GNOME Core Applications
GNOME Core Applications is a software suite of approximately 30 application software that are packaged as part of the standard free and open-source GNOME desktop environment. GNOME Core Applications have the look and feel of the GNOME desktop, and often utilize the Adwaita design language. Some applications have been written from scratch and others are ports. The employment of the newest graphical widgets offered by the latest version of GTK in order to implement the GNOME Human Interface Guidelines (HIG) ergonomically is the only feature which all GNOME Core Applications have in common. Some of the GNOME Core Applications are essential, while several are not, e.g. GNOME Weather. Most are graphical front-ends, e.g. GNOME Software, to underlying Linux system daemons, like e.g. journald, PackageKit, NetworkManager or PulseAudio. Configuration * Settings – main interface to configure various aspects of GNOME. Diverse panels represent graphical front-ends to configure the Ne ...

The GNOME Project
GNOME Project is a community behind the GNOME desktop environment and the software platform upon which it is based. It consists of all the software developers, artists, writers, translators, other contributors, and active users of GNOME. It is no longer part of the GNU Project. GNOME Foundation In August 2000, the GNOME Foundation was set up to deal with administrative tasks and press interest, and to act as a contact point for companies interested in developing GNOME software. While not directly involved in technical decisions, the Foundation does coordinate releases and decide which projects will be part of GNOME. Membership is open to anyone who has made a non-trivial contribution to the project. Members of the Foundation elect a board of directors every November, and candidates for the positions must be members themselves. Programs and events The GNOME Project holds several community programs and events, usually tailored to local users and developers. The main gathering of ...

GNOME Software
GNOME Software is a utility for installing applications and updates on Linux. It is part of the GNOME Core Applications, and was introduced in GNOME 3.10. It is the GNOME front-end to the PackageKit, in turn a front-end to several package management systems, which include systems based on both RPM and DEB. The program is used to add and manage software repositories as well as Ubuntu Personal Package Archives (PPA). Ubuntu replaced its previous Ubuntu Software Center program with GNOME Software starting with Ubuntu 16.04 LTS, and re-branded it as "Ubuntu Software". It also supports fwupd for servicing of system firmware. GNOME Software removed Snap support in July 2019, due to code quality issues, lack of integration (specifically, the user can't tell what snap is doing after they click "install" and that it generally ignores GNOME's settings), and the fact that it competes with the GNOME-supported Flatpak standard. Features The goals and use cases that GNOME Software targets ...

GNOME Calculator
GNOME Calculator, formerly known as gcalctool, is the software calculator integrated with the GNOME desktop environment. It is programmed in C and Vala and part of the GNOME Core Applications. Views * ''Basic'' – interface for basic arithmetic, resembling a desk calculator. * ''Advanced'' – an interface with scientific functions, and support for custom variables. * ''Financial'' – financial calculation and currency conversion. * ''Programming'' – a view with bit manipulation operators and radix conversion. * ''Keyboard'' – most of the space is taken up by the output, with no on-screen buttons. Supports currency and unit conversion. Notation The GNOME calculator uses the common infix notation for binary functions, such as the four basic arithmetic operations. Unlike many other calculators, it uses prefix notation, not postfix notation for unary functions. So to calculate e.g. the sine of one, the user must push the keys "sin", "1", "=" – not "1", "sin" as on many ...

GNOME Web
GNOME Web, called Epiphany until 2012 and still known by that code name, is a free and open-source web browser based on the GTK port of Apple's WebKit rendering engine, called WebKitGTK. It is developed by the GNOME project for Unix-like systems. It is the default and official web browser of GNOME, and part of the GNOME Core Applications. Despite being a component of GNOME, Web has no dependency on GNOME components, so it can be potentially installed on any system supporting GTK and WebKitGTK. GNOME Web is the default web browser on elementary OS and Bodhi Linux version 5. History Naming GNOME Web was originally named "Epiphany", but was rebranded in 2012 as part of GNOME 3.4. The name Epiphany is still used internally, as its code name, for development and in the source code. The package remains ''epiphany-browser'' in Debian (to avoid a name collision with a video game that is also called "Epiphany") and ''epiphany'' in Fedora. Development Galeon Marco Pesenti G ...

Disk Usage Analyzer
Disk Usage Analyzer is a graphical disk usage analyzer for GNOME. It was part of GNOME Core Applications, but was split off for GNOME 3.4. It was originally named Baobab after the ''Adansonia'' tree. The software gives the user a menu-driven, graphical representation of what is on a disk drive. The interface allows for selection of specific parts of filesystem being scanned so a single folder, the entire filesystem, and even remote folders and filesystems can be scanned. The graphical representation can be switched between a ring chart and a treemap chart so the presentation can be tailored to the specific content being scanned. In 2012, Disk Usage Analyzer was rewritten in Vala. Future At the GNOME Users And Developers European Conference GUADEC, the GNOME Users And Developers European Conference, is an annual developer conference, whose prime topic is the development of the GNOME desktop environment and its underlying base software, such as GTK, GStreamer, etc. The first ...

