**DDD Aggregates & Your ORM** **By Matthias Noback** Over time you've created lots of data models that are mapped to tables in your relational database. Now you want to untangle the "mess" using Domain-Driven Design practices and patterns. This is very exciting; you're planning to separate your business domain into smaller subdomains, implemented by so-called Bounded Contexts, with explicit boundaries. But you are using an ORM, and the ORM knows about Entities, but it doesn't care about Bounded Contexts. It allows you (and often requires you) to link remote concepts in the code, ruining those boundaries you imagined... In this presentation, we'll explore the real-world problems you'll run into when trying to apply Domain-Driven Design patterns in an average framework/ORM-oriented code base. We cover central DDD concepts, and indicate potential conflicts with the way frameworks and ORMs treat your data model. Of course, we'll also consider work-arounds and solutions. **PROGRAM** 18:00 - Doors open, pizza and drinks **19:00 - Talk & discussion** 20:00 - Drinks & networking **ABOUT** 🤝 This meetup is **free**. 🍕 Food and drinks are provided at **no cost**. 🇬🇧 The presentation is in **English**. 📸 We might take pictures at the event, to upload to the meetup page and the Full Stack socials. 📍[Europalaan 40, 3526 KS Utrecht, Avenue Building - 3rd floor (PAQT Office)](https://maps.app.goo.gl/EJdxchKTEoLuc5UeA) **ABOUT THE HOST** PAQT.com devises, builds, and maintains software from a business perspective.

**⚠️ Notitie 1:** aanmelden loopt ***niet*** *via Meetup* maar moet op [https://con.infi.nl](https://con.infi.nl/) \- vandaar dat het even "vol" zal lijken op Meetup \(er is maar 1 "plek" hier\, voor de organizers\) **💡 Note 1**: this event is largely in *Dutch*. Na een paar jaar wachten is het weer zover! We hosten op **DONDERDAG 11 JUNI** **vanaf 13:00 (inloop vanaf 12:30)** weer een editie van Infi-Con: onze eigen kleine conferentie, compleet met internationale keynote spreker. **Aanmelden en info: [https://con.infi.nl](https://con.infi.nl)** (niet via Meetup dus) Wat je kunt verwachten: * 4 sprekers over "**Absurde en briljante tech**" (denk aan Roomba's met LIDAR, visualisaties met shaders, en meer!) * 1 keynote spreker (Engels), namelijk **Dylan Beattie**, over de **Rockstar** programmeertaal (er schijnt daadwerkelijke rock bij te komen kijken!) * **nerds** en tech-liefhebbers om mee te socializen (of tussendoor gewoon lekker chillen natuurlijk!) * een **borrel** met lekker stevige hapjes achteraf Zien we jullie op de 11e bij Infi? \-\-\-\- PS. The event is largely in Dutch, with a keynote and perhaps 1 or 2 talks in English. If you can follow spoken Dutch you're good to go (attendees probably happy to chat in English during breaks), but if you don't then it's possibly best to stay tuned for our upcoming Meetups which are quite often English-first.

**For this retreat you need to register via our website: https://www.maitreya.nl/nl/programma/another-world-is-possible** **Another world is possible with Ven. Amy miller** **Green Tara Practice as a Path of Compassion in Action** Our external world today often appears littered with division, violence, and alienation. Rather than grow dismayed by external experiences that show cruelty and heartlessness, let us explore how our vulnerability can become a source of resilience and positive change. This long weekend retreat offers a meaningful pause, a chance to reconnect with inner strength, inner wisdom and compassion. The beautiful Green Tara practice explores a path of inner transformation by being present with our pain, fear, and aversion. This retreat incorporates Lam Rim (Stages of the Path) meditation along with the sadhana and mantra recitation of Green Tara. By opening our hearts in kindness to ourselves and others, the potential exists for our external reality to shift more beneficially as well. Join us for this nourishing long weekend of practice, reflection, and renewal—and become part of a shared path of compassion that brings benefit both within and beyond ourselves. Venerable Amy Miller is a beloved spiritual teacher, practitioner and Buddhist nun in the Tibetan tradition. She has dedicated her life to sharing the profound teachings of Buddhism with the world. With her gentle presence, insightful wisdom and compassionate heart, she has touched the lives of many around the world, inspiring them to find inner peace and help transform their minds.

Maak je klaar voor je favoriete avond over het grootste onderwerp dat er is. Student? Registreer gratis! **De Nacht van de Ruimte 2026: Over moonshots en het belang van groot dromen.** Tickets+Info via: [www.nachtvanderuimte.nl](www.nachtvanderuimte.nl) Wat vandaag onmogelijk lijkt, is morgen misschien realiteit. Van missies naar de maan tot radicale oplossingen voor klimaatverandering: moonshots beginnen altijd met een idee dat groter is dan wat nu kan. Ideeën die schuren. Die onzeker zijn. Die misschien zelfs onhaalbaar lijken. Maar juist daar gebeurt het. Niet omdat we zeker weten dat het lukt, maar omdat het ons dwingt om anders te kijken, anders te handelen en grenzen te verleggen. Moonshots zijn geen eindpunt — ze zijn een motor. Voor verbeelding. Voor innovatie. Voor vooruitgang. Dus. Wat is jouw moonshot? Locatie: **Openluchttheater de Goffert, Nijmegen** Inloop: 19.45u. Start voorprogramma (live band): 20:00u. Start programma: 20:30u. Einde programma: ±22.15u. Borrel tot 23.00u.

