**🚀 Join our free Budapest Data Science Meetup!** In our first session, Tamás Németh from DataHub will explore the evolution of data catalogs into "Metadata Control Planes," explaining how authoritative context is the secret sauce for preventing "confident but wrong" AI agents. Then, Daniel Darabos, CTO of LynxKite will take us into the world of biotech, demonstrating how GPU-accelerated screening is fast-tracking drug discovery by targeting G-protein coupled receptors with unprecedented speed. **📅 Date & venue:** * **26 March 2026, Thursday, from 6 pm** * **Shapr3D Office 1054 Budapest, Akadémia u. 6. · Budapest** **Please note that the event's official language is English!

Building Datahub, the open-source metadata catalog. Previously led the data-engineering team at Prezi and worked on a platform to fulfill all of the analytical needs at scale. Tamas is also a committer in the Apache Gobblin project. Abstract: Traditional catalogs are no longer sufficient for today’s complex, decentralized landscapes. This session explores their transformation into Metadata Control Planes, the operational “central nervous system” for enterprise information. As AI agents replace humans as primary consumers, this infrastructure becomes the critical bedrock for Context Engineering. Unlike people, these autonomous systems act directly on the information they find without seeking clarification; they require authoritative context to avoid “confident but wrong” outcomes. We will demonstrate how to repurpose your existing lineage, quality signals, and business glossaries to provide the provenance and semantic clarity these models crave. Discover how to evolve a passive inventory into a high-performance engine for reliable, enterprise-grade AI. **Drug discovery with AI: Targeting G-protein coupled receptors with GPU-accelerated screening** Abstract: GPCRs are an important but difficult drug target. The receptor we are focusing on, called Mas, has an important role in regulating the cardiovascular system and muscle growth. A natural compound that activates Mas is in phase 3 trials for treating old-age muscle loss (sarcopenia). As it's based on a plant extract, only a limited supply can be produced. The search is on for a highly efficient, safe, synthetic alternative! Join us to learn more about our GPU-accelerated solution for scoring billions of potential drug molecules with a variety of models. \*\*[Daniel Darabos ](https://www.linkedin.com/in/darabos/)\*\*is the CTO of **[LynxKite](https://www.linkedin.com/company/lynxkite/)**.

Practice Buddhist meditation in the middle of Budapest! The meditation is suitable for beginners. Each regular meditation is guided and begins with a short introduction. (all together is about 30-40 minutes) Our regular Buddhist meditations have proven popular with people who want to integrate authentic Buddhist methods into their daily lives. For the modern lay person who is juggling work, relationships, and an active role in society, we teach a meditation that is easy to learn, and profound and powerful for experienced practitioners. The meditation originates from the Karma Kagyu tradition of Tibetan Buddhism. It has a cumulative effect on mind, leading to greater clarity and calmness. Fearlessness, joy, and active compassion are the result of regular practice of Buddhist meditation. * Do I need any special clothing? No special clothing needed. * Does the attendance cost anything? No, the meditation is free.

“Resentment is like drinking poison and then hoping it will kill your enemies.” ― Nelson Mandela **(In english!)** Throughout history, human societies have wrestled with division. When identity hardens into polarization, coexistence becomes fragile. Differences can escalate into civil conflict, deepening distrust and resentment that often persist for generations. Yet history also offers rare examples of a different path: moments when cycles of hatred did not spiral into further violence, but instead turned toward reconciliation. In this session we will explore **Ubuntu** — the African ethical philosophy that shaped the moral framework of leaders such as Nelson Mandela and Desmond Tutu. Ubuntu — “I am because we are” — proposes that identity is not purely individual but relational. Even those we oppose remain part of our shared collective. This insight may be the hidden condition behind successful reconciliations. Beyond South Africa’s transition from apartheid, we can examine other cases of reconciliation: the American post–Civil War, the reconciliation between France and Germany, Japan’s postwar transformation, and the peace process in Northern Ireland. **Introduction of guests (15 minutes)** We start with a short introduction of the guests. **Kérdések (1 óra 45 perc)** 1. According to Ubuntu why is hope better than optimism? 2. Are we living in a time of self-respect? 3. Can Ubuntu be applied to someone who opposes Ubuntu? 4. What happens when “we” includes people who reject your values? 5. How does Ubuntu work when conflict is on-going? 6. Can the strength of the collective sometimes go the wrong direction? How to avoid that? 7. Have you put yourself in the shoes of someone you deeply reject? 8. How can we compare the european reconciliation with the South African or North-Irish reconciliations? 9. What is more important for reconciliation: leadership or strong institutions? 10. Can forgiveness be compatible with justice all the time? Is there a point where forgiveness becomes injustice? 11. Why is truth so important in reconciliation? 12. Can reconciliation hold when material inequality persists? 13. Can ubuntu help to undo polarization? 14. How can we apply ubuntu to social media? 15. Is ubuntu a way of individual-to-social maturity? 16. Is polarization a symptom of moral seriousness — or moral immaturity? 17. Is polarization driven more by inequality or by identity? **RSVP:** Please confirm your attendance here on Meetup to save your space and if you cannot assist, yield your space to another person in the waiting list. We welcome donations from 400 HUF to keep the costs of the meetup (If Paypal doesnt work, dont worry, you can donate on location with cash, Revolut, or transfer)

Hello everyone, Welcome to the Monthly Book Club — the discussion edition of the Budapest Silent Book Club for those who enjoy reading the same book and sharing thoughts together. This March, we’ll be reading *The Body Keeps the Score* by Bessel van der Kolk. The book explores how trauma affects both mind and body, and how people can heal through a variety of therapeutic approaches. It’s a fascinating, sometimes intense read that opens the door to deep conversations about psychology, resilience, and the ways our experiences shape us. 🕕 Time: 18:00–20:00 – Group discussion about the book (no silent reading hour this time) 📍 Location: Altair (it’s just a plain-looking door with a sign on it) I’ll bring a few discussion prompts, but everyone’s thoughts are welcome.

Every Saturday at 8:00 PM, we gather in the city to share languages, cultures, and conversations. [[Click this whatsapp groupchat link to join](https://chat.whatsapp.com/CGM1Jm8JfNS291xA1zMobk) ] Our group is made up of friendly 20s–30s people — locals, expats, and travelers alike — who come together to meet new people and explore different ways of thinking. Whether you’re new to Budapest or call it home, this meetup is your chance to connect in a relaxed, open-minded space. Join us to swap stories, practice new languages, and build genuine friendships across cultures.

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. 6:30 to 8:00 pm. Main meeting and presentation(s). Topic: Type Annotations with John Cassidy We meet on the last Monday of each Month.

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!

We thought of one of the interesting things that can be enjoyed at this time of the year. We will be meeting at Immaculate Conception Catholic Church for a "Fish Fry" in Marian Hall on Friday, March 27th at 5:00 PM. It might be fun for you to experience what has become a tradition on the Fridays before Easter. They will have fried fish or baked fish, French fries and Cole slaw, as well as beverages, all for $16.00 for adults. They will have other beverages and desserts available for sale, as well. We have never tried this, and sometimes there are quite a few people at these events so we hope that we will be able to find each other easily. I'll try to have signs outside Marian Hall that Identify our group. We hope to have you join us!
