"a Gypsy; the Gypsy language," 1812, romani, fem. of romano (adj.) "Gypsy," from rom, the Romany word for "man, husband, male, Gypsy" (plural roma), from Sanskrit domba-s ("with initial cerebral d, which confuses with r" [Klein]) "male member of a low caste of musicians."
1975, transitive, "start up (a computer) by causing an operating system to load in the memory," from bootstrap (v.), a 1958 derived verb from bootstrap (n.) in the sense of "fixed sequence of instructions to load the operating system of a computer" (1953).
This is from the notion of the first-loaded program pulling itself (and the rest) up by the bootstrap. The intransitive use, of a computer operating system, is from 1983. Related: Booted; booting.
former transliteration of the name of the Chinese capital city, now (in the pinyin system) called Beijing. In the Wade-Giles system it was Peiping; the form Peking pre-dates Wade-Giles and was formed by the old British-run, Hong Kong-based Chinese postal system. Peking duck, "large domestic duck of white plumage and orange beak and legs," is attested from 1880.
