**What if your AI agent could decide for itself when to call a tool, or ask another agent?** Welcome to **Sprint #3 of the Agentic AI Engineering Lab**, where we level up from building protocols to building *decision-making agents*. In this hands-on lab, you’ll create an autonomous agent that: * speaks the **A2A protocol** to collaborate with other agents * registers to an agent hub for discovery * connects to an **MCP server** when tools are needed * intelligently chooses ***when to delegate vs when to execute*** No lectures. Just systems thinking + real building. *** ### What We’ll Do * **10:00** \- Quick round of introductions * **10:15** \- Recap: AI Agents\, MCP Protocol and A2A Protocol * **10:30** \- Build your decision\-making agent * **12:00** \- Live demos \+ technical teardown * **12:30** \- Wrap\-up \+ takeaways *** ### What to Expect * Hands-on building, not passive listening * Real agent-to-agent experiments * Collaboration with fellow builders * Fast ideas, quick tests, lots of learning * Unexpected behavior (the fun part) *** ### What Not to Expect * Long lectures * Step-by-step tutorials * Sales pitches * Perfect code This is a **lab**; we learn by building, breaking, and iterating. *** ### ‍ Who Should Join Curious developers, tinkerers, and engineers, with basic knowledge of AI Agents. **Bring:** * Laptop with dev setup * Access to an LLM (Claude / OpenAI / Ollama) * Comfort building small things in any language *** ###

RSVP on Luma: https://luma.com/h4xm63a4 Silent Reading / Creating Club is a gathering for people who enjoy focusing together in public. Bring a book, a notebook, a sketchpad, knitting needles — whatever you’d like to spend a quiet hour with. All projects and all participants are welcome. ​This year is about creating more — quietly, consistently, imperfectly — and shaping environments that support that. If you’re building something of your own, you’re especially welcome here. ​We’re building a community of readers and creators who value depth, presence, and shared silence. The magic isn’t just in the quiet hour — it’s in the people who return and make it feel like a familiar room. ​(Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist.) ​This quiet ritual unfolds at **W66 Café**. ​There’s no entrance fee, but please order at least one item from the café and don’t bring outside drinks 🙂 ​No assignments. No pressure. No productivity race. Just a shared hour of intentional silence, followed by relaxed conversation. 🕰 Our Agenda ​**10:30 – 11:00** Arrivals, ordering drinks/food, light social time ​**11:00 – 12:00** The Great Quiet Hour (Read. Write. Sketch. Code. Think. Sit.) ​**12:00 – 12:30** Optional socializing — share what you were reading or creating, or simply continue in quiet focus. ## **​🏡 House Guidelines** ​To keep this space calm and welcoming for everyone: ​• Silence during the focus hour (no calls or conversations) • Phones on silent mode • If using a laptop, please avoid meetings or audio — headphones welcome • Arrive before 11:00 if possible to minimize disruptions

Für Mitglieder von Text Collective Berlin ist die Teilnahme an dieser Veranstaltung kostenlos. Nicht-Mitglieder werden um einen Teilnahmebeitrag von zehn Euro gebeten. Hier buchen: [https://textcollective.de/ticket](https://textcollective.de/ticket) Es handelt sich um einen moderierten Workshop. Kreative Schreibübung mit anschließender Diskussion zum Erfahrungsaustausch, Inspiration und Motivation zu sammeln. Ein Raum für alle, die kreativ schreiben möchten – egal ob du gerade erst anfängst oder schon länger schreibst. **Jeden ersten Samstag des Monats von 15:00 Uhr bis 17:00 Uhr in der ufaFabrik in Tempelhof.** **Was dich erwartet:** In unseren Treffen arbeiten wir mit abwechslungsreichen Schreibimpulsen, die neue Perspektiven eröffnen und spielerisches Experimentieren ermöglichen. Du schreibst direkt vor Ort, teilst deine Texte mit der Gruppe (freiwillig!) und erhältst konstruktives Feedback. Die Atmosphäre ist offen und unterstützend. Hier darf ein Text noch unfertig sein, eine Idee noch roh, ein Gedanke noch unausgereift. In dieser Atmosphäre gegenseitiger Wertschätzung entsteht der Mut, sich auszuprobieren und die eigene Stimme zu entdecken. Wir lesen einander vor, geben Rückmeldung, ermutigen uns gegenseitig und praktizieren das Zuhören.

