*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 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!

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/

**🏛️ 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/) 👈

**Hi everyone!** I’m David, and I’d love to start a social bouldering club for anyone who wants to climb, hang out, and meet new people! I will arrange a meetup climbing event every 2nd week or once a month, at different climbing gyms around the city. The focus is on: • Climbing and challenging ourselves • Being social and building a fun community • Training together – all levels welcome I’ve been climbing for about 1.5 years, so I’m still in my learning phase, but I’m more than happy to help beginners get started and share the basics with anyone who’s new. **We will climb at Blocs and Walls @ 14.00 o’clock.** If people want, we might go for a drink or a bit of food afterwards. There will be a short warm up, focusing on climbing and mobility. If you want to join in on that, otherwise drop in when ever.¨ This time, since it is at Blocs and Walls, I can help people doing robe climb. But we figure that out when we get there :D **What Is Bouldering?** Bouldering is a type of climbing done at low heights — usually up to around 4–5 meters — **without ropes or harnesses**. Instead, there are thick mats on the floor for safety. There is an entrance fee and renting of climbing shoes, which you can rent at the location, and so cloth where you can be flexible. Bouldering is very social — people often help each other, share tips, cheer each other on, and have fun together. It’s perfect for meeting new people while getting a good workout.

**Founders Running Club** (FRC) brings founders, investors, tech, creative people and startup enthusiasts together for weekly easy runs and networking.

**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

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
