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.
The Lightweight Java Game Library is a native binding for OpenGL and OpenAL written with game developers in mind. It allows the full OpenGL and OpenAL APIs to be exposed without the penalties associated with competing methods, nor the limitations of APIs such as Java3D. Tutorials and demos are available, and Windows, Linux, and Mac OS X are supported.
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.
The FIX message viewer is a set of Ruby scripts that parse FIX (Financial Information eXchange protocol) messages to display them in a more human-readable format. The viewer can only parse FIX messages in a file or from STDIN. It also expects a full FIX message on each line. The FIX message can be prepended with a timestamp, but this will be ignored. The output is colored to make it easier to read, and the MsgType field is highlighted. The log viewer works on the command line only, and requires that Ruby is installed.
