Software Hoarding
Copyleft is the legal technique of granting certain freedoms over copies of copyrighted works with the requirement that the same rights be preserved in derivative works. In this sense, ''freedoms'' refers to the use of the work for any purpose, and the ability to modify, copy, share, and redistribute the work, with or without a fee. Licenses which implement copyleft can be used to maintain copyright conditions for works ranging from computer software, to documents, art, scientific discoveries and even certain patents. Copyleft software licenses are considered ''protective'' or ''reciprocal'' in contrast with permissive free software licenses, and require that information necessary for reproducing and modifying the work must be made available to recipients of the software program, which are often distributed as binary executables. This information is most commonly in the form of source code files, which usually contain a copy of the license terms and acknowledge the autho ...

Share-alike
Share-alike (đź„Ž) is a copyright licensing term, originally used by the Creative Commons project, to describe works or licenses that require copies or adaptations of the work to be released under the same or similar license as the original. Copyleft licenses are free content or free software licenses with a share-alike condition. Two currently-supported Creative Commons licenses have the ShareAlike condition: Creative Commons Attribution-ShareAlike (a copyleft, free content license) and Creative Commons Attribution-NonCommercial-ShareAlike (a proprietary license). The term has also been used outside copyright law to refer to a similar plan for patent licensing. Copyleft Copyleft or libre share-alike licenses are the largest subcategory of share-alike licenses. They include both free content licenses like Creative Commons Attribution-ShareAlike and free software licenses like the GNU General Public License. These licenses have been described pejoratively as viral licenses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Principia Discordia
The ''Principia Discordia'' is the first published Discordian religious text. It was written by Greg Hill (Malaclypse the Younger) with Kerry Wendell Thornley (Lord Omar Khayyam Ravenhurst) and others. The first edition was printed allegedly using Jim Garrison's Xerox printer in 1963. The second edition was published under the title ''Principia Discordia or How The West Was Lost'' in a limited edition of five copies in 1965. The phrase ''Principia Discordia'', reminiscent of Isaac Newton's 1687 ''Principia Mathematica'', is presumably intended to mean ''Discordant Principles'', or ''Principles of Discordance''. The ''Principia'' describes the Discordian Society and its Goddess Eris, as well as the basics of the POEE denomination of Discordianism. It features typewritten and handwritten text intermixed with clip art, stamps, and seals appropriated from other sources. While the ''Principia'' is full of literal contradictions and unusual humor, it contains several passages which pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Don Hopkins
Don Hopkins is an artist and programmer specializing in human computer interaction and computer graphics. He is an alumnus of the University of Maryland and a former member of the University of Maryland Human–Computer Interaction Lab. He inspired Richard Stallman, who described him as a "very imaginative fellow", to use the term copyleft. He coined Deep Crack as the name of the EFF DES cracker. He ported the ''SimCity'' computer game to several versions of Unix and developed a multi player version of ''SimCity'' for X11, did much of the core programming of ''The Sims'', and developed robot control and personality simulation software for Will Wright's Stupid Fun Club. He developed and refined pie menus for many platforms and applications including window managers, Emacs, ''SimCity'' and ''The Sims'', and published a frequently cited paper about pie menus at CHI'88 with John Raymond Callahan, Ben Shneiderman and Mark Weiser. He has published many free software and open sour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Software Foundation
The Free Software Foundation (FSF) is a 501(c)#501(c)(3), 501(c)(3) non-profit organization founded by Richard Stallman on October 4, 1985, to support the free software movement, with the organization's preference for software being distributed under copyleft ("share alike") terms, such as with its own GNU General Public License. The FSF was incorporated in Boston, Massachusetts, United States, US, where it is also based. From its founding until the mid-1990s, FSF's funds were mostly used to employ software developers to write free software for the GNU Project. Since the mid-1990s, the FSF's employees and volunteers have mostly worked on legal and structural issues for the free software movement and the free software community. Consistent with its goals, the FSF aims to use only free software on its own computers. History The Free Software Foundation was founded in 1985 as a Nonprofit corporation, non-profit corporation supporting free software development. It continued existi ...

O'Reilly Media
O'Reilly Media (formerly O'Reilly & Associates) is an American learning company established by Tim O'Reilly that publishes books, produces tech conferences, and provides an online learning platform. Its distinctive brand features a woodcut of an animal on many of its book covers. Company Early days The company began in 1978 as a private consulting firm doing technical writing, based in the Cambridge, Massachusetts area. In 1984, it began to retain publishing rights on manuals created for Unix vendors. A few 70-page "Nutshell Handbooks" were well-received, but the focus remained on the consulting business until 1988. After a conference displaying O'Reilly's preliminary Xlib manuals attracted significant attention, the company began increasing production of manuals and books. The original cover art consisted of animal designs developed by Edie Freedman because she thought that Unix program names sounded like "weird animals". Global Network Navigator In 1993 O'Reilly Media creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proprietary Software
Proprietary software is software that is deemed within the free and open-source software to be non-free because its creator, publisher, or other rightsholder or rightsholder partner exercises a legal monopoly afforded by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting his or her freedoms. It is often contrasted with open-source or free software. For this reason, it is also known as non-free software or closed-source software. Types Origin Until the late 1960s computers—large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than sold. Service and all software available were usually supplied by manufacturers without separate charge until 1969. Computer vendors ...
