Cryptography

How are the dynamics of freedom, safety, risk and reward all interrelated? Is it simply a question of how we can always maximize both freedom and reward? What roles do risk and safety/security play in this system? Can freedom and security be considered simply both as rewards, each with its own values and merits? Are freedom and safety (not) nevertheless zero-sum related, more of one entailing less of the other? How are freedom and risk-taking related? Does risk-taking (not) by definition always mean less security? The concept of risk can mean: 1)the probability of something bad occurring ("frequency") and/or 2)how bad that bad thing can be ("amplitude") What implications do each of these two different types of risk carry regarding both freedom and security? How are freedom, risk and recklessness interrelated? What does the concept "freedom to make the best choices" mean? Is individual freedom at the expense of safety (not) over-prioritized in our current world culture (possibly in some regional cultures more than in others)? Or, seemingly contrarily, is our culture/society in fact overly-obsessed about safety? Is it true (or not) that risk-taking always leads to greater potential reward? Is risk-taking nowadays - possibly as a result of (and/or to promote) capitalist culture? - (not) _ethically_ overvalued? Are some regional cultures in today's world more reward-driven (for example, to become rich, glamorous, famous and powerful) than others? What should be our ideal culture/attitudes regarding rewards and the earning of rewards? What values should we give to freedom, risk, reward and safety in a _war_ situation? In our society/world, should there be _fewer_ or _more_ rules with regards to risk-taking, security and reward?

What's up Friends! 👋 
Ready for some bouldering fun? Boulder-what? 🤔 It’s climbing (FR: escalade, le bloc) up to 4.5m high without ropes—and in my case, without much hope! 😂✨ It’s a super fun indoor activity, but be warned: it does require a certain level of physical fitness and/or skill. Most importantly, though, it requires awesome company—which we’ve got! 😎
 The Idea: 📍 Meeting Point: For those arriving at 14:00, we’ll meet at the cafeteria (next to the billiards table). Feel free to start earlier or later—just drop me a message or write in the group chat so we can meet up. 💪 Stay & climb as long as you want - venue closes at midnight! 🥤 Recharge: If you’ve had enough climbing for the day (we usually do this after 2 hours of climbing), we may head back to the cafeteria (or to the rooftop if it's sunny🌤️) for snacks, drinks & games. Cafeteria closes at 22:00. Where: 📍Arkose: (Brussels Canal) Rue Willy de Bruyn Straat 52, 1000 Bruxelles, Belgique 🔗 https://arkose.com/

Fees: 🤑Entry fee without shoes: - 18 eur (first-timers 10€ with online promo activated) - reduced rates: students, minors, job seekers, firefighters, military (proof required) 👟 Shoe Rental: 5€ (if you don’t have your own) 🎫 10-session pass: 150€
 Good to Know: ✍️ First-timers need to create an account (takes 5min) - do it in advance and pay online to pay less and avoid wasting time onsite 💦 Hydration is key! Bring a water bottle. 🔐 Lockers available, but bring your own padlock. 🚿 Changing rooms & showers on-site. 👕 Wear comfy sports clothes—it gets intense! 🧴 Only liquid magnesium is allowed (for grip) - in reality most people use powder🤫 👟 Thinking of going regularly? Bouldering shoes are a great investment! (Decathlon: ~45-65€ per pair.)

⚠️ Safety First! Bouldering is fun, but safety comes first! Stay alert, know your limits, and don’t take unnecessary risks. Enjoy responsibly! 💪 
📢 Further details may be shared via the group chat or via DM 💬. Make sure to check your messages 👀 at least on the day before the event to avoid missing critical 🙄 announcements. 🐈‍⬛ The Friends Code:
👉Respect and positive vibes, if not 💥🥊
👉Can’t make it? Cancel or drop a message in the chat - helps running things smoothly! 👉 Don't show up if you are on the waiting list or show up at your own risk. 
See you at the walls folks😉

[This is a paid workshop and sign-up via the website is obligatory.](https://www.wordcraft-collective.eu/courses/the-poem-of-the-book) Do you have a favourite book you want to make the subject of a poem? This workshop will explore poems that are in dialogue with literature, and how poets bring in their favourite authors. From the classics to the contemporary, we'll look at how poets explore their relationship with the novel and their authors. Homage, dialogue or exploration, we'll see how prose becomes the subject of poetry and discuss the significance of particular novels for you. We'll use poems as prompts, poems that look at Woolf, Keats, Gide, Tolstoy, Cavafy, to see how poets and those closest to them have engaged with their literary heroes through poems. Please have a think in advance about the books and novels that have been important to you or to those around you, perhaps the characters in the novels you related to or reacted to, or your relationship with the novelists themselves. 📅Date and time: Saturday 28 March 11:00 to 13:00 📍Venue: Pianofabriek, Rue du Fort 35, 1060 Saint-Gilles 💰Price: €25 Eur (non-member) €20 Eur (Member).

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

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.

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 !

Something special this week- our first ever tournament week! To understand the rules, and to participate, please join our w’app group below

So this month's prompt is more general. I think we can all agree that we are living in "unique" times that require coping skills. I think that one role and/or purpose of philosophy is to help us deal with our daily lives and our "unique" times. So, let's share our feelings and thoughts about which philosopher/philosophy we turn to in order to deal with our crazy events. Who/what helps you stay focused in your daily life and helps you sleep at night. I find that Stoicism with a little philosophical pessimism mixed in goes a long way in helping me deal with what I see as very destructive, fearful and mean spirited public policies at both the state and federal levels. Hope to see you on March 28th!

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. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
