I don't see the <script> var ajaxurl </script> in my source code? Does this work with Wordpress 4.4? 

function wptreehouse_badges_refresh_profile() {
    $options = get_option( 'wptreehouse_badges' );
    $last_updated = $options['last_updated'];

    $current_time = time();

    $update_diff = $current_time - $last_update;
    if( $update_diff >= 30 ){
        $wptreehouse_username = $options['wptreehouse_username'];
        $options['wptreehouse_profile'] = wptreehouse_badges_get_profile( $wptreehouse_username );
        $options['last_updated'] = time();

        update_option( 'wptreehouse_badges', $options );
    }
    die();
}
add_action( 'wp_ajax_wptreehouse_badges_refresh_profile', 'wptreehouse_badges_refresh_profile' );

function wptreehouse_badges_enable_frontend_ajax(){
    //instruction to wordpress that when an ajax command is submitted - pass it through admin and down to the function
?>
    <script>
        var ajaxurl = '<?php echo admin_url('admin-ajax.php'); ?>';
    </script>
<?php
}
add_action( 'wp-head', 'wptreehouse_badges_enable_frontend_ajax' );

jQuery(document).ready(function($){

    $('.wptreehouse-badge').hover(function() {
        $(this).find('.wptreehouse-badge-info').stop(true, true).fadeIn(200);
    }, function() {
        $(this).find('.wptreehouse-badge-info').stop(true, true).fadeOut(200);
    });

    $.post(ajaxurl, {
        action: 'wptreehouse_badges_refresh_profile'
    }, function( response ) {
        console.log( 'AJAX complete' );
    });

});

Fixed needed to use 'wp_head' hyphen to underscore and break out the $url

function wptreehouse_badges_enable_frontend_ajax(){
    //instruction to wordpress that when an ajax command is submitted - pass it through admin and down to the function
    $url =  admin_url('admin-ajax.php');
?>
    <script>
        var ajaxurl = '<?php echo $url; ?>';
    </script>
<?php
}
add_action( 'wp_head', 'wptreehouse_badges_enable_frontend_ajax' );
