Hijra Islamic Calendar هجرة is an application for viewing the Islamic calendar (also known as Hijri calendar). It features a GUI with a tray applet. It includes both a high-level OOP library and a low-level library which can be used to implement other software that makes use of this type of calendar. It uses a special algorithm which gives much better precision than other known algorithms. It uses integer operations to avoid round off errors in floating point operations.
PyNOVAS allows you to calculate the position and movement of the sun, moon, planets, and stars with great precision using Python. It is based on the NOVAS software used by United States Naval Office (USNO) to produce the 'Astronomical Almanac' and 'MICA'. Ephemerides are supplied by the Jet Propulsion Laboratory (JPL). You can use this software for Celestial Navigation, and also as a basis for controlling astronomical equipment.
setirotate automatically spawns the SETI@Home commandline client, rotating it through work units in a work unit cache. You can configure the number of work units to store, the number of processes to run simultaneously, the number of simultaneous result-upload/workunit-download transfers, the time interval within which its allowed to perform said transfers, and the timeout interval for when a transfer fails. It will immediately start working on a work unit when the previous one finishes, while uploading the newly finished result (if the upload interval permits) in parallel. It strives to always keep something running.
wmJupiter is a Window Maker applet which features the planet Jupiter. It allows you to keep track of the Great Red Spot and the current distance in astronomical units (AE). The four Gallileo moons (Io, Europa, Ganymede, and Calisto) are also displayed when they are near the planet.
Henry is an educational astrometry utility for performing calculations based on a Hertzsprung-Russel (H-R) diagram, such as spectroscopic parallax for working out the distance to a given star. Unlike many other solutions that use in-built images for their H-R diagrams, Henry plots data directly from the European Space Agency's HIPPARCOS catalog, allowing increased accuracy while also giving students greater room to experiment by exploring the catalogue themselves.
