Calc is arbitrary precision arithmetic system that uses a C-like language. It's useful as a calculator, an algorithm prototype, and as a mathematical research tool. More importantly, calc provides a machine-independent means of computation. Calc comes with a rich set of builtin mathematical and programmatic functions.
syslog-ng is a syslogd replacement for a wide variety of UNIX systems that supports IPv6 and is capable of transferring log messages reliably using TCP and SSL and filtering the content of messages using regular expressions. Both RFC3164 and RFC5424 style messages are handled, but more esoteric formats like BSD process accounting logs are supported too. Apart from regular text files, it supports storing messages into SQL and MongoDB databases, and forward messages to local processes via pipes or UNIX domain sockets. This makes syslog-ng ideal as an integration platform. syslog-ng supports extracting structured information from the traditionally text based syslog via csv-parser(), db-parser(), and patterndb. Tag based classification, rewriting messages, and outputting messages in JSON is also possible. This makes syslog-ng ideal for preprocessing events for further analysis, be that home-grown scripts or SIEM systems. syslog-ng scales well on today's multi processor and multi-core systems: reaching 1,000,000 messages per second is a reality for the simplest use cases.
white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
JExpress is a Java installer builder and auto-updater. It gives you your choice of a standalone installer, including both native and cross platform installers and updaters for Windows, Mac OS X, Linux, and Solaris, or a Java Web Start one-click install. You create your installer quickly with your choice of a simple wizard or a powerful advanced interface, both included. You can bundle the exact JVM you want with your installer. The auto-updater gives you a continuous revenue stream after the sale. Your software is always up-to-date, so your customers have fewer problems. You also get all the features you expect in a top end installer. Your Java application becomes a native program just like any other. On Windows it's an EXE, on Mac OS X an app bundle, etc. If you need something really special, you can customize your installer by adding simple Java classes. You can even get a source license at a reasonable price.
ICBM3D (Inter-Continental Ballistic Missiles, 3D) is a 3D game of defense. Like the original "Missile Command" and its clones, this game places you in control of Anti-ICBM weapons which you use to destroy an onslaught of missiles (and other nasties) which are dropping onto your nation. The game ends when your cities have all been destroyed. You only gain replacement cities by acheiving certain score thresholds during each attack. The differences between Missile Command and ICBM3D is that ICBM3D, as the name suggests, provides a 3D perspective. You take advantage of X-Window's 3-button mouse to control your firing sight in 3-dimensions and change your viewpoint.
