**🚀 We're thrilled to announce the next Cloud Native Meetup @ ING!** Come join us for an evening of talks, great conversations, and good food. Expect fresh insights, real-world stories, and the kind of hallway chats that spark your next big idea. **Agenda** 🕕 18\.00 — Doors open \| Food & drinks 🎤 19.00 — Welcome 🔐 19.15 — What I'll Tell My Kids About K8s Security *(Lars Lefebvre, ING)* 🚀 19.45 — K8s-wish and other LLM adventures *(Andrew Yourtchenko)* ☕ 20.15 — Break ⏳ 20.30 — Kubestronaut Panel 🤝 21.00 — Networking **Getting here** **No on site parking available**, instruction on how to get there [over here](https://drive.google.com/file/d/1FYT8vBU513koHhvOyqW8tQshbzAhlzQ_/view?usp=sharing). **If coming by car, please only refer to the public car park instructions.** Access via entrance A, then follow the signs. **Sessions:** **Session 1:** **What I'll Tell My Kids About K8s Security (Lars Lefebvre, ING):** What I'll Tell My Kids About K8s Security is a creative and story-driven talk that makes Kubernetes security approachable — even for those who aren't deep in the weeds of K8s. Framed through metaphors and everyday analogies, the talk explores complex security challenges in a fun and memorable way. In the second half, I'll share the story behind an open source tool we built at ING to help teams uncover and understand real-world security issues in their clusters. *Bio:* Lars is a dedicated Cloud and Application Security Engineer with a strong background in the Cloud Native stack. He’s experienced in managing multi-cloud environments, promoting cloud-native practices, and enhancing security measures in software development lifecycles. **Session 2:** **K8s-wish and other LLM adventures (Andrew Yourtchenko)** Can we use LLMs to avoid writing YAML? This talk explores two approaches — a single-shot LLM call and a full agentic loop — using two open source projects, and what each gets right and wrong. *Bio*: After 25 years at Cisco across three lives — TAC Security, IPv6 technical marketing, and high-performance networking software — Andrew is now building open source agentic AI tools and doing occasional consulting. He is a coauthor of DHCPv6 and other RFCs, and holds 4 US patents. **Session 3: Kubestronaut Panel** *30 minutes \| Q&A* Meet a panel of Kubestronauts, some even Golden. We'll kick off with a quick intro to what a Kubestronaut (and Golden Kubestronaut) actually is, then dive straight into an interactive Q&A. Hear about their journey, what the grind really looks like, and what they'd do differently. This session is all about the conversation. *Bio Olivier Calzi (Golden Kubestronaut):* From pulling Ethernet cables as a student in France to becoming a Golden Kubestronaut, I have spent 10 years learning the stack from the ground up. Now a Cloud Native Expert with 15 CNCF certifications, I focus on SRE and infrastructure architecture. I'm a firm believer in the "work-study" model and a lifelong student who still finds engineering deeply fun. *Bio François Duthilleul (Golden Kubestronaut):* François Duthilleul is a Principal Solutions Architect at Red Hat, leading the security domain in the EMEA Telco CoE, co-author of the OpenShift Security book, and contributing to O-RAN and Sylva standardisation. The first Belgian Golden Kubestronaut and 2025 Top SSA, he brings 15+ years of network cloudification experience — and you'll find him at rock concerts, on a road bike, or talking cloud-native over a craft beer. *Bio Evelien Schellekens (Kubestronaut):* Evelien is a Principal Solutions Architect at Elastic. She enjoys sharing knowledge through public speaking and interacting with the technical community. She’s passionate about observability and open source technologies like Kubernetes and OpenTelemetry.

Après l’hiver, la peau paraît souvent plus terne, plus fatiguée et en manque d’éclat. Lors de cet atelier, nous verrons simplement pourquoi cela se produit et comment relancer naturellement la peau. Nous commencerons par une explication claire des besoins de la peau après la saison froide, puis nous passerons à une pratique guidée : • Démaquillage et nettoyage en douceur • Masque éclat (vitamine C / acides de fruits) • Application de sérum et de crème L’objectif est de vous faire ressentir les effets sur votre peau, tout en comprenant l’importance de chaque étape. Pour finaliser, je partagerai ma vision holistique de la peau : les produits sont essentiels, mais la vraie différence se joue aussi au niveau du “terrain” (stress, inflammation, équilibre global). Ce que vous allez recevoir : • Une expérience concrète et sensorielle • Une routine simple à reproduire chez vous • Une invitation à aller plus loin avec un diagnostic de peau personnalisé Rituel skincare guidée par Magali ,facialiste holistique Prix :30€ Uniquement 10 places

This is an open Circle for anyone and open to constellate on any subject. It's a good way to get started if you've been wanting to see what Constellations is all about. We will start with some bodywork exercises and then there will be time for three Constellations on any topic. ​A Constellation is a means for accessing the timeless map you hold within, linking the past to the present and the present to the future. It's a tool to find the origin of the problems we face today such as repeated patterns, blockages, relationship difficulties or health concerns, to name a few, and has the power to reveal hidden dynamics not visible to the normal eye. Then a healing exchange takes place and steps are taken to free you from the past and put you on a road to freedom, understanding and authenticity for your future. ​There are two ways to participate, either as a participant or Space Holder in the Circle or to bring a topic to constellate as an Issue Holder, which is limited to three places. Although one person will bring a subject to constellate, everyone participates. A Constellation is a Healing Circle for all who attend. ​ Price for Space Holders: 50 Euros (12 spots) Price for Issue Holders: 165 Euros (3 spots) ​Date: Sunday, April 12th ​Time: 3:00 to 7:00 pm Location: Shanti Home: Rue Darwin 8, Brussels 1190 (Forest) ​\*There are three spots available for Constellations. You must have attended a Circle as a Space Holder before constellating an issue. \*Spots are limited for both roles to ensure enough space in the room, although the room is very spacious. *Modified price for students or if you are unemployed. Write me if this is your case.​* Payment must be made beforehand. You can register either to the following account or pay by credit card or PayPal by following the link to the website.

Here, there will be no subject set in advance, instead **all participants are welcome to join at any point and at any level, from beginner to expert**. Beginners will be guided though the basics (C programming, how to use measurement tools, soldering, PCB design, etc…) and can get advice on what tools and kits to start with, others can come with their own projects to get help or share some knowledge. ## Requirements * Bring your own laptop (Windows, Linux or Mac) * Any microcontroller/dev kit to develop your project(s). If you are a beginner and don’t know what to buy, come and we’ll find the best starter kit for you ! * A strong desire to learn stuff, good mood and some patience !

Need some quiet time for reading? Want to share the experience with others? Join us at the charming venue of The Sister Café to read in the company of others. It’s alone, but also together, get it? We read for an hour and a half, then chat over a drink. This is a free activity except for the price of the drinks you're consuming.

Making new friends in a new city doesn’t need to be a struggle at all.

Welcome to our weekly event in the upstairs room of The Sister Café, rue Chair et Pain 3, one block from the Grand Place. Please get there early enough to order your drink at the bar first. Thank you! After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations. Past questions have been wide and not confined to academic philosophy: What is a genuine friend? Is social media turning us into emotional zombies? Do we lose some of the experience of things by defining them? Are we driven by sex? Is loneliness a personal failure? Is morality relative? **Crucially, be kind and respectful and generous** in your disagreements; remember how much you personally enjoy someone else proving you wrong before celebrating your cutting counterexamples.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

This group is brought to you by the Dianetics and Scientology life improvement center.

AI is changing how art is made. But when does it stop being your work and start being the machine’s?
