Ruby on Rails - What is Ruby?

So, I am not just going to stop by providing the Ruby on Rails course structure.
I am here to start sharing the concepts what I understood about Ruby on Rails.
A gentle disclaimer, Nobody is perfect and in my attempt to become close to perfection I relied on world wide web to learn better and to understand the concepts clearly.

So let's start today with Introduction topic and discuss more on What is Ruby? If you are in hurry you can download What is Ruby?

Initially Some History about Ruby:

The language was created by Yukihiro "Matz" Matsumoto, who started working on Ruby on February 24, 1993, and released it to the public in 1995. "Ruby" was named as a gemstone because of a joke within Matsumoto's circle of friends alluding to Perl's name.

Some useful links that come handy when you are going through the course material:

Compilers : http://en.wikipedia.org/wiki/Compiler

Interpreters : http://en.wikipedia.org/wiki/Interpreter_%28computing%29

Object Oriented Programming : http://en.wikipedia.org/wiki/Object-oriented

Jargon to watch out:
Ruby, Interpreters, Compilers, Scripting Language, Compiled Language, Mixins, Operating System, Unix, Linux, Modules, Closures, Threads, Exceptions, Garbage Collectors,

Ruby is "an interpreted scripting language for quick and easy object-oriented programming".

Don’t be alarmed. We will take one by one:

Interpreted Scripting Language:

• Ability to make operating system calls directly
• Powerful string operations and regular expressions
• Immediate feedback during development
• Ruby programs can be executed from source code.(means to say need not be compiled)

Object Oriented Programming:

• Everything is an object
• Classes, inheritance, methods, etc.
• Singleton methods
• Mixin by module
• Iterators and closures

Portable:

• Runs on many different operating systems.
• Windows 95 through XP, Linux, UNIX...

Simple and Fast:

• Variable declarations are unnecessary (remember: everything is an object... including primitives)
• Variables are not typed
• Syntax is simple and consistent (like you are expressing something)
• Automatic memory allocation and garbage collection

More...

• Exception processing model
• Dynamic loading
• Threads

Ruby on Rails - Course structure

You find lot of materials, websites and many articles where you get information about Ruby and Ruby on Rails.
Well, do not get over loaded with the information. If anybody is serious about learning and practicing Ruby on Rails, can make use of the below course structure. This course structure, I had just jotted down to train freshers and friends whoever interested to know more about RoR.
Note: This structure is framed based on

1. my experience in RoR.
2. my previous session on RoR gathering.
   

If anybody is interested can contact me for more information.

Prerequisites for the RoR Course:
The course is structured keeping in view of less experienced/freshers in the industry. So considereable time is given for all introductory topics.
However, having knowledge/experience is an added advantage:

1. Exposure to any of the programming languages (c,c++,c#,java...)/Scripting languages(perl, php, smalltalk...).

2. Overview on how web application works.

3. Understanding of the necessity of Data models, Configuration Management.

4. Necessary tools/IDE's (Eclipse IDE, notepad...)

5. Good Analyzing skills.

6. Web Technologies (HTML, JavaScript, CSS, XML, )
