Slow Dating for Book Lovers 📖✨ Friday, April 10 · 7 PM · Metis Books & Café A slow dating night for MSM (men who have sex with men) who love books. Gay, bi, queer, trans — if you're a man who's into men and into reading, this is your night. How it works: you arrive, choose a literary pseudonym (an author, a book title…), and the evening unfolds — group icebreakers, one-on-one conversations, pauses to grab a drink or a bite at the café, and plenty of room to just be yourself. No rush. No pressure. Just good conversations, good books, and maybe a good connection.

Please bring clean indoor shoes with you to the location <3 The event fee varies between 5 to 10 Euros.

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.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? 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
