**Come Sing With the Fairfax Jubil-Aires!** Do you enjoy singing along to your favorite songs? Curious what it’s like to sing rich four-part harmony with a friendly group? Come visit the weekly rehearsal of the Fairfax Jubil-Aires and see what barbershop singing is all about! The Fairfax Jubil-Aires are a welcoming mixed a cappella chorus that performs classic and contemporary barbershop harmony. Our members come from all kinds of musical backgrounds—some have years of experience, while others simply love to sing. What we all share is a passion for music, laughter, and community. Visitors are always welcome at our weekly rehearsals. You can sit back and observe, or jump right in and sing with us—no pressure either way. You don’t need to read music, and there’s no audition required just to visit. We rehearse **Wednesday evenings at 7:00 PM in Fairfax**, and we’d love to have you stop by and check it out.

PLEASE INDICATE IF YOU WILL BE ATTENDING IN PERSON OR OVER ZOOM. **Agenda (NOTE THE LATER START TIME):** • 6:00 PM - Doors Open (in-person attendees). **Don't forget your ID!** • 6:30 PM - Welcome (in-person and Zoom attendees) • 6:35 PM - **First Talk: From Shared Logic to Shared Pixels: A KMP & CMP Deep Dive** (Live from DC) • 7:05 PM - Community Announcements • 7:15 PM - **Second Talk: Swift on Android** (Virtually from NYC) • 7:45 PM - Networking **First Talk Description:** • From Shared Logic to Shared Pixels: A KMP & CMP Deep Dive Clinton Teegarden Explore the complete lifecycle of Kotlin and Compose Multiplatform, tracing the journey from compiler mechanics down to the practical day-to-day developer experience. By building a Flappy Bird-style game, we'll unpack how shared UI rendering actually works while navigating the realities of iOS interoperability and common architectural gotchas. You'll leave with a clear roadmap for seamlessly translating shared business logic into performant, cross-platform pixels. Clinton is a Distinguished Engineer at Capital One with a focus on Mobile and AI core platforms **Second Talk Description:** • Swift on Android Marc Prud'hommeaux The release of Swift 6.3 features official support for the Android platform. This is the culmination of over 10 years of effort to bring the Swift language to Android, first through a series of independent and uncoordinated projects and then eventually coalescing into an official Android Workgroup under the umbrella of the Swift project. The result is the Swift SDK for Android, a cross-compilation Swift SDK that can be used on macOS and Linux to compile Swift code into the various Android architectures as a native library. But what can you actually do with Swift on Android? Far from being limited to just libraries for sharing business logic between Android and iOS, you can, in fact, use it to build and distribute entire apps. This talk will discuss the various ways in which the Swift SDK for Android can be used to create applications, from the lowest-level manual native interaction with the Android NDK and SDK, to synthesizing Java bindings generated with the nascent swift-java project, all the way up to creating full Jetpack Compose powered apps using [Skip.dev.](http://Skip.dev.) Swift is now a contender among the languages that can be used to build applications for both iOS and Android. While it is a newer entrant compared to the established players like Dart, JavaScript, and Kotlin, it features some distinct advantages that make it worth considering for your next app project. Marc Prud'hommeaux has been developing apps for iOS and Android since 2008, and was the author of the very first ebook reader for the iPhone: Stanza. He has worked in a variety of roles over the years, designing and building apps for giants like Amazon, Bose, and the New York Times. In 2022 he started [Skip.dev](http://Skip.dev) ([https://skip.dev](https://skip.dev/)) with the vision of bringing Swift and SwiftUI application development to Android, and is one of the founding members of the Swift Android Workgroup. He is also the founder of the non-profit App Fair Project ([https://appfair.org](https://appfair.org/)) and an advocate for software freedom.

Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. 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.

**Location**: Tysons-Pimmit Regional Library (Virginia) Conference Room A game development **Working Session** involves 3 key parts: 1. Tell people what you're going to do 2. Actually do stuff 3. Show people what you did That's what we'll be doing for this meeting. We'll briefly tell each other what we're going to do, then work on our projects, then at around 5:30 wrap up to show each other what we did and chat for a bit. You don't have to stay the whole time, so feel free to drop in and out as you have time. All game development skill levels welcome. Whether you're bringing a game you're trying to ship in a month, or you're just planning on following some tutorials or trying out a new tool to improve your skills, use this time to make progress. Working sessions also train you to think about the scope of your work: pick a chunk of work that you can complete in the time that we have. That way you can end the working session with a feeling of accomplishment! **What to bring**: Laptop, Charger, maybe a power strip if you have one handy, any other game development tools you need. Try to download any software you need before the working session. There is Wifi at this location, but it may be slow if you have to download any large files.
