A former Series B engineer who developed Repetitive Strain Injury built a desktop widget to quantify the hidden physical labor of programming. Using Rust and Tauri v2, he calculated that his daily typing amounts to lifting 500kg, a staggering figure based on standard keyboard switch actuation force. This personal project transforms an invisible strain into concrete data.

The developer chose a low-level polling strategy over traditional OS hooks, checking key states every 50ms. This decision prioritized stability and privacy, avoiding the permission hurdles common on macOS. The result is a 'Health Bar' system that drains as you type, visualizing coding energy like a video game's HP. It's a clever, non-invasive approach to a complex problem.

His free tool, The Burnout Meter, runs locally without sending data to the cloud. For developers battling RSI, this offers a tangible metric for a persistent issue. It reframes typing not as a light keystroke, but as a daily workout, prompting a crucial conversation about the physical realities of our profession.
