    The solution would seem to be to rely on less polluting energy generation mechanisms, since the fossil fuels are inherently less cost effective over time anyway.

    The problem is there's a very vocal and politically active group which opposes the one power generation solution we already have which solves the problem - nuclear power.

    Environmentalists suffer from what I call Just Right-itis. The insistence that there is just the right amount of global warming occurring. Enough that mankind is in mortal danger, so we have to take drastic action quickly. But not so much that we need to switch to a different power source ASAP. Instead there's just the right amount of global warming so that we can spend decades developing completely new power sources, meanwhile continuing to burn fossil fuels thus exacerbating the problem.

    It's like finding out a asteroid will hit the Earth in a few decades and wipe out all life on it. But then staunchly opposing deflecting the asteroid using existing technology which is already capable of dealing with it, and instead insisting that completely new technology be developed to deal with the asteroid. This reasoning only makes sense if you value your pet technology over the survival of life on Earth. Their primary goal isn't stopping and arresting global warming. It's using it as a vehicle to drive the transition to renewable power, even if that means risking all life on Earth.

    Nuclear power doesn't have to be the end game. The #1 priority should be getting off fossil fuels. We can do that with nuclear, buying ourselves decades if not centuries to develop renewables and batteries until they're in a state which can handle base load. Then we can switch from nuclear to renewables. If you oppose this most rational course of action, then you force us to start coming up with more and more desperate ideas to stave off disaster, like polluting the atmosphere in order to save it.

    Cutting our military budget by 90% would put us down near Ghana and Nigeria. U.S. military spending is huge simply because the U.S. economy is huge.

    Calls to slash military spending made sense in the 1950s and 1960s. But currently it's just slightly above the world average. If you account for Japan and NATO (whom we're obligated to defend by treaty), it's pretty much at the world average.

    BTW, the biggest budget items are Social Security, and Medicare/Medicaid. They're the programs whose growth is bursting our budget, and what we need to get under control if you want to pay for everyone to go to college. Even if you completely eliminated 100% of military spending, entitlement growth in the next 20 years or so would eat up all that savings. Like it has already eaten up the savings from cutting the military budget from the 1950s/1960s.

    I highly recommend you read the CBO long-term budget projections to understand what exactly is causing excessive growth in government spending.

  6. Note that the solution proposed by Google and accepted by the EU is to auction slots in the special shopping area at the top of the search results page, not to offer anything for free.

    Auctioning slots does no good when Google is one of the bidders. Google can just bid $1 trillion for each slot. Since it's Google paying Google, their net cost is zero no matter what they bid. (Actually, if you take opportunity cost into account, their net cost is whatever the next highest bid was, since they are foregoing that revenue to advertise their product instead. Except that's how it works currently. They don't make any ad revenue listing competing shopping comparison sites, so they lose nothing by adopting a strategy which results in them not accepting any ad revenue from competing shopping comparison sites.)

    I'm pretty critical of most of the EU actions against Google, but I fully support them on this one (just not with them accepting the proposed solution). If Google is going to run a search engine, its results should be agnostic, not biased towards their own product or against their competitors'.

    How many city transport systems make a profit?
    It is perfectly normal for subways to only get a fraction of their income from ticket sales. And for governments to fund the system from taxes, just like the roads.

    Making a profit is what tells you that the value of the service being offered exceeds the cost of providing the service. If a city transport system isn't able to pay for itself entirely via fares, then it's costing the city more to maintain it than the value it's giving citizens.

    If you're forced to use general fund taxes to support the public transport system, then it becomes a subsidized service. Someone who doesn't use it is paying so riders can use it at a discounted price. Your road analogy is wrong because road construction and maintenance is paid for by fuel taxes, which are also paid for by people using the roads.

    The only role of government in creating these types of systems is in getting over the initial payment hump (the construction of the lines and purchase of the buses/trains), and coordinating the payments of the millions of riders. Once you start justifying supporting such systems via general tax funds instead of fares, you're justifying government waste.

    nm aren't comparable between companies. Each foundry is referring to a different thing when they call their process "x nm".

