    Actually, if you combine Windows 7 (regularly patched at least once a month on "Patch Tuesdays") with Microsoft Security Essentials 2.0 (3.0 is coming later this year), Windows is actually a quite secure operating system. And more importantly, Windows 7 has the hardware driver and third-party software support that LInux wishes it could have, including using better free web browsers like Firefox 12.0 and Chrome 17.0.x versions.

  4. Re:And this is better than thorium because....? on Is It Time For the US Government To Back Fusion At NIF Over ITER? · · Score: 1

    The fact that we actually built a test reactor at Arco, ID and successfully tested it for five years non-stop proves that the concept behind the liquid fluoride thorium reactor (LFTR) actually works.

    I'd like to see someone scale up this technology to build a test 85 to 100 MW reactor to prove the concept once and for all, especially considering the potential benefits of this reactor type:

    1. It uses plentiful thorium-232 dissolved in molten sodium fluoride as fuel, a form very cheap to make compared to assembling uranium fuel rods.
    2. LFTR's don't need expensive pressurized reactor vessels.
    3. Shutting down an LFTR in an emergency is quickly draining the liquid fuel from the reactor--a lot cheaper to implement than the safety systems used in uranium reactors.
    4. You can use spent uranium fuel rods and even plutonium dissolved in molten fluoride salts as fuel, eliminating a major radioactive waste disposal problem.
    5. By using closed-loop Brayton turbines, we eliminate the need for expensive cooling towers or locating the reactor near a big source of cooling water such as a river, lake or next to the ocean.
    6. The amount of waste generated is very small compared to the waste generated by uranium reactors. More importantly, the waste's radioactive half-life is under 300 years, which means the waste can be dumped into any salt dome or disused salt mine for very cheap waste disposal.

    We should ask the people in Japan and South Korea the experience of using such systems, where NFC mobile payment systems are very widely used. Especially in Japan, where the mobile version "FeliCa" system (jointly developed by NTT DoCoMo and Sony) is universally used for such payments.

    I believe that the US-based ISIS system is based a lot on what was learned from Mobile FeliCa.

    We have a "chicken and egg" problem with FLAC--what large record company will release files in this format, and when will all the major portable music player makers (especially Apple, who controls the vast majority of the market through the iPod and iPhone) support it? Sure, you can convert FLAC to other formats, but the problem is that most computer users are not interested in installing a third-party program to do this conversion.

  7. Re:Apple has a "lossless AAC format" on Mastering Engineer Explains Types of Compression, Effects On Today's Music · · Score: 1

    It should be noted that Apple Lossless has been Open Sourced under the Apache license model, so it's no longer a true "proprietary" format.

    Despite what supporters of FLAC say, FLAC has not gotten "traction" for large-scale music sales because only a small number of portable music players support FLAC natively. Meanwhile, every iPod made since 2005, every iPhone and every iPad supports Apple Lossless natively; as such, once record companies start releasing tracks in Apple Lossless, there is already a huge potential market for such such music files.

  8. Re:Mix it on Multiword Passwords Secure Or Not? · · Score: 1

    In short, the best easily remembered security is to use at minimum 12 character password that is not understandable by any dictionary.

And the password generated is not anywhere close to recognized as an English, French, Spanish, German or Italian word. And I change the password every 60 days.

    In short, it's close to impossible to guess the password.

Indeed, they built it at Sumida-ku ward as part of major urban redevelopment project in that part of Tokyo, which was once known as a working-class part of that city.

  16. Re:Too expensive on Chevy Volt Meets High Resistance, GM Suspends Sales · · Score: 1

    A couple of things:

    1. I do agree that the Volt is TOO expensive a vehicle. A better solution are the more conventional hybrid drivetrains that Toyota and Ford developed, both of which offer very good fuel economy without totally silly prices. Indeed, a Toyota Prius Model III hatchback at around US$25,000 is actually a bit of a bargain, considering that conventional sedans that have the same interior space as the Prius cost almost as much as a Prius Model III!

    2. As for turbodiesel, the combination of higher NOx output and diesel particulates makes to quite expensive to make such engines meet EPA "Tier 2 Bin 5" emission standards. However, with the arrival of Euro6 emission certification, that might change, since Euro6 is very similiar to the EPA standard. Europe loves diesels, but they're doing it at the expense of higher air pollution from diesel exhaust.

  17. Re:First Off, Listen to Chris Martenson on US Wants Natural Gas As Major Auto Fuel Option · · Score: 1

    This is not the first time we had to switch energy sources FAST.

    Up until the 1840's, night lamps were fueled by whale oil--but we ran in to a big problem: we were running out of whales to kill even back then. A substitute was needed fast, and by the 1850's, that substitute was discovered: kerosene, which came from the crude oil extracted in Pennsylvania. Indeed, it was that success that made John D. Rockefeller one of the richest persons in history.

    Today, we realize that we need to begin the transition from petroleum to other energy sources. Promising research into batteries with much higher storage density could mean far longer-ranged electric cars by 2020, and there is considerable money invested into growing oil-laden algae on a huge scale to use as a base to make motor fuels. I actually predict that by 2025 the average family car will be an all-electric vehicle with a full-charge range of 700 to 800 km (435 to 497 miles) that will be physically smaller than today's cars (remember, engine compartments will be much smaller) but just as roomy.

  18. Re:Mass Transportation in America on The Specter of Gasoline At $5 a Gallon · · Score: 1

    The problem is that for mass transportation to work, it would require people to live in VERY high density cities to justify the cost of construction.

