  1. Re:Phoney issue on EU To Allow 3G and 4G Connections On Planes · · Score: 1

    You pass from cell tower to cell tower so fast it confuses and stresses the system.

    According to TFA, this is a separate system that doesn't use your carrier's towers. To me it sounds no different than offering WiFi on the flight (which is relayed to the wider internet using a dedicated system such as satellite):

    To give passengers mobile Internet access, airlines need to equip planes with an improved mobile communication on-board aircraft (MCA) system that makes use of pre-existing spectrum bands for 3G and 4G, the Commission said. These systems are connected with the ground via a satellite connection and have a signal with limited power to ensure there is no interference with other communications, it added.

    So, I don't see the advantage over using in-flight WiFi, it's just a different way to talk to the same onboard transceiver. (Are there any 3G/4G phones without WiFi?)

    How about auto repair? I think it's a good place to start with mechanical skills because everybody owns a car, and knowing some basics will save you money even if you don't choose to do much yourself, let alone be employed in the field. It exposes you to mechanical, electrical, and hydraulic systems, and some actual motivation to fabricate or recondition parts in a subsequent shop class.

  5. Re:Then again, who cares? on How Blockbuster Could Have Owned Netflix · · Score: 1

    It seems to me that most mergers are for the benefit of top management. The investors have stock in both companies so it hardly matters to them - they only benefit if the whole is really more than the sum of its parts. There's no direct way to measure this - even if the merged company is soon worth more than the two that were combined, maybe it's because they're now monopolizing the industry, so the extra profits come at a cost to other industries in which investors also have shares.

  6. Then again, who cares? on How Blockbuster Could Have Owned Netflix · · Score: 1
    The premise of this story is that Netflix could have been bought by Blockbuster, and that Blockbuster would then have operated Netflix pretty much as it is operating now. Under this assumption of more dynamic Blockbuster management, they would have been shutting down the retail stores about now anyways, since they are not profitable any more.

    In other words, the world would be just like it is now, but with a different brand name on a website. No more or less movies would be available to consumer, and there would be no more or less net jobs.

    I can't think of one meaningful thing it would have actually changed.

    What's wrong with 28-40 FPS on BF4 at 1920x1080? That's a brand-new game with high end graphics.

  8. I meant, each spinup/spindown is a thermal cycling. This causes the parts to expand and contract, which is hard on them.

    To mean anything, "cloud" must at least include redundancy of both the data and the network to access it.

    Anyways, it is far from ridiculous for RedHat to aspire to this. RedHat is used in many data centers and has contributed a very large number of software packages for clustering, management, and virtualization.

    Keeping your life savings in your back pocket is also a bad idea. Nothing about personal computing is really set up with the idea of computer files worth tens of thousands of dollars.

    Please go ahead and reply with "Just do X!" But I'm not buying it unless it's at least far safer than treating a stack of $100 bills the same way, because that is NOT how I protect my savings.

    The Intel Iris Pro 5200 is 28% faster than the Geforce GT 630 on the PassMark G3D benchmark. (I don't know how much the variants you linked differ in performance?)

  13. Or maybe significantly shorter. Spinup is what stresses the system, and each spinup/spindown is a cycling. A really tired old drive may work until you let it spin down, then not be able to start back up.

    Ewww, I hope they don't bring back quotas in my area. I never actually exceeded the 250GB one, but the kids are watching more streaming video at higher quality all the time...

  15. Re:Enjoy it while you can on Netflix, Youtube Surpass 50% Mark of Internet Traffic · · Score: 2
    As a long-time Comcast customer it seems to me things are going in the other direction - better! They had a 250GB cap for a while and then gave up on it. Years ago, youtube used to stall all the time and now rarely does. Then youtube was OK but then Netflix (then Prime) always paused to buffer at least a couple times during a show, whereas now it hardly ever does. I've been a VOIP user since I think 2004 (Vonage then Ooma) and, whereas it was initially fairly embarrassing to use, the spousal complaint rate has really gone down the last couple years.

    I don't think Comcast can put the cat back in the bag at this point. People just expect stuff to work. And Comcast no longer dwarfs the content providers (Google, Netflix, Amazon...) They won't lie down.

    Of course YMMV, I'm curious if others still have a lot of trouble streaming video?

    Actually I noticed the 5S release was different (for Apple) in that very respect - they trumpeted very little besides behind-the-scenes specs. 64 bit! New co-processors! Look at these benchmark graphs!

  22. Re:This is not a fair comparison on Nexus 5 With Android 4.4 and Snapdragon 800 Challenges Apple A7 In Benchmarks · · Score: 4, Insightful
    That's no different than claiming the A7 is pathetic for needing 64 bit registers to do what the SnapDragon does with 32. Which is to say, very silly.

    Now, if double cores and double the MHz give the Nexus 5 less battery life than the iPhone, then you have a leg to stand on.

  23. Actually reducing waste is the closest you can get to getting something for nothing. When you turn on a lightbulb, what percent of the photons emitted happen to bounce around and eventually fall through the lens on somebody's eye? Hardly any - it's a minuscule percent. Thus "solar"-powered wallpaper to re-absorb energy from lightbulbs sounds stupid but makes perfect sense, if it could be produced cheaply enough. Broadcast RF signals are similar.

    And by the way, if you want to make a display that uses hardly any power, make one that only emits energy into the eye (perhaps using eye tracking). It's like the difference between earbuds and loudspeakers, i.e. a factor of thousands. My mp3 player runs all day on a battery smaller than a AAA, whereas the 15" sub in my livingroom can make the lights dim.
