Clone/download it from GitHub and feel free to let me know if you have any problem.

Finally got PulseAudio’s equalizer working. It consumes 1-4% of my 2.30GHz i5 CPU (Clementine’s built-in equalizer consumes 4-7%, btw), and sounds really good :)

In Gentoo, all you need to do to get this working is to install pulseaudio with equalizer USE-flag enabled (may need to unmask the unstable ebuild) and append this line to /etc/pulse/default.pa or ~/.pulse/default.pa (you can change the sink name to your liking) :

load-module module-equalizer-sink sink_name=equalized

After that, quit all applications that use pulseadio and restart pulseaudio:

pulseaudio --kill && pulseaudio --start

Now you should be able to use the equalized sink name for your multimedia application. For example, in Clementine, go to Tools » Preferences » Playback and change the Output plugin to PulseAudio Sink and fill the Output device field with your equalized sink name (equalized in the above example).

While Clementine’s playing, adjust the equalizer levels by running qpaeq. All done! ;-)

See the screenshot above? KDE’s default taskbar is now more powerful than ever! Right clicking on a taskbar item now gives you the ability to start a new instance of that application, and add a launcher of that application to the taskbar when it’s not running.

I know, it’s pretty similar to what Windows 7 offers, except (IMO) it’s waay cooler. In Windows 7, if you pinned an application to the taskbar, it will only show an icon, without the application name/window title, no matter the state of the application is (running or not). In KDE, well, you guessed it, if the application is not currently running, an icon will be added to the taskbar, and it will disappear when it’s launched.

If you really want Windows 7′s taskbar in KDE, you can install this plugin :)

add_action( 'load-widgets.php', 'my_widgets_admin_actions' );
function my_widgets_admin_actions() {
  # Enqueue scripts
  wp_enqueue_script( 'my-widgets-admin-scripts', plugins_url('myscript.js', __FILE__), array('media', 'wp-ajax-response'), '0.1', true );

  # Add the finder dialog box
  add_action( 'admin_footer', 'find_posts_div', 99 );
}

Next, create myscript.js file inside the plugin directory and add these lines:

jQuery(document).ready(function($) {
  // Find posts
  var $findBox = $('#find-posts'),
      $found   = $('#find-posts-response'),
      $findBoxSubmit = $('#find-posts-submit');

  // Open
  $('input.kc-find-post').live('dblclick', function() {
    $findBox.data('kcTarget', $(this));
    findPosts.open();
  });

  // Insert
  $findBoxSubmit.click(function(e) {
    e.preventDefault();

    // Be nice!
    if ( !$findBox.data('kcTarget') )
      return;

    var $selected = $found.find('input:checked');
    if ( !$selected.length )
      return false;

    var $target = $findBox.data('kcTarget'),
        current = $target.val(),
        current = current === '' ? [] : current.split(','),
        newID   = $selected.val();

    if ( $.inArray(newID, current) < 0 ) {
      current.push(newID);
      $target.val( current.join(',') );
    }
  });

  // Double click on the radios
  $('input[name="found_post_id"]', $findBox).live('dblclick', function() {
    $findBoxSubmit.trigger('click');
  });

  // Close
  $( '#find-posts-close' ).click(function() {
    $findBox.removeData('kcTarget');
  });
});

A quick explanation:
When the user double-clicks the input.kc-find-post field, the finder dialog box will popup. Clicking the Select button will send the selected post's ID to the input field. This can also be done by double-clicking one of the radio inputs at the left side of each found posts.

Need a demo? Just install KC Essentials :)

Save this script as jump.js inside katepart directory in your KDE user directory, eg: $KDEHOME/share/apps/katepart/script (just create the sub-directories if they don't exist yet) and relaunch Kate. Now you can move the cursor to the next paragraph by pressing Alt+Up or the previous one by pressing Alt+Down. You can freely customize the shortcut from Settings » Configure Shortcuts.

Any improvements are welcome!

