  1. Which media? on Ban On Price Floors Abandoned, Internet Prices May Rise · · Score: 1

    I'd say blame the media. They're the ones who made more of Gore's "wooden appearance" than of Bush's cocaine use, his many business failures or the fact he dodged Vietnam.
    Which media? Surely you don't mean the liberal MSM, do you? ;)
  2. Not sure how serious you're being... on Bigelow Aerospace Deploys Genesis 2 Space Module · · Score: 2, Informative
    However, from Wikipedia:

    Bigelow Aerospace was founded by Robert Bigelow and is funded by the fortune Bigelow gained through his ownership of the hotel chain Budget Suites of America."
    Hence the whole idea of a "space hotel" seems appropriate...

  6. Addendum on Will Linux Win the Next Presidential Election? · · Score: 1

    Btw, now that one can RTFA (no fault of yours if you didn't read it before), it turns out that there are 4 Republican campaigns running on Linux and 9 running on Windows. As for the Democrats, there are 7* runing on Linux, 1 running on Windows, and 2 running on BSD. That makes this even less likely to be due soley to random chance. (As you'll see elsewhere, under the old assumptions it was already slightly less than 1% due to pure chance.)

    This is not to imply some big Windows/Linux controversy. All I am arguing is that it is not purely random. There are lots of possibily non-sinister, non-controversial explanations for how this could come to be, many of which have been discussed elsewhere.

    *This includes Al Gore, for some odd reason. In fact, looking at the entire list, there are probably other dubious inclusion. If you want to argue that this is non-meaningful, your best recourse is to argue for cherry-picking the data. As I have no way of knowing how the data were picked, I can't argue effectively against that. :)

  7. Fisher's exact test on Will Linux Win the Next Presidential Election? · · Score: 1

    The .9% value you arrived at agrees very closely with the 1/104 value that I arrived at by applying Fisher's Exact Test. Since I also derived a totally different value (14%) using a self-invented naive method, I'm inclined to believe that my math in doing the Fisher's Exact Test was not wrong, but that my self-invented naive method was either too naive or suffered from a mathematical mistake itself.

  8. I wasn't considering any factors other than random on Will Linux Win the Next Presidential Election? · · Score: 1

    All I was saying was that it seemed unlikely that it was random. Once you've ruled out random, you're free to explore other hypotheses. You'll note there are several already floating out there, but I'll choose to remain agnostic as to what the "real" reason(s) are.

  9. Not a big difference on Will Linux Win the Next Presidential Election? · · Score: 1
    You'll notice that the assumption I preferred was that 1/3 of the hosts ran a MS OS, so that's not far off from 35%.

    Also the decision is usually not random but based on how the candidate can get the best deal. In most cases the only reason you would be using microsoft as the host on your website is if your website was being provided to you by a large corporation that has its own servers and uses microsoft; because the management is only familiar with microsoft project and wants to keep everything consistant.
    I was arguing exactly that it wasn't random, although I was remaining agnostic as to the rationale.
  10. Yes, thank you on Will Linux Win the Next Presidential Election? · · Score: 1

    That's what I was thinking of, although I think it was just called a "Fisher's test" back when I (sort of) learned it. Interestingly enough, when I assume there are 9 Democrats (as I did in my other calculation), I get p=1/104, or about 1%. (For the first "box" I get 9/1768, and for the second "box" (there are only two), I get 1/221, and 9/1768+1/221=1/104. So, either my original assumptions (which also requires an a priori assumption that this does not) were way off, or my calculations here are messed up.

  11. Re:Significance is in the eye of the beholder... on Will Linux Win the Next Presidential Election? · · Score: 1

    1 in 7 is not statistically significant?
    First, let's assume (for sake of argument) that this wasn't a post-hoc analysis (requiring more rigorous analysis). I can't imagine you'd find any journal that would publish results that have a 1-in-7 chance of being the result of "good luck". 1-in-7 is "interesting", as in "deserves further research". It's not significant, at least not to me. (You're fundamentally, right, of course, that what is "significant" is not a hard line that one can draw in the sand.)

    And what if I think that 20% or 50% is significant?
    Obviously, with a post-hoc analysis, 50% is not just insignificant, it's not even interesting. (It's like flipping a coin, and after the coin lands heads, saying "wow, that coin seems to be biased towards heads".) Even discarding the post-hoc component, you've gone from getting lucky with a die coming up a "6" to a coin coming up "heads". If you do two such studies, you'd expect one of them to be 50% "significant".

