What if the best product requirement was a working prototype? Amazon built an empire on one principle: start with the customer and work backwards. Identify the durable need. Resist building until you know what you're solving - and for whom. Vibe coding doesn't abandon that discipline. It supercharges it. Join us for an in-depth discussion on how natural language becomes structured specs, specs become architecture, and architecture becomes working software - in real time, in the room, on your machine. Whether you're validating a product idea or accelerating a team's delivery, this is where the “Working Backwards” mindset meets the AI-native development stack. **Featured speaker:** * [AJ Bubb](https://www.linkedin.com/in/ajbubb/), Innovation Strategist and AWS veteran - for a hands-on session exploring Spec-Driven Development with AWS Kiro. \~ "*We're not just talking about it. We're building with it*!" **Location:** AWS Skills Center, 1550-G Crystal Dr, Arlington, VA 22202 **Drinks and Networking After:** Tacombi, 1550 Crystal Dr, Arlington, VA 22202 **Description:** Join us at AI Innovators Network for our upcoming meetup in the Mosaic, which is dedicated to exploring the latest trends in Artificial Intelligence.

Connect with like-minded individuals from DC, Northern Virginia, and Maryland as we dive deep into the opportunities and challenges of integrating AI. Don't miss this opportunity to be part of the conversation driving innovation and progress in Artificial Intelligence.

Bonsoir à tous! Venez nombreux pour causer autour d'un repas ou d'un verre chez La Madeleine. On n'a que deux règles: (1) qu'on y parle exclusivement le français et (2) qu'on achète quelque chose à boire ou à manger (c'est La Madeleine qui le demande). Merci et à bientôt!

Celebrate Earth Day with Sierra Club Potomac Region Outings on a hike along the Potomac River at the Chesapeake and Ohio Canal National Historical Park in scenic Frederick County, Maryland. Once proposed as a paved asphalt 185 long parkway, the beautiful and historic C&O Canal was protected in its natural state by Supreme Court Justice William Douglas and others who were motivated by the same community spirit that created Earth Day on April 22, 1970. Our Sierra Club PRO hike will start at Point of Rocks and go upstream along the Potomac River to our turnaround point at Catoctin Creek Aqueduct. Hiking distance: 7 miles over the totally flat C&O Canal towpath, which is also part of the Potomac Heritage National Scenic Trail. Meet at 10:30AM at the west end of the Point of Rocks Train Station Parking Lot near the Point of Rocks Community Commons Park. Bring a daypack, hiking boots, lunch, trail snacks, and two quarts of water. Leader: Glenn Gillis 571-217-4477 and Gary Kosciusko 703-946-8111.

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!

Kim Richey is one of my top favorite musical artists. I have been a fan of her music since the late 90s. She is also a sweetheart and a pleasure to chat with. I have seen Kim Richey with two musicians (herself included), three musicians and with a full band in Nashville and I am always impressed on how terrific the concerts are. She is scheduled to play at Jammin’ Java on May 10th. The ticket link is below. Here are a bunch of songs I selected from her first three CDs (my favorite CDs of hers. Every track on every CD is a gem). She draws a lot of her concert songs from those CDs. [https://www.youtube.com/watch?v=7MjBb_2WOys&list=PLG-Pcqm-1YXhs1rt8HO_A0jSlnTggUrUP](https://www.youtube.com/watch?v=7MjBb_2WOys&list=PLG-Pcqm-1YXhs1rt8HO_A0jSlnTggUrUP) The first time I saw her was at Jammin’ Java (which is a nice little venue, btw). We chatted after the show. It was like chatting with an old friend. I asked her about playing with a full band. She told me that she will have a full band in Nashville. I gave it a bit of thought and told her that I have family in Clarksville (about an hour from Nashville). As we parted company, I was about 20 feet away from Kim when she shouted out to me, “Hey Felice!” (I introduced myself to her with my birth name). “I’ll see you in Nashville!”. I looked at her and said something like, “I guess I \*have\* to go now”. 😊 And I did. My second Kim Richey concert and that was a blast, and I got to see a bit of Nashville. I also met the multi-talented, Sav (“as in Savage”, she said to me) and I learned of her wonderful band, The Accidentals. I live for serendipity. Jammin’ Java is a small venue. You select your seat from a chart. Food and drinks are served. They have delicious pizza! My seat is at Table F. Right now, there are several seats available at my table. GA seats are not at tables. The elevated section is a real nice view with a table, if you prefer. To select a seat, click in the graphic with the Stage and Tables.

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
