99-446: A force, right? We just unified electro-weak, ok? The grand unified field theory still escapes us until the document licences too are just additional permissions on top of GPL. I don't know how we'll ever get there, that's gravity, it's really hard. The GNU FDL requires that licensees, when printing a document covered by the license, must also include "this License, the copyright notices, and the license notice saying this License applies to
132-535: A further development of the Lavochkin La-126 prototype. The first prototype, designated La-130 was finished in 1946. Similarity to the famous Lavochkin La-7 was only superficial – the new fighter had an all-metal construction and a laminar flow wing. Weight savings due to elimination of wood from the airframe allowed for greatly improved fuel capacity and four-cannon armament. Mock combat demonstrated that
165-518: A licensee is not allowed to save document copies "made" in a proprietary file format or using encryption. In 2003, Richard Stallman said about the above sentence on the debian-legal mailing list: This means that you cannot publish them under DRM systems to restrict the possessors of the copies. It isn't supposed to refer to use of encryption or file access control on your own copy. I will talk with our lawyer and see if that sentence needs to be clarified. A GNU FDL work can quickly be encumbered because
198-470: A new, different title must be given and a list of previous titles must be kept. This could lead to the situation where there are a whole series of title pages, and dedications, in each and every copy of the book if it has a long lineage. These pages cannot be removed until the work enters the public domain after copyright expires. Richard Stallman said about invariant sections on the debian-legal mailing list: The goal of invariant sections, ever since
231-510: A work and requires all copies and derivatives to be available under the same license. Copies may also be sold commercially, but, if produced in larger quantities (greater than 100), the original document or source code must be made available to the work's recipient. The GFDL was designed for manuals , textbooks, other reference and instructional materials, and documentation which often accompanies GNU software. However, it can be used for any text-based work, regardless of subject matter. For example,
264-594: The Debian project, Thomas Bushnell , Nathanael Nerode, and Bruce Perens have raised objections. Bruce Perens saw the GFDL even outside the "Free Software ethos": "FSF, a Free Software organization, isn't being entirely true to the Free Software ethos while it is promoting a license that allows invariant sections to be applied to anything but the license text and attribution. [...] the GFDL isn't consistent with
297-694: The V-1 flying bomb , probably taken from surplus Luftwaffe stocks) under each wing. The 70 km/h (45 mph) increase in top speed came at the expense of tremendous noise and vibration. The engines were unreliable and worsened the handling. The project was abandoned although between 3 and 9 La-9RD were reported to perform at airshows, no doubt pleasing the crowds with the noise. Other notable La-9 variants were: Data from General characteristics Performance Armament Related development Aircraft of comparable role, configuration, and era Related lists The initial version of this article
330-535: The 80s when we first made the GNU Manifesto an invariant section in the Emacs Manual, was to make sure they could not be removed. Specifically, to make sure that distributors of Emacs that also distribute non-free software could not remove the statements of our philosophy, which they might think of doing because those statements criticize their actions. The GNU FDL is incompatible in both directions with
363-487: The Document in any medium, either commercially or noncommercially" and therefore is incompatible with material that excludes commercial re-use. As mentioned above, the GFDL was designed with commercial publishers in mind, as Stallman explained: The GFDL is meant as a way to enlist commercial publishers in funding free documentation without surrendering any vital liberty. The 'cover text' feature, and certain other aspects of
SECTION 10
#1732783579085396-483: The Document itself is wholly editable and is essentially covered by a license equivalent to (but mutually incompatible with) the GNU General Public License , some of the secondary sections have various restrictions designed primarily to deal with proper attribution to previous authors. Specifically, the authors of prior versions have to be acknowledged and certain "invariant sections" specified by
429-458: The Document". This means that if a licensee prints out a copy of an article whose text is covered under the GNU FDL, they must also include a copyright notice and a physical printout of the GNU FDL, which is a significantly large document in itself. Worse, the same is required for the standalone use of just one (for example, Misplaced Pages) image. Several Wikimedia projects have over the years abandoned
462-595: The GFDL if such fair use is covered by all potential subsequent uses. One example of such liberal and commercial fair use is parody . Although the two licenses work on similar copyleft principles, the GFDL is not compatible with the Creative Commons Attribution-ShareAlike license . However, at the request of the Wikimedia Foundation , version 1.3 added a time-limited section allowing specific types of websites using
495-455: The GFDL to additionally offer their work under the CC BY-SA license. These exemptions allow a GFDL-based collaborative project with multiple authors to transition to the CC BY-SA 3.0 license, without first obtaining the permission of every author, if the work satisfies several conditions: To prevent the clause from being used as a general compatibility measure, the license itself only allowed
528-482: The GFDL. In the case of Baidu, Misplaced Pages representatives asked the site and its contributors to respect the terms of the licenses and to make proper attributions. Some critics consider the GFDL a non-free license. Some reasons for this are that the GFDL allows "invariant" text which cannot be modified or removed, and that its prohibition against digital rights management (DRM) systems applies to valid usages, like for "private copies made and not distributed". Notably,
