I ran across this today, a short intro to running a django based website on the raspberry pi. To me this is really cool, as I think all of us can learn a great deal from working on limited hardware. It is challenging to make things work well there, and we really start to appreciate the cost of the things that we take for granted when working on larger systems. While obviously it isn't critical that we optimize all of our code to run on things like this, or even to be the most optimal as sometimes the real cost is developer time not execution time. However, being aware allows us ad developers to make that choice with more full knowledge, instead of making it by accident. Beyond that we are also just seeing computers everywhere, and our world is driven by them; so it is essential that we learn to make the best use of them no matter what their scale.
