Speltestavond #78
*(🇬🇧 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!
We gaan door tot een uur of 11, maar voel je vrij al eerder naar huis te gaan. Er is **gratis koffie** **en thee** bij StartUp Nijmegen. Voor fris, bier of wijn wordt een kleine bijdrage gevraagd. StartUp Nijmegen ligt tegenover het station. De auto kun je parkeren in de naastgelegen Keizer Karelparkeergarage (50 cent per uur). Er is hier ook een afgesloten fietsenstalling.
De testavonden in Nijmegen zijn elke **2e dinsdag** en elke **4e woensdag** van de maand. Zet die dus vast in je agenda (tip: zet met [deze iCal link](https://calendar.google.com/calendar/ical/c_d2267afce516f9296468270649b3f44da6c06cbc0bc3de05f049992373db5f4f%40group.calendar.google.com/public/basic.ics) ze automatisch in je agenda)!

🇬🇧 **For English-speaking guests:**
Before a board game or card game can be published, it must undergo extensive testing to ensure that it is enjoyable, clear, and always functions properly. Therefore, **every 2 weeks**, we gather with game authors from the region to test prototypes of games, thereby improving them and, perhaps, getting them published someday.
At 8 PM, we gather at [StartUp Nijmegen](https://startupnijmegen.nl/) for a game testing evening. Depending on the number of attendees and prototypes brought (feel free to bring something yourself), we form several groups. For smaller games, you can switch groups throughout the evening, but for larger games, you should discuss this.
**Even if you** **do not design games** or have a game you want to test, you are, of course, very welcome. It is very beneficial for designers to receive feedback from as many people as possible. And to be honest: testing new games is just a lot of fun!
We continue until about 11 PM, but feel free to go home earlier if you wish. There is **free coffee** **and tea** at StartUp Nijmegen. A small contribution is requested for soft drinks, beer, or wine. StartUp Nijmegen is located opposite the station. You can park your car in the adjacent Keizer Karel parking garage (50 cents per hour). There is also a secure bicycle parking facility here.
The testing evenings in Nijmegen are every **2nd Tuesday** and **4th Wednesday** of the month. So be sure to mark those in your calendar (tip: automatically add them to your calendar with [this iCal link](https://calendar.google.com/calendar/ical/c_d2267afce516f9296468270649b3f44da6c06cbc0bc3de05f049992373db5f4f@group.calendar.google.com/public/basic.ics))!

ArnhemJUG - March meetup
**ArnhemJUG**
We are excited to announce that we are welcomed by Avisi for the March meetup.
**Agenda**
* 17:00 CET walk-in
* 17:30 – 18:30 Food and drinks
* 18:30 – 19:30 talk: **Koog your own AI! Delicious recipes** by **Simon Vergauwen**
* 19:30 – 19:45 break
* 19:45 – 20:45 talk: **Domain-Driven Design** by **Dirk Groot**
* 20:45 – 21:30 drinks
**Koog your own AI! Delicious recipes**
Koog is an open-source Kotlin framework for building robust, and production-ready AI agents. Developed, and battle-tested in their own products by JetBrains!
In this session we’ll build an agent, and explore various techniques to tackle different kinds of problems, and complexity. How we can use model-context protocol (MCP) to give our agent access to external tools, and how to build custom tools to integrate with your own systems. How to define flexible graph workflows to design complex agent behaviors.
If you're not cooking your own AI Agents yet, you should! Join me and I’ll give you a taste of Koog.
**About** **Simon Vergauwen**
**Developer Advocate at JetBrains & OSS (arrow-kt) Maintainer**
**Software engineer from Antwerp, Belgium.**
Interested in everything functional, and Kotlin. Loves OSS, cooking, snowboarding and Fallou
**Domain-Driven Design**
What name should I give this entity? How should I deal with ambiguous terminology? Where should business rules be implemented? Is this validation part of the domain logic, or does it belong to the application layer? Which entities should be within the scope of this database transaction?
In this talk we explore how the **Domain-Driven Design (DDD)** methodology helps answer questions like these. We will cover the key DDD concepts, including **Ubiquitous Language**, **Bounded Context**, **Aggregates**, **Entities**, and **Value Objects**, and discuss how they fit within a software architecture.
The session is built around a practical example, so you will not only learn the theory behind DDD, but also see how these concepts can be applied in real-world software development.
**About Dirk Groot**
I'm a software engineer with more than 25 years of experience. Since my early teens, sofware engineering has been my greatest passion.

