Initially, my machines were named after classical philosophers and mathematicians (starting with Euclid, after the computer in Pi, but then proceeding to Plato, Aristotle, and Archimedes). However, Plato & Aristotle died almost simultaneously, and I switched to a non-classical schema focusing on mathematicians with Descartes, Liebniz, and Hume. Currently, my network consists of: Vonneumann (the server), Erdos (my work machine), Hilbert (my smartphone — because Hilbert is associated with both infinite hotels and space-filling curves), and Agrippa (the chromecast). Retired names include Godel (the PDA), Cantor (a now-dead server), and Conway (a laptop, named after John Conway of Game of Life fame).
My girlfriend used to name her machines after historical figures she was indirectly related to (Isaac for Isaac Newton, Tesla for Nikola Tesla — both of whom died virgins but who are great^n uncles). She now names devices in her network after characters from Ghost in the Shell (Motoko, Bateau…)
