OFFTOPIC: friends from foocamp requests help from outside North America for researching censorship; script to run on *nix

Because most responses will be from North America, I thought it would be
particularly valuable if people on this list might be willing to help.

Details here <https://research.owlfolio.org/active-geo/>

From their website:

Active Geolocation Project

This website is part of a research study conducted by *Nicolas Christin*
and *Zachary Weinberg* at Carnegie Mellon University.

The purpose of our research is to test “active geolocation” algorithms.
These attempt to determine where in the world a computer is, by measuring
how long it takes network messages from that computer to reach other
computers in known locations. We test them by making measurements from
computers in known locations. We can then compare the position calculated
by each algorithm with the truth. We’re also comparing with the position
reported by commercial geolocation services (such as MaxMind
<https://www.maxmind.com/> and Geobytes <http://geobytes.com/>) for the
computer’s IP address.

https://research.owlfolio.org/active-geo/  Especially want people
outside Europe and North America."
