  1. Post of FaceBook, interesting approach. on Netflix CEO Accuses Comcast of Not Practicing Net Neutrality · · Score: 1

    Trying to get what he wants through shaming Comcast, as apposed to the lengthy regulatory path. We shall see if this works. If Comcast is smart, and they are, they would let Netflix have its way on this. On the other-hand, If Comcast is tough, and they VERY much are, they will put Netflix into a long death struggle over this.

  2. How to fix hunger in Africa? on Ask Slashdot: How To Feed Africa? · · Score: 1

    I know this is politically sensitive. I am NOT trying to be a troll. I just want to be practical.

    The solution is: Birth Control.
    More practically, the solution is alleviating the need to have a large family.

    Look at the countries that are on the top of this list:

    This is REALLY simple folks. You want to have a MASSIVE famine? Step 1 is have a lot of babies.

  3. Really, Moral High Ground. on Richard Clarke: All Major U.S. Firms Hacked By China · · Score: 1

    Really?!?

    Did we just see a spy try to claim some kind of moral high ground by defining what he would and would not collect? Spying is Spying. It is an immoral act that if used to protect me/us from getting killed by an enemy obtains 'acceptability' through an 'ends justifies the means' argument.

  4. peak oil doesn't matter. on Hoover Dams For Lilliput: Does Small Hydroelectric Power Have a Future? · · Score: 1

    As an 80%+ correct statement.

    Oil makes transportation.

    Coal with some Hyrdo and Nuclear makes Electricity.

    Natural Gas makes home heating.

    Until most cars a electric cars (>15yrs), Hydro can only replace Coal and Nuclear.

  5. Actually answering the question. on Ask Slashdot: How Would Room-Temp Superconductors Affect Us? · · Score: 1

    With room temp super conductors the reduced i^2-r heat is nice.

    But copper is pretty cheap. That room temp super conductor would have to have quite a low price tag on it to replace copper transmission lines. So I doubt electrical-$ losses would drive users to adopt it.

    There are situations where the i^2-r heat makes choices for you. Being liberated from those decisions, is most likely the place where you would see i^2-r loss elimination decisions. CPUs and other compact electronics comes to mind.

    But, that is just an incremental change. A few more Ghz on your processor at best.

    The thing that is REALLY novel about super-conductors is the Meisiner effect.

    http://en.wikipedia.org/wiki/Meissner_effect

    Imagine a floating table.
    Imagine a floating bed.
    Imagine a floating car lift at a service station. turn the heater on, it drops to the ground, drive the car onto it, pour cold water on it, and up the car goes.

  6. I'm an Engineer. on You're Driving All Wrong, Says NHTSA · · Score: 1

    I push the seat as far back as I can and still have full reach of the controls. I put on all the belts they give me. I pull them snug.

    I'm also a bad driver, I've been in several medium severity accidents, and I can tell you first hand, the more physically secure you are, the better. And having your legs straight-ish means they flop around less in an accident. When an accident occurs, your strength means NOTHING. You WILL flop around like a rag doll.

    Oh, and I'm a 9-3 guy, generally a 3-only guy. The hot gas from the air bags have burned me, but I've never directly contacted inflated airbags.

    Be careful out there, I might be driving down your road some day. :)

  7. Re:Solar Output on Historic Heat In North America Turns Winter To Summer · · Score: 1

    Solar Output of a star like ours increases by about 10% per GigaYear. It DOES change. very very VERY slowly.

  8. when to do it. on What To Do About an Asteroid That Has a 1 In 625 Chance of Hitting Us In 2040? · · Score: 1

    The time to change this thing's movement is 2023. The time to start planning the mission is 2018. You don't need anything all that complicated, an 55 gallon drum full of shiny aluminum paint ought to be enough to fix the problem. Either that, or black paint. It would take a lander and a super-low-velocity sprayer.

