       | What's that bright red spot roughly in the triangle between
       | Madison, Milwaukee, Chicago?
       | 
       | And another one below Osnabruck, Germany in Georgsmarienhutte?
       | 
       | What could cause this? Hardware error? Miscalibration?
       | 
       | Hrrm. Closed the tab and reloaded. 'Triangle' (Eagle Springs)
       | back to normal, Georgsmarienhutte still RED, new one in Taipeh
       | RED. Strange. Maybe software error? Or are the naturally occuring
       | fluctuations that fast?
       | 
       | Hrrm. Letting it run for a while, refreshing itself. Taipeh back
       | to normal, Georgsmarienhutte still red. Additionally
       | Nebra(Unstrut), Germany red.
       | 
       | Don't know what to make of this. Seems 'wonky'?

         | which are not verified in any way. It is a good effort but I

       | 
       | Putting a sensor in a truly hot spot, like a beach with thorium-
       | enriched black sand would completely swamp the scale.

       | The numbers I see nearest me match what I get on all my non-Alpha

       | counters always read more than double that. What types of sensors
       | are being used? Is this from the same feed that windy.com uses?

           | Odd, works for me. Maybe problems from the HN hug?

           | It probably doesn't have the information anyone wants though,
           | as it's the tutorial to activate your device GC Electronics
           | device to report to the site.

       | WHY? Afaict the only thing that one finger drag is bound to, is
       | an obnoxious message to use two fingers to do that.