**Session description:**
**Jasper Oosterveld - With Great Power Comes Great Labeling: Sensitivity Labels in de Praktijk**
Veel organisaties hebben inmiddels sensitivity labels geïmplementeerd als basis voor data security in Microsoft 365. Maar zodra je voorbij de basis komt, ontstaan er nieuwe vragen.
Hoe ontwerp je een werkbaar labelmodel? Hoe voorkom je dat gebruikers verdwalen in te veel labels? Wat betekent labeling voor Teams, SharePoint, Data Lifecycle Management en Microsoft 365 Copilot? En waarom gedraagt het platform zich soms nét anders dan je verwacht?
Tijdens deze interactieve sessie deel ik mijn praktijkervaringen met sensitivity labels: keuzes die goed uitpakten, dingen die ik achteraf anders zou doen en de frustraties die je alleen tegenkomt wanneer je labels écht gaat gebruiken in productie.
Dit is nadrukkelijk geen theoretische sessie. Neem je eigen ervaringen, uitdagingen en meningen mee, zodat we samen praktijklessen kunnen uitwisselen en ontdekken hoe we sensitivity labels effectiever kunnen inzetten.
**Jeroen Bijdevier - Je omgeving op orde voor veilig en optimaal Copilot gebruik**
Copilot ziet het verschil tussen achterhaalde en recente informatie niet. Die zal je dus een beetje moeten helpen. Rechten zijn vaak niet (in detail) op orde. Manueel deze zaken vinden is lastig en tijdrovend. Natuurlijk wil je rapportages hebben van het gebruik. Ergo dataveiligheid op orde en inzicht in het gebruik met Purview.

🏔️ Summit Hike – Everest Edition (8,848 m)
🏔️ Everest Update for the Veluwe Power Hikers
We were preparing for a classic VPH high altitude expedition on top of the world. Unfortunately there is some disappointing news. Starting in 2026, Nepal is introducing strict new regulations for climbing Mount Everest. Climbers will now need to have previously summited a 7,000 meter peak in Nepal and must also submit mandatory health certificates.
Because we cannot realistically summit a 7,000 meter peak and then climb Everest on the same day during our hike, I am unfortunately obliged to change the program.
There is also another small complication. 1 April falls on a Wednesday, which makes organizing the expedition a bit difficult.
After a poll in the WhatsApp group, we decided to move the date to **28 March** and climb the highest point of the Veluwe, **Signaal Imbosch (110 m)**. Even if it’s not Everest, don’t underestimate this hike: we will cover **22 km with about 350 metres of elevation gain** at a brisk pace. At this altitude, however, oxygen bottles are no longer recommended.
Please update your RSVP if you can no longer attend due to the change. ⛰️🥾
**When and Where to Meet?**
10:10 sharp at Rheden Trainstation. ⏰ Please arrive on time, as we won’t be able to wait for latecomers. 🥾✨
https://maps.app.goo.gl/VaEtswyBps5awMoL7
**Where and When Shall We Rest?**
We’ll take 2 breaks:
* Lunch break in nature at Signaal Imbosch (110 m) with group photo on summit; 20 min
* Snack and drink at Basecamp (80 m) where you can buy drinks and snacks; 30 min
**Notifications:**
* Technical equipment: avalanche transceiver (beacon), avalanche probe, and avalanche shovel (if you have them)
* A compact lunch and water to share at the summit
* The hike will only be canceled in case of severe avalanche risk (code 5).
* If you plan to bring a companion, please ensure that they are also registered for the hike.
* To be the first to get updates on new hikes, join our WhatsApp group! Feel free to ask for the QR code during the hike to easily join.
* T-shirts are now available for €25, made from Fairwear-certified organic cotton with eco-friendly inks—sustainable, odor-resistant, and perfect for your hiking adventures (limited stock, available during the hike)! Let me know your size and I will bring one for you!
Walk & Talk in Arnhem Sonsbeekpark
Welcome to the event page of the Walk & Talk in Arnhem Sonsbeekpark, taking place on Sunday March 29th, 2026. This event is a informal walk where we will connect again and perhaps meet some new people. It will be the first day of Daylight Saving Time and, fortuitously, *Zeldzaam Mooi Markt* is taking place in Sonsbeek. We plan to make a stopover here. Our event is free and open for everyone to join, including Dutch and internationals.