**Agenda:** 17.00 - 18.00 Walk-in + Dinner 18.00 -19.00 **Fabric automated documentation** 19.00 -19.30 Short break 19.30 - 20.30 **How to get the most out of Fabric Data Factory** 20.30 - 21.00 Round-up and drinks **Sessions & Speakers** **Fabric automated documentation:** by Marco Hansma, Data Architect & Head of Data Engineering and Michael Wanzik, AI & Data Engineer **Session abstract** Documentation matters, but in practice it's often the first thing that gets neglected. It takes time, becomes outdated quickly, and feels like an administrative burden for many teams. In this session, we show how to approach this differently using Microsoft Fabric and AI not by adding yet another process, but by letting documentation emerge automatically as part of your normal data work. Through a live demo, we show how documentation is generated automatically, stays current, and is immediately useful for data engineers, BI specialists, architects, and business stakeholders. Think technical documentation, functional explanations, lineage context, and descriptions that helps people understand and use data faster and more effectively. We also cover how to handle this across different environments: from open innovation settings to organizations with strict security and compliance requirements. After this session, you'll leave with a clear picture of how AI can transform documentation from a forgotten afterthought into a natural part of your data platform. **Who is this for?** Data engineers, BI specialists, data architects, analytics engineers, platform teams, and anyone working with Microsoft Fabric or responsible for improving data governance. **What you'll take away** * How AI can automatically generate documentation within your data platform * How Microsoft Fabric can serve as the foundation for this * A practical example you can immediately apply to your own organization * How to get started, even in strictly secured environments **Session 2:** **How to get the most out of Fabric Data Factory** by Jeroen Luitwieler, Senior Product Manager, Microsoft As always, we're looking for speakers. So, if you have an interesting story to share, please submit your session to our [Call for Speakers](https://sessionize.com/dutch-fabric-user-group-2026/) If you're a first-time speaker, don't worry! We are more than happy to help you taking your first steps in the wonderful world of public speaking. Also, for all sessions submitted and not selected, we will keep a list of all sessions for future events.

We’re heading out for a beautiful 20 km loop hike from Afferden through the gorgeous Nationaal Park De Maasduinen. This route takes us through a striking Limburg landscape of forest, sandy paths, open heathland, river dunes, and wide views. Along the way, we pass the ruins of Kasteel Bleijenbeek and climb an uitkijktoren for a panoramic view over the Maasduinen landscape. One of the special features of this hike is that we cross the Maas river twice by small ferry. These crossings give the route an extra sense of adventure and connect the Maasduinen landscape with the village side of the river. After one of the crossings, we continue to the village of Vierlingsbeek, where we’ll take our longer break for a drink. After the break, we make our way back toward Afferden, completing a varied loop through forest, heathland, castle history, river scenery, ferry crossings, and quiet Limburg countryside. A hike with forest energy, open heathland, castle ruins, a lookout tower, two Maas river crossings, and a relaxed village drink stop. **📍When and where to meet?** We’ll meet at 11h15 at Busstop "Afferden, Veer naar Sambeek" https://maps.app.goo.gl/kcg4hBvRsHoUjBSa6 ⏰ **We start walking a few minutes after meeting up** We don’t wait for latecomers, as we have a long route ahead and want to enjoy the full day properly. **🚗 Coming by car?** Please check your parking options beforehand so you arrive on time. **⏸️ Planned Breaks** After **4 km:** break at watchtower (5 min) After **7 km:** Having a lunchbreak at ruins of Castle Bleijenbeek (25 min) After **13 km:** Ferry over the Maas After **14 km:** Drinks at bar in Vierlingsbeek (50 min) After **20 km:** Ferry back over the Maas (bring small change to pay the ferry) I still need to confirm or make a reservation at the bar. **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list.

**🦋 Local Book Club: The Seven Husbands of Evelyn Hugo by Taylor Jenkins Reid — Open to All** This month we're getting together to share reactions to The Seven Husbands of Evelyn Hugo, our selection by Taylor Jenkins Reid in a no-pressure setting where every view is welcome, and you rarely leave without a new perspective. Even a partial read is more than enough to contribute, and bring the lines that you think the group will find interesting, and bring your reading notes — because unfiltered reactions tend to open up the most interesting threads. The group is open to anyone interested — and you will find the group easy to talk with from the start, everything else is taken care of once you are in the room, and the relaxed setting means there is no pressure on you. Everything is open for debate — with all opinions treated as equally valid, and every reading of the same book turns out to be a different book. --- **Good to bring:** - A drink if you are bringing one — the evening can run long - Your copy of the book (physical or digital) - Anything you underlined or wanted to come back to - Your genuine reactions however complicated 💡 **Quick tip:** write down the one thing you would ask the author if you could, so you have something concrete to anchor your contribution, and the session repays whatever small preparation you put in. --- 🪴 A great discussion changes how you see a great book — grab a spot and bring the book and the rest is just a good evening with good people. See you at the session. 🪴

**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 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
