I’m putting together a small hike trip weekend in Hoorneboegse heide in Hilversum, the idea is to come with a few people who want to step out of their routine, spend time in nature, and meet others in a relaxed way. This is not a tour or a structured retreat. The idea is simple step out of your comfort and everyday life to reconnect with nature and with each other. We will – explore the beautiful nature – share a few moments together – and keep things easy and natural There will be time together (walks and sunset). Group size will be small (around 2- 4 people), to keep it comfortable and personal. This Meetup is to connect people who are interested in real and human connection If this resonates, feel free to join and I’ll share more details 🙂

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

AI is inmiddels overal in softwareontwikkeling te vinden. Van code genereren tot documentatie schrijven, van workflows automatiseren tot agents die zelfstandig acties uitvoeren. Maar hoe houd je grip op tools die niet altijd hetzelfde antwoord geven? En wie is er uiteindelijk verantwoordelijk als AI daadwerkelijk iets gaat doen? Tijdens deze meetup duiken we in de praktische kant van AI in software engineering en test automation. Zoals altijd georganiseerd door deTesters, TestCoders en TechChamps, in ons kantoor in de Werkspoorkathedraal in Utrecht. Deze keer hebben we twee talks die mooi op elkaar aansluiten. Ghislain Gabriëlse laat zien hoe je AI skills kunt testen wanneer klassieke assertions niet meer genoeg zijn. Bert Jan Schrijver neemt ons mee in de bredere vraag wat AI agents betekenen voor software engineering, verantwoordelijkheid en controle. Twee talks, twee invalshoeken, maar allebei heel relevant voor iedereen die serieus bezig is met kwaliteit, test automation en de manier waarop AI ons vak verandert. **The Agent Who Tested Me: Behavioral Testing for AI Skills** Hoe test je tools die elke keer net een ander antwoord kunnen geven? Ghislain laat zien hoe zij AI skills testen met echte Copilot sessies, zonder alles weg te mocken. Want bij LLMs kun je niet simpelweg een assertEquals op de output zetten. Tenzij je van mega flaky tests houdt. In deze talk neemt hij je mee in een framework waarmee AI skills op verschillende niveaus worden gevalideerd. Van deterministische checks en een LLM Judge tot baseline vergelijkingen en variance analysis. Zo wordt niet alleen gekeken of een skill iets teruggeeft, maar ook of het antwoord klopt, waarde toevoegt en betrouwbaar genoeg is. Een praktische sessie over testen, CI en non determinisme voor iedereen die bezig is met AI, test automation of Copilot skills. **Ghislain Gabriëlse** Ghislain Gabriëlse is een ervaren Test Automation Engineer met ruim 11 jaar ervaring in testen en automatisering. Hij richt zich vooral op het ontwikkelen en inrichten van tools en frameworks die de developer experience verbeteren, zodat teams beter en efficiënter kunnen ontwikkelen en testen. **Software engineering in the age of AI agents: who’s in control?** Een AI verwijdert een production database en blijft vervolgens volhouden dat dit niet is gebeurd. Welkom in moderne software engineering. Generatieve AI wordt steeds vaker een echte samenwerkingspartner. Het schrijft code, past systemen aan en voert acties uit. Maar dat betekent niet automatisch dat het ook doet wat wij denken dat het doet. In deze presentatie neemt Bert Jan ons mee in wat er echt verandert. Niet alleen in hoe we code schrijven, maar vooral in hoe we controleren, begeleiden en verantwoordelijkheid nemen. De rol van engineers verschuift steeds meer van zelf bouwen naar richting geven, beoordelen en kritisch blijven kijken naar wat AI oplevert. Aan de hand van persoonlijke verhalen, inzichten uit de industrie, successen en mislukkingen laat Bert Jan zien hoe je verantwoord om kunt gaan met AI tools die zich razendsnel ontwikkelen. Want ook als je AI het werk laat doen, blijf jij verantwoordelijk voor de uitkomst. **Bert Jan Schrijver** Bert Jan Schrijver is CTO bij OpenValue en houdt zich bezig met Java, AI, software architectuur, Continuous Delivery en DevOps. Hij is Java Champion, JavaOne Rock Star speaker, winnaar van een Duke’s Choice Award en bestuurslid bij NLJUG, de Nederlandse Java User Group. Daarnaast deelt hij graag zijn kennis op conferenties, schrijft hij voor het Nederlandse Java Magazine en helpt hij bij Devoxx4Kids om kinderen te leren programmeren. **Doelgroep** Deze meetup is interessant voor testers, QA engineers, developers en iedereen die bezig is met kwaliteit in moderne software teams. Deze avond is **volledig in het Nederlands (Dutch spoken).** **Programma** 17:30 Ontvangst en eten 18:30 The Agent Who Tested Me: Behavioral Testing for AI Skills 19:30 Korte pauze 19:45 Software engineering in the age of AI agents: who’s in control? 20:45 Q&A en discussie 21:00 Afsluiting met een borrel