  9. Re:Seems I'm always contrary. Well here goes again on Physics Is (NP-)Hard · · Score: 1

    The reason why I brought up Fermat's Theorem, is that very well argued explanations of what we can't figure-out or do, supplied by very highly credentialed persons, has not been a barrier to actually solving problems. Fermat's is an example of something, that was generally felt to be unsolvable, for centuries, but then was later solved in a way that you could almost call kinda simple.

    Making 100s of important problems into what is kinda 1 problem, is the first step in solving 100s of problems all at once.

    Considering your argument, if I could turn the 100s of NP-hard problems into something that could be explained to a computer as one problem. I could run an algorithm against it, and from time to time, get marginally better results. Until, I just didn't care about the results being better. Once that is achieved, for me, the problem is solved. Once, most people just don't care about the slightly better results, it has been generally solved.

    can't be solved, phish posh.

    still being contrary, I suppose.

  10. Seems I'm always contrary. Well here goes again. on Physics Is (NP-)Hard · · Score: 1

    So the article said that NP problems are all part of one family of problems or just different forms of the same problem. It further says that because these problems are 'hard' they can't be solved by computers. I must say, my gut instinct is that turning this many problems, and problems of this level of importance into one problems is the first step in solving all of them at once. oh, and before you tell me about how we can't see how anyone would really solve the 'NP-hard', first tell me how your so much more clever than the people who told us we would probably never solve this. http://en.wikipedia.org/wiki/Fermat's_Last_Theorem

  13. Fairly standard and illegal. on French Court Calls Free Google Maps Unfair Competition · · Score: 1

    INAL, but;

    Giving away free content/service/etc to put competitors out of business and then charging once you have a monopoly is fairly common. And its not allowed. Its not allowed in the U.S. It is an illegal practice banned under the monopolies law; and it has been banned for like 135yrs.

    Proving someone has done this, in common law U.S. Well, that's another story entirely. Proving it in France? Well there system is a little different, they can concentrate on effects of acts more and spend less time divining intent. France, is the right place to bring this complaint.

  14. Re:22 light years on New Exoplanet Is Best Yet Candidate For Supporting Life · · Score: 1

    most near-light designs have the ship being powered from earth btw. I.e. the earth hits the ship with a laser and a mirror on the ship gets momentum from the laser. The issue isn't fuel, its focus and range.

  16. Look at the Budget. on What If the Apollo Program Never Happened? · · Score: 1

    No one has a plan for going to the moon. The first moon program was done at a fraction of the actual cost due to the national pride and the massive donation of talent by the populous. It would cost twice as much to go again,but the plans all call for spending 1/10 of what was spent before. No one has a plan for going to the moon.

  19. I'm a nuclear engineer. on Bill Gates To Help China Build Traveling Wave Nuclear Reactor · · Score: 2

    ALL nuclear reactors DO have a proliferation risk in them. The main driver of the proliferation risk is they create and spread knowledge about how to safely and effectively work with highly radioactive materials. Some designs are worse than others in that the materials and of processing equipment can be directly re-purposed for weapons. With that said, the main reasons nuclear is dead in the US is, #1 Given its history, who is dumb enough to trust a multi-billion dollar investment to the regulatory whims of the NRC? Answer: No one with a billion dollars. #2, There are too many people who earn a living scaring people about nuclear power. Ralph Nader essentially retired on it. NIMBY is just a tactic they use.

    I hope solar and wind eventually pay-off because Hydro and Nuke are dead in the U.S.

  20. Maybe on Will NASA Ever Recover Apollo 13's Plutonium From the Ocean · · Score: 5, Informative

    I'm a nuclear engineer.

    These things are not cheap. We have recovered one from the ocean floor before to fly it on a later mission. (albeit, the relative shallows of the florida coast.) If its possible to build a remote sub that could find it, I would bet the cost of recovery would be less than the cost of manufacture. (radar, sonar? how many right angles are on that thing? HOW would you find it?)

    Its not dangerous. PU-238 cannot be used to make weapons.
