From the Harvard Gazette, Walter Isaacson writes about Bill Gates’ years at Harvard.
It may have been the most momentous purchase of a magazine in the history of the Out of Town News stand in Harvard Square.

Gates began to rock back and forth, as he often did during moments of intensity. When he finished the article, he realized that Allen was right. For the next eight weeks, the two of them embarked on a frenzy of code writing that would change the nature of the computer business.
