function my_custom_login_logo() {
    echo '<style type="text/css">
        h1 a { background-image:url('.get_bloginfo('template_url').'/images/login-logo.png) !important; }
    </style>';
}

add_action('login_head', 'my_custom_login_logo');

Using following code you can apply two colors alternatively to the page links. just edit the colors to apply different styles.

<ul class="page_navigation">
<?php
$pages = get_pages(array('sort_column'=>'menu_order'));
$totalpages=count($pages);
$count=0;
foreach ($pages as $pagg) {
$count++;
if($count%2!=0)
{
echo '<li class="odd">';
}
else
{
echo '<li class="even">';
}
echo '<a href="'.get_permalink($pagg->ID).'">';
echo $pagg->post_title;
echo '</a></li>';
}
?>
</ul>
<style type="text/css">
.page_navigation li.odd a
{
	color:red;
}
.page_navigation li.even a
{
	color:blue;
}
</style>

And if you want to display child pages of a specific page then just replace line

$pages = get_pages(array('sort_column'=>'menu_order','child_of'=>8));

change 8 with parent page id and display child pages of that parent.

and if you want to display child pages of current page then just add $post->ID instead of the page number.
like

$pages = get_pages(array('sort_column'=>'menu_order','child_of'=>$post->ID));

?>
<p><a href="<?php echo $author_url; ?>" title="View All posts By this author">View All posts By this author</a></p>

11. WordPress 3.0 Upgrade: What to Expect

With virtually any WordPress release (or the release of any open-source software, for that matter), there are bound to be bugs. And in virtually every case, easy fixes have already been found. Of course, there are also a number of things you can do prior to upgrading to prevent problems. Read on for some tips, and some of the common bugs you might run into.

12. Highlights of WordPress 3.0!.

Wordpress 3.0 was released to the public June 17th with a mountain of changes to it’s previous version. I have compiled my personal favorites below. For those of you not fully aware of the recent changes to WordPress, check out my favorites below:

13. 8 New Exciting WordPress 3.0 Features.

This WordPress 3.0 release is packed with tons of exciting features, like custom post type, better menu management, editor style and many more. It also comes with a new default theme – TwentyTen, that is compatible with most of the new features. Below I will highlight some of the keys features and how to implement them.

14. The Essential Guide to WordPress 3.0 Custom Taxonomies.

In general, taxonomies are used to arrange, classify and group things. By default, Taxonomies in WordPress are tags and categories that WordPress is using for the posts. Apart from these two, WordPress makes it possible for theme developers to create their own taxonomies which are created within the functions.php theme file. This is what we are going to cover today. We will learn how to work with Custom WordPress taxonomies.

15. WordPress: From Kubrick to Twenty Ten.

Kubrick, the default theme for WordPress since 2005, got many Web and open-source enthusiasts through some pretty tough times. Developers have modified it, bloggers have learned HTML and CSS on it, and designers have made it their go-to template for designing blogs of all sizes for clients.
Enter “Twenty Ten” the new default theme for WordPress 3.0, which is scheduled for an imminent release. Not only does it address general changes in Web standards and style guides, it takes into account the clamoring of designers who love WordPress but have had a hard time applying new principles to an older theme.

Here’s a list of the top seven most compelling features that could change the way you blog.

Code added to this post will calculate date difference in days, months, years format. So using this code you can calculate age by sending birth date as parameter. Or you can calculate difference between today’s date and any date in past.

function get_Age_difference($start_date,$end_date){
	list($start_year,$start_month,$start_date) = split('-', $start_date);
	list($current_year,$current_month,$current_date) = split('-', $end_date);
     $result = '';

    /** days of each month **/

    for($x=1 ; $x<=12 ; $x++){

        $dim[$x] = date('t',mktime(0,0,0,$x,1,date('Y')));

    }

    /** calculate differences **/

    $m = $current_month - $start_month;
    $d = $current_date - $start_date;
    $y = $current_year - $start_year;

    /** if the start day is ahead of the end day **/

    if($d < 0) {

        $today_day = $current_date + $dim[$current_month];
        $today_month = $current_month - 1;
        $d = $today_day - $start_date;
        $m = $today_month - $start_month;
        if(($today_month - $start_month) < 0) {

            $today_month += 12;
            $today_year = $current_year - 1;
            $m = $today_month - $start_month;
            $y = $today_year - $start_year;

        }

    }

    /** if start month is ahead of the end month **/

        if($m < 0) {

        $today_month = $current_month + 12;
        $today_year = $current_year - 1;
        $m = $today_month - $start_month;
        $y = $today_year - $start_year;

		}

    /** Calculate dates **/

    if($y < 0) {

        die("Start Date Entered is a Future date than End Date.");

    } else {

        switch($y) {

            case 0 : $result .= ''; break;
            case 1 : $result .= $y.($m == 0 && $d == 0 ? ' year old' : ' year'); break;
            default : $result .= $y.($m == 0 && $d == 0 ? ' years old' : ' years');

        }

        switch($m) {

            case 0: $result .= ''; break;
            case 1: $result .= ($y == 0 && $d == 0 ? $m.' month old' : ($y == 0 && $d != 0 ? $m.' month' : ($y != 0 && $d == 0 ? ' and '.$m.' month old' : ', '.$m.' month'))); break;
            default: $result .= ($y == 0 && $d == 0 ? $m.' months old' : ($y == 0 && $d != 0 ? $m.' months' : ($y != 0 && $d == 0 ? ' and '.$m.' months old' : ', '.$m.' months'))); break;

        }

        switch($d) {

            case 0: $result .= ($m == 0 && $y == 0 ? 'Today' : ''); break;
            case 1: $result .= ($m == 0 && $y == 0 ? $d.' day old' : ($y != 0 || $m != 0 ? ' and '.$d.' day old' : '')); break;
            default: $result .= ($m == 0 && $y == 0 ? $d.' days old' : ($y != 0 || $m != 0 ? ' and '.$d.' days old' : ''));

        }

    }

    return $result;

}

/* Call this function as */
$date_difference= get_Age_difference("2004-10-10",date("Y-m-d")); /* get_Age_difference(Birthdate,Todays_date) */
echo $date_difference;

Above code will output difference in format like
5 years, 10 months and 13 days old
