*Talk by Claes Worm* `tatr` is a new tool written in OCaml for recursively traversing file-hierarchies and finding all indented trees of text that match your queries. Its design tries to be simple, powerful, elegant and general. A common action on the CLI is to search for all the files within some directory that contain a specific regular expression - e.g. using a mix of `find` and `grep` or tools that do both like `ripgrep`. These tools only match on lines, not on “sets of lines” or “related lines” or “trees of indented text” - `tatr` does this and filters the trees to only show the parts you are interested in. What formats can you query? Anything that contains lines of text that are related to each-other based on indentation. E.g.: * bullet-point based notes like markdown, wiki, org-mode or plain text * notes with *tags* * code that contains comments * structured configuration-formats like json, sexp, etc. When used with your notes; you suddenly get the opportunity to not only structure your notes by linking pages in a graph or tree - but also by tagging and logically relating “verbal arguments” via indentation.

Join us in the next AZUG meetup and learn how to tune your cloud database. **Hands‑on tutorial on Azure Database for PostgreSQL Flexible Server parameter tuning** PostgreSQL exposes hundreds of configuration parameters, but only a few dozen truly determine performance and resource efficiency. Tuning them correctly is notoriously difficult due to complex interactions and workload‑specific behavior. Traditional approaches—manual tuning or generic rule‑based tools—often fall short. In this practical workshop, participants will learn the fundamentals of server parameter tuning and get hands‑on experience using heuristics‑based open‑source tools such as PGtune to achieve meaningful performance improvements. We'll explore which parameters matter most, how PGtune's heuristics work, and why they influence performance. The session concludes with an introduction to DBtune Community Edition , an AI‑powered agentic tuning engine that blends heuristic rules with modern AI and ML techniques to deliver smarter, workload‑aware optimization. **Prerequisites: Bring your own laptop with a command‑line shell (eg, PowerShell).** If you are using a company laptop, please whitelist \*\* [http://app.dbtune.com%2A%2A./]app.dbtune.com\*\*. **About our Speaker:** Dr. Luigi Nardi is the founder and CEO of DBtune, a leading company driving advancements in AI, database systems, and cloud computing. Previously an associate professor of AI at Lund University and a research staff at Stanford University, Luigi's expertise centers around Bayesian methods and optimization theory and practice. Luigi's journey includes a post-doctoral position at Imperial College London and a role as a software engineer at Murex, following his Ph.D. program in applied mathematics at Université Pierre et Marie Curie in Paris in 2011. Luigi is a public speaker and prolific researcher, having co-authored more than 50 peer-reviewed papers at leading venues in machine learning and computer science. **Sponsors:** https://www.dewise.com/ https://codenode.dk/

Join us for an inspiring session exploring the frontier of "constructive" democratic technology. As traditional mechanisms for citizen engagement struggle against polarization and an algorithm-driven attention economy, how can we build digital public infrastructure that actually brings people together? Digital deliberation provides a new framework for our democracy. Rather than focusing on division, these tools allow us to map underlying consensus and foster collective sense-making across society. In this meetup, we move beyond abstract theory to explore the practical ways the Finnish Innovation Fund (Sitra) has successfully deployed citizen participation at scale, and look ahead to the new European Civic Tech Hub. We will dive into: * **The Power of "Voxit":** How Finland successfully scaled this open-source platform across more than 120 societal dialogues, utilizing AI and statistical clustering to map "Uncommon Ground" and find consensus. * **From National Labs to European Impact:** Insights from massive citizen dialogues—such as the "What do you think about AI, Finland?" campaign—and how they directly shape public sector rulebooks. * **The European Civic Tech Hub:** How the ongoing work to build a centralized hub under the European Commission's *European Democracy Shield* aims to solve the biggest bottlenecks in civic tech adoption, from procurement to GDPR compliance. **About the Speaker & Moderator:** **Sanna-Kaisa Saloranta (Speaker)** is a Specialist and Democracy Team Lead at Sitra's International Programmes. She leads efforts to scale democratic innovations that support collective sense-making, actively working to bridge the gap between Finnish open-source success and the wider European digital ecosystem. **Michael Jensen (Moderator)**, Co-founder of DemAI, will host the session and guide the conversation, drawing on his expertise in democratic AI to bridge the themes of the presentation with our audience's questions. Come prepared for a constructive dialogue on how we can learn from these approaches to build a more transparent, resilient, and connected democratic future in Europe. We look forward to seeing you there!

