Sometimes people don’t know how to start learn ruby programming and still searching which book are suitable to them as a beginner. So I’m also as a beginner in ruby and rails programming, will suggest people to get Mr. Neighborly’s Humble Little Ruby Book as a reference to get start with ruby programming. This book will teach you the basic of ruby.
Quote from infoq.com
Mr. Neighborly’s Humble Little Ruby Book is a book about this fine language, but it is not a language book per se. It is perhaps best described as a mix between your favorite novel, your favorite Spanish textbook, and a Richard Simmons exercise video: it walks you through the very basics of working with Ruby, but by the end of it, you’ll no doubt be sweatin’ it to the oldies. It covers the base syntax of the language, including working with values, flow control, and object oriented programming, into some of the library functionality of Ruby, such as databases, web services, and string manipulation.
Expect this book to rock your world. Or at least teach you a programming language.

You want to make a copy of an existing object: a new object that can be modified separately from the original, Use Object#clone - makes a copy of the metaclass and instantiates the copy, instead of instantiating the object’s original class
example how to use clone :
s1 = 'foo' # => "foo" s2 = s1.clone # => "foo" s1[0] = ‘b’ [s1, s2] # => ["boo","foo"]

My friend ask me what is EdgeRails..this is what i found out :
‘EdgeRails’ is a term which means you are running a local copy of a developmental version of Rails(bleeding edge). It is an alternative to the more standard GemRails, which means you are running one of the stable releases.
‘Bleeding Edge‘ is a term that refers to technology that is so new (and thus, presumably, not perfected) that the user is required to risk reductions in stability and productivity in order to use it.
‘GemRails‘ is preferred method of installing Rails is through the packaging scheme RubyGems that makes it really easy to install libraries and keep them up to date
Advantage : get access to new features or bug fixes that are not in the most recent stable release. . Also EdgeRails allows you to run on computer without Rails installed
Disadvantage : developmental versions are not generally regarded to be stable. So it’s a tradeoff
How to use EdgeRails : embeded a (developmental) version of Rails within your application(copy into the vendor/rails directory) rather than using the version installed on your machine as a library
How to switch from Gemrails to EdgeRails :
rake rails:freeze:edge‘ from application home directory to unpack the latest edge rails into application vendor/rails directory. This embeds the Rails framework into your application by using Subversion (svn) to copy the files from the developmental source code repository (dev.rubyonrails.org) into your vendor/rails directoryrake rails:unfreeze‘.That command empties the vendor/rails directoryHow to install and managing EdgeRails visit http://www.sitepoint.com/blogs/2006/07/11/installing-and-managing-edge-rails/
