We make landladies and landlords. They buy a flat and pay just 1/4. Tenants and tax cuts pay 3/4. It's not a trick. It's government policy. Our Federal Governments, past and present, want taxpayers to become landlords and landladies, buy property, rent it out to tenants and enjoy passive income later. Come check this out. No strings attached. No sales. Just a meet and greet for orientation. And an after work drink. Wir machen Vermieter. Steuerzahler kaufen eine Wohnung und zahlen dafür nur 1/4. Mieter und Finanzamt zahlen 3/4. Das ist kein Trick. Das ist Politik: Alle Bundesregierungen wollen, dass Steuerzahler Wohnungen kaufen, Mieter reinnehmen und später Beton‑Rente bekommen. Info-Abend nur zur Orientierung. Kucken kostet nichts.

Nice! You are looking for real long time friendship! You might have already lived in Berlin or other big cities and experienced the "Anonymous" culture for a while. Meeting random people over and over and never see the same person again! In order to find "Real Long Term Friendship" in Berlin, do as follows: * You should not care how many people are joining this meetup. You RVSP. Even if only one person is joining. Because if everyone are waiting for everyone else to RVSP, nobody joins and nobody finds a new friend. * You do not care how many people of the opposite sex are joining. You are looking for friends. Finding the best romantic partner in the world, while avoiding not very attractive others, can be your other goal, for another time. Here we are looking for Friends. Real ones. * You are going to risk a very precious property of yours: Your time! Yes, there are thousands of opportunities in Berlin, there might be a rock concert for free, a birthday party you might miss, an important person might call you and invite you spontaneously, but you never find new friends until you decide to risk your time and meet people anyway. "I will check my calendar and get back to you" also does not work. Commit your time and spend it. Trust me, you won't go bankrupt ;-) * You are ready to use your phone as a real phone! You might have been using your phone as a tablet to visit Instagram and Facebook and watch movies. But if you want to find friends, you must know that people might take your phone number and give you theirs. That means they will Call you! And you have to pick up the phone and answer it. If you want to find new friends, you must be ready to do something really hard for the first time after years: Call people first, and if they called you: Answer your phone! * You are going to meet some people twice! That's the point of friendship. We already can experience random encounters with random people in random places one at a time. But that is not called friendship. If you want friends, you must be ready to meet the same person more than once. If you agree with above, RVSP and COME! You will meet other people who think the same way. P.S: Now that you've read all the way down to here, I suggest you [watch this animation](https://player.vimeo.com/video/547249272?h=22f3dd0f6f).

***An Evening of Authentic Relating, Attunement and Connection*** What becomes possible when authenticity and belonging meet? This first Authentic Belonging Circle is an invitation to slow down, arrive more fully in yourself, and explore genuine connection with others. Together we'll create a space rooted in play, supported by clear boundaries, and open to depth. During the evening, we'll explore a blend of Authentic Relating games, partner exercises, embodied practices, and Circling. Some moments may be light and playful, others more intimate and reflective. You are invited to: • connect with yourself and others in new ways • practice deep listening and authentic expression • explore what it feels like to stay connected to yourself while relating • cultivate greater presence, attunement, and belonging No previous experience is needed. Whether you're new to these practices or already familiar with them, you're warmly welcome. The circle is held by Manuela, a systemic coach and facilitator trained in Authentic Relating, Heart IQ, TEPP, and other relational and embodiment-based approaches.

