Join us for a 7.5 mile casual ride from King Farm to Rockville Town Square and back. Learn some of the useful cut-throughs and bike lanes that can help you get to and from downtown Rockville! Our route will be on neighborhood streets, multi-use paths, and bike lanes. READ THE FINE PRINT, PLEASE: • Bicycling involves inherent risks and requires that participants be in proper physical condition. When you RSVP "yes" to a Bike Rockville event, that RSVP is your digital signature attesting that you have read, understood, and agreed to the group's Liability Waiver and Release, located here: [https://drive.google.com/file/d/1BocKiaMJwba62c7b583CoOxIYamFiaWN/view?usp=sharing](https://drive.google.com/file/d/1BocKiaMJwba62c7b583CoOxIYamFiaWN/view?usp=sharing) • HELMETS ARE REQUIRED for all riders on every ride. • We strongly recommend you bring a water bottle, spare tube, cell phone, ID card, and cash or credit card for emergencies. • Rain at start cancels the ride; Wet pavement does not.

A small team of AWS Solutions Architects not traditional software engineers, built AIRE Traffic Control (ATC), a production agentic AI platform now serving thousands of builders. We used AI at every stage: spec-driven development, AI-generated code, automated testing, and agentic workflows. In this talk, we'll share the real story, the architecture, the failures, the breakthroughs, and what we learned about driving adoption from 32% to 92% in 10 weeks. You'll walk away with practical patterns for building multi-agent systems, using AI-DLC methodology, and empowering non-traditional dev teams to ship production-grade applications.

**The Neural Revolution Is Happening Right Now — Are You Plugged In?** Imagine typing with your thoughts. Steering a robotic limb with a neural signal. Lifting depression by stimulating a single brain circuit. Loading a skill straight into memory. This isn't science fiction. It's happening in labs, clinics, and startups around the world — and the DC region, home to NIH, the BRAIN Initiative, and DARPA's neural-interface programs, is one of the places it's being funded and built. **This Event Is for You If…** * ✅ You're a **technologist** curious about the computing paradigm beyond screens and keyboards * ✅ You work in **healthcare** and want to see how neural interfaces will reshape patient care * ✅ You're an **entrepreneur** hunting the next real opportunity in deep tech * ✅ You're a **researcher** looking to plug into the broader BCI ecosystem * ✅ You're simply **fascinated** by where neuroscience and technology collide * ✅ You **missed our last meetup** and want to reconnect with the community **Why That List Makes Us Unique in DC** Read it again. A technologist, a clinician, a founder, a researcher, and the merely curious — in the same room, on the same afternoon. That mix is the whole point, and it's what no other event in the region offers. Neuroscience conferences are built for neuroscientists. AI meetups are built for engineers. Healthcare summits are built for clinicians. Each one serves a single silo. Brain computing doesn't live in any one of those silos — it lives in the overlap. So we built the one community in DC dedicated to that overlap: a place where the person decoding neural signals can talk to the person who'll commercialize the device, who can talk to the clinician who'll put it in front of a patient. **What You'll Walk Away With** This isn't just another tech meetup. Because of who's in the room, you get: * **Frontline insight** from people actively decoding neural signals * **Direct access** to the scientists, engineers, and founders pushing BCI forward — not a panel behind a rope line * **Hands-on work** with real neural data and BCI systems * **Career connections** in one of the fastest-growing fields in tech * **First looks** at breakthrough research before it reaches mainstream media **The Stakes Are Real** We're at an inflection point. The next decade decides whether brain-computer interfaces *expand* human potential or *deepen* inequality — whether they're built in the open or behind closed doors, whether the benefits are shared or hoarded. Your voice, your expertise, your perspective shapes which future we get. **Join the Minds Shaping Tomorrow** This is your entry point into the neural-interface revolution — your chance to stand alongside the researchers reading neural code, the engineers building the interfaces, the clinicians treating patients, and the founders bringing it all to market. **Saturday, June 13 · 12:00–3:00 PM** isn't just a meetup. It's the one place in DC where all of those people come together around brain computing. **Come curious. Leave connected. Return transformed.** Because the future of human-computer interaction isn't happening *to* you — it's happening *with* you.

The way organizations build teams and the way professionals build careers is changing. Fractional, part-time, and project-based work is no longer a stopgap. It's becoming a deliberate strategy on both sides of the work equation; the "Portfolio Career" of the future is happening now. In this session, Stephanie Ranno draws on her work connecting experienced professionals with employers who are rethinking how they access talent. Whether you're a content strategist navigating a tough market and piecing together flexible engagements or an organization weighing whether a fractional hire could move the needle for a specific project, this session offers practical perspectives for both. We'll explore what's driving the shift toward flexible work arrangements, how to position yourself or structure your team to make the most of it, and what it actually takes to make fractional and part-time roles work well for everyone involved. **About Stephanie** Stephanie brings more than 20 years of experience in staffing and recruiting, helping organizations of all sizes and in all industries build high-performing teams. She has worked with clients in financial services, associations and nonprofits, government consulting, and professional services to connect them with exceptional talent.

**The next GeoDC will be held on Wednesday, June 10 from 6-9pm at Sudhouse DC (1340 U St NW, Washington, DC 20009) with the program starting at 7pm.** * Join us early from 6-7pm to grow your network, socialize and grab drinks and appetizers. * Throughout the evening, we'll be sharing job announcements and details of other GIS/Geo upcoming events we're tracking. * We look forward to seeing you on the 10th! **Our Program will feature these presentations:** **The Secret History of the Blue Dot - William H. Tewelow, GISP (GPS World)** This presentation takes the audience from an iconic movie scene they recognize but never understood, through the hidden origins of GPS, and returns them to the blue dot in their own hand, seeing it for the very first time. There is a blue dot on your phone right now. It knows where you are to within a few feet. You have never questioned it. You have never wondered where it came from. You should. Its origins are classified. Its lineage runs through the Cold War, nuclear submarines, and a doctrine built on the promise of mutual annihilation. The technology that tells you where to turn was designed for something else entirely. The technology did not change. Only the purpose did. **GEOINT Symposium's Golden Ticket Program - Katie Weintraub (ESRI)** This is a firsthand account of USGIF's GEOINT Symposium Golden Ticket — a program built for early-career professionals who want to level up their careers. Participants get free admission to GEOINT Symposium, mentorship opportunities, a network of fellow Golden Ticket alumni, and a cohort of peers to grow alongside. This talk breaks it all down fast — what it is and why it's a stellar experience for young professionals breaking into or already working in the geospatial intelligence realm. *->If you’d like to present or sponsor a future GeoDC Meetup, please complete this [form](https://forms.gle/QbAXPfrDnX12GGaS8).*

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
