• What we'll do On https://blackecon101.podbean.com/ Thursdays at 6 pm. discussing the economy....

**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**.

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.

Hi Everyone! This will be the FINAL (yes, you read that right!) event for this meetup group, so let's go out with a bang! Come celebrate Pride month and the community we’ve built for the last 4 years. Early arrival is suggested! This event is for Black queers only (no cis men)! Please update your RSVP if you can no longer attend. Happy hour drink specials pictured below. You're welcome to bring outside food since this venue does not serve food. We may have some celebratory cake. See you there!

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.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time.

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
