Two Things and a Beer-Drinking Mouse

Doc's Proplugs -- for those (like me) who have equalization difficulties scuba diving. I tested mine at 5 feet and they seem to be better than no earplugs. The real trick will be going down to 33 feet. Well, probably 24 feet. We'll see.

Via Jeremy Crowson. A Minute of Arc is 1/60th of a degree. Because we just love having measurement systems which don't divide evenly by any number system. 1/60th of 360ths. Yeah. Gotta love that.
By coincidence a minute of arc is approximately one inch for every 100 yards.
There's also a metric unit called the MilRad.
When I was in the Terran Mobile Infantry we didn't use any sort of explosive projectile weapons at all: just rail guns and lasers. And because I'm such a wuss they mostly assigned me as android liaison officer.

I like this mouse so much I'm just gonna keep blogging him.
