Join us for another session of our study group as we continue our coverage of the book Domain-Specific Small Language Models. In this session, we will attempt to cover Chapters 9 on "Advanced Quantization Techniques" and Chapter 10, on "Profiling Insights" to understand resource utilization by an SLM. This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to continue to learn together. If you plan to work with the code on your own laptop during the session, try and download the code from here https://github.com/virtualramblas/Domain-Specific-Small-Language-Models ahead of time.

**NOTE: most of the regulars no longer RSVP to the Meetup. You'll usually find at least a half dozen of us playing chess, regardless of how many attendees are listed. Come on by!** The Fairfax Chess Club meets on Monday nights at Mackenzies', a restaurant in downtown Fairfax City. People start showing up around 6pm and stay until whenever. All ages and chess levels are welcome. The address: 3950 University Dr STE 210, Fairfax, VA 22030 There is free parking available in a free garage behind the restaurant. There are 3 or 4 chess boards available for general use at the restaurant, but bring your own if you have one. Please try to purchase something to eat or drink at Mackenzie's (it can be small), like a soft drink, beer, or side of fries. We have to support our venue! Thanks! Isaac

Curl up with a good book and a hot cup of your poison of choice. Maybe start a book club to talk about your favs and read together.

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.

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.

The next NoVABeerSec event - "Informal Gathering of Security Minds Over Beer" will be Wednesday, April 29th, 5:30PM til 7:30ish at Aslin Beer Company - Herndon Taproom (767 Elden St., Herndon VA 20170). **Venue for April:** Aslin Beer Company (https://www.aslinbeer.com) - Aslin Beer Co. was founded in 2015 by Andrew Kelley and Kai Leszkowicz. The name, Aslin, comes from the family that connected Andrew and Kai through marriage; they each married a daughter from the Aslin Family. Andrew’s professional background was in finance and consulting, while Kai worked in public service. They bonded over a shared interest of craft beer and home-brewing, which eventually lead to the idea that “We can do this too.” **Additional Info:** We are an inclusive group, so if we missed anyone please let us know or if you want to bring your significant other/spouse please do. We do know there are folks that have changed roles since we last met so please also let us know if we need to add new contact info for people. Have a great week and see you later this month! Cheers, Rinaldi Rampen & Mike McCabe of @NoVABeerSec
