WindowBuilder is a powerful and easy to use bi-directional
Java GUI designer that makes it very easy to create Java GUI
applications without spending a lot of time writing code to
display simple forms. With WindowBuilder you can create
complicated windows in minutes. Use the visual designer and
Java code will be generated for you. You can easily add controls
using drag-and-drop, add event handlers to your controls, change
various properties of controls using a property editor,
internationalize your app and much more.
JGraph is the most powerful, lightweight, feature-rich, and thoroughly
documented open-source graph component available for Java. It is accompanied
by JGraphpad, the first free diagram editor for Java that offers XML, Drag and
Drop and much more!
With the JGraph zoomable component, you can display objects and relations
(networks) in any Swing UI. JGraph can also be used on the server-side, for
example to read a GXL graph, apply a custom layout algorithm, and return the
result as a HTML image map.

MX4J is a project to build an Open Source implementation of the
Java(TM) Management Extensions (JMX) and of the JMX Remote API
(JSR 160) specifications, and to build tools relating to JMX.
JMX is an optional package for J2SE that provides a standard
way to manage applications. It can also be used to wrap legacy
systems and provide a standard interface to the outside world,
enabling the development of web services. JMX allows developers
to write more modular and loosely coupled system components and
reduce the complexity of large, interoperating systems.
CINT is a C/C++ interpreter aimed at processing C/C++ scripts.
CINT covers about 95% of ANSI C and 85% of C++. A CINT script can call
compiled classes/functions and compiled code can make callbacks to CINT
user defined functions. Utilities, like makecint and rootcint, automate
the process of embedding compiled C/C++ library code as shared objects
(as Dynamic Link Library, DLL, or shared library, .so). Source files
and shared objects can be dynamically loaded/unloaded without stopping
the CINT process. CINT offers a gdb like debugging environment for
interpreted programs.
mawk is an interpreter for the AWK Programming Language. The AWK language is
useful for manipulation of data files, text retrieval and processing, and for
prototyping and experimenting with algorithms. mawk is a new awk meaning it
implements the AWK language as defined in Aho, Kernighan and Weinberger, The
AWK Programming Language, Addison-Wesley Publishing, 1988 (hereafter referred
to as the AWK book.) mawk conforms to the Posix 1003.2 (draft 11.3) definition
of the AWK language which contains a few features not described in the AWK
book, and mawk provides a small number of extensions.
The Gambit programming system is a full implementation of the Scheme
language which conforms to the R4RS and IEEE Scheme standards. It
consists of two main programs: gsi-gambit, the Gambit Scheme
interpreter, and gsc-gambit, the Gambit Scheme compiler.
Gambit-C is a version of the Gambit programming system in which the
compiler generates portable C code, making the whole Gambit-C system
and the programs compiled with it easily portable to many computer
architectures for which a C compiler is available. With appropriate
declarations in the source code the executable programs generated by
the compiler run roughly as fast as equivalent C programs.
Rhino is an open-source implementation of JavaScript written entirely
in Java. It is typically embedded into Java applications to provide
scripting to end users.
Rhino is an implementation of the core language only and doesn't contain
objects or methods for manipulating HTML documents.
Rhino contains
* All the features of JavaScript 1.6
* Allows direct scripting of Java
* A JavaScript shell for executing JavaScript scripts
* A JavaScript compiler to transform JavaScript source files
into Java class files
* A JavaScript debugger for scripts executed with Rhino
Rubinius is an implementation of the Ruby programming language.
The Rubinius bytecode virtual machine is written in C++, incorporating
LLVM to compile bytecode to machine code at runtime. The bytecode compiler
and vast majority of the core classes are written in pure Ruby.
To interact with the rest of the system, the VM provides primitives which can
be attached to methods and invoked. Additionally, FFI provides a direct call
path to most C functions.
Rubinius uses a precise, compacting, generational garbage collector. It
includes a compatible C-API for C extensions written for the standard Ruby
interpreter (often referred to as MRI Matz's Ruby Implementation).
This is a free port of the original SIL (SNOBOL4 Implementation Language)
macro version of SNOBOL4 (developed at Bell Labs) with the C language as
target.
SNOBOL4, while known primarily as a string language excels at any task
involving symbolic manipulations. It provides run time typing, garbage
collection, user data types, on the fly compilation. Its primary weakness
is its simple syntax, and lack of "structured programming" constructs.
However some consider the spareness of SNOBOL4 syntax a strength when
compared to some "modern" agglomerations such as perl.
