Spreading the word (h/t to [personal profile] mindways) -- Fatal Encounters is a site doing research that everyone has talked about for decades but ever-so-conveniently not actually performed: how many people are being killed by police, under what circumstances, and how has that been changing over time? In an absence of data, talking heads fill the void with their own assumptions, and that needs to change. So they are building out an as-comprehensive-as-possible searchable database on the subject.

They're currently running a modest IndieGoGo campaign to fund operations for the next six months. It looks to be a good cause, and I've tossed a few dollars into the pot -- check it out...

Having not done the advance planning needed to procure a pair of the dorky-but-necessary goggles for directly looking at the eclipse, I did the quick-and-dirty version instead: creating a "pinhole camera" by taking two index cards, punching a hole through one with a needle, holding them a couple of inches apart, and adjusting the distance between them until I got reasonable focus.

Quite neat -- while not nearly as spectacular as being in totality no doubt would have been (both my parents and my boss flew to the Carolinas for it today), it provided a good firsthand illustration of the principles as the visible dot in my "camera" went from circle to crescent over about ten minutes or so.

The one negative observation: I am now nearsighted enough that actually observing this now requires taking off my glasses. (Even my bifocals aren't good enough to resolve that level of detail. But at least my eyes are Really Good at Up Close and Tiny nowadays.)
