A Portable Forth. It is aimed to be interpreted, or compiled to various architectures and VMs.
C-Prime, or C' in abbreviation, is simply an attempt to add some fun and modern features to C without sacrificing speed or power. We intend to make "down and dirty programming" a "more enjoyable" experience.
The dyncall library encapsulates architecture-, OS- and compiler-specific function call semantics in a virtual "push the arguments manually" (foreign function call) interface allowing programmers to call C functions in a completely dynamic manner.
kissme is a free (GPLed) Java Virtual Machine. It is being developed on GNU/Linux and can run console java applications. kissme is to be used with the GNU Classpath java class library. kissme also provides support for orthogonally persistent java.
