**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).

We are back in the c-base! Do you already run NixOS and want to talk to other people or want an introductory session with some NixOS users. Just bring your machine! Usually there are no topics, we just sit in front of our computers, talk about stuff, debug some problems or review some PRs on nixpkgs. There are drinks usually available from the c-base bar. If you can't find us. just ask around or ask in irc (#krebs on hackint)

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!

Liebe JUG-Mitglieder, wir möchten Euch herzlich zu unserem nächsten Stammtisch, der jeden ersten Dienstag im Monat stattfindet, einladen. Alles weitere kann im unserem Blog unter http://www.jug-berlin-brandenburg.de/ gefunden werden. Viele Grüße Sandra, Jan, Jörg und Oliver

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.**

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.

Thank you. 😊 Patty Cake offers everything from cupcakes, cookies, cakes, muffins, whoopie pies, as well as gluten free goodies. They also have coffee, oat milk and cold brew

Sleep in on Sundays. When you've had your fill of pajama-time, roll out and have some tasty brunch with your fellow Humanists!

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. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon
