Extreme Programming

Come and join **your fellow peers** to have a good time **practicing** **writing code** to get better at writing code in your real jobs. We’ll start off with **koffiekoeken** and form pairs to do the Game of Life Code Kata. After 45 minutes we’ll delete all our code and talk about new insights you’ve gained. Then we’ll pair up with new people and do it all over again but with new constraints applied, like not using conditional expressions, or committing code on green within 2 minutes. At some point we’ll break for lunch and we’ll figure something out for dinner too. ## **What to bring?** This event is very hands-on and it’s always better to come prepared. Bring your laptop (and peripherals if this helps you code better). Make sure you’ve installed GIT, and some programming languages you like. Here are some kickstarting code repositories you can already clone to see if they are usable for you on your machine: [https://github.com/SoftwareSandbox/coderetreat-kotlin](https://github.com/SoftwareSandbox/coderetreat-kotlin) [https://github.com/SoftwareSandbox/coderetreat-java17](https://github.com/SoftwareSandbox/coderetreat-java17) [https://github.com/SoftwareSandbox/coderetreat-elm](https://github.com/SoftwareSandbox/coderetreat-elm) [https://github.com/TimmyGilissen/coderetreat-dotnetcore](https://github.com/TimmyGilissen/coderetreat-dotnetcore) ## **Schedule** 08:30 Welcome with koffiekoeken 09:00 Kick-off, facilitated by Vincent Verhoeven and Tim Schraepen 09:30 First kata 12:30 Lunch break 13:30 More kata’s 17:30 Closing ## **Is this event for me?** If one or more of these apply to you, I’d say you’ll have a good time and learn something new: * You’re a student and want to learn from people that code for a living * You want to improve your coding skills * You want to learn how to improve your AI context/harness engineering via software crafting skills * You’ve never done Test Driven Development before * You’re experienced and want to pair with somebody outside of your team * You’re very experienced and want to help your peers grow their coding skills ## **Practical Info** Our host of the day is Unlockd and along with sponsoring the food and drinks, they’ve lent their office space (desks, monitors, meeting rooms, …) to help you become a better software developer. Unlockd is an agency specialised in building (mobile) apps for any screen. They focus on collaboration with clients who appreciate creating value through small iterations. They do this for mobile, web, desktop and embedded devices. In small teams they focus on app development but include all involved 'edges' like back-end/middle layers, embedded/BLE interfaces, design, dev ops, app store publishing and optimisation, production monitoring, etc. They've build apps for Hubo, Standaard Uitgeverij (Strips), Lava (fruite & vegetable auctions), Classified Cycling and many more.

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😉

We are living in an age of ever increasing intelligence and power. Individual humans haven’t really become any smarter or more powerful, but together we’ve developed systems that increase the control we exert over our environment. If we look at a country like China for example, the last 50 years have seen an undeniable and unprecedented increase in living standards, which correlates with [an increase in happiness and life satisfaction](https://ourworldindata.org/happiness-and-life-satisfaction). Another way to look at this is that we’re constantly finding ways to overcome the limitations imposed on us by life/existence/the universe. Hungry? Just go to the supermarket! Had a bad fall? Here is surgery and some painkillers! Cold? Open your tap and warm water flows out like magic! What if we follow this process to its conclusion? What does a world without struggle, problems or limitations look like? What would the absence of limitations do to our behavior, our values and our ethics? Would we still be human or does something get lost along the way? Is our current intelligence explosion missing a balancing wisdom explosion? We’ll be approaching these topics by thinking creatively about the following concrete questions among others: \- If we had a vaccine against lung cancer\, why shouldn’t we smoke? \- If we could suck all of the CO2 out of the air\, why shouldn’t we continue using fossil fuels? \- If antidepressants had no side effects\, why shouldn’t we all take them to deal with grief? \- If we could breed animals \(human or nonhuman\) without pain receptors\, why shouldn’t we eat them? \- If all human activity could be automated\, why shouldn’t we become “WALL\-E people”?

This meetup is a beginner-friendly session introducing version control for Unity projects, with a look at three common tools: Git, Perforce, and Unity Version Control. The goal is to help you understand what version control is, why it matters for Unity development, and what options are out there. The format will likely be presentation-style, with live demos and time for questions throughout. You'll see each tool in action and learn how they fit into a Unity workflow. What to Expect: * An introduction to version control and why it's essential for Unity projects * An overview of Git, Perforce, and Unity Version Control * Demos of each tool in a Unity workflow * Tips for getting started * No prior version control experience required * Resources for continued learning All experience levels are welcome. Whether you're new to version control or already using one of these tools, this session will help you understand what each one offers. Food and drinks provided. Join us to learn more about version control options for Unity.
