Adventure Racing

The tour will be conducted in both English and Dutch! On the afternoon of March 31st, the Journal of Trial and Error, in collaboration with Utrecht Time Machine, organizes the Trial and Error City Tour. During this guided walk through the city centre of Utrecht, you will hear stories about what went wrong in the city’s past. The tour covers both historical episodes and more recent events, offering a different way to get to know Utrecht. The tour is led by guides with extensive knowledge of Utrecht’s history lasting from 16:00 to 18:30 including drinks. It is a one-time event with limited availability (only 25 spots). Are you curious about how Utrecht became the city it is today through trial and error, and would you enjoy sharing your own experiences along the way?

**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.

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.

This hike picks up the trail where we left it on March 8, in Culemborg. We then crossed the river Lek. We will now continue southwards to the river Linge, over mostly unpaved (and sometimes muddy) paths. With some luck, we will see apple, pear and cherry trees in full bloom, as they grow abundantly in this area. **Meeting time and place**: we will meet at **10.15am** at train station Culemborg. The hike ends at train station Beesd, where we will arrive around 3pm. **This hike is fully booked.** [You may sign up for a place on the waitlist on my website](https://rewildyourself.nu/dutch-nature-hikes/)**.**

Hi everyone! For those who want to enjoy a particularly unique adventure in (mostly) nature, you're welcome to join me in this special Easter hiking excursion! Pay attention, the route is 40km so it's not absolutely hike beginners. For first-timers (and as a helpful reminder 😉), I recommend that you wear a comfy outfit & shoes and bring (lots of) water & a snack or two. At some points during the excursion, we will do breaks to rest and eat/drink for a while. But expect a steady pace faster than the normal hikes but not powerhiking pace. I'd saythink on average 5km/h. It's a marathon not a race 😜 Lastly, after the hike we 100% go for food and drinks. More info about the route/location: It's simple. Put on Google maps starting point Utrecht centraal & end point Amsterdam centraal, and there's your route 😊 More tips on finding the group along with helpful contact info with the host will follow in the comments the day before the meetup. To those interested, hope to see you there! 😄 In case of bad (NL) weather, the event might be moved to another day or canceled

**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.
