The Linux operating system is a multi-user operating system that accepts multiple users to log on and use a single computer.To protect the computer (and other users ' privacy). Users are limited in what they can do.Most users agree to execute most of the programs on the computer and edit and save files stored in their own home folder. The general user does not agree to edit other users ' files and some system files.However, there is a special user on the Linux system called Superuser, which ofte

One advantage of the Raspberry pi is that it has a strong video decoding capability, and it's a good option to use it to play video. It will be used for the next two seasons as a home media hub, and the XMBC software and RASPBMC distributions make this possible.First, XMBC and RASPBMCXMBC (soon to be renamed Kodi) is a leader in open source Media center
