Jess is a fast, light rule engine and scripting environment written entirely in Java. You can build Java software that has the capacity to "reason" using knowledge you supply in the form of declarative rules. It is supplied as a programmer's library, making it ideal for embedding in larger applications. Jess includes development tools built on the Eclipse platform. It is free for academic use and can be licensed for commercial use.
Elca (Extended Line Calculator) is a real-time Perl calculator (i.e., it evaluates expressions immediately as you type them). It supports hexadecimal, octal, and binary numbers, complex numbers, variables, string, list and hash operations, etc. It can convert expressions from human style to valid Perl code before evaluating them, and has a mechanism for importing external modules, allowing almost arbitrary extensions.
Trace.java is a package used by Java programmers, testers, server administrators and others to understand what happened during the execution of a program. It doesn't generate tracing statements automatically; programmers have to add them. Trace messages go into an in-core ring buffer, a disk log, or both. The disk log can be fixed size with backups. What amount of detail gets logged can be controlled at runtime or launch time. The ring buffer and disk log can be controlled separately. Different subsystems of the code can be controlled independently.
CrazyBeans provides an API to read, analyze, modify, and create Rational Rose models. The aim of the project is to allow users to influence the process by which Rational Rose converts class diagrams into code and vice versa.It is designed to be convenient, flexible, and extensible. CrazyBeans also makes it possible to convert Rational Rose's proprietary file format into alternative formats.
JFCUnit enables you to write test cases for Java Swing-based applications. It provides support for obtaining handles on windows opened by your code, locating components within a component hierarchy, raising events on components (e.g., clicking a button), and handling testing of components in a thread-safe manner.
phpVideoPro is a program to manage your collection of DVDs, Video CDs, and video tapes. It stores all data in a database, and provides you with features for adding/changing entries, displaying lists, printing labels and lists, and more. An online help system is built-in to guide you when necessary, and an integrated user/session management protects your data against unauthorized access. Support for multiple languages is provided, and supported databases include MySQL and PostgreSQL; SQLite support is still experimental.
