I have NekkoDesktop, NekkoLaptop, NekkoLaptopJr (new laptop) and NekkoServer :) (Phones are just Nekko with release being S9 and S21 for Samsung or G6 for LG)

I use names from FFXIV.

For my work-related VMs, raid bosses. It makes it easy to spot my VMs because nobody sane would name them stuff like Erichthonios or Hippokampos. Unfortunately I had to draw the line at 724P-Operated Superior Flight Unit A-lpha.

For my home server VMs/CTs, I use the names of the gods - Byregot, Rhalgr, Azeyma, etc. and Eulogia for Proxmox itself.

desktop, laptop, server. Lame but always clear.

I name them after fictional robots/AI

PC is Deep Thought, laptop is Wheatley, phone K9 in etc

Culture ship names. https://theculture.fandom.com/wiki/List_of_spacecraft

I go with a UUID so I never duplicate. 🤪

my old desktop was named George, inspired by the word “GeForce” on the gpu. my new one is Leo, mostly because I just like that name, but also because it’s my first desktop built for linux. My first server was Bertha bc its physical size was a lot bigger than I expected and I had to find a new place to store it, and my newest server is even bigger so I named it Marge. My clunky old 16" laptop from 2010 is named Mondo.

Moons of Jupiter.

I use work for work machine, and home for home

My PC is just arch Linux and my laptop is computer

PC. Privacy reasons

I use LoL champs, there’s at least one for every letter of the alphabet

Similar to other people:
laptop-56
phone-56
server-56 (or the actual domain name…)
…palmtop-56 (I’m not sure if that’s actually possible)

I like the look of all-lowercase hyphenated words. And “56” is a conveniently short identifier I use for myself.

charlemagne for my desktop, and invictus for my laptop - no particular theme, just liked the names lol

My servers however previously used gods from Greek mythology though, as controversial as that apparently was (?)…

(To be fair, I think the controversy was regarding doing that in a professional / enterprise environment of which I am definitely not in)
