*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.

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

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
