Everyone’s prompting. Few people are judging. This talk shows how a playwright uses multiple LLMs and vibe coding to build a custom evaluation loop: a digital dramaturg that checks scenes against an outline like a living spec. If you design, build, or eval AI systems, you’ll leave with a new mental model for using LLMs as QA, not just content engines. **Featured speaker:** * [Soo-Jin Lee](https://www.linkedin.com/in/soo-jinlee/)\, Gen AI Conversation Designer \| Prompt Engineer \| LLM\, NLU\, NLP \| Human in the Loop \| Former Teacher \| Playwright **Location:** AWS Skills Center, 1550-G Crystal Dr, Arlington, VA 22202 **Drinks and Networking After:** --> Alamo Drafthouse, 1660 Crystal Dr, Arlington, VA 22202 (2nd Floor) **Description:** Join us at AI Innovators Network for our upcoming meetup in the Mosaic, which is dedicated to exploring the latest trends in Artificial Intelligence.

Covid Alert: We will start having classes again at Canal Park on Wednesdays and Saturdays. Please bring your own hand sanitizer, and mask are a must! We'll practice from a safe distance from each other; and progress from there. "DC Kali" is an official training group for FCS Kali. Our curriculum includes knifes, swords, stick-fighting, striking, and grappling; but we place a special emphasis on edged weapons. Please come out and learn some Kali. Our aim is to train hard, learn some sound defense strategies, and make friends along the way. Although FCS Kali is a combat-oriented systems that involves edged weapons, we provide a safe environment for learning w/o sacrificing realism in our training. We teach in small semi-private groups, allowing each individual student to progress as quickly as he or she can absorb the info being taught. Hope to see you all there. Mosi K. Jack, Esq.

Filipino Combat Systems(FCS) is an organization/system with members from around the world. FCS is based onTuhon Ray Dionaldo's over 35 years of practicing various FMA (Filipino Martial Arts) styles. He's combine elements of each, into one system that's efficient, fast, concise, and logical. FCS members have extremely diverse backgrounds, and Martial Arts systems.

Join DC Metro Crafts for a field trip. We'll be at Quill and Crumbs, the cafe at the Shakespeare Folger Library. The Shakespeare Folger Library is about 3 blocks from the Capitol South metro. Head up First as you get out of the station, pass the Library of Congress and the Capitol, turn right on East Capitol, and the Folger is on the right. The entrance is around the side, not through the front of the building. Head upstairs to the cafe and we'll be at the tables at the back. Bring your own cross stitch, knitting, crochet, or other portable craft.

Date : Feb 7 2026 13:00 - 15:00 EST Title: Symmetry, Topology, and Magnetoelectric Multiferroicity — Ferroelectric 'Tweezers' for Quantum Magnetism in Hexagonal Ferrites Abstract: The scalability of future quantum and spintronic hardware is currently facing a "physical wall": the challenges of excessive heat dissipation and environmental magnetic noise. To overcome these barriers, materials where magnetism can be controlled with high precision and minimal energy will be highly desirable. Magnetoelectric multiferroic hexagonal rare-earth ferrites (h-RFeO3, R: rare earth) have emerged as an important platform for this mission, offering a unique "playground" where symmetry and topology dictate functionality. In this talk, I will provide a comprehensive overview of research progress on these materials over the last decade. We will explore how a specific structural transition—trimerization—breaks symmetry to create a robust state known as improper ferroelectricity as well as weak ferromagnetism. The coupling between the ferroelectric and magnetic orders leads to a "ferroelectric tweezer" effect, where the material's ferroelectric domain spatially anchors and manipulates magnetic domains. Furthermore, we will address the "readout challenge": how to detect the diminutive magnetic moments inherent in these systems. I will show how the non-coplanar spin topology acts as a signal amplifier, enabling high-fidelity readout of magnetic states through spin-transport. By understanding the "solid science" of these complex oxides, we can define the roadmap for a new generation of stable, low-power topological electronics. Biography: Xiaoshan Xu is Susan J.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.

We will have lunch at Cap City Diner in Gahanna at 12:00 then walk over to the theater afterwards. The Movie Solo Mio starts at 1:20.It will be posted when tickets available to purchase probably the week before then we’ll post our seat number so we can all sit together 😎

**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** TBD **YouTube Link** TBA
