This year we have our very own big covered tent on the silent green lawn from 13–15h on Sunday May 10. To gather, chat with each other and have a nice day together! It’s public open day, completely free APART FROM THE SCREENINGS, WHICH COST 6€/hourlong screening (not related to our group of course) There’s a character art market, an art exhibition, collage workshop, picture book readings, and 6 screenings plus a Kids Kino.

During this hike, we’ll take a look at what has changed over the winter (in case you joined us on this hike last year on 3 October). As in autumn, we will meet at Friedrichshagen S-Bahn station (on the platform, east exit) and start the event with an ice cream from a famous ice cream place on Bölschestraße. Then we will hike through the Erpetal, across woods and fields, into the outer districts of Berlin (https://www.komoot.com/tour/2936165603). If you don't like ice cream, please arrive at the S-Bahn station Friedrichshagen at 13:30 am instead. We will pick you up at the corner of Fürstenwalder Damm and Dahlwitzer Landstraße. To the north-east of the station, there is an area with benches and a toilet. On Google Maps, the toilet is indicated as 'Berliner Toilette S-Bahn'. We will pick you up at this spot. If you need to contact other participants during the hike (for example, to find out where to meet us if you are running late), please use the Signal group link that I will send to all participants via private message three hours before the hike. This timing is intended to prevent non-participants from misusing the link for unwanted advertising, which has happened in the past. Signal allows us to share our locations during the hike without involuntarily forwarding this information to the intelligence services of authoritarian or non-authoritarian states, but unfortunately the location sharing function does not include tracking, i.e. no continuous updates. For all other purposes, especially socialising and posting photos, please use the Telegram subgroup 'Event Chat & Photos': https://t.me/addlist/KAOk2PA4BDE0ZTY8 . The hike will take place if at least 6 people sign up. As long as there are more than 6 people, you can sign up and cancel as many times as you like. If there are 6 or less people, please avoid cancelling, as this might make the other participants feel insecure about whether the hike will take place (or whether there is something wrong with the hike and they should cancel as well --> Matthew effect - Wikipedia). If there are less than 6 participants, the hike will also take place unless the majority of the participants are in favor of canceling the hike.

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. Table 5d

Let's meet for the [ACX Spring Meetups Everywhere 2026](https://www.astralcodexten.com/p/meetups-everywhere-spring-2026-times) in the Humboldthain! This will likely be a big meetup, as it was announced by Scott on ACX. From experience, I expect 25–50 attendees. Humboldthain is good to reach by public transport; the next train stops are S+U Gesundbrunnen and S Humboldthain. If you’re reading this, you’re invited. Please don’t feel like you "won't be welcome" just because you’re new to the blog, demographically different from the average reader, or hate ACX and everything it stands for. You'll be fine! I'll buy some snacks; feel free to bring something to share as well. There are also many restaurants around if you get hungry. Location: Big lawn at the center of Humboldthain — [https://plus.codes/9F4MG9WP+36](https://plus.codes/9F4MG9WP+36) Contact: Reply to this event, message me here on Meetup, or join the Telegram group below.

Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**

**Book 1-4 seats by mail with your full name an mobile-number to [weinkueche@gmx.de!!!](http://weinkueche@gmx.de!!!/) No mail, no confirmed booking!** Over the years, we've collected more than 1.500 wines on our wine tours and stored them under optimal conditions. We particularly enjoy aging our more expensive premium wines for a longer period, as they only reveal their full potential after several years. "Baby killers" is the nickname given to wine drinkers who consume these premium wines far too young—a term that applies to almost all Grand Cru (Großes Gewächs) wines available in stores or restaurants. We want to open wines with you that have been allowed to mature and have reached their optimal drinking window (after 5-10 years). Unlike with young wines, you'll be able to say: **It doesn't get any better than this!** ... Just different... After this event, you'll also want to start cellaring your own wines, because the difference in taste will convince you! What´s the WeinKüche-Winetasting about? You and max. 14 other wine fans will be able to taste 10-12 different Wines with a full "Brotzeit" or small dishes in our private flat in Berlin-Mitte…. The best way to end a weekend! The event will be moderated in german and/or english. Über die Jahre haben wir auf unseren Weinreisen viele viele Weine gesammelt und bei sehr guten Bedingungen eingelagert. Insbesondere höherpreisige Spitzenweine lassen wir gerne etwas länger reifen, da sie ihr Potential erst nach einigen Jahren offenbaren. "Babymörder" ist der Name für Weintrinker, die Spitzenweine viel zu jung trinken... was eigentlich für fast alle GG zutrifft, die im Handel oder in der normalen Gastronomie gekauft werden können. Wir wollen mit Euch Weine öffnen, die reifen durften und ihr optimales Trinkfenster (nach 5-10 Jahren) erreicht haben. Anders als bei den Jungweinen wird man hier sagen können: **Besser wird´s nicht!** .. Nur anders... Nach diesem Event werdet Ihr privat auch anfangen, Weine einzulagern, denn der geschmackliche Vorteil wird Euch überzeugen!

One of the few concepts in the world which every religion, creed, group etc agrees on is that our time on this planet is limited. Whatever happens to you after that, the stories on that vary from person to person, group to group, but the inevitability of your physical body's limitation is agreed upon by everyone. Yet, no one wants to talk about it, to contemplate, how awareness of one's mortality has influenced whole of human civilisation. Even the oldest known literature, Epic of Gilgamesh, is a story about a man/demi-god, wanting to conquer death and achieve immortality, fails to do so. Life and death have existed side by side closely since forever. It was just more visible before modernity, because of less advanced medicine, less tamed nature etc. Today? Well, its the last topic on most minds. Hence, for this meetup, our topic would be simply, "On mortality". I have found a cozy little cafe (The cafe has great homemade cakes by the way) near a peaceful cemetery. Why a cemetery you may ask? And how can it be "peaceful"? A cemetery may remind you of decay and depression, but instead, it has life all around. Small insects running their society, (if you look closely 😏), flowers, trees, melodic chirping of birds, and the beautiful sunlight tearing through the trees. It has that contrast of and life and death coexisting so close to one another, which today's human's living in so much safety and certainty mostly get repelled away from and hence avoid discussing about it, is the major theme of this discussion.

**Join us for a swim at Stadtbad Tiergarten Pool (near Hauptbahnhof)!** Hey everyone, We are doing a casual non-professional swim. It's an indoor heated (+26°C) pool, and I'd love for you to join us!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City. He has worked there for 17 years, serving previously in the roles of Data Analyst, Programmer, and Operations Coordinator.
