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. He holds an engineering degree from University of Mons Faculty of Engineering and a Master's degree in Artificial Intelligence. In his current role, Olivier focuses on designing, operating, and evolving enterprise data platforms based on technologies such as Apache Kafka, Elastic Stack, and Cloudera. His work spans data ingestion, real-time processing, monitoring, observability, and platform engineering in a large-scale railway environment. **Safia Souabi** is a Data Engineer with 6 years of experience at Infrabel in Brussels. With a BSc and MSc in Physics from London, she combines a strong analytical background with expertise in building and operating large-scale data platforms for mission-critical operational and asset data. Experienced with Apache Kafka, Elastic Stack, and the Cloudera ecosystem (Hadoop, Spark, Hive/Impala), she delivers scalable batch/real-time data pipelines and optimized ETL/ELT workflows. She works closely with stakeholders to translate requirements into reliable data products, with a strong focus on data quality, governance, security, performance, and platform resilience.

That's all folks **Unlocking the Power of Spec-Driven API Development in the Age of AI** *by* *Tim Haselaars* AI ships API code fast. Without a spec, it's chaos. This talk covers Spec-Driven API Development — using a single OpenAPI spec to automatically generate docs, tests, mocks, and SDKs. It explores how AI can assist: drafting specs from conversations, catching vibe-coding pitfalls early, and converting your spec into an MCP server so AI agents can call your API without any custom integration *Tim Haselaars has a track record in Technical Product Management with a passion for music and APIs. He contributes to API-related open-source projects such as Inspectr, Portman, Postman-to-K6, and OpenAPI-format.* **Growing Disks and Fighting DDoS with (Franken)PHP** *by Siebe Vanden Eynden* At team.blue we manage a large number of servers, and keeping them happy isn’t strictly our job as developers. However, we’re happy to help! Working alongside our operations team, we use PHP to grow disks, combat DDoS attacks, scan for malware, and much more. This talk delves into our internal tools, our collaboration with the operations team, and the process of building and distributing those tools. (Spoiler alert: FrankenPHP!) *Siebe Vanden Eynden is a full-stack developer at team.blue, with PHP and TypeScript as his primary tools. He sees the value in automating boring tasks so that more time can be spent on the fun ones.* -- If you'd like to host or speak at one of the meetups, make sure to contact us at [hello@phpantwerp.be.](http://hello@phpantwerp.be./) -- **Our meetups are sponsored by Take The Lead** **Take The Lead** is a Belgian e-commerce agency that helps companies launch, optimize, and scale their online business.

**Welcome to The Club.** A **curated** social community in Brussels for people who want real connections, memorable experiences, and **better energy than the usual random meetup chaos**. Most of our events happen in **private homes**, gardens, hidden places around Brussels, or unusual locations outside the city. The goal is simple: create the kind of atmosphere where people actually talk, laugh, connect, and want to come back. We organize things like: • gourmet lunches & dinners • picnics & roadtrips • cooking nights • walks around Brussels • karaoke & movie nights • debates & discussions • card and social games • occasional “chaperoned” social evenings where people can meet naturally in a safe environment The difference is that we personally curate and vet new members. The host actively introduces newcomers, helps people integrate into the group, and keeps the atmosphere respectful and relaxed. We have zero tolerance for creepy behavior, unwanted pressure, spam, random uninvited people, or drama. *Unfortunately, posting too many details publicly on Meetup or on the internet in general quickly attracts bots, scammers, fake profiles, crypto weirdos, and people who completely ruin the vibe for everyone else.* That’s why most of our real coordination happens privately through our ***vetted WhatsApp community***. To join, simply scan the QR code in the image. If you are on your phone and cannot scan it directly: • take a screenshot of the image • open the screenshot in your photo gallery • most phones can automatically detect QR codes from photos by long pressing or using Google Lens / iPhone scan feature Then request access to the group and introduce yourself briefly. See you soon

Feel free to join us to play any games !

This workshop series is a **follow-up to the ESP32 Robotics workshop**, but with a different concept.

How do we connect to people? What is so great about being different? Is love selfless? Should we be dreamers or realists? What values are we losing? When are we at our best? Does childhood ever end? Is morality a matter of convenience? What makes a person beautiful? Such questions, and many more, await you Sunday at Sister's Cafe (second floor) . After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations :-).

Let's get together and listen to **[Eric Rico](https://www.linkedin.com/in/ericrico/)** from Unity3D (**From Joints to Gestures: Reading Hands in Unity**). A hand tracker gives you joints, not a gesture. This talk shows how you get from raw joints to a "thumbs-up" in Unity: the pipeline that cleans up the data, how a gesture becomes a few 0-to-1 values within tolerance, and why orientation matters as much as finger shape. Includes a live demo of tuning gesture thresholds. Eric also runs the **[Columbus Unity User Group](https://www.meetup.com/columbus-unity-user-group/)**. Check it out! ***Bring your laptop and expect to write some (non-AI-generated) code!*** Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

**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** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. 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

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!
