Adblocks don't fully block facebook ads. To block unecessary facebook clutter, I suggest FB purity. It enables to customize facebook and remove facebook ads.


There also quite some tools to test a particular website's accessibility. W3C provides respectively the following list and some explanations . Sorry if a bit off-topic :)

A way of avoiding this thing is installing a widget, like AdBlock, that blocks all the pop up adds that appear in your screen


The best way to customize a WordPress theme, is to create a child theme. To do this, you need to create a directory in the themes folder, add a style.css and set the the ‘Template’ parameter in its header to the name of the parent theme:

Theme Name: Some Child Theme
Template: some-parent-theme

Then you need to create a functions.php file and make sure to enqueue the parents css:

add_action( 'wp_enqueue_scripts', 'mytheme_enqueue_styles' );
function mytheme_enqueue_styles() {
   wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );

After that, you can copy any template file from the parent theme to your child themes directory and change whatever you need. These files won’t be overwritten when the parent theme receives an update.


First, the Site Address and the WordPress address need to be updated. Go to Settings->General in the WordPress administration area and change the value of these two settings to the new URL. New contents are now created with HTTPS.

Unfortunately, changing the site address does not update URLs in existing contents, so a SQL-Statement to replace the old URLs with new one is required (replace with the URL of the site to move):

UPDATE wp_posts SET post_content = REPLACE(post_content, '', 'https://

Thomson Reuter provides OpenCalais as a Web service to index texts ( into several categories. And there exist a module for Drupal integrating the OpenCalais functionality into Drupal Websites ( If this module is enabled we have possibility to set certain characteristics in /admin/config/content/opencalais.
First we have to register at Thomson Reuter to get an access key that has to inserted in the settings dialog.
Then we can goto certain content nodes to decide whether they shall be analyzed by the indexing service. Different categories can be used. Social tags seems to be the most promising category. I have enabled the service for challenges and solutions.


Mapping taxonomy terms from Drupal 5 to Drupal 7

In Drupal 7 tagging terms are stored as fields of the entity. In previous Drupal versions tags are assigned to nodes stored in a table taxonomy_index(nid, tid, created). In D7 we have some table as for example field_data_field_taggings were each term refrerence is stored as a row. If more then one term is assigned to a content node (e.g. in the answers module), the value in the column delta incremented to have a unique key. To generate this table we need an sql statement that increments this delta if more than one term exist for the node.
