  1. Full virtualization rights? on 'UpgradeSubscription.exe' File In Preview Build Hints At Windows 10 Subscriptions (zdnet.com) · · Score: 2

    I would be interested in Windows subscriptions if it included full virtualization rights. As it is now, licensing Widows for virtualization is a clusterfsck.

  2. So amatuerish on Hyperloop One Technology Tested Successfully In Nevada Desert · · Score: 2, Interesting

    I couldn't believe how crude their contraption is. Everything they did is 20+ years old. There are theme park rides a hell of a lot more advanced than that thing and they will brake automatically and carry passengers.

    Why aren't they concentrating on a 1/10 scale proof of concept that will be a hell of a lot cheaper to make and can advance the technology?

    Companies that want make money, make money.

    At the end of 2009:

    Nokia made $1.1B total with a 35% mobile phone market share
    Apple made $1.6B on just the iphone with a 2.5% mobile phone market share

    What's the better business to be in again?

  5. The best reason I've heard for why to stop Adobe.. on Adobe Stops Development For iPhone · · Score: 1

    from doing the Flash to iphone porting.

    Let's say that Adobe is wildly successfull and 10%+ of the available iphone apps are flash converts. ( I could easily see 50K flash ports )

    Then say Apple wants to change the way they do things in OS 5 or 6 which will break all those apps.

    Apple will be at the mercy of Adobe to update their software to work on the new OS or those apps won't work. ( Adobe seems to be on a 2 year release schedule )

    If all the programs are written in Objective C, all Apple needs to do is update the compiler ( which they control ) and all the apps can be ported to the new OS without issue.

    Google releases a new operating system. You will be able to upgrade your new HTC Desire.

    ( ) They day it's released
    ( ) A few days after it's released
    ( ) A few months after it's released
    ( ) Never. HTC Makes money by selling you a new phone with a new operating system. They don't really have any incentive to upgrade an old phone with the latest features.

    Apple releases a new operating system. You will be able to upgrade your old phone.

    ( X ) The day it's released. Every feature may now be available, but if the hardware can handle it. It'll work.

  8. Re:It won't work. on Murdoch Says, "We'll Charge For All Our Sites" · · Score: 1

    Just because there are a number of quality news sources now that are available for free. It doesn't mean this will always be the case.

    Print is currently subsidizing the online stuff. Revenues are constantly decreasing.

    There will come a point where the number of quality sites will be so infrequent that a quality site will be worth paying for.

    As soon as someone can come up with a workable micropayment system, everyone will jump on board.

    This looks like another opportunity for Steve Jobs....

  9. Re:Today's news = sad days for new iphone3g owners on Apple's WWDC Unveils iPhone 3.0, OpenCL, Laptop Updates, and More · · Score: 1

    you didn't pay $199 for the iphone... you paid $199 + 24*$69 = $1855 ( you now, the monthly fees )

    The new price is $99 + 24*$69 = $1755 or a 6.5% price drop. ( Assuming AT&T's pricing doesn't change )

  11. Re:Take advantage of aerodynamics on Fuel Efficiency and Slow Driving? · · Score: 1

    This is actually a myth.

    Drafting close is actually a benefit to both vehicles.
    The front vehicle creates a hole in the air for the back vehicle, and the back vehicle drags the air behind it that the front vehicle would normally be dragging.

    The back vehicle does see the greater benefit however.

  12. 6 Ft? on Practical Jetpack Available "Soon" · · Score: 1

    The highest the inventor has ever flown is 6ft and he ruined it demoing for the reporter by sucking in tree branches..doesn't instill confidence.

    With 600lb thrust and a 450lb vehicle and operator weight, the craft only has 3.2m/s2 of vertical acceleration.

    If you're 14.4m (50ft) off the ground and decending in excess of 9.6m/s (21mph) you're not going to decelerate to zero before hitting.

    Gas tanks don't explode. It takes 3 things to get something to burn. Oxygen, Heat, Fuel. To get something to explode, the fuel needs to be dispersed in the oxgen and there needs to be enough oxygen to support the explosion.

    There is hardly any oxygen in a gas tank.

    There's an episode of Mythbuster where they shoot tracer rounds (burning bullets) into a gas tank and can't get it to explode. Not enough oxygen, and the fuel isn't dispersed in the oxygen.

    Batteries are OK in that the rate of discharge is limited by the chemistry involved. It's takes a while to fully dischage. The battery might get so hot that it melts everything around it, but it doesn't explosively dischage.

    Capacitors on the other hand, have extremely high discharge rates and require no fuel, oxygen or heat to explode. Enough energy to power a vehicle for more than 100 miles would cause serious damage if the capacitor were to fail from an accident or manufacturing defect.

    Everyone may think putting capacitors in a car is a good thing, but you're essentially mounting bombs in the car.

  17. Ka Booooooom!!! on MIT's Nano Storage Could Replace Hybrid Batteries · · Score: 5, Informative

    "And by avoiding the chemical reaction that drives traditional batteries, there's no real danger of a capacitor suddenly overloading--or exploding like a laptop's lithium-ion battery pack."

    They won't explode like a lithium-ion battery pack, it will be a 100X worse.

    If anything pierces the dielectric, all the energy stored in the capacitor will discharge violently in milliseconds.
