perl -e "print $^X"

Hi guys, just wanna share some basic information  to camera users should know if they choose shoot setting manually. Aperture, Shutter Speed and ISO is very common term in SLR, above is the example of ideal value for each setting   this is sample combination for aperture (f-stops) and shutter speed. let's try it out..

In every aperture value we can get different kind of photo, but what is actually we looking for? it't depend on what we need. Below is a diagram illustrated subject focus in different aperture value.  as what we know, every lens have their own function, but we need to know the limitation too, below is the type of lenses with focal length size. did we know how much our camera can see?

http://perl5maven.com/perl-tutorial Perl, is a general programming language. It has been used in everything from bioscience ( http://www.bioperl.org ) to web development ( http://mojolicio.us  , http://perldancer.org ,  http://www.catalystframework.org  , and many many more.) As with many things in Perl there is usually more then one way to do things. Here is a small sample of things Perl community in general has: Parsers:  http://www.jeffreykegler.com/marpa BioPerl:  http://www.bioperl.org Scientific computing:  http://pdl.perl.org/ Webframe works: (lots here, just naming a few) * Plack:  http://plackperl.org/ * Mojolicious:  http://mojolicio.us * Perl Dancer:  http://perldancer.org * Catalyst:  http://www.catalystframework.org * CGI Application : http://search.cpan.org/~markstos/CGI-Application-3.21/lib/CGI/Application.pm Templating Frameworks: (Lot here, just naming a few) * Template Toolkit :  http://temp...

" Perl was originally written to manipulate text in files, extract data from files, and write reports, but through continued development, it can manipulate processes, perform networking tasks, process Web pages, talk to databases, and analyze scientific data."  "Perl makes simple tasks easy, and makes difficult tasks possible."  1) Perl using a scalar, but no boolean / integer / long / float / double / scring. 2) Perl inherits / extends features of many shell scripting languages: shell / korn shell / C shell / Born shell 3) there are above 25k open source modules on the CPAN site one of the greatest advantages of Perl is the wealth of modules that can be found on CPAN.
