MUD

A MUD (/ˈmʌd/; originally Multi-User Dungeon, with later variants Multi-User Dimension and Multi-User Domain), 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.

Traditional MUDs implement a role-playing video game set in a fantasy world populated by fictional races and monsters, with players choosing classes in order to gain specific skills or powers. The objective of this sort of game is to slay monsters, explore a fantasy world, complete quests, go on adventures, create a story by roleplaying, and advance the created character. Many MUDs were fashioned around the dice-rolling rules of the Dungeons & Dragons series of games.

MUD2

MUD2 is the successor of MUD1, Richard Bartle's pioneering Multi-User Dungeon. Rather than a sequel, it is the result of over 20 years of continuous development, and is still largely based on the game's original code.

The game is nominally a roleplaying game, with a very strict set of rules, character classes and levels. Character progress up a ladder of 11 levels until they reach the traditional MUD goal of wiz (wizard or witch).

Characters move between locations, or game rooms, using compass directions, and basic commands such as GET LONGSWORD, GET DIAMOND, KILL DWARF WITH LONGSWORD. Points are scored by dropping treasure in the room known as the swamp, killing an NPC, or killing another player. The game also includes magical powers, which are gained through a mystical artifact known as The Touchstone. The small side effect of this is that touching the Touchstone may kill you, with the likelihood of death decreasing as you get higher in level. In order to make Wiz, one must also complete seven of eight tasks. Among wizzes' many powers is the ability to instantly kill any player in the land, using the much-vaunted Finger of Death, or FOD.

MUD1

Multi-User Dungeon, or MUD (referred to as MUD1, to distinguish it from its successor, MUD2, and the MUD genre in general) is the first MUD and the oldest virtual world in existence.

History

MUD was created in 1978 by Roy Trubshaw at Essex University on a DEC PDP-10 in the UK, using the MACRO-10 assembly language. He named the game Multi-User Dungeon, in tribute to the Dungeon variant of Zork, which Trubshaw had greatly enjoyed playing.Zork in turn was inspired by an older text-adventure game known as Colossal Cave Adventure or ADVENT.

In 1980, Roy Trubshaw created MUD version 3 in BCPL (the predecessor of C), to conserve memory and make the program easier to maintain.Richard Bartle, a fellow Essex student, contributed much work on the game database, introducing many of the locations and puzzles that survive to this day. Later that year Roy Trubshaw graduated from Essex University, handing over MUD to Richard Bartle, who continued developing the game. That same year, MUD1 became the first Internet multiplayer online role-playing game as Essex University connected its internal network to the ARPAnet.

CATS (software)

CATS (Computer Aided Transcription System) is an EDA software for mask data preparation (MDP) in integrated circuit design and manufacturing.

CATS receives tape out data output from the integrated circuit physical design step, most commonly in GDSII format, processes it, and converts into data that control the fabrication of photomasks used to manufacture the designed IC. CATS software tools generate photomask layers from input design layers and allow users to inspect the input and output data and verify its accuracy.

Originally it was developed by Transcription Enterprises, Ltd, acquired by Numerical Technologies, Inc. (2000). At the moment of acquisition, it was an industry standard for MDP operations, such as mask fracturing and mask inspection, with about 95% of market share. In its turn, Numeritech was acquired by Synopsys, Inc. (2003).

Traffic flow (computer networking)

In packet switching networks, traffic flow, packet flow or network flow is a sequence of packets from a source computer to a destination, which may be another host, a multicast group, or a broadcast domain. RFC 2722 defines traffic flow as "an artificial logical equivalent to a call or connection."RFC 3697 defines traffic flow as "a sequence of packets sent from a particular source to a particular unicast, anycast, or multicast destination that the source desires to label as a flow. A flow could consist of all packets in a specific transport connection or a media stream. However, a flow is not necessarily 1:1 mapped to a transport connection." Flow is also defined in RFC 3917 as "a set of IP packets passing an observation point in the network during a certain time interval."

Conceptual description

A flow can be uniquely identified by the following parameters within a certain time period:
