So I've got a friend learning Java, using Eclipse.
I walk in one day and see him restarting his computer. I make nothing of it. Few minutes later, he's restarting again.
I jokingly say "Windows update?"
He responds with the straightest face ever: "No, compiling code."

Apparently he thought you needed to restart the computer before compiling.
Not sure if I should be mortified or laughing my ass off.
