"Always code as if the guy^Wold lady who ends up maintaining^Wrunning your code will be a violent psychopath who knows where you live^Wwork."
Not long after, at an engineering holiday dinner, an exec was asking everyone about their hobbies. That same engineer proudly shows a photo on their phone, of themself posing with a huge black tacticool sniper rifle.
I might've looked taken aback, because the exec then asked if I shot guns. Nope.
Refer back to the old saying, in the training.
The engineer did good work, and seemed to be a decent person, but it's still a little funny that they turned out to be immune to the layoffs (by that same exec) that eventually got me and almost everyone else.
