DNF (software)
DNF (abbreviation for Dandified YUM) is a package manager for Red Hat-based Linux distributions and derivatives. DNF was introduced in Fedora 18 in 2013 as a replacement for yum; it has been the default package manager since Fedora 22 in 2015 and Red Hat Enterprise Linux 8 and is also an alternative package manager for Mageia. DNF performs package management tasks on top of RPM, and supporting libraries. History Perceived deficiencies of yum (which DNF is intended to address) include poor performance, high memory usage, and the slowness of its iterative dependency resolution. DNF uses libsolv, an external dependency resolver. DNF was originally written in Python, but , efforts were under way to port it to C and move most functionality from Python code into the new libdnf library. In 2018, the DNF team announced the decision to move libdnf from C to C++. libdnf is already used by PackageKit, a Linux distribution-agnostic package system abstraction library, even though t ...

Graphical User Interface
A graphical user interface, or GUI, is a form of user interface that allows user (computing), users to human–computer interaction, interact with electronic devices through Graphics, graphical icon (computing), icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based user interface, text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation interface, direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and Distributed control system, industrial controls. The term ''GUI'' tends not to be applied to other lower-displa ... [...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 abstraction layer 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 PackageKit is still maintained, no major features have been develope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose 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 Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. 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 most widely used programming langu ...

Python (programming Language)
Python is a high-level programming language, high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is type system#DYNAMIC, dynamically type-checked and garbage collection (computer science), garbage-collected. It supports multiple programming paradigms, including structured programming, structured (particularly procedural programming, procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC (programming language), ABC programming language, and he first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000. Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions. Python 2.7.18, released in 2020, was the last release of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dependency Resolution
In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge ''(u,v)'' from vertex ''u'' to vertex ''v'', ''u'' comes before ''v'' in the ordering. For instance, the vertices of the graph may represent tasks to be performed, and the edges may represent constraints that one task must be performed before another; in this application, a topological ordering is just a valid sequence for the tasks. Precisely, a topological sort is a graph traversal in which each node ''v'' is visited only after all its dependencies are visited''.'' A topological ordering is possible if and only if the graph has no directed cycles, that is, if it is a directed acyclic graph (DAG). Any DAG has at least one topological ordering, and there are linear time algorithms for constructing it. Topological sorting has many applications, especially in ranking problems such as feedback arc set. Topological sorting is also ...

RPM Package Manager
RPM Package Manager (RPM) (originally Red Hat Package Manager, now a recursive acronym) is a free and open-source package management system. The name RPM refers to the file format and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base. Although it was created for use in Red Hat Linux, RPM is now used in many Linux distributions such as PCLinuxOS, Fedora Linux, AlmaLinux, CentOS, openSUSE, OpenMandriva and Oracle Linux. It has also been ported to some other operating systems, such as Novell NetWare (as of version 6.5 SP3), IBM's AIX (as of version 4), IBM i, and ArcaOS. An RPM package can contain an arbitrary set of files. Most RPM files are "binary RPMs" (or BRPMs) containing the compiled version of some software. There are also "source RPMs" (or SRPMs) containing the source code used to build a binary package. These have an appropriate tag in the file head ...

Mageia
Mageia is a Linux-based operating system, distributed as free and open-source software. It was forked from the Mandriva Linux distribution. The Greek term () means enchantment, fascination, glamour, wizardry. The first release of the software distribution, Mageia 1, took place in June 2011. History Mageia was created in 2010 as a fork of Mandriva Linux, by a group of former employees of Mandriva S.A. and several other members of the Mandriva community. On September 2, 2010, Edge IT, one of the subsidiaries of Mandriva, was placed under liquidation process by the Tribunal de commerce in Paris; effective September 17, all assets were liquidated and employees were let go. The next day, on September 18, 2010, some of these former employees, who were mostly responsible for the development and maintenance of the Mandriva Linux distribution, and several community members announced the creation of Mageia, with the support of many members of the community of developers, users and ...
