Whitehouse.gov now powered by Drupal
"The online-savvy administration on Saturday switched to open-source code for http://www.whitehouse.gov meaning the programming language is written in public view, available for public use and able for people to edit.
"We now have a technology platform to get more and more voices on the site," White House new media director Macon Phillips told The Associated Press hours before the new site went live on Saturday. "This is state-of-the-art technology and the government is a participant in it.
Under the open-source model, thousands of people pick it apart simultaneously and increase security. It comes more cheaply than computer coding designed for a single client, such as the Executive Office of the President. It gives programmers around the world a chance to offer upgrades, additions or tweaks to existing programs that the White House could - or could not - include in daily updates.
Yet the system - known as Drupal - alone won't make it more secure on its own, cautioned Ari Schwartz of the Center for Democracy and Technology.
"The platform that they're moving to is just something to hang other things on," he said. "They need to keep up-to-date with the latest security patches."
