Cryptography

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

## (Lesson 2) ## What to expect Project Equilibrium is an in-person introduction to disciplined, rule-based trading automation. This first event is designed to be clear, practical, and approachable no hype, no pressure, and no prior technical background required. ### Why we meet (two-session structure) This meetup is structured as **two lessons**: **Lesson 1 — The “Why” (mindset + framework)** * What Project Equilibrium is (and what it is not) * Why we focus on process, rules, and execution discipline * What “24/7 execution” means in practice * Q&A and open discussion **Lesson 2 — The “How” (step-by-step setup)** * A simple walkthrough of the basic tools you need * Step-by-step guidance to install and prepare the required exchange apps/accounts * A clear checklist to be ready for future sessions (You won’t be left alone—everything is explained calmly and in order.) ### What to bring To make the second lesson smooth, please bring: * **A smartphone** (for authentication and exchange app setup) * **A laptop** (for the setup steps and configuration) If you only have one device, you can still join Lesson 1. The setup lesson is simply easier with both. ### Who this is for * People curious about algorithmic execution and portfolio discipline * Beginners who want a structured approach * Experienced traders who want more consistency and less stress ### Agenda * Welcome + introductions * Lesson focus of the day (Why / How) * Guided walkthrough (where applicable) * Q&A + next steps ### How to find the group * Arrive a few minutes early and look for the **Project Equilibrium** group. * I will be there to welcome attendees if you’re unsure, simply ask the venue staff for the Meetup group name.

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.

Join us for a magical **spring getaway** to one of the most romantic spots near the Belgian border in France- a journey through **majestic ruins**, an **enchanting castle**, and a **storybook village**. We’ll wander through **ancient ruins and a chapel** surrounded by forests, share a **friendly picnic by a lakeside**, and visit the stunning **Château de Pierrefonds** - whose entrance is free on the first Sunday of the month! The day will end with an **apéro among new friends**, the perfect close to the first spring day of the year ### 🌅 **Program Highlights** ☀️ Picnic by a serene lakeside (bring your own lunch) 🏰 Visit of **Château de Pierrefonds** 🏛️ Visit the Louvre Lens museum (The Louvre-Lens is a minimalist, glass-walled satellite of the Paris Louvre near the Belgian border that displays world-class masterpieces chronologically in a single, vast "Gallery of Time.")

Celebrate the arrival of spring with a delicate and inspiring watercolour session dedicated to tulips, the timeless symbol of renewal, hope, and gentle beauty. On the first day of March, when nature begins to awaken, join us to explore the softness, transparency, and fluidity of watercolour through the elegant shapes and vibrant colours of these beloved flowers. During this activity, participants will create light, expressive tulip compositions, focusing on colour blending, brush control, and capturing the freshness of petals and stems. This workshop is suitable for both beginners and those with some experience, offering guidance, creative freedom, and a relaxing atmosphere. Take this moment to slow down, welcome the new season, and express the spirit of spring through art. By the end of the session, you will leave with your own unique tulip painting — a personal celebration of new beginnings. All materials are provided. The activity is free of charge, as sharing is the hope of humanity.

On Sunday, let's pick up again a plan that was sabotaged last autumn by a cancelled train - fingers crossed for more luck this time! We'll explore the southern end of the Parc natural Coeur de Condroz - an area where we don't go too often! We start in the small village of Haversin and follow a combination of GR and local hiking path through forests and fields and meadows, passing a number of castles on the way. The hike ends in Ciney, where we will find a bar for our final drink. As the number of participants is limited, it is important that you manage your registration responsibly: only sign up if you really intend to come and cancel as soon as you know you can’t (this also goes for people on the waiting list!). We will try to keep close to an average speed of about 4.5 km/h. We will walk mainly on unpaved roads. I’ve not tested this track beforehand, so it’s possible that there are some mistakes in the planning (i.e. it may become longer ;-). ●●You can find the gpx track here: **Wikilocs:** https://www.wikiloc.com/hiking-trails/von-haversin-nach-ciney-235163320 **Komoot**: https://www.komoot.com/de-de/tour/2623261338?share_token=aJhHtjvTYFZ0e676GTw3BpS8rZq66Ab3yQvAG9dWmsqPLYBVIW&ref=wtd ●●Meeting point: We meet at 8h35 in the main hall of Schuman train station, in front of the ticket machines and take the train at 8.52 (IC2108 to Marbehan). We change train in Ciney (10.07 L6160 to Marloie) and arrive in Haversin at 10.20. ●● Train tickets: BXL-Haversin 12.60€/7.50€ with train+; Ciney - BXL 11.40€/6.80€ with train+ ●● Back to Brussels: From Ciney there are trains back every hour, at XX.56 plus an additional train every every second (uneven) hour at XX.06. ●● Specifics: Distance: ca 24 km Elevation gain: somewhere between 220 and 310m, depending on App Net walking time: ca 5.5 h Weather forecast: spring!! In the unlikely case of too bad weather, we may cancel a hike, even few hours before the event. If this must happen, we will of course update the Meetup website and send out an email to those registered. So it is important to have access to either the Meetup.com website and/or your emails. ●● What to bring: * Comfortable hiking clothes &shoes * rain gear (just in case) * water and drink for the breaks * Compeed for blisters * some small money for drinks ●● Basic rules: Please RSVP only if you really intend to come. And if your plans change, update your RSVP asap, even hours before the walk. This is basic courtesy towards others. Repeated late cancellations are not well considered (at all). No-shows are even worse. Do not show up for a hike unless you are on the “going” list. ●● Acknowledgement of member responsibility and release of liability: You are responsible for yourself and should be fit enough if you want to take part. As the participation in the events is strictly voluntary and you freely choose to join, it is the responsibility of individuals participating to ensure that they are fit enough and have adequate coverage to protect themselves. By signing up for this event, you agree to release the organisers from any responsibility and liability.

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