561-645: The GPL—material under the GNU FDL cannot be put into GPL code and GPL code cannot be put into a GNU FDL manual. At the June 22–23, 2006 international GPLv3 conference in Barcelona, Eben Moglen hinted that a future version of the GPL could be made suitable for documentation: By expressing LGPL as just an additional permission on top of GPL we simplify our licensing landscape drastically. It's like for physics getting rid of
594-597: The La-130 was evenly matched with the La-7 but was inferior to the Yakovlev Yak-3 in horizontal planes. The new fighter, officially designated La-9, entered production in August 1946. A total of 1,559 aircraft were built by the end of production in 1948 . Like other aircraft designers at the time, Lavochkin was experimenting with using jet propulsion to augment performance of piston-engined fighters. One such attempt
627-478: The Wikimedia Foundation to migrate the projects to the similar Creative Commons Attribution Share-Alike (CC BY-SA) license. These changes were implemented on version 1.3 of the license, which includes a new provision allowing certain materials released under the (GFDL) license to be used under a Creative Commons Attribution Share-Alike license also. Material licensed under the current version of
660-519: The change to occur before August 1, 2009. At the release of version 1.3, the FSF stated that all content added before November 1, 2008, to Misplaced Pages as an example satisfied the conditions. The Wikimedia Foundation itself after a public referendum, invoked this process to dual-license content released under the GFDL under the CC BY-SA license in June 2009, and adopted a foundation-wide attribution policy for
693-451: The ethos that FSF has promoted for 19 years." In 2006, Debian developers voted to consider works licensed under the GFDL to comply with their Debian Free Software Guidelines provided that the invariant section clauses are not used. However, their resolution stated that even without invariant sections, GFDL-licensed software documentation is considered to be "still not free of trouble" by the project, namely because of its incompatibility with
SECTION 20
#1732783579085726-418: The fact that the GFDL "does not allow for easy duplication and modification", especially for digital documentation. The GNU FDL contains the statement: You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. A criticism of this language is that it is too broad, because it applies to private copies made but not distributed. This means that
759-845: The free online encyclopedia Misplaced Pages uses the GFDL (coupled with the Creative Commons Attribution Share-Alike License ) for much of its text, excluding text that was imported from other sources after the 2009 licensing update that is only available under the Creative Commons license. The GFDL was released in draft form for feedback in September 1999. After revisions, version 1.1 was issued in March 2000, version 1.2 in November 2002, and version 1.3 in November 2008. The current state of
792-426: The license can be used for any purpose, as long as the use meets certain conditions. The license explicitly separates any kind of "Document" from "Secondary Sections", which may not be integrated with the Document, but exist as front-matter materials or appendices. Secondary sections can contain information regarding the author's or publisher's relationship to the subject matter, but not any subject matter itself. While
825-567: The license is version 1.3. On December 1, 2007, Misplaced Pages founder Jimmy Wales announced that a long period of discussion and negotiation between and amongst the Free Software Foundation, Creative Commons, the Wikimedia Foundation and others had produced a proposal supported by both the FSF and Creative Commons to modify the Free Documentation License in such a fashion as to allow the possibility for
858-411: The license more financially attractive to commercial publishers of software documentation, some of whom were consulted during the drafting of the GFDL. "Endorsements" sections are intended to be used in official standard documents, where the distribution of modified versions should only be permitted if they are not labeled as that standard anymore. The GFDL requires the ability to "copy and distribute
891-487: The license that deal with covers, title page, history, and endorsements, are included to make the license appealing to commercial publishers for books whose authors are paid. Material that restricts commercial re-use is incompatible with the license and cannot be incorporated into the work. However, incorporating such restricted material may be fair use under United States copyright law (or fair dealing in some other countries) and does not need to be licensed to fall within
924-522: The major free software licenses. Those opposed to the GFDL have recommended the use of alternative licenses such as the BSD License or the GNU GPL. The FLOSS Manuals foundation, an organization devoted to creating manuals for free software, decided to eschew the GFDL in favor of the GPL for its texts in 2007, citing the incompatibility between the two, difficulties in implementing the GFDL, and
957-442: The original author and dealing with his or her relationship to the subject matter may not be changed. If the material is modified, its title has to be changed (unless the prior authors permit to retain the title). The license also has provisions for the handling of front-cover and back-cover texts of books, as well as for "History", "Acknowledgements", "Dedications" and "Endorsements" sections. These features were added in part to make

1023-475: The use of content from Wikimedia Foundation projects. There have currently been no cases involving the GFDL in a court of law, although its sister license for software, the GNU General Public License , has been successfully enforced in such a setting. Although the content of Misplaced Pages has been plagiarized and used in violation of the GFDL by other sites, such as Baidu Baike , no contributors have ever tried to bring an organization to court due to violation of

A more unusual approach was La-9RD which was tested in 1947–1948. It was a production La-9 with a reinforced airframe and armament reduced to two cannons, which carried a single RD-13 pulsejet (the engine which powered
