It has been a while since the portal for the White House (www.whitehouse.gov) has migrated their infrastructure to Drupal, a well known FLOSS CMS. Now, the site has announced, on April 21st, that it has made available, as free software, some new drupal modules developed in-house by them.
One of these interesting modules is "Node Embed", which eases the management of photos and videos within drupal.
