The "Sound of Sorting" is a demo program containing many integer sorting algorithms. The algorithms are visualized in real time and augmented with sound effects, which are based on the values being compared. Animation speed and sound sustain can be customized while the algorithm is running. The visualization also highlights the algorithm's internal workings, which makes the demo program very useful for teaching sorting algorithms in an undergraduate computer science course. The program also counts the number of comparisons done by an algorithm, which can then be compared to the analytically derived value. The demo is implemented using the cross-platform toolkits wxWidgets and SDL, and can be executed on Windows, Linux, and Mac.
Siren Renamer is a tool that renames, moves, and copies files using an expression. A lot of information associated with a file can be used, including name, extension, dates, and selection number. Other information is extracted from files according to their type: audio, video, image (standard and raw), EXIF, IPTC, Office document, PDF, ePub, HTML, and many others. Many different operations can be performed on character strings, complete directory trees can be processed, and images can be viewed. For example, to change a file name to uppercase with the mp3 extension, the expression can be '%ub.mp3'.
delaboratory is an image postprocessing application. It allows you to modify the color and contrast of a photo in a creative way, using curves, a channel mixer, an equalizer, blur, an unsharp mask, high pass, vignette, dodge/burn, shadows/highlights, and blending in different colorspaces (sRGB, ProPhoto, LAB, CMYK, LCH, HSV, HSL) with floating-point precision. Each operation is stored as an adjustment layer, and you can watch a realtime preview.
BDay is a simple program to help you track birthdays and anniversaries. It runs when you start or log in to your computer, displays any events that are coming up, and then exits when you click OK. It does not hang around in the system tray or as a background process taking up your computer’s resources. If there are no events to be displayed, then you won't even see BDay run.
