Mainframe Computing

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.

**Agenda:** • 5:00 PM - Doors Open (in-person attendees). • 5:30 PM - **Deep Dive into Claude Code** • 6:30 PM - Networking • 7:00 PM - Doors Close **Talk Overview:** **Deep Dive into Claude Code** Ever wondered what happens under the hood when Claude Code runs your next Android task? This talk dives into the internals of Anthropic's AI coding agent — its bootstrap pipeline and agent loop. You'll see how fork agents share prompt-cache prefixes to cut input token costs and how four-layer context compression keeps long conversations from exhausting the window. You'll leave with a mental model of how this production AI agent actually works. Whether you're building custom MCP integrations, orchestrating multi-agent tasks, or just trying to get more from the tool you use every day, you'll have a toolkit of patterns to apply to your own Android workflows. **Speaker**: Mohit Sarveiya **Speaker Bio:** Staff Android Engineer AirBnb & Google Developer Expert **How to find us:** 1680 Capital One Drive, McLean, VA 22102 We'll be located in C2 **100 D/E**.

**Alert! New Location**: We will be trying a new location for this game night, Punch Bowl Social in Arlington. We will post our exact location once we get settled. From BGG: ***Bruxelles 1893*** is a worker placement game with elements of bidding and majority control. Each player is an architect of the late 19th century and is trying to achieve, through various actions, an architectural work in the Art Nouveau style. The most successful building yields the most points. Each player can also create works of art to increase their score. We have 2 copies, and the game accommodates up to 5 players. If you can bring a copy, let us know in the comments. If we don't get any more copies and there are more than 10 RSVP's, we will add a table of ***Bruxelles 1897***, a card game based on *Bruxelles 1893*.

Title: An Easy Intro to Feynman's QED, Part 3: Electron-Photon Interactions Date: June 13 2026 Noon - 14:00 EDT Summary: In his second QED talk on May 16, Terry discussed how Nobel Laureate Richard Feynman kept Einstein’s idea of a photon as a particle, but replaced the photon’s singular path through space and time with an integral of all paths the photon could have taken. In this final talk, Terry adds Feynman’s critical concept of how photons interact with another incredibly common particle, the electron. He shows the resulting model, called QED, describes not only most everyday phenomena, but also issues such as why antimatter can be interpreted as ordinary matter traveling backward in time. Speaker: Terry Bollinger is a computer scientist with BS, MS, and Professional Degrees from the Missouri University of Science and Technology.

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
