Then you are an ignorant. 4% error is not important unless the difference
between the candidates is below that. When money is scarce in a county,
this is usually spent where it's needed the most, in the schools, police
and public works. The federal and states should pay for the voting system
not the poor local system.

There is fraud across the board but most of it is done by the ones who
can afford it the most. What about those thousands of New Yorkers who
voted both in New York and Florida? A large portion of absentee ballots
were cast by republicans. If you remove all the illegal absentee ballots
Al Gore wins big even with the screw up in the largely democratic counties.

Those chads should have been removed from the ballots in the first place.
If not punched there is no way in hell one of those chads can come off.
You obviously have never seen one of those ballots.

I have RH 7 and am trying to start up with vi command-line editing.
Before making any changes, echo $SHELLOPTS shows the following:
braceexpand:hashall:histexpand:monitor:history:interactive-comments:emac
s
I edited .bash_profile and added "set -o vi" (without quotes).
After logging out and back in, echo $SHELLOPTS shows:
braceexpand:hashall:histexpand:monitor:interactive-comments:vi
As you can see, I lost history. Why?
Then I added another line to .bash_profile: "set -o history".
Now echo $SHELLOPTS shows the following:
braceexpand:hashall:histexpand:monitor:history:interactive-comments:vi
This is what I expected. However, my up-arrow key no longer
displays prior commands in my history file even though the
history command works as usual. Why? What am I doing wrong?
Finally, does RH 7.0 support searching command history like
esc-p operates in tcsh?

Hello,
I upgraded from 2.2.16 to 2.4.0 and was left with can't load module errors
or directory not found errors, so I tried to trick linux by renaming the
directory from /lib/modules/2.2.16 to /lib/modules/2.4.0, but it figured out
i did that and gave me a page worth of errors at startup. How can fix that?
Where can I get the appropriate files for that directory?
Thanks

I answered another post about 9 Jan., about someone having this
problem with the junkbuster proxy. I said that it also happened
to me, that I had a real struggle dumping the directory, but
unfortunately couldn't remember how I did it exactly. I know
what you me about this breaking rm and ls.
Somebody posted this possiblity:
====
My favorite method of deleting all entries in a directory (when
the
number of entries is very large) is
tar cfv /dev/null /path/of/directory/to/empty --remove-files >
/dev/null
and then just rmdir the directory if required....

Note that I haven't tried this myself, so I don't know if it
actually works.

I don't care...as long as shit-heads are prevented from voting, I really
don't care how many are produced.

Like I said, I used bash2 as my default shell with 6.2 from the time it

somewhere that is incompatible, but I never hit if there is.

Subject: increasing open file limit
Date: Mon, 29 Jan 2001 02:56:09 GMT
We are working with Linux and have hit a snag. We are performing some
tests and require our application to open a few thousand files at a
time. (We are looking to open approx. 4096.) By inspecting ulimit we
have found that the hard-limit seems to be 1024 file descriptors per
user:
core file size (blocks) 1000000
data seg size (kbytes) unlimited
file size (blocks) unlimited
max memory size (kbytes) unlimited
stack size (kbytes) 8192
cpu time (seconds) unlimited
max user processes 256
pipe size (512 bytes) 8
open files 1024
virtual memory (kbytes) 2105343
The limit specified by /usr/src/linux/include/linux/limits.h per process
is:
#define OPEN_MAX 256 /* # open files a process may have */
We need to increase this limit from 256 per process to 4096 (or even
higher) for testing purposes. How can this be done? I assume I can do a
kernel recompile, but I would rather just flip a switch somewhere in a
configuration file, /proc, or something similar if possible.

What part of "1 part in 1,000,000 accuracy is required for ballot machine
certification"

^^^^^^^^^^^^^^^^^^^^^^
Another LAME EXCUSE RED HERRING
Give me a fucking break. For the price of one deputy sherrif's salary, you
can purchase DOZENS of Scantron (hand-MARKED, not punched) machines.
By the way, these ballot-counting machines cost no more than punch-card
tabulators...AND scantron ballots are cheaper to produce than punched cards.
This has NOTHING to do with money, and EVERYTHING to do with deliberately
selecting systems which make vote-tampering easy.
By the way....since when is West Palm Beach a "poor" county?

Translation:
Democrats are toooooooo fucking stupid to follow the directions posted
in the ballot booth AND in BIG HUGE FUCKING LETTERS at the polling place.
Probably because Democrats habitually ignore rules and laws.
Well....it's come back to haunt you.
Deal with it.

Thanks for the update. I've thrown some more handling of special cases
