You can find hereafter a list of the sites providing more detailed information concerning the Free Culture (in general) and the Free Software (in particular).
The Free Software Foundation (FSF) is a nonprofit with a worldwide mission to promote computer user freedom. We defend the rights of all software users.
Free software developers guarantee everyone equal rights to their programs; any user can study the source code, modify it, and share the program. By contrast, most software carries fine print that denies users these basic rights, leaving them susceptible to the whims of its owners and vulnerable to surveillance.
Philosophy of the GNU Project:
Free software means that the software's users have freedom. (The issue is not about price.) We developed the GNU operating system so that users can have freedom in their computing.
Specifically, free software means users have the four essential freedoms: (0) to run the program, (1) to study and change the program in source code form, (2) to redistribute exact copies, and (3) to distribute modified versions.
Software differs from material objects—such as chairs, sandwiches, and gasoline—in that it can be copied and changed much more easily. These facilities are why software is useful; we believe a program's users should be free to take advantage of them, not solely its developer.
The Linux Foundation partners with the world's leading developers and companies to solve the hardest technology problems and accelerate open technology development and commercial adoption.
Founded in 2000, The Linux Foundation today provides tools, training, and events to scale any open source project, which together deliver an economic impact not achievable by any one company.
The Wikimedia Foundation is a global movement whose mission is to bring free educational content to the world. Quoting the foundation home page :
"Imagine a world in which every single human being can freely share in the sum of all knowledge. That’s our commitment.". https://wikimediafoundation.org/wiki/Home
Wikipedia is an universal, multilingual encyclopedia, written and maintained by volunteers on the Internet, and functioning under the Wiki principle.
Wikimedia Commons, which is often refereed to as Commons, is a media file repository making available public domain and freely-licensed educational media content (images, sound and video clips) to everyone, in their own language.
Wikitionary was initially designed as the lexical companion to Wikipedia, the encyclopedia project, Wiktionary has grown beyond a standard dictionary and now includes a thesaurus, a rhyme guide, phrase books, language statistics and extensive appendices. We aim to include not only the definition of a word, but also enough information to really understand it. Thus etymologies, pronunciations, sample quotations, synonyms, antonyms and translations are included.
The Wikiquote collaborative project, is a free online compendium of sourced quotations from notable people and creative works in every language, translations of non-English quotes, and links to Wikipedia for further information.
Wikisource is a project to create a growing free content library of source texts, as well as translations of source texts in any language. This work is done by voluntary contributors.
Some things Wikisource includes are: Source texts previously published by any author, Translations of original texts, Historical documents of national or international interest, Bibliographies of authors whose works are in Wikisource.
Some basic criteria for texts excluded from Wikisource are: Copyright infringements, Original writings by a contributor to the project, Mathematical data, formulae, and tables, Source code (for computers), Statistical source data (such as election results).
Unless otherwise noted, all user contributions to Wikisource are released under the Creative Commons Attribution/Share-Alike License (CC-BY-SA) (replacing the previously used GNU Free Documentation License).
Simply, Wikibooks1) is a collection of open-content textbooks. Wikibooks is for textbooks, annotated texts, instructional guides, and manuals. These materials can be used in a traditional classroom, an accredited or respected institution, a home-school environment, as part of a Wikiversity course, or for self-learning.
Wikijunior produces non-fiction books for children from birth to age twelve. These books could take the form of macropedias, textbooks, or primers. These Wikijunior books are written with children in mind. The subjects of these books are chosen because they are appealing to kids. These books are richly illustrated with photographs, diagrams, sketches, and original drawings.
Vikidia is an English encyclopedic project, based on wiki technology, for 8-13 year-old readers and contributors, but not only.
The website is independent from Wikimedia Foundation which owns Wikipedia. It was launched in November 2006 in French and in 2013 in English. Vikidia is handled by the Association Vikidia, a non-profit-organization located in France.
Wikiversity is a Wikimedia Foundation project devoted to learning resources, learning projects, and research for use in all levels, types, and styles of education from pre-school to university, including professional training and informal learning.