Fulfillment. Joy. – Do you know what it is? Do you feel it now? Many of us are living lives that have “just sort of happened”. We had a dream, a vision (maybe we still do) for what we wanted our lives to look like. Somewhere along the way, life took over and something else ended up happening. We made decisions, took a turn down a path, and now our life isn’t what we thought it would be. Or we’re living someone else’s life. Maybe it’s what our parent’s wanted for us. What we believe our partner or a potential partner might want. Or maybe it’s what we believe we need to do and have to be happy. I was one of these people. My life checked all the boxes for what I thought I needed in order to be happy. And still, I wasn’t. Join me for a coffee talk on what it means to live a Life By Design. Where your choices are deliberate and based on your authentic, true self. What you have to let go off to achieve this (hint: the notion that vulnerability is a weakness and feelings of fear and guilt) and who you will become in the process.

We are a group of people meeting on Tuesdays to socialize around cooking and eating together. Usually around 40-50 people. Many are international students, but also other people join. The foodclub exist independent of Meetup, we invite you because we have room for a few more people. The food is vegan and made from donated leftover veggies from a local greengrocery. The place has originally hosted leftwing activist groups, and many of the people joining are also involved in political groups. If you want to join for chopping and cooking, we will be doing that from 3 to 6 pm. It is possible to join part of the time. From 6:30 to 8pm we are serving food. Donation around 30 kroner. If you are helping out some hours, chopping, cooking or cleaning, you can eat for free. From 8 to 9 - 9:30 pm we are cleaning up the place. We hope to see you in our lovely foodclub <3

Join us for another evening of deep dives into data engineering! This time, we are hosted by **[Heyra](https://heyra.io/)** for two talks that explore the practical side of the "Agentic" shift in data workflows and the high-performance internals of data transfer with Apache Arrow. As always, there will be food, drinks, and plenty of time to network with fellow data engineers in the Copenhagen community. Based on the style of your previous events and the details provided, here is a draft for the upcoming **Agentic data engineering, beyond the hype** *Kilian Tscherny, Lead Data Engineer @ Heyra* Data engineering is changing fast, and the teams getting ahead are the ones rebuilding their workflow around agents instead of just bolting them on. In this talk, Kilian will cover how the team at Heyra has adapted to this shift, sharing real-world examples of how agentic workflows can move beyond the hype to provide actual architectural value. **Taking Flight: Zero-Copy Data Transfer at Scale with Apache Arrow Flight and Friends** *Anders Bogsnes,* *Head of Investments & Trading Engineering @ Nordea Asset Management* We all love Apache Arrow in our DataFrames and DuckDBs - but have you considered how the data is ending up on your machine? Arrow Flight and friends was designed as a way of enabling end-to-end native Arrow communication and in this talk we will go through the motivations behind the Arrow Flight protocol, introduce some of the derived protocols, and we end by building an Arrow Flight server from scratch and demonstrating how to interact with that server from a client. **Agenda** * **18:00:** Doors Open & Networking * **18:20:** Welcome from Copenhagen Data Engineering & Heyra * **18:30:** Agentic data engineering, beyond the hype – Kilian Tscherny * **19:00:** Food, Drinks & Networking * **19:30:** Taking Flight: Zero-Copy Data Transfer at Scale – Anders Bogsnes * **20:00:** Networking & More Drinks

✨We’re excited to invite you to a new Barrel AI 🐒🐒 event — this one is shaping up to be one of our most epic yet ✨ We’ll be given a presentation and speach by an eminent AI expert and ambassador, **Dr. Michael Green**, alongside our recurring **AI Release Radar**, where we highlight the latest AI/ML releases and news. As always, there will be great opportunities for networking — plus pizza and drinks. This event will also be hosted at our new home for future events: **Fyrtornet / Drivbänken**, right in the heart of Hyllie, Malmö. **📅AGENDA** 17:30 – 17:45 Arrival & initial networking 17:45 – 18:00 Welcome by Barrel AI organizers 18:00 – 18:20 AI Release Radar 18:20 – 19:00 Dr. Michael Green – Talk & Q&A 19:00 – 19:30 Pizza & networking **🚀 THE WARM-UP: AI RELEASE RADAR** Before the demo, we will kick things off with our AI Release Radar and scan the latest happenings in the AI community — LLM drops, AI/ML white papers, and the news that actually matters to AI Engineers & Developers. **🎓 SPEAKER INTRODUCTION** Dr. Michael Green builds AI systems designed to make decisions under uncertainty, using Bayesian machine learning and probabilistic AI—because real-world environments rarely provide perfect information. Models that fail to account for uncertainty often become fragile when deployed in complex settings. He is the founder of two Copenhagen-based AI companies applying these principles where decision-making truly matters: *Alviss AI* and *AI Alpha Lab.* Alviss AI is a marketing science platform that helps organizations optimize advertising, media investments, and growth through a combination of probabilistic modeling and modern machine learning. AI Alpha Lab is a research-driven initiative focused on financial markets and systematic investing, leveraging probabilistic AI and quantitative methods. Their AI-driven fund, trading on Nasdaq, has achieved performance surpassing many index funds. Michael is also a strong advocate for digital and AI sovereignty, with a focus on strengthening EU-driven AI ecosystems—a topic he will also touch upon. 🗣️**TALK DESCRIPTION** At the upcoming Barrel AI event, Michael will take a deep dive into the technical architecture behind his systems, exploring how uncertainty-first and physics-inspired neural networks are applied in high-stakes environments. Financial markets are unforgiving—there are no second chances, no re-runs with a different random seed. In his talk he will tell the story of building the model that now runs AI Alpha Lab’s fund, and the hard lessons learned along the way. It starts, as these things often do, with 36 million going up in smoke 🔥💸.

