The Philosophy of Open Source
Ben MillerDirectorSauk City Library
Free or Open Source?
The term open source software is used by some people to mean
more or less the same category as free software. It is not exactly
the same class of software: they accept some licenses that we
consider too restrictive, and there are free software licenses they
have not accepted. However, the differences in extension of the
category are small: nearly all free software is open source, and
nearly all open source software is free.

Good programmers know what to write. Great programmers know what
to re-write (and re-use).
