AI coding tools are no longer just smart autocomplete. They can act like background teammates working in parallel. This working session will unfold in two parts. First, Lee will demonstrate how to orchestrate multiple AI agents simultaneously using GitHub Copilot. He will show how to isolate work across branches and coordinate independent tasks such as running tests, generating a UI, and building core logic using Git worktrees. In the second half, attendees will experiment together by tackling Conway’s Game of Life using parallel agent workflows. Rather than a polished demo, this will be a live coding experiment where participants are encouraged to use their own tools. You will see what works, what breaks, and what it really takes to manage concurrent AI workflows effectively in real world development. NOTE: Ideally bring a laptop with a Copilot/Claude/Cursor/etc account

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Trump, Your Rights, and Resistance,”** an overview of the legal landscape in the District of Columbia just over one year into Donald Trump’s second administration, with Scott Michelman, legal director of the ACLU of D.C. and lecturer on law and Shikes Fellow in Civil Liberties and Civil Rights at Harvard Law School. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-trump-rights-resistance](https://events.ticketleap.com/tickets/profsandpints/dc-trump-rights-resistance) ] Our nation looks a lot different just over a year after President Trump took office in January 2025. What has actually happened—and what does it mean for our rights? Get an informed breakdown on the civil rights and civil liberties issues that have defined the period since Trump's second inauguration with Scott Michelman, a legal scholar who last January gave an excellent talk on the legal guardrails potentially checking Trump’s actions. He’ll discuss what has been happening with immigration policy, criminal justice reform, domestic military deployment, discrimination, and threats to free speech. He’ll identify troubling patterns, explain where advocates have successfully pushed back in the courts, and outline the unresolved concerns ahead. The talk will also explore what individuals can do next, from understanding their rights to participating in elections that will shape the future of this administration and our country.

This month, we'll have a recorded talk, followed by discussion, on API design and single-header libraries. How should we structure and program libraries to impose as few usage constraints as possible? We’ll look at [the STB libraries](https://github.com/nothings/stb) and other examples as case studies. We're still at the West End Library - see the location in the sidebar for details. **Agenda:** \- 2pm \- 3pm: Library discussion \- 3pm \- 4pm: Open\-ended discussions\, presentations\, etc\. \- 4pm \- whenever: We'll go get food nearby\! **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

**[No Surprise, ... YET]** Let's get together and **WORKSHOP** about Job Searching and Career Management. Here are some of the content areas we can cover - expect this to change. * Using AI effectively (search, resume). * Job Search Tooling (i.e. TopResume, Job-Squid). * Resume / LinkedIn Review * Practice Interview * Practice Elevator Pitch ***Bring your laptop and expect to write some (non-AI-generated) code!*** Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
