Ladies and gentlemen, you are about to hear a very frightening
speech.  This speech is an explanation of the plans now being laid to
throw the United States into a third world war.

A CHRISTIAN VIEW OF THE HOLOCAUST

Ladies and gentlemen, you are about to hear a very frightening
speech.  This speech is an explanation of the plans now being laid to
throw the United States into a third world war.  It was made a short
time ago before a large group in the Congressional `Room of the
Willard Hotel in Washington, D.C.  Both the speech and the question
and answer period later so electrified the audience that a group of
patriots has transferred it to two long-playing records which you may
buy to play for friends, clubs, and your church group in your
community. The speaker is Mr. Benjamin Freedman, noted authority on
Zionism and all of its schemes. Mr. Freedman is a former Jew, and I
mean a FORMER Jew.  He has fought the Communist world conspiracy tooth
and nail, and stands today as a leading American patriot. We now take
you to the speaker's platform to present Benjamin Freedman.

(applause)

[Freedman's speech]

 What I intend to tell you tonight is something that you have
never been able to learn from any other source, and what I tell you
now concerns not only you, but your children and the survival of this
country and Christianity.  I'm not here just to dish up a few facts to
send up your blood pressure, but I'm here to tell you things that will
help you preserve what you consider the most sacred things in the
world:  the liberty, and the freedom, and the right to live as
Christians, where you have a little dignity, and a little right to
pursue the things that your conscience tells you are the right things,
as Christians.

   Now, first of all, I'd like to tell you that on August 25th 1960 --
that was shortly before elections -- Senator Kennedy, who is now the
President of the United States, went to New York, and delivered an
address to the Zionist Organization of America.   In that address, to
reduce it to its briefest form, he stated that he would use the armed
forces of the United States to preserve the existence of the regime
set up in Palestine by the Zionists who are now in occupation of that
area.

  In other words, Christian boys are going to be yanked out of their
homes, away from their families, and sent abroad to fight in Palestine
against the Christian and Moslem Arabs who merely want to return to
their homes. And these Christian boys are going to be asked to shoot
to kill these innocent [Arab Palestinians] people who only want to
follow out fifteen resolutions passed by the United Nations in the
last twelve years calling upon the Zionists to allow these people to
return to their homes.

 Now, when United States troops appear in the Middle East to fight
with the Zionists as their allies to prevent the return of these
people who were evicted from their homes in the 1948 armed
insurrection by the Zionists who were transplanted there from Eastern
Europe... when that happens, the United States will trigger World War
III.

 You say, when will that take place?  The answer is, as soon as
the difficulty between France and Algeria has been settled, that will
take place.  As soon as France and Algeria have been settled, that
will take place. As soon as France and Algeria have settled their
difficulty, and the Arab world, or the Moslem world, has no more war
on their hands with France, they are going to move these people back
into their homes, and when they do that and President kennedy sends
your sons to fight over there to help the crooks hold on to what they
stole from innocent men, women and children, we will trigger World War
III; and when that starts you can be sure we cannot emerge from that
war a victor. We are going to lose that war because there is not one
nation in the world that will let one of their sons fight with us for
such a cause.

 I know and speak to these ambassadors in Washington and the
United Nations -- and of the ninety-nine nations there, I've consulted
with maybe seventy of them -- and when we go to war in Palestine to
help the thieves retain possession of what they have stolen from these
innocent people we're not going to have a man there to fight with us
as our ally.

   And who will these people have supporting them, you ask.  Well,
four days after President Kennedy -- or he was then Senator Kennedy --
made that statement on August 28, 1960, the Arab nations called a
meeting in Lebanon and there they decided to resurrect, or reactivate,
the government of Palestine, which has been dormant more or less,
since the 1948 armed insurrection by the Zionists.

 Not only that... they ordered the creation of the Palestine Army,
and they are now drilling maybe a half a million soldiers in that area
of the world to lead these people back to their  homeland.  With them,
they have as their allies all the nations of what is termed the
Bandung Conference Group.  That includes t

The eastern European Jews, who form 92 per cent of the world's population of those people who call themselves Jews, were originally Khazars.

[small Pox]

The eastern European Jews, who form 92 per cent of the world's
population of those people who call themselves Jews, were originally
Khazars.

Now, what are the facts about the Jews?

