PPM problem.

2004-10-17 Thread Sara
I am trying to install DBI module for my perl installation on XP machine.
Everything was working fine, I installed a lot of modules before using the
same PPM, but now it has started giving this error (as shown below).

I have searched, but failed to find anything. I installed a fresh version of
Perl, but it's still the same.

Any ideas?

Executing pdflatex via CGI script

2004-10-17 Thread Jan Eden
Hi,

I wrote a script which takes some info from the user and generates a form letter.

The script is run locally for five users, so security is not that important (although 
it is always important, I know).

The script manages to write data to my output file if I created it first and chmodded 
it to 666, but fails otherwise.

This is because the script is run by the web user, of course. Is there a more or less 
secure way to allow the script to

a) create / write to a file
b) apply pdflatex to that file (i.e. create a pdf file from the .tex source)
c) open the resulting pdf file (using the open function in OS X)

I read that setiud scripts are considered a security hole, and though my environment 
is not that critical, I do not want to use hazardous techniques.

Any hints? Thank you.

- Jan

You can give the directory in which the file will be located 0777
permissions. Once the file has been created by the script, you can
change the directory permissions to e.g. 0755.
c) open the resulting pdf file (using the open function in OS X)
To allow somebody but the web server to open a script created file for
reading, have the script give it 0644 permissions.
It sounds as if you need to read up on the Unix/Linux permissions system.

Set Group ID Directories?
Um, allow the pdflatex to run as the web userid?
Maybe just make a CGI writable directory?

Put the correct WWW userid in the right pdflatex group?

Re: IO::Socket - i can't get it to read the data

2004-10-17 Thread Peter Scott
In article [EMAIL PROTECTED],
 [EMAIL PROTECTED] (Jeff 'japhy' Pinyan) writes:
The problem is that your data ends in \r\n, and the \r is a carriage
return.  If you print jeff\rABC, you'd *see* ABCf, because the \r
causes the cursor to go to the beginning of the line, thus overwriting
previous letters.  In your case, apparently the IP address is longer than
both the username and the password, so the IP is all you're seeing.

And just so the original poster knows *why* they're getting a \r,
the reason is that the standard for line-oriented socket protocols
is to terminate lines with \r\n.  At least, what \r\n is on Unix-type
systems (\015\012); Perl changes the value of \n on some other platforms.
This is why Socket.pm exports upon request the symbol $CRLF, which is
the proper line terminator regardless.

Learn about references; there is another argument allowed for the

use Getopt::Std;
my %opt;
getopts('abcde', \%opt);

Now run that with some options and inspect the hash %opt after the

Not only possible, I consider it mandatory :-)

Counting gaps in sequence data revisited.

2004-10-17 Thread Michael S. Robeson II
I just wanted to thank everyone for their help and suggestions. This is 
the final full working code to count continuos gaps in a every sequence 
in a multi-sequence FASTA file. It may not be elegant but it is fast 
and works well. Sorry for the long post but I wanted to share this with 
those that do any DNA work. :-)

I show in order: the format of the input data, the output of the input 
data, and finally the working script. I have yet to add comments into 
the code but I am sure many of you veterans will figure it out.

-Thanks again all! As always comments, questions or suggestions are 
welcome!

Is it best to store in a array and then join???

To actually remove *all* whitespace, you can simply do:

$word =~ s/\s+//g;
$word =~ s/,,/,NEW,/gc;

after removing the blanks ,if there are any ,, i would like to
insert a NEW word there.

So my regex, does this but its doing it partially.

word=DetailDesignActivityIncluded,NEW,,NEW,,-1,0,hello,ajey#
^^^  ^^^
These two are again not matched. I checked the options for

 c   Do not reset search position on a failed match when /g is in 
effect.
 g   Match globally, i.e., find all occurrences.
 i   Do case-insensitive pattern matching.
 m   Treat string as multiple lines.
 o   Compile pattern only once.
 s   Treat string as single line.
 x   Use extended regular expressions.

But, this is little confusing to me.

I know its greedy approach while matching patterns,but here
its missing something.

Where am i wrong?? My aim to have a NEW inserted btwn every ,,

RE: time manipulation

2004-10-17 Thread John Bruin
I performed a similar process using 2 modules:

Date::Parse (to convert date strings to unix seconds)

POSIX (strftime function) and Perls standard localtime function to convert
back from unix seconds to a formatted date string

POSIX is a standard module so your system probably already has it.