Meanwhile, the 10nm process Intel was working on yielded 100 million transistors per mm^2, indicating its average component size was smaller despite having a larger nm name.

  11. The multiple cameras are performing two functions, both of which save weight and improve image quality.
    • Having two identical cameras spaced apart (to generate parallax) allows you to computationally generate an image equivalent to if the photo were shot with a bigger (heavier, more expensive) single lens. Most notably, this allows blurring the background for more pleasing portraits. I've got huge 70-200mm f/2.8 lens on my DSLR for this purpose. You do NOT want something that big stuck to your phone.
    • Prime lenses (single focal length optics) have superior image quality to zooms. Primes are also less complex to design optically, resulting in a smaller lens.

    So having two wide-angle cameras and two telephoto cameras on your phone duplicates a single big professional-quality zoom with a large aperture, but without the weight and expense. Unlike the display PPI war, the reason for these extra cameras is functional.

    The curved screens most certainly do make sense, just perhaps not in your typical usage. They had their inception in Korea. The larger Galaxy Note phones were extremely popular among women there who'd slap a case on it, and carry the phone in their purses. Unfortunately, when they got a SMS, they had to open the purse, pull the phone out, and flip open the cover tor read the text message. By having a curved screen on the edge which could display a preview of the text, the woman could simply open the purse and peek at the phone to see what the text was.

    I'd agree that at this point it's mostly become a marketing gimmick.

    Not just modern companies. In a graduate software engineering class I took (mumble mumble) years ago we had a rather vigorous discussion about people versus process. That is, if you have a sufficiently sophisticated and well implemented process, do the people matter that much? And the reverse, if you have sufficiently excellent people, does the process matter that much?

    If the job is mind-numbingly simple, then the people are no more than cogs, and the process is what's important. Given enough technology, the people could be replaced with robots.

    If the job requires abstract and creative thought, then it can't be solved by an algorithmic process, and it's the people who are important. Even with magical levels of technology, a person will still be needed to do the job because it requires abstract reasoning to make the necessary decisions.

    That's why there's little point lamenting the manufacturing jobs which got shipped overseas. For the most part they were the former type. If they hadn't gone overseas, they would've eventually been eliminated by automation (many already would have been if the unions hadn't opposed automation in the 1980s and 1990s). What's important for the future of the job market is to cultivate the latter type of jobs, and to educate the population to be able to perform those jobs. e.g. Instead of assembling and welding car parts, a person is needed who can design, troubleshoot, and/or repair a robot which assembles and welds car parts.

Unlike Windows which still has a color profile bug dating back to Vista (a UAC elevation popup which dims your desktop will dump the current color profile). And OS X is based on Unix so doesn't suffer as many audio dropouts as Windows used to, making it the preferred platform for sound sampling. So Macs tend to be overrepresented in what these people produce - movies, videos, DJing. When a scene calls for a laptop, these people will usually just grab whatever is most easily available, which is usually a Macbook.

    Apple also offers its products for free for use in movies. They take em back after, but it helps if your production's prop budget is limited.

    If you walk into any other business, 99% of their computers run Windows. That said, OS X has managed to claw above 10% market share in recent years.

    * This is also why Macs got high-PPI "retina" screens first. Page layout artists also predominantly use Macs. Subpixel rendering, which basically triples the horizontal resolution without requiring new hardware, was introduced with Windows XP (ClearType). So Windows didn't need high-PPI to produce high-quality fonts. But subpixel rendering requires you to align the fonts to the subpixel grid. That's unacceptable for page layout work, where having the font appear where it'll actually appear when printed is more important than how sharp it looks on the screen. Consequently, OS X didn't use subpixel rendering (If you plugged a 1024x768 or 1280x800 monitor into a Windows PC, then a Mac, the Windows PC was noticeably sharper). OS X fonts are blurrier, but they're placed more accurately for page layout artists. The only recourse Apple had was to sharpen fonts was to switch to high-PPI displays.
