  1. Re:um on Comcast May Raise Prices On "Internet Hogs" · · Score: 1

    The problem with taxes is that everybody likes the benefits but nobody wants to pay 'em.
    To expand: It's very hard to agree on what is a truly fair way of assigning the tax burden. You can start from any number of plausible-sounding positions (everyone gets equal benefits therefore everyone should contribute equally, everyone should pay based on what they earn, everyone should pay based on what they can afford...) and wind up with wildly different conclusions. You can argue that any given demographic is paying too much tax, or not enough.
    Given that (a) the US is a democracy, (b) you can pretty much rely on individuals to fight their corner to pay less tax, and (c) there are fewer rich people but they have more influence, it's likely that the current broad approach is close to optimal. Won't seem that way to any single person (who'll almost always feel that they're paying too much to make up for some other guys not paying enough), but society as a whole settles on a balance.

  2. NT to OpenBSD on OpenBSD 2.9 Released · · Score: 1

    Actually...

    I moved from NT to OpenBSD about a year and a half back. (Kind of a radical switch, eh? :) I had previous experience as a sysadmin, which helped a lot, but relatively little working with UNIXes. I found it surprisingly logical and easy to get used to, believe it or not. So I wonder whether the trickiness of moving from Linux to Open is as much to do with unlearning Linux habits as Open's relative starkness.

    And that's where a lot of environmentalists go wrong. Instead of focusing on the real problem, which is cleaning up messes, they choose to focus on limiting technology, progress and convenience.

    Environmentalists should focus on clean production of energy, not reducing the production of energy.

    The trouble is, clean production of energy isn't sufficient - heck, it's already possible and the problem's still there. Fossil fuels may be dirty (and in limited supply in the long term) but they're gosh-darned-awful cheap and convenient. As long as consumers - especially in the US - insist on their current lifestyle at its current monetary cost, they will need to burn ever-increasing quantities of fuel.*

    What continually staggers me is the mindset. Developing alternative energy sources is an expensive business that takes years and years. Reducing consumption has immediate effect, cutting down on pollution without side effects and _saves_ money to boot. So why on earth is the US's oil use going up year on year? It just doesn't make sense to me.

    I guess the summary of what I'm trying to say is: The real problem is not cleaning up messes, though that's important. The _real_ problem is stopping ourselves from making more of them - an ounce of prevention being worth a pound of cure and so on.

  5. Re:Margin Of Error? on Florida Election Votes Certified · · Score: 1

    Hi. First, a disclaimer: I am not a statistician. However, I am a scientist and I deal with statistics and uncertainties on data on a daily basis. That said:


    There's not supposed to be *any* margin of error in the actual vote.


    In an ideal world, possibly. But we don't live in an ideal world, and even if we did the actual vote isn't what we really want to know.

    Let's take a step back. What is our experiment (the Florida part of the election, ignoring the wider one) trying to determine? Well, we want to know which candidate is supported by most citizens. That's not what we measure, though; we only count votes from people who made it to the polling station and cast their vote successfully. We're losing some of our sample right off the bat - we don't know how they would have voted. We can try and estimate by supposing that they're split the same way as in the people whose votes we did collect but there's an uncertainty there.

    (Of course, it's debatable how many of the people who didn't vote were actually abstaining - in which group I include "couldn't be bothered" folks - and how many were genuinely unable to vote because of ill health, lack of transport, being turned away from the polling station or what-have-you. Furthermore, we don't know if those people are uniformly scattered across the population - in which case we've just got a random error - or whether there's a systematic trend at work; systematic errors are very nasty because they grow right along with your sample whereas random errors grow more slowly. You may have two million votes but if there's a systematic error of 2% they won't help you.)

    So there's some inherent uncertainty which is (a) unavoidable, and (b) of unknown size. On top of that there *will* be random counting errors. It's difficult to get an exact estimate without knowing how the voting machinery worked and doing calibration studies but as a rough guide the error in counting N tends to be of order SQRT(N). There'll be a prefactor which will be large if the measuring process is inaccurate and small if it's accurate. A perfect infallible voting system would make this zero, but such a beast does not exist (see comp.risks) and even if it did it would have to be operated by fallible humans.

  7. Re:Ug. Social Engineering! on The Full Nader Plus a Taste of Bush and Gore · · Score: 1

    I whole-heartedly believe that the people who think those who make more should pay a higher percentage of their income are completely mathematically illiterate.

