Hi all! 🙂 On Wednesdays we welcome you to practice languages! If you want to practice a specific (uncommon) language, please send us a message so we can find some conversation partners for you on our mailing list! We hope to see you in Café Marktzicht! In the last year we had tables for the following languages: * Dutch * English * French * Italian * Spanish * Turkish\* * German\* * Portuguese\* * Danish\* * Norwegian\* * Russian\* * Arabic\* * Chinese\*\* * Japanese\*\* * Indonesian\*\* * * Most likely, but not every week present. \*\* - Rather rare ;-) If your language is not in this list, please let us know! We have a large database of Language Cafe visitors speaking 56 different languages! We might be able to connect you with a person that does speak the language you want to practice. In case you are not in our database yet, please use this form: http://goo.gl/forms/oSCn9Dn8m8

*(🇬🇧 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.

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.

Join in for a some drinks (and food, if you want) after work at **The 5th \| Utrecht**. Bring your own project and payment for drinks. As evenings tend to be a bit busier, we'll reserve a table. This means: **Only sign up if you are sure you will come!** And if there's no space left on the event, please don't join spontaneously. \-\-\-\-\- As always, we talk about our projects, exchange tipps, but also just get to know each other and enjoy a drink after a long day in good company. Whether it's knitting, crocheting, stitching, origami, or something more unique, we're looking forward to seeing you!

**DDSCC Meetup 7** 📅 **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 * 13:30 – Opening door DDSCC * 13:45 – Introductie door Rubicon Cloud Advisor * 14:00 – Jasper Oosterveld: With Great Power Comes Great Labeling: Sensitivity Labels in de Praktijk * 14:45 – Pauze * 15:15 – *Jeroen Bijdevier:* Je omgeving op orde voor veilig en optimaal Copilot gebruik * 16:00 – Ronde tafel gesprekken * 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.

🏔️ 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!

**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.

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

Central Ohio Radio Enthusiasts—CORE—is an informal community for anyone enthusiastic or curious about radio—whether you're new to radio and want to learn or you've been tinkering for years and want to share. Ham radio operators, GMRS users, Meshtastic fans, software-defined radio nerds, makers, and technical and non-technical folks are all welcome. No experience required or expected. This month we have **WiFi HaLow: Introduction and Practical Use** with **Alex Barbur**. Details are are [core.radio](https://core.radio).

While some are still meeting online, this is an in person event. Please note that we have attendees of all levels of speaking, including some native speakers. All are welcome! Also, as we meet at the same time and place each week, many don’t RSVP on the app, so we will likely have more attendees than noted here. Note: if you are asked to pay and upgrade the Meetup app, this is not necessary. You can ignore this and still attend our meetings.

**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.

**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. **YouTube Link** TBA

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
