  1. Re:National level? on Bill Confirming Property Rights For Asteroid Miners Passes the Senate (examiner.com) · · Score: 3, Insightful

    Other space-faring nations are unlikely to challenge America on this issue, because they have an interest in staking their own claims. Since the asteroid belt contains more than 100 million cubic miles of ore, weighing several quadrillion tonnes, there should be enough to share. Space is big, and there is plenty of stuff out there.

  2. But don't worry- I'm sure that'll be fixed in ver. 2.0

    If America is actively targeting and attacking Russian submarines, that means that WWIII has started, and there ain't gonna be no version 2.0.

    ... smaller, dolphin-size drones forward-deployed to search for the enemy.

    Russian subs can move at a sustained speed of 35 knots, and can go 45 knots for short periods. At that speed, a dolphin-size drone would quickly run out of fuel. To track the sub over the sound of its own engines, the drone would have to use active sonar, so the Russians would know it was there. Before a separate strike vessel could arrive, they could either destroy the drone, or outrun and evade.

    Problem is, at some point, there's an interface between the hardware and the software, and I have access to the software, and can rewrite it to always get a positive from the hardware

    If you have physical access to the hardware and the software then NO authentication is effective. There is no such thing as a secure device in hostile hands.

    Or am I completely off base here?

    Yes. Authentication schemes are designed assuming that random people do not have access to the communications between an ATM and the bank. That is generally a valid assumption.

    The U.S. Marines are making great use of them.

    There are a number of military advantages to hovercraft that don't apply to civilian applications:
    1. They can move up onto the beach
    2. They can move over coral reefs and submerged obstacles
    3. They can move over minefields (the pressure is too dispersed to detonate them)
    But there are also drawbacks:
    1. They are expensive
    2. They require a lot of maintenance
    3. They have a lot of downtime
    4. They are difficult to operate
    5. They are dangerous: they can drift sideways in a turn, and they don't stop quickly.

    The "attribution" is just speculation. They have no actual evidence.

    In other words, is mathematics a fundamental part of the fabric of reality (i.e. Platonism)?

    Another way to ask this question: If we make contact with an advanced alien civilization, would they have "math" similar to ours? They will use different numerical symbols, and likely not use base-10, but would they otherwise have the same basic concepts of zero, rational numbers, transcendental numbers, theorems, proofs, etc?

    I fail to see how this is different from many of the comments made by US Republicans about the Obama administration.

    It isn't different. That is the whole point. Israel has long enjoyed bipartisan support in America. But the Netanyahu administration is putting that all at risk by closely aligning with only the right wing of the Republican Party. This will benefit Israel in the short run, since the Republicans control congress. It also benefits the Republican Party, as Jewish votes increasingly shift from Democrat to Republican. But it will hurt Israel in the long run, as young voters are alienated, and the American electorate becomes more Hispanic and Asian (people that have little sympathy for Israel).

    I would rather we spent the money on useful construction jobs, like repairing our failing bridges

    Since "the money" would have come from the oil industry, there is 0% chance of it being spent on repairing bridges. More likely, it will be spent on pipelines to carry Canadian oil to the Pacific coast, so it can be shipped to China.

    This is a victory for political symbolism over reality.

    What is different about the extension approval process that it see more success than the creation of newer, safer reactors?

    Because the extension of an existing reactor is WAY cheaper than building a new reactor. New reactors are not cost competitive with shale gas. Watts Bar is only being completed because they have a guaranteed price for their power. If they had to sell power at market rates, the project would have been cancelled years ago.

    If your company's work environment includes anger and yelling, then you certainly should test for that in the interview process. But in a company that values professionalism and reliable code, I don't see any point in testing for "performance under stress".

    So you've never coded something that worked fine until it went into production on that one machine that was slightly different then your dev and staging machines?

    I have been in situations like that occasionally. Never did it involve someone standing over me, shouting, or telling me to "hurry up". That is unprofessional and counter-productive. My boss knew that the problem would be fixed fastest if he gave me clear directions, a quiet place to work, and then left me alone with no interruptions.

    Why is "performance under stress" a relevant metric? I do almost all my coding alone in a quiet office, and can't imagine a realistic situation that would have someone looking over my shoulder and telling me to hurry up.

    When I conduct interviews, I try to remove the stress. I give the candidate a test problem, and a quiet cubicle to work in. Then I come back in 30 minutes and ask them to show me their solution. If you only test them on a whiteboard, in front of a nitpicking audience, you are just weeding out the introverts, not the bad programmers.

  21. And someone else could coerce you to prove you voted how they wanted you to.

    Almost no election fraud involves coercing votes one individual at a time. You are focused on the mouse in the room rather than the elephant.

    A secret ballot needs to be anonymous to all, including the person who made the ballot once they have left the poling place.

    You have have a totally secret election, or you can have a verifiable election. But you can't have both.

  22. how did you get a "wallet" or account number to serve as being able to cast a vote and not vote more than once?

    The fact that you voted would not be secret, nor is it secret now (at least in the USA). Only how you voted is secret. You could use a private key to verify that the vote recorded was how you actually voted.

    whoever gave you that knows who you are and can link that data to determine your vote.

    A better question is "Why delete it?" Keeping it involves near zero effort and near zero cost. If deciding what to delete takes more than a few seconds, it is not cost effective. I have every email I have sent or received for the last 30 years (except for spam) and it fits in 10 cents worth of storage. Even if you count backups and redundant copies, it is under $1. My archive has come in handy many times, including helping a third party dismiss a $150,000 lawsuit from a patent troll by documenting prior art. That was worth $1.
