You've seen them in the book shop. You've seen them in the library. You've seen them online. **The Blind Date with a Book.** Those shelves of wrapped books with little teasers written on them. This is the book trend perfect for Valentine's, and perfect for a swapping group like us! For this special event, please bring a wrapped book. On the front please write: * the language of the book * a few short bullet points about the book. Get as creative (or not) as you like, as long as it's a truthful description. I've seen fascinating paragraph versions and also one liners. * For example: "You will love this book if you love -similar author / general genre / band-singer the book reminded you of / actor who played the lead in the film / etc-". Other examples include writing the first line of the book. Or your favorite line of the book. Beside that, it's just similarly structured as the "classical" bookswap: * We put the book(s) we brought down on the tables. * Each book gets a post-it so people interested would write their names on. * We browse and discuss the books with one another while sipping coffee or hot chocolate, or eating cake. THIS TIME try to avoid naming the book and author. * We write our names down on any books we’d like to take home. * At the end of the evening, negotiate any books that are contended and take a new-to-you book home! I've mostly only seen the trend at book stores and Libraries and when I just Googled it, saw that a lot of people are totally tricking the wrapping out. Please don't bother going that far unless it would give you great pleasure. We'll have some newspaper / paper bags on hand if you don't have any wrapping. ***NOTE - this is NOT a person dating event.*** We tried that once as a very optional part of the event and it wasn't fair to the three confused people who were looking for people and not books. We know of at least one book swap marriage and several other book swap relationships so it happens organically without us pushing for it and making it all awkward :) Similar to our pleasant swapping post-it format, our expectations below apply to this event as well. We look forward to swapping with you! GROUP EXPECTATIONS for PLEASANT SWAPPING * Please bring a book! It's not that you bring one you take one, but do try your best to bring something. * Books stay on the tables, open for sharing, until you are ready to leave so that everyone can have a look. We are notably not first come first serve. Please wait until you are leaving to bag the book. * If two or more people want the only copy of a book, negotiate. Maybe one of you reads it first and then gives it to the others. Or perhaps they have found another book instead. Or leave it to fate and toss a coin. The best part: now you have found somebody whose taste you can really admire. In any case, please don't walk away with a book with several names on it without letting the others know. These negotiations are fun and easy, so don't shy away from a book because there's already a name on it, and feel free to put your name on as many books as you find interesting. It's not that you bring one you take one; you may take as many as you can negotiate. * Political discussions with consent: make sure the people you are talking to would like to have a political discussion with you. * Please respect this space as first and foremost a community for connecting readers over their love of books and reading, stories, and narratives of all sorts. Please be respectful of tastes and opinions. * If something is bothering you, please reach out to the organizers, and we'll do our best to resolve it. * Lastly, don't expect your book back. It will find a new home. If you love it, let it go. **Major LANGUAGES (and genres) of this meetup:** English, German, French, Spanish, Italian; Fiction, Non-Fiction, Serious Reading, Light Fun, “classics", Krimis, Booker winners, Sci-Fi, Fantasy, Self-Help and more. You never know who can read what languages, and there's no accounting for taste. We are a delightful and international group of readers. We look forward to swapping with you!

📅 **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. LEARN. EXPERIMENT. OVER COFFEE.** Come hang out, meet like-minded people, and work on something fun. 📍 Based in Berlin – in-person meetups only (for now!) 💻 Laptops + ☕ highly encouraged Join our Discord → [https://discord.gg/dPnmzcCP8w](https://discord.gg/dPnmzcCP8w) Check out our program resources: [Google Drive](https://drive.google.com/drive/folders/15DmZqD4bLBk2vU4zpvh1HiB3_5n09v-q?usp=sharing) \*\*\* ✨ Who’s Hosting? I’m Lindsey, a senior data scientist working on AI, causal inference, and data products. I’ve built models for fraud detection, uplift modeling, and LLM-based systems. I am always open to suggestion for different format for this meetup.

Welcome! This football session is for individuals who like playing on moderate to high intensity (run a lot and change position to give player with the ball option to pass). Usually play on a pretty competitive level. Our football skills are average to good. To keep things fair and enjoyable for all, we follow a few simple rules: * **Show up at 07:45** so that you can get checked by the organiser * If you are not checked by the organiser then \*\*1 match penalty applies\*\*(being moved to waitlist) * **No studs** * If you show up with studs, then you wont be allowed to play * No dangerous tackling * If you get tackled, you need to call the foul * In case of handball only people close (1-2m) can call handball * Since we play 12v12, we have offsides (0-1m difference is still tolerated) * No penalties for handball in penalty box(no way of proving handball and please be fair) * In case of handball, the other teams goalkeeper gets the ball

Silent Book Club is a group of book lovers who enjoy reading together in public. All books and all readers are welcome. (Kindly RSVP 'yes' only if you can make it, so we can save a seat for you and our fellow readers on the waitlist!) This page-turning party will unfold in the Café (1st floor) at the Bode Museum. There's no entrance fee, but please order at least one item from the cafe and don't bring any outside drinks :) No quizzes, no pressure, no assigned books - just a group of book-loving souls basking in the beauty of silent reading. **Our thrilling agenda:** 10:30 am - 11:00 am - Arrivals, ordering drinks/food (social time) 11:00 am - 12:00 pm - The Great Quiet Reading Hour (where silence is the star) 12:00 pm - 13:00 pm - Optional socializing, share your reading adventures or just keep exploring the pages Stay for lunch, and who knows? You might just find your next favorite book over a pizza. NB: If you plan to go for lunch, please consider bringing cash, as some restaurants only accept card payments after a certain amount.

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

**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.
