Is porting something like a tracker to the Raspberry Pi when using its
onboard linux different than porting it to any other linux-based
system? Here I'm assuming you haven't developed your own kernel with
usb audio support.

I see a lot of people go and say they did this or that "on a raspberry
pi" but they're not using any special features it provides over any
other pc; it's kind of stupid, because if you look at all these

Raspberry Pi as a Spotify server with MPD control
Using OpenCV with the Raspberry Pi
Building a touchscreen XBMC setup with the Raspberry Pi
Multibooting the Raspberry Pi
Playing with the Minecraft API and a Raspberry Pi

...and make them say what really is going on...

PC as a Spotify server with MPD control
Using OpenCV with a PC
Building a touchscreen XBMC setup with a PC
Multibooting a PC
Playing with the Minecraft API and a PC

...then it's easy to see how ridiculous hanging everything onto the
Raspberry Pi has become.

Those were from the front page of the search for "raspberry" on
hackaday. What multibooting, spotify, and xbmc have to do with
hackaday I don't know. It's all kind of sad.
