But at the same time I'm sure most people would rather see the books go to those that will enjoy reading/owning them rather than some guy who is vulturing thru the tables looking for something he can resell.

The book will inevitably go to someone who will enjoy reading it; it just won't be the person who bought it at the sale.

I mean, a library is all about being free for everyone. And to have someone come in and try to profit from their operations is distasteful.

If the library wants to ensure the book is available to everyone, not just people who are wealthy enough to buy used books online, the obvious solution is to keep it in their circulating collection.

Remember, people with six figure incomes pay less then the rest of us because they get taxed at capital gains rates, which can be as low as 15%. Real working people pay around %30 or more.

Six figures? What is this, the 1970s? Of course, the bulk of income earned by people making six figures is taxed at ordinary income tax rates: wages, self-employment income, etc. Intuitively, you have far, far more people with six figure incomes from employment than retired and drawing six figures from investments, or young people drawing six figures from trust funds; and also six figures is way below point of things like hedge fund managers arranging things such that most of their income is in the form of capital gains.

Here is data from the IRS on sources of income classified by AGI. I selected 2006 so you can't say that capital gains are low due to the recession, which started in 2007. As you can see, for the 12 million returns with AGI from $100K to $200K, 3.6% of the income was from qualified dividends and net long-term capital gains. For the 3 million returns from $200K to $500K, it was 8.1%, for the 600 thousand from $500K to $1M, it was 12.0%. A large majority of "six figure income" people hardly have any income taxed at the special 15% rate. Obviously you are correct that someone making a large portion of their income in capital gains and dividends will pay a lower tax rate than many people making their money from wages, but overall it is not until well into the seven figures that the average effective tax rate starts going down.

Table sugar is pure sucrose, for all intent and purpose.

And sucrose is a disaccharide composed of fructose and glucose--i.e., 50% fructose. It's broken down by sucrase in the small intestine. Sucrose may well be substantially healthier than HFCS, but it's perfectly valid for a somewhat knowledgable person to want to know what the reason for the difference is. You haven't helped in that regard.

I'm not convinced that you understand how credit cards work, or for that matter, how money works.

And I think you're being willfully obtuse.

Doesn't matter if it's your bank or your credit card company, it's YOUR money that's gone. With a debit card the money comes out of your bank, with a credit card the money initially comes from the credit company, who sends you a bill, and you send them money from your bank. In either case you can file paperwork claiming fraud, and in both cases a valid claim of fraud will result in your money being returned. (specific policies vary by company and bank)

When you receive a bill, there is no force of nature causing you to send payment. Here's how it works with a debit card:

  1. Money is stolen via your card, coming immediately from your bank account.
  2. You notice the discrepancy (perhaps because you want to withdraw money you expected to have but don't, in which case it sucks to be you).
  3. You ask the bank to return or restore the money, claiming fraud.
  4. (a) The bank returns the money, or (b) the bank denies the claim.

In case 4(a), you have no access to the money in the time between 3 and 4(a), which could be 10 business days (two weeks). In 4(b), it is up to you to pursue legal action against the bank.

Here's how it works with a credit card:

  1. Money is stolen via your card, being paid from the card company's accounts.
  2. You receive a bill including the fraudulent charge (note: the company is asking you for money, rather than vice versa).
  3. You make a claim for fraud.
  4. You send a payment only for the non-fraudulent amounts.
  5. (a) The company accepts your claim, and that's the end of it, or (b) they deny your claim, so you keep getting bills and other collection action.

In 5(b), it's up to the company to pursue legal action against you, rather than vice versa. In all cases, the money remains in your control at least until the company wins in court. (Of course, you would lose the money with the debit card as well if you lost against the bank in court, but the money would have remained out of your control immediately.)

The point is clear: your money is gone with a debit card in that you lose actual control of it, and have to ask for it back. The card company's money is gone with a credit card because they have to ask you for it back (perhaps not entirely, if they haven't paid the merchant yet, but that's not your concern).

