\_ It started as a spoof of hardcore neocons who seemed to

derived from "shell bang"..."

\_ Not the same person either.
\_ Did he say anything about not disbanding the Iraqi army? If

\_ Dear Mr. Card,
I am sorry that you were not born in a time when America had
stand-up enemies to fight (like the Nazis). I, too, wish that America
had an enemy that would unite us in a universal morality, an enemey
that we could point to as a negative reflection of everything that we
stand for. Then we could point to that great enemy and say, We are
the opposite of that. We could declare ourselves the good and the
right in the face of utter evil.
Unfortunately, all of our enemies these days exist on the
fringes of morality. Many of them are our children come back to
haunt us. Few of them have the military might or geopolitical will to
inspire much more than a street-to-street city gunfight or individual
suicide bomb attacks. None of them are the bogey-men we need to truly
galvanize the nation (and the world) into the world-wide benevolent
dictatorship that we need.
Neither do we have the leadership to truly lead us in a
benevolent world-wide dictatorship dedicated to the betterment of
humanity. There are no wise Hegemons to bring us to a new
Enlightenment; no Hari Seldons have stepped up to guide us to our true
potential as the rightful rulers and benificent caretakers of our
planet and our quadrant of space. No, our leaders, both Republicans
and Democrats, are much more interested in the short-term gain in
power of the next four years and the long-term acquisition of profit
for the foreseeable future than they are in the betterment of mankind.
Our leaders have allowed themselves to be led by past grudges and
debts of honor to follow bad counsel from weak and self-serving
sycophants.
It is right and good to want a strong, united America. It is
wrong and bad to mistake brutality for strength and sheepish
acquiescence for loyalty. It is criminal to turn a blind eye to
corporate greed and war profiteering especially when it is done in the
name of building democracy. We owe it to ourselves and the America
we dream of to open our eyes and see the wrong done in our name as
well as the good. Only by doing this do we have any hope of seeing
that America come to pass.
Yours,
erikred
\_ Funny you use Nazis. They were on the fringe of morality in
their time. Evil always trys to make itself look moral.
\_ that is the problem, the word "evil." Nothing is black n
white, there is no such thing as absolute evil. You need
to learn that, eventhough most people learned that at age of 4.
\_ I wonder how many victims of violent crimes are moral
relativists. I wonder how many people who saw their children
tortured and killed in front of their eyes agree with you.
Moral relativism is a product of a safe and prosperous age.
It was easy to believe in evil when you had to face it every
day. -- ilyas
\_ Evil exists but it's not a phantom force floating around.
It's simply the case when people decide not to respect the
rights of others in the pursuit of their own goals. Nazi
Germany did some evil things, but then so did the USA, Russia,
and Israel. Nations generally have more reasonable rationales
for their actions than sadistic psychos whose "goals" are
merely enjoying the infliction of suffering and pain. It seems
to be the norm historically that cultures have different
standards of ethics towards outsiders, often glorifying the
destruction of other tribes.
\_ I must respectfully disagree. - Cthulhu
\_ I must disagree also - George W. Bush
\_ w00t!
\_ No, there really are people who will just cause pain, or
steal, or do any other number of ethically repugant
things for fun or profit. If they want to do it on a
large scale, they will rationalize it with pretty words,
but it's still evil. Besides, it there's no such thing
as universal morals, why don't we just nuke thw whole
middle east and be done with it? |

