Debian () is a computer operating system composed of software packages released as free and open source software primarily under the GNU General Public License along with other free software licenses.

Debian GNU / Linux, which includes the GNU OS tools and Linux kernel, is a popular and influential Linux distribution.

Debian GNU / Hurd is the Debian project's distribution of the GNU operating system, using the GNU Hurd microkernel.

Debian GNU / Hurd has been in development since 1998, but still has not been officially released.

Over 70 % of the software packaged for Debian GNU / Linux has been ported to the GNU Hurd.

The overwhelming majority of Debian users run Debian GNU / Linux, rather than Debian GNU / Hurd.

The Debian GNU / Hurd developers are hoping to be able to release it for the next major release of Debian, " wheezy ", which is planned to be sometime around 2013.

Debian GNU / Hurd is distributed on a live CD.

The current version of Debian GNU / Hurd is L1 as of 2011.

Thus, the Debian Project is an independent decentralized organization ; it is not backed by a company like Linux distributions such as Ubuntu, openSUSE, Fedora, and Mandriva.

Debian was one of the earlier Linux distributions to compose itself from packages, and robust package management is perhaps Debian's most prominent feature.

Operating systems that supported Alpha included OpenVMS ( previously known as OpenVMS AXP ), Tru64 UNIX ( previously known as DEC OSF / 1 AXP and Digital UNIX ), Windows NT ( until 4. 0 SP6 and Windows 2000 RC1 ), GNU / Linux ( Debian GNU / Linux, Gentoo Linux and Red Hat Linux ), BSD UNIX ( NetBSD, OpenBSD and FreeBSD up to 6. x ), as well as the L4Ka :: Pistachio kernel.

It was useful enough to be picked up by popular Linux distributions, e. g. Debian.

Even after development ceased in September 2008 the browser remained popular and in December 2011 was still available in some Linux distribution's repositories, such as Debian 6 Squeeze, although it will not be part of Debian 7 Wheezy.

Ian Murdock ( born April 28, 1973 ) is the founder of the Debian distribution and Progeny Linux Systems, a commercial Linux company.

Both Red Hat and Microsoft announced plans to drop Itanium support in their operating systems due to lack of market interest ; although, other Linux distributions such as Debian remain available for Itanium.

One can distinguish between commercially backed distributions, such as Fedora ( Red Hat ), openSUSE ( Novell ), Ubuntu ( Canonical Ltd .), and Mandriva Linux ( Mandriva ), and entirely community-driven distributions, such as Debian, Mageia and Gentoo.

Maatkit is included with several GNU / Linux distributions such as CentOS and Debian and packages are available for Fedora and Ubuntu as well.

By 2000, most large-scale ( Mach-like ) efforts had ended, although OpenStep used an adapted Mach kernel called XNU, which is now used in the OS known as Darwin, which is the open source part of Mac OS X .. As of 2012, the Mach-based GNU Hurd is also functional and its inclusion in testing versions of Arch Linux and Debian in progress.

Their Platform Services technology supported both Debian and RPM-based distributions for Linux platforms.

Progeny Componentized Linux, usually called Progeny Debian, is a defunct free operating system.

Progeny Debian aimed to be a model for developing a component-based Linux.

In August 2011, the ARM-based Raspberry Pi credit card-sized computer was shown running a specially compiled ARM version of Quake III on the Debian Linux Operating System.

Libranet attempted to carve a niche in the Linux distro market as the user-friendly distro, with extensive support ( termed " up and running support "), that, of all the desktop distros, was the most compatible with the actual Debian release ( at this time, Woody ).

NetZero has versions of its proprietary dial-up software for computers running Mac OS 9 or Mac OS X. NetZero previously offered a Linux version of the NetZero software advertised as being for Linspire, however the software could be installed on any Debian-based i386 or x86-64 Linux distribution ; NetZero can also be installed on any RPM-based Linux distribution as long as Alien is used to convert the NetZero Debian package into an RPM package.

Many GNU / Linux distributions do not contain libdvdcss ( for example Debian, Fedora, SUSE Linux, and Ubuntu ) due to fears of running afoul of DMCA-style laws, however they may provide the tools to let the user install it themselves.

DreamHost's shared and dedicated hosting network consists of Apache, nginx and lighttpd web servers running on the Debian GNU / Linux operating system.

; Debian: OpenOffice. org running on Maemo 5 using Easy Debian. The complete ARM Debian distribution can be installed as a Maemo application, making thousands of software packages available ( including OpenOffice. org, Mozilla Firefox, Java, the GNOME and LXDE desktops, etc .).

Debian can be used on a variety of hardware, from laptops and desktops to NAS devices, phones, and servers.

The Debian project, among others, have worked on the Hurd project to produce binary distributions of Hurd-based GNU operating systems for IBM PC compatible systems.

Initially it is impossible to find any mention of specific bugs on Microsoft's website, but later he notices that Microsoft has instated a system similar to the Debian one, though sugar-coated so as to not ruin the vision demanded by its customers.

In the same way, the Debian project has its own criteria, the Debian Free Software Guidelines, on which the Open-Source Definition is based.

The definition was based on the Debian Free Software Guidelines, written and adapted primarily by Bruce Perens.

The group adopted the Open Source Definition for open-source software, based on the Debian Free Software Guidelines.

The added clause to the license was based on the original BSD license's advertising clause, which was viewed by the Free Software Foundation and Debian as incompatible with the GNU General Public License.

Some projects made releases ( notably OpenBSD 3. 5 and 3. 6, and Debian 3. 1 " Sarge ") based on XFree86 version 4. 4 RC2, the last version under the old license.

The OSI Open Source Definition and the Debian Free Software Guidelines specifically allow for restrictions on distribution of modified source code, given explicit permission to distribute both patches and source code.

Linspire was based on Debian ( and later Ubuntu ) with a KDE interface.

Exim 4 is currently the default MTA on Debian GNU / Linux systems.

Because the Debian approach diverges significantly from the Exim one it is common to find a lack of support for the Debian approach on the regular Exim mailing-lists and users are pointed towards the Debian-specific list.

Ash has since been replaced on both Debian and Ubuntu.

The Advanced Packaging Tool, or APT, is a free user interface that works with core libraries to handle the installation and removal of software on the Debian GNU / Linux distribution and its variants.

Libranet was an operating system based on Debian GNU / Linux.

The Debian GNU / Linux package tool apt-get has an Easter egg involving an ASCII cow when variants on are typed into the shell.
