Sat, Aug 1, 9:00 AM MDT · Bardo Coffee House, 3333 S Wadsworth Blvd Unit C105, Lakewood, CO 80227 # SOFTWARE FREEDOM FIRST SATURDAY: The Gathering Start the month with your freedom-loving technical friends. Bring a machine. ## Featured Small is Beautiful (SiB) Sessions ### Warner Losh @bsdimp - Where Unix Began — Early Unix in a PDP-11 Simulator Explore where Unix began! Recent discoveries in a storeroom at the University of Utah have given us a glimpse at the earliest version of Unix written in C. Warner Losh will give an abbreviated version of his history-of-Unix talk and put this discovery into context. After a quick demo, he'll show you how to run any of the early editions of Unix we have images for — 4th, 5th, 6th, and 7th editions — in a container running a PDP-11 simulator. You'll see how many familiar concepts were there at the start, discover how they grew, and learn how to run all of these from the convenience of a container. * https://www.tuhs.org/ — The Unix Heritage Society * https://github.com/simh/simh — SIMH PDP-11 simulator * (Warner may share additional links during the session.) ### Will Dickinson @axcien Xonotic — Fast, Free, Fun FPS Xonotic is a fast-paced, free-libre arena shooter born when the Nexuiz community forked the GPL codebase. Will will demo the game live, then throw open the arena: brave, adventurous souls can jump in for a few frags. Pure fun, 100% free software. * https://xonotic.org Maybe install it beforehand if you'll want to play. ### David L. Willson @DLWillson OpenCode — An Agentic CLI Coding Partner You Actually Own OpenCode is libre, modal, and connects to OpenRouter like butter. Willson works in OpenCode with and on his trusty AI assistant "Chip". Let him show you modes, sessions, models, and how to connect to OpenRouter. He'll even give you an API key with a few bucks on it, so you can play with a big, beefy LLM. * https://opencode.ai * https://openrouter.ai **SFS is value for value** * Pay what we ask: https://paypal.me/sfs303/16 * Or, pay what you choose: pwyc@sofree.us