Teachers, students, and researchers are invited to join Wikiversity in creating open educational resources and collaborative learning communities.
Wikispecies is a wiki-based on-line project supported by the Wikimedia Foundation. Its aim is to create a comprehensive free content catalog of all species; the project is directed at scientists, rather than at the general public. Wikispecies is available under the GNU Free Documentation License and CC BY-SA 3.0.
Wikivoyage is a free web-based travel guide for travel destinations and travel topics written by volunteer authors ("Wiki-travelers" from all around the world). It is a sister project of Wikipedia and supported and hosted by the same non-profit Wikimedia Foundation. Wikivoyage has been called the "Wikipedia of travel guides".
Wikinews is a free-content news source Wiki and a project of the Wikimedia Foundation. The site works through collaborative journalism. Wikipedia co-founder Jimmy Wales has distinguished Wikinews from Wikipedia by saying "on Wikinews, each story is to be written as a news story as opposed to an encyclopedia article." The neutral point of view policy espoused in Wikinews distinguishes it from other citizen journalism efforts. In contrast to most projects of the Wikimedia Foundation, Wikinews allows original work under the form of original reporting and interviews.
Wikidata is a collaboratively edited knowledge base operated by the Wikimedia Foundation. It is intended to provide a common source of data which can be used by Wikimedia projects such as Wikipedia, and by anyone else, under a public domain license. This is similar to the way Wikimedia Commons provides storage for media files and access to those files for all Wikimedia projects, and which are also freely available for reuse. Wikidata is powered by the software Wikibase.
This project was launched by Wikimedia Deutschland. It was presented during the Semantic Tech & Business Conference in February 2012, and the site was open to the first contributions on 30 October 2012.
Meta (or Wikimedia's Meta-Wiki) is a wiki-based web site that is auxiliary for coordination of all the Wikimedia Foundation projects.
Meta currently serves as one of the major avenues of discussion for Wikimedians including Wikipedians, the others being the mailing lists, the IRC channels, and the talk pages of individual articles and users. Meta is an independent and autonomous project from the English language Wikipedia and thus has its own policies and customs, which often differ from those here.
Originally focused on the English language version of Wikipedia, Meta has, since its upgrade to Wikipedia's custom MediaWiki software, become a multilingual discussion forum used by all Wikimedia language communities.
The Wikimedia Incubator founded on 2 June 2006, is a wiki-based website hosted by the Wikimedia Foundation. It serves as a platform where anyone can build up a community in a certain language edition of a Wikimedia project (Wikipedia, Wiktionary, Wikibooks, Wikinews, Wikiquote and Wikivoyage) that does not yet have its own sub-domain, provided that it is a recognized language.
This is where potential Wikimedia project Wikis in new language versions can be arranged, written, tested and proven worthy of being hosted by the Wikimedia Foundation.
MediaWiki2) is free server-based software, licensed under the GNU General Public License (GPL). It's designed to run on a large server farm for a website that gets millions of hits per day.
By the way, Debian provides more than a pure OS: it comes with over 43000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
Debian is also a democratic community organization, which aims at the development of operating systems exclusively based on free software.
Emmabuntüs3) is a distribution designed to facilitate the refurbishing of computers given to humanitarian associations, in particular the Emmaüs community 4) (hence, the name of the distribution), to help the discovery of the GNU/Linux world by beginners, and limit the the electronic wastes generated by the hardware overconsumption, by extending the lifespan of aging computers.
This page lists the GNU/Linux distributions that are entirely free as in freedom.
The Free Software Foundation seems quite tough in what concerns the real freedom … But can we put the blame on an organization which is seeking a situation that should be commonplace. https://www.gnu.org/distros/free-distros.en.html
h.node : This project aims at the construction of a hardware database in order to identify what devices work with a fully free operating system. The h-node.org website is structured like a Wiki in which all the users can modify or insert new contents. The h-node project is developed in collaboration and as an activity of the Free Software Foundation (FSF).
