You think you're peacefully sleeping, but underneath your mattress there's a literal demon running Docker containers, syncing cloud backups, indexing your entire codebase, downloading OS updates, and probably mining crypto for all you know. That laptop fan spinning at 3 AM? Yeah, that's not a bug—that's your computer living its best life while you're unconscious. Background processes don't sleep just because you do. They're like that one coworker who sends Slack messages at 2 AM. The real kicker is when you wake up to a dead battery and wonder what your machine was doing all night. Spoiler: everything except what you actually needed it to do.
