Join our next meetup on June 25th! We will have 3 talks and will share some food and drinks while networking **Location:** Infrabel, Rue des Deux Gares 82, 1070 Anderlecht, Belgium **Agenda:** 17:45 : Doors open 18:00 - 18:40 : Drinks and pizza 18:40 - 18:45 : Welcome 18:45 - 19:00 : Elastic @ Infrabel 19:00 - 19:15 : Real life never-seen-before railway project 19:15 - 19:55 : From unknown and raw to real value 19:55 - 20.20 : What’s new in Elastic v9 20:15 : Wrap up **Talks:** **Elastic @ Infrabel** In this presentation, we will explain how Infrabel uses Elastic today and how it supports our current needs. We will briefly outline some future optimizations and the integration of OpenTelemetry to further strengthen and extend our Elastic platform. To showcase how we use Elastic for addressing real business use case, we will demo a never-seen-before application build in collaboration with Elastic Belgium. *Safia Souabi – Big Data Engineer at Infrabel* *Olivier-Désiré Muhimpundu – Big Data Engineer at Infrabel* **Real life never-seen-before railway project** *How Elastic helps ensure the punctuality of rail services by detecting and correlating events in real time to anticipate disruptions, ensure operational continuity and optimise the flow of rail traffic."* *Vanessa Coeurnelle – Cyber Resilience Data Analyst at Infrabel* **From unknown and raw to real value** In this talk, Chris shares how he transformed a legacy log ingestion pipeline into a structured, scalable, and insight-ready ELK-based system. Starting from loosely indexed XML/SOAP logs with minimal configuration, the project required rebuilding the data model to handle multiple message types, complex nested structures, and inconsistent field representations. Without the luxury of a full upfront redesign, Chris adopted an iterative, data-driven approach: combining exploratory analysis with dynamic mapping strategies to progressively shape the data into a usable format. He will discuss how this led to the design of flexible ingestion pipelines, including XML parsing, normalization, and generic handling of heterogeneous payloads. The talk also covers practical techniques for managing sensitive data, reducing storage overhead, and improving query performance—such as selective data retention, hashing and fingerprinting strategies, and the use of data streams. Finally, Chris will touch on how structuring the data effectively enables higher-level capabilities like anomaly detection and automated alerting. This session is aimed at practitioners dealing with messy, real-world data and looking for pragmatic ways to make Elasticsearch pipelines more robust, maintainable, and valuable. **Bios** **Christoph Evers** is a Senior Data Scientist and Data Engineer based in Brussels, with over 15 years of experience in data systems, search technologies, and analytics. He has been working with Elasticsearch since its early days, contributing to the project between 2010 and 2012 and applying it extensively as a search engine, document store, and log ingestion platform. At OpenLex, he designs and builds advanced data solutions for legal research, including full-text search engines, NLP pipelines for entity detection and anonymization, and large-scale analytics systems. His work also includes operating and optimizing ELK-based observability stacks in Linux and Docker environments. Previously, Chris held roles spanning software engineering, data science, and R&D leadership across sectors such as social media analytics, mobility and market research. His experience combines hands-on engineering with business-oriented data applications, delivering scalable systems and actionable insights for both startups and multinational clients. He mainly focuses on search relevance, data observability, and the practical use of ELK in production environments. **Olivier-Désiré Muhimpundu** is a Data Engineer at Infrabel, where he has been working for more than three years on large-scale data platforms and data projects.

