Half of the group \(mixed gender\) will stay in a fixed place and the other half of the group \(mixed gender\) will be asked to rotate\. During these intervals\, each pair of people will get the opportunity to talk to each other\. \- Lara will be hosting the evening and she will organize the fast friending process\. She will indicate when you should move to the next person\. \- From 8\.30 onwards we will stop the system and people will have to chance go chat and interact with those they have met as well as others\. If you are a bit shy or anxious then please come early. Lara will help you meet other members in a small group and help you settle down and get comfortable. All attendees are also welcome to bring a lady friend along with them for free. This will make it a lot less stressful for you as you will always have your friend alongside. \- We are not a close knit tight group\. Our evenings are warm and comfortable for members attending for the first time and those coming alone\. You will not feel alone\! \- We have many groups in this city\.

Taucht ein in die Welt von GitOps! Euch erwarten zwei spannende Vorträge rund um FluxCD in der Praxis. Christian Fritz teilt seine Erfahrungen aus zwei Jahren produktivem GitOps-Einsatz – von Erfolgen bis zu Stolpersteinen. Thorsten Wussow zeigt live, wie Progressive Deployments mit Flagger und Istio für sichere und hochverfügbare Kubernetes-Deployments sorgen. Perfekt für alle, die GitOps evaluieren oder ihre bestehenden Setups optimieren möchten! **Dieses Meetup wird ausnahmsweise auf Deutsch sein und HYBRID\. \|** Zoom Link wird ein paar Tage vor dem Event in Meetup zu Verfügung gestellt. **\*\*\* AGENDA \*\*\*** * 18:30–19:00 Uhr \| Einlass mit Snacks und Getränken\. * 19:00 Uhr \| Begrüßung und Einführung \- Start des hybriden Meetups 19:05 Uhr \| GitOps Adventures aus der Praxis: Lessons Learned \- Zwei Jahre GitOps mit FluxCD in Produktion von Christian Fritz \(QAware GmbH\) ca\. 20:05 Uhr \| Flux mit Flagger und Istio \- Progressive Kubernetes Deployments von Thorsten Wussow \(Slix GmbH\) Anschließend: Weitere Snacks und Getränke und viel Zeit zum Networking mit allen Teilnehmern und Referenten. **\*\*\* ABSTRACTS \*\*\*** **GitOps Adventures aus der Praxis: Lessons Learned - Zwei Jahre GitOps mit FluxCD in Produktion von Christian Fritz (QAware GmbH)** Diese Etappe des GitOps Adventures erzählt aus dem wahren Leben: Seit zwei Jahren arbeite ich in einem Projekt, das schon zu diesem Zeitpunkt auf GitOps mit FluxCD setzte. In diesem Vortrag zeige ich unser aktuelles GitOps Setup und wie neue Features über unsere drei Stages in die Produktion gelangen. Dabei zeige ich die Vorteile wie bessere Reproduzierbarkeit und Effizienz, gehe aber auch auf Herausforderungen und Nachteile ein: von komplexen Fehleranalysen bis hin zu organisatorischen Stolpersteinen. Außerdem gebe ich einen Ausblick, wo wir noch Verbesserungspotenzial sehen. Dieser ehrliche Erfahrungsbericht bietet praktische Einblicke und Learnings für alle, die GitOps evaluieren oder weiterentwickeln wollen. **Flux mit Flagger und Istio - Progressive Kubernetes Deployments von Thorsten Wussow (Slix GmbH)** Heutzutage ist eine hohe Erreichbarkeit von Applikationen essentiell, auch bei einem Wechsel auf eine neue Version. Ebenso gibt es eine hohe Kadenz der Bereitstellungen. Dies birgt immer das Risiko, das sich Fehler in der neuen Version einschleichen, oder Ausfälle der Software während der Bereitstellung auftreten. Eine Möglichkeit das Risiko zu minimieren ist das Verwenden von verschiedenen Deploymentstrategien wie z.B. Blue/Green Deployments, Canary-Deployments oder A/B-Testing. Ein Tool das uns hier sehr gut unterstützen kann ist Flagger. In diesem Vortrag wird anhand von Live-Demos gezeigt wie mit Flagger im Zusammenspiel mit Flux, Istio (oder einem anderen ServiceMesh) oder einem IngressController diese Deploymentstrategien umgesetzt werden können. Auch werden die Unterschiede zwischen Canary Deployments, A/B Testing, Blue/Green Deployment und weiteren Strategien erläutert und wann man welche Methode verwenden kann. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* Während unserer Meetups werden Fotos aufgenommen.

Let’s meet on the last day of February for a gentle, warm, and slightly unpredictable afternoon together. This meetup is for people who enjoy meaningful conversations, emotional awareness, and authentic exchanges, the kind that leave you feeling both lighter and more alive. What to expect A small circle of open-minded humans, with tea, coffee, or food in hand, sharing self-reflection, philosophy, psychology or simply ideas and inspirations that arise naturally in the moment. There is no fixed topic. The conversation flows on its own. To give you a sense, here are some topics that emerged last time: - If you have lived in different places and cultures for many years, can you still define your origin as where you were born? - How to find peace and calm (inspired by Indian philosophy). - If someone behaves differently from most people in a system, are they wrong? (I’ve shared my perspective on this topic [[click here](https://www.instagram.com/p/DTqk5t6Avy_/?igsh=MXBhemd5ZTE1dnFzcQ==) ], feel free to add your own in comments . ) - Where would you like to spend your retirement, and why? - How to position yourself as an expat in a country like Luxembourg. - Cultural differences around complaining: in some cultures it’s negative, in others it’s seen as necessary for change. - Human energy, presence, and “frequency” — and how we influence it. - … and more. Practical details Venue: Bouneweger Stuff Date: Saturday, February 28, 2026 Time: 15:00 – 17:00 Group size: 12 people ☕ Food & drinks: Everyone orders and pays individually (If you can’t attend, please cancel so someone else can take the spot.) If you enjoy authentic connection, gentle humour, openness to different perspectives, and conversations that have a life of their own - you are very welcome to join. ✨

**⚡ AI & Coffee – In-Person Meetup in Luxembourg** We’re hosting the next event on Sunday 8th March from 15h00-17h00 in Updown Bar (Downstairs) Based on the great feedback last time, feel free to bring your laptops if you’d like to show your work. People were very open to sharing approaches and projects, which sparked some truly deep conversations. Looking forward to meeting you all again, and also welcoming those who couldn’t make it last time. AI is moving so fast that it’s hard to keep up alone. The best way to make sense of it is by meeting others, exchanging ideas, and hearing fresh perspectives. That’s what this meetup is about. ☕ We’ll gather in a local café for open conversations about: * AI news and trends (what’s real, what’s hype) * Sharing projects, ideas, and feedback * Supporting each other and creating new stories * Building connections with like-minded people **Who’s welcome?** Developers, entrepreneurs, investors, mentors, students, researchers, creatives — and anyone simply curious about AI. **What to expect** * Casual atmosphere, no commitment, no pressure * The host will share small icebreakers and sparks of AI news * The rest is up to you: meet, talk, connect, and exchange The only cost is your own coffee or drink. Bring your curiosity and an open mind — and let’s build one of the most exciting AI communities in the area.

**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** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
