The AWS Sustainability Hackathon is a 2-hour micro hackathon where students will vibe code and build an app focused on sustainability using AWS in some capacity. Bring 2-3 friends for a fun, creative, and collaborative way to meet like-minded people, explore cloud tools, and turn ideas into something meaningful. Winners will receive merch and a $50 Amazon gift card each, and free food will be provided.

​This meetup is for anyone building with OpenClaw (& Claude Code) or experimenting with other AI tools to create agents that can act and make decisions on their own. If you haven’t tried these yet, come hang out, ask questions, and see what others are building. We’ll trade notes, troubleshoot setups, and explore what it takes to run these systems openly on the web instead of inside closed platforms. Bring your laptop, grab some power, and jump into a night that feels part LAN party, part live build session, where people test ideas and show what their agents can actually do. 👉 [RSVP on LUMA](https://luma.com/53dx7no1) We’ll also have some fun by running a live test to see if a few of our agents can send Bitcoin back and forth and talk about why that’s a meaningful step for autonomous AI. It’s a chance to connect the dots between open AI tools, Bitcoin, and the wider goal of creating technology that no one can turn off. 👉 [RSVP on LUMA](https://luma.com/53dx7no1)

Title: Potential Applications of Negative Radiation Pressure in Astronomy, Medicine and 2WQC Date: April 19 2026 10:00 am - Noon EDT (16:00 - 18:00 CET) Abstract: While we are used to heating and pushing with light, there is also optical cooling and pulling. I will talk about negative radiation pressure, potential ways to generate it, and its novel applications, like non-ionizing medical scanners, 2WQC (two-way quantum computers) in theory solving NP problems, also potential astronomical sources and their observation. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems.

Title: Foundations of Localized Symmetry Mathematics Date: April 18 2026 Noon - 14:00 EST Summary: The moment you use Euclid’s definitions of points and distances in any of your mathematical axioms, all that follows is assured to produce some level of nonsensical results when applied to the foundations of physics. The reason is not complicated: Euclid’s definitions are deeply mired in accepting as a “given” the very concepts that emerge only in well-defined inertial frames, which in turn are local instances of symmetries that are always finite and context dependent. In this talk, Terry will discuss how reframing mathematics in terms of symmetries that, as in the real world, are finite, composite, and dependent on self-observation (acceleration), results in a richer and far stranger set of mathematics in absolute conservation of quantum numbers generate local and global symmetries — the opposite of Noether’s theorem — that in turn create the emergent classical phenomenal such a particles, fields, space, and time. Speaker: Terry Bollinger is a computer scientist with BS, MS, and professional degrees from the Missouri University of Science and Technology.

We'll come together to talk about writing custom apps. Macoy Madson will show how he applied Handmade principles to creating a custom CAD application for a manufacturing company. He will go over the various features and his criteria for what he picked to build vs buy, as well as lessons learned from the shortcomings of his choices. If we have time, we'll also look at compiling native code to WebAssembly. **Agenda:** \- 2pm \- 3pm: Custom app presentation and WebAssembly \- 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.

Curious about “vibe coding” but not sure what it actually means? This beginner-friendly talk is about how people are using AI to build websites, apps, automations, and small software projects by describing what they want in plain English. We’ll cover what vibe coding is, what AI is good at, where it falls short, and how to actually use it without getting lost. The goal is not to hype AI as magic — it’s to show how to use it as a practical tool. This session is designed for beginners, curious builders, non-programmers, and developers who want a clearer picture of how to build with AI today. Topics include: * What “vibe coding” means * What AI can help you build * Where AI is useful and where it is unreliable * A simple workflow for building with AI * Prompting tips for better results * Common beginner mistakes to avoid If you’ve ever thought, “I have an idea, but I don’t know how to build it,” this talk is for you. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

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.

**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. **YouTube Link** TBD
