Welcome to Terrible Football Berlin!
Do you want to play football but don't want to pay? Are you a bit unfit, a bit old, or a bit Terrible? Want to have a relaxed kick about and a couple of beers after? Then Terrible Football is for you!
Anyone can play: any ability, any age, and any gender. Terrible Football is about miss kicked clearances, sweet half volleys and desperate diving saves. We play in the rain, sun or snow. It's completely free, and always will be. It's open, inclusive and Terrible.
We usually play on Astro (artificial grass) and sometimes on grass, depending on numbers. Bibs, balls, and cones are taken care of! Just bring sporty clothes and a pair of rubber studded football shoes you'll be good to go! You don't need shin pads and we don't allow hard plastic or metal studs.
The exact location of the event is in the Telegram group description (https://t.me/joinchat/OkWQBBcw3b7ptauwrIEfig Still trouble finding us? Send a message in our Telegram group and we'll help you out. You'll also stay up to date with last-minute changes!

Back in August, we explored how Design Thinking can help us uncover and validate the right problems. But even when we agree on what to build, things often go wrong, not because of bad solutions, but because we don’t fully understand what the problem actually means in practice. In this session, we’ll build on that idea and focus on the next step: turning vague ideas into something concrete, shared, and testable. Using Example Mapping - a lightweight technique from Behaviour-Driven Development (BDD) - we’ll work in small groups to: * Break down a feature into rules, examples, and questions * Surface hidden assumptions and edge cases * Align on what the behaviour of a system should actually look like If the previous session was about finding the right problem, this one is about understanding it well enough to build it right. This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there!

**Coût de l’événement : € 0,50** On se rencontre mardi prochain pour discuter en français dans une ambiance amicale chez le café / resto Spreegold en Prenzlauer Berg, ou on a réservé une table (il faut demander du French Meetup). Le restaurant n'accepte pas les paiements en espèces. Merci et à bientôt! PS: Le coût de **€ 0,50** s'explique par le fait que par le passé, certains participants ont oublié de payer leurs consommations, laissant l'addition aux autres.

**BitDevs Bitcoin Socratic Seminar Berlin @ c-base Raumstation** Join us for our monthly interactive **[Bitcoin Socratic Seminar](https://bitdevs.berlin)** in Berlin! We’ll start with pizza and beer (sponsored by [Ordimint.com](https://ordimint.com)), followed by deep-dive discussions on the most interesting *technical* developments in Bitcoin from the past month. Participation by everyone is highly encouraged! Our goal is to foster lively discussion, knowledge sharing, and debate. In the weeks leading up to the event, participants gather topics such as: * New research papers * New BIPs and BOLTs * Network statistics * Technical blog posts * Mailing list and Delving Bitcoin threads * Pull requests and updates from key repos (Bitcoin Core, LND, Core Lightning, Eclair, BDK, rust-bitcoin, LDK, Electrum, …) Each topic is briefly introduced by our moderators and then discussed before moving on. The full list of links will be published at [bitdevs.berlin](https://bitdevs.berlin) 1–2 days before the event — please review them in advance to get the most out of the discussion. **Important details:** * This event is highly technical — best suited for those with a solid grasp of Bitcoin internals. Curious newcomers are always very welcome, but expect in-depth conversations (see the former topics at [bitdevs.berlin](https://bitdevs.berlin)). * Chatham House Rule applies: you may share what was discussed, but not who said it. No livestream, no photos, no recordings. * The evening begins with food and networking; people often stay after the seminar to keep talking. **Co-hosted by:** * [Felix](https://x.com/FelixWeis) * [Freerk](https://x.com/freerko) * [Fabian](https://x.com/fjahr) For background on the idea of BitDevs Socratic Seminars, see [this article](https://bitcoinmagazine.com/articles/op-ed-want-to-learn-about-bitcoin-try-a-local-socratic-seminar).

