A kernel (NOT an operating system in and of itself) used to power the GNU operating system components. This makes up a relatively stable, free operating system known as GNU-Linux.
Linux, free as in speech (and hopefully beer!)

NOT AN OPERATING SYSTEM!!!!!!!!

Linux is a KERNEL, NOT AN OPERATING SYSTEM started by Linus Torvalds in 1991 at University of Helsinki in Finland. Linux was at first just a hobby for Linus. Linux is free software.

It just so happened that just when Linux was getting usable, GNU had everything it needed except a kernel. Thus, people started using Linux with GNU to make a completely free UNIX-like operating system called GNU/Linux.

Today Linux and GNU/Linux have come a long way from the early 1990's, although they're still mostly used by geeks.
Linux is at version 2.6.xx as of mid 2005.

GNU/Linux is about empowering users to a choice. Linux is a kernel (guts of an OS). GNU/Linux is the kernel with GNU tools to form a complete OS.

GNU is a software revolution that is open and free in every since of the word. The code (software) is open to anybody to download and/or modify as long as you share the modifications with others. This is an open concept like university research. Everybody benifeits from the colaboration of others. In a closed enviornment inovation and quality are stifiled.
heep://www.urbandictionary.com uses Linux and very glad to see they know what they are doing by using php.

Live free or die!

An excellent operating system that is more stable than Microsoft's Windows. Good for server use, but not practical for the average (aka home or gamer) user since it isn't compatible with most programs.

Notably used by either people who do know what they're doing, or immature idiots who think they're "l337" because they spited "M$" out of money (and seemingly wrote 90% of the definitions on this word as well).
Linux is a good OS, but it's most vocal users are hypociritcal idiots.

Linux is simply a word used to get OS Fanboys to spark a religious war.
Linux Fanboy: Linux, enough said
Windows Fanboy: MS rules and Linux sucks because no one uses it
Macintosh Fanboy: I'm cooler than the both of you because my OS is shiny

The Operating System that POWERS urbandictionary you assholes.

Go on to www.netcraft.com
Then look up "www.urbandictionary.com" on the web server search. I see SEVEN linux servers, and 2 netbsd/openbsd servers.

I was able to install Mandrake Linux on my computer without any help, BECAUSE I RTFM! Like when I first installed WINDOWS!!

All the people who said shit about linux either:
1) Heard about it from Microsoft
2) Heard about it from SCO
3) Heard about it from some anti-linux group.
4) Saw a friend use Slackware
5) Saw a friend use the terminal.
6) Tried using Slackware as their first distro.

Linux is a great computer for all uses except crashing on you.

Ubuntu, Suse, Mandrake, and MEPIS are great linux distros that offer excellent user friendliness WITH GRAPHICAL TOOLS. So you don't even HAVE TO USE THE FUCKING TERMINAL!!

Only thing you can't do is run Windows stuff, like WINDOWS AIM, and WINDOWS EXPLORER, so don't even try doing stupid ass stuff.
Dumbass:: Linux sucks because there's no aim client.
Me:: Dumbass, AIM FOR LINUX, GAIM, KOPETE, LICQ, and NAIM!

An open source operating system that tends to get more secure and desktop ready everyday!!
To break a Linux box, you will have to work at it..
To break a Windows box, you just have to work on it..
