranging talk, Holly will explore why the end of Moore’s Law means we may finally need to embrace concurrent programming properly, why Loom is a good idea now when green threads once weren’t, why AOT has become attractive again, and how much business, finance, and statistics should matter to us as developers. *** ## The Power and Perils of Using Copilot and ChatGPT for Application Development Tools serve us well when we understand their power, know when to use them, and use them wisely. AI tools are no different. In this presentation, we’ll look at practical ways to use AI tools like Copilot and ChatGPT in application development. We’ll explore how they can improve productivity and creativity — and where caution is needed. You’ll learn how to benefit from AI while staying effective, responsible, and in control as a developer. *** # Speakers ## Holly Cummins Holly Cummins is a Senior Principal Software Engineer on the IBM Quarkus team and a Java Champion.

No roadmap. No procurement cycle. No feature request backlog. Just solve the problem. Thanks to vibe-coding, building software is becoming accessible to the people who actually experience the friction. Instead of waiting months for a feature or adapting your workflow to a generic tool, you create something that fits your problem, your process, and your team. Tools like Lovable make that possible. And this shift is bigger than it may seem. This isn’t really about a waffle charts generator or poster tiling tools. It’s about what happens when building software on demand becomes normal. When the people closest to the problem can create the solution, exactly when they need it. **Talk 2:** Digital inclusion in public transport Sjoera Roggeman Public transport is a fundamental service that should be available to everyone. But as services become increasingly digital, there is a real risk of excluding people who are less digitally confident, or have specific needs for using digital products. That’s why De Lijn implemented an “easy mode” within the existing app, a simplified interface that reduces complexity and makes key tasks more straightforward and intuitive. In this talk, Sjoera will walk you through the design process from start to end, and share her learnings and challenges as a UX designer on this project. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# SCHEDULE 18:00 - Doors open.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.