 The Jews -- I call them Jews to you, because they are known as
Jews. I don't call them Jews.  I refer to them as so-called Jews,
because I know what they are.  If Jesus was a Jew, there isn't a Jew
in the world today, and if those people are Jews, certainly our Lord
and Savior was not one of them, and I can prove that.

 Now what happened?  The eastern European Jews, who form 92 per
cent of the world's population of those people who call themselves
Jews, were originally Khazars.

 They were a warlike tribe that lived deep in the heart of Asia.
And they were so warlike that even the Asiatics drove them out of Asia
into eastern Europe -- and to reduce this so you don't get too
confused about the history of Eastern Europe -- they set up this big
Khazar kingdom: 800,000 square miles.  Only, there was no Russia,
there were no other countries, and the Khazar kingdom was the biggest
country in all Europe -- so big and so powerful that when the other
monarchs wanted to go to war, the Khazars would lend them 40,000
soldiers. That's how big and powerful they were.

  Now, they were phallic worshippers, which is filthy.  I don't
want to go into the details of that now.  It was their religion the
way it was the religion of many other Pagans or Barbarians elsewhere
in the world.

 Now, the [Khazar] king became so disgusted with the degeneracy of
his kingdom that he decided to adopt a so-called monotheistic faith --
either  Christianity, Islam -- the Moslem faith -- or what is known
today as Judaism -- really Talmudism.  So, like spinning a top and
calling out "eeny, meeny, miney, moe,"  he picked out so-called
Judaism.  And that became the state religion.

 He sent down to the Talmudic schools of Pumbedita and Sura and
brought up thousands of these rabbis with their teachings, and opened
up synagogues and schools in his kingdom of 800,000 people -- 800,000
thousand square miles -- and maybe ten to twenty million people; and
they became what we call Jews.  There wasn't one of them that had an
ancestor that ever put a toe in the Holy Land, not only in Old
Testament history, but back to the beginning of time.  Not one of
them!  And yet they come to the Christians and they ask us to support
their armed insurrection in Palestine by saying:

"Well, you want to certainly help repatriate God's  chosen people
to their Promised Land, their ancestral homeland,  It's your Christian
duty.  We gave you one of our boys as your Lord and Savior.  You now
go to church on Sunday, and kneel and you worship a Jew, and we're
Jews."

 Well, they were pagan Khazars who were converted just the same as
the Irish [were converted].  And it's just as ridiculous to call them
"people of the Holy Land," as it would be. . . there are 54 million
Chinese Moslems.  Fifty four million!  And, Mohammed only died in 620
A.D., so in that time, 54 million Chinese have accepted Islam as their
religious belief.

 Now imagine, in China, 2,000 miles away from Arabia, where the
city of Mecca is located, where Mohammed was born. . . imagine if the
54 million Chinese called themselves  'Arabs'.  Imagine! Why, you'd
say they're lunatics.  Anyone who believes that those 54 million
Chinese are Arabs must be crazy.  All they did was adopt as a
religious faith; a belief that had its origin in Mecca, in Arabia.

  The same as the Irish.  When the Irish became Christians, nobody
dumped them in the ocean and imported from the Holy Land a new crop of
inhabitants that were Christians. They weren't different people.  They
were the same people, but they had accepted Christianity as a
religious faith.

 Now, these Pagans, these Asiatics, these Turko-Finns. . . they
were a Mongoloid race who were forced out of Asia into eastern
Europe.  They likewise, because their king took the faith -- Talmudic
faith -- they had no choice.  Just the same as in Spain:  If the king
was Catholic, everybody had to be a Catholic.  If not, you had to get
out of Spain.  So everybody -- they lived on the land just like the
trees and the bushes; a human being belonged to the land under their
feudal system -- so they [Khazars] all became what we call today,
Jews!

  Now imagine how silly it was for the Christians. . . for the
great Christian countries of the world to say, "We're going to use our
power, our prestige to repatriate God's chosen people to their
ancestral homeland, their Promised Land."

 Now, could there be a bigger lie than that?  Could there be a
bigger lie than that?

