Remember, we moved to 2nd Wednesday of the month, so I'll see you guys NEXT
week at, say, Macht's Gute?

That said, if anyone was mis-scheduled and is dying to get out tonight, drop me
a line and I will help you drink a pitcher. ;)

See you tomorrow.
 
I will probably get sloppy and tell you all how much I hate dealing with UTF-8

Anyone know if there is a way to retrieve the amount of memory a variable  
is using from within Perl?

Devel::Size is pretty good.

What I need to do is fill memory, a little at a time. Im trying to force  
OOM errors. Whith the following Perl exits w/ Out of memory, but no OOM  
kills. Any ideas?

This is what Im using. I also have ulimit set to unlimited. It looks like  
Perl is doing the right thing, by just die-ing. Is there anyway to force it  
do the wrong thing?

#!/usr/bin/perl

use strict;
use warnings;
use Devel::Size qw(size);

my @mem;

while (1)
{
{
open my $contents, "test.256MB" or
die "Unable to open test.256MB: $!\n";
while ( <$contents> )
{
push @mem, $_;
}
}
my $size = size(\@mem);
print "Size = $size \n";
}

No idea.  The Linux kernel's "kill random stuff when memory is low" behavior is
voodooriffic and, as far as I know, hard to trigger.  I have not done any
research just now, though, so I could just be living under the cloud of FUD.
Let me know if you find a good strategy.

Voodoo is a good word.

This is far from perfect, there has to be a better way - but Im going to  
use this for now:

So you ned to find a sweet spot where you dont get Perl 'Out of Memory!'  
conditions. It was 11 for me.

So I just keep running

./memeater 11 &

over and over until I get OOM kills. Now I just need to do some tuning.

#!/usr/bin/perl

use strict;
use warnings;
use threads;
#use Devel::Size qw(size);
my $mem;
my $iterations = $ARGV[0] || 5;
my $count = 0 ;

while ($count < $iterations)
{
my $thr = threads->new(\&fillmeup);
#my $size = size($thr);
#print "Size = $size \n";
$count++;
}

sleep 900;

sub fillmeup
{
my $buf = 'A' x ( 1024*1024*256 );
return 0;
}

Subject: [ABE.pm] rjbs advent calendar!
Message-ID: <20091126001049.GA11762@cancer.codesimply.com>


>From my blog:

  Back when I first started learning Perl 5, I was excited to find the [Perl
  Advent Calendar](http://perladvent.pm.org/archives.html).  It was a series of
  24 or so short articles about useful Perl modules or techniques, with one new
  entry each day leading up to Christmas.  A few years later, the Catalyst crew
  started the [Catalyst Advent
  Calendar](http://www.catalystframework.org/calendar/2005).  I always liked
  the Perl Advent Calendars, and kept meaning to contribute.  Every time,
  though there were too many things I'd want to write about -- and mostly they
  were my own code, so I felt sort of smarmy and self-promoting and never did
  it.

  Finally, though, I'm glad to say I have tackled those feelings.  I will not
  shy away from showing off my own code, and I will not worry about having to
  choose just one thing.  This year, I will publish the [RJBS Advent
  Calendar](http://advent.rjbs.manxome.org/), 24+ full days of cool, useful, or
  stupid code that I have written and given as a gift to the rest of the CPAN
  community.

  I've had a lot of fun working on this project, and it's helped me find and
  fix a number of little bugs or imperfections in the software I'll be talking
  about.

  The first door opens in six days.  I hope it's as fun to read as it was to
  write.  No returns will be accepted.  Approximate actual cash value: $0.02

Basically: starting Dec 1, I'm publishing 24-ish short articles about some of
CPAN modules.  Hopefully some of them will be useful!
