Never mind finding Roman roads (cool though that is), 1-meter accuracy laser scans of the entire country available for free has so many possibilities! Democratizing research, helping farmers, spotting environmental sinners, aiding education - this is a great project!

#Security weirdness of the day: I followed a link to #Instagram, and it told me they'd noticed an unusual login. Now I hardly ever log in to Instagram, so I imagine any login would be tagged as unusual.

I got a mail afterwards, but seriously, that's some weird shit.

If only the sun flares in my photos were this impressive.

If only the sun flares in my photos were this impressive. Originally shared by Astronomy Picture of the Day (APoD) A Solar Filament Erupts Image Credit: NASA 's GSFC, SDO AIA Team https://apod.nasa.gov/apod/ap180916.html What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun's ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth's magnetosphere, causing visible aurorae. Loops of plasma surrounding an active region can be seen above the erupting filament in the featured ultraviolet image. Although the Sun is now in a relatively inactive state ...