ENG The topics we will vote to discuss are Emotional beliefs, Choices and acceptance and Jealousy. 2 emotion topics and 1 personal challenges topic to vote for discussion. We will try as a group of random people to sit down and talk about emotions or personal challenges. Not necessarily to find a solution or an improvement, but to share perspectives and maybe discover new perspectives. Some people like to talk, some like to listen, at the start of each event, declare if you would prefer to participate in the discussion or prefer to listen in and chime in with an occasional question. If only danish speaking people are coming we will speak danish, if there are non danish speaking people coming we will speak English. DK De fag vi skal stemme om at diskutere er Følelsesmæssige overbevisninger, Valg og accept og Jalousi. 2 følelse fag og 1 personlige udfordringer fag at stemme mellem at diskutere. Vi skal prøve som en gruppe af tilfældigvis folk at tale om følelser eller personlige udfordringer. Ikke nødvendigvis før at finde løsning eller en forbedring, men før at dele perspektiv og måske finde nye perspektiv. Nogle personer kan lide at tale, nogle personer kan lide at lytte, I begyndelsen af hver diskussion, erklære hvis du vil deltage I diskussionen eller lytte og komme med nogle spørgsmål under diskussionen. Hvis det er kun dansktalende der kommer så snakker vi dansk, kommer det ikke dansktalende så snakker vi engelsk.

You’ve thought about it. Reflected on it. Maybe even talked about it… But how do you actually *move forward*? In this practical, hands-on workshop, we focus on one thing: 👉 turning ideas into small, concrete actions You’ll: • Choose a direction that feels interesting (not perfect) • Turn it into a simple, real-world experiment • Plan when and how you’ll take your next step No big life decisions. No pressure. Just a clear, doable action you can take right away. 🧭 This is the 3rd session of a 6-part series—but you’re welcome to join even if it’s your first time. Progress starts small.

# Tired of dating apps or surface-level social events? This is different. Relational Labs is a guided connection experience for singles who want more honest, playful, emotionally intelligent interaction — without performance, pressure, or endless small talk. This is not speed dating. Not networking. Not “pitch yourself to strangers.” It’s a facilitated relational container rooted in psychology, emotional intelligence, attachment work, social dynamics, nervous system awareness, and real-world human connection — made practical enough that you can actually live it instead of reading another 50 books about it. ## What happens • A 2-hour guided online relational experience • Real-time connection exercises designed to create authentic interaction • A format that adapts in real time to whoever is present • Optional participant-led in-person continuation afterward • WhatsApp connection thread after the session ## This may be for you if: • You’re tired of shallow or repetitive social spaces • You want deeper connection without forced intimacy • You enjoy personal growth, psychology, communication, or relational work • You’re open to meeting people in a more intentional way ## Important This experience runs with whoever is present and takes its own shape each time. Sometimes expansive. Sometimes intimate. Both are the real thing. Booking happens through our website. 👉 Reserve your spot: [https://consciousconnectionsclub.com/join](https://consciousconnectionsclub.com/join) Optional in-person continuation: same day or within 48 hours depending on the city Most people come alone. People often leave surprised by how quickly strangers can feel human, warm, honest, and real. Sometimes awkwardness turns into ease. Sometimes curiosity turns into chemistry. Sometimes people simply remember what it feels like to actually connect again.
