FOG Project: A free open source cloning program. It runs on Ubuntu or Fedora and stores copies of computers hard drives. It requires DHCP, but it can be the DHCP server or you can edit another DHCP server with scope options. It transfers the data over the network. This means that all your computers should be PXE (Pre-boot Executable) compliant. If your computers are unable to boot to the network card, then it is possible to use a free boot CD such as iPXE or gPXE. The idea is to install the operating system on the computer along with all of its required software. The computer then may be preserved in its prime condition. If the OS becomes corrupt or infected, it is easy to erase the hard drive and put the FOG image back. This relies on the fact that no critical data is stored on the computer and is in danger of being erased. Fog works best in client-server environment. It is available from www.fogproject.org

WordPress: WordPress is an open source tool used for creating websites. It was released in 2003 but has evolved to the point that it is a very good fit for all manner of websites. WordPress is available from WordPress.org. The company that supports WordPress also runs a free service where it is possible to use your own sub-domain at WordPress.com. They also offer a service of hosting a WordPress website at Automattic.com. The version available from the .Org site is meant to be hosted on your own server. It typically requires Apache, PHP, and MySQL to operate. However, WordPress has been made to operate on more that just that common platform.
