React Canvas Thumbnail Generator + Rails Fix for Pinball Ops

In this 404 Tutorial Not Found stream, we’re doing actual dev work — not toy problems, not contrived walkthroughs.

First up, I’ll build a React-based thumbnail generator using the HTML Canvas API. It’ll help me crank out consistent, styled video thumbnails fast, right from the browser.

Then we’ll shift to a real Rails app used by pinball machine operators. Right now, it’s missing a key feature: adding machines to an existing count. We’re fixing that — live.

🛠 What you’ll see:
• React + Canvas to dynamically render thumbnails
• Rails bugfix in a production-facing app
• Real-world decisions, problems, and solutions

Pull up a chair, ask questions, or just watch some practical dev work go down.
