We’re getting closer to winter. I’ve got most of those preparations done. “Just” have to finish building the heater for my shop. My programming based project list is coming together: learn me some Rust, contribute some documentation to a project I’m following, look deeper into the potential of the Accessibility tree. That should keep me busy for a while!
