As I see, with knowledge of Perl and CPAN Modules and some sort of expertness, solving any problem is just an engineering problem, where you just have to put the pieces together and create a flow. But often times, I see some hard problems. What are those according to you?

• Huge Amount of Data
• Large Processing Time
• Different versions of Perl/OS
• Non-centralized data
• Unknown hardware failure
• Segmentation fault (out of memory)
• Lost code :-)
• Lack of code maintenance due to a left developer
• Unmaintainable code due to spaghetti nature

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Read Where should I post X? if you're not absolutely sure you're posting in the right place.

Please read these before you post! —