\_ And here I've been thinking that "comprehensive
review" is just court approved smoke screen
for "let's accept members of privileged
minority classes rather than members of
nonprivileged minority classes". Silly me.
\_ Somewhat related question. There have been many studies along
the lines of: send in white and black candidates for job/loan/
apt/whatever and observe white candidates getting better
response. Has there been a study where they sent in college
applications for black and white students of identical background/
grades/scores/recommendations/etc. and observe the admission
results?
\_ the scariest study of that nature I saw was one in which
computer-generatred resumes were sent to perspective employers
with fake randomized personal and profesional information, but
with some having "black sounding" names that are typically
associated with african americans, and some having more WASP
sounding names.
\_ Well who would this benefit? That's why it won't be studied.
Merit-based admission is the dream, but won't happen until
the educational playing field is leveled - which will be
never.
\_ Gee, isn't it worthwhile to find out if there's racial
discrimination in the college application process?
Color me curious.
\_ It would be interesting if we can attach a value for being
a member of <minority> in the college application process.
Someone enterprising might be able to take advantage of
that. A very straight friend joined all the usual gay/
lesbian/bi/transexual clubs as part of his med school
application process and got into some pretty impressive
schools that he thought he'd have no chance at. With no
control, it's hard to know what the effect of his club
membership might have had, but it'd be an intersting thing
to find out, no?

4/21 Doonesbury's got me wondering: are there any stats for the number
of soldiers maimed in the current war? I've heard the new body
armor is superb at protecting the torso, but that means (potentially)
more soldiers losing limbs instead of dying. Does "700 dead" tell a
reasonably accurate story?
\_ An old article, but it does begin to address your query.
http://www.guardian.co.uk/Iraq/Story/0,2763,1041822,00.html
I would imagine the numbers have increased quite a bit given the
past month's events. -- ulysses
\_ 700 is not purely accurate no matter how you slice it. It's just
the number dead in Iraq from hostile and non-hostile action. The
number of wounded is a much higher ratio than most war conflicts
due to improved body armor, equipment, supply, and tactics.

4/21 A tangent from the underrepresented minorities in CS/EECS
thread below: Why don't many Cal grads apply/get Marshalls
or Rhodes Scholarships? In my experience teaching at both
Ivy League and BIg Ten universities, it's certainly not
that Cal undergrads aren't up to it. COuld it be that
the university doesn't do enough to promote the
scholarships (the RHodes interview, from what I've heard
requires a bit of coaching)? Or that perfectly accomplished
& brilliant Cal undergrads, after four years of getting
their egos bashed, just want to apply to grad/prof.
school and move on with their lives? Just speculating. -elizp
\_ I believe it is mostly because Cal undergrads have
a lower opinion of themselves than is warranted. -ausman
(in general of course, there are many exceptions)
\_ That sounds right.
Remember, boys & girls: don't let the system get
you down. Seriously. -elizp
\_ After a few years at Cal, I felt pretty bashed. Then I entered
the real world where falling into the 92% range wasn't an "F"
any more and recovered. In fact, the rest of the world is so
dumb compared to the weakest Cal grad that you can skim by in
life doing 35% and still do just fine. I'm on cruise control
at 70% and doing really well. The bell curve in life is much
different than the bell curve at Cal. The fact that almost
every Prof and TA will happily treat you like shit doesn't help
students either. Screw Cal, join life, win big.
\_ I know of 2 Cal undergrads who later got Marshall scholarships.

Marshall / Rhodes scholar), and another got a Luce scholarship.

