I'm working on resolving defects for the current project I'm on. One of the defects is that, intermittently after a reboot, a particular machine configuration can display something a little odd under certain circumstances.
Gotta reproduce, so that means reboot, reboot, reboot...
I got a puzzle called "Masterball" from my aunt like a month ago. (This will all tie in, just wait.) It's sort of like Rubik's Cube, but a sphere instead of a cube. I mixed it up and have been messing with it on and off ever since.
The defect resolution:
Both rebooted and logged in/out several times in succession. Solved "Masterball," a puzzle similar to Rubik's Cube, while doing that many reboots, but was unable to reproduce the noted defect.
Very, very stimulating stuff.
