JABM is a Java API for developing agent-based simulation models using a discrete-event simulation framework. It has a simple architecture in which agents are represented using plain-old Java objects (POJOs). Simulations are configured via dependency injection using the industry-standard Spring framework, thus allowing attributes of any object in the simulation to be specified as random variables to be drawn from a specified distribution without having to write any Java code. Attributes of any object can be specified as independent variables or treatments with a given range of values, and experiments with different treatments can be easily parallelized using, for example, SGE.
papercut is command line based rock, paper, scissors game for Unix based operating systems like GNU/Linux, BSD, etc. A user can play the game by entering their choice of rock (R or r), paper (P or p), or scissors (S or s). papercut also stores user statistics, i.e. number of wins, losses, and draws.
Meep is a free finite-difference time-domain (FDTD) simulation software package to model electromagnetic systems. It supports distributed-memory parallel simulations, nonlinear, anisotropic, and dispersive media, PML absorbing boundaries, and 1D/2D/3D and cylindrical problems. It is completely scriptable from either C++ or a Scheme (GNU Guile) interface.
yacts, yet another continuous time simulator, uses J+ to interpret scripts, defining systems of ordinary differential equations, which it solves. J+ is a functional non-imperative simulation language with lazy evaluation, based on the J programming language, a dialect of APL. A program in J+ is a collection of (possibly functional) J assignment statements, just like a set of formulae on a sheet of paper. The interpreter, implemented as a software library, knows the interdependencies between these formulae and is able to compute any of the defined quantities with minimal effort, keeping track of the values which were already computed. The driver program (such as yacts) may ask the interpreter to compute certain quantities and set the values for others (propagating the changes to dependents).
Babelize is a collection of localizations for Linux games. It currently features French, German, Polish, and Spanish translations for "Heroes of Might and Magic III", as well as French, German, and Spanish translations for "Alpha Centauri - Alien Crossfire". The goal of the project is to provide localizations for as many native Linux games as possible.
