vi: the visual editor

In 1976, a University of California Berkeley student by the name of Bill Joy got sick of his text editor, ex. So he hacked it such that he could read his document as he wrote it. The result was "vi", which stands for VIsual editor. Today, it is shipped with every modern Unix system, due to its global influence.
