Hello friends! We are the team of CaféIN, an inclusive café in Spandau, inviting you to our German language café - Sprach-CaféIN! 😎 With our language café, we aim to create a safe space for everyone to practice real German, without boring grammar exercises and books, but over coffee, conversations and new encounters :) Every person will be warmly welcome at our Sprach-CaféIN, regardless of background and origin. We are happy to see each and everyone of YOU! Our events are not about politics, as we aim to build bridges and bring people together through language and culture. Participation is free, but every participant is **required** to order at least one drink or snack at the café. This helps us support CaféIN and keep this special place alive.

„Die haben das doch vorher geübt!“ Wer sich schon einmal Impro-Shows angesehen hat, kann es oft nicht glauben, dass die Geschichten, die Verwicklungen, die Pointen oder auch die Lieder tatsächlich im Moment des Spielens entstanden sind. Sind sie aber! Wir spielen seit über einem Jahr zusammen, sind darüber eine Gruppe geworden - die Spontansen - und treten ab und zu auf. Wer schon etwas länger Erfahrung im Improtheater mitbringt, kann gerne vorbei kommen, reinschnuppern, vielleicht dabei bleiben…bitte vorher anmelden unter [Fabianherrmann1979@proton.me](mailto:Fabianherrmann1979@proton.me) Teilnahme auf Spendenbasis. Wir entdecken spielerisch, achtsam und mit viel Spaß die Welt des Impro-Theaters.

Join us for chill **indoor** beach volley! 🏐 🏐 🏐 This event is for everyone who enjoys chill games and is not a *complete* beginner (A1.5+). We play 3v3 (or 4v4) with beach rules. There are no trainers at this event. Register via [the simultaneous event](https://www.meetup.com/berlin-volley/events/) for higher-level 2v2 matches (F1+). After playing, you can join us for socials with drinks and snacks at the bar area. We often play a social deduction game, which you're also welcome to join. We play in domes that are heated up to at least 15C. It's recommended that you come 10 minutes early so you have time to change and find the fields. If it is your first time, 15 minutes might be even better. You can join whatever court you like and move between courts during the event. We self-organize, so once you finish a game, you can start a rematch, mix with another court, or take a break as you see fit. Upon arrival, join the warmup happening on one of the courts. Join our WhatsApp community via [https://volley.berlin/WhatsApp](https://volley.berlin/WhatsApp) ([QR code](https://secure.meetupstatic.com/photos/event/b/f/d/5/highres_532249109.webp)) Follow us on Insta at [https://www.instagram.com/berlinvolleyball](https://www.instagram.com/berlinvolleyball) **Rules**: Do not join if you have an infectious disease. For everyone's safety, we do not allow kicking the ball during games with beginners. Be respectful of your fellow players. **Venue**: We play at BeachMitte. There are changing rooms, toilets, and hot water showers that cost 1 EUR. There are no lockers. There is a bar that sells drinks and snacks. **Payment**: You pay in advance via Meetup. Payment via PayPal or Urban Sports Club is not possible. **Refunds**: The venue does not provide refunds. Thus, we cannot refund you either, even if the event is canceled due to bad weather. If you know you can't make it in advance, you can try selling your spot to someone else via WhatsApp or the comment section. In the rare cases that we cancel an event due to poor attendance, everyone gets a full refund. Pictures might be taken and shared publicly, such as on Meetup or Instagram. You can opt out by letting the organizer know you do not wish to be photographed. By RSVP'ing to this event, you acknowledge and agree to the following: Participation in this volleyball event is at your own risk. The organizer is not responsible for any injury, loss, or damage sustained during the event, whether caused by negligence or otherwise.

