Software Architecture

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/

**This session is part of Global Azure 2026** Azure Skåne invites you to a double session. This time we have on stage **Venicia Solomons** \(aka Cyber Queen\)\, Cloud & AI Security at Microsoft \| CISSP and our own **Nikos Delis**, Microsoft MVP for Azure & Iot. **Agenda**: * 17:30 - 17:45 Meet & Greet * 17:45 - 18:30 Session 1 - Venicia Solomons * 18:45 - 19:30 Session 2 - Nikos Delis * 19:30 - 20:30 Mingle **Session 1 (by Venicia): Governing AI Apps and Agents - The Microsoft Approach** Every organisation is racing to deploy AI agents, and most are quietly inheriting a security problem they haven't named yet. By 2028, there will be an estimated 1.3 billion AI agents in the world. The old playbook doesn't stretch that far. In this session I'll share what I'm seeing in the field: why AI security isn't traditional security, and why every agent needs an identity, because that's what will define how we govern and manage them. At the core of Microsoft's approach is Agent 365, extending Purview, Entra, and Defender into the agent world so you can actually discover, protect, and govern what your business is building. Expect a few practical things you can take back to your team. **Session 2 (by Nikos): Architecting Agentic Systems Like a Grown-Up** What does “agentic” look like in a real codebase? In this deep dive, we’ll architect goal-driven systems using **Microsoft Agent Framework**—covering tool orchestration, planning cycles, state management, multi-agent composition, and governance. We’ll apply classic engineering principles to systems that reason, act, and adapt.

Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at our Copenhagen Shut Up & Write! sessions. Be it a book, blog, script, essay, dissertation, résumé, melody, poem, or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: - 15 minutes of hellos and getting settled; maybe some quick intros. - Then, the timer starts! : writing for 1 hour. - After the hour is up... chat / take off / keep writing, if you're on a roll. OPTIONAL SOCIALIZING happens once the hour of writing is complete. Writing can be very solitary... connecting (and sometimes even commiserating) with other writers is a cool thing. It's best to be on time, but BEING LATE IS ALSO OKAY: just show up and get settled, then check in with us after the session. (We’ll be the ones with the small Shut Up & Write! sign.) If you were on time, please be willing to make room for the friendly latecomer. What Should I Bring? Whatever you need to be able to write! Bring earbuds/earplugs if you want to block the cafe’s overhead music or the occasional conversation by other patrons.

*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. [https://github.com/rand00/tatr](https://github.com/rand00/tatr) [https://r7p5.earth](https://r7p5.earth) *As usual, there's mingling at the local bar after the talk.*

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

# 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.

**🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 **📓 HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 19:00-19:15 - People arrive and chat, get to know each other before the ‘official' start. * 19:15-19:25 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 19:25-20:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 20:45-21:00 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo. * 21:00 - The official meeting is over but it’s a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other. **🧧PRICING?** Practical Philosophy Club is FREE to attend! We just ask that if we are meeting in a café, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though! **💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** 🗣 “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * ​What will we talk about? What's the topic? ​The topic for the week is shared every Sunday in the Whatsapp group. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX). * Do I need to study or read anything to attend? No preparation is necessary. This isn’t a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it, but it's not required. * Is there a specific philosophy that Practical Philosophy is focused on? The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * Is it mostly men that attend? Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * Can I come alone? Of course you can, we encourage it :) * Can I be late? Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation. * Where do you meet? The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/). 🤝**POLICY** To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group. Practical Philosophy reserves the right to enforce this policy at its discretion to maintain a safe and respectful environment. **PRACTICAL PHILOSOPHY - Making Philosophy Available To All. ✨** Practical Philosophy hosts weekly, in-person meetups in 25+ countries, including Canada, Spain, Japan, Mexico and many more! 🗺️ \*\*\* Join our [Whatsapp group](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX) 👈 Follow us on [Instagram](https://www.instagram.com/practicalphilosophyclub/?hl=en) 👈 Our [website](https://www.practicalphilosophy.club/) 👈

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. 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
