I've been known to accidentally leave a stream of music running all night when I'm not there to listen to it anymore. That wastes bandwidth and energy.
Here's a quick tip to prevent from happening, by causing any music playing to be turned off at 7:00 pm each night.
On Ubuntu Linux, add these lines to
/etc/crontab. You can edit this file with
gksudo gedit /etc/crontab:
Note that "rhythmbox" is the name of the music players I use. Change as needed.
# stop streams from playing all night. 0 19 * * Mon-Fri killall --quiet rhythmbox
If you need to adjust the time, the first two columns of numbers are the minutes and hour columns.
