# Digital freedom isn't just for techies. It's for everyone. Join us for a hands-on workshop where you will learn how to adopt Europe-made **and/or** open-source day-to-day applications to gain independence from big tech providers. Concretely: 1. Understand which Europe-made **or** open-source applications exist in the market for *email, calendar, chat, browser, search engine, operating system, etc.* 2. Step-by-step instructions on how to install and configure. You choose which apps you feel comfortable testing! # Agenda 1. Welcome & Introduction (10min) 2. Short documentary on Digital Sovereignty (10min) 3. Hands-on workshop (90min) Together, we can move away from surveillance platforms toward open-source and privacy-friendly alternatives. Europe's digital future depends on choices we make today and it starts with the tools on your phone and computer. ## Inspired by Ghent’s Digital Sovereignty movement Inspired by FOSS workshops that have been thriving in Ghent, this event brings hands-on guidance to help you make the switch, step by step, at your own pace. # What to bring **Preferably**: Laptop. **Optional**: Phone or tablet & USB Stick (8GB) We will work with all types of applications *(email, calendar, chat, browser, search engine, operating system, etc.)* but **you choose** the ones you would like to adopt! # About the organizers This initiative is entirely self-funded, rooted in the belief that understanding our digital world should be open to everyone. ## Carolina Aguilar Carolina is an engineer by training who has spent a career at the intersection of data and artificial intelligence. Deeply committed to European Digital Sovereignty, she hosts this independent workshop to empower others with the knowledge needed to navigate and shape Europe's digital future.

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).

One week before the 20k of Brussels - we do a Brussels Runners Classic (straight from the archives) - 7.5km : past the Flagey ponds, into the abbey, to the bois de la cambre and back. Coffee/Drink at Cafe Belga after the run. The Details Meetup: 09:40 (for a quick briefing) Start Time: 09:45 sharp 📌 Meeting Point: Cafe Belga, Place Flagey 👟 Target Pace: strictly 6:15min/km 🏃 Distance: 7.5 km Effort Level: Conversational. If you can't speak in full sentences, we're going too fast! \# No Bag Drop

Join the Brussels Runners this Sunday to kick off your morning the right way! Whether you are a regular or joining us for the very first time, we can't wait to hit the ground running together. 🏃‍♂️ The Game Plan We will be covering 14-15 km at a steady, comfortable pace of about 6:00 min/km. Expect a scenic, ever-changing backdrop as we navigate a mix of forest trails, dirt paths, and a few road sections. It is the perfect opportunity to enjoy nature, connect with fellow runners, and make some new friends along the way. ☕ Post-Run Rewind Once the kilometers are in the bank, stick around! We will be grabbing an optional post-run coffee to refuel and chat.

Welcome to our weekly event in the upstairs room of The Sister Café, rue Chair et Pain 3, one block from the Grand Place. Please get there early enough to order your drink at the bar first. Thank you! 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. Past questions have been wide and not confined to academic philosophy: What is a genuine friend? Is social media turning us into emotional zombies? Do we lose some of the experience of things by defining them? Are we driven by sex? Is loneliness a personal failure? Is morality relative? **Crucially, be kind and respectful and generous** in your disagreements; remember how much you personally enjoy someone else proving you wrong before celebrating your cutting counterexamples.

What’s up Friends! 👋 If the weather behaves, we’re going for a chill drawing meetup: good vibes, new people, sketching side by side ✨ 📍 Where We meet at Park Cinquantenaire, in front of the "Tour de Tournai" 🏰 (the tiny castle-looking thingy). From there, we’ll pick a spot that feels right - usually somewhere outdoors 🌿 Can’t find us? 🤷🏻 Ping me here. 💡 The Idea Simple: we sit, we draw, we chat. No teacher, no pressure. Just people sketching next to each other and sharing tips if it happens naturally. Bring whatever you like: notebook + pen ✏️ or full watercolor chaos 🎨💦 All styles, all levels welcome. Don't forget to dress for the weather (we’re usually outside) and bring something to sit on - blanket, mat, foldable chair… whatever keeps you comfy. ⏱️ Timing We start at 14:00. Stay as long as you like. Joining later? Drop a message in the chat in case we’ve moved 😊 Once the sketches are done (or we need a break), we might grab a drink if we feel like it. 💸 Price Free. Just show up and draw. 🚦 On the waitlist but really want to join? Or got questions? DM me. 📢 Extra info might drop in the group chat or via DM 💬 Check your messages the day before so you don’t miss anything important 👀 🐈‍⬛ The Friends Code: 👉 Draw what you want, how you want - no judgement 👉 Sharing tips = welcome, not expected 👉 Small groups = chill vibes 👉 Got cool materials? Bring them, flex them 👉 Keep your valuables close — it’s easy to get carried away 👉 Can’t make it? Cancel in time so someone else can join 👉 Don't show up if you are on the waitlist See you there 😉

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
