11 months ago I had 12 dead projects and a warehouse job. This week I'm #151 on GitHub's Top Committers in Poland — and just dropped the biggest update of my life.

Monday's post hit 33,000 views, a new personal record (the old one was 28k, three weeks earlier). This series keeps outrunning itself. And today PC Workman v1.7.6 is live: new .exe — download, extract, run, no Python.

Scarred: psutil.sensors_temperatures() returns empty on Windows. That was the proactive monitor's temperature function — the one I built "months ago." It was reading None every single check, doing nothing, for months. Found it this week and switched to LibreHardwareMonitor. The scariest bugs don't crash your app — they pass every test because they never ran in the first place.

Ten weeks. Never missed a post. Monday plan. Wednesday code. Friday truth.