 And because they control the newspapers, the magazines, the
radio, the television, the book publishing business, they have the
ministers in the pulpit, they have the politicians on the soap boxes
talking the same language . . . so naturally you'd believe black is
white if you heard it ofte

SCHOLARLY TESTIMONIAL VIDEO : Joseph Moshe (MOSSAD Microbiologist) Swine flu vaccine 1

[small Pox]

Joseph Moshe (MOSSAD Microbiologist) Swine flu vaccine 1
http://www.youtube.com/watch?v=9ranNpzlXIo

Part 1 Today, the MSM are not talking about this case any more.
Yesterday, they wanted us to believe that Joseph Moshe was a nutcase
and a terrorist, arrested for threatening to bomb the White House.
Interesting detail about his arrest (the Westwood standoff) was that
he seemed to be immune to the 5 cans of tear gas and 5 gallons of law-
enforcement grade pepper spray they pumped into his face. He very
calmly remained in his car, as the video footage of his arrest shows.


Professor Moshe had called into a live radio show by Dr. A. True Ott,
(explanation of Joseph Moshes call at 06:00) broadcast on Republic
Broadcasting claiming to be a microbiologist who wanted to supply
evidence to a States Attorney regarding tainted H1N1 Swine flu
vaccines being produced by Baxter BioPharma Solutions. He said that
Baxters Ukrainian lab was in fact producing a bioweapon disguised as a
vaccine. He claimed that the vaccine contained an adjuvant (additive)
designed to weaken the immune system, and replicated RNA from the
virus responsible for the 1918 pandemic Spanish flu, causing global
sickness and mass death.

Joseph Moshe was soon after his arrest sent or let go to Israel.
Nothing has been heard from him since. The Secret Service was not the
agency involved in the surveillance of Moshe at his home in
California. This was done by the FBI, who had orders to detain or
arrest him. Mounted on top of a large black vehicle used in his arrest
was a microwave weapon that possibly damaged the electronics in Moshes
car as well as any communication devices he had which might have been
used to contact the media or others who could help him.
Baxter Pharmaceutical has been caught, red-handed, in spreading a
live, genetically engineered H5N1 Bird flu vaccine as a lethal
biological weapon all over the world, destined to be used for human
vaccinations. This happened just a few months ago.

Baxter International Inc. had mixed live, genetically engineered avian
flue viruses in vaccine material shipped to 18 countries.

Baxter knew full well that their vaccine was lethal, because the year
before they had tested it on a few hundred homeless Polish people
dozens died as a result.

Qui bono? We think it may be profit-motivated, but for the conspiracy-
minded: The latter complaint alludes to intentional culling of the
herd. Have you heard of the Georgia Guidestones? An enormous monument
loaded with Masonic symbolism costing millions of dollars, it has been
erected by unknown, powerful elites (multimillionaires with the clout
to erect monuments wherever they please, obviously) around 30 years
ago. It gives an alternative ten commandments, of which the first is
the extermination of six and a half billion people from the face of
the Earth. Half a billion will remain. This is the number of people
the planet can sustain indefinitely, so that the descendents of the
Rothschilds and Rockefellers can live in peace and affluence
indefinitely. Slaves are needed to produce that luxury, but 500
million will do just fine. But how does one go about killing off most
of the world?

Vaccinating the planet with a bioweapon with near-100% mortality would
do the trick. Baxter would provide both the bioweapon as well as the
vaccine against it to civilized Western peoples. Result: We can
plunder Africa, we have no more competition from SE Asia, the oil is
for our taking and only Western and perhaps Chinese sheeple remain.

Rockefeller said this in 1994 at a U.N. dinner: We are on the verge of
a global transformation. All we need is the right major crisis, and
the nations will accept the New World Order. PNAC said something
similar right before 9/11.

A Spanish Doctor in Internal Medicine largely agrees with the above

http://users.rcn.com/python/download/Descriptor.htm#descriptor-protocol

descr.__get__(self, obj, type=None) --> value

descr.__set__(self, obj, value) --> None

descr.__delete__(self, obj) --> None

These methods are passed the object they're operating on. If the name is
in any way important, which is almost certainly is not, it can either be
passed in to the constructor of the descriptor or determined by
introspection.

loading configuration files that are themselves python

[Matthew Vernon]

Hi,

Is there a more idiomatic way of loading in a configuration file
that's python code than:

_temp=__import__(path,fromlist='cachestrs')
cachestrs=_temp.cachestrs

? I mean, that's pretty ugly...Plain "import" doesn't work in this
case because 'path' is a variable defined elsewhere

TIA,

Matthew

execfile(path) 

in a module with a fixed name that you can import wherever you need access 
to your configuration data?

