Decentralized Systems & Applications

# 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.

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 !

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.

Can’t find us? 🤷‍♀️ Just ping me here. 💡 The Idea Chill picnic: bring your own drinks 🧃, snacks 🥪🍓, blanket, and games 🎲🏸 (sharing always appreciated 😋). We’ll break into small groups depending on the vibe: games, chats, sports. ⏱️ Timing We kick off at 14:00. Stay as long as you like. Joining later?

Just 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 critical 🙄. 🐈‍⬛ The Friends Code: 👉 Games we play = group decision 👉 Smaller groups = cozier vibes 👉 Got a favorite game? Suggest it or show up with it 👉 Can't make it? Cancel on time so someone on the waitlist can grab your spot 👉 If you’re on the waitlist, showing up is at your own risk 😄 See you there, folks 😉

Join us for some friendly Badminton games- all levels welcome! IMPORTANT- in order to secure your place you’ll need to both book a spot on Meetup AND pay €8 by Friday morning. This is to make sure we can cancel courts if demand isn’t there, and make sure we’re being fair to people on the waitlist. Refunds will only be possible after Friday AM if another player is definitely able to take your spot Always worth joining our W’app group as well for faster, often better, updates! https://chat.whatsapp.com/IL7Gbs6TmIm0GXyidQxCFS?mode=gi_t

First time comers Please make sure to read the rules and contact the organizer before! Otherwise you will be moved to waiting list. Apologies for inconvenience but we have to do it to avoid no-shows. New and Interested in being part of our group? Join here, https://chat.whatsapp.com/KqdVhyuBhFz1d56lv4WVVi Please Direct Message the Organizer with your level. Approval is required before your first RSVP. Games format. 95% are double games (unless someone needs a break), typically 4 people play together 2 sets and then mix with players from other fields. We play with plastic shuttles - Yonex Mavis 2000 (which are provided). Registration If it's your first time, please send a private message to the host to confirm. No-shows are taken quite seriously because they unbalance the games a lot. Also once you register please keep an eye on you private messages, in case we need to contact you. Players level Having players with much less experience often unbalances the game making it much less interesting for more experienced players. We still try to be welcoming. As a rule of thumb, if you know what a "clear" is, you are welcome to join. Otherwise, feel free to get in touch with me (John) and we can see if we can arrange so you and existing players can have good experience playing.

Hello! This is a meet-up to play tennis from 2 pm to 4 pm on Sunday. Meeting is on the courts. The courts are booked under the name Jean-Marc. This event is for intermediate and advanced players and not organised for novice players or beginners. Please make sure to bring the exact sum of 10 € in cash. The event is non-commercial. This sum covers the cost of the courts reserved. The organizer is not there to make money out of you. Ladies are encouraged to join. If anyone wants to drop out, they should do it on Saturday morning, not on Sunday the day of the meetup, another wise it would be too late to find a replacement in time or to cancel a court in time with reimbursement. If you don't do this, you will be asked by the organizer to reimburse your participation fee. If this happens too late then those who have cancelled after Saturday morning will have to cover the extra cost for reserving the courts. In the past meetups, it happened too many times that we were an oneven number and because of that all those present had less fun to play. If you don't show up without giving a written excuse in time, the first future participation will be cancelled and you will be asked to reimburse the participation fee. If it happens too many times you will not be able to participate anymore. In case if we are an uneven number of players, then the last player (except the host of course who has to collect the money) can leave or persuade other players to play with him or her. Of course if the last player leaves, then he or she doesn't have to pay the participation fee. If this player leaves, he or she will be added on a future event by the host or organizer in the participation list if the player is far away in the waiting list. This is the advantage of leaving on a voluntary basis;-). We operate on the principle of Fair Play as we do not have umpires or referees. Any disputes or disagreements over line calls or scores should be resolved immediately on the court and, when agreement is not possible, the point or game should be replayed. To be able to replay the game, 3 players need to agree on that without manipulation of the one who disputes an entire game, anotherwise injustice could occur where in the end possibly the biggest cheater could win... This situation applies also, if the host or the organizer is involved. When one of the players still doesn't accept this compromise, then it should be reported (meetup message by preference) to the organizer or host of the meetup event. One of the consequences could be that the first upcoming event could be cancelled by the organizer for the player who doesn't comply with the compromise to play the point or the game again. If the same player does that again for a second time, then the person will see 4 of his next tennis meetups cancelled. If this happens a third time with the same player, then the player in question will be banned from all future tennis meetups with an exclusion as a final result. Whenever there is a big problem, it should be reported as well to the organizer of the group so he can, if necessary, take actions to improve the situation for all the players. Please also note that if you are the first on the waiting list, you will automatically be moved up to the attendance list if someone pulls out. So if you are on the waiting list and see that you cannot attend, please also change your status to not going. If you would like to organize a meet up either this week or next week please get in touch with me, my name is Jean-Marc. It will depend on your initiatives to create more tennis meetups per week.

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
