libffi is a library that really only provides the lowest, machine dependent layer of a fully featured foreign function interface. A layer must exist above libffi that handles type conversions for values passed between the two languages. ffi stands for Foreign Function Interface. A foreign function interface is the popular name for the interface that allows code written in one language to call code written in another language.
OzVM (Virtual Machine Project) is a simple, lightweight, secure virtual machine. The current target application of OzVM is OzStream, which allows platform independent self-decoding of data. The vision of OzStream is to make any and all compressed media self-extracting. OzStream abstracts compressed media from client applications, providing new freedom for users, developers, and compression techniques.
Open Runtime Platform (ORP) is a Java Virtual Machine (JVM) that implements advanced JIT and GC interfaces. These interfaces allow the JIT, GC, and remaining runtime system to be developed in complete isolation and at independent rates. A major benefit is that JIT and GC researchers are relieved of the intractable task of developing a full system before they can innovate in their area of expertise.
Extended Tcl (TclX) is an extension to Tcl, the Tool Command Language invented by Dr. John Ousterhout. Tcl is a simple and powerful embeddable programming language. Extended Tcl is oriented toward system programming tasks and large application development. TclX provides additional interfaces to the operating system. It also adds many new programming constructs, text manipulation tools, and debugging tools.
CFITSIO is a library of C and Fortran subroutines for reading and writing data files in the FITS (Flexible Image Transport System) data format. It simplifies the task of writing software that deals with FITS files by providing an easy to use set of high-level routines that insulate the programmer from the internal complexities of the FITS file format.
PICI-NMS is an object oriented middleware which makes possible sending messages in a networked environment or on a single host between applications using the library provided. The supported message sending mechanism is "publish/subscribe" and this is backed up by a very easy-to-use and intuitive C++ API which hides the underlying socket interface to make the message sending as transparent to the client as possible.
