Internet of Things (IOT)

​This gathering brings together women working in or curious about Bitcoin. We'll share real experiences, career paths, and lessons learned. The focus will be on how women contribute to building, securing, and supporting Bitcoin, from technical roles to adjacent fields. If you're already in tech or just starting to explore, join us to learn, connect, and discover what's possible. **👉 Please RSVP on Luma:** [https://luma.com/kn3txa1n](https://luma.com/kn3txa1n) Panelists will speak candidly about navigating the industry, building a career in emerging tech, and what it's really like to work in Bitcoin-focused organizations. The discussion aims to be approachable and insightful, giving women a clear, real-world view of opportunities, challenges, and growth in Bitcoin and related technologies. ​***Please respect the Bitcoin-only focus: We do not discuss, promote, or entertain conversations about altcoins, tokens, ICOs, NFTs, memecoins, or any other cryptocurrency projects.

Join us for Python Project Night! Project Nights are informal gatherings where attendees can bring their own projects and work together (or just next to each other). We'll have at least one experienced Python web developer on hand to help less experienced people with their projects. We host these project nights each month in addition to our normal talk meetups. Agenda • 6:30-7:00pm - Arrive, eat and catch up (thank Chief (http://agencychief.com/) for the food!) • 7:00pm-8:45pm - Coworking What could you do at project night, you ask? • Work on your own side projects with other people doing the same • Get help learning Python (or Django or Flask) from more experienced developers. (Or, help mentor other attendees if you're already a whiz) • Ask for a code review for a project you've been working on by yourself • Talk through a particular problem with someone who has solved it before • Just hang out and have some cool conversations! We are cross-listing this event with DC Python, so please RSVP to only one so we can get an accurate headcount.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Our Bodies, Our Minds,”** an exploration of the relationship between our biology and our thought processes, with Justin Brooks, M.D., associate professor of computer science and electrical engineering at University of Maryland, Baltimore County and scholar of computational psychophysiology. [Advance tickets: $13.50 plus sales tax and processing fees. Available at h[ttps://www.ticketleap.events/tickets/profsandpints/dc-bodies-minds](ttps://www.ticketleap.events/tickets/profsandpints/dc-bodies-minds) .] For millennia, humans have wondered how mind and body are connected. Are our thoughts just the electrical murmurs of nerve cells, or is there something more? Are they the result of millions of years of evolution? Explore the mind-body problem through the lens of measurable physiology with Dr. Justin Brooks, a physician-scientist whose research focuses on using mobile and wearable technologies to understand, predict, and influence human behavior and health. He’ll describe how millions of years of evolution shaped the way our minds and bodies speak to each other, with our nervous system being the product of countless adaptations that shape how we react, think, and survive. Reflexes hidden in our physiology, attention, and mental effort reveal a “biotype,” a stable but adaptable signature of how we process the world. The problem is that reflexes honed by a prehistoric world of predators and scarcity now must navigate the strange demands of a modern society. Rather than mirroring who we truly are, our reflexes often are just echoes of ancient survival needs. As a result, many of us live slightly out of sync with our own biology. We think faster than we feel, ignore our body’s quiet warnings, and misread the signals from our bodies that guide balance and well-being. Breakdowns in the conversation between mind and body cause stress to accumulate, performance to falters, and health to erode. In a talk that blends neuroscience, physiology, and philosophy, Dr. Brooks will discuss how our specific biotypes might hold clues for realigning our ancient wiring with the pace of contemporary life to avoid the pitfalls of burnout, chronic stress, and mental fatigue. He’ll explore how measuring the body can illuminate the mind and how both can be brought back into harmony for the world we live in now. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Magpie (Greg Artzner & Terry Leonino) will be joined by special guests: local favorite Charlie Pilzer (bass) and Pennsylvania guitarist Rolly Brown Saturday, February 21, 2026 At Seekers Church, 276 Carroll Street, NW, Washington, DC 20012 Register at [https://fsgw.org/event-6513844](https://fsgw.org/event-6513844?fbclid=IwZXh0bgNhZW0CMTAAYnJpZBExVzFsMlFrWUNiWGxHVXp2OHNydGMGYXBwX2lkEDIyMjAzOTE3ODgyMDA4OTIAAR4Lcbv0sJbWjIW0yPra48Fw8y7yGpwoQsXYsVd0wqx2SPurKQfmZ8E91wvZ5g_aem_N9L5lN0ZeAtQhcSocJErIQ) Or for the online version at [https://fsgw.org/event-6548489](https://fsgw.org/event-6548489) When we learned that longtime DC folk favorite Magpie would no longer be performing at Milllenium Stage, we were delighted to welcome them to our FSGW concert series. In the finest American tradition of folk songs, Magpie is planning an evening concert of hard-hitting songs of protest featuring the songs of Phil Ochs, but will interweave them with songs written for the current times by Terry & Greg themselves, as well a song or two from other fellow songwriters. It will be a night of songs that express outrage, sorrow, humor, hope, and determination. This concert will be preceded by a brief membership meeting starting at 7:45 pm, followed immediately by the concert at 8 pm. Doors open at 7:30pm. Admission is FREE to members Non-members: $25, but may join (or rejoin) at the concert and get the member price We expect this concert to sell out, so preregistration is strongly recommended, including for members Questions?

Friday night Greenbelt International Folk Dancing has gone "virtual". As we all practice good social distancing, many in our folk dance community are feeling the absence of our usually scheduled local dances. In response, please join us for the Greenbelt Virtual Folk Dance Session. Let’s keep dancing! • Connect and dance in our own homes • Watch hosts leading familiar dances • See each other; listen and dance to our favorites How: We will be using the ZOOM video conferencing app to share music and live videos of the leaders and each other. This can be used on a desktop, laptop, or smartphone. What to Expect: Your hosts are Linda Mansdorf, Vita Hollander, Ben Hole, and John Robinson. Collectively they will play 25-30 dances, which should approximate the number of dances normally done on a Friday night in-person event. The hosts will do a quick teaching or demonstration of the steps to some of the dances that may be less familiar to you or just as a refresher, but the session is not designed as a workshop, so the majority of the evening will be spent playing dances that many of us already know and love to do. How To Join Us: Each week we will send an email with the Zoom Meeting link ID. Make sure John Robinson knows you would like to receive this email with the link.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
