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 use names of known computers or androids in fiction. My main computer is always Ralf (the computer built by Richie Adler in Whiz Kids), and my main phone is Lal (Data’s daughter). My girlfriend uses other franchises (GLaDOS, Wheatley, Marvin).
