Linux

Linux /lee’nuhks/ or /li’nuks/, *not* /li:’nuhks/ /n./ The free Unix workalike created by Linus Torvalds and friends starting about 1990 (the pronunciation /lee’nuhks/ is preferred because the name `Linus’ has an /ee/ sound in Swedish). This may be the most remarkable hacker project in history — an entire clone of Unix for 386, 486 Pentium, Alpha, and Sparc machines, distributed for free with sources over the net. The secret of Linux’s success seems to be that Linus worked much harder early on to keep the development process open and recruit other hackers, creating a snowball effect.

“Linux is a free Unix-type operating system originally created by Linus Torvalds with the assistance of developers around the world. Linux is an independent POSIX implementation and includes true multitasking, virtual memory, shared libraries, demand loading, proper memory management, TCP/IP networking, and other features consistent with Unix-type systems. Developed under the GNU General Public License, the source code for Linux is freely available to everyone.”