At least you have a way to do it, so you should be happy !-)

Another solution would be to add the path to sys.path, but it wouldn't
necessarily be the best thing to do here.

While it would have been technically possible, I fail to imagine any use

OK, I'll give you that.  It is on the backbone of the net at 151 Front
Street in Toronto, has almost 100% uptime and uses high speed servers
but we don't have 15 layers of bureaucracy between the owner and the
user and I certainly know of no "real" hosting provider that invites
all their clients out for dinner once a year.  And how can we be a real

I know what being "major" means to the owners and stockholders but what

Hold on.  That *is* the generated list and Python 3.1 is on it.  We
have both 2.6 and 3.1.  The 3.1 version is listed right below the 2.6
one.  The page is generated from pkg_info(1) and includes everything we
have installed from FreeBSD ports.

subprocess query

[Sudheer]

Hi,
 What's wrong with the following code. The program waits indefenitely
at  'output = p2.stdout.read()'


from subprocess import *

p1=Popen(['tr', 'a-z', 'A-Z'],stdin=PIPE,stdout=PIPE)
p2=Popen(['tr','A-Z', 'a-z'],stdin=p1.stdout,stdout=PIPE)
p1.stdin.write("hello")
p1.stdin.close()

output = p2.stdout.read()

print output

Try using .communicate() instead of reading and writing to .stdin and .stdout.
Adding a newline (i.e. "hello\n") may also help.

My extension code generator for C++

[Rouslan Korneychuk]

It's still in the rough, but I wanted to give an update on my C++ 
extension generator. It's available at http://github.com/Rouslan/PyExpose


The documentation is a little slim right now but there is a 
comprehensive set of examples in test/test_kompile.py (replace the k 
with a c. For some reason, if I post this message with the correct name, 
it doesn't show up). The program takes an input file like


 
 
 module doc string

 
 class doc string
 
 
 
 
 return-semantic="copy"/>

 
 
 

and generates the code for a Python extension.

The goal has been to generate code with zero overhead. In other words I 
wanted to eliminate the tedium of creating an extension without 
sacrificing anything. In addition to generating a code file, the 
previous input would result in a header file with the following:


extern PyTypeObject obj_DVectorType;
inline PyTypeObject *get_obj_DVectorType() { return &obj_DVectorType; }
struct obj_DVector {
PyObject_HEAD
storage_mode mode;
std::vector > base;

PY_MEM_NEW_DELETE
obj_DVector() : base() {

PyObject_Init(reinterpret_cast(this),get_obj_DVectorType());
mode = CONTAINS;
}
obj_DVector(std::allocator const & _0) : base(_0) {

PyObject_Init(reinterpret_cast(this),get_obj_DVectorType());
mode = CONTAINS;
}
obj_DVector(long unsigned int _0,double const & 
_1,std::allocator const & _2) : base(_0,_1,_2) {


PyObject_Init(reinterpret_cast(this),get_obj_DVectorType());
mode = CONTAINS;
}
obj_DVector(std::vector > const & _0) 
: base(_0) {


PyObject_Init(reinterpret_cast(this),get_obj_DVectorType());
mode = CONTAINS;
}
};

so the object can be allocated in your own code as a single block of 
memory rather than having a PyObject contain a pointer to the exposed type.


storage_type is an enumeration, adding very little to the size of the 
Python object (or maybe nothing depending on alignment), but if you add 
new-initializes="true" to the  tag and the exposed type never 
needs to be held by a pointer/reference (as is the case when the exposed 
type is inside another class/struct), even that variable gets omitted.


The code also never uses PyArg_ParseTuple or its variants. It converts 
every argument using the appropriate PyX_FromY functions. I noticed 
PyBindGen does the following when a conversion is needed for one argument:


py_retval = Py_BuildValue((char *) "(O)", value);
if (!PyArg_ParseTuple(py_retval, (char *) "i", &self->obj->y)) {
Py_DECREF(py_retval);
return -1;
}
Py_DECREF(py_retval);

On the other hand, here's the implementation for __sequence__getitem__:

PyObject * obj_DVector___sequence__getitem__(obj_DVector 
*self,Py_ssize_t index) {

try {
std::vector > &base = 
cast_base_DVector(reinterpret_cast(self));

return PyFloat_FromDouble(base.at(py_ssize_t_to_ulong(index)));

} EXCEPT_HANDLERS(0)
}

(cast_base_DVector checks that base is initialized and gets a reference 
to it with regard to how it's stored in obj_DVector. If the class is 
new-initialized and only needs one means of storage, it's code will just 
be "return obj_DVector->base;" and should be inlined by an optimizing 
compiler.)