**Somatic Movement** is a powerful method based on principles and wisdom from Eastern movement practices, such as yoga and Tai Chi, as well as Western techniques and insights from neuroscience, trauma therapy, and burnout recovery. The goal is to activate your body and brain by allowing energy to flow through your system without overloading the nervous system. This is achieved through gentle, intentional movements, stretches and exercises, but also by increasing awareness and sensory perception — both internally (within ourselves) and externally (of our surroundings). Combining tension-releasing stretches, easy flow-restoring exercises (using trees, branches, logs, stones, hills...), doing silent or touch meditations and playful authentic relating games, we're able to release a lot of stored tension and start to feel free, open-hearted, unassuming and adventurous again. The 2h-sessions focus on gradually increasing physical resilience, but include emotional and energetic aspects as well to restore balance in body, mind and spirit. There is no competitive stake, there are no extremes or high-intensity actions involved. But we do sometimes challenge our personal comfort zones a bit, sliding in and out, bumping into some limiting belief or conviction we might carry within. We learn by looking at things from different perspectives. The sessions are guided by seasoned therapist Ken. For more info on his practices, please visit: www.nieuwegrond.be **PRACTICAL** This is a free introduction session for you. But since this is a professional practice, where paying people might participate as well, we can only offer this once. If you wish to continue afterwards, you can talk to Ken personally or book through his website mentioned above. The session starts at 10h sharp and ends at 12h. Meeting and end-point is always Parking Forest Playground Everzwijnbad, Weertsedreef 16, Oud-Heverlee at the border of Meerdaelwoud. Please read the location description well, Google Maps can be a bit tricky. Since we're in the forest and will connect with trees, branches, soil etc, please make sure your clothes can handle this. If you wish, you can bring some water and small towel for comfort, but it's not a must. Please be aware that the organizer can not be held responsible for any damage or losses you might suffer. A safe environment is a priority for everyone. The event will be cancelled only when the weather really doesn't allow it. If you have any other questions, please don't hesitate to ask via personal message. We hope to see and connect with you there! Ken

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 10:00 on Wednesday morning. Be it a book, essay, dissertation, article 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: 10:00 - SESSION: quick intros. 10:15 - timer starts: write for 1 hour. 11:15 - (the end) check in.

This workshop series is a **follow-up to the ESP32 Robotics workshop**, but with a different concept. Here, there will be no subject set in advance, instead **all participants are welcome to join at any point and at any level, from beginner to expert**. Beginners will be guided though the basics (C programming, how to use measurement tools, soldering, PCB design, etc…) and can get advice on what tools and kits to start with, others can come with their own projects to get help or share some knowledge. ## Requirements * Bring your own laptop (Windows, Linux or Mac) * Any microcontroller/dev kit to develop your project(s). If you are a beginner and don’t know what to buy, come and we’ll find the best starter kit for you ! * A strong desire to learn stuff, good mood and some patience !

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. 6:30 to 8:00 pm. Main meeting and presentation(s). Topic: This month Chris Pazsint will be talking about Agentic Coding. How does one use CLI Based Agents, and Agentic IDEs such as Cursor, Kiro, Antigravity? How to include agentic coding plugins for IDEs you already love such as Visual Studio Code. We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact Central OH Python at centralohpython@gmail.com

These meetings will be a building block approach to learning photographic mastery over three disciplines: Mechanical Mastery (MM) - 13 weeks of the series Exposure Mastery (EM) - 26 weeks of the series Composition Mastery (CM) - A 52 week series All three series will run concurrently and will dovetail as follows: Q3/26 - MM (Iter 1), EM (Iter 1, Pt 1), CM (Iter 1, Pt1) Q4/26 - MM (Iter 2), EM (Iter 1, Pt 2), CM (Iter 1, Pt2) Q1/27 - MM (Iter 3), EM (Iter 2, Pt 1), CM (Iter 1, Pt3) Q2/27 - MM (Iter 4), EM (Iter 2, Pt 2), CM (Iter 1, Pt4) That's likely confusing, but essentially, MM offered 4 times in that period, EM offered 2 times, and CM offered 1 time. **TO BE CLEAR - THERE IS NO CHARGE FOR THESE CLASSES.** This is an aggressive series, with presentations, homework, group shoots to be added in, likely at LEAST twice a month, image critiques, and an expectation that you are willing to put in the work to elevate your photography significantly. Open to all levels and all equipment levels. Don't let hesitation about your skillset and/or gear keep you from a one-time opportunity. The group will meet every Monday, with periodic exceptions, and we will try to keep as close as possible to the original plan. Obviously, more data to come, and will be published as this is further developed, but now is the time to decide if you want to be a part of this.
