It has no particular name. I was toying around with the Princeton Cold Boot Attack (http://citp.princeton.edu/memory/). In particular I was interested in how much memory is erased when I would (on my system) enable the slow POST (which counts through all RAM three times). I downloaded the provided utitilities, dumped my system memory via PXE boot onto another system after resetting it hard in the middle of a running Linux session. I did sync, though. Praise all journaling filesystems. As a 2GB file is not really of much use for telling where something is and where isn't, I thought of that picture coloring. In a 1024x1024 picture a pixel is 2048 bytes with 2GB of RAM, so exactly half a page. This is sufficiently high resolution to detect what's in there. > I'm curious :) I haven't had much tiem to > optimize it yet - I'll try to when I get home from work. Thanks for your effort, I appreciate it... hope my work leads to some meaningful results. Currently it looks (*cough* if there aren't bugs in my picture code) as if my PC would reset the whole RAM anyways, although I do not have any ECC. Strange.