As a bonus, here's the scripting guide I printed from Google cache.

jQuery(document).ready(function($) {
  $('.widgets-sortables').ajaxSuccess(function() {
    // do your thing
  });
});

I consider this as a hack, not because we’re going to edit a core file (never ever do that, please!), but because we’re (ab)using a filter hook to display the thumbnail, which should normally be done through an action hook. Unfortunately, if we take a look at wp-admin/includes/class-wp-terms-list-table.php file, there’s only one action hook in there, which can’t help us. However, there’s a filter hook that can be useful for our situation: "{$taxonomy}_row_actions", normally used to customize the action links that show up when we hover over a term row.

Before we begin, We need to decide how we attach an image to a term. There are many plugins out there that can help us with this, but in this guide we’ll be using my own plugin, KC Settings. By the way, if the plugin of your choice doesn’t use termmeta table to store terms metadata, I strongly suggest you to look for another plugin :)

Let’s get started with creating a mu-plugin file, or editing a our theme’s function.php file (not recommended). We’ll be using the category taxonomy throughout this guide, but you can off course use other taxonomies.

First we’ll add an entry for KC Settings, (please refer to the sample files included in the plugin to learn about the setting array), or you can also use the Builder if you like.

function my_category_metadata( $groups ) {
  $groups[] = array(
    'category' => array(
      array(
        'id'        => 'category-meta',
        'title'     => 'Metadata',
        'fields'    => array(
          array(
            'id'    => 'icon',
            'title' => 'Icon',
            'type'  => 'file'
          )
        )
      )
    )
  );

  return $groups;
}
add_filter( 'kc_term_settings', 'my_category_metadata' );

Now we can attach an image when creating/editing a term:

Attach/set term icon

To get the data, we can use get_term_meta(). For example, assuming the category ID is 20:

print_r( get_metadata('term', 20, 'icon', true) );

…which outputs:

Array
(
  [selected] => Array
    (
      [0] => 38
    )
  [files] => Array
    (
      [0] => 38
    )
)

Next, we’ll display each term’s icon on the term list table:

function my_category_column_hack( $actions, $term ) {
  if ( $icon = get_metadata('term', $term->term_id, 'icon', true) ) {
    if ( isset($icon['selected'][0]) && $img = wp_get_attachment_image( $icon['selected'][0]) )
      echo '<a href="'.get_edit_post_link($icon['selected'][0]).'" class="term-icon">'.$img.'</a>';
  }

  return $actions;
}
add_filter( 'category_row_actions', 'my_category_column_hack', 10, 2 );

We’re basically done, and the term table should now display the icons of each term. However, we need to add some CSS to make it look a little bit sexier and to match the Media screen.

function my_admin_inline_styles() {
  $screen = get_current_screen();
  if ( $screen->base == 'edit-tags' ) { ?>
<style>.term-icon {float:left;width:40px;height:40px;overflow:hidden;margin-right:10px} .term-icon img {max-width:100%;height:auto}</style>
  <?php }
}
add_action( 'admin_print_styles', 'my_admin_inline_styles', 99 );

First, we need to make sure that the partition which the /var/www directory resides (usually /has ACL enabled. The /etc/fstab line should look like this:

# Partition  # Mount point   # Filesystem     # Options         # Dump/pass
/dev/sda5    /               ext4             noatime,acl       0 1

If acl isn’t there yet, add it, save the file, and remount the partition by running this command as root (or use sudo):

mount -o remount /

If you can’t remount the partition for whatever reason, just reboot :)

Now run this set of commands as root, and don’t forget to change kucrut to your own username:

# Set ownership
chown -R kucrut:apache /var/www

# Set permission
chmod -R g+ws /var/www

# Set default permission for newly created files/directories
setfacl -d -m g::rwx /var/www
setfacl -d -m o::rx /var/www

… and we’re done.

Try creating a new file and check its permission:

touch /var/www/xyz && ls -l /var/www/xyz
-rw-rw-r-- 1 kucrut apache 0 2012-01-08 /var/www/xyz
