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)

Dear Community, Another month with two great talks in the agenda. This time we are meeting at our home **NLND Berlin**, with one talk covering AWS AgentCore while the second one about Redshift Data sharing. =================================================== 18:30 - Warming up and networking chat 18:45 - Intro by AWS UG Berlin & NLND 19:00 - 19:40 - **Gamei Chin & Milad Rezaeighale // The Diabetes Sweet Spot: Using AWS AgentCore to Empower Data-driven Lifestyle Decisions** This session is about building production-ready agentic workflows with Amazon Bedrock AgentCore—from running agents securely at scale on a managed Runtime, to exposing and orchestrating tools via AgentCore Gateway (including MCP-based tooling), adding different types of memory for context and personalization, and enforcing security and governance with Identity and Policy for controlled tool access. It ends with a live demo of a practical use case: an agentic app for glucose monitoring, showing the end-to-end workflow and monitoring in action. 19:40 - 20:00 - Networking break with food, snacks and drinks 20:00 - 20:40 - **Jirka Hubacek // Breaking Down Monolithic Redshift Using Data Shares** As data platforms scale, managing competing workloads in Amazon Redshift becomes increasingly challenging. Traditional WLM (Workload Management) often isn’t enough to effectively prioritize traffic — you end up facing a classic “chicken and egg” problem: should ETL pipelines or client-facing queries get priority? With the introduction of Redshift Data Sharing, there’s now a more flexible approach — you can create multiple Redshift instances that consume data from a shared source, isolating workloads without duplicating storage. 20:40 - 20:45 - Closing & Final Remarks =================================================== **Very Important: There is no "waitlist" for our regular sessions.** However, there are limited seats available. If you want to make sure you can attend: Register yourself with your "full name" here at meetup.com Arrive on time - seats are first come, first serve. As soon as there are seats available, you are welcome to join with your registration. In case there are no more seats available, we won't be able to let you join us this time.We thank you very much for your understanding! ================================== Additional Information **This event is wheelchair friendly.** Help us spread the word, and invite your friends & colleagues!

AI is changing the way we build software. Agentic Software Engineering takes this a step further. Rather than using AI only for isolated tasks, teams work with specialized AI agents that take on concrete responsibilities across the software lifecycle, from planning and coding to testing and documentation. These agents operate in clearly defined roles and are coordinated through structured workflows. Developers set the goals and guardrails, guide how the agents are used, and review the outcomes. The result is a new kind of collaboration between humans and machines, with a stronger focus on quality, speed, and scalability. The first Agentic Software Engineering Night Berlin will take place on **April 14, 2026**. Join us for two talks by **Torben Keller** and **Johannes Rave**, plus plenty of time for discussion and networking. **Agenda:** 18:30 Open Doors 19:00 **From Vibe Coder to Code Owner** – Torben Keller An AI agent can generate thousands of lines of code in a few minutes. That's powerful – and overwhelming. You can't read and fully understand every line anymore when you want to take advantage of agents. But if you're shipping to production, you own that code. So, how do you take responsibility for something you didn't write and can't fully review? This isn't a new problem. Developers working on brownfield projects face it every day. You join a team and inherit a codebase with hundreds of thousands of lines written by people who left years ago. You don't know every line – yet you ship features, fix bugs, and take ownership. But how? The same principles apply to AI-generated code. What we've learned from decades of working with legacy systems and inherited codebases translates directly to the age of vibe coding. In this talk, you'll learn: * What brownfield development teaches us about owning code we didn't write * How to build an "Agent Harness" that integrates these practices into your AI workflow, ensuring agents follow your rules and standards **About Torben:** *Torben is a consultant at INNOQ, where he focuses on how software teams can work effectively with AI agents. His main area of expertise is the shift from traditional coding to Agentic Software Engineering, in which developers orchestrate multiple AI agents to carry out autonomous tasks across the development process. He also teaches INNOQ’s three-day [Agentic Software Engineering training](https://www.innoq.com/en/topics/agentic-software-engineering-training/) and regularly speaks at conferences and meetups, where he shares practical insights and proven strategies for introducing agentic development approaches.* 19:45 Break 20:00 – **No Constrain, No Gain: Structure for the Agent, Clarity for the Human, Flexibility for the Business** – Johannes Rave AI coding agents are remarkably good at producing code. Whether that code reflects what the business actually needs — and whether it still makes sense to work with six months later — is a rather different question. The temptation is to treat this as a prompting problem — give the agent more context, better instructions, clearer goals. An overlooked lever is paying attention to architecture. When domain logic has its own clearly bounded home, separated from the technical plumbing around it, something interesting happens: the agent stays focused, the human can actually review what matters, and the whole thing remains open to change without requiring a rewrite. This talk shares one approach to getting there — and how some well-placed constraints might set you free. **About Johannes:** *Johannes Rave is a Senior Consultant at INNOQ. He develops LLM-first applications and high-performance web services. He connects design and usability with scalable architecture and operations. Before tech: industrial design, automotive modeling, and running a nightclub.* 20:45 Open End

Please contact me on WhatsApp if you’d like to join our group, as this group will soon be deleted from Meetup. 017684589930 Thanks, Marco We play every Sunday—year-round—and are looking for a few players who are willing to join regularly. Average age is around 27-50. We play on grass using poles as goals, which allows us to adjust the field and goal size depending on the number of players. Please arrive on time, as we need to divide the teams. Game starts 11:30 sharp. Wir spielen jeden Sonntag - ganzjährig - und suchen nach ein paar Spielern, die sich vorstellen können, regelmäßig dazuzukommen. Alter im Schnitt ca. 27-50. Wir spielen auf Rasen mit Stangen als Toren, wodurch wir die Platz- und Torgrösse flexibel a die Anzahl der Spieler anpassen können. Bitte pünktlich da sein, weil wir die Mannschaften aufteilen müssen. Das Spiel beginnt pünktlich um 11:30 Uhr.

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