I'm really interested in what people think of this little project.

python app development

an anyone recommend a resource (book,tutorial,etc.) that focuses on
application development in python? something similar to Practical

(for now).

i'm in a bit of a funny place, i have a decent/good grasp of python
syntax and my logic isn't bad, but i have no clue on how to assemble
an application, i seem to be stuck on writing scripts.

i've looked at the source of a few projects but the flow is way over
my head, i understand the syntax but not the logic, which is why i'm
looking for a project-cenetered learning resource, instead of a
reference or language-feature resource. also, it seems that a lot of
app programming is 90% gui bindings, with very little actual code, or
am i totally way off mark?

i recently picked up the django practical projects book, and in a few
days i re-wrote a website i did with django. i feel it was the book's
project-centric approach that made this possible.

How does it deal with pointers? What if something returns a const
pointer - is const correctness enforced?

All in all, it looks rather neat.

I think you are referring to GUI applications. There are plenty of GUI
Libraries out there. One of my favorites is the Qt library by Nokia
(former by Trolltech) for which you can get python bindings PyQt and PySide.

http://doc.qt.nokia.com/4.7-snapshot/index.html
http://www.riverbankcomputing.co.uk
http://www.pyside.org

You might want to read through the tutorials given in the documentation
at the Nokia site and possibly take a look at the examples provided
with, e.g. PyQt.

I'm sure other will add in more valuable links and suggestions.

Best regards

If the app is a gui app and if logic is overly intermixed with gui 
stuff, I am sure it can seem like that. Many recommend the MVC 
model-view-controller model for app design. Even that can be confusing; 
to me it should be model-controller-view, even though that is harder to 
say. What are the data (values and objects) and how are they stored? 
What are the rules for manipulating the data and objects? And then, and 
only then, how to communicate with the user?


i recently picked up the django practical projects book, and in a few
days i re-wrote a website i did with django. i feel it was the book's
project-centric approach that made this possible.


Another issue is who controls the flow of interactions, the user or the 
code. For instance, a gui form used for input tends to direct the user 
along a linear path. The same form, used for edit, presents existing 
data and allows the user to pick and choose the fields to edit. This 
distinction, along with MVC ideas, is important for reading source code.


I have mostly seen this issue discussed in game reviews and game design 
writing. In computer games, there is the same general difference between 
a linear obstacle course game and a world to be explored in whatever 
order one wants. (And there are some with both an explorable world *and* 
a (somewhat optional) linear main quest line.)


I am not familiar with any general app design books, but I have seen 
game design articles and books that are on a par with writing about web 
design. There are other books on business apps.

The problem is that p2 is inheriting Python's copy of the write end of the
pipe corresponding to p1.stdin, which means that it's impossible to
generate EOF on the pipe (i.e. p1.stdin.close() is a no-op):

l-wx-- 1 user users 64 Jul  3 20:51 4 -> pipe:[31472681] <= ***

On Unix, you can add close_fds=True when creating p2, but that won't work
on Windows (it prevents redirection of stdin/stdout/stderr). OTOH, I don't
know whether the problem exists on Windows; if it doesn't just set
close_fds to True on Unix and False on Windows.

Alternatively, on Unix you should be able to use:

fcntl(fd, F_SETFD, FD_CLOEXEC)

(from the fcntl module) to prevent the write end of the pipe from being
inherited.

Worse still, killing the script with Ctrl-C will leave both of the child
processes behind.

In C, you would typically close the unused ends of the pipes within the
child half of the fork(), before the exec(), but you don't have that
degree of control with subprocess.

On Windows, you can chose whether a handle is inheritable or not, but I
don't know whether you can do that from within Python.

I have never tried swig, but as far as I understand, SWIG uses a layered 
approach where part of the extension is defined C/C++ and that is 
wrapped in Python code. Mine implements the extension completely in C++.