    For example, in Tokyo the population density of that city is high enough to justify Tokyo's very extensive subway and commuter rail network. And even that is barely enough, as we can see from the amazing amount of people going through the big train stations like Ueno, Shinjuku, Shibuya, and the main Tokyo station during commute hours.

  19. Re:Gas will only get more expensive on The Specter of Gasoline At $5 a Gallon · · Score: 1

    No, all it will do is just make Volkswagen Chairman Martin Winterkorn's prediction of a VW Golf-sized electric car with a surprisingly small-sized battery pack that can go 800 km (497 statute miles) on a single full charge happen possibly before 2020!

    And it's not as crazy as it sounds. Thanks to recent developments in dry-electrode lithium-ion batteries and carbon-nanotube ultracapacitor batteries, we could see very soon a huge leap ahead in storage capacity--possibly seven to eight times what is achieved now by 2017-2018. If that prediction becomes reality, the days of petroleum-fueled automobiles will quickly come to an end, and by 2026 many people look back at the "good old days" of petroleum-fueled automobiles with all the attendant local air pollution.

    Interestingly, I think automobile design will change, too. With no more need to cool an internal combustion engine, automobiles will start to become smaller in size externally, but still be quite roomy internally. Automobiles will end up looking akin to today's Honda Fit, Opel Meriva or Toyota Verso S (Ractis).

  20. Re:First Off, Listen to Chris Martenson on US Wants Natural Gas As Major Auto Fuel Option · · Score: 1

    A couple of comments:

    1. Much of the world's potential oilfields haven't been touched, mostly due to current environmental regulations, too harsh weather conditions, or the current limits on oil extraction technology. Geologists know that we've barely touched the potential oil and gas deposits off the North Slope of Alaska, and the continental shelves of the USA--deposits that could add hundreds of billions of barrels of crude oil and trillions of cubic feet of natural gas to the potential US supply. And that's not including the potential to unlock two trillion barrels of oil from oil shale deposits. Right now, Russia is looking at starting to unlock the potential of oil and gas deposits in parts of Siberia that have yet to be explored--deposits that could be just as big as all of the Persian Gulf _combined_ if properly exploited. That could give Russia huge economic clout, and if China can sign an agreement with the Russians, China will no longer need to import oil by tanker--it'll be directly sent to China by pipeline from the oilfields, along with the natural gas. And the Russian ports of Sovetskaya Gavan and Vladivostok could be booming as oil export terminals.

    2. Many of the world's oilfields aren't using the gas or special fluid injection--methods originally developed to extract out highly-viscous California crude oil--to extend the life of oilfields. As such, possibly a third of the oil from older oilfields have yet to be extracted out. This could mean the Persian Gulf may still have a lot of oil yet to be extracted out.

    3. There has been tremendous advances in using oil-laden algae to produce motor fuels in the last ten years. Research is continuing, and over the next decade motor fuels from oil-laden algae could become finally economically competitive with motor fuels from crude oil.

  21. Re:First Off, Listen to Chris Martenson on US Wants Natural Gas As Major Auto Fuel Option · · Score: 1

    I think Martenson is assuming that we won't be advancing oil and natural gas extraction technology anymore.

    Remember, doomsayers have been screaming "Peak Oil!" for over 100 years! But as new oilfields and better extraction technology has come online, the supply of petroleum and natural has gone through the roof. Remember, it's only because of severe Siberian winters that Russia has not explored for more oil and natural gas in eastern Siberia--a place that might hold more oil and natural gas than all of the Persian Gulf _combined_. Here in the USA, we have potentially two trillion barrels of oil locked in oil shale, and once the technology to heat up the shale and pump out the oil "in situ" matures, the USA will in effect become energy independent because we'll no longer need to import oil from anywhere.

    Possibly within 20 years, oil-laden algae could be grown on a large enough scale to produce gasoline (petrol), diesel fuel, heating oil, and jet-fuel quality kerosene--essentially these fuels will come from a renewable resource. Of course, within 20 years electric car battery technology would have advanced enough that very long range electric cars are the norm, and that will substantially cut the need for gasoline and diesel fuel.

    In short, technology is about to out-run the doomsayers again....

  22. Sounds like a good idea but.... on US Wants Natural Gas As Major Auto Fuel Option · · Score: 1

    ....Be aware of the downsides of using compressed natural gas as motor fuel:

    1. You need bigger fuel tanks to get decent range, which will impede on interior space of a motor vehicle.
    2. The fuel tank has to be made strong, either by using heavier metal or quite expensive composite structures.
    3. People need to be aware that natural gas is EXTREMELY explosive (a natural gas explosion is much more destructive than a gasoline explosion) and will need far stricter safety procedures for refueling CNG tanks.

    CNG works best for public transit such as buses, minibuses and taxis, where very long range is not so much an issue.

    This is why we need three things done to make the USA more business friendly:

    1) Review EVERY business regulation "on the books" as US Federal law and see if any of them need to be phased out due to the law being obsolete or unneeded.

    2) Drastically overhaul the income tax code to reduce yearly compliance costs and encourage way more savings and capital investment in the USA. I'd recommend going with the no-loophole 17% flat tax that Steve Forbes proposed back in 1996--a tax system if implemented would send the US economy into the stratosphere within 18 months because it would make the USA one of the world's most friendly places to do business from a tax regulation perspective.

    3) Severely reign in Wall Street by tightening liquidity requirements for investments, increasing the minimum margin requirements for futures trading to 20%, re-impose the 1933 Glass-Steagall Act, and requiring the President, members of the Cabinet, members of Congress or any judge in the US Appeals Court system or the Supreme Court to put into a "blind and dumb" trust all stock and bond holdings or must sell them off.
