Debian (/ˈdɛbiən/) is an operating system composed primarily of free and open-source software, most of which is under the GNU General Public License, and developed by a group of individuals known as the Debian project. Debian is one of the most popular Linux distributions for personal computers and network servers, and has been used as a base for several other Linux distributions.

Debian was first announced in 1993 by Ian Murdock, and the first stable release was made in 1996. The development is carried out over the Internet by a team of volunteers guided by a project leader and three foundational documents. New distributions are updated continually, and the next candidate is released after a time-based freeze.

As one of the earliest Linux distributions, it was envisioned that Debian was to be developed openly in the spirit of Linux and GNU. This vision drew the attention and support of the Free Software Foundation, which sponsored the project for the first part of its life.

Features

Debian is primarily a Linux distribution with access to online repositories that contain over 37,500 software packages. Debian officially contains only free software, but non-free software can be downloaded from the Debian repositories and installed. Debian includes popular free programs such as LibreOffice, Iceweasel web browser, Evolution mail, K3b disc burner, VLC media player, GIMP image editor and Evince document viewer. Debian is a popular choice for web servers.

The cost of developing all of the packages included in Debian 5.0 Lenny (323 million lines of code) has been estimated to be about US$ 8 billion, using one method based on the COCOMO model. As of 2014, Ohloh estimates that the codebase (78 million lines of code) would cost about US$ 1.5 billion to develop, using a different method based on the same model.

The current stable release, code-named Wheezy, is officially supported on thirteen architecture ports, introducing s390x and armhf. Notable new features in this release include: multiarch, which allows 32-bit Linux software to run on 64-bit operating system installs; UEFI support for amd64; improved multimedia support, reducing reliance on third-party repositories; compiled packages with hardened security flags; AppArmor, which assists in protecting a system against unknown vulnerabilities; and systemd, which ships as a technology preview.

Kernels

Debian supports two kernels, Linux and kFreeBSD, and offers GNU Hurd unofficially. GNU/kFreeBSD is released as a technology preview for IA-32 and x86-64 architectures, and still lacks the amount of software available in Debian's Linux distributionThere are several flavors of the Linux kernel for each port; for instance, the i386 port has flavors for IA-32 PCs supporting Physical Address Extension and real-time computing, for older PCs, and for x86-64 PCs. The Linux kernel does not officially contain firmware without sources, although such firmware is available in non-free packages and alternative installation media.

LXDE

LXDE is a free desktop environment with comparatively low resource requirements. This makes it especially suitable for resource-constrained personal computers.

LXDE is designed for Unix-like platforms, such as Linux or FreeBSD. The goal of the project is to provide a desktop environment that is fast and energy efficient. LXDE stands for "Lightweight X11 Desktop Environment".

In 2010, tests suggested that LXDE 0.5 had the lowest memory usage of the four most popular desktop environments of the time (GNOME 2.29, KDE Plasma Desktop 4.4, and Xfce 4.6), and that it consumed less energy, which suggests mobile computers with LXDE 0.5 drained their battery at a slower pace than those with other desktop environments.

LXDE is the default desktop environment of Knoppix, Lubuntu, Peppermint Linux OS and Raspbian, among others.

LXDE is written in the C programming language, using the GTK+ toolkit, and runs on Unix and other POSIX compliant platforms, such as Linux and BSD. GTK+ is commonly used in many Linux distributions and allows applications to run on different platforms. LXDE uses rolling releases for the individual components (or group of components with coupled dependencies). Its window manager is Openbox. LXDE includes GPL licensed code as well as LGPL licensed code.
