Listen Digitally Imported Radio from CLI (without premium!)
This commands does just two things: fakes user agent (the one was taken from recent Android app) and sends the (possibly) listener ID (it can be any - I put "1" here because it works like a charm - after the name of stream ?1 as you can see). Look for the list of stations here: http://pub7.di.fm Or here: https://goo.gl/pdhhpQ Best regards, sxiii :)

Get information on your graphics card on linux (such as graphics memory size)
probably only works if you have one graphics card. used this: http://www.cyberciti.biz/faq/howto-find-linux-vga-video-card-ram/ as reference can be expanded, for example: $ lspci -v -s `lspci | awk '/VGA/{print $1}'` | sed -n '/Memory.*, prefetchable/s/.*\[size=\([^]]\+\)\]/\1/p' will just get the amount of prefetchable memory compare to: $ lshw -C display which does not give the size (it does give byte ranges and you could calculate the size from that, but that's a pain) Also uses a command which is not standard on linux; wheras lspci is a core utility provided by most systems
