  1. Quantum cryptography? on Quantum Measurements Leave Schrödinger's Cat Alive · · Score: 4, Interesting

    What? Isn't the proven destructiveness of measuring a quantum system the bedrock of quantum key distribution?

    It's not clear what Obama wants, other than canceling the Bush tax cuts for the rich, but unfortunately that won't raise enough revenue.

    I think the secret plan is to let the Bush Tax Cuts expire for everybody (not just the rich) after the economy starts to recover and inflation becomes a concern. And the reason he's not talking about it is because of the election next month.

    Or maybe I am just wishful-thinking out loud here. But if the recession ends (increasing the tax base and decreasing the demand on social safety net) and if we could get back to moderately higher taxes (Reagan-era, or at least Clinton) and avoid any major new military escapades, things will be OK.

    Even Intel's OLD processors are holding value. I have a Core 2 duo system I was considering upgrading to Core 2 quad, but their cost - new or used - is almost the same as it was when they were released 4 years ago.

    For example the Q9550s released at $369 and now sells for around $300.

    I guess you could argue the high resale value makes it very cheap to own so long as you remember to sell it a few years later.

  6. Re:Fondue party! on What Happened To Diaspora, the Facebook Killer? It's Complicated · · Score: 2, Interesting

    The problem is that it is a student project that intended to start from zero and kept largely to itself.

    My theory of the problem is that a walled garden will always provide at least a little smoother experience than a decentralized, open, free one. Thus usenet gave way to moderated web forums, decentralized email largely gave way to centralized webmail providers and twitter, home pages gave way to myspace/facebook, and beowulf clusters gave way to EC2. Open standards and decentralized implementations are losing ground all around.

  9. Re:Guns on The Explosive Growth of 3D Printing · · Score: 2

    Sorry shit for brains, the vast majority of firearms used by the cartels don't come from America

    Why do you think that? Have you looked at the evidence:

    Research has asserted that most weapons and arms trafficked into Mexico are from gun dealers in the United States.[132] In response to a 2009 GAO report that claimed 87% of Mexican crime guns traced to U.S. origins, the DHS pointed out that DHS officials believe that the 87 percent statistic is misleading (i.e.: out of approximately 30,000 weapons seized in Mexico, approximately 4,000 could be traced and 87 percent of those-3,480-originated in the United States).[133]

    So, there is some room for argument, but what is known does not look too good.

    those that do are given to YOUR military, where they are subsequently taken by the cartels.

    Again, why do you think that? It is well known that thousands of guns are bought by mules and illegally exported to Mexico all the time. (You don't honestly think that Fast-and-Furious was dreamt up for no reason? Or that illegal exports somehow stopped because the effort to trace the guns stopped?)

    That said, there is no real link to 3d Printing here. 3d printers can't make the crucial parts of a gun, and there is no shortage of factory-made guns.

  10. Re:Government Economists on US Agricultural Economists Say Bacon Shortage Is Hogwash · · Score: 1

    Don't know the difference between shortage and rationing as a result of price controls.

    The difference is that under rationing everybody still gets some, whereas under market pricing people with money can keep having all they want because those with less money get none.

    And, yes, I know that price controls outside special circumstances lead to a reduction of supply longer-term, and are bad. But it is ignorant to think a price hike won't force some people to go without. Many people in the world cannot simply choose to pay more.

    I'd be interested to hear what uses people have found for the advanced features of BTRFS. (BTRFS snapshots on a RAID1 volume seem like a great /home partition?) Since BTRFS is gradually evolving it's kind of hard to get a grasp of what is currently available and trustworthy (although this approach is vastly preferable to Microsoft's approach to revolutionizing the filesystem - aim high and never deliver!)

    ...if we could invest in things that would lead to higher growth.

    What would that be? It doesn't seem to me there is a shortage of capital to invest; interest rates are absurdly low. A company can borrow money to grow almost interest-free. And the stock market is so loaded up with money that has nowhere else to go, that now we're just getting investment bubbles with little if any long-term growth. How about investing in education? There are millions of new college graduates who can't demand a high enough salary to repay the costs of their education.

    You can see I'd be a lousy politician because I do not see the solution. Where do we go from here?

    Yes each person brings something different to the job. Often so different that I am at a loss to say whether one person is "better" or "worse" than another who is at least in some sense their predecessor. And you know what? Maybe Facebook would now be worth $104,001,000,000 instead of $104,000,000,000 if it had not fired Noah Kagan, and firing him was a mistake. Then again maybe not. There is no way of knowing and nobody at Facebook cares. That is what replaceable means.

    The single best take-home message in the post is nothing new, but have you truly internalized it? You are replaceable, and firing you would hurt you much more than the company.

    so you want to subsidize phone calls by overcharging on data...

    You assume voice and data are ultimately different things. If providers simply charged for data (which may or may not happen be voice), and competed on $/megabyte, then making a phonecall would be vanishingly cheap, and texts even moreso.

    I realize I just said something different than the Indian telecomm minister, who things voice should be completely free. But I think simply dropping the mostly mental distinction between voice and data accomplishes almost the same thing and makes more sense.

    Teaching methodology (pedagogy) is a technology. We need to develop it into a science, whereas now it is a craft - clearly is not well understood, given the never-ending debates over how to best educate people. From the article:

    MIT and Harvard are designing edX to be as much a tool for educational research as a digital teaching platform, Anant Agarwal says. Scholars are already beginning to use data from the system to test hypotheses about how people learn, and as the portfolio of courses grows, the opportunities for research will proliferate.

    Granted this data will be confounded with the limited, computer-based methods of instruction it requires, so your point is valid. But at least the people working in this area are well aware they are biting off several different problems at once.

    The answer is yes. The reason we don't have government-backed digital cash is because currency that is not inherently traceable makes it harder to regulate trade, and some trade is illegal. Same reason they stopped making large-denomination paper currency - it's most useful to dictators and drug dealers. And also for under-the-table (or "underground economy") business that would be otherwise be legal except it can't be regulated and taxed. And before you start, no, I'm not saying cash or digital cash should be outlawed. But it certainly raises some tough issues.
