ClusterKnoppix
openMosix was a free cluster management system that provided single-system image (SSI) capabilities, e.g. automatic work distribution among nodes. It allowed program processes (not threads) to migrate to machines in the node's network that would be able to run that process faster (process migration). It was particularly useful for running parallel applications having low to moderate input/output (I/O). It was released as a Linux kernel patch, but was also available on specialized Live CDs. openMosix development has been halted by its developers, but the LinuxPMI project is continuing development of the former openMosix code. History openMosix was originally forked from MOSIX by Moshe Bar on February 10, 2002 when MOSIX became proprietary software. openMosix was considered stable on Linux kernel 2.4.x for the x86 architecture, but porting to Linux 2.6 kernel remained in the alpha stage. Support for the 64-bit AMD64 architecture only started with the 2.6 version. On July 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Knoppix
KNOPPIX ( ) is an operating system based on Debian designed to be run directly from a CD / DVD ( Live CD) or a USB flash drive (Live USB), one of the first live operating system distributions (just after Yggdrasil Linux). Knoppix was developed by, and named after, Linux consultant Klaus Knopper. When starting a program, it is loaded from the removable medium and decompressed into a RAM drive. The decompression is transparent and on-the-fly. Although KNOPPIX is primarily designed to be used as a Live CD, it can also be installed on a hard disk like a typical operating system. Computers that support booting from USB devices can load KNOPPIX from a live USB flash drive or memory card. There are two main editions: the traditional compact-disc (700 megabytes) edition and the DVD (4.7 gigabytes) "Maxi" edition. The CD edition had not been updated since June 2013 until recently. As of version 9.1, CD images are being released once again. Each main edition has two language-sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Cluster
A computer cluster is a set of computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware. Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability. Computer clusters emerged as a result of convergence of a number of computing trends including t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
End-of-life (product)
An end-of-life product (EOL product) is a product at the end of the product lifecycle which prevents users from receiving updates, indicating that the product is at the end of its useful life (from the vendor's point of view). At this stage, a vendor stops the marketing, selling, or provisioning of parts, services, or software updates for the product. The vendor may simply intend to limit or end support for the product. In the specific case of product sales, a vendor may employ the more specific term "end-of-sale" ("EOS"). All users can continue to access discontinued products, but cannot receive security updates and technical support. The time-frame after the last production date depends on the product and relates to the expected product lifetime from a customer's point of view. Different lifetime examples include toys from fast food chains (weeks or months), mobile phones (3 years) and cars (10 years). Product support Product support during EOL varies by product.

Debian Free Software Guidelines
The Debian Free Software Guidelines (DFSG) is a set of guidelines that the Debian Project uses to determine whether a software license is a free software license, which in turn is used to determine whether a piece of software can be included in Debian. The DFSG is part of the Debian Social Contract. The guidelines # Free redistribution. # Inclusion of source code. # Allowing for modifications and derived works. # Integrity of the author's source code (as a compromise). # No discrimination against persons or groups. # No discrimination against fields of endeavor, like commercial use. # The license needs to apply to all to whom the program is redistributed. # License must not be specific to a product. # License must not restrict other software. The GNU GPL, BSD, and Artistic licenses are examples of licenses considered free. History The DFSG was first published together with the first version of the Debian Social Contract in July 1997. The primary author was Bruce Perens, with inp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Core Utilities
The GNU Core Utilities or coreutils is a package of GNU software containing implementations for many of the basic tools, such as cat, ls, and rm, which are used on Unix-like operating systems. In September 2002, the ''GNU coreutils'' were created by merging the earlier packages ''textutils'', ''shellutils'', and ''fileutils'', along with some other miscellaneous utilities. In July 2007, the license of the GNU coreutils was updated from GPL-2.0-or-later to GPL-3.0-or-later. The GNU core utilities support long options as parameters to the commands, as well as the relaxed convention allowing options even after the regular arguments (unless the environment variable is set). Note that this environment variable enables a different functionality in BSD. See the List of GNU Core Utilities commands for a brief description of included commands. Alternative implementation packages are available in the FOSS ecosystem, with a slightly different scope and focus, or license. For ...

Dpkg
dpkg is the software at the base of the package management system in the free operating system Debian and its numerous derivatives. dpkg is used to install, remove, and provide information about .deb packages. dpkg (Debian Package) itself is a low-level tool. APT (Advanced Package Tool), a higher-level tool, is more commonly used than dpkg as it can fetch packages from remote locations and deal with complex package relations, such as dependency resolution. Frontends for APT, like aptitude (ncurses) and synaptic (GTK), are used for their friendlier interfaces. The Debian package "dpkg" provides the dpkg program, as well as several other programs necessary for run-time functioning of the packaging system, including dpkg-deb, dpkg-split, dpkg-query, dpkg-statoverride, dpkg-divert and dpkg-trigger. It also includes the programs such as update-alternatives and start-stop-daemon. The install-info program used to be included as well, but was later removed as it is now developed and ...

Advanced Packaging Tool
Advanced package tool, or APT, is a free-software user interface that works with core libraries to handle the installation and removal of software on Debian, and Debian-based Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code. Usage APT is a collection of tools distributed in a package named ''apt''. A significant part of APT is defined in a C++ library of functions; APT also includes command-line programs for dealing with packages, which use the library. Three such programs are apt, apt-get and apt-cache. They are commonly used in examples because they are simple and ubiquitous. The ''apt'' package is of "''important''" priority in all current Debian releases, and is therefore included in a default Debian installation. APT can be considered a front-end to dpkg, friendlier than the olde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DistroWatch
DistroWatch is a website which provides news, distribution pages hit rankings, and other general information about various Linux distributions as well as other free software/ open source Unix-like operating systems. It now contains information on several hundred distributions and a few hundred distributions labeled as active. History The website was launched on 31 May 2001 and is maintained by Ladislav Bodnar. Initially, Bodnar also wrote the Distrowatch Weekly (DWW). In November 2008, Bodnar decided to step down from the post of editor for DWW. Bodnar said he would still continue to maintain the site while the DWW would be written by Chris Smart. As of 2017, DistroWatch has donated a total of US$47,739 to various open source software projects since the launch of the Donations Program in March 2004. Features The site maintains extensive comparison charts detailing differences between the package sets and software revisions of different distributions. It also provides som ...

Open-source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts a ...

Linux Distribution
A Linux distribution (often abbreviated as distro) is an operating system made from a software collection that includes 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 (for example, OpenWrt) and personal computers (for example, Linux Mint) to powerful supercomputers (for example, Rocks Cluster Distribution). A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System, or, more recently, Wayland), a window manager, and a desktop environment. Most of the included software is free and open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Usually, Linux distributions optionally include some proprietar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slashdot
''Slashdot'' (sometimes abbreviated as ''/.'') is a social news website that originally advertised itself as "News for Nerds. Stuff that Matters". It features news stories concerning science, technology, and politics that are submitted and evaluated by site users and editors. Each story has a comments section attached to it where users can add online comments. The website was founded in 1997 by Hope College students Rob Malda, also known as "CmdrTaco", and classmate Jeff Bates, also known as "Hemos". In 2012, they sold it to DHI Group, Inc. (i.e., Dice Holdings International, which created the Dice.com website for tech job seekers). In January 2016, BIZX acquired both slashdot.org and SourceForge. In December 2019, BIZX rebranded to Slashdot Media. Summaries of stories and hyperlinks to news articles are submitted by Slashdot's own users, and each story becomes the topic of a threaded discussion among users. Discussion is moderated by a user-based moderation system. Randomly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
