AppStream
AppStream is an agreement between major Linux vendors (i.e. Red Hat, Canonical, SUSE, Debian, Mandriva, etc.) to create an infrastructure for application installers on Linux and sharing of metadata. The initiative was started as early as 19-21 January, 2011. The project describes itself as: "''an initiative of cross-distro collaboration, which aims at creating an unified software metadata database, and also a centralized OCS (Open Collaboration Services) user-contributed content database, thus providing the best user experience.''" With the 0.6 release, the scope of the project was expanded to include more metadata for other software components, such as fonts, codecs, input-methods and generic libraries, which will allow applications to query information about software which is available in a distribution in a distribution-independent way. This enhances the quality of data displayed in software-centers, but also makes it possible for 3rd-party application installers like Listall ...

Listaller
Listaller is a free software, free computer software installation system (similar to a package management system) aimed at making it simple to create a package that can be installed on all Linux distributions as well as providing tools and API to make software management on Linux more user-friendly. History Listaller was started in December 2007 by freedesktop.org developer Matthias Klumpp as an experimental project to explore the possibility of writing a universal user interface to manage all kinds of Linux software, no matter how it was installed. Therefore, Listaller had backends to manage Autopackage, LOKIMojoand native distribution packages. The original project provided one user interface to manage all kinds of installed software. Interaction with the native distribution package management was done via an own abstraction layer, which was later replaced by PackageKit. Listaller also provided a cross-distribution software installation format which should have made it easier t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ubuntu Software Center
Ubuntu Software Center, or simply Software Center, is a discontinued high-level graphical front end for the APT/dpkg package management system. It is free software written in Python, PyGTK/ PyGObject based on GTK. The program was created for adding and managing repositories, as well as Ubuntu Personal Package Archives (PPA) and on Ubuntu, the Ubuntu Software Center also allowed users to purchase commercial applications. Development was ended in 2015 and in Ubuntu 16.04 LTS. It was replaced with GNOME Software. Development history In early 2009 Ubuntu developers noted that package management within Ubuntu could be improved and consolidated. Recent releases of Ubuntu, such as Ubuntu 9.04 (Jaunty Jackalope) included five applications for package management which consumed space and other resources, as well as provide confusion to users. Applications could be downloaded using the basic ''Add/Remove Applications'' or with the Synaptic Package Manager. The Software Updater ...

Apper
Apper (originally named KPackageKit) is a free and open source Linux front-end application for the PackageKit package management service by KDE. Apper also has one main difference compared to the old KPackageKit: Apper can list applications instead of listing only packages. This makes it much more user-friendly and allows the user to search for and install applications without the added complexity of dealing with packages and dependencies. Besides installation of new applications it also allows easy removal and updates. It can be compared to the Ubuntu Software Center as well as the AppStream project. Apper has been adopted by a few distributions such as Fedora, Debian and openSUSE openSUSE () is a free and open source RPM-based Linux distribution developed by the openSUSE project. The initial release of the community project was a beta version of SUSE Linux 10.0. Additionally the project creates a variety of tools, s ... 12.1. References External links * – Devel ...

