The Model Railroad System is a software package that can help you run your railroad. It allows you to operate your layout, from running trains to working your signals and switches. It has support for a network of Bruce Chubb CMR/I USIC, SUSIC, and/or SMINI nodes, and/or a network of Lenz's XPressNet DCC nodes. Azatrax USB-connected Model Railroad Detectors are supported. Software to create switch lists for freight car forwarding and create timetables for your railroad are included. There is software to help with photographing your trains, and to compute the correct value for those pesky dropping resistors for LEDs and/or incandescent lamps.
GPLIGC is a program for analyzing IGC flight data from GNSS flight data recorders used by glider pilots. It uses Perl/Tk and gnuplot. The openGLIGCexplorer (written in C++) allows one to view the data in 3D with OpenGL, and can also be used as a digital elevation model terrain viewer. It can also be used for off-screen rendering of 2D and 3D images of flight tracks or terrain/map data.
AutoGen is a tool designed for generating program files that contain repetitive text with varied substitutions. Its goal is to simplify the maintenance of programs that contain large amounts of repetitious text. This is especially valuable if there are several blocks of such text that must be kept synchronized. Output is specified with a Scheme-enhanced output template. Input, if required by your template, may come from AutoGen definitions, CGI data, or XML files.
XmlBlaster is XML based MOM (Message oriented Middleware) with a lot of features. It is a publish/subscribe and point-to-point MOM server which exchanges XML-encoded messages. Communication with the server is based on CORBA (using JacORB), RMI, XML-RPC, native socket, or a persistent HTTP plugin. Subscribers can use XPath expressions to filter the messages they wish to receive and add their own MIME-based filter plugins. C/C++, Java, Perl, Python, VisualBasic.net, C#, and PHP client demos are included in the xmlBlaster test suite, and Tcl and Python demo clients are scheduled. XmlBlaster also provides a browser callback framework, allowing browsers (Netscape, Mozilla, MSIE) to receive instant callbacks over a persistent http connection. A security plugin framework allows authentication/authorization in many ways. Currently there are LDAP- and passwd-based plugins available.
