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 tend to use objects in space. My media server is called phobos, and my AzuraCast server is called dorado.
They’re a bit meaningless, though, so when I do my planned server upgrade this year I’m going to go with something different. My pfSense server was called sibyl, so perhaps something along those lines.
