Let's continue the tradition and play UNO, everybody is welcome :) If you're on the waitlist please check your messages, especially on Sunday. If people drop off last minute I tend to message people on the waitlist to see who can come. We'll be playing at the lobby of Radisson RED, Brussels. The address of the hotel is: Rue d'Idalie 35, 1050 Bruxelles My number is 0471 45 55 02. Feel free to call if you cannot solve a physics question, cannot find the place or simply need a hug. I have quickly written a set of rules on how we play. It is assumed that the reader has a basic concept of the game. *** Setup: * Each player starts with 6 or 7 cards each (depending on total number of players) * A card is shown in play in the middle of everyone, this is known as the top card. Goal: * The goal of the game for each player is to get rid of all cards in your hand Rules: * Whenever you go from two cards to one card, you have to say "UNO". * Each player takes his turn one by one, initially going in the clock-wise direction * A card may be played if it matches the same colour or same number or same type as the top card in play * The two black cards (Draw 4 and Wild) can be played regardless of the top card in play. * Interruption rule: You may interrupt the general flow of the game (clockwise or counter-clockwise) if you have the EXACT same card as the top card in play. If you manage to play the card prior to the person whose turn it's supposed to be, then the game continues on from you in the same direction it was previously. (Unless the reverse card was interrupted, then the direction changes). * Draw2 or Draw4 cards can be played in accordance to the interruption rule. The following person after the interrupt has to take the accumulated number of cards. If however, cards have already been drawn AND seen by the person who was supposed to take the cards, then only the remainder of cards has to be drawn. * Once someone has no cards remaining in his hand, play stops and we start counting points. Points: * Number cards have the face value as the number of points. i.e. number 6 is worth 6 points, number 0 is worth 0 points, number 4 is worth 4 points. * Skip, reverse and Draw2 are worth 20 points each * Wild and draw4 are worth 50 points each

Drinking & Networking in Brussels. For newcomers, temporary in town - couch surfers and regulars to meet & socialize. What a better day to start the week than drinking & socializing starting on Monday evening?

A late posting but for those who are still free on Monday let's go for a hike from **Testelt to Aarschot** (\~21km, 160m elevation). We will return to the wetlands in the north-east of Vlaams-Brabant, not too far from Brussels, and explore an area we didn't visit for some time. At the end, we will hopefully find somewhere for an (optional) drink in Aarschot before taking the train back to Brussels. **The weather forecast is sunny and 14C, but prepared for a shower just in case. The path may be muddy and slippery in places so wear good shoes, preferably walking boots.** **We will walk at an average speed of 5km/h. This is quite fast.** We will walk both on paved and unpaved roads. I’ve never walked this route before, so it’s possible there are some mistakes in the planning. **You can find the GPX track here:** [https://mapy.com/s/relasemepa](https://mapy.com/s/relasemepa) (I may still update the route a bit) **Meeting point and train** We will meet outside Starbucks in **Brussels Central station at 09:00**. The train **T18022 (Bierges-Walibi & Ottignies)** leaves from **platform 3 at 9:12** (you can also join this train at Brussels Zuid at 9:07 or Brussels Noord at 9:18). We arrive in Leuven at **9:35** change on to the **IC 2608 (Aarschot & Genk),** leaving from platform 8 at 9:43. It arrives in Aarschot at 10:06. **Train tickets** \- Single Brussels to Testelt\, € 8 or € 4\.80 with Train\+ \- Single Aarschot to Brussels\, € 6\.90 or € 4\.20 with Train\+ You probably want to buy the Train+ card for the price of € 6 (1 month) or € 48 (12 months). It can be bought in the SNCB/NMBS app or at ticket machines. **Train back to Brussels** There are connections at xx:14 and xx:36 from Aarchot to Brussels, changing in Leuven and taking \~42 minutes to Central station. **Specifics** Distance: \~21 km Elevation gain: \~160 m Net walking time: \~5h Level: ***Easy*** **In the unlikely case of too bad weather, we may cancel a hike, even a few hours before the event. If this happens, we will of course update the Meetup website and send out a message to those registered. So, it is important to have access to either the [Meetup.com](http://Meetup.com) website and/or your email.** **What to bring** **\- lunch \- we will *not* stop at a cafe/restaurant for lunch** \- comfortable hiking clothes – waterproof hiking shoes \- extra socks to change \+ compeed for blisters \- water \(min 2l\) and enough food for the breaks \- sun protection oil\, a head and sunglasses OR a raincoat (please consult the weather forecast on [www.meteo.be](http://www.meteo.be/)) \- mosquito/tick repellent \- some money for drinks/snacks/etc **Basic rules** The number of participants is limited, so make sure that you RSVP only if you really intend to come. If your plans change, update your RSVP asap. This is basic courtesy towards others. Last day cancellations, no-shows and Internet warriors are not appreciated. Only people whose name appears on the main list may come to the hike. **Acknowledgement of member responsibility and release of liability** You are responsible for yourself and should be fit enough if you choose to take part.