Join us for an open and collaborative meetup dedicated to OpenClaw and Nvidia Nemoclaw — the emerging ecosystem for AI‑driven automation and intelligent agent workflows. Whether you're already working with Claw agents, experimenting with the tooling, integrating automations into real systems, or just curious about what’s possible, this meetup is the place to connect. **What this meetup is about** A relaxed, open discussion space for topics such as: * Building and orchestrating Claw agents. * Best practices for running and scaling ClawdBot Integrations, workflows, and experimental setups. * Secure agent execution and sandboxing. * Tools, extensions, and community‑built add‑ons. * Troubleshooting, insights, and real‑world use cases. * Ideas about the future direction of the OpenClaw ecosystem. This is a topic‑open session — everyone is welcome to bring questions, demos, ideas, or challenges they’re working on. No slides or formal agenda required. Bring snacks or drinks if you like — completely optional. We’re excited to meet developers, tinkerers, researchers, and enthusiasts who want to explore the next generation of agent‑based AI automation together.

If you are navigating life with both being a person of color and being neurodivergent—this sharing circle is for you. **Details** 📅 Wednesday, 8th of April 2026 🕕 18:30 - 20:30 📍 Meeting Room in BIW\*oC Rising https://maps.app.goo.gl/Y6wTvMXV4rCUkgzP8 🎟️ Free but a donation for the space is highly appreciated. **Community disclaimer:** This circle is organized entirely by neurodivergent volunteers who contribute their time, energy, and resources to create this space. They deserve patience and kindness. **What happens here** * We gather. We share. We listen. * Stimming, fidgeting, moving around, stepping out for a break, is always welcome. * For this first event, we will try to open with a round of introductions. If you feel called to, you can share three words that represent your neurodivergent and BIPOC life. * There is no pressure to share if you can't think of any or would rather just pass. * After we hear the words, we can see what themes emerge and let the conversation flow from there. * The format of this event can be changed and discussed the further we go with this sharing circle. **This space is for you if:** * You're a person of color—Black, Indigenous, Latinx, Asian, Pacific Islander, Middle Eastern, mixed-race, or any marginalized racial or ethnic identity. * You're neurodivergent—diagnosed, self-identified, questioning, or just know your brain works differently: ADHD, autistic, dyslexic, AuDHD, or any other neurotype. **Community Agreements** * **This is a space to heal, not to harm.** Experiencing racism is painful and real. That pain is welcome here. However, this is not a space to express sexist, misogynistic, homophobic, transphobic, ableist, colorist, or any other discriminatory attitudes toward any person or group—regardless of their identity. We all carry wounds. But those wounds do not give us permission to wound others. * **Confidentiality:** What is shared in the circle stays in the circle. This helps us build trust. * **No Fixing:** This is a space for sharing experiences, not for giving unsolicited advice, diagnosing others, or trying to "fix" someone. We are here to witness and support, not to problem-solve. * **Content Warnings:** If you plan to share something that involves heavy topics like trauma, self-harm, or graphic discrimination, please give a brief warning before you start (e.g., "I'd like to share something about a difficult experience..."). This allows others to gently step out or prepare themselves. * **Respect the Space:** Please be mindful and respectful of the venue that hosts us. **About the Space Hosting Us** "BIWOC\* Rising is a Berlin-based intersectional organization for Black, Indigenous, and Women\* of Color, as well as trans, intersex, and non-binary people of color. It provides a safer workspace, socal club, networking opportunities, and its current project, EquiNet, which offers workshops and events to support members’ social, professional, and economic empowerment. The organization aims to build community, challenge systemic discrimination, and strengthen opportunities for marginalized groups through inclusive spaces." **Learn more about BIWOC\* Rising**: https://biwoc-rising.org/ **We can't wait to share space with you.**

Main Library, Meeting Room 3B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

We meet at lunch each week and each meeting follows a fairly organized agenda. First all participants pass their business cards around. Then each member and guest is invited to give a one-minute overview of their company and what is a perfect referral for the week. We always have a 10 minute presentation from one of the members about their business in more detail. And finally we pass referrals. You're welcome to visit. Nobody is ever put on the spot. Bring plenty of cards!
