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.

**——————————**
**Event Description:**
**——————————**
Welcome product enthusiasts!
We're a meet-up group that hosts regular speaking events for those interested in the world of **digital products** and **doing things differently!**
Each meet-up features new guests from some of the most influential product companies around the world, providing unique insights, tangible ideas, and new techniques to help drive change from the inside out.
**————————**
**Event Format:**
**————————**
This is a **hybrid** event, offering the option to come along in person or join us from anywhere in the world online!
**————**
**Venue:**
**————**
🚨 We are at Wrap co-working Brighton, a stone's throw from the station. We're looking forward to seeing you there! 🚨
**————————**
**Our Supporters:**
**————————**
Our March event is supported by **[MPB](https://www.mpb.com/en-uk)** the world’s leading platform for buying, selling and trading used photography and videography equipment, making kit more accessible and sustainable for creators everywhere.

**————————**
**Our speakers:**
**————————**
**Steve Down**
**Steve Down is a Senior Product Manager at Channel 4, specialising in building high performing streaming apps for the biggest screen in the home.**
He’s spent years shaping TV experiences at major UK broadcasters, tackling platform fragmentation, performance constraints and all the quirks that make doing product on TV Apps a whole world of its own.
He regularly writes and speaks about the realities of Connected TV product development, sharing lessons from building and scaling TV apps across diverse platforms and fast changing user behaviours. His industry contributions unpack everything from platform limitations and UX challenges to experimentation gaps and the future of big screen viewing.
**————————**
**About the Talk:**
**————————**
**Behind the Streams: The untold story of TV App Product Management**
Forget what you know about doing Product Management on web and mobile - TV is a whole different ball game. You’re juggling dozens of platforms & stakeholders, designing for a lean-back user experience, and working in an environment where optimal performance is everything. Add in the giants like Netflix, Disney+, and YouTube as competitors, and standing out gets tough.
**In this session, Steve will pull back the curtain on:**
\- What makes TV product management so different
\- The skills you need to succeed in streaming
\- How you can break into one of the most exciting areas in product today
If you’ve ever thought about working in streaming or just want to know what happens behind the biggest screen in the house, this talk is for you.
**Raff Di Meo**
Senior Product Design Manager at Optimizely.
Raff has spent over 10 years designing products across startups, agencies, and enterprise SaaS, including a startup acquisition. Today, he's a Senior Product Design Manager at Optimizely, where he leads a team of designers reshaping how marketing teams create content across the web.
He's an active speaker in the UX community and writes Some Designers on Substack, championing inclusivity and supporting designers through a profession that won't sit still.
**————————**
**About the Talk:**
**————————**
**When too easy to use becomes a problem: from e-commerce returns to AI in design**
A few years ago, Raff designed a returns flow for an e-commerce product. It was fast, frictionless, and users loved it. It also helped normalise a behaviour that cost businesses millions and generated thousands of tonnes of waste. By every metric tracked, it was a success. By every metric not tracked, it was a disaster.
Today, the same pattern is playing out. Not just in the products we design, but in how we design them. Teams are reshaping their entire process around AI tools that can't even retain their own users. We're told the old ways are dead. Move faster. Ship more. Trust the tools.
In this talk, Raff will share what the returns project taught him about the gap between a successful design and a responsible one, and how those lessons are shaping how his team is navigating AI right now: what they're using, what's genuinely working, and what they're deliberately protecting.
You'll leave with three things you can take back to your team: why understanding the problem still comes first, how to explore with AI without losing your craft, and a dead-simple habit for catching unintended consequences before they ship.

Maximizing performance: Client state, garbage collection and grid intelligence.
Lets meet up at Conclusion Lowcode Company!
**Client State & Garbage Collection**
Curious how the Mendix Client really works under the hood? Join our meetup and uncover the secrets behind Client State & Garbage Collection and how they impact memory, performance and scalability of your applications.
* **How Client State works:** Understand how objects are stored in the browser, how state grows, and why it matters for app performance.
* **Garbage Collection in Mendix:** Discover how unused objects are cleaned up, what stays in memory, and what can cause unexpected memory bloat.
* **Performance pitfalls & best practices:** Learn how to avoid hidden state issues, optimize your microflows, and keep your app fast and efficient.
**Grid Inteligence**
We all know about grid congestion and challenges society faces as a result of it. Smart technologies such as demand-side management are key to combat grid congestion. The National Energy Dashboard (NED) which is an joint initiative from Gasunie en TenneT provides free data on energy consumption, production, transport and storage.
I present the Footprint Reductor as a lightweight plug-and-play Mendix module to bridge the gap between the data from the NED and Mendix applications.
• **Lightweight:** Find out how we kept flexibility while we were eliminating the need for technical know-how.
• **Performance:** Learn how we took the client state into account to enable optimal performance.
📅 **Program**
* 18:00 - 19:00: Walk-in + Drinks & Food
* 19:00 - 19:30: Client State & Garbage Collection
* 19:30 - 20:00: Grid Intelligence
* 20:00 - 20:30: Networking and Drinks

📅 **Datum:** Vrijdag 27 Maart 2026
🕐 **Tijd:** 12:30 – 17:00
📍 **Locatie:** Rubicon Cloud Advisor, Leusderend 36, 3832 RC, Leusden
**Wat kun je verwachten?**
**Agenda**
* 12:30 – Inloop met koffie en lunch

* 16:30 – Borrel & netwerken (tot 17:00 uur)
**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!
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 is wat jij het waard vindt
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**.

This meeting will help you learn about how to effectively overcome:
-Out-of-control unwanted emotions
-Low self-esteem
-Anxiety
-Negativity
-Stress
-Irrational fears
-Traumatic or painfully emotional incidents
-Breakups
-Betrayals
-Feeling like you're not really yourself
-Self-doubt...
We will discuss how to unleash the inner you and tap into your true potential. So come to this online meetup!
This meeting is sponsored by the Hubbard Dianetics Foundation of Central Ohio
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.
