Human-Computer Interaction

De 37ᵉ monthly meetup van [Nimma.codes](https://www.nimma.codes/). Elke laatste dinsdag van de maand. Een cross-language user group voor software developers in de regio Arnhem-Nijmegen. **Locatie** 10KB. De Kolk 7, 6541 AV · Nijmegen Bekijk de routebeschrijving op: [https://share.cleanshot.com/FtP0Dkxw](https://share.cleanshot.com/FtP0Dkxw) Let op: het eten is er om 17:30. We starten om 18:00 met de opening. *We houden er niet van om eten te verspillen. Ben je verhinderd? Geen probleem, maar meld je uiterlijk een dag voor de meetup af.* **Programma** * 17:30 - 18:00 Inloop + food/drinks * 18:00 - 18:45 **Versleuteld data pseudonimiseren? - Job Doesburg** * 18:45 - 19:00 Pauze * 19:00 - 19:45 **Je AI-agent heeft root, en nu? - Roland Boon** * 20:00 - 21:00 Netwerken en gezelligheid **Versleuteld data pseudonimiseren? - Job Doesburg** Om privacy-vriendelijk gegevens uit te wisselen tussen systemen of organisaties, kan het waardevol of zelfs noodzakelijk zijn om te pseudonimiseren. PEP (polymorfe encryptie en pseudonimisatie) is een cryptografische methode om dit te doen, waarbij geen enkele partij in staat is om gegevens terug te linken. Hiermee kunnen verrassend sterke privacyeigenschappen worden bereikt en data zelfs effectief anoniem worden gemaakt. Naast de fundamentele technologie, laten we ook zien hoe dit toegankelijk is geïmplementeerd in de open-source libpep library (Rust, met bindings voor WASM/TS/JS en Python). Fun fact: deze technologie zit stiekem al ingebouwd in je rijbewijs. **Over Job Doesburg** Job Doesburg is promovendus aan de Radboud Universiteit. Hij doet onderzoek naar privacy en security en is werkzaam voor de afdeling software science en het Nationaal Onderwijslab AI, waar hij zich bezig houdt met “Duurzame Data”. Naast onderzoeker ziet Job zichzelf ook als software developer, zowel professioneel als hobbymatig. Hij vindt het belangrijk dat de inzichten uit de wetenschap ook écht in de praktijk gebruikt kunnen worden. **Je AI-agent heeft root, en nu? - Roland Boon** AI-coding-assistants zoals Cursor en Claude draaien met jouw rechten. Ze lezen en schrijven bestanden, voeren terminal commando's uit en doen netwerkverzoeken. Dat terwijl ze input verwerken waar jij geen controle over hebt: documentatie, tickets, dependencies, websites. Prompt injection is het SQL injection van het AI-tijdperk, alleen breder en subtieler. In deze talk gaan we (proberen) met live demo's te laten zien hoe onzichtbare instructies in ogenschijnlijk veilige tekst je AI-agent kunnen overnemen, en wat die agent vervolgens kan doen. Daarna bespreken we praktische defensiestrategieen en hebben we het graag over attack vectors en maatregelen die wij nog niet hebben bedacht. **Over** **Roland Boon** Roland Boon is eigenaar en software engineer bij 10KB. Met 20+ jaar ervaring in web development bouwt hij mission-critical bedrijfssoftware met een focus op security en privacy by design. Bij 10KB wordt intensief met AI-assisted development gewerkt, en met Manjikaze ([https://github.com/10KB/manjikaze](https://github.com/10KB/manjikaze "https://github.com/10KB/manjikaze")) werken ze aan het hardenen van hun eigen ontwikkelomgeving. Deze talk is ontstaan uit interne discussies binnen het team over hoe ver je een AI-agent kunt en mag vertrouwen.

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. Over her career, Holly has been a full-stack JavaScript developer, a build architect, a client-facing consultant, a JVM performance engineer, and an innovation leader.

**Welcome to our March UX Beers in Antwerp!** This time, we will host our event on Tuesday the 31st of March with [Dashdot](https://dashdot.be) at Plein Magazijn in Antwerp.

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.

**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:** How Not to Manage Your Microsoft 365 Tenant: And What to Do Instead - Dave Stork Managing a Microsoft 365 tenant can be deceptively simple (it is a commodity, right! Right?), but small misconfigurations can lead to security gaps and vulnerabilities. In this session, Microsoft MVP Dave Stork highlights common mistakes he encounters in real-world M365 environments and explains why they introduce unnecessary risk. More importantly, he demonstrates practical, secure alternatives based on Microsoft's latest guidance, CIS benchmarks, and field experience. Attendees will learn how to strengthen administrative identity, access, and posture with approaches such as least‑privilege administration, secure account design, Conditional Access, privileged access management, and automation-first operations. Expect pragmatic insights, recognizable examples, and actionable recommendations to immediately improve your tenant’s management.

