ATTENTION! Because the first Thursday of January falls on January 1, we are moving the Stammtisch back by one week. It will now take place on the second Thursday of the month, January 8. Welcome to the Berliner Bitcoin-Stammtisch, where we gather to talk about the digital currency that's worth more than gold and sometimes causes more drama than a Netflix series. Join our tribe of business beings, developers, and activists who believe that Bitcoin is the future of money, and El Salvador seems to agree! Here you can learn the ropes of Bitcoin, from buying your first fraction to safely storing your private keys. Our current hangout spot is Friedel Richter on Torstraße, because ROOM77 is closed until the last block is mined. You can pay in Bitcoin ₿ or Lightning ⚡ and enjoy awesome regional food with an international twist. So come join the fun, the food, and the revolution! We're waiting for you. 🍔🍔🍔

The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

Data Science Retreat presents 5 Machine Learning prototypes and projects by Batch 44 participants. **Free to Attend!** Hey Berlin Data Folks! We’re kicking off 2026 with our first data event of the year. Join us for project demos, fresh ideas, great conversations, and of course—pizza & drinks on us 🍕🍻 Don’t miss it! **Agenda:** **17:30** \- Drinks and Networking **18:00** \- Welcome & Introduction Followed by Project Presentations **Project Ideas:** **1\. AI/ML \- EV Battery Shape Classification** ***Project by Uma Maheswari Obbani*** The project aims to automate the detection and classification of used electric vehicle (EV) batteries by shape — cylindrical, prismatic, or pouch — using AI/ML and computer vision techniques. The goal is to provide manufacturers and recyclers with real-time insights about battery type distribution, enabling efficient sorting, inventory management, and safety compliance. **2\. Developing Scalable and Reliable Coffee Yield Forecasting Tools** ***Project by Dr. Juan Fernando Duenas Serrano*** The aim of the project is short term coffee yield forecasting improves planning and value creation across the supply chain, from farmers to roasters. Current yield estimation methods are not scalable and require specialized expertise. This project explores computer vision as a scalable alternative using smartphone images. A YOLOv8 object detection model counts unripe Arabica coffee cherries on branches. The model can estimate yield at tree or farm level with optional user input. A Gradio or Streamlit web app will demonstrate, evaluate, and extend the model’s potential. **3\. Classic Car Diagnostic Tool** ***Project by Lulezim Ukaj*** This project aims to develop a specialized AI-powered diagnostic tool for classic cars that leverages community knowledge from German automotive forums. Unlike modern OBD-II–based diagnostic tools, which dominate the market, this solution targets pre-1996 vehicles where standardized electronic diagnostics do not exist. **4\. Enhancing on\-site audience audio** ***Project by Thede Witschel*** This project develops an enterprise-grade AI platform that automates the extraction of ESG data, regulatory compliance checks, and peer benchmarking for companies. Utilizing NLP and machine learning, the system converts unstructured sustainability reports into standardized metrics, facilitating real-time compliance monitoring and competitive intelligence across various industries. Business Impact: Targets the rapidly growing ESG software market, serving investment firms, consulting companies, and institutional investors requiring automated analysis for portfolio decisions and regulatory compliance. **5\. Ludus Automated Game Balancing: An AI\-Driven Evolutionary Pipeline for Card Game Meta\-Stability** ***Project by Rami Aldrea*** This project addresses the critical and often labor-intensive challenge of balancing a complex digital card game meta, specifically focusing on a 70-card set. The primary objective was to develop and validate an automated, iterative pipeline capable of achieving and maintaining a stable, competitive game environment where no single card or archetype consistently dominates. The desired outcome was a game meta with a mean card win rate of 50%, minimal variance (ideally <5% standard deviation for competitive e-sports), and preserved strategic diversity, all while significantly reducing manual design time. **20:00** \- Open for networking **20:30** \- Wrap up We have limited seat so please RSVP soon. See you all at the event.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA

Happy New Year Colleagues, The next Columbus Futurists public forum will be **Thursday January 15 at 12:00 pm noon** (eastern) [https://osu.zoom.us/j/93451873651?pwd=RXIyZ2t5RjRqRG02UGQ1aEFVQ1NFZz09](https://osu.zoom.us/j/93451873651?pwd=RXIyZ2t5RjRqRG02UGQ1aEFVQ1NFZz09) Please come prepared to offer your **"What if?" questions for 2026**. (I will offer seven to begin our conversation.) I also would like to announce the publication of my latest book: *[Anticipatory Biographies: Personal Histories of the Future](https://link.springer.com/book/10.1007/978-3-032-08912-0)*, the tenth volume in the “Anticipation Science” series. Grounded in design fiction, futures research, anticipation science, and scenario writing, *Anticipatory Biographies* envisions how the world will be reshaped by artificial intelligence, technological automation, climate change, political disintegration, and the decline of higher education. This work of creative non-fiction bridges literary and scholarly forms, blending biography and design fiction with research-based insights to offer a narrative-based method for exploring futures. Ed Finn, Director of the Center for Science and the Imagination at Arizona State University says: “In this book **David Staley has invented a delightful new genre: the future biography.** He invites us to step into gritty, thrilling, and inspiring futures elbow-to-elbow with the characters living those stories. *Anticipatory Biographies* beautifully synthesizes Staley’s training as a historian, his expertise as a futurist, and his desire to ignite the imagination of his readers.” Hope you'll be able to read it, and hope to see you all on the 15th.

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries.
