ELC2009: Visualizing memory usage with smem

One important thing to note is that no music player or web browser is open which makes the picture look quite different from that most users would see - with Firefox being the dominating application by an order of magnitude.

Not necessarily so... The pie chart diagram mentions that smem was run only for processes whose name begins with a 'k'. But, I agree that Firefox would undoubtedly be the biggest slice of pie if it were shown.
