TSPSG is intended to generate and solve "travelling salesman problem" (TSP) tasks. It uses the Branch and Bound method for solving. Its input is a number of cities and a matrix of city-to-city travel costs. The matrix can be populated with random values in a given range (which is useful for generating tasks). The result is an optimal route, its price, step-by-step matrices of solving, and a solving graph. The task can be saved in an internal binary format and opened later. The result can be printed or saved as PDF, HTML, or ODF. TSPSG may be useful for teachers to generate test tasks or just for regular users to solve TSPs. Also, it may be used as an example of using the Branch and Bound method to solve a particular task.
QSynergy is a comprehensive and easy-to-use graphical front end for Synergy. Synergy lets a user control more than one computer with a single mouse and keyboard (and has lots and lots of extra features on top of that). Since Synergy only has a GUI for MS Windows, QSynergy was written to step in and fill this gap for users on Mac and Unix platforms.
The cdcat is a graphical (Qt based) multi-platform catalog program that scans the directories/drives you want and memorizes the filesystem (including the tags of MP3s) and stores it in a small file. The database is stored in a gzipped XML format, so you can hack it, or use it if necessary. Cdcat can store the contents of some specified files up to a size limit if you want (for example: *.nfo).
