I'm a prospector by hobby, I tend to name everything as minerals. I also use Greek mythological names, plant and insect types, as purpose specific tags. Mobile machines are named as lightweight and usually non-sessile entities, such as 'FireFly' (a 'Droid) and 'DragonFly' (a laptop) .. Machines in my recording studio are named for the 9 Muse, like Euterpe and Polyhymnia. My Router's name is 'Calcite' and my local SSID is "Merlins Crystal Cave" ...

There is one exception: a series of machines dedicated to the design and implementation of some IP I'm commercializing: These have been named by the acronym for the corporation which is funding that project suffixed with the German syllable for 'Make': LECmachen. These have become a series; LECmachen1, LECmachen2 and so on.

Characters from whatever book I'm reading or have recently read. Co-workers were OK with saphira but seemed to have issues with glaedr; probably should have gone with thorn instead.

At work, a suggestibe nickname of field group activity (people working together) supplemented by a running index.
At home/travel, brand plus model.

Mythical places, like Narnia, Xanadu or TheUpSideDown.

In my engineering office, I use the international names for physical units that actually are named after people, Volta, Ampere, Henry, etc.
At my Broadcast Radio station they are the names of the original WABC, musicradio77 djs. Ingram, Lundy, Morrow, Daniels, Anderson, etc. the server is named after the Program Director Sklar.
For a while Rutgers University named its servers after fish. Flounder, Bass, etc.

I concatenate the name of a person with a place.

Boringly, the boxes on this family LAN are named after the Christian name of the user, except of course for the IPCop firewall box, which has imaginatively been called "wall".

As a nerd often have: h@ck or gnu@Linux &c...

Not for host names. @ and & are invalid characters. If you send mail, you cannot send it to a user with a hostname of h@ck... the address would be user@h@ck... Which is invalid.

My friend in Boston uses tree types, I myself prefer to use names of beers.

I mean in a terminal that is how it shows up with h and ck or gnu and Linux &c=etc... next time I should try for v@gue

Greek and Roman mythology for me. Polyphemus, Prometheus, &c. Used Hermes for the Acer that was the fastest computer I had had until that stage. Some years just abbreviate the computer brand, eg "toshi" for the Toshiba Satellite.

At home I use animal names. (bear, monkey, lion, etc..)

But at work I use descriptive names that show both the machine type, department and designation. (admpc5, engnb1, DC4, prnsvr12, ESX1, etc...)

Not very creative I know. But easy to remember, document and scale up.

I'm afraid I am not as creative. I use descriptive names, desk for desktop, plus the room it usually is in.
