What is the general public license?
In September 1983, Freedom activist Richard Stallman, then MIT, a GNU project (expressed Gee-Noo). The idea of GNU was to create a storage of operating systems and software programs freely available for all. Unlike restrictive copyright protection, the Stallman's Copyleft license or general public licenses (GPL), determines how GNU software can be used and distributed. The most basic principles are that the GNU software code and any derivatives and software are freely available and that users can freely edit the code.
Two years after the GNU project, Stallman launched the free software Foundation (FSF) to support the GNU movement and enforced the conditions of a wide public license. Over time, GPL has gone through three revisions, while GPLV3 has been up to date since June 2007. Most open source software uses GPL today, although Stallman, a sticker for terminology, does not use the term "open source" but "freedom softerware" or "free software"Mumerus causes the values of freedom for the user, the cornerstone of its sociopolitical activism.
In addition to a wide public license, FSF also published three other licenses: GNU Smaller Public License (LGPL), GNU (GFDL) documentation and GNU AFFERO (GAGPL). These licenses are used in specific situations where other circumstances require GPL. For example, LGPL is used when software software connects software software with copyright or proprietary software.
The first operating system created through the GNU project, properly named "GNU", was merged with the independent work performed in 1991 by the Finnish American Linus Torvalds, resulting in the Linux core. Dozens of GNU/Linux operating systems are now available in various flavors and types from desktop systems to portable systems suitable for bootable memory rodsky or live CD. The GNU/Linux or "distribution" operating systems, which are short for distributions, are protected from copyright restrictions according to the general public license Copyleft.
6 Most GNU/Linux distributions come up with the software installed to perform everything from tables to text processing, from e -mail to surfing, from music to video editing and photos. Virtually anything that can be done in proprietary operating systems can be done in the GNU system, although there are usually fewer programs in each software category that you can choose in connection with Windows software.While GNU software is generally free, nominal fees are sometimes charged if it requires a CD program or purchases a retail box package. Usually there is a way to get a free program in digital form, through binary files, torrents or other forms of file sharing.
Stallman remains an open and reserved supporter of free software, which promotes the GNU project and a wide public license at the international level. One success includes the reception of GNU/Linux from 2006 in 12,500 schools in India.
