Numerical Plotter by Abecedarical Systems

This source code enables you to plot the solutions to scientific and engineering problems. The Visual C++ programming environment was chosen for realization of numerical computation techniques. Visual C++ includes many advanced features that make it especially suitable for scientific and engineering computations. Visual C++ is also widely used; there is a wealth of information available on how to program with it.

20sim Viewer by Controllab Products BV

20-sim is an advanced modeling and simulation package for Windows. With 20-sim you can simulate the behavior of dynamic systems, such as electrical, mechanical and hydraulic systems or any combination of these. 20-sim models may use iconic diagrams, bond graphs, block diagrams as well as differential equations. Used in mechatronics, control engineering, robotics, mechanical engineering, hydraulics etc. From the same lab as Tutsim.

CVSChangeLogBuilder by Laurent Destailleur

cvschangelogbuilder is an Perl utility to generate ChangeLogs for a project hosted on a CVS server. The main goal is to provide a better output that the 'cvs log' command, to permit to choose the sorting criteria, to add the status of the change (added,removed,modified) and to allow "differential" changelogs, between 2 versions, even when they are not in the main branch.
