**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.

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** [https://youtube.com/live/fD2cYeKp_UU?feature=share](https://youtube.com/live/fD2cYeKp_UU?feature=share)

**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)

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!

**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.
