I once did the back-of-napkin calculations to make a scale-independent metric. Astronomers know that if you hold your fist at arm's length, your fist occludes roughly ten arc degrees in whatever direction you measure across your fist. My search found that someone's 20/20 eyes can generally resolve details to about 1 arc minute (didn't read Wikipedia's rationale). If that much screen area contains one megapixel or more, then the screen is well within the definition of a "Retina" display (at the given viewing range).

But kids CAN play with things like this:

Please see Schneier's paper on the "compelled certificate creation attack." Rather than asking a CA for the keys from Alice to Bob, they could compel a CA to vouch for an Alice to Eve, Eve to Bob connection as if it were Alice to Bob directly.

Aren't these units similar to the ASUS Transformer Infinity, which sells just fine at $400 or more?

I guess that's why you won't see them with an Android load and a discount. MS has probably contracted with ASUS not to do that.

No.

Sure, but who's going to pay for that? It's way cheaper to just print whatever's trending on Twitter. The public has clearly indicated that they don't really care.

If spacial ability in children is a predictor of their scientific creativity later in life, then if we could improve children's spacial abilities, this might produce more creative adults. The next step is to look for ways to do that, and then see if it worked.

Yes they do, so no, linking to a Tumblr page would not get the Tumblr page indexed.

And you can tell the difference between a Search-and-Rescue IR Camera drone from a Track-the-Perp IR Camera drone, from the ground? Or even a Take-Neato-Aerial-Photos prosumer level hobby drone?

are there really people into stalking slashdot accounts?

we've been getting these once-in-a-lifetime storms every ten years or so nowadays

My roommate and I did this in our apartment complex during college, running 10base2 coax to friends in another building in the same complex. It worked great for six months, until management found it and threatened eviction.

if any other cyclists come to blows with me, i will go home with a black eye, and still alive, rather than in a body bag, like Seth Vidal

if the desire to preserve my life is selfish in the matter of road rules that as far as i understand make no sense whatsoever, then i shall be selfish, and i shall insist other cyclists conform to what i am advising, rather than the other way around, out of their own selfish sense of preservation as well

and then the laws, and bad advice like yours, should change

as for your desire to clothesline people you have a problem with, that has a way of taking care of itself, as no matter how bad ass you think you are, there's always someone out there with an even worse attitude, and you type of guys always seem to have a knack for meeting each other, someone with an worse response than even you can muster, and you probably won't be getting back up. so you're a self-solving problem, friend
