My first VPS was for a Minecraft server so I named it cobblestone. I've kept using Minecraft related names for all my machines since then, and I try to pick ones that are at least vaguely related to the function or appearance of the machine. For example my cluster has brute for the master and piglin01-piglin04 for the workers, but those are the only ones I've numbered.

The exception is my two Klipper RPi's, one is octopi since that's what it originally ran, and the other is named after the model of the printer. For some reason I never named my printers.

I probably wouldn't use a naming scheme like this for production servers though - I'd either go with functional hostnames or something like the periodic table which you can pick from arbitrarily. My home servers and clients aren't cattle though, so I like having a little personality to the names there.

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.

Workstations machines get first name type names that are inspired by the brand of the machine. This asus is named adam.

I always name my PCs with characters from the book I'm currently reading. Here are a few: Teatime, Cthulhu, Dirk, Horus, Binky, Pteppic

I also use mythological names. Specially god names and mainly egyptian gods:

Anubis is my main one, 24/7 server. Ra is the one i use to experiment with and Zeus is my vps with vpn

For some very specialized cases that i used in the past for my Raspberry pi 4, i used Odin (i installed Huggin there), Tenjin (no reason at all, i just like it) and Khonshu

I use famous programmers. First Linux server was Torvalds, first mac was Woz, currently in service I have Kernighan (one of the inventors of C), KJohnson (Katherine Johnson was a programmer for NASA) and Shamir (The S in RSA).

Travolta, Stallone, Dr.Jacoby, BlackMamba

Neptun for the Hardware running Proxmox

Docker-Server-1 and so on for the VMs

Swedish city names, but only the ones with pure english characters to avoid hassel 😅

Kiruna

Halmstad

Lund

Etc...

Delta, Epsilon, Beta, rpi01, rpi02...

tools for my docker host with most services running on it truenas for my truenas host p01-p03 for my VPSs gpu-linux for my AI art and LLM machine

desktops and laptops are all misc strings that windows or Linux comes up with at install time

My current server is proxmox2, guess why. It runs servers HassOS, OMV and so on.... My desktop is called desktop and my laptop is called with its brand. 🤷

Everything has some sort of top:

Slacktop, craptop, proxtop, oldtop, wifetop, and batocera (because I keep forgetting to ssh in and change it).
