SAM BASU IN-PERSON; NOTE: THIS IS THU, NOT TUE AS NORMAL Code is cheap, but software is expensive. Modern AI is a big opportunity to streamline and automate developer workflows for better productivity. There are some challenges though – AI Models often lack knowledge and AI Agents need expertise/guidance to reliably pull off complex workflows. Context is everything for modern AI and you can bring it. Model Context Protocol (MCP) aims to provide a standardized way to connect AI Agents to different data sources, tools and non-public information - the point is to provide deeply contextual information/expertise to AI. Skills are higher-level behaviors and instructional guardrails, that define how and when AI Agents should leverage tools to accomplish something meaningful. Subagents in AI are specialized, task-focused agents designed to handle specific, well-defined tasks within a larger AI system. In terms of the food industry: AI Agent = Chef 👨‍🍳👩‍🍳 MCP Tools = Raw Ingredients 🥔 🥩 Skills = Recipe Cards 📝 📇 SubAgents = Sous Chef 🔪 🍳 Loops = Door Watcher 💂👀 Developer = Restaurant Owner 👑. So, what should developers use to bring context and guardrails to make AI work their way? Well, it depends and sometimes, the answer might be whatever combination makes developers most productive. With official SDKs and well-thought-out guidance, it is a breeze to work with MCPs, Skills or SubAgents. Developers could bring their own data, APIs, services, coding patterns and structured guidance to make AI Agents work their way. And AI Agentic workflows work the same way in IDEs or Terminals, paving the way autonomous ways of getting work done with AI. With contextual expertise to light up unique coding workflows, AI Agents can make developers ultra productive – upwards and onwards.

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
