I was introduced to the monastry by [physi]. He was my boss in a project.

I picked my name from [google://Skeeve Myth Inc|Robert Asprin's books about M.Y.T.H. Inc.] which I really love.

Things I might need (again) in the future:<ul>
<li>IP v4 address manipulations
<code>
#!/usr/bin/perl
use strict;
use warnings;
use Socket;
my $ifconfig='/usr/sbin/ifconfig';
# run ifconfig -a
open my $if, '-|', "$ifconfig -a" or die "Couldn't run $ifconfig: $!\n";
while (<$if>) {
# find a line with "broadcast" in it
# on Solaris this contains all the information I need
next unless /inet\s+(.*?)\s+netmask\s+(.*?)\s+broadcast\s+(.*?)\s*$/;
# keep ip address as it is (a dotted string)
my $iaddr= $1;
# convert the netmask to a "long"
my $netmsk= hex "0x$2";
# dito for the broadcast
my $brdcst= unpack 'N', inet_aton $3;
# How many bits does the netmask have?
my $bits= 31-int(log(0xffffffff ^ $netmsk)/log(2));
# Convert the netmask to a "slashed" IP
my $network= inet_ntoa(pack "N", ($brdcst & $netmsk)) . "/" . $bits;
# show all info found
print "$iaddr\t$network\n";
}
close $if;
</code>
</li>
<li>Reverse DNS Lookup<br>
<code>
use Socket;
my ($name,$aliases,$addrtype,$length,@addrs) = gethostbyaddr(inet_aton("74.125.79.94"));
print $name,$/;
</code>
</li>
<li>Building perl on Solaris with gcc
<ul>
<li>make sure /usr/ccs/bin is <b>not</b> in the path
</li>
<li>make sure make is in the path for "make test" e.g. by <code>
ln -s /usr/ccs/bin/make /usr/local/bin
</code>
</li>
</ul>
</li>
<li>Building perl DBI (on Solaris) with gcc
<code>
perl Makefile.PL CC=gcc LD=gcc CCCDLFLAGS=-fPIC OPTIMIZE=-O3
</code>
This is not necessary if you build your own perl as above in which case the normal process will work.
</li>
<li>Building DBD::mySQL ...<br>
make sure .../mysql/bin is in your path
</li>
<li>CSV splitting without modules<br>
<code>
sub csvsplit {
my (@result);
for ($_[0]) {
s/[\015\012]+$//;
while (s/^"((?:[^"\\]|\\.)*)"// || s/^'((?:[^'\\]|\\.)*)'// || s/^([^,]*)//) {
push(@result, $1);
last unless s/^,//;
}
}
return @result;
}</code>
</li>
