Computers, unix

ComputerWorld reports that Unix turns 40.  Why would anyone but the geeks care about this birthday? Because just about everything that works well on your personal computer has Unix roots – except for the graphical interface which came from Xerox PARC.

  • The hierarchical file system in which a directory contains files and other directories which in turn contain files and directories, etc, etc.
  • Linux, an open source Unix, runs most of the web servers of the world.
  • Sockets, a programming layer on top of  the TCP communications protocol, first appeared on BSD Unix. All of the web and email services we rely on is built with sockets.
  • Open source started at UC Berkley with BSD.
  • Tim Berners Lee invented the world wide web on a Unix based NeXT system using BSD Unix and  sockets.

Happy 40th Unix!
