jGRASP integrates the Control Structure Diagram (CSD) seamlessly and unobtrusively into source-code editing for Java, C, C++, Objective-C, Ada, and VHDL. The CSD is a control flow and data structure diagram that fits into the space normally taken by indentation in source code. Its intention is to improve the readability of source code. The CSD also enables source code folding in a meaningful way, based on code structures. jGRASP provides lots of editing features, an integrated Java debugger, UML dependency diagrams for Java, configurable colors and font size, and click-to-error for compile and runtime (Java stack dumps) errors.
XEMPIM is a complete rewrite of EMPIM (the Excessively Modular Personal Information Manager) for Mac OS X. It is written in Objective C/Cocoa to provide maximum compatibility with the OS X environment. The goal of (X)EMPIM is to create a core program which implements methods for loading, unloading, displaying, and communication between autonomous dynamically loadable modules. Each module provides a separate aspect of a standard PIM (Contact List, Calendar, etc).
