Programming Language Examples Alike Cookbook

This is a great project allocated at sourceforge, that i consult frequently while at work or doing some code at home.
Quoting the project description is the best way to describe it's aim.

"Following the great Perl Cookbook (by Tom Christiansen & Nathan Torkington, published by O'Reilly; you can freely browse an excerpt of the book here) which presents a suite of common programming problems solved in the Perl language, this project aims to implement the solutions in other programming languages."

At the project site you can consult lots of code examples on many languages, most of them are scripting languages, like Perl (obviously...), Python, Ruby, Groovy, Haskell and so on... Recipes like, reading file contents, string operations, hastables operations, regular expressions examples, etc.

And if you want to contribute in some way, like adding your favourite language, you can do it also by accessing the discussion lists.

You can access the site here and take a look at the great day-to-day examples, very useful in my opinion.
