Note that most of the sites in the com and edu domains are in the U.S. or Canada.
us
sites in the U.S. outside the functional domains
su
sites in the ex-Soviet Union (see kremvax).
uk
sites in the United Kingdom

Within the us domain, there are subdomains for the fifty states, each generally with a name identical to the state's postal abbreviation. Within the uk domain, there is an ac subdomain for academic sites and a co domain for commercial ones. Other top-level domains may be divided up in similar ways.
interrupt 1. [techspeak] n. On a computer, an event that interrupts normal processing and temporarily diverts flow-of-control through an "interrupt handler" routine. See also trap. 2. interj. A request for attention from a hacker. Often explicitly spoken. "Interrupthave you seen Joe recently?" See priority interrupt. 3.

In a restaurant, after several fruitless attempts to get the waitress's attention, a hacker might well observe "She must have interrupts locked out". The synonym interrupts disabled is also common.

Some Usenet jargon has been adopted on IRC, as have some conventions