Design Reimagined Utrecht - Forward Thinking & Designing for Sustainability: Shaping Mindsets, Creating Impact What does it take to design for a better, more sustainable future? Join us on Thursday, April 2nd in Utrecht for an inspiring evening where we explore how the way we think directly shapes the impact we create. In today’s fast-paced world, it’s easy to feel overwhelmed by constant change. We often fall back on what we already know, but that can limit creativity and growth. What if we could shift our mindset to see new possibilities instead? This session brings together mindset and sustainability, showing how forward thinking and intentional design can lead to meaningful, real-world impact. ✨ What to expect: How to develop a growth-focused, resilient mindset Practical tools to navigate change and stay in control Real-world insights on applying sustainability in design Ways to turn creative thinking into tangible impact Speakers: [Liva Grinberga](https://www.linkedin.com/preload/#) \- Educator for the Academy Awards Topic: Mastering the Art of Forward Thinking Explore how to embrace change, shift your perspective, and use simple tools to guide your thinking, unlocking creativity and new opportunities. [Sophie Morice](https://www.linkedin.com/preload/#) \- Design Excellence Lead\, Lysol \(Reckitt\) Topic: Designing for Sustainability: Passion to Impact Gain insights into how sustainability is applied in practice and how design can drive responsible, impactful outcomes. 📅 Date: Thursday, April 2, 2026 🕡 Time: 18:30 – 21:00 📍 Location: Hogeschool Utrecht, Padualaan 99 (Room 0.011) Whether you're a designer, student, or simply curious about sustainability and innovation, this is a space to learn, connect, and rethink what design can do. 👉 Come as you are, bring your curiosity, and let’s reimagine design together.

🌸 **Free online gathering** **Next circle: April 5** After this, we will continue meeting on the **first Sunday of each month**. A space to begin the month by returning to yourself. This women’s circle is an invitation to give yourself one hour to pause, slow down, and reconnect with your body, your inner voice, and other women. A simple and caring commitment: beginning the month with meditation and journaling in community. You can think of it as a small personal ritual, creating the habit of listening to yourself, writing, and setting intentions for the month ahead. We meet online on Sunday afternoons to gently transition into a new week and a new month, creating a moment of presence, reflection, and intention. During this 1-hour session we will explore: ✨ a guided meditation to arrive in the body ✨ a journaling practice to connect with what is alive in you ✨ a space for sharing, where you are welcome to speak or simply listen No previous experience is needed. You are welcome just as you are. Please have a notebook and a pen nearby, and join from a quiet space where you won’t be interrupted during the session. You are welcome to join once, or come back each month. The choice is yours. The first circles are offered for free in order to create community and open this space to more women. Participants who register for the event will receive the **Google Meet link** before the circle begins. It will be lovely to welcome you into this space 🌿

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

**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.

**Complex Trauma Support Group** Our group is intended for survivors of complex trauma. If you are here, it’s likely that so much of who you are and what you have experienced in this life is actually invisible to most people––to family, society, coworkers, and the people who are around you. We are a peer-led group of survivors creating opportunities for ourselves and others to share our experiences, share support, and build relationships in kind community together. Survivor experiences might include: child sexual abuse, incest, child trafficking, and other experiences of people living with traumatic dissociation and complex PTSD. **What to expect at your first meeting:** Currently, we are offering a bi-monthly in person group at 2:00pm on the first and third Sunday of the month. The only criterion for joining the group is that you are a survivor of trauma wishing to have more kindness in your own life and share kindness with others, and that you agree to practice to group’s relational agreements available for view here: https://www.kindgroups.com/agreements. Joining the group is free of charge. We ask that new people connect with us for 30 minutes on the phone or on zoom before coming to their first group, so that we can determine together that we are a good fit. Our meetings last approximately 90 minutes. Participants are never required to share. You’re also welcome to choose a pseudonym and you will never be asked for private information. You are welcome to leave at any time. The kindness that survivors can share when among others who have survived similar childhood experiences is something we rarely get to experience. Time spent with others who understand even a little bit more about us is a relief. Our hope is to help ourselves and others experience that we are not alone. We wish for our efforts to be a cause of kindness in our own lives and the lives of each other. You can read more about the groups at www.kindgroups.com.

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.
