    Isn't that like someone just making another entrance to your house and then painting it over to match the brickwork..?

    Check out the Underhanded C Contest. Sure, a patch containing, "if(packet_csum=SEKRUT_FBI_BACKD00R_P4KT) { /* d0 3v1Lz */ }" would get noticed pretty quickly. But good security is really subtle; it's probably difficult, but not impossible, to make proper-looking code that actually screws up in just the right places. The main problem is that anything that subtle is as likely to get broken accidentally as well.

    The bank should know that these scams are going on. They should know that some of their customers are likely to fall for them, thinking that they've deposited valid funds.

    At least some banks do. After I finished school, I worked remotely for a company in California for about a year as an independent contractor, which involved me billing them every two weeks and them mailing me a check. A couple of times, just based on the financial situation (or me being a day late in billing and having no paycheck for another two weeks), I had to ask the cashier if they'd make the money available immediately (i.e., not wait for the check to clear). They'd seen small-time check-caching scams before ("I'll buy your junker car for $1000, here's a check for $2000 write me a check for the difference"), so always asked if I was sure the check would go through. "They always have" seemed to be enough for them to let me take the risk if I wanted to.

    But yeah, seems like saying "it's clear" when it wasn't really clear is totally messed up. The guy may have been thinking, "It's probably a scam, but what the heck -- if the check doesn't clear, I won't give them any money. What's the risk?"

    How did Obama get elected?

    Obama got elected because his researchers identified a specific "market segment" of voters which they managed to go after without alienating their "base voters". That "market segment" were people who were fed up with the system as it was currently running, and the animosity that went on in Washington. He promised Change. This segment then voted for him.

    Unfortunately, (1) it takes two people to stop being petty and forge partnerships; and it certainly wasn't in the interest of Republicans to do so (2) many of the things he's promised he hasn't even attempted to do (more open government, for instance) (3) some thing he just consistently lied about, like his record on abortion; but most people in the "market segment" who were pro-life didn't notice.

    I wouldn't call Obama's election a victory by the "little guy"; I'd call it a coup of marketing strategy.

    Try it with numbers.

    So (as I understand it), at anyone time there are any number of outstanding bids. If the last sale was at 50.00, there may be bids to buy at (for example) 49.50, 49.90, 49.95, and 49.98, and bids to sell at 50.02 50.05 50.10 and 50.50. So the "bid-offer spread" is $0.04 (50.02-48.98).

    The only way this could reduce the spread is if they transact on one side, and move towards the other side. I.e., if they buy at $50.02 and sell at $50.01, or sell at $49.98 and then bid at $49.99. But in both cases that would be a stupid thing to do: they'd be losing money.

    What people are describing instead is "knowing the future"; i.e., they see an incoming sell for 48.99 and also an incoming bid for 50.01. So instead of letting the bid and the sell match up, they buy at 48.99 and sell at 50.01, making $0.02.

    However, this transaction doesn't add any liquidity -- if the HFT hadn't been there, then the transaction would have gone through anyway; either the buyer or the seller (or both) would get the difference between the bid and sell prices, rather than the HFT seller getting it.

    I'm certainly not an expert, and I'm willing to be corrected on my understanding of how stock trading and HFT work. But so far all you've done is wave terminology around in a way that makes me think I understand trading better than you do.

    thus making the market more liquid

    "Liquid" means easier to buy and sell, yes? For example, your house may be worth $250K, but if I just walked up and offered you $250K, you probably wouldn't take it because you don't really want to sell it right now. If I was determined to have your house, I'd have to offer you enough of a premium to make you sell it anyway. Having lots of people buying and selling means that there's always someone willing to buy or sell at a reasonable price if you're a real investor rather than just a day trader. I'm not 100% convinced whether that's true (or whether the benefit is worth the cost even if it is true), but at least it's plausible.

    But in HFT, isn't it the case that they see a price, purchase some really quickly, and then sell it again at a slightly different price? So they're not actually adding any liquidity. If there was no one there to purchase from, then the HFT trade system couldn't buy it from anyone to sell to you; and if there is someone to purchase from, then without the HFT system, you could just buy it from the original seller. So the HFT system doesn't add any liquidity, as far as I can tell.

    Regarding "a better system": What do you mean by "better"? The end goal of all economics is merely organizational: we have people and resources, and we just need to organize everyone's effort in using the resources in a way that maximizes everyone's happiness. The current system often works well for that, but it's 100% clear that the current system also fails pretty often as well: it causes all kinds of waste, unhappiness, and long-term damage -- wasted money and effort put into building houses no one is going to buy, wasted labor from people being out of work, damaged environments and brands due to short-term-gain long-term-loss thinking, risky behaviors, &c. If it was a little more difficult to buy and sell investments, but we had fewer recessions and bubbles, and people who owned stocks genuinely felt responsible for the long-term effects of what the company did, I think the world would be a much better place.

