🚀 What are UUIDs and why might I need them? – The Eclectic Light Company
It’s easy to generate a UUID in Terminal: simply type
uuidgen
and that command tool will return a fresh UUID as its response, neatly formatted using the standard layout. There are also equivalent calls available to software through the UUID structure in the macOS Foundation API. You can use those to verify that UUIDs generated close together in time are actually very different indeed.
I don’t know what I need this for, nor whether I will ever remember I bookmarked it, but it looks cool and I have the feeling some day it might pay off to keep it. #geekery
