Decentralized Systems & Applications

Join the UK A Cappella Society for a casual singing session lead by an a cappella expert. This session is aimed specifically at beginners who may not have sung a cappella before, or may not have sung in a group before! We are operating a 'pay what you can' system to make our events accessible to all - we'd suggest a donation of £10 per ticket, but if you're not able to afford that, then you can pay anything from a minimum of £5. (And if you're able to donate more to the charity, then we welcome larger contributions too!) This session will be led by Will Drake, ex-MD of Northern Lights, and currently with professional a cappella groups, Elision & Enchord.

A regular meetup for those committed to practising and improving their Arabic. It is designed for those who know the very basics and want a structured opportunity to practise reading, listening, speaking, and building confidence. If you're still learning the very basics but want some motivation to keep going, you're very welcome to join. Note: This is a practice group facilitated by a native speaker - not a formal teacher or taught class, and not a Quran teaching session. 📚 SESSION FORMAT: ⏱️ 30 mins Intro & Social: We'll go around and introduce ourselves in Arabic. Feel free to prepare 2-3 sentences beforehand if you don't like being put on the spot! 🗣️ 60 mins Structured Practice: A focused session practising together with guidance : ◾ Taking turns reading passages aloud ◾ Listening to excerpts from an audiobook ◾ Working together to translate and understand the text 💬 Continued Socialising: Feel free to stick around afterwards for more informal chat and connection. ✊ Note: Active Muslims is equally about focusing on the actual activity, in this case, it is a practice session requiring mental engagement and active participation (and not just a social), therefore it is advised to approach and attend these events with that mindset, intention and purpose. 📍 LOCATION: Barbican ⌚ MEET: By the cafe G Level (Benugo) ⏱️ TIME: Meet from **11:00am** for intros and socialising. The practice session starts promptly at **11:30am** insha'Allah. 🎒 What to bring: 📚 Any Arabic texts you would like to read 🎧 Headphones (optional, if you prefer listening privately) ➖➖➖➖➖➖➖➖➖➖➖➖ If you can no longer attend, please update your RSVP to free up your spot for someone on the waiting list. ➖➖➖➖➖➖➖➖➖➖➖➖ 🌐 **[@Active.Muslims](https://www.instagram.com/active.muslims)** *(Follow for latest events updates)*

**Meet likeminded UX professionals and discuss ways to use design to reduce burnout.** ​**The Problem:** With stress and burnout on the rise, how can we use design to help Londoners "switch off" and reconnect with nature? ​For our first **design impact lab** session, we’ll be using the Japanese practice of *Shinrin-yoku* (forest bathing) as a lens to discuss how simple interventions can help us reconnect with nature to reduce stress & burnout. ​**The Flow (Sunday 12th April 10:30 AM - 12:30 PM):** * ​**10:00 \| Coffee & Intros \(WatchHouse\, Hanover\):** We’ll meet for coffee to kick things off. You'll meet other attendees and discuss the problem space. * ​**10:30 \| Observation Walk:** A 15-minute mini fieldwork walk to Hyde Park. You'll observe how the environment changes from a busy urban centre to the park and how this impacts how you feel. * ​**11:00 \| Shinrinyoku & Brainstorming:** Once we find a quiet spot, we’ll dive into the world of *Shinrin-yoku*. We’ll discuss how nature can boost wellbeing and brainstorm "micro-interventions" - simple design ideas (digital or physical) that could encourage more people in London to engage with nature to reduce stress & burnout. * ​**12:00 \| Closing & Optional Lunch:** We'll wrap up our discussions and those who have time can go for a casual lunch or picnic in the park. *** ​**Pre-Event Mission:** ​Your mission is to bring **one photo on your phone** of a natural spot that made you feel good recently. It can be a park, a window box, or even a stubborn weed in the pavement. We’ll share these over coffee to explore the different ways in which nature impacts our day to day experiences. *** ​**The Details:** * ​**Meeting Point:** WatchHouse, Hanover (Oxford Circus). * ​**Capacity:** We’re keeping this to a small group to ensure everyone can connect and contribute. Please ensure your RSVP is up to date and let us know if you're unable to attend. * ​**Vibe:** Friendly and relaxed! No laptops, just notebooks and fresh air. *** ​**Why Join?** ​If you’re a designer or researcher who wants to use your skills for more than just "conversion," come say hi. ​It’s a chance to meet like-minded people, learn about forest bathing and brainstorm design solutions to a universal problem. ​It's also our very first event, and I would love to hear everyone's thoughts and feedback to improve. ​**Who is this for?** ​Our events are for UX designers, researchers and other strategic and creative thinkers who are passionate about using their skills for social good, not just profit. ​**Who is the host?** ​Hi! 👋 I'm Max - a London based design researcher. Until recently I was based in Tokyo, where I ran a small design agency and spent over 10 years as a meetup organizer. I'm exploring ways to bring designers together to use our skills to work on meaningful problems. If that sounds like something you're interested in, I'd love to have you join! \*This event is being advertised on multiple sites, so the actual number of attendees will be different to what appears on meetup.

