Preferred IDEs for various programming languages

so............ over the last one month i had been trying out several IDEs (Integrated Development Environments) for different kinds of programming.... and here is what i figure out to be the best IDEs for the various programming languages. My judgement is based on:

• quickness of code-completion suggestions, 
• quick search through Docs, 
• ease of program execution and deployment
• ease of handling GUI (graphical user interface)
• ease of installation of plugins or add-ons

Programming Language	Preferred IDE
Java        PHP	Net Beans
Android	Eclipse
Adobe AIR	Aptana

Problem with displaying joomla correctly on XAMPP in Linux

i have used Ubuntu 10.04 Lucid Lynx.
i had used the default full installation of XAMPP for Linux 1.7.3a.

i had coded PHP applications for quite awhile and everything worked great....... but when i installed Joomla - a leading Content Management System on PHP - on my localhost, i got some gibberish nonsense like this...... full of this error and that error

i searched the net for answers but found no source helpful...... that's why putting the solution to this problem up on my blog.

Removing the 'index.php' from the URL of a codeigniter site

UPDATE (9th May 2015): at the time of writing this article, codeigniter was on version 1.7 I guess. Now, in codeigniter version 2.2.2, the official documentation of Codeigniter shows how to achieve this goal very easily. You can refer to the "Removing the index.php file" section in http://www.codeigniter.com/userguide2/general/urls.html page.

By default, the index.php file will be included in your URLs:
example.com/index.php/news/article/my_article
---
You can easily remove this index.php from displaying in the url by using a .htaccess file in your 'codeigniter' root folder and make it look like: example.com/news/article/my_article

Notice the absence of anything infront of the (.) dot in the filename of .htaccess file

Here is an example of such a .htaccess file.
