Mimicing a thread I saw elsewhere.
I generally use this list to name my machines: https://en.wikipedia.org/wiki/List_of_mythological_objects
For my main server I use loeding: a modified version of Lædingr, a chain forged by Thor to bind and were broken by Fenrir. (Norse Mythology)
I don’t really name my servers anything special (just hperrin-server, smtp1, smtp2, etc), but I like to name my projects after figures in Greek mythology.
