KBoincSpy is a KDE monitor and control utility for the BOINC distributed client. It displays a lot of useful information about the computation of work units, such as the percent of work done, estimates of the completion time, and credits granted. For some projects, it also reports interesting data about the content and signifiance of each work unit being analyzed. Through KDE's IO mechanism, KBoincSpy is able to monitor remote BOINC clients, and its plugin-based architecture offers support for a virtually unlimited number of projects.

Lynkeos processes astronomical webcam images. By stacking the best images, the signal to noise ratio is increased, and details lost in the noise of individual images become visible in the resulting image. This software accepts, as input, QuickTime, AVI, and MPEG sequences, or still images, in any image format supported by its active plugins (TIFF, FITS) and Cocoa. It generates a 16-bit RGB TIFF or a monochrome FITS image as output, to be further processed with some all-purpose image processing application.
