USB-TCP Bridge bridges communications between a Palm handheld connected with a USB cradle and a TCP/IP socket. It can be used, for example, with the GDB debugger (which normally connects to the Palm OS Emulator on TCP/IP port 2000) to debug on a Palm handheld instead of debugging on the Palm OS emulator. It can also be used to connect the Unix-based pilot-link synchronization tools to a Palm handheld on Mac OS X. There are many more features, like support for packaged redistribution with predefined settings, etc.

retainCounter is an application that converts a simple [object release] into a NSLog(@"object retainCount: %i",[object retainCount]); [object release]; command. This is sometimes useful if developers wish to know the current count of an object before it is released, which makes it easier to detect memory leaks.