This talk walks through a practical demo of automating the full SRE lifecycle: from incident investigation to deployment validation, using Grafana MCP and the GitLab Agent Platform, and where humans still need to stay in the loop. *Serhii Vasylenko* **The Pipeline Was Green — AI Agents and CI Trust** We’ve spent years building CI/CD pipelines that tell us when code is "technically correct," but are they capable of telling an autonomous AI agent if a change is safe to apply? This talk explores a real-world incident where an AI-powered automation -- pairing Renovate with Claude Code -- successfully executed a "green" pipeline that broke a critical QA cluster for three days, how the team reacted, and how we evolved our vision toward the future of human-agentic collaboration with code. *Frithjof Hoffmann* **Managing Uninvited Guests: Securing Open Source Dependencies** Open source software is the ultimate neighborhood party, but what happens when an uninvited guest slips through the door? This talk digs into the messy reality of dependency hell and its role in software supply chain security: from typosquatting attacks to maintainer account takeovers, and the abandoned projects with known CVEs quietly living in your codebase rent-free.

**The AWS Women’s User Group Berlin** is thrilled to invite you to our upcoming meetup sponsored by Storm Reply focused on **Building production-ready AI agents for real-world impact.** Join us for a deep dive into how to build, observe, and evaluate AI agents at scale. You’ll also see how these ideas come to life in a real-world climate-smart agriculture solution that turns weather forecasts into actionable field guidance. Whether you’re building agentic systems today or planning what comes next, this meetup will give you practical insights into making AI agents work in production. **Speaker Info** **Keynote Talk** **Speaker:** Tetiana Senna **Position:** Team Lead / Senior Project Manager, Storm Reply **Talk Title:** Trust, but Verify: Observability and Evaluations for AWS Agents **Abstract:** Getting an AI agent to work in a demo is easy. Knowing whether it still works in production - after the next prompt change, the next model upgrade, the next edge case - is the hard part. Unit tests don't cover non-deterministic behavior, and manually reviewing a handful of runs doesn't scale. This talk walks through the two practices that close that gap: observability (understanding what actually happened inside your agent) and evaluation (deciding whether the outcome was any good). We'll dig into Amazon Bedrock AgentCore's Observability and Evaluations capabilities, compare the proven evaluation approaches - built-in LLM-as-a-Judge evaluators for automatic quality monitoring, and custom evaluators for business-specific correctness checks - with a candid look at what each one is good for, where it falls short, and what it costs to run at scale. We'll also take a close look at AgentCore Optimization, AWS's newly previewed feature in this space. **Applied Agentic AI Talk** **Speakers:** **Vidhu Mitra Malladi:** Senior Software Engineer, Yara Digital Farming **Chamika Hasanthi:** Senior Software Engineer, Yara Digital Farming **Talk Title:** Weather Risk Intelligence Agent for farmers & Agronomist Abstract: Unpredictable weather events — heavy rainfall, drought, frost, and heatwaves pose significant risk to crop yield and fertilizer efficiency. While forecast data is widely available, it is rarely translated into timely; field-level guidance farmers can act upon. Using AWS AgentCore framework and AI capabilities, we can turn weather predictions into clear agronomic actions, supporting climate-smart agriculture at scale. **You'l learn:** * Implementation of the solution using AWS Agent Core framework * Architecture of the project. 🗓️ **Event Details:** \- Date: Tuesday\, June 30th \- Venue: Storm Reply GmbH\, [address](https://www.google.com/maps/place/Storm+Reply+GmbH/@52.5012692,13.368852,17z/data=!3m1!4b1!4m6!3m5!1s0x47a851119af460c5:0x35e34ba578e8b1ec!8m2!3d52.5012692!4d13.368852!16s%2Fg%2F11gg9298pv?entry=ttu&g_ep=EgoyMDI2MDUxNy4wIKXMDSoASAFQAw%3D%3D) \- Time: 06:00 PM \- 9:00 PM Doors open at 6:00 PM Food & drinks will be provided. 📋 **Program Schedule:** **18:00** \- Registration and Welcome Networking **18:20** \- AWS Women's User Group Welcome **18:30** \- "Trust\, but Verify: Observability and Evaluations for AWS Agents" **Speaker:** Tetiana Senna, Team Lead / Senior Project Manager, Storm Reply A practical session for anyone working with AI agents on AWS who wants the confidence to put them in front of real users.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
