>Hello world!
Among computer scientists, the Bell Labs researchers of the 1960s and ’70s are regarded with a kind of reverence. They are viewed as equal parts Lewis and Clark and Albert Einstein: pathbreaking leaders and intellectual titans. Their legacy is brought home to nearly every student of computing by the phrase “Hello, World.”
The words denote a basic programming exercise devised by Bell Labs technologist Brian Kernighan in 1978. On the theory that we learn best by doing, all novice computer programmers are tasked with writing code that will prompt a computer to display or print “Hello, World.” The phrase is a universal touchstone, the first step in a programmer’s journey.
