Ever find yourself mulling over life's big questions after a long day? Like what it means to live well, or why anything matters at all? You're not alone! Come pull up a chair, grab a drink, and join a friendly bunch of curious minds for some thoughtful conversation. This group is all about creating a relaxed, welcoming space where we can explore meaningful questions together. No lectures, no gatekeeping, just a chance to hear different perspectives, share your own, and maybe walk away with a few new ideas (or at least a better question than the one you started with). No philosophy background required, just an open mind and a willingness to chat (or just listen). Each session loosely centers on a topic picked by the group from suggestions we all pitch in (via a dedicated WhatsApp group). Themes can range from love and hate, to society and politics, family and friendship, harmony and conflict, and beyond. For those interested, you're welcome to join the WhatsApp group - just ask Nicolas, Det or Reinier at one of the meetings.

🤝 Comment améliorer le vivre ensemble ? 🌍 **Dialogue philo** Dans un monde où les divisions semblent s’accentuer, comment recréer du lien, du respect et une véritable fraternité ? Le “vivre ensemble” ne se décrète pas : il se cultive, jour après jour, par une meilleure connaissance de soi et une ouverture sincère aux autres. Lors de ce dialogue philosophique, nous explorerons ce qui favorise l’harmonie entre les individus et les communautés, à la lumière des sagesses d’Orient et d’Occident. Un moment d’échange accessible à toutes et à tous, dans un esprit d’écoute, de réflexion et de bienveillance. ✨ Venez avec vos idées, vos questions, et la curiosité d’apprendre des autres ! Tarif : 5€ (boisson comprise)

Spend time in the company of other writers putting pen to paper, or fingers to keyboard. Work on your current project or start something new. If you are fresh out of inspiration a member of the Wordcraft Collective will be ready with a prompt to get you going. You can use that to unlock your creative brain before moving back to your own project or run with it. Who knows where the story will take you? Arrive when you like, leave when you like, or join us for a drink in the bar downstairs afterwards. Location: Pianofabriek, Rue du Fort 35, 1060 Saint-Gilles.

Hello, readers ! In January we are reading The Vulnerables by Sigrid Nunez. ***Please note our new venue - Maison de Quartier Malibran, Rue de la Digue 10, 1050 Ixelles - and our new start time of 11am.*** More details on this change of venue will be sent soon in a separate message. **Please keep your RSVP up to date** and happy reading!

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.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group × DevOps Columbus** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS, Columbus HashiCorp User Group, and DevOps Columbus meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/azure-cbus-2026/

Welcome to Drunken Philosophy, a casual, curious, social discussion club. Optional topic for this meet up: Is life a dream? Dreams feel real while they last. Could life work the same way? How do we know we’re awake, and what follows if we can’t be sure? Let’s kick that around over a around of drinks: • What makes something feel real: continuity, shared evidence, or meaning? • How would you tell you’re awake (reality checks, memory, other people)? • If life is dreamlike, what becomes of free will and responsibility? • Is identity a story we keep telling—who’s the narrator? • Are we author, actor, or audience in our dreams and how would you tell? • Does art/film reveal reality or replace it? No lectures. Friendly crowd. Drop in for one drink and stay if it’s fun.
