Astro::DSS Module is an object orientated Perl module that provides an interface to both the first and second Digital Sky Surveys at the ESO-ECF online archive. While the first sky survey is 100% complete, the second survey covers 98% of the sky in Red, 45% of the sky in Blue, and 27% of the sky in Infra-red.
The Astro::ADS module is an OO Perl interface to the Astrophysics Data System (ADS) abstract service. The ADS is a NASA-funded project whose main resource is an Abstract Service, which includes four sets of abstracts: astronomy and astrophysics, instrumentation, physics and geophysics, and Los Alamos preprint server.
Multi-body Gravity Simulator (MGS) allows you to perform a simulation based on a fixed time slice. Its unique features are the ability to perform realtime simulations, a three dimensional visualization of the simulation, and the ability to design simulations in XML and with a GUI. The accuracy of realtime simulations will depend on your machine speed. Fixed time step simulations are also supported.
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.
