UNO #472
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

Testelt to Aarschot (21km)
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)

**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.

There are connections at xx:14 and xx:36 from Aarchot to Brussels, changing in Leuven and taking \~42 minutes to Central station.
**Specifics**

**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.
Deutscher Stammtisch in Präsenz
Liebe Freunde der deutschen Sprache,
alle, die gern deutsch hören bzw. sprechen möchten, sind eingeladen zum nächsten virtuellen Stammtisch. Wenn Ihr eine Frage oder ein Thema habt, über das Ihr gern sprechen möchtet, seid Ihr herzlich willkommen. Bitte meldet euch nur an, wenn ihr wirklich teilnehmen wollt!
Wir freuen uns auf den Austausch mit Euch!
Debate Night: Personal vs Corporate Ethics
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.

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
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.
Columbus Arduino Raspberry Pi Enthusiasts (CARPE) (Check Location)
Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration!
This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired.
**New to electronics or curious about tinkering?**
You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building.
While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

Join the local UX and Digital Design community for a casual monthly breakfast.
Look for us upstairs!
Columbus Code & Coffee 85 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you!
**What to Expect at the Intro Circle**
\~\~\~\~\~\~\~\~\~\~\~\~\~
Near the beginning of the event (1:30 pm), we do a standup:
* Organizer announcements, updates, and logistics
Round 1 - (7 secs max):
* Your name
* What you're working on
* What you can help others with
Round 2:
* Community events you wanna plug. If none, that's cool too.
Round 3:
* Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool.
After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
