At my job, I've instituted a lot of standard coding practices for our department. Here are a few that I think are habits of careful coders:
- use strict;
- use warnings;
- Use CPAN for as much of the work as possible
- Use tainting when dealing with CGIs
- POD or otherwise document everything (if not in POD, have a good reason why)
- $CGI::DISABLE_UPLOADS = 1;
- $CGI::POST_MAX = 4092; (or some other appropriate number)
code('Perl') || die;
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
