dopewars is a UNIX rewrite of the MS-DOS program of the same name, which in turn was inspired by John E. Dell's "Drug Wars" game. You have one month to buy and sell drugs on the streets of New York, the aim being first to pay off your debt to the loan shark and then to make a fortune. And if you have to shoot a few cops in the process, well... The game includes TCP networking allowing you to meet (and shoot) other human drug dealers. Computer drug dealers are currently in development.

ds3, short for dialup service 3, is a modem sharing server for Linux/UNIX. It allows no direct access to the modem/ISDN-adapter.

Features of ds3 include user authentification and scripts or programs may be lauched through events created by users or triggered by an interval.

e4Graph is a C++ library that allows programs to store graph-like data persistently and to access and manipulate that data efficiently. With e4Graph, you can arrange your data in the most natural form that reflects the relationships between its parts, rather than having to force it into a table-like format. The e4Graph library also allows you to concentrate on the relationships you want to represent, and not on how to store them in a database. You can modify data items, and add and remove connections and relationships between pieces of data on the fly. e4Graph allows you to represent an unlimited number of different connections between pieces of data, and your program can selectively manipulate the data according to the relationships it cares about, not having to know about other connections represented in the data set.
Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
