Jython is a Java implementation of the Python programming language. It allows users to compile Python source code to Java byte codes, and run the resulting bytecodes on any Java Virtual Machine. It is a very seamless and smooth integration with Java: from Python you have complete access to all Java libraries, can build applets, can integrate with Java beans, and can subclass Java classes in Python and vice versa. Like Python, and unlike Java, Jython can also be used interactively: just type some Jython code at the prompt and see the results immediately....

Rygel is a collection of DLNA (UPnP AV) services (devices in UPnP speak), implemented through a plug-in mechanism. UPnP in simplest words is a set of protocols that defines how different devices on a home network can seamlessly (without or with minimum configuration) communicate with each other. UPnP AV defines how multimedia systems could be built on top of that. DLNA in simple words is a long list of rules that implementers must comply to if they want to achieve interoperability with other implementations in the market....

Parrot is a virtual machine designed to efficiently compile and execute bytecode for dynamic languages. Parrot currently hosts a variety of language implementations in various stages of completion, including Tcl, Javascript, Ruby, Lua, Scheme, PHP, Python, Perl 6, APL, and a .NET bytecode translator. Parrot is not about parrots, though we are rather fond of them for obvious reasons....
