HashCash is an anti-spam, anti-DoS system for email. The concept centers around the sender of the mail completing a computationally expensive task (in this case, generating hash collisions) that the recipient can verify very quickly. This allows the sender to "pay" for transport in CPU cycles, creating artificial scarcity. Programs are included to add payment to messages (for the sender) and to verify message payment (for the recipient).
ZFolder2Product takes the contents of a Zope folder and creates a custom Zope Product, which then re-creates the entire folder contents when installed. The advantage of using ZFolder2Product over a normal Zope exportation is that the folder contents are saved in external files usable within a version control system like CVS. After re-importing the files, you can edit them using the Zope Management Interface and export them back to the filesystem.
AZStats is a JSP file that parses and displays the contents of an Azureus stats file (typically Azureus_Stats.xml). The JSP is totally self-contained. No additional files/classes are needed. Just drop the JSP into a JSP/servlet engine and edit the JSP so that it points to your Azureus_Stats.xml file (either locally or via http://), and it will display the contents in a readable format.
Light-Weight Visual Components Library (LwVCL) is a powerful, small, fast, efficient, framework of visual components that provides a rich set of customizable, flexible user interface components. There are versions for J2SE/J2ME Personal Profile, J2ME MIDP, .NET, and SWT. This provides a unified GUI framework for different platforms that provides the same API, the same concepts, and the same look and feel.
DevelKit Framework is an GNUstep/Cocoa framework with tools for reading, understanding, and generating source code from other applications. Its goal is to allow applications to generate code from non-textual representation, such as diagrams or other kinds of descriptions. Example features: an ObjectiveC source reader and generator, a project builder class, source structure related classes (class, method, and instance variables), templates, a tool for automatically generating accessor (getter ad setter), dealloc and archiving methods (interface and implementation) for a given class, and more.