Life gets heavy sometimes — and we believe no one should carry that weight alone. This discussion circle is a supportive space where we gather to speak openly about our struggles, mental health journeys, and personal challenges — without fear of judgment. Whether you’re facing anxiety, burnout, grief, or just feeling lost, this is a time for real talk, real people, and real healing. 
We’re not therapists or professionals — we’re humans navigating life, just like you. What we offer is empathy and understanding. 
What to expect:
• Respectful conversations
• Listening without pressure to fix
• Optional prompts to get things flowing
• A calm, welcoming environment 
Come as you are. You don’t need to have it all figured out. 
The event takes place every 2nd and 4th Sunday of the month and is donation based. If possible, please consider helping us cover the location and Meetup expenses with a small contribution. :) Paypal (Friends&Family): mhps.berlin@gmail.com

**Worum geht’s?** Entdecke die Kraft der Worte – in Gemeinschaft. In dieser offenen Gruppe lesen wir gemeinsam kurze literarische Texte – Gedichte, Mikrotexte oder Auszüge aus längeren Werken – und lassen uns von ihnen zum Schreiben einladen. Nach dem gemeinsamen Lesen nehmen wir uns Zeit zum Nachdenken und Austausch. Anschließend schreiben wir 20–30 Minuten Seite an Seite – inspiriert von einzelnen Worten, Sätzen oder dem, was uns gerade bewegt. Im Mittelpunkt stehen nicht handwerkliche Aspekte, sondern das persönliche Erleben, das Gefühl von Verbundenheit und die Funken, die Worte in uns entzünden können – besonders für Menschen, die belastende Erfahrungen gemacht haben, und alle, die auf der Suche nach neuen Perspektiven sind. Wer möchte, kann am Ende den Text teilen, der während der Sitzung entstanden ist – genauso willkommen ist es, einfach nur zuzuhören. Das Teilen ist immer freiwillig. **Die Teilnahme ist kostenlos – und ohne Anmeldung möglich.** **Über die Gruppenleiterin** **[Ingrid E. Johnson](https://ingridejohnson.com/de)** ist Deutsch-Amerikanerin, Gründerin von RECASAS und Peer-Support-Spezialistin. Lesen und Schreiben haben ihr selbst durch schwierige Zeiten geholfen. Schreiben in Gemeinschaft bedeutet für sie eine andere Quelle von Kraft und Inspiration – und genau dieses Erlebnis möchte sie ermöglichen.

Welcome to **I WRITE**, a gentle space for anyone who wants to write—quietly, freely, and without judgement. We are a Berlin community of writers who gather together weekly to write, talk and recharge after a long week. Some of us journal, some write novels, some do academic writing, many people come without a project in mind and see where the inspiration flow takes them. This is a space to simply show up and write, a safe place to be yourself and to release all your layers onto the paper. There’s no set topic, no feedback circle, and no pressure. Just warm people, a calm atmosphere, and time dedicated to yourself. 🗓️ **Agenda:** * 14:30 - 15:00 **→** 30 min arriving, optional socialising (arrive early, meet other writers) * 15:00 - 16:00 **→** 1 hour of silent writing (headphones welcome, focus encouraged) * 16:00–16:30 **→** 30 mins break + optional chat or solo time (stay and chat or go celebrate the rest of your Saturday) * 16:30–17:30 → 1 more hour of silent writing (for those staying) * 17:30–18:00 → 30 mins of chat, and leaving 🎒 **Bring:** * Something to write with (laptop, notebook, phone, typewriter… anything goes) * Something to drink (there is no cafeteria, unfortunately) * Your current project or a blank page * Yourself, exactly as you are **👉 Responsibility:** * Our location is limited; thus, I am kindly asking you to RSVP only if you are willing to attend. **📍Location:** * We meet at **Heinrich Schulz Library in Charlottenburg**. In the library, go look for the Gruppenraum; I will be waiting for you there. Any trouble finding the room, I will come to meet you outside. * 🚇 U7 **Richard-Wagner-Platz** * 🚌 M45 Bus **U Richard-Wagner-Platz** **About me:** Hi, my name is Anastasia. I started this writing club back in May 2025. Since then, it has been hosted weekly at the Heinrich Schulz Library (who is kind enough to allow us to use this room for free). Over this time, I’ve been privileged to meet some of the most creative and kind minds in Berlin. And I would be happy if you joined us. Whether you're an experienced writer or just at the beginning of your journey, you're welcome. If you know how to hold a pen or how to type, there will always be a space for you. Let's write together!

Let's read together on another Sunday morning. Agenda: 10:30-11:00 Arrival, ordering drinks, getting to know each other 11:00-12:00 Reading together 12:00-13:00 Share reading experience There is no books assigned. Just bring whatever you are reading for now. Please sign up only when you can join the event. Hope you will enjoy it there!

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Mental Health, how do you understand it? How can you improve it? How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp. This group is hosted by the Dianetics and Scientology Life Improvement Center of Central Ohio.
