I'm old enough, and well-known enough, that you can draw conclusions about my
behavior with little difficulty.  If you think it wrong to challenge someone
that makes
completely wrong statements every day here, then I suppose that is your opinion.
 However,
it is not my "style" to let false statement after false statement pass.
Particularly when many
of these "false statements" are directed toward me.  I don't see a thing wrong
with a "shut up or
put up" when a clearly false statement is made, and there is a trivial
methodology available to
prove the falseness of the statement.

A couple of examples:

1.  Hyper-threading makes a program go _slower_ not faster.  Eugene and I both
have access
to SMT machines.  We both posted results to the contrary.  But Vincent, with no
SMT machine
he can use, directly contradicts both of us.  Even saying that no processor with
SMT is
available.  When I have one sitting in my office and have since Thanksgiving.

2.  Crafty using two processors is no faster than Crafty using one processor.
Eugene (again),
myself, and _others_ quickly posted test runs proving this was false.  Crafty
generally runs
about 1.7X faster on two processors over a large set of positions, something
_anybody_ can
verify.

3.  The "smp-lock" stuff in Crafty is killing it's performance.  Even though
that lock is used
two to three thousand times _total_ in a 3 minute search, even though the code
protected by that
lock takes all of a few microseconds (at absolute worst case) to run one time.
Even though the
parallel speedup is perfectly reasonable using four and eight threads.  Etc.

4.  Vincent "killed all 1997 programs."  That is false on two fronts.  First, he
_never_ "killed_
Crafty in 1997.  He was lucky to win one game of ten at blitz time controls.  He
was lucky to
win one game of five at long time controls.  He played many games.  He made
excuses each
time he lost.  But he _still_ lost.  I offered him yet another chance to prove
this claim and he
has refused, although he continues to make the claim.

The list goes on.  And each time he is wrong.  And he is _proven_ wrong.  And
once he is proven
wrong, he disappears, only to pop up in another thread, making another
outrageous claim, where
he is again called on it and the disappearing act happens again.  Over and over.

Meanwhile, back at the moderator ranch, the lone ranger, disguised as a pool
table, keeps getting
his balls racked.  We have gotten more requests to ban Vincent than any other
_five_ members
combined.  And we have not done so for reasons that are probably not very clear
nor very sound.

So now, as Paul Harvey says, "you know the _rest_ of the story."

pretty it ain't...
