**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.

Hallo liebe Java User Group Mitglieder! Diesmal haben wir Thomas Künneth mit seinem Talk zum Thema "**Climbing the Codeberg - Some Developer's Thoughts on Leaving GitHub**" zu Gast. Wir freuen uns euch zu sehen (virtuell oder vor Ort). * 17:45 Uhr: Einlass * 18:15 Uhr: Talk * ab 19:00: Ausklang des Abends Dank an [codecamp:n](https://www.codecamp-n.com/) für Location, Bier und Pizza! \-\-\- As developers increasingly prioritize privacy, digital sovereignty, and true open-source values, many are questioning their reliance on corporate-owned platforms like GitHub. Enter Codeberg—a community-driven, non-profit Git hosting platform funded by donations and powered by Forgejo. But is the grass really greener, and how difficult is the transition? In "Climbing the Codeberg," we’ll explore both the philosophical motivations and the practical realities of leaving GitHub. Walking through a firsthand developer's journey, this talk will guide you through the process of establishing your code’s new home and taking back control of your workflow. In this session, we will cover: * The "Why": Understanding the fundamental differences in philosophy and legal structure between a corporate-owned giant and a non-profit, community-led alternative like Codeberg. * Safe Migration Strategies: Step-by-step insights on migrating repositories (including metadata like issues and releases), proving your identity via Mastodon, and utilizing "tombstoning" techniques to avoid critical security risks like namespace hijacking on your old GitHub account. * Restoring Automation: Leaving GitHub doesn't mean leaving CI/CD behind. We'll dive into leveling up your new environment by setting up local Codeberg Actions runners, exploring both containerized (Docker) approaches and host-level (act_runner) configurations for architectures like Apple Silicon. Whether you are ready to make the full leap to a community-owned forge or simply want to explore what true digital sovereignty looks like, this session will equip you with the tools, commands, and insights needed to successfully summit the Codeberg. \-\-\- Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

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 **Speakers** 🎤 Tim Speksnijder Mendix developer with a millisecond mindset 🎤 Frank Dennissen Mendix developer with a sustainability spark **Directions & Parking** This time we host the meetup NOT in our Utrecht office, but in our Nieuwegein office.

Zaterdag 28 maart houden hackerspaces in Nederland een open huis, ook Randomdata is van de partij. Hackerspace zijn locaties waar mensen met een technische, creatieve en nieuwsgierige mindset bijeenkomen om te werken aan projecten, elkaar te ontmoeten en te praten over onderwerpen die hen interesseren. Tijdens de open dag is het mogelijk om zelf te ontdekken wat hacken inhoudt en te zien wat er allemaal mogelijk is in een hackerspace. Tipje van de sluier? Iemands verbeeldingskracht is de meest beperkende factor! Iedereen is welkom om een kijkje te komen nemen tijdens deze jaarlijks terugkerende open dag. De deuren zijn geopend vanaf 13:00 uur, en om 17:00 is het dagprogramma afgelopen. Enkele voorbeelden van activiteiten die je kan doen: * Leren hoe kwetsbaar systemen zijn en wat daar aan gedaan kan worden. * Kennis opdoen over de juiste bescherming van je privacy en persoonsgegevens. * Zelf 3D-modellen maken en 3D-printen. * Een introductie tot Linux (neem hiervoor je laptop mee). * Een introductie tot Arduino of Raspberry Pi.

*Since the guided meditations for this event are in Dutch, this description is too.* Wil je je drukke week afsluiten en ontspannen aan het weekend beginnen? Dan ben je geheel vrijblijvend welkom bij de vrijdagavond meditatie van [Jewel Heart](https://www.jewelheart.nl/). Deze meditatieavond heeft een licht en open karakter. De meditaties bestaan uit drie delen. We beginnen met het gewaarworden van je lichamelijke sensaties. In een korter deel twee doen we een loopmeditatie en in deel drie is er een eenvoudige, geleide visualisatie meditatie. Het geheel wordt afgesloten met een gesprek onder het genot van een kop thee, voor wie daar zin in heeft. 📍[Jewel Heart, Hatertseveldweg 284, Nijmegen](https://maps.app.goo.gl/D4FzqLbkaqs2JNDG8). Loop de oprit op en dan is de ingang aan je rechterzijde 🕒Zaal open vanaf 19.30 uur, meditatie van 20.00 tot 21.00 Je bent van harte welkom! Aan deze activiteit kun je per keer meedoen. Er zijn geen verplichtingen. Op vrijwillige basis kun je op de avond zelf een donatie doen.

**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!

Main Library, Meeting Room 2B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

**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
