In the last week in August (2012), the Raspberry Pi Foundation started selling MPEG2 codec licenses for the Pi. The -a flag allows you to view files beginning with . If we wish to consciously decouple software from hardware, an off-the-shelf solution like a Bluesound or a Sonos won’t do. To extract the contents of a file, use tar -xvzf *filename.tar.gz*, A pipe allows the output from one command to be used as the input for another command. You get to do 31 experiments out of the box, following the instructions given in the CD that comes with the kit. Install gparted on your Raspberry Pi. Pi 101.
