Nothing like that moment of pure terror when you realize you've created a literal tilde directory (~) in your project instead of referencing the home directory... and then proceed to run rm -rf ~/
to "fix" it.
For the uninitiated: In Unix/Linux, the tilde (~) is shorthand for your home directory where all your personal files live. Running that delete command would nuke your entire home directory—years of work, configs, and those vacation photos you never backed up.
Seven years of terminal experience and we're still one distracted moment away from digital armageddon. Just another Tuesday.