The documentation is a little slim right now but there is a
comprehensive set of examples in test/test_kompile.py (replace the k
with a c. For some reason, if I post this message with the correct name,
it doesn't show up). The program takes an input file like

  
  
  module doc string

  
  class doc string
  
  
  
  
  


func="operator[]" would also work, I assume?


  
  
  

and generates the code for a Python extension.

[snip]

I'm really interested in what people think of this little project.


How does it deal with pointers? What if something returns a const
pointer - is const correctness enforced?



When returning pointers or references, you either have to specify a 
conversion explicitly or use the "return-semantic" attribute. The 
current options are "copy", which dereferences the pointer and copies by 
value, and "managed-ref" which is for exposed classes, where the 
returned PyObject stores the value as a reference and holds on to a 
reference-counted pointer to the object the returned the value (there is 
also "self" which has nothing to do with returning pointers. With 
"self", the return value of the wrapped method is ignored and a pointer 
to the class is returned).


I can easily add other options for "return-semantic", such as keeping a 
pointer and deleting it upon destruction. I just implemented the ones I 
need for the thing I'm working on.


As far as returning const pointers and const correctness, I'm not sure 
exactly what you mean. If you mean is there a mechanism to hold on to 
const objects and prevent them form being modified, the answer is no. 
It's not something I need.



All in all, it looks rather neat.

Yes, you can also supply a function if the first parameter accepts the 
type being wrapped (__rop__ methods will even accept the second 
parameter taking the wrapped type).

IMAP Problems

[Paul Jefferson]

Hi,
I'm trying to write a simple script which displays the basic details
of a person's mailbox. My problem is that it causes all the messages
to be marked as read on the server, which is not what I'm after, and I also
can't get the imap.sort command to work properly (currently
commented out as I replaced it with a imap.search to get the thing
working.
These are probably very simple things, but I've not tried this library
before so am a bit stuck so any help wwould be very gratefully
received.
Thanks,
Paul

Code:

# -*- coding: cp1252 -*-
import imaplib,email

# you want to connect to a server; specify which server
server= imaplib.IMAP4_SSL('imap.googlemail.com')
# after connecting, tell the server who you are
server.login('x...
@gmail.com', 'xxx')
# this will show you a list of available folders
# possibly your Inbox is called INBOX, but check the list of mailboxes
code, mailboxen= server.list()
print mailboxen
# if it's called INBOX, then…
server.select("INBOX")

typ, data = server.search(None, 'ALL')
#typ, data = server.sort("Date","UTF-8", 'ALL')
print len(data[0].split())
for num in data[0].split():
typ, data = server.fetch(num, '(RFC822)')
#print 'Message %s\n%s\n' % (num, data[0][1])
msg = email.message_from_string(data[0][1])
print msg["From"]
print msg["Subject"]
print msg["Date"]
print "___"

Confusion over etree.ElementTree.Element.getiterator

It seems that getiterator isn't returning the tags I ask for.

I would have expected at least 2 script tags to be found, considering
iterating over the whole lot found at least 2 at the end there.

Hmm, I think I've worked it out. Apparently the XML namespace forms

Russia Watched 9/11
In Real Time On Satellite

By Jon Carlson

Your countrymen have been murdered and the more you delve into it
the more it looks as though they were murdered by our government, who
used it

as an excuse to murder other people thousands of miles away.
If you ridicule others who have sincere doubts and who know
factual information that directly contradicts the official report and
who want

explanations from those who hold the keys to our government, and have
motive, means, and opportunity to pull off a 9/11, but you are too
lazy or

fearful, or ... to check into the facts yourself, what does that make
you?

Full Statement of Lt. Col. Shelton F. Lankford, US Marine Corps (ret)
Retired U.S. Marine Corps Fighter Pilot
February 20, 2007

http://www.patriotsquestion911.com/Statement%20Lankford.html

In April, 2006, Journalist Webster Tarpley interviewed Thierry
Meyssan, President of the Voltaire Network, an organization of 20
different news

agencies in Europe, Middle East and Africa, with correspondents in
many countries. Thierry trumped America's pseudo-journalists with his
2002 book,

Pentagate, drawing first blood on the Pentagon 9/11 Hoax.