    The objective is to make money for the charity, so more money can be given out. It does not matter to the foundation if that's an American business or not, just that it has to be profitable. If African companies are not profitable then the foundation will simply squander the money away.

    I think some of what's missing in the whole stock-market type investment thing is that people typically look at only one outcome for their investment: money (aka "shareholder value"). The problem with this is that it often leads to various degrees of evil behavior; often the very problems that the foundations themselves are giving money to try to solve.

    If everyone, especially large charitable foundations like Bill Gates set up, tried to evaluate not just the value on the stock market, but how much good or evil the companies they'd invested in was doing, then we'd be living in a very different world from the one we are now. And arguably, a foundation with $40B could do more good overall by choosing investments specifically to optimize both for shareholder value and good of people, than it could by simply donating the income to explicit charities without asking how that money was made.

    and has always been about making people feel secure.

    On the contrary, it's about making people feel less secure.

    It's a well-established principle of cognitive behavioral therapy (CBT) that acting on a fear helps maintain that fear. People who are afraid someone will break into their house may check the locks on doors and windows ten times a day; they think it makes them feel safer, but really it maintains the fear that someone may break in. Reducing these "safety behaviors" reduces the fear, and in some cases causes the phobia to vanish entirely.

    So going through all this extra hassle reinforces in people's minds the idea that at any moment, any plane may blow up and take them down. It makes us not only more willing to spend money and put up with privacy checks; it encourages us to tolerate and support the "war on terror", and privacy violations in other areas (i.e., illegal wiretaps, &c).

    Yes yes if you're good you get to go to heaven,

    Just FYI, that's how a lot of religions work, but it's not how Christianity works. It says that you can't be good enough to get to heaven. You've done wrong things in the past, and you will continue to do wrong things in the future; the only way to get forgiveness for those is through Jesus' death on the cross. I quote:

    "No one can ever be made right with God by doing what the law commands [i.e., being good]. The law [i.e., all our ideas about what's right and wrong] simply shows us how sinful we are. But now God has shown us a way to be made right with him without keeping the requirements of the law... We are made right with God by placing our faith in Jesus Christ. And this is true for everyone who believes, no matter who we are. For everyone has sinned [i.e., done what was wrong]; we all fall short of God's glorious standard. Yet God, with undeserved kindness, declares that we are righteous." (Paul, Letter to the Romans, 3:20-24)

    Regarding "earthly reassurance", Paul goes on to address this specifically:

    "When we were utterly helpless, Christ came at just the right time and died for us sinners. Now, most people would not be willing to die for an upright person, though someone might perhaps be willing to die for a person who is especially good. But God showed his great love for us by sending Christ to die for us while we were still sinners. And since we have been made right in God's sight by the blood of Christ, he will certainly save us from God's condemnation. For since our friendship with God was restored by the death of his son while we were still enemies, we will certainly be saved through the life of his son. So now we can rejoice in our wonderful new relationship with God because our Lord Jesus Christ has made us friends with God." (ibid, 5:6-11)

    In other words: God doesn't want you to "be good", he wants you to trust and follow him. God didn't wait for you to come to him, he came to you. Jesus left heaven, lived on earth, and died a death of torture and shame to try to save you. If he's willing to go through all that before you're even trying to follow him, you can believe that once you are trying to follow him, he'll do anything in his power to keep you on the path to Heaven.

    Just sayin'. :-)

    Unlike the peering relationship between Level 3 and Comcast, Comcast and Akamai, which had previously delivered Netflix's streaming video, had a commercial arrangement, a source close to Comcast confirmed. In other words, instead of swapping traffic between Comcast and Akamai for free, Comcast charged Akamai a fee to deliver its traffic including the Netflix video content.

    Notice that the dispute is not between Comcast and Netflix -- it's between Comcast and Level3, which doesn't create content, only owns pipes. Level3 and Comcast have a "peer" agreement; they generate a similar amount of traffic, so they accept each others' traffic for free. That's a typical arrangement. However, this was before Netflix changed CDN from Akamai to Level3. Akamai sends much more traffic to Comcast than it receives, so it pays Comcast for receiving the traffic. That's also a typical arrangement. Now that Neflix will be going over Level3 instead, Comcast is just trying to negotiate the same deal w/ Level3 as with Comcast:

    "Comcast offered Level 3 the same terms it offers to Level 3's CDN competitors for the same traffic," Waz said.
