Open index.php file of your theme and replace the existing loop with:

<?php
if (have_posts()) :
     while (have_posts()) : the_post();
         $expirationtime = get_post_custom_values('expiration');
         if (is_array($expirationtime)) {
             $expirestring = implode($expirationtime);
         }

         $secondsbetween = strtotime($expirestring)-time();
         if ( $secondsbetween > 0 ) {
             // Enter your post display code after that.
             the_title();
             the_excerpt();
             // Post display code ends here.
         }
     endwhile;
endif;
?>

Now while creating a post to set it’s expiration date/time create a custom field with name(key) expiration and set your expiration time as value in this format mm/dd/yyyy 00:00:00.

	} else {

	if (is_array($expirationdate)) {
	$expirestringarray = implode($expirationdate);
	}
	$expirestring = str_replace("/","",$expirestringarray);
	} //else
	if ( $expirestring > $currentdate ) {
             // Enter your post display code after that.
             the_title();
             the_excerpt();

While writing a post look for Publish module usually located at extreme right on the screen, click on the Edit link next to Visibility option there check “Stick this post to the front page” option and That’s it!

Checkout this screen cast video for better understanding:

P.S. Sticky post feature was introduced in Wordpress 2.7, So you need to have Wordpress 2.7 or newer to use this feature.

function time_ago( $type = 'post' ) {
	$d = 'comment' == $type ? 'get_comment_time' : 'get_post_time';
	return human_time_diff($d('U'), current_time('timestamp')) . " " . __('ago');
}

Now place the following snippet in either single.php or comments.php (wherever you want to show it) within loop.

<?php echo time_ago(); ?>

Thanks to Chris for sharing this code.

if (!current_user_can('edit_users')) {
	add_action('init', create_function('$a', "remove_action('init', 'wp_version_check');"), 2);
	add_filter('pre_option_update_core', create_function('$a', "return null;"));
}

Thanks to Jeff for sharing this tip.

UPDATE wp_users SET user_pass = MD5( 'new-password' ) WHERE user_login = 'admin-username';

Change new-password with your new desired password and admin-username with your blog admin username for which you want to change password.

function bitlyLink($url) {

$username = "Bit.ly Username"; // Your Bit.ly Username
$api = "Bit.ly API Key"; // Your Bit.ly API Key

$data = file_get_contents("http://api.bit.ly/shorten?version=2.0.1&format=xml&longUrl=".$url."&login=".$username."&apiKey=".$api);

$xml = new SimpleXMLElement($data);
$shortlink = $xml->results->nodeKeyVal->shortUrl;

return $shortlink;
}

Don’t forget to add your Bit.ly Username and API key (get API key)

Now add the following code within loop in single.php file of your theme.

<?php
$bitlyLink = bitlyLink(get_permalink($post->ID));
echo 'Short Link for this post: <a href="'.$bitlyLink.'">'.$bitlyLink.'</a>'
?>

P.S. All the links will generate within your account so you can track them all by logging in to your Bit.ly account.
