NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it! Hope to see you there! **Location** Our hosts are the Fairfax City Economic Development Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1) Conference Room A- Large, Floor 1 This is a new venue for us, so give us some time to get more details about it.

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.

Socrates Café meets on the first Saturday of each month. Though this may be considered a "philosophical" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things. Prior to each meeting we vote online for the questions we will discuss. That way, we will have enough time to ruminate on them and have more in-depth conversations. If you RSVP to a meeting, you may post your question in the event comments section below. I'll send out a survey for voting a few days prior to the meetup. We discuss two questions each night. So you will get to cast two votes in the survey. When we meet, we break into smaller groups of five to seven to discuss the top two vote-getters. Each group discusses one question for around 45-50 minutes, and we then take a short break. After reconvening, each group moves on to its second question. Hope to see you there! -Brian

Come and meet with fellow Apple AND Android developers in the DC Area, enjoy some food, networking, and a great tech talk! 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.
