Goose barnacle migrate, it was thought that barnacle geese, "Branta leucopsis", developed from this crustacean, since they were never seen to nest in temperate Europe, hence the English names "goose barnacle", "barnacle goose" and the scientific name "Lepas anserifera" (, "goose"). The confusion was prompted by the similarities in colour and shape. Because they were often found on driftwood, it was assumed that the barnacles were attached to branches before they fell in the water. The archdeacon of Brecon, Gerald of Wales, made this claim in his "Topographia Hiberniae". Since barnacle geese were thought to be "neither flesh, nor born of flesh",
Barnacle (slang) to repair design errors, experiment with design changes or enhancements, or otherwise alter circuit behaviour. Although usually a barnacle-implemented change is incorporated into a new fabrication cycle circuit before production, occasionally there are final-assembly barnacles. In such cases it is determined to be less expensive to add a barnacle to a final, shipping product rather than re-spin the circuit to ship without these interventions left in place. The normal development cycle for electronic hardware contains two main phases. The first phase is the development and prototype phase in which the hardware is first designed (and often simulated using a computer
