Software is a collection of instructions and data that tell a computer how to work. This is in contrast to physical hardware, from which the system is built and actually performs the work. In computer science and software engineering, computer software is all information processed by computer systems, including programs and data. Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own.
A MUD is a multiplayer real-time virtual world, usually text-based. MUDs combine elements of role-playing games, hack and slash, player versus player, interactive fiction, and online chat. Players can read or view descriptions of rooms, objects, other players, non-player characters, and actions performed in the virtual world. Players typically interact with each other and the world by typing commands that resemble a natural language.
In multiplayer online games, a MUSH is a text-based online social medium to which multiple users are connected at the same time. MUSHes are often used for online social intercourse and role-playing games, although the first forms of MUSH do not appear to be coded specifically to implement gaming activity. MUSH software was originally derived from MUDs; today's two major MUSH variants are descended from TinyMUD, which was fundamentally a social game. MUSH has forked over the years and there are now different varieties with different features, although most have strong similarities and one who is fluent in coding one variety can switch to coding for the other with only a little effort. The source code for most widely used MUSH servers is open source and available from its current maintainers.
A computer programmer, sometimes called a software developer, a programmer or more recently a coder, is a person who creates computer software. The term computer programmer can refer to a specialist in one area of computers or to a generalist who writes code for many kinds of software.
AberMUD was the first popular open source MUD. It was named after the town Aberystwyth, in which it was written. The first version was written in B by Alan Cox, Richard Acott, Jim Finnis, and Leon Thrane based at University of Wales, Aberystwyth for an old Honeywell mainframe and opened in 1987.
A talker is a chat system that people use to talk to each other over the Internet. Dating back to the 1980s, they were a predecessor of instant messaging.
BatMUD is a medieval fantasy MUD, established in 1990. BatMUD is Finland-based and operated and owned by a non-profit organization, Balanced Alternative Techniques ry, officially registered 1994 in Helsinki, Finland.
DikuMUD is a multiplayer text-based role-playing game, which is a type of multi-user domain (MUD). It was written in 1990 and 1991 by Sebastian Hammer, Tom Madsen, Katja Nyboe, Michael Seifert, and Hans Henrik Stærfeldt at DIKU —the department of computer science at the University of Copenhagen in Copenhagen, Denmark.
The MUD trees below depict hierarchies of derivation among MUD codebases. Solid lines between boxes indicate code relationships, while dotted lines indicate conceptual relationships. Dotted boxes indicate that the codebase is outside the family depicted.
LPMud, abbreviated LP, is a family of MUD server software. Its first instance, the original LPMud game driver, was developed in 1989 by Lars Pensjö. LPMud was innovative in its separation of the MUD infrastructure into a virtual machine and a development framework written in the LPC programming language.
Genesis LPMud, a multi-player computer game, is the original LPMud founded in April 1989 by Lars Pensjö, now running on CD gamedriver and mudlib, and previously hosted by Chalmers Computer Society, though hosting has since been moved to a dedicated, private server. Medieval fantasy is the general theme. Roleplaying is expected.
TinyFugue, or tf, is a MUD client, primarily written for Unix-like operating systems. It is one of the earliest MUD clients in existence. It is a successor to the earliest MUD client, TinyTalk, through a never-officially-released improved version called TinyWar. It was developed by Ken Keys until 2008. Like the name suggests, it is primarily geared toward TinyMUD variants, but can easily be used or adapted for most other MUD types.
A MOO is a text-based online virtual reality system to which multiple users (players) are connected at the same time.
Multi-User Dungeon, or MUD, is the first MUD and the oldest virtual world in existence.
Lost Souls is a MUD, a text-based online role-playing game set in a medieval fantasy world. It has an extensive history of technical innovation in its field and has received critical praise.
Michael Lawrie is a British computer security and social networking expert known for many things ranging from running MUDs to accidentally being the world's first Cybersquatter. He lives in Cambridge, England where he created the Cambridge Freecycle group, one of the largest in Europe.
DGD, Dworkin's Game Driver, is an LPMud server written by Felix A. "Dworkin" Croes. DGD pioneered important technical innovations in MUDs, particularly disk-based object storage, full world persistence, separation of concerns between driver and mudlib, runtime morphism, automatic garbage collection, lightweight objects and LPC-to-C compilation.
Wizard is commonly used in MUDs, particularly LPMuds, AberMUDs and MU*, as a term for the MUD's developers and administrators. The usage originates with Richard Bartle's original MUD1 and MUD2. It is frequently abbreviated "wiz", which is sometimes used as a verb; to wiz is to become a wizard. The plural of "wiz" is "wizzes".
Xyllomer is a MUD, a text-based online role-playing game, founded in 1991 as PaderMUD. It was the first publicly accessible MUD to use Dworkin's Game Driver. It has been hosted in Germany throughout its history.
A.V.A.T.A.R. MUD is a free, online, massively multiplayer, fantasy, text-based role-playing game, set in a real-time virtual environment. It combines elements of role-playing games, hack and slash style computer games, adventure games and social gaming.
