Davids Perl Games project is a collection of ASCII graphics arcade style games written in Perl.

These games are recreations of simple ASCII graphics games originally written in BASIC.

They are ideal for use as Perl programming tutorials. Some of the first few games are PerlBlaster (defend your planet from invading aliens), PerlRacer (steer your car through the twisting passages), and PerlArena (eliminate the mutant hordes).

Perl OS is a program written in the Perl programming language combined with the Perl module Tk.

Perl OS was created to make an easy interface to run Perl/Tk programs. It was also created to be an easy working environment complete with a text editor, paint program, and more.

The program comes with several programs, along with a utility to add many more which can be found on the Internet.

From the outside, Perl OS looks like a simple operating system. But inside, it is a powerful system for working with Perl and Tk.

For more details please visit the Perl OS home page:

Business::Payroll is a series of Perl Modules that provides an API for working with multiple countries federal, state and local taxes.
Payroll Perl Modules project also supports calculating mileage reimbursement values and can handle adjustment entries.
The Business::Payroll module starts with an xml document in the Input format and if everything is successfull, outputs the results in the Output XML format.
Currently only the US is supported and MO is the only supported state. We are not supporting any cities in MO yet. Federal Income, FICA, Medicare and Mileage Rates are all being calculated. We take into account the number of allowances people can claim and the fact that you can withhold more for federal and state.
Federal Income tables are only available for any date >= 07/01/2001.
See the payroll_test.pl script and input.xml file for a sample implementation.
Use process_payroll (in the /usr/bin directory after an rpm install, otherwise in the payroll-x.y directory) to actually process payroll files for real.
process_payroll will take the specified raw xml file and process it. If no errors occured, then you get the result on stdout. If you specify 2 file names the result will go into the second file. You can specify - (for the first file) and it will know to work with stdin. I.e. you can pipe the file to be processed. Ex. cat input.xml | process_payroll - would process input.xml from the stdin and then output the result to stdout.
Enhancements:
- This release has been updated to cover the 2006 tax changes.

Digest::Perl::MD4 is a Perl implementation of Ron Rivests MD4 Algorithm.

This is not C-code interface (like Digest::MD5) but a Perl-only implementation of MD4 (like Digest::Perl::MD5). Because of this, it is slow but avoids platform specific complications. For efficiency you should use Digest::MD4 instead of this module if it is available.

SYNOPSIS

# Functional style
use Digest::Perl::MD4 qw(md4 md4_hex md4_base64);

$hash = md4 $data;
$hash = md4_hex $data;
$hash = md4_base64 $data;


# OO style
use Digest::Perl::MD4;

$ctx = Digest::Perl::MD4->new;

$ctx->add($data);
$ctx->addfile(*FILE);

$digest = $ctx->digest;
$digest = $ctx->hexdigest;
$digest = $ctx->b64digest;

For some problems, particularly in the presentation layer, thinking of the solution as a webpage that can run perl is more natural than thinking of it as a perl script that can print a webpage.

It's been done before, but this module is simple. The source code is compact: one file and less than 2k of code. Simply put: if you can do it in Perl, you can do it in Markup:Perl, only without all the print statements, heredocs and quotation marks.

Requirements:

• Perl
