Open Arena
''OpenArena'' is a free and open-source video game. It is a first-person shooter, and a clone of ''Quake III Arena''. Development The ''OpenArena'' project was established on August 19, 2005, one day after the id Tech 3 source code released under GNU GPL-2.0-or-later license. OpenArena was officially released for Microsoft Windows, Linux, and macOS. Third parties have also ported the game to FreeBSD, OpenBSD, Android and iOS. The game was also unofficially ported to the Raspberry Pi. Gameplay ''OpenArenas gameplay mirrors that of ''Quake III Arena'' with some quality of life improvements, such as awarding a character points for pushing another character to their death. The game can be played online (against other human players) or offline (against computer-controlled characters known as bots). "Singleplayer" mode allows players to play a predefined series of deathmatches, unlocking a new "tier" of four maps after completing the previous one, or to create custom matche ...

Free Software Community
The free software movement is a social movement with the goal of obtaining and guaranteeing certain freedoms for software users, namely the freedoms to run, study, modify, and share copies of software. Software which meets these requirements, The Four Essential Freedoms of Free Software, is termed free software. Although drawing on traditions and philosophies among members of the 1970s hacker culture and academia, Richard Stallman formally founded the movement in 1983 by launching the GNU Project. Stallman later established the Free Software Foundation in 1985 to support the movement. Philosophy The philosophy of the Free Software Movement is based on promoting collaboration between programmers and computer users. This process necessitates the rejection of proprietary software and the promotion of free software. Stallman notes that this action would not hinder the progression of technology, as he states, "Wasteful duplication of system programming effort will be avoided. Th ...

Open-source Video Game
An open-source video game, or simply an open-source game, is a video game whose source code is open-source. They are often freely distributable and sometimes cross-platform compatible. Definition and differentiation Not all open-source games are free software; some open-source games contain proprietary non-free content. Open-source games that are free software and contain exclusively free content conform to DFSG, free culture, and open content and are sometimes called ''free games''. Many Linux distributions require for inclusion that the game content is freely redistributable, freeware or commercial restriction clauses are prohibited. Background In general, open-source games are developed by relatively small groups of people in their free time, with profit not being the main focus. Many open-source games are volunteer-run projects, and as such, developers of free games are often hobbyists and enthusiasts. The consequence of this is that open-source games often take long ...

OpenBSD
OpenBSD is a security-focused operating system, security-focused, free software, Unix-like operating system based on the Berkeley Software Distribution (BSD). Theo de Raadt created OpenBSD in 1995 by fork (software development), forking NetBSD 1.0. The OpenBSD project emphasizes software portability, portability, software standard, standardization, software bug, correctness, proactive computer security, security, and integrated cryptography. The OpenBSD project maintains portable versions of many subsystems as package manager, packages for other operating systems. Because of the project's preferred BSD license, which allows binary redistributions without the source code, many components are reused in proprietary and corporate-sponsored software projects. The firewall (computing), firewall code in Apple Inc., Apple's macOS is based on OpenBSD's PF (firewall), PF firewall code, Android (operating system), Android's Bionic (software), Bionic C standard library is based on OpenBSD c ...

FreeBSD
FreeBSD is a free-software Unix-like operating system descended from the Berkeley Software Distribution (BSD). The first version was released in 1993 developed from 386BSD, one of the first fully functional and free Unix clones on affordable home-class hardware, and has since continuously been the most commonly used BSD-derived operating system. FreeBSD maintains a complete system, delivering a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties such as GNU for system software. The FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The project includes a security team overseeing all software shipped in the base distribution. Third-party applications may be installed using the pkg package management system or from source via FreeBSD Ports. The project is supported and promoted by the FreeBSD Foundation ...

Fan-made
Fan labor, also called fan works, are the creative activities engaged in by fans, primarily those of various media properties or musical groups. These activities can include creation of written works (fiction, fan fiction and review literature), visual or computer-assisted art, films and videos, animations, games, music, or applied arts and costuming. Although fans invest significant time creating their products, and fan-created products are "often crafted with production values as high as any in the official culture," most fans provide their creative works as amateurs, for others to enjoy without requiring or requesting monetary compensation. Fans respect their gift economy culture and are often also fearful that charging other fans for products of their creativity will somehow fundamentally change the fan-fan relationship, as well as attract unwanted legal attention from copyright holders. The skills that fans hone through their fan works may be marketable, and some fans find ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software License
A software license is a legal instrument governing the use or redistribution of software. Since the 1970s, software copyright has been recognized in the United States. Despite the copyright being recognized, most companies prefer to sell licenses rather than copies of the software because it enables them to enforce stricter terms on redistribution. Very few purchasers read any part of the license, initially shrink-wrap contracts and now most commonly encountered as clickwrap or browsewrap. The enforceability of this kind of license is a matter of controversy and is limited in some jurisdictions. Service-level agreements are another type of software license where the vendor agrees to provide a level of service to the purchaser, often backed by financial penalties. Copyleft is a type of license that mandates derivative works to be licensed under the license's terms. Copyleft licenses exist for free and open-source software, but also for commercial applications like the Ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source Code
In computing, source code, or simply code or source, is a plain text computer program written in a programming language. A programmer writes the human readable source code to control the behavior of a computer. Since a computer, at base, only understands machine code, source code must be Translator (computing), translated before a computer can Execution (computing), execute it. The translation process can be implemented three ways. Source code can be converted into machine code by a compiler or an assembler (computing), assembler. The resulting executable is machine code ready for the computer. Alternatively, source code can be executed without conversion via an interpreter (computing), interpreter. An interpreter loads the source code into memory. It simultaneously translates and executes each statement (computer science), statement. A method that combines compilation and interpretation is to first produce bytecode. Bytecode is an intermediate representation of source code tha ...
