Decentralized Systems & Applications

A weekend about real communication. We will sit in a circle and explore what happens when people slowly stop performing and start listening more honestly. It is a three-day Community Building workshop in the tradition of M. Scott Peck — for people who want to understand themselves better in contact with others. How do I speak when I am afraid? How do I listen when someone is different from me? What do I hide? What makes real closeness difficult? The weekend will be held in Czech with English translation. Facilitated by Hana Perglerová and Karol Herian from Community Building CZ. VENUE ATMA Community Space Vítkova 10, Prague 8 PRICE From 11 May: 5100 czk. Accommodation and meals are not included. Each participant arranges their own accommodation and meals. If the price is a barrier, please contact the organisers — individual arrangements may be possible.

Over a billion documents processed. Millions of Veterans impacted. Hundreds of thousands of employee hours saved. Faster decisions. Greater accuracy. More benefits in the hands of our disabled Veterans. We created Smart Search, the world’s largest consumer of Amazon Textract, right when GenAI began reshaping what’s possible. Since then, we’ve built a suite of AI‑driven solutions that transform this data into real, measurable outcomes—accelerating benefits decisions for our Nation’s Veterans. Join us for a focused conversation on how an outcome‑driven approach to AI is helping us boost accuracy, streamline workflows, and deliver faster results for those who have served. This is a follow up to the AWS re:Invent 2023 "Intelligent Document Processing with Gen AI for Public Sector" presentation.

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
