Simulating The Unix at With Emacs (opens in new tab)

Charles Choi has a nice post on simulating the Unix at command with Emacs. Back in the old days, Choi used to use the Unix at command to notify himself of various events. In macOS, the at command is disabled by default because its use can deplete the battery. Old habits die hard though, and Choi wanted a way to get the same behavior.
