We will be adjusting the itinerary based on the weather conditions and how the day goes. Meeting point: Tournay-Solvaypark Entrance (Boitsfort Train Station) 💶 Contribution: €20 per person, which covers fuel, parking, as well as snacks and drinks along the way. Kindly complete your registration before signing up. Thank you. Yifei Yang BE79 6509 1524 4133 Communication: your name+ event Group size: small and cozy — 7 seats in the van. If you prefer to drive your own car you’re very welcome to join us as well (No need for payment) In this case, please contact the organizers.

Let's meet to write ! Schedule : 11:00 - 11:30 am : Presentation tour. Share briefly with the group about your project and your "goal of the day". 11:30 - 13:30 : Let's write ! 13:30 : Conclusion tour. Did you achieve your goal of the day ? See you soon !

Let's continue the tradition and play UNO, everybody is welcome :) If you're on the waitlist please check your messages, especially on Sunday. If people drop off last minute I tend to message people on the waitlist to see who can come. We'll be playing at the lobby of Radisson RED, Brussels. The address of the hotel is: Rue d'Idalie 35, 1050 Bruxelles My number is 0471 45 55 02. Feel free to call if you cannot solve a physics question, cannot find the place or simply need a hug. I have quickly written a set of rules on how we play. It is assumed that the reader has a basic concept of the game. *** Setup: * Each player starts with 6 or 7 cards each (depending on total number of players) * A card is shown in play in the middle of everyone, this is known as the top card. Goal: * The goal of the game for each player is to get rid of all cards in your hand Rules: * Whenever you go from two cards to one card, you have to say "UNO". * Each player takes his turn one by one, initially going in the clock-wise direction * A card may be played if it matches the same colour or same number or same type as the top card in play * The two black cards (Draw 4 and Wild) can be played regardless of the top card in play. * Interruption rule: You may interrupt the general flow of the game (clockwise or counter-clockwise) if you have the EXACT same card as the top card in play. If you manage to play the card prior to the person whose turn it's supposed to be, then the game continues on from you in the same direction it was previously. (Unless the reverse card was interrupted, then the direction changes). * Draw2 or Draw4 cards can be played in accordance to the interruption rule. The following person after the interrupt has to take the accumulated number of cards. If however, cards have already been drawn AND seen by the person who was supposed to take the cards, then only the remainder of cards has to be drawn. * Once someone has no cards remaining in his hand, play stops and we start counting points. Points: * Number cards have the face value as the number of points. i.e. number 6 is worth 6 points, number 0 is worth 0 points, number 4 is worth 4 points. * Skip, reverse and Draw2 are worth 20 points each * Wild and draw4 are worth 50 points each

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. Price and payments The price of participation is EUR 9. Payment is on-site in cash, or via online. Info provided during or shortly after the event in the WhatsApp group. Cancelations and no-shows Switches and cancellations are free of charge if done more than 50 hours before the start of the matches If you cancel within the 50-hour window before the event starts, you will be placed on the wait-list for the next week's event, whether or not a replacement is found. If no replacement is secured, you'll still need to cover your share of the costs. Contact Questions or first-time approval requests? DM the Organizer with your playing level and availability.

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

This is an open Circle for anyone and open to constellate on any subject. It's a good way to get started if you've been wanting to see what Constellations is all about. We will start with some bodywork exercises and then there will be time for three Constellations on any topic. ​A Constellation is a means for accessing the timeless map you hold within, linking the past to the present and the present to the future. It's a tool to find the origin of the problems we face today such as repeated patterns, blockages, relationship difficulties or health concerns, to name a few, and has the power to reveal hidden dynamics not visible to the normal eye. Then a healing exchange takes place and steps are taken to free you from the past and put you on a road to freedom, understanding and authenticity for your future. ​There are two ways to participate, either as a participant or Space Holder in the Circle or to bring a topic to constellate as an Issue Holder, which is limited to three places. Although one person will bring a subject to constellate, everyone participates. A Constellation is a Healing Circle for all who attend. Price for Space Holders: 50 Euros (12 spots) Price for Issue Holders: 165 Euros (3 spots) ​Date: Sunday, May 10th ​Time: 3:00 to 7:00 pm Location: Shanti Home: Rue Darwin 8, Brussels 1190 (Forest) ​\*There are three spots available for Constellations. Contact me if you'd like to reserve one of these spots. \*Spots are limited for both roles to ensure enough space in the room, although the room is very spacious. *Modified price for students or if you are unemployed. Write me if this is your case.​*Payment must be made beforehand. You can register either to the following account or pay by credit card or PayPal by following the link to the website.

Let's read and discuss non-fiction together. In **April** we will be discussing "Zarifa: A Woman's Battle in a Man's World" by Nobel Peace Prize Winner Zarifa Ghafari. For more information about the book check out goodreads: https://www.goodreads.com/book/show/60383049-zarifa How it works: - 10-15min Introduction round - 1 - 1,5h Free discussion around the book - 10min selection of the next book. (We will vote between three possible books. I bring two suggestions and we select a third one from the group. So if there is a book you like to discuss feel free to put it forward.) Don't worry if you cannot finish it in time. Just join us for a coffee or tea and a good conversation. :) Happy reading!

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.

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.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. 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.
