Debian is a free, open source Linux distribution. It was initially launched by Ian Murdock in 1993 as the “Debian Linux Release”. It was the first distribution to be open for contribution to all users and developers.
The Debian GNU/Linux distribution includes the Linux kernel or the FreeBSD kernel, and thousands of prepackaged applications. Moreover, its developers are also working on providing Debian for other kernels, such as GNU Hurd.
Out of curiosity, releases are named after characters of the Toy Story movies. The current version of the distribution is Debian 11, known as Bullseye, the toy horse.
The distro is available under several licenses: BSD, GPL and other open licenses.
The Debian Project
The Debian Project is the community of developers and users in charge of developing and maintaining the distribution. Their goal is to build a distribution fully composed of free software. In fact, Debian is the biggest Linux distribution independent from any commercial entity. The current leader of the Debian Project is Jonathan Carter, since April 2020.
The project has also created a contract to collect a set of principles and commitments: The Debian Social Contract. The current version of the contract, 1.1, was ratified in April 2004. It establishes, for instance, that the distribution will always remain 100% free and that all problems and bugs will be publicly reported.
It is worth noting that the Debian Free Software Guidelines have been widely adopted by the free software community; becoming the foundation for the Open Source Definition.
