    It has WiFi, BlueTooth, Camera, touchscreen, Keyboard, GPS, and compass. It also runs A version of Linux "Android" but you can use c for it. One wonders how long it would take to get a version Ubuntu or MeeGo running on it.
    Another option would be the HTC HD2 but they are still over $200 but already run Windows Phone 6.x, WP7, Ubuntu, Meego, and Android.
    As new devices get bought these will come down in price. I am giving my Sister in law my Evo 4g because I got a Galaxy Nexus. The Evo has an HDMI out so all you really need is a Bluetooth keyboard and software to make an little desktop.
    Of course the issues of working drivers will be with use for a while but even that may pass over time.

    Lots of your assumptions are wrong.
    If it is certified then the engine will also have to be certified so you can just not throw a car motor in. Also car engines are not rated like aircraft engines. An aircraft engine produces full power at every take off and climb out. Aircraft cruise 75% to 55% power not at the 10 to 15% that a car does.
    Also you have the problems of RPM most aircraft engines produce their peak power at much lower RPMs because you must keep the prop tips subsonic. A 3500 RPM engine is a high revving aircraft engine while 6000 plus is common for car engines. You can gear it down but aircraft gear boxes are not very simple because of the loads that a prop puts on them.
    Now lets do the math.
    600HP=477 KWatts per hour
    The Tesla roadsters battery pack stores only 53kWatt Hours and has a mass of 445kg
    So using the same tech as the tesla figuring an average cruse of 75% power the battery pack alone will weigh 6000kg.
    A Cessna 182 has a groos weight of only 14kg
    BTW you cruse in most aircraft at 75% to 55% power not at around %10 but let's just for argument say that the plane can cruise at only 20% power you still have a 1200kg battery pack. Then add in a back up power plant fuel for the back up power plant, the electric motor and...
    Yea no happening without a massive improvement in battery tech over what Tesla can do. And I am using a 100% efficient motor in these calculations.

  8. Re:bad idea on China Plans National, Unified CPU Architecture · · Score: 1

    Maybe and maybe not.
    Look at x86 for example. You can go pretty for down the size and power scale with the Atom and then go up to Super computers all with one ISA.
    Arm goes from very small cpus up to pretty large and their is no reason why the ARM ISA "with 64 bit extensions" couldn't scale up as large.
    MIPS goes very down to very small systems using MIPS16e extensions which are a lot like the ARM Thumb extensions and can support SIMD, and 64bit at the high end. MIPS sounds like a logical choice for them to standardize on.
    If anything X86 has shown that you can make a terrible brain dead ISA work very fast with enough effort and extensions.
    MIPS is probably a better ISA than x86 and with only one ISA then China can put all of it's resources into making it work faster, use less power, and be cheaper than if they spread their efforts over many ISAs.
    As to a common back door for spying? Well maybe but I think that would be more of a fringe benefit than anything for the Gov. I think they see this as a way to leap frog ahead in the CPU race and not depend on the US for tech like CPUs.

    Ahh no your are wrong.
    "Even in the early 1960s it was easily out-performed by RAF V-bombers which could cruise past at Mach 0.96 and 20,000 feet higher."
    From the wikipedia
    Performance
    Vulcan B.1
    Maximum speed: Mach 0.96 (607 mph (1,040 km/h)) at altitude
    Cruise speed: Mach 0.86 (567 miles per hour (912 km/h)) at 45,000 ft
    Range: 2,607 mi (4,171 km)
    Service ceiling: 55,000 ft (17,000 m)

    B-52H
    Maximum speed: 560 kt (650 mph, 1,047 km/h)
    Combat radius: 4,480 mi (3,890 nmi, 7,210 km)
    Ferry range: 10,145 mi (8,764 nmi, 16,232 km)
    Service ceiling: 50,000 ft (15,000 m)

    I have seen slightly different speeds given but they are always within about 20 knots.
    I have seen different service ceilings given but the lowest for the B-52H was 47000 ft and I have never seen the Vulcan listed at 67000 feet which would be impressive to say the least
    As too the Vulcan's short field performance and high field performance well if you only loaded a B-52 with enough fuel to match the Vulcan in range say about half it's max fuel load and then only loaded it with the 20,000 lbs of weapons that the Vulcan can carry instead of the full 70,000 lbs that a B-52 can carry then I would bet the B-52 might give the Vulcan a run for it's money in that category as well.
    The Vulcan was a good medium bomber but the B-52 is a heavy bomber with much greater range and payload than the Vulcan.
    The Vulcan was closer match to the B-47 in range and bomb load but with a much higher ceiling AKA 20,000 feet higher and a slightly higher speed, of course the B-47 had been in service five years before the Vulcan entered service.
    Of course if the UK had spent the money that it wasted on the Nimrod AEW £1 billion "should have bought the E2, or put the E2s radar on a Nimrod or just bought the E-3 like they finally did" and the Nimrod MR.4 £3.6 billion Should have bought the P-3 updates or the P-8 now billons for nothing" on putting modern engines and avionics on the Vulcan it would still be a useful aircraft. Oh and let's not mention he money they are flushing down the WC on the A400M...

Sure some of it dies but the real issue is that people are unwilling to "fix" it. When most peoples 4 year old notebook gets to slow instead of wiping it themselves or even running Spybot they have to pick between paying the "Geek squad" $200 to do it or buying a brand new machine for $400.

    You know I am a republican and so was my mother and father. Thing is that even a conservative fellow like myself can see the benefit looking back at history that things like this gave the US. The problem is that back in the day people thought hey corporations where getting the fruits of government research for free so why not let them pay for the research. Well the problem is that the system we have now is that government still often pays for the research but now instead of results being in the public domain so any company no matter how big or small can use them some mega corp ends up with rights.
    Imagine how bad the US might have done in WWII if Grumman couldn't have used the NACA cowling on the Wildcat, Hellcat, and Avenger because Boeing had the rights to it. Or if North American couldn't use the NACA low drag airfoil that gave it such high speed and long range because Curtiss had the rights to it? Sorry but I feel you are just repeating the party line without thinking about it. Now a government body sell the the tech instead of just releasing it to any company in the nation for use is interesting. I thing that it being available to everyone free is a better solution but I am not an Australian so what I thing doesn't really matter in this case.
