Tonight during dinner I got a call from a coworker. This never happens so I knew it must be an emergency. When I answered I was greeted by a very apologetic, very worried person who had basically pushed a button they shouldn’t have pushed. We’ve all done it, right? Pushed that one button that somehow erases hours (or God forbid, days) of work. Lucky for this person I’ve had enough “oh shit” moments of my own to push me to make copies of code, saving revisions as I go, just for instances like this. Within a few minutes I was able to restore what was lost. Just like that.
