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!

Hi! Welcome to Thought Experiments in Pubs - Berlin edition, where you get to have deep conversations with people you've never met. The topic will be education. I'll post some questions that will help guide us through the topic as a comment on the day. **Location:** [Atopia Kaffeehaus, Prenzlauer Allee 187, 10405 Berlin](https://maps.app.goo.gl/Ukuup9CTrmedrB6f9) * Please consider that the locations we visit do not charge us for our booking, so in return, please make sure to show your appreciation by buying drinks or snacks. * If you're signed up but can't make the event, please cancel so someone else can take your spot * Make sure you check the right address, there is a sister pub nearby and it's not that one ☝️ **The idea:** A chance to meet and talk at a 'deeper' level, and skip the 'small talk'. **How will it work?** We will have a set of 'Thought Experiments', short, philosophical scenarios and questions, which will be discussed in groups. The conversation will flow freely, there are no strict rules, simply share and discuss your perspectives on the given topic. The thought experiments will be posted here ahead of the event. **Who should come?** Everyone! We believe that the more perspectives, the richer the conversation. This group is not about being experts in philosophy, it is about *doing* philosophy. That is, bringing our various life experiences and lenses on the world to group discussions about the human experience, the nature of reality... etc. **Do I need to bring anything?** No! Just an open, inquisitive mind. We will do 3 rounds of discussions. After the event, I would love to hear your feedback on the session. The thought experiments we will discuss are around the theme of the day. Prompts will be posted here on the day of the event. See you soon! \- Dirk *Thought Experiments in Pubs Berlin is inspired by [Thought Experiments in Pubs London](https://www.meetup.com/thought-experiments-in-pubs/), which originated in 2023 as a social experiment to get people together to connect at a deeper level.

🚀 Workshops: The Human-Digital Synthesis **Kultur\-Technik 2026 \| Women in Big Data Berlin** AI is no longer a future concept—it is already reshaping how we work, create, and make decisions. The real question is: **how do we use it intelligently?** *Kultur-Technik 2026:* *The Human–Digital Synthesis* draws from the European idea that technology is an extension of human culture. In this interactive session, we bring together the Women in Big Data Berlin community to explore how humans and AI will collaborate, build, and evolve together. This is not a passive event— it’s a space to **learn, discuss, and create together.** The event is hosted by **Ojin AixHaus.** Ojin AixHaus is the new, collaborative community space in Berlin Mitte, where scientists, machine learning engineers, founders, creators, and AI enthusiasts come together to build and learn about the future of AI. Ojin AixHaus is free to join, open for startups in residency applications and is currently curating their 2026 events calendar.

In our last sprint, we established our cloud-native foundation by containerizing our agents and deploying them to Google Cloud Run. But manual deployments don't scale and require you to dig out the exact docker build and gcloud push commands from your shell history every time you tweak your agent’s prompt. **The Plan:** This session is about creating a **truly robust, repeatable deployment process**. We will wrap up our infrastructure setup by writing GitHub Actions that automatically build and push our agent containers to Google Cloud Artifact Registry on every commit. With a solid, "set-and-forget" pipeline in place, we'll shift focus back to agent behavior. We will build a simple orchestrator agent that uses the A2A protocol to dynamically delegate tasks to the worker agents living in the cloud. **This is a "Lab" session. We will:** * Automate for Robustness: Replace manual command-line wrangling with a GitHub Action workflow to build and push our Docker images to GCP on every push to main. * Build the Orchestrator: Develop a lightweight central agent designed to interpret a complex user prompt and route sub-tasks appropriately. * Live Multi-Agent Communication: Establish an active dialogue over the A2A protocol between your local orchestrator and your newly deployed cloud workers. **The Format** We run our sessions like an anthology series: Every meetup is a standalone sprint. While we often build on previous results, each session provides a complete experience and remains fully accessible to first-time attendees. This is a high-density micro-meetup limited to 6 seats. **What you'll build** By the end of the session, you'll have: * A Repeatable CI/CD Pipeline: A set-and-forget GitHub Action that handles the Docker build and Artifact Registry push automatically, ensuring consistent deployments without the hassle. * An Orchestrator Agent: A coordinator capable of breaking down requests and utilizing external agent tools. * A Live A2A Network: A functioning multi-agent setup where your orchestrator successfully communicates with and aggregates results from your cloud-hosted workers. **Schedule (Saturday, 10:00 - 13:00 CEST)** * 10:00: Quick round of introductions. * 10:15: Intro session: Robust CI/CD with GitHub Actions, Artifact Registry, and Orchestrator routing patterns. * 10:30: Build time: CI/CD automation & building the Orchestrator. * 12:00: Live demos + technical teardown. * 12:45: Wrap-up + takeaways. **Prerequisites** * Accounts: A Google Account (for GCP) and a GitHub Account (for Actions). * Laptop with dev setup: Docker and Git installed and working. * Access to an LLM API: (Gemini, Claude, OpenAI, etc.). * Mindset: This is a lab for engineers, not a tutorial. We learn by building, breaking, and iterating. **Logistics** * Location: We meet at my office in the Grunewald area near Martin-Luther-Krankenhaus. The exact address will be shared privately with attendees to maintain privacy. Capacity: Limited to 6 seats.

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 engaging panel discussion on **AI Agentic Coding** and how autonomous AI systems are transforming the way software is built. Experts in AI, software engineering, and developer tools will share insights on how agentic AI—systems that can plan, reason, and execute coding tasks—is reshaping modern development workflows. The discussion will cover topics such as AI-assisted development, productivity gains, challenges around reliability and governance, and what the future of software engineering may look like with AI agents as collaborators. Whether you’re a developer, tech leader, or AI enthusiast, this session is a great opportunity to learn, ask questions, and explore how agentic AI is redefining coding

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
