    > Geometric ?, is that a word ?

    Yes. A geometric progression is one in which the second-order
    operation[1] is used rather than the first-order operation[2] to
    process each element of the progression in order to acquire the
    subsequent element. When charted on a cartesian visualization
    system, a geometric progression will be parabolic; whereas, an
    arithmetic progression would be linear.

    There are of course higher-order progression classes than the
    geometric class; by leveraging a higher-order operation it is
    possible to achieve progression performance on a scale that will
    cause the competition to revisit their benchmarks. The gamma
    progression is generally considered the market leader going
    forward in this regard. By incorporating integration of this
    function into your gameplan, you can achieve results-driven
    core competency in the progressions market.

    [1] Colloquially, "multiplication", although any second-order
    function will do; it does not have to be traditional
    Real-number multiplication.

    [2] Colloquially, "addition", but with the same qualification

    taken to using taint checking for many things, and I'm working on

    In Perl, the equivalent is undef, it stringifies to "" or numifies

    Read the article. Those are just the bounces that got *forwarded*
    correctly. The vast majority of the bounces were directed back to
    the (faked) From addresses; a small percentage of technically savvy
    victims figured out where the junk originated and set up automatic
    forwarding back to there; this is the 5880 number.

    I don't know exactly what percentage that would be of the total
    bounces. It would of course be a very small percentage of the
    victims who would figure stuff out and set up the .forward --
    certainly less than 1%. However, 5% of the people get 95% of the
    spam, so it might be a somewhat higher percentage of the bounced
    messages. It's hard to say. 1% is probably a fair bet, in terms
    of being within an order of ten (that is, the true percentage is
    very likely between .1% and 10%). Which means between 58800 and
    5880000 bounces -- rounding, we can guess between sixty thousand
    and six million bounces were generated by this outfit's activity

    medium resolution, BTW. 640x480 was the very best resolution
