Signal scramblers. I know it's illegal in several countries, but it's used very effectively (and legally) in some theaters in Paris.
Of course, that would not prevent someone to take a picture/record a movie of you and then use some facial recognition algorithms at a later time, but it would still mitigate some of the abuse that "instant" facial recognition apps would bring to the table.

Comment Re:Space is no longer a war free zone thanks to Ch (Score 1) 87

The US has conducted a little experiment in 1962 called "starfish", in which they blew up a nuclear missile in space. It created temporary artificial radiation belts which knocked down a number of satellites.
The bottom line is that space has been a war zone long before China did their ASAT missile experiment.

You should not be too quick to dismiss our high vernier acuity. It is the main mechanism behind the aliasing effect. The difference is not so much in rounded objects than in slightly slanted ones. I still see plenty of aliasing on slow moving scenes on my 1080p 32" TV, and my eyes are very average. Look at the geometrical objects with high contrast... painted stripes on a track, edges of some buildings... And if you happen to play videogames, it's even more noticeable, as scenes are unnaturally geometrical, sharp, in focus and with a low motion blur.

Your comment is very interesting, because I think it reflects that for some matters, the USA are really unlike any other place. I've made a few times road trips in the US - and I found them really tedious and a chore. And it's not that I don't like to drive - but I can hardly see the pleasure of driving for several hours on a mostly straight road - I'd rather take a high-speed train if it's for watching the scenery. Yet, you're talking about your trip as an adventure, and I don't doubt at all that you really consider it to be a pleasant moment with your family. With that being said, I think it's easy to see why EV will have a hard time in the US market. But bear in mind that there are many other places in the world where they might be much more suited to the people expectations.

Well, I can only advise you to read more carefully the investigation report (which was made by the BEA, not the FAA).
The airspeed indicator gave wrong information for 61 seconds at most .The others indicators (such as pitch indicator) were functioning correctly, yet it was the inappropriate control inputs of the pilot flying that directly put the aircraft into a stall. The stall warning sounded continuously for more than 54 seconds, yet nobody in the cockpit voiced the possibility of a stall. The main problem was that the crew in the cockpit was deeply confused... probably overloaded with information they couldn't prioritize, and discarded (consciously or inconsciously) the warnings presented by the aircraft systems. Saying that they "followed the computer instructions" is a deeply flawed way of describing the situation.
