  Privacy Finder is a privacy-enhanced search engine. Once you state your privacy preferences (low, medium, high, or custom), the search results are ordered based on how their computer-readable privacy policies comply with your preferences. A privacy meter with four green boxes indicates that the website complies with all your privacy preferences. Websites that do not comply with some or all of your preferences will have privacy meters with fewer than four green boxes. The number of green boxes that are missing are proportional to the number of preference conflicts between the website's privacy policy and your privacy preferences. The absence of the privacy meter means that a valid computer-readable privacy policy, known as a P3P policy, could not be located.

 Clonezilla, based on DRBL, Partition Image, ntfsclone, and udpcast, allows you to do bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla server edition. Clonezilla live is suitable for single machine backup and restore. While Clonezilla server edition is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. At the NCHC's Classroom C, Clonezilla server edition was used to clone 41 computers simultaneously. It took only about 10 minutes to clone a 5.6 GBytes system image to all 41 computers via multicasting!
