Structure101 is a tool to understand, measure, and control software structure. It allows you to see exactly how your high-level components depend on each other and why. You can use it to find out immediately when your architecture is accidentally changed by code-level changes at the coal-face. It can help you control structural complexity, since it can measure the complexity of methods, classes, and packages and warn you when given limits are exceeded. It can also discover the locations of productivity-killing package dependency cycles.
CoverageMeter is a complete code coverage tool chain. It analyzes the performance of a software validation and permits the optimization of the testing process of C/C++ applications. It finds untested code sections, redundant tests, and unused source code. It works by instrumenting the source code at compilation time and by analyzing the execution report that the instrumentation produces.
beaTunes is an iTunes companion app capable of automatically analyzing your music collection to help you build better playlists. It analyzes BPM (beats per minute), silence at the beginning or end of a song, and the color (based on frequency spectrum) of a given song. Some of the data is stored through iTunes, and some is stored by beaTunes itself. beaTunes can suggest albums that would complement your music collection, display music charts, and help you find and fix errors in your song meta data, like typos and wrong genres. It also allows you to blog about selected songs or playlists.
Perceptual Image Diff is a command line utility that tells you if two similar images are different from the point of view of a theoretical human observer. It's useful for running automated regression testing on images that are perceptually identical but have minor pixel noise from different random number generators or small changes to algorithms.
