A comment on Mapping the internet with Hilbert curves.

The 9MB PNG is unoptimized. By passing it through optipng and advdef I managed to losslessly squish it down to 7MB.

Also, I would be remiss if I did not point out that this:

cat ping.txt | pcregrep -o1 ': (\d+\.\d+\.\d+\.\d+)'

is a Useless Use Of Cat.[1]

It should be rewritten:

pcregrep -o1 ': (\d+\.\d+\.\d+\.\d+)' <ping.txt

It's pretty good when compared to uncompressed RGB of the same size, which would be 48M.
