  1. Re: Undefined on Autonomous Car Ethics: If a Crash Is Unavoidable, What Does It Hit? · · Score: 3, Insightful

    That is not possible. I can see it in the court case. You had tge capacity to choose, yet you chose not to choose and my daughter is dead.

    But, the simple reality it, that will happen anyway, no matter what decision is made. ("You chose to minimize the probability of X, and now my daughter is dead.")

    I don't, by the way, buy the "Programmers have all the time in the world to get it right" bit. Programmers will not be able to anticipate everything, and their software will not always be able to calculate everything in the few milliseconds or so you might have to make such decisions.

  2. Re:Eddington Limit on Is There a Limit To a Laser's Energy? · · Score: 1

    The first part is irrelevant, as he asked the limit for "a cavity" (i.e., inside a specific sized object), and not on the target, but the second is not. You can, in fact, make your laser from a bomb and evade such limits. This was basically Edward Tellers idea for gamma ray lasers for anti-missile defense.

  4. Eddington Limit on Is There a Limit To a Laser's Energy? · · Score: 2

    As a certain energy density, the radiation pressure from the photons will be stronger than the tensile strength of the optical cavity, and the laser will blow apart. In astronomy, a similar limit is called the Eddington limit, so this is really the Eddington limit for a laser.

    The radiation pressure is (ignoring all factors of 2 or cos(incidence)) E / c. A tensile limit, T, of 500 mega pascals (reasonable for steel) thus would imply an energy intensity of c T, or 1.5 x 10^17 Watts/m^2. If the total cavity had an area of 1 m^2, then that's ~ 10^17 Watts.

    Note that it is common in pulsed lasers to have a lot of energy in a very short pulse (so the actual power during the pulse is very high). If your pulses were a microsecond in length, then the Eddington limit per pulse would be about 10^11 Joules, equivalent to 24 tons of TNT.

  5. Disasters on Drone Camera Tornado Coverage Raises Press Freedom Questions · · Score: 1

    Many rules are ignored / not enforced in disaster areas. This can go both ways - for example, your freedom of movement may be blocked by police enforcing evacuations, but the people looking for survivors generally don't worry much about one way streets or the laws of trespass. (And, yes, this certainly includes commercial activities, such as insurance adjusters.)

    My guess is that the FAA will ignore this, as long as it doesn't cause problems or get egregious.

  6. The nationality of the company on American Judge Claims Jurisdiction Over Data Stored In Other Countries · · Score: 0

    With apologies to various political hacks in the judiciary, corporations are not people, and this is one of many examples why, If I had a house in Ireland, and the US wanted something in it, they couldn't do much about it legally without going through the proper legal channels (e.g., applying to an Irish judge), especially if I was also residing in Ireland. Companies reside in the countries they do business in, which means they are located anywhere and everywhere, and subject to the laws of all of those countries, especially the nation that they are incorporated in.

    So, this is not surprising at all. I bet, too, that if Microsoft had some paper documentation relevant to this case , and those papers were in Ireland, the judge could order Microsoft to turn that over too.

  7. Re:Only $2 billion? What's stopping them? on Expert Warns: Civilian World Not Ready For Massive EMP-Caused Blackout · · Score: 2

    "Politics" in this case means that they haven't convinced the government that this money needs to be spent on them. Given that in these cases the government tends to have a bias towards spending money, I would regard that as telling.

  8. If people start exploding megaton class warheads 200 km above our soil, I would say that we have other things to worry about.

    Or, to put it another way, that $ 2 billion is being spent, and it's being spent several times over, just not here.

    When did Slashdot become infested with NSA apologists?

    Putin does this show annually. I am sure that the callers are vetted, but the questions tend to be wide-ranging, and don't really seem scripted to me. (I liked the one about buying Alaska back.) After all, it's a 4 hour show.

    Now, as for Snowden, I see this as positive. State security is not talked about that much in Russia, and he brought it up. While Putin said pretty much what Obama might have said in 2010 (in other words, it's fair to doubt whether he was being truthful), it gets it out in the open, and all in all I think that is a good thing.

    No. In that theory, the satellites interior to Iapetus, i.e., Mimas, Enceladas,Tethys, Dione, Rhea and (maybe) Titan would all have similar equatorial ridges, which they do not.
