KDE Software Compilation
The KDE Software Compilation (KDE SC) was an umbrella term for the desktop environment plus a range of included applications produced by KDE. From its 1.0 release in July 1998 until the release of version 4.4 in February 2010, the Software Compilation was simply known as KDE, which stood for K Desktop Environment until the rebrand. The then called KDE SC was used from 4.4 onward until the final release 4.14 in July 2014. It consisted of the KDE Plasma 4 desktop and those KDE applications, whose development teams chose to follow the Software Compilation's release schedule. After that, the KDE SC was split into three separate product entities: KDE Plasma, KDE Frameworks and KDE Applications, each with their own independent release schedules. History Origins KDE was founded in 1996 by Matthias Ettrich, who was then a student at the University of Tübingen. At the time, he was troubled by certain aspects of the Unix desktop. Among his qualms was that none of the application software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KDE Plasma 4
KDE Plasma 4 is the fourth generation of the KDE workspace environments. It consists of three workspaces, each targeting a certain platform: ''Plasma Desktop'' for traditional desktop PCs and Notebook (computer), notebooks, ''Plasma Netbook'' for netbooks, and ''Plasma Active'' for tablet computer, tablet PCs and similar devices. KDE Plasma 4 was released as part of KDE Software Compilation 4 and replaced Kicker (KDE), Kicker, KDesktop, and SuperKaramba, which formed the Desktop in earlier KDE releases. They are bundled as the default environment with a number of free software operating systems, such as Chakra (operating system), Chakra, Kubuntu, Mageia (DVD version), openSUSE, or TrueOS. With the release of KDE SC 4.11 on 14 August 2013, KDE Plasma 4 was placed into a feature freeze and turned into a long-term stable package until August 2015. On 15 July 2014 KDE Plasma 4's successor, KDE Plasma 5, was released. Features Plasma features ''containments'', which are essentially ...

KDE Frameworks
KDE Frameworks is a collection of Library (computing), libraries and software frameworks readily available to any Qt (software), Qt-based software stacks or applications on multiple operating systems. Featuring frequently needed functionality solutions like hardware integration, file format support, additional graphical control elements, plotting functions, and spell checker, spell checking, the collection serves as the technological foundation for KDE Plasma and KDE Applications, KDE Gear. It is distributed under the GNU Lesser General Public License (LGPL). Overview KDE Frameworks is based on Qt, which enables a more widespread use of QML, a simpler JavaScript-based declarative programming language, for the design of user interfaces. The graphics rendering engine used by QML allows for more fluid user interfaces across different devices. Since the split of the KDE Software Compilation into KDE Frameworks 5, KDE Plasma 5 and KDE Applications, each sub-project can pick its ow ...

Proprietary Software
Proprietary software is computer software, software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly 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 their freedoms. Proprietary software is a subset of non-free software, a term defined in contrast to free and open-source software; non-commercial licenses such as CC BY-NC are not deemed proprietary, but are non-free. Proprietary software may either be closed-source software or source-available software. Types Origin Until the late 1960s, computers—especially large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than Sales, sold. Service and all software available ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU General Public License
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domai ...

Q Public License
The Q Public License (QPL) is a non-copyleft license, created by the company Trolltech for its free software edition of the Qt toolkit and framework. It was used until Qt 3.0, until version 4.0 was released under the Free Software Foundation's (FSF) GNU General Public License (GPL) version 2. It fails the Debian Free Software Guidelines, used by several Linux distributions, though it qualifies for the FSF's Free Software Definition; however, it is incompatible with the FSF's GPL, meaning that products derived from code under both the GPL and the QPL cannot be redistributed. History KDE, a desktop environment for Linux, is based on Qt. Only the free open source edition of Qt was covered by the QPL; the commercial edition, which is functionally equal, is under a pay-per-use license and could not be freely distributed. Meanwhile, the Free Software Foundation and authors of the GPL objected to the QPL as it was a non-copyleft license incompatible with the GPL. As KDE grew in po ...

Open Source License
Open-source licenses are software licenses that allow content to be used, modified, and shared. They facilitate free and open-source software (FOSS) development. Intellectual property (IP) laws restrict the modification and sharing of creative works. Free and open-source licenses use these existing legal structures for an inverse purpose. They grant the recipient the rights to use the software, examine the source code, modify it, and distribute the modifications. These criteria are outlined in the Open Source Definition. After 1980, the United States began to treat software as a literary work covered by copyright law. Richard Stallman founded the free software movement in response to the rise of proprietary software. The term "open source" was used by the Open Source Initiative (OSI), founded by free software developers Bruce Perens and Eric S. Raymond. "Open source" emphasizes the strengths of the open development model rather than software freedoms. While the goals behind t ...

Usenet
Usenet (), a portmanteau of User's Network, is a worldwide distributed discussion system available on computers. It was developed from the general-purpose UUCP, Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis (computing), Jim Ellis conceived the idea in 1979, and it was established in 1980.''From Usenet to CoWebs: interacting with social information spaces'', Christopher Lueg, Danyel Fisher, Springer (2003), , Users read and post messages (called ''articles'' or ''posts'', and collectively termed ''news'') to one or more topic categories, known as Usenet newsgroup, newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are Threaded discussion, threaded, as with web forums and BBSes, though posts are stored on the server sequentially.

Application Software
Application software is any computer program that is intended for end-user use not operating, administering or programming the computer. An application (app, application program, software application) is any program that can be categorized as application software. Common types of applications include word processor, media player and accounting software. The term ''application software'' refers to all applications collectively and can be used to differentiate from system and utility software. Applications may be bundled with the computer and its system software or published separately. Applications may be proprietary or open-source. The short term ''app'' (coined in 1981 or earlier) became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with introduction of the Mac App Store (in 2010) and Windows Store (in 2011), the term was extended in popular use to include desktop a ...

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...
