  1. Re:DON'T THEY KNOW ANYTHING ABOUT STATISTICS? on British DNA Database Mismatch · · Score: 1

    Hmm I think your reasoning is a little sloppy.
    Firstly you assume that each on the loci is
    statistically independent, I'd guess not.
    Secondly you assume that all gel locations
    are equally probable, this has to be wrong, I'd
    guess the distribution is highly skewed towards a
    small subset of locations.
    The article itself states that adding four
    additional loci takes you from 1 in 37e6 to 1 in
    1e9 an inprovement of a factor of 27 or 2.3 per
    loci, a long way from 600!
    There must be a strong case of diminishing returns
    here, so even the 13 loci tests used in the US are
    probably not much better than 10 loci test
    mentioned in the article.

  2. Its not 1 in 37e6 its 1 in 56 duh.. on British DNA Database Mismatch · · Score: 1

    Its difficult to believe that bonafide scientist
    could be so stupid. If they have 660,000 records
    on file, and the chance of a random match is
    1 in 37e6, then the chance of matchng someone at
    random in the entire database is
    1 in 37e6/660,000 = 1 in 56. The bigger the database gets the worse the problem.
    If they have been using such "evidence" to put
    people away, they must have hundreds of innocents
    in the slammer by now.

  3. Infinite wavelengths. on Canada Builds World's Fastest Network · · Score: 1

    Infinite number wavelengths does not imply infinite bandwidth, the max thoretical bandwidth for an optical fiber is on the order of several 100Tb/s, still pretty big. Ok, back to the fun
    stuff...

  4. Why bother with the the venture hassle. on Techweb article on Google · · Score: 1

    I'd recommend that the just sell shares in the
    company to ordinary folk, just like Real Goods
    and Sam Adams did. Make an offer on slashdot
    and have people sign up on their web site. I'd
    be in for a few hundred bucks if they did this.
    I bet they could raise a mil without breaking into
    a sweat. Might be a good way to expand slashdot
    as well :-) I don't think all of the reporting
    hassles kick in until the shares are publicly
    traded...
