  1. Re:Text columns that are too wide on Ask Slashdot: Why Do Mobile Versions of Websites Suck? · · Score: 1

    Looks like your browser is broken. Ok, all of them are, but place blame the right party.

    Also, why do you maximize your windows if you don't like the result?

    I'd disagree. Media queries are exactly the tool created for that use, and there is no immediate reason for not using them (if you have a deeper reason, I'd say that's a bug, please report it).

    Then for the example you used... All browsers (except maybe for IE) improve with time, and do that fast. If you fall into the schema of detecting the browser instead of testing for the capability, your site will become outdated.

    Gaphene not only does not seem to have any advantage, it's high resistance is a big disadvantage. Sounds super highly fishy.

    Err, what?! Graphene is an extremely good conductor, not a bad one.

  4. Re:everything you can't disprove is true on Simulations Back Up Theory That Universe Is a Hologram · · Score: 1

    After all we have no particular reason to believe the more concise theories are more "true", only more convenient/useful.

    Science is conveniently moving from a "let's find the Truth" to "let's get a usefull result" for a while now. You'll still not see most scientists explicitly agree that they are not looking for Truth anymore, but almost no one in interested in dealing with all the problems that come once you try to look for it.

    What? I take at least three tries to get an USB plug orientation right - and that after looking what's right beforehand, if not, expect at least five.

  7. Re:disparate on Over 20% of Online Black Friday Sales Came From Mobile Devices · · Score: 1

    Both of these have the same cause: you can get a low-end Android device, but not a low-end iDevice.

    Yet, there are more high-end Android devices out there than "single sized" iDevices. If they buy just as much, Android should get the biggest share.

    SOME correlation does not require exraordinary evidence. In fact, I quite expect it. That correlation reported here does require extraordinary evidence.

  8. Re:disparate on Over 20% of Online Black Friday Sales Came From Mobile Devices · · Score: 1

    If you're trying to advertise and encourage people to buy stuff, it makes sense to know who's going to buy things and how they're willing to buy them.

    Is that because you'll want to optimize your sales to those other people that aren't converting?

    Because that's the only action that makes any sense. The hypotesis that people's preference of phone model has that huge correlation on willingness to buy anything requires extraordinary evidence, and people pushing for it with just this study can not be serious.

  9. Re:but what about cheap disk? on How the LHC Is Reviving Magnetic Tape · · Score: 1

    HDD and tape do not use electric charge. They use spin orientation, what is much more stable, and self sustaining. Flash do use charges, and optical disk, chemical reactions. Theoreticaly, spin orientation is the most stable of those options.

    By the way, where is the phase change memory IBM was promissing us 15 years ago? Moving atoms full nanometers from their original position... that would be stable.

  11. Re:To hire specific people on Ask Slashdot: Why Are Tech Job Requirements So Specific? · · Score: 1

    Well, let me call bulshit, not exactly over your points, but over the entire thread.

    The specialist you choosed to hire simply does not exist, because no other place use the same set of utilities that you use. When you post those requisites, you'll simply flter the liars and people that think they know everything. The benefit you get for hiring the generalist is that you got a person that can actualy do the work.

    The generalist that is now specialized at working in your company can't use his education for getting into a better job, because the trainning he did was specific for your place and does not apply anywhere else. No other place uses the exact same set of utilities that you use. That does not mean that he won't live for a better salary - he will, because once you hire him you'll refuse to correct his salary for inflation and seniority, assuring the result.

    And that's assuming the patents stand up long enough for the checks to get written, something I understand may not happen as the patents themselves are facing invalidation.

    Last news I have (from the time GrockLaw still existed), most of the patents were already invalidated - but the judge decided that this small fact shouldn't change the veredict.

    The GP was certainly talking about the distribution of the icons on a grid. NOBODY ever tried to distribute icons on a grid.

    Apple was even nice enough to restrict their patent into colored icons, letting the entire set of phones with black and white screens (that's because nobody tought about a color screen before Apple - NOBODY) copy their completely new idea.

    I thought they just explained laws to anyone who was curious, didn't make a whole lot of sense why they needed secrecy for that

    No, you are not seeing the big picture. GL more than once gathered (and published) evidence of wrongdoing of well connected people. The entire point of mass surveilance is punishing such kind of behaviour.

    Why not just use the natural gas in an existing internal combustion engine.

    That depends. Are you willing to put a turbine with constant rotational speed inside your car? The difference in efficiency between a small internal combustion engine and a big turbine is huge (but hydrogen as an intermediary makes no sense).

    Net efficiency: .6*.65*.75 = 29%

    As always happen with untested tech, there are some steps missing from this calculation. Transportation of gasoline is about 98% efficient, but for hydrogen that number will be lower. Refueling with gasoline has some 9s of efficiency, but with hydrogen you can get it either fast at near 90% efficiency, or fill your tank overnight. Gasoline losses are almost nil, but hydrogen leaks away from the tank when you are not using it.

    My opinion is that hydrogen is only fit for rockets. With a lot of breakthroughts, it may become a nice aviation fuel, but for anything less dependent on weight, it's completely unfit. By the way, in the limited space of a car, making a 50% efficient hydrogen fuel cell is an incredible feat, 15% is a way more realistic number.

    Yes, and that's a great idea for mobile computers (maybe it'll be the next big thing there some time). It's just not that usefull for surpercomputing... still usefull, but not revolutionary.

    The problem is that supercomputers are made with the best of mass produced chips. You are already discharging the processors that can't run at top speed, and you already designed their pipeline in a way where variation in instruction times won't reduce your throughput. This way, all that you can gain from asynchronous chips is the variation that you ignored at the above optimizations because it was too small.