4/21 Cute problem: You are given n bits which resulted from flipping a
biased coin n times (you don't know the bias). The problem is to come
up with an algorithm which will produce as many unbiased independent
random bits from this string as possible (on average). You have no
other sources of randomness except the input bits. One possible
algorithm would be to pair up the bits, and produce a random bit 1 if
the pair is 01, 0 if the pair is 10, and ignore the pair otherwise.
This isn't optimal on average, however. -- ilyas
\_ assume n is sufficiently large, first calculate the (biased)
expected value over the n bits. then instead of pairing up
bits, sample m bits at a time, and if there are more than
(expected value * m) bits with 1, output 1 or 0 otherwise.
slide the sample "window" down and continue.
\_ How do you sample without any additional randomness?
-- ilyas
\_ a simple example of the sampling logic is to take
bits 0~m, then 1~m+1, 2~m+2, etc. this does not
require added randomness. a more sophisticated
variation would vary the next sample depending
on the previous 0 or 1 output (unbiased).
\_ The problem is if you use more than $n/m$ windows
the resulting bits will not be independent anymore,
yes? -- ilyas
\_ yes for the simple logic. what do i win for
spelling out a more sophisticated logic?
\_ 1 mid sized cupie doll.
\_ eh? expected value?
\_ I am interpreting "on average" here to be, "it doesn't have to
be perfect, but come up with something good".
\_ I think "optimal on average" has to mean something like it
produces more bits (on average) than any other such algorithm
that also works over the full range of possible biases. I don't
see how it could be optimal for each possible bias (e.g. to
be optimal in the case where there is no bias, it would have
to output n bits for any input, but this would obviously not
work if there is bias). - Johnny Von Neumann
\_ With all due respect Mr. von Neumann, if the bias is 1,
no algorithm will output any random bits at all. You simply
have no randomness to work with in that case. To put it
another way, the 'optimal' number of bits you should get on
average isn't fixed, but depends on the bias. The metaphor
here is 'refining oil'. The 'tainted' randomness you get as
input is like crude oil. The 'unbiased' randomness you
get at the output is like refined oil you get after processing
the crude. The amount of stuff that comes out depends on how
much crude you have to work with, and how 'crude' it is.
-- ilyas
\_ With all due respect, you don't seem to have understood
what I wrote. An algorithm can't be optimal for the
_unbiased_ case (in which case it would have to have
no waste product) and also work in other cases, unless
you could distinguish this case in advance.
\_ I can see why you would think so, but surprisingly,
it can. -- ilyas
\_ I think ilyas means "optimal" in the sense that a
competing algorithm would produce less random bits
over the entire space of possible input strings. The
"optimal" algorithm is the one most successful at
producing the most random bits over the entire space of
input strings, relative to all other lame algorithms
that produce not as many random bits. Algorithms which
produce ANY non-random bits are super-lame and do not
qualify for consideration at all.
\_ Yes, this is what I think he means, too, and is
pretty much what I said above. He seems to be
claiming something stronger, which I still think
is impossible, but perhaps I have a blind spot. My
intuition is that you can do about twice as well
as the simple algorithm above.
\_ Interpret it as "the expected number of random bits produced by
the algorithm, given the input distribution determined by the
unknown bias must be as high as possible." I mean "on average"
precisely. It's good to think about why is it that the algorithm
isn't caring what the input distribution is, essentially.
-- ilyas
\_ How about something like this:
Suppose you saw k heads out of n flips.
Lexicographically order all n-choose-k
sequences of n flips that have k heads,
find the index i of the actual sequence
of observed flips amongst these n-choose-k
possibilities, and take the binary expansion
of i. This requires some fiddling when
n-choose-k isn't a power of two, though ---
maybe leaving out the last bit in i in this case.
\_ This is one correct algorithm, well done. This is called
a 'codebook based on the method of types', I think.
Another algorithm: run the string through gzip.
This algorithm and yours work for the same reason.
In both cases you get n*H(p) unbiased random bits out,
(which is the optimal number),
where p is the unknown bias, and H is the entropy. The
reason we don't care about the actual value of p is
because the algorithms in question are 'universal source
coding algorithms'. This is why people use gzip on just
any old file, and expect it to work well. Mr. von
Neumann's contemporary by name of Claude Shannon worked
all this out in a famous paper. -- ilyas
\_ What does "n-choose-k sequences" mean?
\_ It's a function often used in combinatorics. You can
google for its definition, and you can ask google to
compute it for you (e.g. "10 choose 5"). -- ilyas
\_ I'd get a better coin. It sounds like someone shaved yours. |

4/21 This administration stole $700mm from Afghan budget to attack Iraq.
The public needs to know about this. Email Hiatt@washpost.com
Tell him to cover the story, and tell him it's front page material.
\_ I don't think this is true, because it would indicate this
Administration has a clue.
\_ they stole the election, stole from SS and medicare...hmmmmmmm,
sounds like a pattern, but not enough care. So bizness as usual. |