6th April is a holiday ! So why not having a full afternoon of gaming there on that day ? If you feel likewise, then join this event! Unlike most of our events, this is a more improvised one : some attendees bring their games, and we decide on the spot what we'll play. You may also post your ideas of what you want to bring/play in the comments, to gauge interest among the participants. Outpost opens at 11:30, so you may come from that time, but you can also come a bit later if you wish. No real ending time, you may leave whenever you feel like to ! **Please RSVP to this event if you wish to come**. Do not come without having done so. It makes it easier to plan that way. Although you can arrive at any time, **please post your estimated time of arrival in the comments**. It will make it easier to organise the tables that way. **Don't forget to unsubscribe from the event if you aren't able to come.** Someone else might take your place in that case. Don't block it if you don't come.

**🚀 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.

**First time comers** Please make sure to read the rules and contact the organizer before! Otherwise you will be moved to waiting list. Apologies for inconvenience but we have to do it to avoid no-shows. **Games format.** 95% are double games (unless someone needs a break), typically 4 people play together 2 sets and then mix with players from other fields. We play with plastic shuttles - Yonex Mavis 2000 (which are provided). **Registration** If it's your first time, please send a private message to the host to confirm. No-shows are taken quite seriously because they unbalance the games a lot. Also once you register please keep an eye on you private messages, in case we need to contact you. **Players level** Having players with much less experience often unbalances the game making it much less interesting for more experienced players. We still try to be welcoming. As a rule of thumb, if you know what a "clear" is, you are welcome to join. (Note that on Sundays the attitude is a bit more relaxed than on Wednesdays, it's the weekend after all ;) ) Otherwise, feel free to get in touch with me (Timur) and we can see if we can arrange so you and existing players can have good experience playing. **Price and payments** The price of participation is EUR 8.95. Payment is on-site in cash, or via payconiq. Info provided during or shortly after the event. **Cancelations and no-shows** * Switches and cancellations are free of charge if done more than 50 hours before the start of the matches * If you cancel within the 50-hour window before the event starts, you will be placed on the wait-list for the next week's event, whether or not a replacement is found. If no replacement is secured, you'll still need to cover your share of the costs.

Meet and make new Friends after work.

Corporations shape much of the modern world, and behind these corporations are individuals: engineers, managers, marketers, researchers, and countless others whose work contributes, directly or indirectly, to the final product. This raises a fundamental question about responsibility. When a company produces something harmful, misleading, or ethically questionable, where does accountability lie? Is it confined to leadership and decision-makers only, or does it extend to every individual involved in the process? A developer writing code for a platform may not control how it is ultimately used. A scientist working for an energy company may not decide corporate strategy. An employee in marketing or administration may be far removed from the core activity that attracts criticism. Yet without these roles, the company could not function. This debate invites us to explore the nature of ethical responsibility within large organizations. Can morality be separated from one’s professional role, or does it inevitably follow from it? Are individuals morally responsible for outcomes even if they do not control them, or is responsibility something that belongs primarily to institutions? Join us as we examine the relationship between personal ethics and corporate structures, and question where responsibility truly begins and ends in the modern workplace. This debate will follow a British Parliamentary format with eight debaters split into **four teams of two.** Participants who wish to speak are highly encouraged to bring a paper and pen. You are welcome to participate even if you have no prior debating experience. We aim for debates that are respectful, constructive, and welcoming: * **Respect ideas and people** Listen actively, stay quiet while others speak, and debate arguments, not identities or beliefs. * **Be concise and civil** Keep questions short and relevant; avoid hostility, hate speech, or discrimination. * **Respect boundaries and time** No unwanted advances or suggestive behavior; arrive on time to avoid disrupting the debate. * **Follow moderators** They guide the discussion and ensure fairness.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

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