**Agentic AI Engineering Lab (Tech Event, Sprint #1)** **\- Build a Production\-Ready MCP Server** **Move from prompting to architecting** The Model Context Protocol (MCP) is an emerging open standard for connecting AI apps/agents to real tools and data sources. This session is not a talk — it’s a hands-on lab where we build MCP servers that can be tested immediately with an MCP-capable client (e.g., Claude Desktop / your preferred agent setup). **The Format** We are planning a series of agentic ai tech meetings for deep building. This event may be attended alone or be seen as part / sprint of the event series with upcoming events building on top of what we build here. This is a high-density micro-meetup limited to 6 seats. We prioritize builders: bring your laptop, ship code, and be ready to 'build and break' alongside other devs and engineers. **Future Sessions building on top may focus on ...** RAG systems, advanced MCP features, A2A, multi-agent workflows, production deployment Patterns or whatever we feel nice to build next. (We run our sessions like an anthology series: **Every meetup is a standalone sprint.** While we often build on previous results, each session provides a complete experience and remains fully accessible to first-time attendees.) **What you'll build** After a quick alignment on the technical scope, the floor is yours: build your solution using the stack and tools that fit your workflow. We provide the framework; you provide the execution. By the end, you’ll have a working MCP server (Python or TypeScript) with at least one real tool/resource, tested end-to-end. **Ideas: Choose one track (or bring own idea if it fits the scope)** **For Beginners (Foundational)** * Personal knowledge server (local files/notes) * Weather / external API integration * GitHub issues helper **Intermediate** * SQLite query interface * Slack/Discord notification tool * CSV/Excel analyzer **Advanced** * Multi-API aggregator (e.g., calendar + weather + tasks) * Document processor (PDF/DOCX parsing) * Lightweight system monitoring/control **Schedule (Saturaday, 10:00 - 15:00 CET)** * **10:00–10:30 — Foundations + Live Demo** Quick run through general MCP architecture (hosts/clients/servers), core primitives (tools/resources/prompts), basic patterns in order to get everybody on the same page. * **10:30–11:00 — Environment Sync** We wanna make sure everyone can run a “Hello World” MCP server (Python or TypeScript). * **11:00–12:45 — Build Sprint (Lab Time)** Implement your server + first tool/resource. Pair-debugging encouraged. * **12:45–13:00 — Break (Pizza/Snacks)** * **13:00–13:30 — Test & Iterate** Use MCP Inspector / your client to test, fix edge cases, tighten tool contracts. * **13:30–15:00 — Demos + Technical Teardown** Quick demos, what broke, what worked, and what we’ll harden in the next sprint. **Prerequisites (Please Read)** * You’re comfortable shipping small things in your preferred dev language and tools (e.g. Python, TypeScript/Node.js). * **Bring your laptop** + basic dev setup (Git, package manager). * Have access to an LLM client / API (Claude/OpenAI/etc.). * This is a lab for engineers, not a tutorial. We solve architectural problems together, but you are the master of your own dev environment. * **Mindset:** Build, Break & Iterate — broken code is welcome, passivity isn’t. **Logistics** * **Location:** Our private boardroom in the Grunewald area (near Martin-Luther Hospital). The exact address will be shared after RSVP. * **Capacity:** 6 seats (first come, first served; deposit required) **Commitment Deposit and No-Show / Late-Show** This meetup is strictly non-profit. To respect everyone’s time and ensure all 6 seats are utilized by committed builders, a €15 deposit is required. * **The Deal:** The deposit covers high-quality pizza, snacks, and drinks. Any surplus will be refunded to you via your original payment method after the event. * **Punctuality is Key:** We start at **10:00 sharp** with the technical foundations (door open from 09:45). To protect the group’s focus, late arrivals or no-shows will not be eligible for a refund. Their deposit will be fully contributed to the community's pizza & snack fund. * **Cancellations:** No refunds for cancellations within 24 hours of the start time.

Join us for intermediate and advanced play on **indoor** 2v2 courts. If you are not yet at the intermediate level (F1+) or want to play 3v3/4v4, sign up via [the simultaneous event](https://www.meetup.com/berlin-volley/events/) instead. We play with beach rules: do not use open hands for the first or last touches, do not touch the net, etc. We overbook slightly to ensure we have enough players and to allow individuals to take breaks. After playing, you can join us for socials with drinks and snacks at the bar area. It's recommended that you come 10 minutes early so you have time to change and find the fields. If it is your first time, 15 minutes might be even better. We play in domes that are heated up to at least 15C. You can join whatever court you like and move between courts during the event.

📅 **Week 4 Focus: Calling LLM via API** Each 7-week cycle focuses on a small, well-defined part of a larger system—and over time, these cycles build toward a complete, real-world project Feel free to join at any week and we will catch you up. There is no need to be at the beginning of the cohort to build. Complete beginners welcomed! 📌 By the End of a Full Cycle, You should Have 🎯 A working project in your own GitHub repo 🎯 A small but real portfolio piece you can demo or write about 🧠 **Current Project** This cycle’s shared project is an **image-based knowledge extraction system**. In Week 3, we trained a deep learning object detection model (YOLO) and learned how modern computer vision models are built. **In Week 4** we will try **LLM-based image understanding via APIs** to extract structured information from images and comparing this approach with traditional computer vision and building your own deep learning methods. * \*\*\* **👋 Who Is This For?** 🔹 Beginners who learn best by doing — no prior experience needed 🔹 Career switchers from product, engineering, design, marketing, or other fields who want to break into data 🔹 Analysts, engineers, and PMs looking to sharpen their skills or build real-world projects 🔹 Data professionals who want a creative playground outside of work 🔹 Anyone with big questions and a love for learning through experimentation \*\*\* **BUILD.

Can two girls—one enchanted, one the enchantress—save their kingdom and each other? Two hundred years ago, a slighted deity stole the magic from Auréal and vanished without a trace. But seventeen-year-old Odile has a plan. All her life, her father, a vengeful sorcerer, has raised her for one singular task: infiltrate the royal palace and steal the king’s crown, an artefact with enough power to restore magic. But to enter the palace, she must assume the identity of a noblewoman. She chooses Marie d’Odette: famed for her beauty, a rumored candidate for future queen…and Odile’s childhood-friend-turned-sworn-enemy. With her father’s help, Odile transforms Marie into a swan and takes her place at court. But when the king is brutally murdered and her own brother is accused, her plans are thrown into chaos. Desperate to free her brother, Odile is forced to team up with none other than elegant, infuriating Marie, the girl she has cursed…and the girl she can’t seem to stop thinking about despite her best efforts. To make matters worse, there are whispers that the king’s murder was not at the hands of man, but beast. Torn between loyalty to her father and her growing feelings for Marie, Odile becomes tangled in a web of treachery and deceit. To save her kingdom, she must find the true path to magic…and find the real killer before they—or it—strikes again.
