Utilizing an EAVmodeling pattern allows for unlimited attributes on any product, category, customer, or order.  As is often  the case, the cost of flexibility is complexity EAV depletes a programmer’s ability to write ad-hoc queries against the data.

An understanding of EAV principles and how they have been modeled into Magento is highly  recommended before making changes to the Magento data or the Magento schema. But a detailed tutorial on the EAV database model  missing in  magento documentation.

EAV  modelling is consist of as  “vertical” modeling instead of “horizontal” modeling of columns in a database table. Instead of a table consisting of a number of columns, denoting attributes of a conceptual piece of data, the attributes are stored in one column of a separate table.

Let us consider a traditional user table as shown below

In an EAV database modelling, one conceptually records the data as three columns.
1)The entity: An entity is a core thing that is being modeled. It more like an Object like user,product etc.. For the above Example we can defile the user entity table ‘user_entity’ as below

2)The attribute or parameter: Entity attributes work much like a regular property of an object. The user ‘eav_attribute’ table  will be like below

3)The value: This is the value of each attribute. For the user value table ‘user_varchar’ will look like below

As you can see from looking at the above tables, adding a new attribute to a user simply involves adding a new record in the eav_attribute table. Adding a new attribute does not involve altering tables to add any new columns.This will make the objects or entities to easily manage adding new attributes to most parts of the system, while keeping the database schema consistent across installations.

function jquery_init() {
     if (!is_admin()) {
	wp_enqueue_script('jquery');
     }
}
add_action('init', 'jquery_init');

For plugin development, add the code in your plugin file, otherwise, add this code to your theme’s functions.php file. The is_admin() check is to prevent script queuing on your admin pages.

If you want to load  jQuery from the Google AJAX Library, you can use the following code.

function jquery_init() {
  if (!is_admin()) {
	wp_deregister_script('jquery');
	wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js', false, '1.3.2');
	wp_enqueue_script('jquery');
  }
}
add_action('init', 'jquery_init');

There are a number of advantageous why you would want to use the Google AJAX Library to load jQuery, but remember, Google has been down before, so be ready to comment out the first two lines if necessary.

The problem occurs because magneto could not store cookies. We run it as localhost and localhost is not true domain but to store cookies we need a domain. That’s why login stops without saying any word.

When I tried this  in different browsers  I found that we can login the admin page in safari without doing any change but can’t login using  firefox or Internet explorer.  We can solve the problem in many ways.

Solution 1. Creating a virtual host

We can solve the problem by simply setting up a virtual host like http://magento.local I fixed the problem by this method since it seems to be very easy and reliable.
For setting up a virtual host for magento just edit the httpd.conf and add the following line to the end of the file

Then edit the /etc/hosts in linux or C:\WINDOWS\system32\drivers\etc\hosts in Windows and add the following to the file

Solution 2. Change the localhost url to IP

Change http://localhost/magento/index.php/admin to http://127.0.0.1/magento/index.php/admin. But this will not work for all the cases

Solution 3. Comment some line of code

Edit app\code\core\Mage\Core\Model\Session\Abstract\varien.php and Comment the following lines (may be at line 78…);

The site says that, Due to traffic jams, rains and Trivandrum’s trademark Secretariat marches, actual timing may differ a bit, but please continue supporting KSTRC by using this service regularly, even if a bit inconvenient in the beginning. And if you can, request the staff to introduce more services during our peak hours. exhorting all techies to make use of the bus service to the most.
The site published the following detailed time schedule for the Low Floor bus  schedule in the Kaniyapuram to City route via Technopark.

I have mixed the script with Jquery. We can use Jquery’s bind method to bind the event but using bind we can’t handle the event properly. Using the following script we can easly customize the confirmation message and also it will work on IE and most of the common web browsers.

Actually jquery is not having any functional role in the script but using the following script we can avoid inline scripting and our code will look nice.

$(window).load(function() {
	window.onbeforeunload = navigateAway;
});
 
function navigateAway(e){
	var message = "Your confirmation message goes here.",
	e = e || window.event;
	// For IE and Firefox
	if (e) {
		e.returnValue = message;
	}
	// For Safari
	return message;
}

They say that 17 years ago, one man was shot dead behind this rock as he was hidden there. This encounter happened in the month of April 1989. You can see the fresh blood stains on the rock. Most surprisingly, when the rock raises from the ground, these stains become darker, fresher and wet. Local residents tried to wipe off the stains several times, but after some time it appears again on the rock automatically. …. Isn’t it astounding?  “

When I read it I understood  that it must be a fake picture and fake information so I started to search on google but I didn’t get any real pictures of the rock. But found one Haleem Qureshi Civil Engineer from Saudi Arabia knows the real fact and has the real pictures of the rock. He sent me the  real pictures and shared the real story of the Surprising Rock in Saudi Arabia with me

The following are two fake pictures of rock.

But we can see the original Pictures of rock present at Al-Hassa ,City located at east west of Riyadh.

Another close picture of the Surprising Rock  from different angle and the supports are eliminated by photoshop.

Following is the same rock but has changed with different style with Photoshop. The Photoshop expert has put  sheep under the rock and rock has risen from one side.

There are many rocks available in Saudi Arabia having with little support. The surrounded area under the rocks has vanished through heavy sand storms & only small supports have remained.   See the example below.

The conclusion of whole attached detail is,there are many rocks available in that region but all rocks have little support under the rocks .These rocks are not hanging.But it can slipped any time when the small pointed support will be removed by heavy desert sand storm.Local authorities have already made plan to move these rocks at suitable place to avoid any accident due to slipping of these rocks.

After the flagging-off ceremony, the Chief Minister, Union Minister of State for External Affairs Shashi Tharoor, several Ministers and legislators and officials of the Kerala State Road Transport Corporation (KSRTC) boarded an orange-red Volvo bus for a ride from the Central Stadium. As the bus was overcrowded, the Chief Minster and some others alighted at the gate.

The KSRTC, which is executing the purchase and maintenance part of the city bus service proposed under the Jawaharlal Nehru National Urban Renewable Mission (JNNURM), has given the purchase order for 30 low floor A/C buses and 120 semi-low floor non-A/C buses for Thiruvananthapuram.
