Modern Programming Pro

I daily have the chance to touch various programming languages.
However, new architecture appears at once when careless. The mounting situation of the latest each programming language was brought together as follows now.
I think that it should understand the method of mounting the developer barrel one and the latest architecture.

Perl::
If it becomes silent and the following are executed, it is safe.

        $ perl -MCPAN -e 'install Task::Catalyst'
        $ perl -MCPAN -e 'install Catalyst::Devel'
Python 
First of all, let's install it in the server that I manage while trac is practiced.
Enough if there is "easy_install".

PHP
Cakephp is a champion of the programming language to make WebApplication. It is an unshakable fact worldwide that PHP is used most.
Be not, and mount the remark of quickly!

Ruby 
Next, let's use merb when getting tired of rails. Now, I am constructing the system that combines merb with flex. Will you open it to the public here in the future? 

Java 
The appearance of Ruby on Rails seems to have compelled the paradigm shift to each language. A lot of Java developers shifted to Ruby by this. The Annotation is used Java5 since then, and the thing that the writing of a basic syntax changes stands out. 

Let's write something by Java after a long time. It is the shortcut to understanding.
