Top Forums Programming To Perl or not to Perl, that is the question... ;o) Post 303037702 by Neo on Friday 9th of August 2019 08:12:06 PM

As a side note, when I was the lead guy during the once famous "Langley Cyber Attack", where my work in an epic "email reply spam battle" happened over two decades ago, long before spam filters became of age, we wrote all our email anti-spam filters and detection algorithms in PERL.

Edit: For anyone interested in the early days of "cyberwar" in the 1998/1997 timeframe:

E-Mail Bombs and Countermeasures: Cyber Attacks on Availability and Brand Integrity

That PERL code "way back when" was "very crude" by todays standards, but it was very effective and fast. PERL was the best tool for that job "way back when". I was a huge PERL advocate back then, and would write all scripts in PERL, even when PERL was not needed. I loved PERL so much back then that I tried to get everyone to learn it and use it.

Sometimes old guys like me forget that the younger generations may not have had the chance to develop code in PERL and other "out of favor" programming languages these days. But when I read this discussion it brings back wonderful memories of some of the best "tech days" of my life, defending the US Air Force against hackers with PERL scripts in real-time.

wisecracker, I say "go for it" if you or anyone reading this has the time or interest to learn PERL. I would love to see a lot of people posting PERL problems here. Perhaps that would jog even more great memories from decades ago from the deep trenches of cyber warfare battles when the web was but an infant.

YAML::XS(3pm)						User Contributed Perl Documentation					     YAML::XS(3pm)

NAME
YAML::XS - Perl YAML Serialization using XS and libyaml SYNOPSIS
use YAML::XS; my $yaml = Dump [ 1..4 ]; my $array = Load $yaml; DESCRIPTION
Kirill Siminov's "libyaml" is arguably the best YAML implementation. The C library is written precisely to the YAML 1.1 specification. It was originally bound to Python and was later bound to Ruby. This module is a Perl XS binding to libyaml which offers Perl the best YAML support to date. This module exports the functions "Dump", "Load", "DumpFile" and "LoadFile". These functions are intended to work exactly like "YAML.pm"'s corresponding functions. CONFIGURATION
$YAML::XS::UseCode $YAML::XS::DumpCode $YAML::XS::LoadCode If enabled supports deparsing and evaling of code blocks. $YAML::XS::QuoteNumericStrings When true (the default) strings that look like numbers but have not been numified will be quoted when dumping. This ensures leading that things like leading zeros and other formatting are preserved. USING YAML
::XS WITH UNICODE Handling unicode properly in Perl can be a pain. YAML::XS only deals with streams of utf8 octets. Just remember this: $perl = Load($utf8_octets); $utf8_octets = Dump($perl); There are many, many places where things can go wrong with unicode. If you are having problems, use Devel::Peek on all the possible data points. SEE ALSO