TM:. He (Gen. Ivashov) was the chief of armed forces in Russia on
9/11. He says the Russian forces were watching North America because
of the

large military exercises being carried out by the US that day, so they
saw in real time by satellite what was happening on that day.

TM: When they heard about the attacks, Pres. Putin tried to call
Bush to tell him that the Russians were not involved. He was not able
to reach

him. But they understood already that the collapse of the buildings
could not have been done by the planes. They already realized it was
controlled

demolition - an internal problem and not an external attack

WGT. How did US government, the State Dept respond to your
(Pentagate) critique?
TM. First they said I would not be allowed to go your country any
more. Then Ms. Clark of State Dept said that if any journalist talks
about my

book in the US they will not be allowed to attend press conferences at
the Pentagon. They published on their website a page trying to refute
my

book.

http://www.waronfreedom.org/tarpley/rbn/RBN-42206-Meyssan.html

In April, 2005, writer Chevalier Désireé, from France but formerly
USA, revealed that Russia watched on their satellite as the A3
Skywarrior left a

carrier and impacted the Pentagon:

It seems that it is common knowledge in these circles that Russian
satellites photographed a ship-launched craft (seems to have been a
drone

type plane rather than a missle) that ended up impacting the Pentagon
on Sept 11, 2001, and that, for various reasons this information has
been

withheld from the public.
I was naturally startled to hear this even though I have long held
the opinion that it was NOT a commercial jetliner that hit the
Pentagon. I

think the thing that startled me was the fact that, if Russia (and
perhaps other countries with satellites?) had proof that Flight 77 did
not hit

the Pentagon, why weren't they revealing this?

http://web.archive.org/web/20050728121017/http://perfectinfidel.blogspot.com/2005/04/david-beckham-and-flight-77-in-paris.html

In 2002 some US spy satellite photos from the sixties were released to
the public domain:

"It's a welcome move," said Steven Aftergood of the Project on
Government Secrecy, an effort of the Federation of American Scientists
and based

in Washington, D.C.
"First and foremost, these images are of historical interest. They
feature images of national security significance that served as an
important

input to the U.S. Government policy process. So they can help
historians shed some light on that process," Aftergood told
SPACE.com.



Considering that the Pentagon STILL hasn't released over 80 videos of
the Pentagon Hoax, release of the satellite photos of the 9/11 mass
murder is

not in the cards.

In our last installment the strong case was made that aircraft carrier
USS George Washington anchored off Long Island just a short helicopter
ride

from Manhattan served as base of operations for 9/11:

The 9/11 Base Of Operations:
Aircraft Carrier USS George Washington
http://home.att.net/~south.tower/911AirBase1.htm

Of course, a satellite image of the USS George Washington plying the
waters off Long Island during the 9/11 mass murder would be the final
nail in

the coffin.

But as a programmer, I’m not in the habit of doing “repetitive” and

How would you deal with this, then: I wrote a script called ExtractMac, to 
convert various old Macintosh-format documents accumulated over the years 
(stored in AppleDouble form by uploading to a Netatalk server) to more 
cross-platform formats. This has a table of conversion commands to use. For 
example, the entries for PICT and TEXT Macintosh file types look like this:

"PICT" :
  {
"type" : "image",
"ext" : ".png",
"act" : "convert %(src)s %(dst)s",
  },
"TEXT" :
  {
"type" : "text",
"ext" : ".txt",
"act" : "LineEndings unix <%(src)s >%(dst)s",
  },
 
The conversion code that uses this table looks like

Cmd = \
  (
Act.get("act", "cp -p %(src)s %(dst)s")
%
  {
"src" : ShellEscape(Src),
"dst" : ShellEscape(DstFileName),
  }
  )
sys.stderr.write("Doing: %s\n" % Cmd)
Status = os.system(Cmd)

How much simpler would your alternative be? I don’t think it would be 
simpler at all.

You probably want to try examine() instead of select().  That opens
the mailbox in a read-only mode which and should avoid changing any
flag values.

Lua is faster than Fortran???

[sturlamolden]

I was just looking at Debian's benchmarks. It seems LuaJIT is now (on
median) beating Intel Fortran!

C (gcc) is running the benchmarks faster by less than a factor of two.
Consider that Lua is a dynamically typed scripting language very
similar to Python.

LuaJIT also runs the benchmarks faster than Java 6 server, OCaml, and
SBCL.

