one of the articles linked in the post does mention asteroids, and in truth, if an asteroid on a collision course or near miss was to intersect the radar signal, you would get several milliseconds, perhaps even a second, of pucker time before the event was over.

If we're on the Moon, it would be nice to be as self-supporting as possible, it would be nice to have a rail-gun to get off the surface of the moon with no fuel, just energy.
This can be manufactured on the moon. Producing solar cells of any efficiency from lunar materials should be the top priority.

As for living on the dark side, microwave beams up to lunar-orbiting satellites and back down to ground stations should be another priority.

The less we have to contract for from terrestrial corporations, and the more that can be produced on the moon, the bigger the techno payback we get.

Nuke power on the moon is so 20th century. Grow food using all-lunar technology. Generate air, etc., from moon tech. Then if/when we blow ourselves up the lunar colony won't need to worry about spare parts or resupply. Third priority, get to be able to fab robots from lunar materials. Chip fab should have some advantages in a vacuum environment, lots of other technologies needed or replacements for those technologies needed.

Did you see the little squiggly mark, also known as a question mark? Cool your jets.

Study was run by a guy at Duke University in tobacco country. They have a vested interest in keeping pot illegal? Something to consider if you have any free brain cells. Not defending pot smoking, just sayin cigarettes are as bad or worse.

The terrain looks suspiciously like the surface of Mars. Don't be a sucker. This could not work in Earth gravity.

Well, I suppose those types of alternative theories might also fall within the law, but I was limiting myself to theories of the origin of life, i. e., other religions, druids, the book of genesis as interpreted by r. crumb, stuff like that. Also maybe even get kids to think critically by looking at some less wellformed theories and tearing into them.
'spooky action at a distance' comes to mind. stuff nobody knows, like whether or not giraffes and chimps can swim.

Yep it's a challenge to live down here amongst the hillbillies. Tennessee's law actually doesn't mandate teaching creationism, it just prevents a teacher from getting into trouble for teaching alternative theories. As a substitute teacher (between software engineer gigs) I'm amassing age-appropriate clips from as many different religions and prehistoric traditions as I can find, so when the opportunity [resents itself, I'll be ready.

It's terrible to see the country slide backward down the ladder of technological pre-eminence due to these wackos. Decades of badmouthing government are going to take a toll on us pretty soon.

Note also that science shouldn't be taught as set in stone, either. There's a lot we don't know and kids enjoy comparing what was known to be true in my teenage years with what we know now.

Not believing in evolution after you've seen DNA is like sticking to chopsticks after you've seen the fork, no offense intended.

Too broke to purchase the original article but the free article says they deal with 'nodes in a plane' and the African example uses waterways so they are essentially using a tree there. These are npot the most complex data structures imaginable.

Also the means of defeating their algorithm is easy to figure out. Just make it look like the virus came from a well-connected user. These are likely pwned already, anyhow.
