The SeaMonkey project is a community effort to develop an all-in-one Internet application suite. It contains an Internet browser, email and newsgroup client with an included Web feed reader, HTML editor, IRC chat, and Web development tools, and is sure to appeal to advanced users, Web developers, and corporate users. It uses much of the Mozilla source code powering such successful siblings as Firefox, Thunderbird, Camino, Sunbird, and Miro.
The OpenDBX libraries provide a unified and consistent API for software developers to different database management systems. The C and C++ libraries aim to implement access to the native database interfaces efficiently via a thin abstraction layer. They consist of a basic set of functions that are part of all vendor database libraries and can be extended by additional function blocks. Currently, Firebird/Interbase, MS SQL Server, MySQL, ODBC, Oracle, PostgreSQL, SQLite 2 and 3, and Sybase ASE are supported.
ArahPaint4 is a textile-oriented paint program, mainly for jacquard. It is a simple paint program for raster palette images. It has good tools for drawing images in repetition, support for handling palette images (color reduction, substitution, protected, transparent colors), contour tools, layer support, unlimited undo/redo, support for drawing in aspect ratio (pixels need not be square), a two level grid, and a coordinates display. It is simple, stable, fast, and works well on large images (>8000x8000).
FreeCAD is a CAx RAD based on OpenCASCADE, Qt4, and Python. It features some key concepts like Macro recording, Workbenches, and the ability to run as a server. It's also platform-independent. It is is fully scriptable and designed to be easily extensible; only the core functionality is embedded into the core libraries, but all further functionality like support of triangle meshes, CAM, FEM, etc. is implemented in extension modules. Normally, such a module is divided into an 'App' part containing the data structures and algorithms and a 'GUI' containing the graphical representation of data structures, dialogs, workbenches, etc.
ArahPaint4 is a raster based paint program for drawing images in repeat, mainly for textiles. It includes a graphical image browser, works well on large images, allows limited image palettes, and supports drawing with non-square pixels. It is used in industry by over 300 textile mills, schools, and designers.
