pygps is a GPS user interface. It shows a listing of satellites, their locations in the sky, a list of latitude, longitude, altitude, status, etc., and moving maps. It was designed to work on the Compaq (now HP) iPAQ PDA running Linux, with a 240x320 screen. However, it uses glade, so that it also works nicely on larger screens, or on a landscape orientation of 320x240. It works with any GPS receiver supported by gpsd (which see).
Xgravity is a program for the simulation of 3D gravitational motion of n-bodies. It reads a file with the current state of the bodies, and displays the motion. It features a nice isometric perspective, Red-Green stereographics, and a stereographic perspective which allows you to see the trace in "real" 3D. There is a GTK GUI interface in development, which gives you the ability to perform basic operations with the system, like modifing objects, rotating, eliminating drift, and launching a simulation.
PEXESO Evolutionary Methods Library is the library of Evolutionary Optimization Methods for Real Domains. It is based on the original Object Oriented Algorithmic model that consists of the multi- operators technology (currently it supports 13 operator types) and "open policy" on the selection strategy (currently 4 selection strategy types). Using this method you have a possibility to compose your own optimization method using some combination of operators and selection strategies, or you can use one of 3 precomposed algorithms. It is provided with several examples and comprehensive HTML documentation.
COSMIX is a general purpose N body integrator. It allows simulation of the behavior of gravitational systems according to different physical theories. The current release is only a test release - it only supports the newtonian approximation. The project aims at tackling relativity in coming releases.
The Linux Driver and API for Datel PC-462 project aims to produce a Linux driver and API for the Datel PC-462 Data Acquisition Card/Power Supply. From correspondence with Datel, there is no other Linux driver/API for this board. This software will allow developers and engineers to write test software that runs on Linux and incorporates the Datel hardware.
FaCiLe is a constraint programming library over integer finite domain written in OCaml. It offers all usual facilities to create and manipulate finite domain variables, arithmetic expressions and constraints (possibly non-linear), built-in global constraints, and search goals. It also allows you to build easily user-defined constraints and goals (including recursive ones), making pervasive use of OCaml higher-order functionals to provide a simple and flexible interface for the user.
