2. Better probe location display. Currently I host two probes, both 10cm one from each other, put into two different ASes. When I have put exactly the same geo data, the "display" mechanism put one of it onto the other one.
This is a tricky one.
Background information: we'd rather not publish the exact geo-coordinates the hosts put in, because of privacy concerns. So what we do now is that whenever we display probes on a map, we round the geo-coordinates to two digits. This introduces a "random" error of up to 1000 meters or so. (If you zoom in on Amsterdam, where we have enough probes, you'll see that all probes are aligned into a neat, sparse matrix; it's because of this.)
It seems to be relatively easy to round the geo-coordinates to two digits (as you do it right now) and then add some random number from 0.00000 to 0.00999 to it. Piotr -- gucio -> Piotr Strzyżewski E-mail: Piotr.Strzyzewski@polsl.pl
