To restart apache httpd server – # service httpd restart

To stop apache httpd server – # service httpd stop

Other putty/ssh command
To check server memory – $ vmstat OR #free OR #free -m

Q1. Download from live server to localhost. When view homepage, it is different result from what we seen from server.
A1: Try to clear the cache by going to drupal admin: Site Configuration -> Performance. Click the clear cache button to clear.

Q2. When clear the cache, it displays error message regarding the memory exhausted.
A2: This is due to memory limit when you want to clear the cache. Go to the localhost’s apache php.ini do configuration. (php.ini file can be found at root/xampp/apache/bin)
Change the line “memory_limit = 32M” to “memory_limit = 128M” so that system has more memory to clear the cache. Restart apache server.
Return to drupal admin and select menu Site Configuration -> Performance. Click the clear cache button to clear.

YUI 3 is still under beta version, therefore, most of the modules and functions are not available. You have to use those functions/modules provided by YUI 2.7. The YUI 2.7 code is solid and firm can be used in YUI 3.0 or the future next newer version.

Before we start, first of all, we go to the website to download the whole frameworks: http://yuilibrary.com/downloads/#yui3.

After downloaded, let’s get started!

1. In your code you should add this line to enable the YUI frameworks:

This file contains YUI class, with its constructor and core functions, which is to performs most basic functions.

2. YUI 3.0 code is more neat, and compact, compare to YUI 2.7. For instance, when you want to use some certain modules from library, you just code this format:

YUI().use(”[-- MODULE NAME(S) --]“, function(Y) {}, which the module names are actually the folder names found in YUI root files. For example:
YUI().use(dd-drop’, ‘node’, ‘io’, function(Y) {start code here}; you can implement classes & functions in drop, node & io modules. The function “use” is actually from its core library.

3. To create new object/instance:
var A = new Y.(module class)({ properties });

4. In YUI, to create your function definition, you can code like this:
var functionA = function (e){ your code is here };

When you want to call the function definition:
Y.on(”click”, functionA);

Note that, actually Y.on can be work more arguments than it show as above.
Y.on([-event name-], [-function-], [-element(s)-], [-object-], [-argument-])

5. YUI provides easier solution for us to get attributes value. For example when we want to get the element’s ID, we usually use getElementById(). In YUI, Y.Node.get(’#ID name’); ( make sure you add the Node modules in YUI().use() ). Of course, getElementById still can implement in YUI library. There are a few ways we can do for get function:
(a) obj.get(’node’).setStyles({ opacity: ‘1′});
(b) Y.Node.get(’#IDName’).get(”your attribute like name, value etc”)

Example 1 (SELECT statement)

$db =& JFactory::getDBO();
$query = “SELECT * FROM #__mytable”;
$db->setQuery( $query );
$db->query();

To retrieve 1 data from mysql use this code below:

$obj_row = $db->loadObject();

This will only return the objects. You need to use foreach to get the data.

For example:

foreach($obj_row as $a){

echo $a->id;

}

Tips: var_dump() would be an excellent assistance to know how the raw data is stored.

To load the lists of data from a table,  we do not use $db->loadObject();. Instead we use $db->loadObjectList();

Example 2: To insert/update data

$db =& JFactory::getDBO();
$query = ” (update/insert mysql query statement)”;
$db->setQuery( $query );
$db->query();
OR

$__data =new stdClass();
$__data->id = null;
$__data->field1 = var1;
$__data->field2 = var2;
$__data->field3 = var3;
$__data->field4 = var4;
$__data->field5 = var5;
$db = JFactory::getDBO();

$db->insertObject( ‘#__mytable’, $__data, id );   (if you want to insert data)

$db->updateObject( ‘#__mytable’, $__data, id );   (if you want to insert data)

If we use insertObject/updateObject then we no need to put the mysql command, and the code would looks neater.

All the functions which are to manipulate data can be found in this class: JDatabase, which located at <root>/libraries/joomla/database/database.php

First of all, add this JHTML::_(’behavior.calendar’); code line in your class view (view.html.php) extends JView.

Then go to your form page include this:

<input type=”text” name=”start_date” id=”start_date” size=”20″ maxlength=”19″ value=”" />

<input type=”reset” value=”…” onclick=”return showCalendar(’start_date’,'%Y-%m-%d’);” />

Then it should be done.

Meeting old friends made me felt in university life again.

The exciting and happy feeling leave so fast.

Hope to meet them again soon.

Blogger generally will create the new files once you posted your subject(s). When your posts are to begin to grow eventually, your files will be flooded in one folder. You will find hard to locate & maintain your files in your folder. Therefore, I had made my mind to switch my blog tools to wordpress, which all the comments, posts, etc are manage in the database. It will be more organized.

However, blogger is still excellent criteria to be used for the new starters to establish their blogs.

Well, here is the useful steps share by benfrain and it is really helpful to me.

Step 1: Go to your desired path folder like shown on below image.

From the icons you can see the green tick on one folder which means this folder is subversioned (svn-ed).

Step 2: Click the folders button beside the Search button. You will see the list of folders and files listed on your left.

Step 3: Drag the svn folder to your directories on your left to your same folder as shown below. While drag the folder, make sure you use right-click. It will show the options. Choose the option “SVN Export versioned items here”. Then your task is already done.

Step 4: You can see your all hidden .svn files has already removed, which means that you already unversioned your work files.

My 1st best suggestion; manually check the disk volume.

1. Start->My Computer
2. Select the Drive you want to perform the check by right click, select properties.
3. Choose the tools tab and then press the Check Now button.
4. Check 2 checkboxes then proceed the check.
5. It may take some minutes to be done.
6. Restart your computer and see if there is still got the auto check disk in windows.

If the 1st suggestion is not the way, there is still got another way to solve it.

2nd suggestion; manually cancel the auto check disk by run command.

1. Start-> Run…
2. Type this command chkntfs /x c: . The /x probably means cancel the desired auto check disk, where c: is the drive to be cancel the auto check disk. You will see the command prompt appear few seconds and disappear.
3. When it is disappear it is done.
4. After you perform this task, the cpu register changed. You can go to the registry editor to view by press Start-> Run… , type regedit. Then find the path HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\Session Manager.
5. You can see that there is the registry BootExecute changed its data to autocheck autochk /k:c *.
6. Restart your computer and see the results.

Thanks to Raymond that I finally settle this problem.
