DeviceKit
DeviceKit is a modular hardware abstraction layer designed for use in Linux systems that is designed to simplify device management and replace the current monolithic Linux HAL. DeviceKit includes the ability to enumerate system devices and send notifications when hardware is added or removed from the computer system. In May 2008, HAL developer David Zeuthen announced his intention to deprecate HAL, mainly because of its complexity and redundancy with other libraries in the Linux environment. The only missing part in those libraries would be a centralized service to enumerate existing devices, signal adding/removal of devices and merging and classifying available hardware information in one point. DeviceKit is the new library providing those services, while the hardware is supposed to be accessed through other libraries instead of HAL or DeviceKit. The first distribution to include DeviceKit was Fedora 11. Ubuntu 9.10 replaced some of the old HAL features with DeviceKit and func ...

DeviceKit-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 sm ...

Udev
udev (userspace ) is a device manager for the Linux kernel. As the successor of devfsd and hotplug, udev primarily manages device nodes in the directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices. Rationale It is an operating system's kernel that is responsible for providing an abstract interface of the hardware to the rest of the software. Being a monolithic kernel, the Linux kernel does exactly that: device drivers are part of the Linux kernel, and make up more than half of its source code. Hardware can be accessed through system calls or over their device nodes. To be able to deal with peripheral devices that are hotplug-capable in a user-friendly way, a part of handling all of these hotplug-capable hardware devices was handed over from the kernel to a daemon running in user-space. Running in user space serves security and stab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HAL (software)
HAL (Hardware Abstraction Layer or rather Hardware Annotation Library) is a software subsystem for UNIX-like operating systems providing hardware abstraction. HAL is now deprecated on most Linux distributions and on FreeBSD. Functionality is being merged into udev on Linux as of 2008–2010 and devd on FreeBSD. Previously, HAL was built on top of udev. Some other OS-es which don't have an alternative like udev or devd still use HAL. The purpose of the hardware abstraction layer was to allow desktop applications to discover and use the hardware of the host system through a simple, portable and abstract API, regardless of the type of the underlying hardware. HAL for Linux OS was originally envisioned by Havoc Pennington. It became a freedesktop.org project, and was a key part of the software stack of the GNOME and KDE desktop environments. It is free software, dual-licensed under both the GNU General Public License and the Academic Free License. HAL is unrelated to the conc ...

Hardware Abstraction Layer
Hardware abstractions are sets of routines in software that provide programs with access to hardware resources through programming interfaces. The programming interface allows all devices in a particular class ''C'' of hardware devices to be accessed through identical interfaces even though ''C'' may contain different subclasses of devices that each provide a different hardware interface. Hardware abstractions often allow programmers to write device-independent, high performance applications by providing standard operating system (OS) calls to hardware. The process of abstracting pieces of hardware is often done from the perspective of a CPU. Each type of CPU has a specific instruction set architecture or ISA. The ISA represents the primitive operations of the machine that are available for use by assembly programmers and compiler writers. One of the main functions of a compiler is to allow a programmer to write an algorithm in a high-level language without having to care a ...

Haiku Device Kit
is a type of short form poetry originally from Japan. Traditional Japanese haiku consist of three phrases that contain a ''kireji'', or "cutting word", 17 '' on'' (phonetic units similar to syllables) in a 5, 7, 5 pattern, and a ''kigo'', or seasonal reference. Similar poems that do not adhere to these rules are generally classified as ''senryū''. Haiku originated as an opening part of a larger Japanese poem called renga. These haiku written as an opening stanza were known as ''hokku'' and over time they began to be written as stand-alone poems. Haiku was given its current name by the Japanese writer Masaoka Shiki at the end of the 19th century. Originally from Japan, haiku today are written by authors worldwide. Haiku in English and haiku in other languages have different styles and traditions while still incorporating aspects of the traditional haiku form. Non-Japanese haiku vary widely on how closely they follow traditional elements. Additionally, a minority movement with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User Interfaces
In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls and process controls. The design considerations applicable when creating user interfaces are related to, or involve such disciplines as, ergonomics and psychology. Generally, the goal of user interface design is to produce a user interface that makes it easy, efficient, and enjoyable (user-friendly) to operate a machine in the way which produces the desired result (i.e. maximum usability). This generally means that the operator needs to provide minimal input t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Human–computer Interaction
Human–computer interaction (HCI) is research in the design and the use of computer technology, which focuses on the interfaces between people (users) and computers. HCI researchers observe the ways humans interact with computers and design technologies that allow humans to interact with computers in novel ways. A device that allows interaction between human being and a computer is known as a "Human-computer Interface (HCI)". As a field of research, human–computer interaction is situated at the intersection of computer science, behavioral sciences, design, media studies, and several other fields of study. The term was popularized by Stuart K. Card, Allen Newell, and Thomas P. Moran in their 1983 book, ''The Psychology of Human–Computer Interaction.'' The first known use was in 1975 by Carlisle. The term is intended to convey that, unlike other tools with specific and limited uses, computers have many uses which often involve an open-ended dialogue between the user and t ...

PolicyKit
Polkit (formerly PolicyKit) is a component for controlling system-wide privileges in Unix-like operating systems. It provides an organized way for non-privileged processes to communicate with privileged ones. Polkit allows a level of control of centralized system policy. It is developed and maintained by David Zeuthen from Red Hat and hosted by the freedesktop.org project. It is published as free software under the terms of version 2 of the GNU Lesser General Public License. Since version 0.105, released in April 2012, the name of the project was changed from ''PolicyKit'' to ''polkit'' to emphasize that the system component was rewritten and that the API had changed, breaking backward compatibility. Fedora became the first distribution to include PolicyKit, and it has since been used in other distributions, including Ubuntu since version 8.04 and openSUSE since version 10.3. Some distributions, like Fedora, have already switched to the rewritten polkit. It is also possible ... [...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 around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux
Linux ( or ) 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 as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...
