In 1957, John Van Gardner developed a system to compare the check sums of loaded sections of Fortran programs to debug compilation problems on the IBM 704.

Famous quotes containing the word historical:
“It is hard to believe that England is so near as from your letters it appears; and that this identical piece of paper has lately come all the way from there hither, begrimed with the English dust which made you hesitate to use it; from England, which is only historical fairyland to me, to America, which I have put my spade into, and about which there is no doubt.”
—Henry David Thoreau (1817–1862)
“We need a type of theatre which not only releases the feelings, insights and impulses possible within the particular historical field of human relations in which the action takes place, but employs and encourages those thoughts and feelings which help transform the field itself.”
—Bertolt Brecht (1898–1956)
