Pronunciation: LIH-nucks or LIE-nucks

1. A reimplementation of the UNIX operating system kernel, written by Linus Torvalds, and distributed for free on the Internet. Linux has acheived remarkable compatibility with UNIX, from the point of view of a programmer compiling his software from the source code. Software originally written for UNIX can usually be compiled to run on Linux with no modifications. Linux binaries cannot run on UNIX systems that don't have Linux compatibility on purpose. Linux can be made to run binaries from SCO OpenServer via the Intel Binary Compatibility Standard (IBCS).

Linux is more compatible with UNIX systems that descend from UNIX System V than it is with BSD systems such as FreeBSD.

2. The Linux kernel, bundled with application programs like those that come with UNIX. When these applications are products of the Free Software Foundation, the combination is called GNU/Linux (the G in GNU is pronounced).

When the kernel is combined with applications, the result is called a Linux "distribution." Some distributions are commercially sold and have their own brand names.

3. A registered trademark of Linus Torvalds.

4. A religion practiced largely on the USENET newsgroup comp.os.linux.advocacy. The primary ritual of Linux is arguing endlessly with one of two denominations of Linux practitioners: Linux advocates, and Windows advocates, over whether or not Linux is better than Microsoft Windows. The arguments that make up the ritual can be divided into five categories: Linux sucks, Linux rules, Windows sucks, Microsoft sucks and personal insults.

Linux practitioners are even more fervent than computer users who engage in other so-called "religious wars" such as the classic EMACS vs. Vi.

3. A registered trademark of Linus Torvalds.

Linux (the operating system) looks and feels very much like Sun Solaris, despite the fact that it is not based on the original UNIX kernel, and even its shell commands are complete rewrites of the originals.

GNOME, the graphical interface of Solaris, was written for Linux first.

Since its inception in 1991, Linux has become the most popular UNIX-like operating system, beating Solaris, and even UNIX-based Mac OS X.
1. ~ 2.6 does better under heavy load than ~ 2.4 did.

2. We have a web server running Red Hat ~.

What I use for development of HTML, JAVA, PERL, C, C++. Very stable, but does not have much software that can run on it, because of lack of knowledge about it on the part of the general public. Great for webservers, but until people decide to create software for this system, buggy, backdoored systems like windows will have to do. Linux is often used by professional developers, webmasters, advanced computer users, and people who are able to get off their arse and install it for the sake of their privacy. Some versions (i.e. Red Hat) are relatively easy to install, and can be found free in libraries. Other 'distros' can be found on the internet, but may be harder/easier to install. It can be installed on very low end computers with under a GiG of drive space, and 32k ram. So stable, a Win 9.x. demo cannot crash it =)). Not used often because many people have no idea it exists (that's changing though).
a good OS for stability.

Completely incomprehensible when in terminal form, comprehensible in graphic form. Users often feel a strange, all-consuming need to write microsoft as "M$" or windows as "Windoze". This behaviour has no been deciphered by psychologists yet, but it is suspected that they do it to "fight the man". Only the faggiest of users use these words, although regular linux users use them too.
Hardcore Linux user: "OMG M$ r releasing teir new windoze version lol BSOD evry 2 mins lol."
Windows user: "...the hell?"

Extremely stable and advanced Operating System. much used by System operators to run on webservers because of it's stability and safety. Very hard to use. Not compatible with Windows programs and therefore not recommended for gamers.
Thank god my servers are much safer and stable now they're penguin powered by Linux

You have two cows.

The city council demands that you disect one of them and allow the town citizens to do whatever they want to it.
The town citizens use genetic modification to enhance choice organs.
They take several days to re-animate the cow, until they finally have a working zombie-cow that produces SuperMilk (similar to Popeye's spinach) but random organs stop every 10 seconds, forcing the people to disect it again just to fix it.

You live happily on your regular milk while the town struggles.
No, this Linux diatribe isn't copypasta.
I'm just as astounded as you.

Linux - free, stable, open-source operating system - and that’s about it.

Not as good as people make it out to be, very undeveloped and bad compatibility weights this OS down.

The reason that Linux does not have as many viruses, trojans, spyware, etc as your precious "Windoze" is because it is not incompatible with these programs - Linux is not popular enough... yet.

"Linux-text-only" was a long time ago noobs, get with the times please.
Most noobs on urbandictionary haven't even gotten past burning their .iso image to a disk - too hard.

I bet they buy an APC magazine with a live-CD and call Linux slow because they don't even understand how RAM swap files work.

I myself prefer UNIX without any kind of GUI.