​**Europe 2031: A Scenario, and the News That's Catching Up to It** ​This session will discuss *Europe 2031: What getting AI wrong means for us*. A recent scenario-narrative imagines, through two fictional Europeans, how the continent could lose the ability to shape its own future by mishandling the AI transition. ​Just days after the document was published on 11 June 2026, Anthropic, in compliance with recent US national security directives asking to restrict access to its most advanced models to US citizens only, suspended services for Fable 5 and Mythos 5 for all users. ​We'll use the story as a starting point and discuss the policies the EU is applying and the concept of AI sovereignty, and the potential consequences of this new race. We are going to use Draghi's report's competitiveness diagnosis as the policy backdrop and the current stance of the EU regarding its AI sovereignty. ​Address: Utrecht Drift 27, Room 0.72 ​Documents: ​1) [https://europe2031.ai/](https://europe2031.ai/?utm_source=luma) 2) [https://commission.europa.eu/topics/competitiveness/draghi-report_en](https://commission.europa.eu/topics/competitiveness/draghi-report_en?utm_source=luma) 3) [https://digital-strategy.ec.europa.eu/en/policies/cloud-and-ai-development-act](https://digital-strategy.ec.europa.eu/en/policies/cloud-and-ai-development-act?utm_source=luma)

We are bringing Microsoft Build sessions to Columbus Ohio! The Central Ohio Azure Meetup and Central Ohio .NET Developer's Group (CONDG) are coming together to bring some of the labs and breakouts from Microsoft Build to your backyard. In this free, 1 day event, you are going to Build stuff with us! And yes, there will be free food. Please RSVP via [Microsoft Build //localhost:columbus | Microsoft Reactor](https://developer.microsoft.com/en-us/reactor/events/27247/).

On Thursday, June 18, 2026, we will meet in the 700N Conference Room at 700 N Hurstbourne Pkwy for a special Louisville .NET Meetup as we host **Microsoft Build //localhost:louisville**. Doors open at 6:00 p.m., and the presentation will begin promptly at 6:30 p.m. TEKsystems will provide food, so please RSVP to help us plan appropriately. The session will also be streamed at **[https://twitch.tv/TaleLearnCode](https://twitch.tv/TaleLearnCode)**. This month, we’ll dive into the most important announcements from **Microsoft Build 2026**. Chad Green will present a curated, developer‑focused walkthrough of the new capabilities across .NET, Azure, AI, developer tooling, and platform updates. We’ll explore what these announcements mean for architects and developers, how they fit into real‑world solutions, and which changes you can start applying immediately in your projects. And then, Rob Richardson will present: ### **GitOps: Easy Deploy and Even Easier Rollback** GitOps isn't just for containers. The methodology of deploying from a build is now baked into our culture. Take it a touch farther with infrastructure as code and a few extra techniques, and you can reliably deploy to any platform: cloud, on-prem, container, PaaS, and more. Join us as we learn the methodology of GitOps, the critical pieces you need in place, and the elegance of rollbacks with GitOps. You'll leave with a working repo of deployment techniques that doesn't consume any paid tools or container-specific techniques. **Important:** To participate fully, please RSVP in **both** places: * **Louisville .NET Meetup** (this page) * **Microsoft Build //localhost:louisville registration**: [https://developer.microsoft.com/en-us/reactor/events/27112/](https://developer.microsoft.com/en-us/reactor/events/27112/) After the session, we’ll head to Brick House Tavern to continue the conversation over food and drinks.

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

Welcome, readers! Our June read is ***Endurance: Shackleton's Incredible*** ***Voyage*** **by Alfred Lansing.** A work of nonfiction, and one of the most astonishing survival stories in history, we follow Sir Ernest Shackleton and his crew after their ship is crushed by Antarctic ice. Stranded in one of the harshest environments on Earth, the men endure months of isolation, freezing temperatures, and near starvation—yet refuse to give up hope. Lansing brings their ordeal to life through vivid detail and firsthand accounts, capturing both the brutality of nature and the resilience of the human spirit. At its core, the story is a powerful testament to leadership, perseverance, and the unbreakable will to survive against impossible odds. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **all** **drinks must be purchased at the bar.** Happy reading! 📖
