Dworkin's Game Driver

Dworkin's Game Driver

DGD, Dworkin's Game Driver (at one time called Dworkin's Generic Driver), is an LPMud server written by Felix A. "Dworkin" Croes.[1][2] 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.[1][3][4]

History

DGD's first public release was on August 12, 1993.[3]

The first publicly available MUD to use DGD was PaderMUD (later Xyllomer), in December 1993.[5]

The original primary development MUD for DGD was The Pattern,[6] referencing The Chronicles of Amber (like Croes's pseudonym Dworkin, which refers to Dworkin Barimen). It was taken offline sometime before February 1997.[7]

During the 1994-1995 academic year, DGD was a core element in a master's thesis at the Katholieke Universiteit Leuven. As part of the thesis work, a deterministic mechanism for handling arrays and mappings passed between objects was devised.[8]

In December 1995, exclusive rights to commercial use of DGD were acquired by BeeHive Internet Technologies, Inc., which sold an exclusive license to ichat in January 1996. ichat used DGD to establish the first Yahoo! chatrooms. ichat then became Acuity Corporation, which sold a sublicense to Skotos in February 1999. Skotos used DGD to create a series of online games. Acuity Corporation was later acquired by Quintus Corporation. In March 2001, the exclusive license was terminated due to the bankruptcy of that company.[4][9]

In 2002, DGD was used for academic research into persistent distributed object systems.[10]

In August 2005, DGD's commercial use rights were assigned back to Dworkin B.V., Croes's company.[4]

On February 3, 2010, DGD 1.4 was released as open-source software.[11]

"DGD, created by Dworkin aka Felix Croes, is a complete rewrite of the LPmud game. It differs from the original in that it is mostly a disk-based game. This means that the objects on the Mud are mostly stored on disk rather than kept in memory during play of the game. This method creates a Mud that does not use much memory, is somewhat fast, but requires a large amount of disk space. This is also one of the few Muds that can be used commercially, given the permission of its creator."

"Another type of server, called DGD (Dworkin's Game Driver), on the surface looks to be similar to LPMUD and even incorporates the LPC language, but is not derived from the LPMUD server. DGD is a new server that is designed to be LPMUD-compatible but adds a new level of programming flexibility—in fact, MirrorMOO, running on a DGD server, emulates the MOO server."

DGD isolated essential LPC functionality, leaving all, if any, game functionality completely up to the mudlib. [...] September 16, 1993 ¶ DGD is released in multi-player form as DGD 1.0.a4.
