- 3. What are Linux and Open Source? What is Linux? UNIX-like operating system Developed by open source "community" Packaged and shipped by distributors such as Red Hat, SuSE, Turbolinux, ... UnitedLinux = open industry consortium providing a binary-compatible Linux distribution What is Open Source? Community develops, debugs, maintains Generally high quality, high performance software "Hello everybody... I'm doing a (free) operating system (just a hobby, won't be big and professional...)." Linus Torvalds, creator of Linux, from the first Internet announcement on August 25, 1991. Even he initially underestimated its potential.
