Fly High: Join Drone Events in Berlin

Flutter Berlin × CarOnSale
Thu, Jul 9, 4:30 PMJoin us for an evening of Flutter, Dart, and networking hosted by CarOnSale. We'll kick things off with a deep dive into one of Dart's newest language features, followed by a second session and plenty of time to connect with fellow developers from the Berlin Flutter community. **Schedule** **18:30 — Doors Open** Check in, grab a drink, and meet fellow Flutter developers from the Berlin community. **19:00 — Welcome Notes** A short introduction from Flutter Berlin and our hosts at CarOnSale. **Talk 1 — Hiding Complexity with Dart Extension Types — Roman** Extension types in Dart 3.3+ let you elegantly hide the real complexity behind clean abstractions. They enable powerful patterns for true compile-time singletons with strong privacy guarantees, while also letting you build robust zero-cost Value Objects that enforce domain invariants and create a clear ubiquitous language — all with zero runtime cost. **About Roman** Roman is a Google-awarded Flutter Developer and Staff Mobile Engineer at CarOnSale.de, where he has worked for 4 years as part of his 8 years of Flutter experience (and over a decade in design). He loves Dart as his primary language and Rust as a complementary one (along with TS/Swift), but believes strong programming fundamentals matter more than any specific syntax. In his role he mentors Flutter developers and shapes architecture solutions. Outside of work he prioritizes family and open-source. **Talk 2 — TBA** Our second session of the evening will be announced soon. **20:30 — Networking & Socialising** Meet fellow Flutter developers, exchange ideas, discuss the talks, and connect with the local community. **22:00 — Doors Close** We wrap up the evening and head home inspired with new ideas and connections.

Square Tomatoes and Robot Bees - Who decides?
Tue, Jun 30, 5:00 PMYou don't have to sign up-just stop by. Tea, coffee, water, beer, wine, and pizza will be available throughout the evening. --- -- Most conversations about AI skip the part that is crucial: **who it's built for, who pays for it, and who doesn't get a say**. This evening goes exactly there. We start in 1960s California, where scientists bred a new kind of tomato: square, hard, machine-ready, and wiped out 82% of the state's tomato farms in the process. Farmworkers and small farmers sued the university behind the technology, arguing they were being forced to fund their own replacement. They lost. But the questions they raised never went away. Today, researchers are using AI, robotics and gene editing to create tomatoes that can be pollinated by robots, crops designed for automated production systems, and even new traits engineered for consumer preferences. AI is having an impact on agriculture, food production, and labour, often with public money, rarely with public input. Sounds familiar? **What to expect** A 90-minute interactive evening: * **Opening talk** connecting the tomato harvester story to today's AI developments * **Live audience polling** * Conversation with **Ildi Carlisle-Cummins** (California Institute for Rural Studies): storyteller, oral historian, and director of the Cal Ag Roots project, one of the organisations that grew out of the original lawsuit * Open audience **discussion** * **Informal networking** to close **What you'll take away** A sharper way to think about who controls the technologies influencing our food, our work, and our world, and what citizens can actually do when change feels inevitable. If the phrase "square tomato" sounds too strange to be true, you're not alone. Even the TV detective [Mr. Monk couldn't believe his eyes](https://youtu.be/VtO-97pl7cA?is=VnMxtacAwL1IChub)! **Free to attend, free of jargon, no expertise required.** **Just bring your curiosity.** *Hosted by [Save Our Seeds](http://www.saveourseeds.org/?utm_source=luma) and [Human-Future-Hub](https://humanfuturehub.org/?utm_source=luma) Berlin* Tea, coffee, water, beer, wine, and pizza will be available throughout the evening.

AWS Women's User Group Berlin: June Event - AI Agents in Production
Tue, Jun 30, 4:00 PM**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** **Speaker:** Vidhu Mitra Malladi **Position:** 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.
