📅 **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.

**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.

Described by the 'Scotsman' (top newspaper in the UK) as 'unexpected, clever, ridiculous but great stuff, crystal ball and all', this interactive comedy has left audiences worldwide laughing and wondering what just happened. Some say it's life-changing, others call it pure nonsense-but no one escapes without a few laughs, some spirit summoning and answers you probably didn't want. **Sold out run in Edinburgh Fringe Festival 2025** Reserve your seat for just €2, and at the end of the show, you decide what it was worth (suggested contribution: €10-15).

Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/cbus-hug-2026/

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
