At my University, they named our Linux systems after birds (Unix are precious metals, Windows are unstable elements, etc). Here are a few, for example:
Host falcon.cs.umanitoba.ca (130.179.28.112) appears to be up.
Host gull.cs.umanitoba.ca (130.179.28.114) appears to be up.
Host hawk.cs.umanitoba.ca (130.179.28.115) appears to be up.
Host loon.cs.umanitoba.ca (130.179.28.116) appears to be up.
Host owl.cs.umanitoba.ca (130.179.28.117) appears to be up.
Host robin.cs.umanitoba.ca (130.179.28.118) appears to be up.
Host sparrow.cs.umanitoba.ca (130.179.28.119) appears to be up.
Host swan.cs.umanitoba.ca (130.179.28.120) appears to be up.
Host cormorant.cs.umanitoba.ca (130.179.28.121) appears to be up.
Host finch.cs.umanitoba.ca (130.179.28.122) appears to be up.
Host killdeer.cs.umanitoba.ca (130.179.28.123) appears to be up.
Host oriole.cs.umanitoba.ca (130.179.28.124) appears to be up.
Today, I noticed something funny -- they named Linux computers after every bird I can imagine, except for one: the Penguin. How silly is that?
