"I had only done a blog on Linux yesterday, and there is already some more news of obvious incompetence in the Linux world. The forums of Ubuntu, the most popular Linux distribution, have been hacked. Currently there is an announcement with the following message: Ubuntu Forums is down for maintenance" .     reference:http://scalibq.wordpress.com/2013/07/21/speak-of-the-devil-ubuntu-forums-hacked/#comment-4320
