I’ve always thought “imaginary” vs “real” was an unfortunate naming convention.

I don’t know about other fields, but electrical engineering uses imaginary numbers with AC circuits and changing electrical fields. Since electricity moves as waves, imaginary numbers let you represent what’s coming 90 degrees later in a compact way.

I’m not sure how Ansible made it on your list. Ansible lets you apply configuration and ensure applications are installed on groups of machines. It works across a variety of Linux distros.
