We’re excited to continue building AI in Practice with our monthly social! 🎉 Each month, we’ll host an informal happy hour and dinner at Upside on Moore in Rosslyn. Come join fellow AI builders, professionals, and curious minds for a relaxed evening of conversation, connection, and community. Whether you’re working on AI systems, advising on responsible adoption, or just interested in how AI is shaping law, compliance, finance, healthcare, defense, software, mission-driven organizations, or public service — this is a chance to meet like-minded people and help shape what this community becomes. 🍸 Drinks and food are available for purchase at the venue. 🤝 No formal agenda — just introductions, networking, and sharing what excites us about AI in practice. We’re so grateful for the early enthusiasm, and we look forward to seeing you each month as this community grows! **Date, Time & Location** 5:30 PM – 7:30 PM Tuesday 14 April 2026 Upside on Moore 1831 Moore Street Arlington, VA 22209

​This meetup is for anyone building with OpenClaw (& Claude Code) or experimenting with other AI tools to create agents that can act and make decisions on their own. If you haven’t tried these yet, come hang out, ask questions, and see what others are building. We’ll trade notes, troubleshoot setups, and explore what it takes to run these systems openly on the web instead of inside closed platforms. Bring your laptop, grab some power, and jump into a night that feels part LAN party, part live build session, where people test ideas and show what their agents can actually do. 👉 [RSVP on LUMA](https://luma.com/53dx7no1) We’ll also have some fun by running a live test to see if a few of our agents can send Bitcoin back and forth and talk about why that’s a meaningful step for autonomous AI. It’s a chance to connect the dots between open AI tools, Bitcoin, and the wider goal of creating technology that no one can turn off. 👉 [RSVP on LUMA](https://luma.com/53dx7no1)

The AWS Sustainability Hackathon is a 2-hour micro hackathon where students will vibe code and build an app focused on sustainability using AWS in some capacity.

Winners will receive merch and a $50 Amazon gift card each, and free food will be provided.

We are honored to host Jaime Echt from The Crafter's Workshop for our annual Creative Minds Summit. Whether you’re new to Stencil Butters® or a longtime fan, this class is going to bring your Mixed-Media/Art Journaling game up a notch. You’re going to start by making a color swatch ring of all your favorite colors (and there are over 40 colors to choose from.) This’ll give you a chance to see how colors interact with water and other modifiers. Plus it’ll be a great reference tool to take home with you. From there you’ll create one or more frameable pieces of art. Jaime will walk you through technique after technique, from mark-making to stenciling, from dry brush to wet palette knife, and everything in between. You’ll leave with the swatch ring and at least one finished piece. Feel free to bring your art journal to work in. Learn more about this class, your student supply kit fee & list via Artistic Artifacts’ secure online website: [https://artisticartifacts.com/products/cms-color-mapping-abstract-art-with-jaime-echt](https://artisticartifacts.com/products/cms-color-mapping-abstract-art-with-jaime-echt) \*\*\* Due to the size or other requirements of the class or concurrent scheduling, some classes are in our second-floor space: access is via stairs only.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

Curious about “vibe coding” but not sure what it actually means? This beginner-friendly talk is about how people are using AI to build websites, apps, automations, and small software projects by describing what they want in plain English. We’ll cover what vibe coding is, what AI is good at, where it falls short, and how to actually use it without getting lost. The goal is not to hype AI as magic — it’s to show how to use it as a practical tool. This session is designed for beginners, curious builders, non-programmers, and developers who want a clearer picture of how to build with AI today. Topics include: * What “vibe coding” means * What AI can help you build * Where AI is useful and where it is unreliable * A simple workflow for building with AI * Prompting tips for better results * Common beginner mistakes to avoid If you’ve ever thought, “I have an idea, but I don’t know how to build it,” this talk is for you. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee.
