A Linux distribution is an operating system made from a software collection, which is based upon the Linux kernel and, often, a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems ranging from embedded devices and personal computers to powerful supercomputers.
Qt is a free and open-source widget toolkit 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. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt. Qt is available under both commercial licenses and open source GPL 2.0, GPL 3.0, and LGPL 3.0 licenses.
The Qt Company is a software company based in Espoo, Finland. It oversees the development of its Qt application framework within the Qt Project. It was formed following the acquisition of Qt by Digia, but was later spun off into a separate, publicly traded company.
Qt Extended is an application platform for embedded Linux-based mobile computing devices such as personal digital assistants, video projectors and mobile phones. It was developed by Qt Software, a subsidiary of Nokia, and when they cancelled the Qt Extended project, as it was free software, the community created a fork of it, the Qt Extended Improved project, and continued building. The QtMoko Debian-based distribution is the natural successor to these projects as continued by the efforts of the Openmoko community.
The Motorola A760 is a Linux-based camera equipped mobile telephone developed at Motorola's laboratory in China and released in the Chinese market on February 16, 2003. The particular Linux distribution used was MontaVista Linux. It is the first phone to use Linux.
Operating systems based on the Linux kernel are used in embedded systems such as consumer electronics.
Linux-based devices or Linux devices are computer appliances that are powered by the Linux kernel and possibly parts of the GNU operating system. Device manufacturers' reasons to use Linux may be various: low cost, security, stability, scalability or customizability. Many original equipment manufacturers use free and open source software to brand their products. Community maintained Linux devices are also available.
Lazarus is a free cross-platform visual integrated development environment (IDE) for rapid application development (RAD) using the Free Pascal compiler.
OpenEmbedded is a build automation framework and cross-compile environment used to create Linux distributions for embedded devices. The OpenEmbedded framework is developed by the OpenEmbedded community, which was formally established in 2003. OpenEmbedded is the recommended build system of the Yocto Project, which is a Linux Foundation workgroup that assists commercial companies in the development of Linux-based systems for embedded products.
A free and open-source graphics device driver is a software stack which controls computer-graphics hardware and supports graphics-rendering application programming interfaces (APIs) and is released under a free and open-source software license. Graphics device drivers are written for specific hardware to work within a specific operating system kernel and to support a range of APIs used by applications to access the graphics hardware. They may also control output to the display if the display driver is part of the graphics hardware. Most free and open-source graphics device drivers are developed by the Mesa project. The driver is made up of a compiler, a rendering API, and software which manages access to the graphics hardware.
Maemo was a software platform developed by Nokia for smartphones and Internet tablets. The platform comprises both the Maemo operating system and SDK.
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged in a Linux distribution.
Openmoko Linux is an operating system for smartphones developed by the Openmoko project. It is based on the Ångström distribution, comprising various pieces of free software.
SHR is a community-driven Linux distribution for smartphones which is based on OpenEmbedded and the FSO framework. Several different graphical toolkits are made available, such as GTK+ and Qt.
An app store is a type of digital distribution platform for computer software called Applications, often in a mobile context. Apps provide a specific set of functions which, by definition, do not include the running of the computer itself. Complex software designed for use on a personal computer, for example, may have a related app designed for use on a mobile device. Today apps are normally designed to run on a specific operating system—such as the contemporary iOS, macOS, Windows or Android—but in the past mobile carriers had their own portals for apps and related media content.
Replicant is a free operating system (OS) based on the Android mobile platform that aims to replace all proprietary Android components with free-software counterparts. It is available for several smartphones and tablet computers. It is written in the same programming languages as Android, /c/while the modifications are mostly in the C language, as the changes are mostly to the lower-level parts of the OS, such as the Linux kernel and drivers that use it.
Werner Almesberger is an Austrian free software computer programmer and an open-source hardware designer/maker. He is mainly known as a hacker of the Linux kernel.
