Ok, I have been working in the IP Security world for the last 5-6 years, the last 4 in development of VPN and firewall protocols. I have been using Perl for test automation for the last 3-4 months and quite like the language and the community.
IMHO the best things about Perl are CPAN, O'Reilly, and Lincoln D. Stein!
If you are looking to learn Perl beyong the syntax described in the Camel book, get "Network Programming with Perl" and read it! It has taught me more about Perl than everything else but practice.
use strict ;
Since coming to the Monastary and participating it amazes me how many questions get answered with those 2 lines of code. Before I came here -w was part of my standard boilerplate and use strict was there if I remembered. Since then use strict has become part of my boilerplate. If you don't have a boilerplate, make one and use it. For a sample boilerplate, see my scratchpad and for a program that makes dynamic boilerplates, see makeperl.pl.