buitenvaders op pad
Een wandeling voor vaders die het zichzelf gunnen om even te willen uitwaaien én de diepte in willen. We lopen samen door de natuur, ontmoeten elkaar en delen wat er echt speelt — als vader, als man, in je werk of gewoon in je hoofd.
Niets moet. Er is geen afleiding, alles draait om verbinden en inspireren. Onderweg doen we een aantal oefeningen, luisteren we naar elkaar en stellen we de vragen die er toe doen. Een ideaal moment om even tot jezelf te komen — die ontspanning neem je sowieso mee naar huis.
**Past dit bij jou?** Je hoeft geen antwoorden te hebben. Alleen de bereidheid om eerlijk te zijn — naar jezelf en naar de andere vaders om je heen.
**Wat kun je verwachten?**
* Een kleine groep van max. 8 vaders
* Een mooie route op de Veluwe
* Goede gesprekken en oefeningen onderweg
* Ruimte voor jouw verhaal
* Koffie/thee en een snack na afloop
Kortom: een wandeling waarmee je investeert in jezelf en je vaderschap.
duur: 10:00-12:00 uur / investering: €20
locatie: rondom Arnhem op de Veluwe
🏛️ Pastime #2 – The Romans in the Netherlands: Nijmegen (Noviomagus)
📍 Meeting point: **Nijmegen Lent Station** (⚠️ not Nijmegen Centraal!)
🗓 **Saturday, March 28th, 2026**
🕑 **14:00**
After starting our journey through Dutch history with **Prehistory**, it’s time to move forward to the **Roman era**.
And when we talk about Romans in the Netherlands, there is one unavoidable place to go: **Nijmegen**, the oldest city in the country, founded by the Romans as **Noviomagus**.
We’ll start from the other side of the river Waal and walk towards the historic city centre, combining **river landscapes, green parks and urban history**. Along the way we’ll explore how the Romans conquered large parts of what is now the Netherlands, built forts and military camps along the Rhine (the *limes*), and established their first real city here. This walk is about **stories, traces and layers of history**—and about seeing Nijmegen through Roman eyes.
🥾 **The walk is about 5 km** and will take us through nature, parks and the city while discovering the Roman past of Nijmegen and the Netherlands.
***
🍺 **Post-walk drinks at Cafe De Zon**
After the walk we’ll stop at **Cafe De Zon** to relax and have a drink together. It’s a perfect moment to chat, share impressions from the walk and wind down.
If you like beer, you’ll also have the chance to try **Oersoep**, a local craft brewery from Nijmegen known for its creative and experimental beers. Of course, other drinks are available as well.
***
A walk through **Roman history**, beautiful riverside views, and a relaxed drink afterwards — a perfect **Pastime afternoon**.

From Web Forms to Web Components - Burton Smith
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
**Abstract**
Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively.
This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way.

Contra dance with Big Scioty April 11 - Clinton Heights Lutheran church
**Caller: Kim Thompson**
**Band: Full Moon Country Dance Orchestra**
**Clinton Heights Lutheran Church**
**15 Clinton Heights Ave, Columbus, OH 43202**
WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing!
Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor.
Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner.
Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot.
For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/)
Please bring your own refillable water bottle.
How LLMs Like ChatGPT Actually Work and How to Build With Them
**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.
Free in-person event: Take Control of Your Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself.
Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went?
Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence?
Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

Take Control Of Your Life, Freedom From Negative Thoughts & Irrational Emotions
Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences.
Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future.
What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs.
At this free local Meetup event we will talk about:
* What causes grief, anxiety and depression to become chronic.
* Is it possible to regain your joy and happiness even after traumatic experiences?
* How to break away from negativity and focus on the future
* What are the steps to take to get control of your mind and your emotions?
Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home.
Let's explore safe, effective solutions for healing from traumatic experiences.
