KJS is KDE's JavaScript engine that was originally developed for the KDE project's Konqueror web browser by Harri Porten in 2000.
On June 13, 2002, Maciej Stachowiak announced on a mailing list that Apple was releasing JavaScriptCore, a framework for Mac OS X that was based on KJS. [2]
Konqueror is a free and open-source web browser and file manager that provides web access and file-viewer functionality for file systems. It forms a core part of the KDE Software Compilation. Developed by volunteers, Konqueror can run on most Unix-like operating systems. The KDE community licenses and distributes Konqueror under GNU GPL-2.0-or-later.
Qt is cross-platform application development framework for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed.
A browser engine is a core software component of every major web browser. The primary job of a browser engine is to transform HTML documents and other resources of a web page into an interactive visual representation on a user's device.
KHTML is a discontinued browser engine that was developed by the KDE project. It originated as the engine of the Konqueror browser in the late 1990s, but active development ceased in 2016. It was officially discontinued in 2023.
KDevelop is a free and open-source integrated development environment (IDE) for Unix-like computer operating systems and Windows. It provides editing, navigation and debugging features for several programming languages, and integration with build automation and version-control systems, using a plugin-based architecture.
Yahoo Widgets is a discontinued free application platform for Mac OS X and Microsoft Windows, specifically Windows XP, Vista and Windows 7. The software was previously called Konfabulator, but after being acquired by computer services company Yahoo on July 25, 2005, it was rebranded. The name Konfabulator was subsequently reinstated as the name of the underlying rendering engine. The engine uses a JavaScript runtime environment combined with an XML interpreter to run small applications referred to as widgets, and hence is part of a class of software applications called widget engines. On February 27, 2012, Yahoo updated the License agreement stating that as of April 3, 2012 Yahoo! Widgets will continue to be available for download but support and development would stop.
Harri Porten is a software engineer. Porten, a KDE developer and former Trolltech employee, is the CEO of Froglogic, a consultancy company related to Qt development. He lives in Hamburg, Germany.
WebKit is a browser engine developed by Apple and primarily used in its Safari web browser, as well as all web browsers on iOS and iPadOS. WebKit is also used by the PlayStation consoles starting with the PS3, the Tizen mobile operating systems, the Amazon Kindle e-book reader, Nintendo consoles starting with the 3DS Internet Browser, and the discontinued BlackBerry Browser.
Darin Adler is a senior engineering manager for Apple and a frequent speaker at Apple's Worldwide Developers Conference and Stump the Experts panelist.
A JavaScript engine is a software component that executes JavaScript code. The first JavaScript engines were mere interpreters, but all relevant modern engines use just-in-time compilation for improved performance.
KDE Software Compilation 4 was the only series of the so-called KDE Software Compilation, first released in January 2008 and the last release being 4.14.3 released in November 2014. It was the follow-up to K Desktop Environment 3. Following KDE SC 4, the compilation was broken up into basic framework libraries, desktop environment and applications, which are termed KDE Frameworks 5, KDE Plasma 5 and KDE Applications, respectively.
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 notebooks, Plasma Netbook for netbooks, and Plasma Active for tablet PCs and similar devices.
Kross is a scripting framework for KDE Frameworks. Originally Kross was designed for use in KOffice but eventually became the official scripting framework in KDE Software Compilation 4. Kross is designed to provide full scripting power for users of KDE applications, with a language of their own choice; and make it easy for developers targeting the KDE platform to enable their application with support for multiple scripting languages.
Maciej Stachowiak is a Polish American software developer currently employed by Apple Inc., where he is a leader of the development team responsible for the WebKit Framework. A longtime proponent of open source software, Stachowiak was involved with the SCWM, GNOME and Nautilus projects for Linux before joining Apple. He is actively involved the development of web standards, served as a co-chair of the World Wide Web Consortium's HTML 5 working group and was a member of the Web Hypertext Application Technology Working Group steering committee.
Titanium SDK is an open-source framework that allows the creation of native mobile applications on platforms iOS and Android from a single JavaScript codebase. It is presently developed by non-profit software foundation TiDev, Inc.
The KDE Software Compilation 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.
A browser speed test is a computer benchmark that scores the performance of a web browser, by measuring the browser's efficiency in completing a predefined list of tasks. In general the testing software is available online, located on a website, where different algorithms are loaded and performed in the browser client. Typical test tasks are rendering and animation, DOM transformations, string operations, mathematical calculations, sorting algorithms, graphic performance tests and memory instructions. Browser speed tests have been used during browser wars to prove superiority of specific web browsers. The popular Acid3 test is no particular speed test but checks browser conformity to web standards.
KDE Frameworks is a collection of libraries and software frameworks readily available to any 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 checking, the collection serves as the technological foundation for KDE Plasma and KDE Gear. It is distributed under the GNU Lesser General Public License (LGPL).
KDE Projects are projects maintained by the KDE community, a group of people developing and advocating free software for everyday use, for example KDE Plasma and KDE Frameworks or applications such as Amarok, Krita or Digikam. There are also non-coding projects like designing the Breeze desktop theme and iconset, which is coordinated by KDE's Visual Design Group. Even non-Qt applications like GCompris, which started as a GTK-based application, or web-based projects like WikiToLearn are officially part of KDE.
