A while ago I asked for help with a research project. I still need help, but now it's much easier to help! You can help without ever leaving the comfort of your web browser. And it will show you what it's doing.

I'm especially in need of measurements taken from outside Europe and North America.

(This does not work on iWidgets, or in desktop Safari, for reasons which elude me. It also doesn't work in old Internet Explorer for reasons that are known to me and difficult to fix. It should work on quite old versions of everything else. Bug reports, suggestions, patches, etc. will be gratefully accepted via the Github link at the bottom of the page.)

I am really quite impressed with how the "new G+" devotes even less space to the actual content of people's posts.  I didn't think that was possible.

I think this widget might be of interest to a number of people who follow me on here.  I'd hate to see it fall just short of the funding goal.

Call for Volunteers

For the past few months I’ve been working on a research study of 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.

In order to test some of these algorithms thoroughly, I need volunteers who are willing to run my measurement software on their computers, and tell me where they are. I’m especially interested in data reported from computers that are not in Europe nor North America, but data from anywhere is useful. Currently, running the software takes a fair bit of technical skill—if you’re not comfortable with the Unix command line, please wait for the friendlier web-based version which is in development.

If you’re interested, please go to https://research.owlfolio.org/active-geo/ for further instructions.

(For legal reasons, you must be at least 18 years old to volunteer.)

(Reproduction and dissemination of this call for volunteers is encouraged.)

For my current research project I need a modest-sized list (200-500 entries would be enough) of IP addresses which are pingable, distributed as broadly as possible over the entire world, and—this is the critical bit—they need to come with reliable information about their physical location, to ~100km accuracy. 10km would be better. (MaxMind and similar geolocation databases are not reliable enough for this.) Public datasets are preferred, but I'm prepared to sign NDAs if I have to. I'm not having any luck finding this; I'm not even having any luck figuring out where to start looking.  Anyone got some suggestions?

There's a recent Internet-Draft arguing that Postel's Maxim (Be liberal in what you accept, conservative in what you send) is fatally flawed from a langsec perspective, and I wrote a commentary on it: https://readings.owlfolio.org/2015/postel-was-wrong/  I'm looking for reactions to my test cases, and additional such cases.
