Sepp is a version of the classic sliding puzzle game in which the properly ordered tiles form a picture. The picture is user-selectable, as is the tile-grid geometry. Additionally, Sepp implements an innovative kind of player aggravation: based on a user-configurable degree of evil, it decides, during each animation frame, whether it will disturb a tile while the game is in progress. Sepp is written for the DrScheme enviroment, which is available for all major platforms.
Inlab-Scheme is an independent implementation of the algorithmic language Scheme and conforms to the R4RS and the IEEE Standard 1178. In addition to the language core, Inlab-Scheme has support for image processing which allows the implementation of OCR and image recognition applications. Inlab-Scheme comes with two built in graphic file format converters which convert the PATIMG patent file format and the ST.33 patent file format to multipage TIFF without decompressing.
Dolda Connect is a modular P2P filesharing client built around the Direct Connect model. It supports most of the latest features of the DC protocol. It runs in client/server mode with a well defined protocol, allowing extensibility, flexibility, and multiple detachable user interfaces. It also has an optional multi-user mode.
guile spread is a guile module that conveniently wraps the Spread C libraries provided with the Spread 3.15.2 distribution. Spread is a local/wide area group communication toolkit that runs on most modern operating systems. It allows convenient mechanisms for reliable multicasting information between applications as well as providing many more complicated assurances.
Kahua is a continuation passing style (CPS) application framework and server. It is written using the Gauche implementation of Scheme. It has the advantage that you can use "continuations" easily, so you can solve the typical Web application's problem of process disconnection. It allows you to program declaratively by using S-expressions as a fundamental data type, you can use Kahua's Object Database to persist data, and you can modify the function being run, supporting incremental development.
