Computer Software
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AdvFS
AdvFS, also known as Tru64 UNIX Advanced File System, is a file system developed in the late 1980s to mid-1990s by Digital Equipment Corporation for their OSF/1 version of the Unix operating system (later Digital UNIX/Tru64 UNIX). In June 2008, it was released as free software under the GPL-2.0-only license. AdvFS has been used in high-availability systems where fast recovery from downtime is essential. Functionality AdvFS uses a relatively advanced concept of a storage pool (called a file domain) and of logical file systems (called file sets). A file domain is composed of any number of block devices, which could be partitions, LVM or LSM devices. A file set is a logical file system created in a single file domain. Administrators can add or remove volumes from an active file domain, providing that there is enough space on the remaining file domain, in case of removal. This was one of the trickier original features to implement because all data or metadata residing on the dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delphi (software)
Delphi is a general-purpose programming language and a software product that uses the Delphi dialect of the Object Pascal programming language and provides an integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies.

Patreon
Patreon (, ) is a membership platform that provides business tools for content creators to run a subscription service. It helps creators and artists earn a monthly income by providing rewards and perks to their subscribers. Patreon charges a commission of 9 to 12 percent of creators' monthly income, in addition to payment processing fees. Patreon is used by YouTube videographers, webcomic artists, writers, podcasters, musicians, adult content creators, and other categories of creators who post regularly online. It allows artists to receive funding directly from their fans, or patrons, on a recurring basis or per work of art. The company is based in San Francisco. History Patreon was co-founded in May 2013 by developer Sam Yam and musician Jack Conte, who was looking for a way to make a living from his YouTube videos. They developed a platform that allowed 'patrons' to pay a set amount of money every time an artist created a work of art. The company raised $2.1 million i ...

BSD Licenses
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses. BSD is both a license and a class of license (generally referred to as BSD-like). The modified BSD license (in wide use today) is very similar to the license originally used for the BSD version of Unix. The BSD license is a simple license that merely requires that all code retain the BSD license notice if redistributed in source code format, or reproduce the notice if redistributed in binary format. The BSD license (unlike some other licenses e.g. GPL) does not require that source code be distributed at all. Terms In additi ...

Google Wave
Google Wave, later known as Apache Wave, was a software framework for real-time collaborative editing online. Originally developed by Google and announced on May 28, 2009, it was renamed to ''Apache Wave'' when the project was adopted by the Apache Software Foundation as an incubator project in 2010. Wave is a web-based computing platform and communications protocol designed to merge key features of communications media, such as email, instant messaging, wikis, and social networking. Communications using the system can be synchronous or asynchronous. Software extensions provide contextual spelling and grammar checking, automated language translation and other features. Initially released only to developers, a preview release of Google Wave was extended to 100,000 users in September 2009, each allowed to invite additional users. Google accepted most requests submitted starting November 29, 2009, soon after the September extended release of the technical preview. On May 19, 20 ...

Apache Software Foundation
The Apache Software Foundation (ASF) is an American nonprofit corporation (classified as a 501(c)(3) organization in the United States) to support a number of open source software projects. The ASF was formed from a group of developers of the Apache HTTP Server, and incorporated on March 25, 1999. As of 2021, it includes approximately 1000 members. The Apache Software Foundation is a decentralized open source community of developers. The software they produce is distributed under the terms of the Apache License and is a non-copyleft form of free and open-source software (FOSS). The Apache projects are characterized by a collaborative, consensus-based development process and an open and pragmatic software license, which is to say that it allows developers who receive the software freely, to re-distribute it under nonfree terms. Each project is managed by a self-selected team of technical experts who are active contributors to the project. The ASF is a meritocracy, implying ...

Relational Database Management System
A relational database is a (most commonly digital) database based on the relational model of data, as proposed by E. F. Codd in 1970. A system used to maintain relational databases is a relational database management system (RDBMS). Many relational database systems are equipped with the option of using the SQL (Structured Query Language) for querying and maintaining the database. History The term "relational database" was first defined by E. F. Codd at IBM in 1970. Codd introduced the term in his research paper "A Relational Model of Data for Large Shared Data Banks". In this paper and later papers, he defined what he meant by "relational". One well-known definition of what constitutes a relational database system is composed of Codd's 12 rules. However, no commercial implementations of the relational model conform to all of Codd's rules, so the term has gradually come to describe a broader class of database systems, which at a minimum: # Present the data to the user as re ...
