The DiskPulse GUI application provides the user with the ability to start/stop disk change monitoring operations, review detected file system changes and export reports. The bottom part of the DiskPulse GUI application includes the 'Categories' pane, which is capable of categorizing detected file system changes by the file type, size, extension, user name, etc. and allows one to filter changes by one or more change categories. The pie charts dialog is capable of showing numbers of changed files and the amount of changed disk space per extension, change type, file size and file type. In addition, the user is provided with the ability to copy the chart image to the clipboard allowing one to easily integrate DiskPulse charts into presentations and documents. The profile dialog's 'Monitor' tab allows one to specify one or more disks or directories that should be monitored. In the Victorian era – or for non-British readers, the mid-to-late nineteenth century – amateur astronomy tended to center on Solar System objects.All the specified directories will be monitored recursively including all subdirectories. The Moon and planets, as well as bright comets, were the key objects of interest. The brighter variable stars were monitored, but photography was in its infancy and digital imaging lay a century in the future. Today, at the start of the twenty-first century, amateurs are better equipped than any professionals of the mid-twentieth century, let alone the nineteenth. An amateur equipped with a 30-cm telescope and a CCD camera can easily image objects below magnitude 20 and, from very dark sites, 22 or 23. Such limits would have been within the realm of the 100- and 200-inch reflectors on Mount Wilson and Mount Palomar in the 1950s, but no other observatories. However, even those telescopes took hours to reach such limits, and then the photographic plates had to be developed, fixed, and examined by eye. In the modern era digital images can be obtained in minutes and analyzed ‘on the fly’ while more images are being downloaded.
