Drone is a system for automatically running simulation programs in batch mode, either on an arbitrary number of Internet hosts or on a single computer. It allows sweeps over arbitrary sets of parameters, as well as multiple runs for each parameter set, with a separate random seed for each run. It also includes a number of features to help with simulation record keeping, archiving, statistical validation, and replication.
DLC (Dynamically Loadable Classes) is a compact utility that allows loading of shared libraries with C++ classes at runtime in an elegant and convenient way. It has been tested on a Linux platform with gcc 2.95.2, but should work on other ELF platforms as well. A C++ compiler with RTTI support is required.
DiaCanvas is a generalized version of the drawing canvas used by DIA. It extends some features used by DIA and adds new ones, while preserving as many of the original features as possible. This project is no longer actively maintained. It is suggested that you try DiaCanvas2 instead.
Ciao is a complete Prolog system subsuming ISO-Prolog with a novel modular design which allows both restricting and extending the language. Ciao extensions currently include feature terms (records), higher-order, functions, constraints, objects, persistent predicates, a good base for distributed execution (agents), and concurrency. Libraries also support WWW programming, sockets, and external interfaces (C, Java, TCL/Tk, relational databases, etc.). An Emacs-based environment, a stand-alone compiler, and a toplevel shell are also provided.
cgi-util is a fast, easy to use C library for creating CGI programs. Functions are available for initialization (parsing), grabbing fields (by string, integer, double or boolean value), embedding HTML files, and more. It accepts both POST and GET request methods and has extensive error handling.
