MPI Ruby is a Ruby binding of MPI. MPI Rubys primary goal in making this binding was to make the power of MPI available to Ruby users in a way that fits into the languages object oriented model.
In order to do this, the buffer and datatype management necessary in the C, C++, and Fortran bindings have been removed. What this means is that MPI Ruby allows you to treat objects as messages.
MPI Ruby also aims to be a complete binding to MPI in that it offers access to nearly all functionality of MPI. While there is not a one-to-one correspondence to functions and constants in the Ruby and C/C++/Fortran bindings, all of the communication and topology features are available.
There are fewer methods in the Ruby binding than there are functions in the C/C++/Fortran bindings, but this is mainly due to the fact that the programmer no longer needs to deal with buffers and datatypes.

JRuby is a pure Java implementation of the Ruby interpreter, being developed by the JRuby team.
JRuby is free software released under a dual LGPL/GPL license.
JRuby is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application.
Main features:
- Ruby 1.6.7 compatible interpreter. (Not all builtin classes are supported yet!)
- Working towards full compatibility with Ruby 1.8.1.
- Support for scripting Java classes and interfaces in JRuby.
- Bean Scripting Framework (BSF) support.
Enhancements:
- Overall performance is 50-60% faster than 0.9.0.
- Improved Rails support.
- A new syntax for including Java classes into Ruby.
- A new interpreter design.
- Refactoring of the method dispatch, code evaluation, and block dispatch code.
- Parser performance enhancements.
- Rewriting of Enumerable and StringScanner in Java.
- New experimental syntax for implementing interfaces.
- 86 Jira issues have been resolved since 0.9.0.

ruby-ircd is an IRC daemon implementation. ruby-ircd extends the webrick generic server.
Currently, it only supports minimal facilities like creation of rooms and private messaging between users and rooms.
Enhancements:
- Compatibility fixes were made for different clients. AWAY, LIST, TOPIC, WHOIS, and VERSION were implemented.
- The code was cleaned up.

ruby-rpm project provides bindings for accessing RPM packages and databases from Ruby. It includes the low-level C API to talk to rpm as well as Ruby classes to model the various objects that RPM deals with (such as packages, dependencies, and files).

Installation:

De-Compress archive and enter its top directory.

Then type:

$ ruby install.rb config
$ ruby install.rb setup
$ su
# ruby setup.rb install

You can also install files into your favorite directory by supplying install.rb some options. Try "ruby setup.rb --help".

Usage:

require rpm

FXRuby project is a Ruby extension module that provides an interface to the FOX GUI toolkit.
Enhancements:
- This release fixes a number of recently reported problems, and adds preliminary support for keyword-style arguments.

Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many features to process text files and to do system management tasks (as in Perl). It is simple, straight-forward, extensible, and portable.
Main features:
- Ruby has simple syntax, partially inspired by Eiffel and Ada.
- Ruby has exception handling features, like Java or Python, to make it easy to handle errors.
- Rubys operators are syntax sugar for the methods. You can redefine them easily.
- Ruby is a complete, full, pure object oriented language: OOL. This means all data in Ruby is an object, in the sense of Smalltalk: no exceptions. Example: In Ruby, the number 1 is an instance of class Fixnum.
- Rubys OO is carefully designed to be both complete and open for improvements. Example: Ruby has the ability to add methods to a class, or even to an instance during runtime. So, if needed, an instance of one class *can* behave differently from other instances of the same class.
- Ruby features single inheritance only, *on purpose*. But Ruby knows the concept of modules (called Categories in Objective-C). Modules are collections of methods. Every class can import a module and so gets all its methods for free. Some of us think that this is a much clearer way than multiple inheritance, which is complex, and not used very often compared with single inheritance (dont count C++ here, as it has often no other choice due to strong type checking!).
- Ruby features true closures. Not just unnamed function, but with present variable bindings.
- Ruby features blocks in its syntax (code surrounded by { ... } or do ... end). These blocks can be passed to methods, or converted into closures.
- Ruby features a true mark-and-sweep garbage collector. It works with all Ruby objects. You dont have to care about maintaining reference counts in extension libraries. This is better for your health.
- Writing C extensions in Ruby is easier than in Perl or Python, due partly to the garbage collector, and partly to the fine extension API. SWIG interface is also available.
- Integers in Ruby can (and should) be used without counting their internal representation. There *are* small integers (instances of class Fixnum) and large integers (Bignum), but you need not worry over which one is used currently. If a value is small enough, an integer is a Fixnum, otherwise it is a Bignum. Conversion occurs automatically.
- Ruby needs no variable declarations. It uses simple naming conventions to denote the scope of variables. Examples: simple var = local variable, @var = instance variable, $var = global variable. So it is also not necessary to use a tiresome self. prepended to every instance member.
- Ruby can load extension libraries dynamically if an OS allows.
- Ruby features OS independent threading. Thus, for all platforms on which Ruby runs, you also have multithreading, regardless of if the OS supports it or not, even on MS-DOS! ;-)
- Ruby is highly portable: it is developed mostly on Linux, but works on many types of UNIX, DOS, Windows 95/98/Me/NT/2000/XP, MacOS, BeOS, OS/2, etc.

Whois Ruby provides a Ruby class to handle whois requests.

Whois Ruby is a Ruby class to obtain whois request information when provided with an IPv4/IPv6 address or hostname. It sends a whois query to a suitable server.
