Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

Storm (software)
Storm is a Python programming library for object-relational mapping between one or more SQL databases and Python objects. It allows Python developers to formulate complex queries spanning multiple database tables to support dynamic storage and retrieval of object information. MySQL, PostgreSQL and SQLite database support is built into Storm, and the API allows for support for others. Storm also supports the Django and Zope web frameworks natively. Twisted support is planned for the .20 release. Development Storm was developed at Canonical Ltd. in Python for use in the Launchpad and Landscape applications and subsequently released in 2007 as free software. The project is free software and released under the GNU Lesser General Public License and contributors are required to assign copyrights to Canonical.

GNU GPL
The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses that guarantee end users the four freedoms to run, study, share, and modify the software. The license was the first copyleft for general use and was originally written by the founder of the Free Software Foundation (FSF), Richard Stallman, for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. These GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the Lesser General Public License and even further distinct from the more widely used permissive software licenses BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software domain. Prominent free software programs licensed under the GPL include the Linux kernel a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elementary OS
elementary OS is a Linux distribution based on Ubuntu LTS. It promotes itself as a "thoughtful, capable, and ethical" replacement to macOS and Windows and has a pay-what-you-want model. The operating system, the desktop environment (called Pantheon), and accompanying applications are developed and maintained by Elementary, Inc. Design philosophy The human interface guidelines of the elementary OS project focus on immediate usability with a gentle learning curve, rather than full-fledged customization. The three core rules the developers set for themselves were "concision", "accessible configuration" and "minimal documentation". Since its inception, elementary OS has received praise and criticism for its design. ''Wired'' claimed that it closely resembled macOS, visually and in user experience. The elementary developers maintain that any similarities are unintentional. Pantheon's main shell is deeply integrated with other elementary OS applications, like Plank (a dock), Web ...

Upstart (software)
Upstart was an event-based replacement for the traditional init daemon—the method by which several Unix-like computer operating systems perform tasks when the computer is started. It was written by Scott James Remnant, a former employee of Canonical Ltd. In 2014, Upstart was placed in maintenance mode, and other init daemons, such as systemd, were recommended in place of Upstart. Ubuntu moved away from Upstart with the release of version 15.04 (''Vivid Vervet'') in favor of migrating to systemd. As of January 2022, there have been no updates released for Upstart since September 2014. Rationale The traditional init process was originally only responsible for bringing the computer into a normal running state after power-on, or gracefully shutting down services prior to shutdown. As a result, the design is strictly synchronous, blocking future tasks until the current one has completed. Its tasks must also be defined in advance, as they are limited to this prep or cleanup func ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinta (software)
Pinta is an open-source, cross-platform bitmap image drawing and editing program inspired by Paint.NET, a similar image editing program which is limited to Microsoft Windows. Pinta has more features than Microsoft Paint. Compared with open-source image editor GIMP, Pinta is simpler and has fewer features. Features Pinta is a bitmap image editor with many features typical of image editing software including drawing tools, image filters and colour adjustment tools. The focus on usability is reflected in several of the main features of the program: * Unlimited undo history. * Multiple language support. * Flexible toolbar arrangement, including floating as windows or docking around the image edge. Unlike some simple image editing software, Pinta also features support for image layers. History and development Development of Pinta began in February 2010 and was driven by Jonathan Pobst, then working at Novell. In September 2011 Pobst announced that he was no longer interested ...

OpenStack
OpenStack is a free, open standard cloud computing platform. It is mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. Users manage it either through a web-based dashboard, through command-line tools, or through RESTful web services. OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. , it was managed by the OpenStack Foundation, a non-profit corporate entity established in September 2012 to promote OpenStack software and its community. By 2018, more than 500 companies had joined the project. In 2020 the foundation announced it would be renamed the Open Infrastructure Foundation in 2021. History In July 2010, Rackspace Hosting and NASA announced an open-source cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MariaDB
MariaDB is a community-developed, commercially supported fork of the MySQL relational database management system (RDBMS), intended to remain free and open-source software under the GNU General Public License. Development is led by some of the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle Corporation in 2009. MariaDB is intended to maintain high compatibility with MySQL, with library binary parity and exact matching with MySQL APIs and commands, allowing it in many cases to function as drop-in replacement for MySQL. However, new features are diverging. It includes new storage engines like Aria, ColumnStore, and MyRocks. Its lead developer/CTO is Michael "Monty" Widenius, one of the founders of MySQL AB and the founder of Monty Program AB. On 16 January 2008, MySQL AB announced that it had agreed to be acquired by Sun Microsystems for approximately $1 billion. The acquisition completed on 26 February 2008. Sun was then bought the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Mint
Linux Mint is a community-driven Linux distribution based on Ubuntu (which is in turn based on Debian), bundled with a variety of free and open-source applications. It can provide full out-of-the-box multimedia support for those who choose to include proprietary software such as multimedia codecs. The Linux Mint project was created by Clément Lefèbvre and is actively maintained by the Linux Mint Team and community. History Linux Mint began in 2006 with a beta release, 1.0, code-named 'Ada', based on Kubuntu. Linux Mint 2.0 'Barbara' was the first version to use Ubuntu as its codebase. It had few users until the release of Linux Mint 3.0, 'Cassandra'. Linux Mint 2.0 was based on Ubuntu 6.10, using Ubuntu's package repositories and using it as a codebase. It then followed its own codebase, building each release from the previous one, but continuing to use the package repositories of the latest Ubuntu release. This made the two systems' bases almost identical, guaranteeing f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JOSM
JOSM () ''(Java OpenStreetMap editor)'' is a free software desktop editing tool for OpenStreetMap geodata created in Java, originally developed by Immanuel Scholz and currently maintained by Dirk Stöcker. The editing tool contains advanced features that are not present in OSM's default online editor, iD. Features Some notable features of JOSM are importing GPX files (GPS tracks), working with aerial imagery (including WMS, TMS and WMTS protocols), support for multiple cartographic projections, layers, relations editing, data validation tools, data filtering, offline work, presets and rendering styles. JOSM provides more than 200 keyboard shortcuts for the core functions. Many additional features (like tools for drawing buildings, adding Wikipedia links or viewing data in 3D) are available through the plugins. There are more than 100 of them in the repository. History * The first changeset was created on 27 September 2005. * The first beta version (which required Java 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zope 3
Zope is a family of free and open-source web application servers written in Python, and their associated online community. Zope stands for "Z Object Publishing Environment", and was the first system using the now common object publishing methodology for the Web. Zope has been called a Python killer app, an application that helped put Python in the spotlight. Over the last few years, the Zope community has spawned several additional web frameworks with disparate aims and principles, but sharing philosophy, people, and source code. Zope 2 is still the most widespread of these frameworks, largely thanks to the Plone content management system, which runs on Zope 2. BlueBream (earlier called Zope 3) is less widespread but underlies several large sites, including Launchpad. Grok was started as a more programmer-friendly framework, "Zope 3 for cavemen", and in 2009 Pyramid gained popularity in the Zope community as a minimalistic framework based on Zope principles.