Nuclear Energy Now More Expensive Than Solar 635

Posted by samzenpus
from the sunlight-is-free dept.
js_sebastian writes "According to an article on the New York Times, a historical cross-over has occurred because of the declining costs of solar vs. the increasing costs of nuclear energy: solar, hardly the cheapest of renewable technologies, is now cheaper than nuclear, at around 16 cents per kilowatt hour. Furthermore, the NY Times reports that financial markets will not finance the construction of nuclear power plants unless the risk of default (which is historically as high as 50 percent for the nuclear industry) is externalized to someone else through federal loan guarantees or ratepayer funding. The bottom line seems to be that nuclear is simply not competitive, and the push from the US government to subsidize it seems to be forcing the wrong choice on the market."

So, let me see if I have this straight. Suppose it is a crime to fail to disclose the existence of asbestos when selling a property (completely separate from cleanup). In that case, the authorities should charge the CURRENT OWNER, Jafafa Hots, with failing to disclose the existence of asbestos when the property was sold, since the OWNER took on ALL the liabilities when they purchase the property. Similarly, if I create a bogus company, for the sole purpose of scamming investors, and con a total of 5 investors, A, B, C, D, and E, into buying shares, they should be fined for defrauding investors A, B, C, D, and E. Should the SEC continue to exist? It wastes a lot of time "protecting" investors, even though you have proven that it is categorically impossible for an investor to be a victim of the company's actions.

Way to completely ignore the point. Your parent post was pointing out that in this particular story, where Dell is paying a fine for defrauding people who bought their stock, it is perverse to claim that the current stockholders should be treated as personally liable. You brought up an unrelated example where the victims were not the stockholders. To be clear, you are claiming that when a company is fined for using a secret slush fund to smooth out its earnings, thereby defrauding people who newly bought its stock, the penalty should fall on the current stockholders. I think quite the opposite. No publicly traded company should pay a dime in any sort of investment fraud case--any penalties should be paid by management.

That was how it was used by both Bruce Schneier and RSA themselves in articles about the subject. I'll go with their usage. I realize that in a way that is "appeal to authority", but in this case there is little doubt that they are greater authorities on the subject than you or I.

Argggh. However, I think I'm right at least as to symmetric ciphers. I've never heard brute force refer to anything that doesn't treat the algorithm as a black box in that case.

No, it isn't. I know what a theory is, and so do you. The difference is in the phrase "currently known". It is "currently known" that in theory (real theory, you have yourself written about it) quantum quantum computing could be quite useful in brute-forcing some systems. In that respect the sentence I quoted is just plain incorrect. If it was meant in a different way, it should have been written in a different way. I will concede that it may not be "currently known" to be useful against AES-256 and the like, but the sentence clearly says "any algorithm", which is just as clearly (ref: sources we have already discussed) incorrect.

It is true that there is a sweet spot in key length where brute force by a classical computer is infeasible but by a quantum computer it is feasible in theory. What people usually mean by quantum computers not being useful for brute force is that, for any algorithm with adequate choices of key length, where the time is linear in key length or close to it, if key length N is infeasible for classical computers to brute force and you're worried about quantum computers, you can simply choose 2*N. (I have no reason to think you disagree with these statements, I'm just saying what people probably mean.)

And that's all fine, but that isn't the way I was using the word. At least I never meant to use it that way. If I have, please refresh my memory. [...] So wherever the "blame" lies, if such there be, we do not disagree so much after all. It was more of a communication problem than anything else.

I sure as hell do not plan on reading through again to figure out the blame and/or argue about it.

There is no sound basis today for saying we "know" how to do the most efficient quantum computing, even in theory. We don't even know how many different types of particles there are, or their properties!

The problem is the way physical laws are updated with new knowledge. Nineteenth century physics was correct in normal human situations. We know at least it was wrong at the samll scale, high speeds, or high gravity. It was the small scale issues that were technologically revolutionary (e.g., semiconductors and probably quantum computers at some point), because there are no inherent resource problems with building small things. Currently, QM really looks correct at normal small scale situations. Where things break down is high engergies and also high gravity is still not solidly understood. So, this is all very exciting for physics, but we won't end up with a Tevatron on everyone's desk. It's pretty clear I consider new computing due to new physics more science fictional than you (although it's clearly possible). Thus, I'm not inclined to say it has to be related to QM as opposed to small black holes or wormholes or the like.

You can't carve your way to success without cutting remarks.