    Not everyone runs their experiments at the book-generated, easily available 10%, 5%, 1%, etc. levels of statistical signficance. Maybe 15% or 20% will be ok for me.

    You may want to look into Nonparametric statistics. Not everyone can take 30 samples and look at the chart on the inner cover of the STAT101 book for the results... (example : how much stress can a 10' gear costing $10,000 take before breaking? I doubt that they will give you 30 of them to break...)

    I could definitely do with a statistics refresher (and expander) course. I took a "graduate-level" introduction to statistics course here at UVA (designed for engineers, no less), and it was a joke. The amount of time spent discussing how to calculate the median made me want to gouge my eyes out with my fingers. That said, you'll notice that I did "roll my own distribution" and found it wanting.

  12. Right on Will Linux Win the Next Presidential Election? · · Score: 1

  13. Unlikely, but not significant on Will Linux Win the Next Presidential Election? · · Score: 2, Interesting

    Referring to my other calculations, one could argue that the chances of this happening by chance are about 1 in 7. So, yes, as you say, not statistically significant. What is interesting is that Hillary (arguably the most conservative Democrat) is the one Democratic Windows user, and two of the four Republican Linux users are Ron Paul and John McCain. So, I do not believe it is "pure randomness", but that hypothesis cannot be ruled out. (I.e., you're absolutely correct in every sense.)

    That last equation should read q^9 + 9pq^8, or about 14%.

  15. Yes, the Student test was the wrong one on Will Linux Win the Next Presidential Election? · · Score: 1

    I forgot the one I'm thinking of, however. Here's the gist: for sake of argument, let's assume that there are 9 Democratic candidates. If we now naively assume that the odds are 50/50 then the probability of having less than 2 Democrats using Windows is 9/2^9, or approximately 1.8%. If instead, we assume that the odds are 1/3 (the average over both groups), then the probability of less than 2 Democrats using Windows is q^9 + 8pq^8 (p=1/3, q=2/3), or about 13%. So, it doesn't pass the 5% threshold, but it does seem quite unlikely.

  16. Perhaps your bias is showing? on Will Linux Win the Next Presidential Election? · · Score: 1, Insightful

    You're only commenting on the Republican side. I was referring to the discrepancy between the Democrats (1 out of X) and the Republicans (5 out of 9). As I implied elsewhere, I'm sure a Student's t-test would show this to be quite statistically significant. (Unfortunately, I can't RTFA to figure out what "X" is, but I'm guessing it's also about 9.) Also, your implied assumption is a priori 50/50 odds, which seems like a hell of an assumption. (Comparing the two groups requires no such assumption.)

  19. Sounds significant to me on Will Linux Win the Next Presidential Election? · · Score: 2, Interesting

    I don't plan on doing a students t-test or anything, but these results seem pretty significant to me. You're right that the candidates probably don't know what operating system their web server is running, so instead it speaks more to the kind of people they hire to run their web servers. One can easily make generalizations about both groups, so I'll leave that as an exercise for the reader.

One of the things that people plan on doing on Blue Gene is simulating an entire human brain.

  22. An easier way on Scientist Calls Mars a Terraforming Target · · Score: 1

    I think it would be easier (relatively speaking) to find comets that provided the appropriate concentrations of CO2/H20/etc. to replenish the "leaking" atmosphere than to try to provide enough additional mass and/or magnetic field to retain the atmosphere indefinitely. (OTOH, increasing the gravity serves two purposes of course.)

    Her ideas are complex, and have many interesting ramifications - just like Karl Marx. Now I realize that in most ways she was the antithesis of Karl Marx, but IMNSHO she makes the same fundamental mistake as Karl Marx - she appears to place too much faith in her fellow human being. Of course, I've only read one book (Anthem) by her, so I'm definitely no expert on her thinking. I'm basing this mainly on that book (recently read), but I'm also basing it on how her "supporters" describe her philosophy (which largely agrees with what I got out of the book).

  25. Not quite that simple on Scientist Calls Mars a Terraforming Target · · Score: 1

    Venus, like Mars, also has a very weak magnetic field. It's a combination of factors (including gravity), of which the magnetic field is an important component. Also, the magnetic field protects from long-term stripping of the atmosphere (i.e., over hundreds of millions of years), so as long as we could continue to replenish the atmosphere (at a very low rate), it could work. I'm no planetary specialist, though, so take that with a grain of salt.
