Distributed Systems

**🚀 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/)**.

“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.

El objetivo de este encuentro es romper el hielo, hablar de las historias que nos gusta escribir, de por qué escribimos, de los libros que nos gusta leer, de qué dificultades encontramos al enfrentarnos al folio en blanco y de qué esperamos del grupo. En definitiva, se trata de conocernos como personas para entendernos como escritores. No importa si has escrito diez novelas, cuatro cuentos o el precioso título de un poema sin versos. Aquí todo aspirante a juntaletras es bienvenido.

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.

Join us for the new session of our discussion series **“A Night With…”**, where we dive into timeless myths and their universal messages. Following our last session, where we explored the duality of Apollinian & Dionysiac, this the time to delve into the journey of Orhpeus. **What to expect:** * I will open the meetup with a short introduction to Orpheus’ myth and share (or suggest) a few possible interpretations and connections. * After that, the floor is yours! Bring your thoughts, reflections, and any links you see between this myth and other domains, e.g. literature, art, philosophy, psychology, history or even your own creative work. * If you’re an artist and your work resonates with the divine twins' story, feel free to share it with the group. **Before the event:** Take 5 minutes to read the quick snippet of Orpheus’ myth (provided below👇🏽) and think of: * A book, artwork, or personal reflection that relates to her story. * Any modern parallels or insights you’d like to discuss. This is a space for **open dialogue, creativity, and shared exploration**. ### **🫧The story of Orpheus in Brief** **🎼Orpheus is the legendary poet–musician** of Greek myth, famous for playing the lyre so beautifully that animals, trees, and even stones were said to be **moved by his song.** He marries Eurydice, a nymph (or mortal woman in some versions), and their happiness is brief: Eurydice dies suddenly, most commonly after being bitten by a snake while fleeing danger or wandering in the fields. Stricken with grief, Orpheus refuses to accept her death. **He descends alive into the Underworld to bring her back.** There, his music softens the hearts of the rulers of the dead, Hades and Persephone. Moved by his devotion and the power of his art, they agree to release Eurydice, on one condition: Orpheus must lead her upward to the world of the living without looking back at her until they have both reached the surface. Orpheus begins the ascent, hearing her footsteps behind him but unable to see her. Near the exit, at the threshold between darkness and daylight, **doubt and longing overwhelm him**. He turns to look. In that instant Eurydice is lost again, fading back into the Underworld, unreachable. Orpheus tries to follow, but the passage is closed to the living; he is forced to return alone. After this second loss, Orpheus withdraws from love and society. In many versions, he is eventually killed violently (most famously torn apart by maenads). Even then, the myth insists that his song persists: his severed head and lyre continue to “sing” as they drift downstream, and the lyre is later placed among the stars as a constellation. 📃📜**Principal ancient sources:** * Plato, *Symposium* * Apollonius Rhodius, *Argonautica* * Virgil, *Georgics* * Ovid, *Metamorphoses* * Pausanias, *Description of Greece* * Hyginus, *Astronomica* * | | | --- | |

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

**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.

WQC has weekly Thursday night social nights at the Westerville Java Central. Come and grab a coffee and connect with the community: low stakes, chill environment, and tasty drinks. No registration is required; come as you are.

We're bringing a little friendly competition to the Columbus ServiceNow community while highlighting the cool things people have built on the platform. Five presenters will take the stage to showcase something they've built, solved, designed, or imagined on the ServiceNow platform - and a panel of judges (plus YOU, our amazing audience) will score them live. So basically, America's Got Talent but make it ServiceNow's Got Talent. Bring a notepad if you'd like 'cause you'll definitely be learning something new. Each presenter gets 10 minutes max to wow the crowd with: • A demo • A real-world business solution • A bold idea • A UX transformation • Or a creative use of the platform Judging Criteria: 🏆 Business Value 🚀 Innovation ✨ User Experience This event is about celebrating ideas, sharing knowledge, and showing how ServiceNow can drive both business impact and meaningful user value. Come learn. Come support. Come get inspired. Refreshments and bites will be provided. And maybe next time… you’ll be on stage.

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081
