It says the the intent was to make it similar to https://xkcd.com/195/ https://xkcd.com/195/ , i.e. with a space filling curve that preserves grouping, but actual implementation doesn't seem to do that. For example, the upper left squares are:
0 1
2 3
As opposed to
0 1
3 2
Also, 127.0.0.1 is near the right center edge of the map, while 128.0.0.1 is next row down near the left center edge.
- usr1106 3y agoFor the visual patterns on the map that does not make a major difference. * Obviously for all of the same color it makes no difference * For all 4 of different colors the pattern still does not change, it's just randomly colored * In case of 2 colors it's highly likely that the first half will have one color and the second one another. Nothing changes. * In the less likely case the 3 have one color and the remaining one is different the resulting pattern is a triangle. So the direction of the diagonal will flip. But I don't think the overall impression will change. In higher level squares replace "color" by "pattern", still no significant changes in appearance. Of course the two lower squares always swap their location.
- omoikane 3y agoMaybe the image would look just as random if a space filling curve were used, but I was hoping it would resemble the XKCD image somewhat. I have tried to rearrange the pixels to see if there is any resemblance, here: https://gist.github.com/uguu-org/5dadec83394d9ba5ea88e0f6e25ced64 https://gist.github.com/uguu-org/5dadec83394d9ba5ea88e0f6e25...
