The algorithm shown in the movie looked a bit like this:

• Ea = 1 / (1 + 10 ^ ((Rb-Ra)/400))
• Eb = 1 / (1 + 10 ^ ((Ra-Rb)/400))

Here is something a bit more practical in the form of a PHP script:

/**
 * Calculates odds of winning or new score.
 * New players start on 2000 points.
 *
 * @param int $player1 Player 1 Score
 * @param int $player2 Player 2 Score
 * @param int $result  Determine the result
 *                     0 = Calculate Odds (%)
 *                     1 = Player 1 Won
 *                     2 = Player 2 Won
 *                     3 = It's a Draw
 */
function calculateRank($player1, $player2, $result=0)
{
	$odds_p1 = 1/(1+pow(10,(($player2-$player1)/400)));
	$odds_p2 = 1/(1+pow(10,(($player1-$player2)/400)));

	if ($result==0)
		return array('player1' => $odds_p1*100, 'player2' => $odds_p2*100);

	$result_p1 = ($result==1) ? 1 : (($result==2) ? 0 : 0.5);
	$result_p2 = ($result==1) ? 0 : (($result==2) ? 1 : 0.5);

	$score_p1 = $player1 + (32*($result_p1-$odds_p1));
	$score_p2 = $player2 + (32*($result_p2-$odds_p2));

	return array('player1' => $score_p1, 'player2' => $score_p2);
}

Enjoy!

        $calcStart = 0; // Level 1 Start XP

        $calcInc = 0;   // Increase by extra how many per level?

        /* Calculate Level */
        $myLevel = 0;
        $calcCount = 0;
        do {
                $calcCount = $calcCount+1;
                if ($calcCount % 2 == 0 ) { $calcInc = $calcInc + $calcLevel; }
                if (($myPoints < $calcEnd) && ($myPoints >= $calcStart)) { $myLevel = $calcCount; $myStart = $calcStart; $myEnd = $calcEnd; }
                $calcStart = $calcEnd;
                $calcEnd = $calcEnd + $calcInc;
        } while ($myLevel == 0);
        $myLevel--;

        /* Calculate Percentage to Next Level */
        $myPercent = (($myPoints - $myStart) / ($myEnd - $myStart)) * 100;
        $myPercent = round($myPercent);
        if ($myPercent == 0) { $myPercent = 1; }

        return array('percent'=>$myPercent,'level'=>$myLevel);
}

Please excuse the primitive logic and bad variable naming, this was written many years ago.

1. What is it?
2. What do I have to do?
3. What do I get?

Anything else should only relate to the above, for example if there is a potential risk of wasting resources, like the user’s precious time, reinforce the cost:reward or illustrate that other people have taken the risk before them, like the peer pressure effect from a Facebook Like Box.

It is important to address this problem as early as possible since links can be created outside the scope of your website and the search engines may already have indexed your website under both addresses, this cannot be changed that easily.

The solution is simple: force a 301 redirect for all http requests that are going to the incorrect website URL.

Redirect www.yourdomain.com to yourdomain.com

RewriteEngine On
RewriteBase /
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !^yourdomain.com$ [NC]
RewriteRule ^(.*)$ http://yourdomain.com/$1 [R=301,L]

Redirect yourdomain.com to www.yourdomain.com

RewriteEngine On
RewriteBase /
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !^www.yourdomain.com$ [NC]
RewriteRule ^(.*)$ http://www.yourdomain.com/$1 [R=301,L]

Break it down

Line 1 -2: Instructs apache to handle the current directory and enable the rewrite module.

Line 3: Specifies that this rewrite should be ignored for HTTPS protocol. (edit: Thanks Al)

Line 4: Specifies the condition for when the rule following should be triggered. For example, when the condition of HTTP_HOST (website URL) is not (specified with “!”) the correct website url respectively starting (^) and ending as a hostname ($). The final [NC] tag specifies that the hostname is not case sensitive.

Line 4: Describes the action that should be performed after the above condition is met. The first segment of the rule ^(.*)$ is an important and special one, this captures the requested url without the domain as a variable ($1). The second segment defines the target of the rewrite rule, the final destinaton for the redirect. The tags at the end will determine how the redirect is performed, in this case we are performing a permanent redirect (R=301) and this is the last rule for the rewrite (L) so a result is expected.

Being unable to find a Dreamweaver color scheme for Netbeans code editor anywhere, this one was built from scratch today using exact color codes from Dreamweaver.

The Netbeans theme also takes a slight influence from Visual Studio’s default colors.

Mmmmm now that’s easy on the eyes.

• Download Netbeans/Dreamweaver color scheme

<?php
$parent_id = ($post->post_parent)?$post->post_parent:$post->ID;
$children = wp_list_pages("title_li=&child_of=".$parent_id."&echo=0");

	<h3><?php echo get_the_title($parent_id)?></h3>

Beautifully simple.

“They always…”

“That happened to me because…”

“They are…”

They are a person. That happened to you because it happened. They never more than they always.

• clean up, convert, recount, reset, recompile, recreate, repopulate the ID column for every entry
• modify the auto increment counter for the table

It is important to note this script should not be used on tables with cross referenced identifiers meaning if a different table relies on the IDs of the modified table it will potentially break the references as a result of assigning the new IDs.

The code might also be useful for other purposes, such as cleaning up CMS page orders or providing a package with clean sample data.

Example

If your table looks like this:

ID  |  Name
-------------
1   |  Wally
4   |  Sally
6   |  Harry
12  |  Mandy

This script will modify your table to this:

ID   |  Name
-------------
1    |  Wally
2    |  Sally
3    |  Harry
4    |  Mandy

mySQL Script

-- your_table: The table to modify
-- id: The id field/column to reset

SET @num := 0;
UPDATE your_table SET id = @num := (@num+1);
ALTER TABLE your_table AUTO_INCREMENT =1;

Places have different populations or “markets”. If you were a gay man the possibility of finding another gay man is greater if you lived in the city than a rural town because it has a much larger market. So if you define opportunity as meeting people who share your interests, beleifs, hobbies or whatever then a place with a huge population will have more opportunity.

For some the “right people” might only be found in rural areas in which case it isn’t a numbers game at all, it is about being in a rural place. For others the definition of opportunity might be solidarity which equally favours rural areas as to receive a less distracting environment. However this is all just subjective meaning, or more strongly a belief, often stemmed from a perceived or actual threat.

Meaning and beleifs are just that. Yours don’t mean much to anyone else, they only mean something to you. You could share a convincing story about how you came to that conclusion but that’s all it is, a story you tell yourself. It doesn’t make it real to anyone else but you.

“Oh it’s society, it’s the economy, it’s the previous generation.”

Complaining, blaming, justifying, “carrying on” are all actions that attempt to avoid the responsibility of being wrong and/or looking bad. People who persist in this are resigned from life and just waiting to die. This is the easy way out most people take but it comes at the cost of happiness.

To be happy at a basic level at least, you must be two things: grateful and fulfilled. Being grateful is easy; take a moment to stop and look at everything in your life, say thank you with complete sincerity. This is why poor people are happy, they are grateful for what little they have. Being fulfilled actually takes effort; contribute to something greater than yourself, something selfless that increases equality with the people around you.
