Why was "tantrum" trending last week?
1727, from Japanese samurai "warrior, knight," originally the military retainer of the daimio, variant of saburai, nominal form of sabura(h)u "to be in attendance, to serve."
A hacker who hires out for legal cracking jobs, snooping for factions in corporate political fights, lawyers pursuing privacy-rights and First Amendment cases, and other parties with legitimate reasons to need an electronic locksmith. In 1991, mainstream media reported the existence of a loose-knit culture of samurai that meets electronically on BBS systems, mostly bright teenagers with personal micros; they have modelled themselves explicitly on the historical samurai of Japan and on the "net cowboys" of William Gibson's cyberpunk novels. Those interviewed claim to adhere to a rigid ethic of loyalty to their employers and to disdain the vandalism and theft practiced by criminal crackers as beneath them and contrary to the hacker ethic; some quote Miyamoto Musashi's "Book of Five Rings", a classic of historical samurai doctrine, in support of these principles.
