Hi everyone. We'll meet and play a relaxed game of ultimate in Volkspark Rehberge if the weather cooperates. Our games focus on having great team play, where the teams work together to advance the disk down the field. It's more important to work well together as a team than have a few star players get a point with lucky shots. For this reason, players of all skill levels (especially those who have never played) are welcome to join Bring plenty of water, shoes you can run in and comfortable clothing that can get a bit dirty. Although we're an established group, newcomers are always welcome. After the game we try to spend some time together and have fun. Finding us: We meet in this big grassy area, it's a short bike ride from the subway stop Rehberge on the U6 or Amrumer Strasse on the U9. It can be a bit tricky to find the first time, so we've got a few methods to help out (don't trust the meetup map pin, it often shows some point in the park, not the exact spot where we are) 1.

***Join us this summer to hike in Eifel National Park and discover Monchau and the Holy Roman town of Aachen.*** **HOW DO I JOIN THIS EVENT?** Click on link below to get complete info and to sign up for this event by getting your ticket. [https://urbanaturetravel.com/event/monschau-eifel-national-park-hiking](https://urbanaturetravel.com/event/monschau-eifel-national-park-hiking) **SPECIAL OFFER FOR NEW USERS** * 10% New User Discount using promo code: **MEETUP10** * Valid for this trip or any other trips available on our website. **WHY GO?** Fire, water, air and earth. Almost no other region in Germany is dominated by the elements as much as the Eifel uplands. The landscape reflects the geological development of millions of years in fast motion: valleys crossed by rivers, the cones of extinct volcanoes, dry maars which have become moorland, bizarre rock formations and layers of different hill ranges. The Eifel region was settled by Celts, Romans and Franconians amd the the products of their cultures are still there to be admired: romantic towns such as **Monschau also know as the "Pearl of the Eifel"**, with half-timbered houses dating from the Middle Ages, the fascinating remains of Roman structures and imposing castles such as “Burg Eltz”. The town is also surrounded by beautiful countryside and is a great base for hiking and outdoor activities. **WHAT ARE SOME OF THE HIGHLIGHTS?** * **Exploring Monschau "Pearl of the Eifel":** Charming and picturesque village with preserved half-timber houses in the Eifel mountains on the Rur River Valley. Monschau exudes with history, architecture & romance. * **Hiking in the Eifel Region:** This region was shaped by volcanic activity and although the last volcano erupted about 10,000 years ago, evidence of the Eifel’s turbulent past can be seen in the crater lakes, called maars, that pepper the Vulkaneifel landscape. The region also boasts some of the loveliest fairy tale towns and medieval castles in the country. * **Short Guided tour of Aachen:** Aachen is known for its history and culture, as well as its thermal springs and spa. The city was the preferred residence of Charlemagne, and was the place where **31 Holy Roman Emperors** were crowned Kings of the Germans. It's also famous for **Aachen Cathedral**, a **UNESCO World Heritage Site**, which was built in the 8th century and is considered one of the most important examples of Carolingian architecture. * **Aachen Cathedral:** Aachen Cathedral was the very first site to be granted **UNESCO World Heritage** status in Germany, and with good reason: built in around 790 to 800, the cathedral is of world importance in terms of the history of art and architecture, and is one of the great examples of church architecture. The final resting place of Charlemagne, it was also where German emperors were crowned for 600 years. * **Aachen Thermal Baths (Optional):** In Aachen, water and wellness have a long tradition. While in former times, the Romans relaxed in the therapeutic waters of the Aachen mineral springs, today, the Carolus Thermen thermal pools offer the perfect escape from everyday life. Perfect way to finish the day. **TRIP DETAILS** **Start & End Date:** Saturday, 4 July 2026. **Meeting Location & Time:** * **Option A:** Dusseldorf Hbf at 7:00 am on Saturday morning. * **Option B:** Meet outside Aachen Hbf at 8:30 am on Saturday morning. * **Note:** Exact meeting location will be provided in the WhatsApp group for this trip. **Finishing Location & Time:** * **Option A:** Dusseldorf Hbf at 10:00 pm. * **Option B:** Aachen Hbf at 8 pm. **Hiking Distance:** 15 km – Hiking in the Eifel uplands & exploring Monschau - "Pearl of the Eifel" & Aachen. **Hiking Difficulty:** Easy to Intermediate – Hiking at relaxed pace on well-marked paths, moderate/low elevation, no experience required. **What is Included ?** * Community Guide & Leader for the entire trip. **Note:** English is the main language spoken in the trip. * All public transportation from the meeting location to the finishing location (Based on the ticket option selected). * Short guided tour of Aachen city. * Short guided tour of Monschau "Pearl of the Eifel". * Guided hike. * Access to a Google photos album dedicated to this trip, where you can share all your amazing pics & videos. * Access to a WhatsApp group only for the confirmed participants. **Where is Aachen located?** * One hour by train from: Dusseldorf & Cologne. * Two hours by train from: Brussels. * Three hours by train from: Amsterdam. **WHAT IS THE PLAN ?** 🕖 **7:00 AM – Meet at Düsseldorf Hbf** Meet your guide and fellow participants at Düsseldorf Central Station before departing towards Aachen. 🚆 **7:15 AM – Train to Aachen** Enjoy a relaxed morning train journey through western Germany. 🏛️ **8:45 AM – Arrival in Aachen** Meet the rest of the group joining from other locations before continuing together towards Monschau. 🚌 **9:15 AM – Bus Journey to Monschau** Scenic ride through the beautiful Eifel region. 🏡 **10:20 AM – Arrival in Monschau & Start Hiking** We begin our scenic 14 km hike through picturesque forests, river trails, and rolling hills surrounding Monschau. 🌲 **12:30 PM – Forest & Riverside Trails** Follow the beautiful Rur River through peaceful woodland paths and rocky landscapes. 🥪 **1:30 PM – Lunch Break with Scenic Views** Relax and enjoy a break surrounded by the beautiful Eifel countryside. ⛰️ **2:15 PM – Hilltop Viewpoints over Monschau** Climb to panoramic viewpoints overlooking Monschau’s famous half-timbered houses and valley landscapes. 🏘️ **4:00 PM – Free Time in Monschau** Explore the charming old town, cafés, bakeries, and the famous “Venice View” of Monschau. 🚌 **5:00 PM – Bus Back to Aachen** Return journey through the scenic Eifel countryside. 🏰 **6:30 PM – Aachen City Walk** Discover one of Germany’s oldest cities, once home to Emperor Charlemagne and the coronation site of Holy Roman Emperors. ♨️ **8:00 PM – Optional Thermal Bath Visit** Relax and unwind at Aachen’s famous thermal baths or enjoy free time in the city center. 🚆 **9:00 PM – Train Back to Düsseldorf** Begin the return journey home after a full day of hiking, history, and beautiful scenery. 🕙 **10:00 PM – Arrival at Düsseldorf Hbf** End of the trip. **FOR FUTURE TRIP UPDATES** Please do join our WhatsApp / Telegram channel for updates about our future trips including possible early bird discounts, contests etc. 1.