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 targe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PackageKit
PackageKit is a free and open-source suite of software applications designed to provide a consistent and high-level front end for a number of different package management systems. PackageKit was created by Richard Hughes in 2007, and first introduced into an operating system as a default application in May 2008 with the release of Fedora 9. The suite is cross-platform, though it is primarily targeted at Linux distributions which follow the interoperability standards set out by the freedesktop.org group. It uses the software libraries provided by the D-Bus and Polkit projects to handle inter-process communication and privilege negotiation respectively. PackageKit seeks to introduce automatic updates without having to authenticate as root, fast-user-switching, warnings translated into the correct locale, common upstream GNOME and KDE tools and one software over multiple Linux distributions. Although bug fixes are still released, no major features have been developed since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snap (software)
Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel and the systemd init system. The packages, called ''snaps'', and the tool for using them, ''snapd'', work across a range of Linux distributions and allow upstream software developers to distribute their applications directly to users. Snaps are self-contained applications running in a sandbox with mediated access to the host system. Snap was originally released for cloud applications but was later ported to also work for Internet of Things devices and desktop applications. Functionality Snap Store The Snap Store allows developers to publish their snap-packaged applications. All apps uploaded to the Snap Store undergo automatic testing, including a malware scan. However, the scan does not catch all issues. In one case in May 2018, two applications by the same developer were found to contain a cryptocurrency miner which ran in the background during application e ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Zero Install
Zero Install is a means of distributing and packaging software for multiple operating systems (Unix-like including Linux and macOS, Windows). Software Rather than the normal method of downloading a software package, extracting it, and installing it before it can be used (with the accompanying use of destructive updates and privilege escalation), packages distributed using Zero Install only need be run. The first time software is accessed, it is downloaded from the Internet and cached; subsequently, software is accessed from the cache. Inside the cache, each application unpacks to its own directory, as in Application Directory systems. The system is intended to be used alongside a distribution's native package manager. Two advantages of Zero Install over more popular packaging systems are that it is cross-platform and no root password is needed to install software; packages can be installed in system locations writable by that user instead of requiring administrator access. ...

Package Manager
A package manager or package-management system is a collection of software tools that automates the process of installing, upgrading, configuring, and removing computer programs for a computer in a consistent manner. A package manager deals with ''packages'', distributions of software and data in archive files. Packages contain metadata, such as the software's name, description of its purpose, version number, vendor, checksum (preferably a cryptographic hash function), and a list of dependencies necessary for the software to run properly. Upon installation, metadata is stored in a local package database. Package managers typically maintain a database of software dependencies and version information to prevent software mismatches and missing prerequisites. They work closely with software repositories, binary repository managers, and app stores. Package managers are designed to eliminate the need for manual installs and updates. This can be particularly useful for large enterp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AppImage
AppImage is a format for distributing portable software on Linux without needing superuser permissions to install the application. It tries also to allow Linux distribution-agnostic binary software deployment for application developers, also called upstream packaging. Released first in 2004 under the name klik, it was continuously developed, then renamed in 2011 to PortableLinuxApps and later in 2013 to AppImage. Description Objectives AppImage aims to be an application deployment system for Linux with the following objectives: simplicity, binary compatibility, distro agnosticism, no installation, no root permission, being portable, and keeping the underlying operating system untouched. Properties AppImage does not install the application in the traditional Linux sense. Instead of putting the application's various files in the distro's appropriate places in the file system, the AppImage file is just the application's compressed image. When it runs, the file is mounted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatpak
Flatpak, formerly known as xdg-app, is a utility for software deployment and package management for Linux. It is advertised as offering a sandbox environment in which users can run application software in isolation from the rest of the system. Features Applications using Flatpak need permissions to have access to resources such as Bluetooth, sound (with PulseAudio), network, and files. These permissions are defined by the maintainer of the Flatpak and can be added or removed by users on their system. Another key feature of Flatpak is that it allows application developers to directly provide updates to users without going through distributions, and without having to package and test the application separately for each distribution. ''Flathub,'' a repository (or remote source in the Flatpak terminology) located at , has become the de facto standard for getting applications packaged with Flatpak. Packages are added to it by both the Flathub administrators and the developers of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library (computing)
In computer science, a library is a collection of non-volatile resources used by computer programs, often for software development. These may include configuration data, documentation, help data, message templates, pre-written code and subroutines, classes, values or type specifications. In IBM's OS/360 and its successors they are referred to as partitioned data sets. A library is also a collection of implementations of behavior, written in terms of a language, that has a well-defined interface by which the behavior is invoked. For instance, people who want to write a higher-level program can use a library to make system calls instead of implementing those system calls over and over again. In addition, the behavior is provided for reuse by multiple independent programs. A program invokes the library-provided behavior via a mechanism of the language. For example, in a simple imperative language such as C, the behavior in a library is invoked by using C's normal functi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
