On my labs cluster they are named after famous physicists

At my first job/internship it was fish names (they were dev/qa servers so wiped almost daily): Crappie, Bluegill, Walleye, Marlin, etc.

Current job is medical so it's all professional (i.e gr01sec02, gr02sccm01)

At home I've got a couple of naming schemes for different device types.:

Phones: i-telleuwat(last 4 of the number)
PCs and Media centers: playon(last octet of the IP)
Servers:gimme(service thats hosted)

I recently switched to using the periodic table. I made myself a nice little spreadsheet to keep track of it all. I used to name hosts after random stuff like cereal, snacks, or just plain old [my first name]-desktop.

cakes then a different type of cake. ie cakesFlan

I have a weird one: years ago I called one machine "nudl" (like using one's noodle but with a weird spelling). Now I've got a few different nudls, a strudl, a dudl, and I think there's a pudl in the closet somewhere.

Bird species, most of the time. I look for a bird that seems to have some connection with the intended purpose of the box, then use that. e.g. my work computer's hostname is cormorant.

US states. If I have more than 50 different host names to manage, I should re-evaluate my hobbies. And then lazily move on to US state capitals.

I use harry potter characters

My Raspberry Pi's are named after planets and large bodies on the Solar system.

My servers are named after The Expanse characters and ships.

VM's and CT's after their usage with a tag in Proxmox for the OS used.

Not just for devices but also my hard drives, I use the names of stars. For example Rigel or Betelgeuse

In college, they were all the secret identity for versions of the Flash. Since then, I've expanded to other comic book super heroes.

i use all the naming schemes. douglas adams, astronomy, greek letters, star trek ...

have to come up with a new concept every other machine.

All of my personal machines are Autobots.

At work we use space probes (Voyager, Pioneer, New Horizons, etc). We're a small satellite communications company.

My server is named Yggdrasil and my devices are named after the 9 realms.

I name mine after fictional planets.

We did reindeer; Dasher, Dancer, Vixen, etc.

I used names of fictional robots, androids and self-aware computers (though I avoided HAL for obvious reasons) for a long time. These days my wife and I usually go with an indirect reference to the function or hardware - Ex. a device named Anathema, or a Raspberry Pi server named Marie (as in Marie Callendar, a former local pie/restaurant chain). I had an expendable frankenputer for tinkering that I called RedShirt.

Currently trying to come up with a name other than Chris for the PineTab 2.

Edit to add: Places I've worked have used Roman emperors, drink brands, Simpsons characters, and of course basics like "IIS1" "MAIL4" "QA-3" and so on. Some would add numbers to the names sequentially, others would use the last octet of the IP address.

I name my machines after my cats.

Sounds like you could start using the names of moons. But a pantheon does sound like a good system too, should also include the titans.

For work - No need to divulge. It's work/corporate standards likely similar to some folks that have listed here give or take some characters.

For home, Venture Brothers characters.

Used to use characters from Madagascar, swapping over to dankpods references. Dingus, Frank, Sexy Speaker, Old Mate Senny.

2nd ww navy vessels (inspired by kancolle)

personal machines - destroyers
servers - battleships

I do models for laptops and case names for my built desktop. So Dell-3590 or my desktop is NR400.

I know who has what so its easy to manage if i want to cut off network access or transfer files.

pi

pi3

pi3v2

space

fusion

magnet

qdivision

Meta machines on my system offer data. Infra machines on my system run the network (infrastructure). But my favourite is naming all my HDD’s platters; Media Platters, Service Platters, etc.

I do robots from video games, movies, TV shows, etc.

Royal-Cat-(Computer type)

for example, Royal-Cat-PC or Royal-Cat-iPhone

I've not played for years but I still have a YuGiOh cards naming scheme.

Usually just names/lyrics of my favorite songs
iPhone: ByeByeBaby
AirPods: You're on your own, kid
Laptop: InnerMonologue
Except just for fun, I named my HomePod Cortana

looks like I'm one of the many that use Star Trek ships for my naming scheme:

Enterprise - My gaming PC
Kumari (Gen. Shran's ship) - my debian laptop
Defiant - another debian laptop (a two-in-one ultraportable)

I use the names of females that have (had) significance in my life.

Mine are named after mythical Asian creatures.

Phoenix, Kirin, Yuki-onna, Dragon, Kodama, etc etc

Mine machines are all named after Final Fantasy Summons/Espers/Eidolons/Aeons/Primals.

My main proxmox node is Bahamut. I try to pick a suitable summon that matches the host but that doesn't always work.

Futurama characters: Farnsworth, Calculon, Nibbler, Wernstrom, Clamps

My devices are all named after things from the Star Wars universe, in particular:

• Stationary computers are named after planets (my "main" PC is Coruscant, the old "main" that was Coruscant before is now Corellia, etc.)
• Laptops are named after mega-stations (DeathStarI, DeathStarII, Starkiller, etc.)
• Tablets and comparable sized devices are named after giant starships like the Super Star Destroyers (Executor, Lusankya, KnightHammer, etc.)
• Mobile phones are named after regular sized starships (like Tydirium, TantiveIV, SlaveI, EbonHawk, etc.)

urmom = main pc

fbi = rpi 4 with docker + pihole + 2x unbound

*bble. Rabble Ribble Pebble Pibble Tribble Rebble Jibble Jabble Etc...