1 EURO DONATION FEE PER PERSON IS REQUIRED (on site, in cash), to pay back the Meetup subscription fees and support my Events. READ THE DESCRIPTION WITH THE INFO (IMPORTANT). We take a walk in Berlin to meet new people or people we already know 😁 It's a way to spend a few hours together on a Sunday afternoon. **How it works?** The concept is very simple: * We meet at Alexanderplatz Station at 14,00 o'clock (we use the Whatsapp Chat to find each other: I will post there my exact location in the station) * I wait for people for 10 minutes, till 14,10, then we start to walk direction West, crossing Museum Island and Mitte 🏛️🏘️ * We reach Tiergarten and we will cross the entire park, seeing some of its interesting points🌲🌳☘️ * We finally reach Café am Neuen See: https://maps.app.goo.gl/kSui84icxyU6hQG56 to sit down together to take something to drink or eat 🥐☕🍪 * The total length of the walk is about 8kms I consider that the event will last in overall around 4 hours (2 hours of walk and 2 hours at Café am Neuen See), but people are free to stay together longer, if they want 🙂 What I provide is leading the walk and the people at Café am Neuen See, but I do not force anyone to stay shorter or longer. I do not provide a "personal support" for people who arrive after 14,10 (do not write to me expecting "private support"). You are responsible to check for the weather and decide if come or not. Thanks for understanding. If you have to contact me, make it via Whatsapp, not here on Meetup. WHATSAPP GROUP 💬 to find each other (join it, we use this group to find and synchronize us) [https://docs.google.com/document/d/157uLVXObKt1a4NqqvPa09NJW-050YBwHLW-7DbOD8R8/](https://docs.google.com/document/d/157uLVXObKt1a4NqqvPa09NJW-050YBwHLW-7DbOD8R8/)

**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.

Join us for our second hike of the summer! We will start by meeting at (or at least boarding) the **10.40 RE2 (3112)** at **Ostkreuz** station, **Platform 1**. We will arrive at Lübben (Spreewald) at 11.25. *Note that if you miss this train, then the next one does not arrive until 11.56, so you will certainly miss us and won't be able to catch up!* The hike will go from Lübben to Schlepzig, along the canals and lakes of the beautiful Spreewald region. *(See photos for a rough route -- this is not necessarily accurate!)* The walk will be about 15 km and take about 4-5 hours. Bring lunch, snacks & water, comfortable walking shoes, and maybe even some sunglasses. We will stop a couple of places along the way, but will not stop long enough to order food, so bring your lunch! At the end of the walk, in Schlepzig, there is a Whisky brewery and a Biergarten. We will visit one or both. You can also get food at both. Then, we will take the 18:57 bus back to the starting point of Lübben Bahnhof. From there, we will catch the 19.34 RE2 (3129) back to Ostkreuz, arriving at 20.23. *(If you really want to, and if we get to Schlepzig in time, then you can also take the 16.52 bus to Lübben, then the 17.34 RE2 back to Berlin.)* **Note: We will reschedule this if the weather is too rainy. So definitely check back here before going!**

Join us for a 2.4 mile hike along the Alum Creek Trail south from Casto park to Strawberry Farms park and back. This is a fully paved flat trail along Alum Creek. Come and enjoy a great hike with us!

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.
