Join our ASL Brunch on Sundays in Greenbelt! All ASL users and learners are welcome. Brunches are alternately held at two restaurants in Greenbelt, both in the same town plaza. ODD WEEKS: 1st, 3rd, and 5th Sundays, we meet at Cedars of Lebanon, 103 Centerway. EVEN WEEKS: 2nd and 4th Sundays, we meet at New Deal Café,113 Centerway. We are the Greenbelt ASL Community, a group of both Deaf and hearing people who hang out, chat about everyday goings on, trade stories, get to know each other better, and of course, enjoy food together. Many members use ASL as their primary language, several are interpreters or other fluent ASL users, while others are ASL learners who wish to improve their skills while making new friends. Before or after brunch, you can visit the farmer's market and small coop grocery store in the plaza. Please RSVP so we can contact you via email if needed. Our group is on Facebook as Greenbelt ASL Community. Some long-time group members don't mark their attendance here, so feel free to stop by even if you don't see others who have RSVP'd on Meet-up.

DC Code and Coffee is an inclusive, informal co-working session. It's community-led and community-run by devs, for devs. People of all skill levels attend. Whether you’re dev-curious, aspiring, or a professional developer, we’d love to have you! Come chat or learn to code on a Sunday afternoon with coffee and cool-inclusive people. Bring your laptop! We typically meet every month on the weekend. **Join our online community!** For all things Tech in DC and to get latest updates and tech events from the DMV area, join the [DCTech Slack](https://dctech.chat/). All DC Code & Coffee announcements are in the #dccodecoffee channel **How it works** Near the beginning of the event, we do an introduction circle. You say your name, what you can help others with, and what you would like help with. You can also share job opportunities. After the introduction circle, everything is self-organized.

**Advance ticket sales have ended but plenty of additional tickets remain available at the door.** [Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The History of Plastic Surgery,”** with Dr. Wendy Chen, plastic, reconstructive, and hand surgeon and assistant professor at the Johns Hopkins School of Medicine. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-plastic-surgery](https://events.ticketleap.com/tickets/profsandpints/nv-plastic-surgery) .] Most people misunderstand plastic surgery as vain and aesthetic, but the origins of this fascinating specialty are much deeper than that. Come gain a rich understanding of the roots, medical impact, and current wide reach of a life-altering medical specialty with Dr. Wendy Chen, a leading educator on plastic and reconstructive surgery who has won awards for her work in clinical, basic science and education research. She’ll talk about how reconstructive surgery has been around for thousands of years, with evidence of it having been practiced in ancient Egypt and India, and has made advancements in the course of major wars. Those who practice it have been innovators in medicine, playing a major role in breakthroughs and winning the Nobel prize for kidney transplantation. The need for plastic and reconstructive surgery has stemmed largely from how much our appearance influences how we navigate our worlds and how others regard us. There was a time, in fact, when people in American prisons were offered plastic surgery as an intervention against recidivism. Yet reconstructive surgery also has faced opposition, such as religious bans on its practice stemming from the belief that physical differences are a manifestation of spiritual sin. Fast forward to now when plastic surgeons treat patients of every age for every kind of ailment, from congenital differences to trauma to cancer. Yes, some plastic and reconstructive surgery is to help people conform to tabloid- and social media-driven narratives of what defines beauty, but the field involves a lot more than injecting Botox and shaping buttocks. ( Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

When a team of Starfinders happen upon a civilian starship under attack by the Corpse Fleet in the Diaspora, it’s up to them to heroically drive off the undead attackers, board the starship, and rescue any survivors.

*Sometimes what keeps you stuck is not yours alone to carry.* In a **Systemic or Family Constellation workshop**, your inner world is brought out of abstraction and into living form. Instead of staying caught in cycles of overthinking, your challenge is mapped into physical space, revealing the hidden relationships, forces, and emotional patterns shaping your experience. As representatives step into different parts of your system, unconscious material begins to speak through sensation, posture, emotion, and impulse. What emerges is not merely insight but a direct encounter with the deeper structure beneath the issue. This work often reveals **hidden loyalties, interrupted bonds, inherited patterns, and unseen dynamics** that the mind alone can’t always access. By working through image, body, and energetic field, Family Constellation reaches layers of the psyche beyond words, creating shifts that can feel profoundly immediate. But this isn’t only about uncovering pain. It’s about reconnecting with what has always been within you: **strength, belonging, dignity, resilience, and ancestral support.** *If you’re ready for clarity, healing, and a new way forward, this work can open the door.* ✨ 💫 **Must register online FEE: $65** **Learn more and register** [here!](https://www.tealcenter.com/classes-and-events/)

This class is a perfect stepping stone from our flagship My Body Don't Bend That Way classes to traditional Vinyasa and Flow classes. The pace is slow allowing for plenty of time to get a feel for the postures and the proper alignment and modifications for your body. But don't let the slow word fool you! By slowing things down, even advanced practitioners can be challenged to build greater strength. **Please reserve your spot at www.piesfitnessyoga.com.** The session is offered InStudio and OnLine. The Zoom link for the OnLine session will be emailed 15 minutes before class starts to those who are registered at www.piesfitnessyoga.com. **Sign up for sessions must be made at least 2 hours prior to class.** The address is 1322 Prince St. Alexandria, VA 22314. Our entrance is located on the side of the building, parallel to West St. **Street parking is available and additional parking is located at Shiloh Baptist church, spaces 36,37,38,39.** The church is located across the street from the studio, on the corner of Duke St. and West St.

**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 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? 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

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?

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.
