  1. Re:Scaremongering on Japan Activated Air Raid Sirens During North Korea's Missile Test Monday (cnn.com) · · Score: 5, Informative

    There is no political reason. The U.S. would be involved whether or not they activated the sirens. The U.S. is obligated by treaties wrapping up the loose ends of WWII to provide for Japan's defense against foreign attack. The treaties and Japanese Constitution limit Japan's military to operating domestically to repel an invasion. The JSDF is not allowed to operate outside Japan, though that clause has been stretched recently to allow Japan to participate in UN peacekeeping missions. Since that leaves Japan extremely vulnerable to foreign attack, the treaties make defending Japan from outside Japan's borders the responsibility of the U.S.

    So in this particular case (foreign missile overflying Japan), not only is a U.S. response warranted, it's required.

    You know, if you push this idea to its logical conclusion, you end up with a train. And we already have those. Plus, since friction of metal wheels on metal rails is a lot less than friction of rubber pneumatic tires on asphalt, the train is even more energy efficient.

    I can understand the desire to reduce loading/unloading times by transporting goods by trucks which can all split up to different delivery addresses when they reach their destination city. But you have to remember that a long convoy of trucks imposes an externalized cost onto other cars on the highway. They have to wait for the convoy to pass before they can get into that lane so they can exit, or incur additional risk of injury or death by speeding up to try to get in front of the convoy. If you really have enough stuff going to the same city that you need multiple trucks to carry everything, just put it onto a train and transfer it to trucks at the destination city.

    Every crowd-funded project I've seen has a blurb at the end saying that it may fail and you may lose your money.

    But I agree with you that crowdfunding (in its current state) is just a half-assed version of venture capitalism where the project owner retains 100% ownership and control, instead of having to share it with the people putting up the money. I've only "contributed" to two projects - one was an art project, and the other was for a device which I always wondered why it didn't exist and the project already had a working prototype.

    I look at crowdfunding and I start to understand why a minimum wage is important. The problem isn't that employers are greedy. It's that a subset of job-seekers are stupid and will agree to work for a lot less than their labor is worth, consequently driving down the prevailing wage for everyone. As long as this subset willingly contributes to crowdfunded projects for nothing more than a promise for the completed product (which might not even happen), crowdfunding is going to continue in this sorry state. As an initial investor, you should get partial ownership of the resulting company (even if a minority share so the owner retains full operational control). That way if the owner eventually sells for $2 billion, the initial investors share in that windfall instead of the owner pocketing everything.

  8. Unlike a conventional telephone or internet cable, which can be tapped without the sender or recipient being aware, a QKD network alerts both users to any tampering with the system as soon as it occurs.

    The bitrate for quantum encryption is too slow to actually use it to encrypt the data you're transmitting. Instead, you use it to encrypt a key which you transmit to the recipient. The data is then encrypted via standard cryptography using that key - basically a one-time pad. That's why it's called Quantum Key Distribution. SSH and I believe OpenVPN do the same thing.

    So someone evesdropping in on the key distribution would be detected. But there's nothing to stop someone from capturing the encrypted data stream, then getting a copy of the distributed key after the QKD happens (e.g. if the recipient computer has been altered to transmit the key back to the attacker). At that point they can use the key to decrypt the data stream after the fact. In other words, the key distribution is secure, but protecting that key after it's been distributed still has the same vulnerabilities.

If you already paid for the license to a copyrighted work, it shouldn't matter to the content creator how you get it.

    So the way to maximize the value of a copyrighted work to society is for everyone to get a copy. But if everyone gets a copy for free, then there's no incentive for people to create new works. So we set up a system where for a short time creators have exclusive rights to distribute their works in exchange for money. Once that time expires, it falls into the public domain, and the entire public gets the benefit of the formerly copyrighted work.

    Unfortunately, copyright holders have managed to get this time extended to a ridiculously long duration. Currently about 120 years (average remaining lifespan at time of creation + 70 years). Can you even name a dozen copyrighted works which were created 100-120 years ago? The duration is so ridiculously long that by the time copyrighted works fall into the public domain, they have next to zero value to society remaining, thus defeating the whole purpose of copyright. I'm not sure what the correct duration should be. 8 years seems too short. But it sure as hell isn't 120 years.

  15. Re:Be careful of that calculation on Higher Minimum Wages Bring Automation and Job Losses, Study Suggests (axios.com) · · Score: 2

    The problem is that the benefits are not linear. You can easily see that by going to the limits of the policy - when all manufacturing is done in China and all workers are out of a job, for instance.

    That's not what happens. The only way U.S. companies could move all manufacturing to China is if they're able to import and sell all those manufactured goods back here in the U.S. So in that scenario, the U.S. has no more manufacturing jobs, but has sufficient design, service, and other jobs to sustain the consumption of all those manufactured goods.

    For the "all workers are out of a job" scenario you outline to be true, there would also have to be no manufacturing for U.S. companies to move to China. If that were to actually happen, we'd have a reversal - lots of idle potential workers in the U.S. means manufacturing wages here would drop below that of China. And manufacturing jobs would move from China back to the U.S. So the "all workers are out of a job" scenario can't really happen. Unless of course you implement a minimum wage high enough to guarantee that it's always cheaper to manufacture in China.

    The economy isn't trying to "punish" U.S. workers. All it sees is a geographic wage disparity (lower wages in China than in the U.S.). It tries to correct this by moving jobs from the high-wage region to the low-wage region. This results in wages in the low-wage region increasing as the people's productivity there increases. The end-state is both China and the U.S. having high wages. Whether wages in the U.S. end up higher or lower depends on whether earlier wages were based on actual productivity (end-state wages are higher because of stronger trade partners), or based on the U.S. exploiting foreign countries (end-state wages are lower because the U.S. can no longer exploit foreign countries).

    My argument against offshoring wouldn't be that it's bad. It's actually good (I don't believe the U.S. is primarily exploitative, so I think the end-state for the U.S. is an improvement over the current state). My argument against it would be that it's happening too quickly. Offshoring is fine, but it needs to be done slowly enough to give laid-off workers time to retrain and find non-manufacturing jobs. That would allow the economy to keep humming along despite the loss of manufacturing jobs. Not too slowly though, or you end up with what happened between the 1980s and 1990s - unions thwarted factory automation in order to preserve manual labor manufacturing jobs. So when cheap Chinese labor became available, the manufacturing jobs and factories moved to China. If U.S. factories had been allowed to automate in the 1980s, perhaps the overall cost of manufacturing in automated factories in the U.S. would've remained lower than manufacturing with manual labor in China, and at least we'd still have factories employing Americans overseeing the robots.

    It's not a linear function

    Correct.

    • If you go to one extreme (no minimum wage), you end up with widespread worker exploitation. (Based on historical evidence.) And overall productivity suffers. (Evidenced by Ford's business booming when he set his wages much higher than the prevailing wage. Indicative that low wages were hurting overall economic productivity, and raising them increased productivity.)
    • If you go to the other extreme (minimum wage higher than the average wage), you break the economy. (Based on Greece. Actually the economy will just devalue your currency until your fixed minimum wage equals the actual productivity of the people at that wage. So this can't really happen unless people keep trying to increase the minimum wage. Or in Greece's case, because their currency's value was fixed based on other countries' economies. OTOH if you try to fix prices to prevent this, then the economy grinds to a halt - nobody is going to sell stuff for less than what it cost them