GNOME Disks
GNOME Disks is a graphical front-end for udisks. It can be used for partition management, S.M.A.R.T. monitoring, benchmarking, and software RAID (until v. 3.12). An introduction is included in the GNOME Documentation Project. Disks used to be known as GNOME Disk Utility or palimpsest Disk Utility. Udisks was named DeviceKit-disks in earlier releases. DeviceKit-disks is part of DeviceKit which was planned to replace certain aspects of HAL. HAL and DeviceKit have been deprecated. GNOME Disks has been included by default in several Linux distributions including Debian, Ubuntu, Linux Mint, Trisquel, Fedora, Red Hat Enterprise Linux and CentOS. See also * List of disk partitioning software * System monitor * Comparison of S.M.A.R.T. tools * GParted – another alternative * Disk utility A disk utility is a utility program that allows a user to perform various functions on a computer disk, such as disk partitioning and logical volume management, as well as multiple ...

GNOME Videos
GNOME Videos, formerly known as Totem, is a media player (audio and video) for the GNOME computer desktop environment. GNOME Videos uses the Clutter and GTK+ toolkits. It is officially included in GNOME starting from version 2.10 (released in March 2005), but ''de facto'' it was already included in most GNOME environments. Totem utilizes the GStreamer framework for playback, though until version 2.27.1, it could alternatively be configured to use the Xine libraries instead of GStreamer. GNOME Videos is free and open-source software subject to the requirements of the GPL-2.0-or-later license. Features Until recently there were two distinct versions of Totem, though the difference was not visible at the user interface level. One of them was based on GStreamer, which is a plugin-based multimedia framework. This version has superior extensibility and supports a larger variety of media formats. The other one was based on xine, which is a regular multimedia library. At the time the ...

GNOME Files
GNOME Files, formerly and internally known as Nautilus, is the official file manager for the GNOME desktop. Nautilus was originally developed by Eazel with many luminaries from the tech world including Andy Hertzfeld (Apple), chief architect for Nautilus. The nautilus name was a play on words, evoking the shell of a nautilus to represent an operating system shell. Nautilus replaced Midnight Commander in GNOME 1.4 (2001) and has been the default file manager from version 2.0 onwards. Nautilus was the flagship product of the now-defunct Eazel Inc and was released under the terms of the GNU Lesser General Public License. It is free and open-source software. History Nautilus was originally developed by Eazel and Andy Hertzfeld (founder of Eazel and a former Apple engineer) in 1999. Nautilus was first released in 2001 and development has continued ever since. The following is a brief timeline of its development history: * Version 1.0 was released on March 13, 2001, and incorporated ...

Evince
Evince (), also known as GNOME Document Viewer, is a free and open source document viewer supporting many document file formats including PDF, PostScript, DjVu, TIFF, XPS and DVI. It is designed for the GNOME desktop environment. The developers of Evince intended to replace the multiple GNOME document viewers with a single and simple application. The Evince motto sums up the project aim: "Simply a Document Viewer". GNOME releases have included Evince since GNOME 2.12 (September 2005). Evince's code is written mainly in C, with a small part (specifically, the interface with Poppler) written in C++. Many Linux distributions – including Ubuntu, Fedora Linux and Linux Mint – include Evince as the default document viewer. Evince is free and open-source software subject to the requirements of the GNU General Public License version 2 or later. The Evince FAQ highlights the meaning of the word "Evince" as "to show or express something clearly". History Evince began as a re ...

PulseAudio
PulseAudio is a network-capable sound server program distributed via the freedesktop.org project. It runs mainly on Linux, various BSD distributions such as FreeBSD and OpenBSD, macOS, as well as Illumos distributions and the Solaris operating system. PulseAudio is free and open-source software, and is licensed under the terms of the LGPL-2.1-or-later. It was created in 2004 under the name Polypaudio but was renamed in 2006 to PulseAudio. History Microsoft Windows was previously supported via MinGW (an implementation of the GNU toolchain, which includes various tools such as GCC and binutils). The Windows port has not been updated since 2011, however. Software architecture In broad terms ALSA is a kernel subsystem that provides the sound hardware driver, and PulseAudio is the interface engine between applications and ALSA. However, its use is not mandatory and audio can still be played and mixed together without PulseAudio. PulseAudio acts as a sound server, where a b ...

NetworkManager
NetworkManager is a daemon that sits on top of libudev and other Linux kernel interfaces (and a couple of other daemons) and provides a high-level interface for the configuration of the network interfaces. Rationale NetworkManager is a software utility that aims to simplify the use of computer networks. NetworkManager is available for Linux kernel-based and other Unix-like operating systems. How it works To connect computers with each other, various communications protocols have been developed, e.g. IEEE 802.3 (Ethernet), IEEE 802.11 ("wireless"), IEEE 802.15.1 (Bluetooth), PPPoE, PPPoA, and many many more. Each participating computer must have the suitable hardware, e.g. network card or wireless network card and this hardware must be configured accordingly to be able to establish a connection. In case of a monolithic kernel all the device drivers are part of it. The hardware is accessed (and also configured) through its device driver. In case of Linux, the kernel presents f ...
