Partnership in a law firm has introduced me to some new categories of vocabulary. I am still learning words in rafts and batches these days, but now I am paid to be a professional student.
A few years ago I was learning commercial leasing jargon because my joining the partnership was coincident with our negotiating a new ten-year lease.
This year is the Year of the Server. One day, I'm minding my own business, puttering along peer-to-peer with my faithful paralegal. We upgrade to a file server which turns out to have not quite enough juice and wham! I'm up to my ears in VUP CALs and residential gateways.
At least now I know what a "decently-spec'd file server" is now. Even if I don't have one yet.