I know it's "just a benchmark" but this has to count as insanely
impressive. Beating Intel Fortran with a dynamic scripting language,
how is that even possible? And what about all those arguments that
dynamic languages "have to be slow"?

If this keeps up we'll need a Python to Lua bytecode compiler very
soon. And LuaJIT 2 is rumoured to be much faster than the current...

Looking at median runtimes, here is what I got:

   gcc   1.10

   LuaJIT1.96

   Java 6 -server2.13
   Intel Fortran 2.18
   OCaml 3.41
   SBCL  3.66

   JavaScript V8 7.57

   PyPy 31.5
   CPython  64.6
   Perl 67.2
   Ruby 1.9 71.1

The only comfort for CPython is that Ruby and Perl did even worse.

By being clever, using Just In Time compilation as much as possible, and 
almost certainly using masses of memory at runtime. (The usual trade-off 
between space and time.)

See the PyPy project, which aims to do the same thing for Python as Lua 
have done. Their ultimate aim is to beat the C compiler and be faster 
than C. So far they've got a bit to go, but they're currently about twice 
as fast as CPython.


> And what about all those arguments that dynamic

They're bullshit, of course. It depends on the nature of the dynamicism. 
Some things are inherently slow, but not everything.

Fast, tight, dynamic: pick any two.


> If this keeps up we'll need a Python to Lua bytecode compiler very soon.

"Need" is a bit strong. There are plenty of applications where if your 
code takes 0.1 millisecond to run instead of 0.001, you won't even 
notice. Or applications that are limited by the speed of I/O rather than 
the CPU.

But I'm nitpicking... this is a nice result, the Lua people should be 
proud, and I certainly wouldn't say no to a faster Python :)

[...]
> The only comfort for CPython is that Ruby and Perl did even worse.

It's not like this is a race, and speed is not the only thing which a 
language is judged by. Otherwise you'd be programming in C, not Python, 
right?

Need might be too strong, sorry. I'm not a native speaker of
English :)

Don't read this as a complaint about Python being too slow. I don't
care about milliseconds either. But I do care about libraries like
Python's standard library, wxPython, NumPy, and matplotlib. And when I
need C, C++ or Fortran I know where to fint it. Nobody in the
scientific community would be sad if Python was so fast that no C or
Fortran would have to be written. And I am sure Google and many other
users of Python would not mind either. And this is kind of a proof
that it can be. Considering that Lua is to Python what C is to C++
(more or less), it means that it is possible to make Python run very
fast as well.

Yes the LuaJIT team should be proud. Making a scripting language run
faster than Fortran on CPU-bound work is a superhuman result.

How to disable readline when building Python?

[Sridhar Ratnakumar]

For licensing reasons, I need to disable readline, except editline on 
OSX, when building Python. For the life of me, I cannot figure out how 
this can be done ("./configure --help" does not show anything relevant); 
I've tried the following, and readline.so will still be built:


- ./configure --without-readline
- ./configure --disable-readline
- Set `do_readline = False` in setup.py

This is for Python 2.6; and I am yet to port the same to 2.7.

Hmm, I think I've worked it out. Apparently the XML namespace forms
part of the tag name in this case. Is that what is intended?


Sure.



I didn't see any examples of this in the docs.


Admittedly, it's three clicks away from the library docs on docs.python.org.

Re: My extension code generator for C++

The code also never uses PyArg_ParseTuple or its variants. It converts
every argument using the appropriate PyX_FromY functions. I noticed
PyBindGen does the following when a conversion is needed for one argument:

py_retval = Py_BuildValue((char *) "(O)", value);
if (!PyArg_ParseTuple(py_retval, (char *) "i", &self->obj->y)) {
Py_DECREF(py_retval);
return -1;
}
Py_DECREF(py_retval);

On the other hand, here's the implementation for __sequence__getitem__:

PyObject * obj_DVector___sequence__getitem__(obj_DVector
*self,Py_ssize_t index) {
try {
std::vector > &base =
cast_base_DVector(reinterpret_cast(self));
return PyFloat_FromDouble(base.at(py_ssize_t_to_ulong(index)));

} EXCEPT_HANDLERS(0)
}


Check the code that Cython uses for these things. It generates specialised 
type conversion code that has received a lot of careful benchmarking and 
testing on different platforms.
