My cOLLection manager is a text-based database program for your collections. It is a fast and easy to use front end for gdbm or Berkeley DB with a curses interface. Some other databases are supported. The program was originally designed to organize a large music CD collection, but it has no restrictions on the entry of any other large range of items. Its main goal is flexibility.
OilCan is a native Universal Binary multithreaded query tool for PostgreSQL. It supports multiple query windows and multiple queries in one window, and includes a basic schema browser. Each query window gets its own connection. All queries run in their own thread, allowing other operations to continue while a long running query is running.
Green Dome GNUstepWeb for Mac OS X provides a WebObjects 4.5-like environment for Mac OS X (with some support for WO5 additions). It is composed of modified versions of the standard GNUstepBaseAdditions, GDL2, and GNUstepWeb frameworks, built to run on top of Apple's Cocoa frameworks. The GNUstep frameworks have been built with Xcode as true Mac OS X frameworks. Thus, they may be used as any other framework under Mac OS X. Note that this is a standalone package that does not require or interoperate with a separate GNUstep installation/environment. It is not intended to provide a complete GNUstep environment, such as would be expected of a full GNUstep installation.
