ArsDigita
A web development company which started in Boston, MA in the mid-1990s and flourished at the peak of the Internet bubble, later falling on hard times before eventually being acquired by Red Hat in 2002.
Its founders set up a nonprofit organization, the ArsDigita Foundation, which sponsored a yearly programming contest for high school students and, in 2000, a free physical school teaching an intensive one-year course in undergraduate computer science.
