It took many years of work, by hundreds of programmers, to develop this operating system. Some were paid by the Free Software Foundation and by free software companies; most were volunteers. A few have become famous; most are known mainly within their profession, by other hackers who use or work on their code. All together have helped to liberate the potential of the computer network for all humanity.
