Is the Web your canvas?
Are JS, CSS and HTML your brush,
Node.js, VSCode and DevTools your easel,
or React, D3 and Three.js your siege engines?
Or would you just like them to be?
Whether you're working on a web site, web app or web startup,
if you care about logic, data structures and natural intelligence™
beyond their framework abstractions and artificial boilerplates,
let's get together to discuss routing, hydration, effects, design, standards, verification, optimization and more.
Drop by for a casual exchange of knowledge, feedback and curiosity while we work or chillax with a coffee.

A Rabid Dane
Enjoys the Pain!
Rabid Danes Hash House Harriers is a non-competitive running social club with a focus on running/jogging/hiking in nature. Trails cover a distance of apx. 15 km. Hash traditions apply: we do not know in advance where the trail will lead us, but we will figure it out together.
Walkers and joggers start at 10:00.
Runners start at 11:00.
Unlike our weekly runs, everyone follows the same trail, there are no shortcuts.
The lunch is usually served from 13
The run fee of 75 DKK covers all the food and drinks after the run (picnic style), including beer/water and hot cocoa.
Remember to bring a bag with spare clothes for after the run. You don't have to carry the bag during the run, as there will often be a bag car.
We look forward to seeing you!

Omnipresent Atheists Weekly Meetup (3rd Tues)
Jimmy V's Grill & Pub in Grandview Heights. We meet in the bar in the room on the right (the cigar shop). You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room.
This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us.
COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant.

Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!
Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life.
Mission: grow, support, and provide community for atheists in Central Ohio.
Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision.

What If Your AI Could Be a Team? - Chad Green
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise.
We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration.
Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team.

Prompt vs. Paintbrush
AI is changing how art is made. But when does it stop being your work and start being the machine’s?
This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation?
We encourage audience participation during this event that will be moderated by Chris Slee.
Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
