I’m figuring out how to change this behaviour in Firefox, by changing the deafult search engine to Google. Later, I found out that it is not available as a normal setting like in Chrome.

How to?

To change the default search engine in Firefox it will require you to…

1. Enter “about:config” in the URL bar and a warning will prompt about your warranty.
2. Hit the “I’ll be careful, I promise” button.
3. Search for “keyword.url” preference name.
4. And change the value to “http://www.google.com/search?ie=UTF-8&oe=utf-8&q=”.
5. Accept the changes.

That’s it, type in search keyword again on the URL bar and it will lead to Google search results. For detailed information about keyword.url in Firefox check MozillaZine.

XML-RPC?

XML-RPC is a remote procedure call (RPC) protocol which uses XML to encode its request methods and uses HTTP in sending its requests to a remote server implementing XML-RPC. In this transport mechanism, the client that wants to call a remote method from the server will create request parameters in the form of XML and sends it via HTTP. On the server end, it will analyze and perfrom the request method and send back response to the client in XML format.

XML-RPC in WordPress

WordPress implements XML-RPC which allows client  to requests operation on the WordPress installation remotely. Valid operation/methods are listed in WordPress API. Using XML-RPC in WordPress allows developer to create blogging clients or other implementation such batch processing posts remotely.

XML-RPC Library in WordPress

As of this writing WordPress ships with the Incutio XML-RPC Library, and the file resides in/wp-includes/class-IXR.php. And its implementation of the server normally accessed through http://yourwordpresssite/xmlrpc.php or by checking through the sites header and look for <link rel="pingback ...> tag. This functionality is turned on by default since WordPress 3.5.

Testing Demo Methods in WordPress

To get started in creating a request to XML-RPC server, WordPress provide tow test methods to verify if your server is working correctly.

• demo.sayHello – Sends back “Hello!” message
• demo.addTwoNumbers – Add two given Number and sends back the result

Using the delievered XML-RPC library, requesting the demo.sayHello method can be done as the following code. The testing performed on my local WordPress installation.

<?php
require_once('class-IXR.php');
$client = new IXR_Client('http://mywordpress/xmlrpc.php');
$client->query('demo.sayHello');

print $client->getResponse();
?>

If the above code will send back Hello! message, then the server works correclty. Then, for requesting for the demo.addTwoNumbers can be done as the following code.

<?php

require_once('class-IXR.php');
$client = new IXR_Client('http://mywordpress/xmlrpc.php');
$client->query( 'demo.addTwoNumbers', array( 33, 22 ) );
print $client->getResponse();

?>

And will get a 55 response from the server.

Creating Posts through XML-RPC

And now, let’s create a new post to our WordPress blog by sending request for the wp.newPost (see API) method. The following code tested on my local wordpress installation.

<?php

require_once('class-IXR.php');
$client = new IXR_Client('http://mywordpress/xmlrpc.php');
$client->query('wp.newPost', array(
    0,
    "adminuser",
    "adminpassword",
    array(
        'post_status'  => 'publish',
        'post_title'   => 'Remote Post',
        'post_content' => 'The quick brown fox jumps over the lazy dog',
        'terms_names'  => array(
            'category' => array(
                'XML-RPC'
            ),
            'post_tag' => array(
                'xml',
                'rpc'
            )
        )
    )
) );
print $client->getResponse();

?>

The above code will return the post id, and it means that posts created successfully. To check the output visit the your WordPress site.

And I would like to manipulate the result into 2 rows as follows:

Create Sample Table
To create our test table, execute the following SQL commands:

CREATE TABLE "TEST_ITEMS" ("ITEMS" NUMBER) ;
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (101);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (102);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (103);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (104);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (105);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (106);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (107);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (108);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (109);
Insert into HC4320_MODTEST_RDB.TEST_ITEMS (ITEMS) values (110);

Transformations
Create a simple query and add a row_id for each returned rows.

select items, row_number() Over (order by items) row_id
from test_items

Using the result above add a CAT row using the decode command which will identify the column classification for each rows  and a GRP as our group id.

Select items, decode(mod(row_id,2), 1, 1, 0, 2, null) cat, decode(mod(row_id,2),0,row_id-1,row_id) grp
From
(
  select items, row_number() Over (order by items) row_id
  from test_items
)

Then  this will result to classify by group the values for 1st and 2nd row. Using the  following query below.

Select grp, decode(cat,1,items) row1, decode(cat,2,items) row2
from
(
  Select items, decode(mod(row_id,2), 1, 1, 0, 2, null) cat, decode(mod(row_id,2),0,row_id-1,row_id) grp
  From
  (
    select items, row_number() Over (order by items) row_id
    from test_items
  )
)

Finally, filter out null values.

select max(row1), max(row2)
from
(
  Select grp, decode(cat,1,items) row1, decode(cat,2,items) row2
  from
  (
    Select items, decode(mod(row_id,2), 1, 1, 0, 2, null) cat, decode(mod(row_id,2),0,row_id-1,row_id) grp
    From
    (
      select items, row_number() Over (order by items) row_id
      from test_items
    )
  )
)
group by grp
order by grp

There are other ways to do it, and I would like hear some your thoughts on this.

The service made it debut back in 2005, it allows anyone with a Google account the ability to aggregate and read RSS feed subscriptions in one place. Since then it undergone some development to enhance user experience. And due to the decline of number of usage, Google decided to stop and put their focus on other products.

Google give 3 months for the user to find other alternative. Several substitutes are known, such as Feedly, The Old Reader and NewsBlur. And if you want to export all your reader data (How?) Google provide a method for smooth transistion.

How it works:

$email = is_email('admin@lo^calhost.com');  //contains invalid character
// $email variable is set to false.

$email = is_email('admin@localhost.com');
// $email variable now is set to 'admin@localhost.com'

And  when adding a leading zeros is necessary in displaying result, such as to display ’2′ as ’02′ in order to maintain number of digit be displayed. WordPress provide a zeroise() function to handle this. Which takes the following parameters:

$number – Number to append zeros
$threshold – The number of digits

For example to display ’2′ as ’02′:

<?php
  $number = 2;
  echo zeoise($number, 2); //display 02
?>

However, when the number is large enough than threshold, then no zeros will be appended.

var http = require('http');
var server = http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write("<!DOCTYPE html>");
  res.write("<html>");
  res.write("<head>");
  res.write("My HTTP Server");
  res.write("</head>");
  res.write("<body>");
  res.write("Hello World!");
  res.write("</body>");
  res.write("</html>");
  res.end();
});
server.listen(8080);
console.log('Server listens at port 8080');

We now have a basic code to start our server. By this time we created our server to return “Hello World!” for every request. To start our server, in the command line type in…

node myhttpserver.js

If everything works correctly, we will see a message that our server is listening. Then, the next thing to do is to launch our web browser and access our server through the following address

http://localhost:8080 or http://127.0.0.1:8080