    First off, any taxation system is going to be somewhat arbitrary; while most (but definitely not all) people would agree that some pooling of citizens' resources is a good idea, opinions on who should contribute what to those resources and how they should be gathered vary wildly. So any statements about whether a system is fair are going to be highly subjective.

    One simplistic example (with exaggerated figures plucked out of the air) which could justify a variable tax rate would go something like:

    Fred and Jim are neighbours. Both have basic, unavoidable living expenses of $18,000 per year - food, rent, mortgage repayments and so on. Fred earns $25,000 a year and Jim earns $27,000 - not much more. Yet if both are hit by a tax of 20%, Jim's disposable income ($3,600) is nearly double Fred's ($2000). A fairer method, one could argue, would be to apply a fixed-percentage tax to what's left after basic expenses - perhaps 65% in this toy example. That would correspond to Fred paying taxes equivalent to 18.2% on his total income and Jim paying 21.7%.

    Of course, this approach doesn't scale well - Bill, who earns $50,000, would say his living expenses are higher than Fred and Jim's because he has to make payments on his new SUV. Fred and Jim might argue that this is a luxury rather than a basic expense - but what are they going to say to Joe who only earns $15,000 and thinks that having a car at all is a luxury?

    In other words, I'm not proposing this as a serious, workable system, just as a thought-experiment illustrating one reason why some people might consider varying tax rates fairer. (People who actually know something about economics may now chew it to pieces.)

    I mean, what if the SAME stats proved that Black(or Hispanic, or whatever the politically correct terms are... sorry.) people get in more accidents than white people? Well, obviously, there would be minority groups protesting as far as the eye can see.

    Actually...

    I remember hearing in the BBC Reith Lectures (from 1998, I think) the speaker describing almost exactly this situation. I tried to find a transcript on the BBC site but failed, I'm afraid.

    The speaker was, I believe, the Professor for racial studies at a prominent US university. When she'd moved house, she had applied for a mortgage over the telephone and been quoted a figure for premiums to be paid. The company had sent her a form - already filled in based on what she'd said on the phone - for her to sign as confirmation.

    Now, although the Professor was black she had, as she put it, a "white voice" - so the person taking her phone call had ticked the White/Caucasian box in the Ethnic Origin section on her form. The speaker described how she toyed with the idea of just leaving it be, but decided in the end to correct the mistake before returning the form.

    The quoted figure for the premiums went up.

    What had happened was _not_ that the mortgage-lender had arbitrarily increased them because she was black. Rather, the information about her was fed as statistical data into the company's projections for property values in the neighbourhood - and because there was a statistical correlation between black people moving into an area and value dropping subsequently, the estimated risk of lending to anyone moving there went up - and therefore so did the premiums.

    Operationally, that looks pretty much like discrimination to me. So I'm afraid that minority groups do experience the sharp end of amorally-wielded statistics too.

    How do the statistics of Japan compare to that part of the US population that considers itself Japanese American?

    All good questions - I don't know the answers. (I presented those countries' statistics because they're the only ones I had. Sure, this isn't the whole picture, but it's better than none of it. If you want to know the answers to the questions you were posing, a good webcrawl is probably in order.)

    The point I was responding to was that Switzerland has lots of guns, but has (from the US's point of view) a low firearm homicide rate - the implication being that that rate is exclusively dependent on cultural factors. Those stats show that both Switzerland and the US actually have quite a high firearm homicide rate compared to the UK (where I am) - the "lowness" of Switzerland's figure is just relative.

    What do we conclude from this?

    Well, strictly speaking all we can say is that the firearm homicide rate doesn't depend exclusively on availability. I think we can go a bit further and say that it does to some extent - Switzerland's rate is rather high for an otherwise extremely law-abiding country.

    (The reason I've not commented on the figure for Japan, in case you're wondering, is that I have basically no real knowledge of Japanese culture and don't feel I can make useful contributions there.)

Second, try an install or two in VMware first if you can - the install routine can be a bit unfriendly the first time, but is efficient once you've got used to it.

Several bits of server are integrated and ready to go - Apache, OpenSSH and Sendmail, for instance - but if you're looking to use it as a workstation, you'll need to add quite a few apps.
