    "most regular open relays, for instance, are mal-configured Microsoft and Sendmail SMTP servers"

    Open relays are very 90s. Open relay blacklists have made it much more difficult for open relays to be used. They have moved on to open proxies and virus zombies for exactly that reason: to avoid giving up their unique info. Yes, some still use open relays, but the majority of spammers do not (especially the *successful* spammers; open relay spammers are low impact to the end user because they are usually blocked at the MTA level).

    "do you think that adding $50 ($20 for an ISP, $30 for a domain name) seriously adds that much to the cost of sending spam?"

    Yes. Costs to spam:

    Software: $300, amortized over many spams to become less than $1 per spam. Assumes that more than 300 spams can be sent with the same software (at 1 spam per day, that's less than two years).

    Hardware: $1000, amortized over many spams to become less than $3 per spam. Assumes that over 300 spams can be sent with the same hardware.

    Bandwidth: $40 per month, amortized over a month of spams to less than $2 per spam. Assumes that at least 20 spams can be sent each month (one each workday).

    So for less than $6, one can send out 2,000,000 emails a day (100,000 per hour easily achievable with minimal hardware). Adding $50 to this would substantially increase their costs. Further, if the honeypot blacklists within the hour, that's only 100,000 emails for the $50, not 2,000,000.

    Even if the spammer uses a T1 line, that's still only $1000 per month or $50 per spam. Adding $50 to this would still double their costs.

    If you replace Linux with MS Windows in that statement, it is almost as true. MS Windows is not actually easier to administer *well*. It's roughly the same difficulty as Linux (easier with some tasks; harder with others). The biggest difference is that it is much easier to administer MS Windows *badly* but well enough that things work. With Linux, one has a much better chance of finding a good admin, because the bad admins are more obvious.

    "Outsourced US companies would have no more of a tax disadvantage than domestic US companies"

    But they would still have a disadvantage against *foreign* companies (with lower tax rates) selling in the US or elsewhere.

    Something that people tend to miss in these discussions: the trade deficit is not determined by the cost of goods (which is what this would affect). Goods can increase or decrease in cost without affecting the trade deficit. The trade deficit is caused by the desire for other countries to accumulate American *dollars*.

    So long as other countries find accumulation of dollars useful, they will send us goods in exchange for those dollars. If their goods are overpriced, then exchange rates will fall until their goods are competitively priced. Thus, fiddling with relative prices is never going to provide the results that they desire, as exchange rate effects will eliminate the results of the fiddling. There are only three choices here:

    1. Accept the trade deficit.

    2. Give the dollars to other countries without asking goods in return (i.e. foreign aid; incidentally, this was the path followed in the 1950s).

    3. Remove the reasons why other countries want to accumulate dollars.

    Note that 2 and 3 would cause the American standard of living to fall, as it would require us to make the stuff rather than merely receive it. Further, it is worth noting that the American cost to produce the equivalent goods is often much more expensive than what we are paying other countries (i.e. that $500 billion trade deficit might require $2 trillion of production if we did it). Finally, many of those who are unemployed are not suitable to produce the relevant goods (e.g. VCRs and RAM chips); we would still have to undertake worker retraining, etc.

    In campaigning, both Kerry and Bush ignore these realities. However, I will vote for Kerry because there is at least a chance that he will address the real current problem: many of our most productive and hard working citizens have been activated from reserve status and shipped to Iraq. Thus, we have lost their production during the war. Even if Kerry does not bring this war to a close faster, he is more likely to avoid other wars at the same time.

    You seem to be claiming that spam can be tracked back to the sender. This is manifestly untrue. Most spam can only be traced back to a proxy (which may be a compromised machine). Sure, you can shut down the proxy, but the spammer is not associated with the proxy (at least not in any trackable fashion).

    This is deliberate. Remember, most of their sales are going to be through third parties. If they undercut their resellers, they may lose the reseller. Think of the store as offering you a chance to demo their products while hanging out at the mall.

  13. Re:Why Gateway failed on Sony Quietly Opening Retail Stores · · Score: 1

    "A PC store is just not going to have the volume of sales in a mall setting to support it."

    Neither Sony nor Gateway need to get sales *in* the store to support them. If people visit the store impulsively while in the mall, become convinced that the product is worthwhile, and go home to buy online (or to another store to buy), that's almost as good from Sony's perspective. They manufacture the full line of products, so they make money off anything in the store even if you buy it from a third party. The stores are marketing expenses.

    Gateway had several problems that Sony won't:

    1. They only manufactured computers, which aren't generally high margin (unlike the high end electronics available from Sony). Anything high margin was something they bought from someone else (i.e. Sony makes the manufacturer and retail margins on a plasma TV; Gateway only makes retail markup and only if you buy from them; Sony makes the manufacturer's margin even if you buy from Circuit City or Sears).

    2. Their original model was custom built for a reasonable price. You don't need to go to a store to get something custom built. They couldn't feed that itch for someone who was ready to buy right now. That person would buy an HP (or similar brand) from a retailer (Circuit City, Office Max, Wal-Mart, etc.) instead.

    Computer stores do not have a good model for brick and mortar sales. It's a nice adjunct to TV and stereo sales (or a basis for selling services), but not a good solo model. Computers are better sold over the internet or in department stores, where their low margins are more acceptable. Local computer stores will tend to make their money from service rather than consumer sales.

    What happens if you find a problem? Casinos eat the loss or recover from the tamperer. How do you recover votes? They are not priceable. All your solutions are about minimizing and accepting loss, but I can work around all of them without compromising the polling place (or subsequent vote storage). However, I can easily enough develop a paper based system that can *only* be compromised at the polling place or after. If we add the simple system of having the voters scan their ballots prior to dropping them in the lockbox, we can verify that the actual votes are being cast as intended.

    If you are not confident of the security of your polling places, it is easy enough to become a vote observer. It's a volunteer position after all. Further, due to the transparency of paper based systems, a single "good" poll worker can prevent an entire polling place from compromise. By contrast, a single "bad" person with access to the machines can compromise an entire set of machines. Further, the machines are themselves susceptible to simple error. As Firefox has repeatedly demonstrated, open source will still contain errors. What happens when the error is only noticed after the election?

    Securing a system by adding complexity is foolish. The way to increase security and reliability is to layer simplicity. Complexity counteracts more things but also offers more points of attack. I.e. there are more things that can go wrong.

    Especially if the error is consistently favoring one candidate over the other (e.g. debit favored over credit in your scenario or Bush favored over Gore in the last presidential election). If 1% of Bush votes are being counted for Kerry and 1% of Kerry votes are being counted for Bush, that's not a big deal. However, if an error causes 4% of Bush voters to vote for Bush and 4% of Kerry voters to vote for Nader, then that is a problem.

However, it did not. Bush voters who read the ballot the same way that the Gore voters who miscast their votes (for Buchanan) did still cast their votes for Bush.

    This is not an engineering problem. All vote systems will be susceptible to human error. What is important is to add a management system to catch the error and allow it to be rectified. The simple way to do this is to have the voter stick their ballot in the machine to be scored. Then, they could have seen that their vote was going to Buchanan rather than Gore and fixed the problem.

    A system that kept people from voting if they couldn't understand the ballot would have been better than what actually happened.
