**Fabric Direct Lake: When and Why You Should Consider Using It** Direct Lake in Microsoft Fabric allows Power BI to query data directly from OneLake using Delta tables, delivering fast performance without the need for data imports\refreshes. In this session we introduce Direct Lake and how it fits into the Fabric analytics architecture. We’ll look at scenarios where it works well, particularly for simplifying data pipelines and reducing data duplication. The talk will also highlight key advantages such as performance and architectural simplicity. We conclude by looing at some of the limitations and trade-offs to consider when deciding whether Direct Lake is the right approach for your solution. **Logistics:** * Format: Hybrid (remotely and in person) * In Person: Entelect (Boardroom TBC) * Remote: Now on Teams [here](https://teams.microsoft.com/l/meetup-join/19%3ameeting_NDBhN2FmYzEtMTNmMi00ZTdhLTkzNWQtNzJiZDZmNjMyNDAw%40thread.v2/0?context=%7b%22Tid%22%3a%22e3183c89-78ae-43e0-b8a3-3eb012e5d9ea%22%2c%22Oid%22%3a%22d1186f7a-a0f7-4629-a372-0dcbfd79cf85%22%7d) (Meeting ID: 375 463 344 65, Passcode: 26Kz3t9X) * As usual, pizza and refreshments will be served for those attending in person.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. 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.

**New Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 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)

**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.
