YAGF is a graphical frontend for the cuneiform and tesseract OCR tools. It lets you open already scanned image files or obtain new images via XSane (scanning results are automatically passed to YAGF). Once you have a scanned image you can prepare it for recognition, select particular image areas for recognition, set the recognition language and so on. Recognized text is displayed in an editor window where it can be spell-checked, corrected, saved to disk, or copied to clipboard. YAGF also provides some facilities for a multi-page recognition.
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.
Sentinella is a desktop application that monitors your system activity and, when a condition is met, takes the action that you've chosen. While monitoring your CPU, memory, hard drive, and network usage, Sentinella can be programmed to take specific actions when setpoints for utilization or time are met. It can power off, reboot, or hibernate your system, kill an active process, throw an alarm, or execute any command. Sentinella integrates perfectly with the main desktop enviroments (KDE, GNOME, XFCE, and others) and works under many Unix systems.
HexGlass is a Tetris-like puzzle game based on a hexagonal grid. Ten different types of blocks continuously fall from above and you must arrange them to make horizontal rows of hexagonal bricks. Completing any row causes those hexagonal blocks to disappear and those above move downwards. The blocks gradually fall faster and the game is over when the screen fills up and blocks can no longer fall from the top.
