Since the list is kind of quiet, I had to work my way through the
market numbers on Linux tonight for a guy in Germany on the sci.econ
newsgroup, (it was a testosterone thing, as you can surmise from the

FYI, ...


BTW, what it says is that NT is becoming increasingly vulnerable-its
to a 50/50 turning point in the way the market evolves in the future,
(and its an increasing returns scenario-its one of those kinds of
things where the sum of the parts above the 50/50 point is larger than
the whole; an NP hard algorithm kind of thing.) The next year, or so,
(maybe less,) is very important, (probably the most important in its
history,) for Linux, and will tell-the-tale. It also says that
expanding market share of the likes of Apple, Be, *BSD, etc., is very
important, and in Linux's best interest. On the other hand, it says
that the desktop is not vulnerable to Linux, unless it can do so by
leveraging its past gains against NT-which means there is a
confrontation in the very near future with Win2K. At any rate, you can
find why I picked the Gambler's Ruin scenario to model it at:

At any rate, Arthur acknowledges that the concept of increasing
returns is not new. On page 4 of the HBR citation:

    Glimpsing some of these properties in 1939, John Hicks warned that
    admitting increasing returns would lead to "the wreckage of the
    greater part of economic theory."

and goes on to argue that Hicks had mis-assessed the issues-increasing
returns does not destroy the general/traditional theory of economics;
it complements it.


BTW, I have had some success in modeling the dynamics of increasing
returns in business and industrial markets with the Gambler's Ruin,
(eg., like increasing returns in business, the player with limited
capital has little chance against the casino, even if it is a perfect
50/50 chance game.) In the traditional Gambler's Ruin, the player's
capital, over time, is a Brownian motion fractal. Adding
leptokurtosis, makes it even worse-and the player/business with the
smallest resources/market share has a very definite disadvantage.

As an example, Linux is supposed to have about 10 million installed
seats; Microsoft's Win9X about 90 million, (depending on who is
telling the story, of course.) So, using those numbers, in the
Gambler's Ruin, Linux's chance of *_EVER_* becoming dominant would be
10 / 90 = 11%, but the duration of the "game" in installed seats would
be 10 million * (90 million - 10 million), or virtually
indefinite-ie., the market is locked in a fairly static
situation. However, for NT, (AKA, Win2K,) NT has about 35% of the
market, Linux 17%, (IDG numbers,) and the chances of Linux dominating
NT is almost 50%, (or MS has a 1 in 2 chance of loosing that market to
Linux,) comparatively, a much more favorable state of affairs for
Linux. But, suppose there were 10 players in the desktop market, each
with 10 million seats, and Microsoft with 90 million. Then, it becomes
a probability that Microsoft will loose its dominant position, 0.89^10
= about a one in three of surviving with its market intact.

So, from this POV, an oligopoly is not sufficient to prevent
"monopolistic" control of the market-it has to be a panoply.