**Welcome to UK Mafia!** We meet regularly near London Bridge. On Sunday we have an intermediate event at **The Kings Arms, 65 Newcomen St, London SE1 1YT** **Do I need to know anything?** This Sunday we are hosting an intermediate event for players who already played before. Please join our group to see our upcoming beginner events as well. **♂️ What is Mafia?** Have you seen 'The Traitors'? Play the game that 'Traitors' is based upon! Mafia is a 10-player social game; it can get competitive, but it's easy to learn. We play at multiple tables. You get a secret role and work with your team to win. A game lasts about 45 minutes, so we play many during the day. The **Mafia team** tries to hide and eliminate the **Citizens**, while the **Citizens** try to find the Mafia through deduction and logic. We also host tournaments and online events with more experienced players from around the world. Ask us about our online games and trips abroad!✈️ *** **[How to Play?](https://bit.ly/HowToPlayMafia)** We will teach you how to play when you arrive. You will quickly see that the game has two phases: **Night:** * The Mafia secretly targets a Citizen * The *Don* (Mafia) learns if a player is the *Sheriff* * The *Sheriff* (Citizen) learns if someone is Mafia ☀️ **Day:** * Each player says in their turn who they think the Mafia are * Then, everyone votes publicly to eliminate one player The game continues until the Mafia are eliminated or they outnumber (or equal) the Citizens. We will explain all the rules at the venue, and you’ll pick it up. Want to learn more about the game? See our wide range of resources, including brochures and videos: **[https://bit.ly/EMF-TIPS](https://bit.ly/EMF-TIPS)** *** \*\* Why Mafia?\*\* Mafia is a global game played by over 15,000 people in 50+ countries, with clubs, tournaments, websites, and federations, like the [English Mafia Federation](https://bit.ly/EML2025) and the [Mafia World Cup](https://www.youtube.com/@MafiaWorldCup/streams). --- **❓Questions -** Message any admin, anytime! --- \- Mafia Tips\, Rules\, Videos\, Resources: **[https://bit.ly/EMF-TIPS](https://bit.ly/EMF-TIPS)** \- Watch games and lessons here: **[https://www.youtube.com/@MafiaWorldCup/streams](https://www.youtube.com/@MafiaWorldCup/streams)** **Contact UK Mafia Club** \- UK Mafia Club Instagram **[https://www.instagram.com/uk_mafia_club/](https://www.instagram.com/uk_mafia_club/)** \- UK Mafia Club YouTube **[www.youtube.com/@UKMafiaClub](http://www.youtube.com/@UKMafiaClub)** \- UK Mafia Club Telegram Channel **[https://t.me/UK_MAFIA_CLUB](https://t.me/UK_MAFIA_CLUB)** \- UK Mafia Club Telegram Chat **[https://t.me/UK_MAFIA_CLUB_CHAT](https://t.me/UK_MAFIA_CLUB_CHAT)** \- UK Mafia Club Discord **[https://discord.gg/fQM7duV96D](https://discord.gg/fQM7duV96D)** \- UK Mafia Club Email **[ukmafiaclub@gmail.com](http://ukmafiaclub@gmail.com/)** \- UK Mafia Club Mafgame profile **[https://mafgame.org/clubs/79/view](https://mafgame.org/clubs/79/view)** **Contact the Mafia World Cup:** \- Mafia World Cup Instagram **[https://www.instagram.com/mafiaworldcup/](https://www.instagram.com/mafiaworldcup/)** \- Mafia World Cup Facebook **[https://www.facebook.com/mafworldcup/](https://www.facebook.com/mafworldcup/)** \- Mafia World Cup Telegram **[https://t.me/Mafia_World_Cup](https://t.me/Mafia_World_Cup)**

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
