Re: Perl as a second language

Please fill in the ???

A lot of that depends on what platform you are writing your code for. I know that in my case I mostly deal with folks that are writing Java, JSP and other of that type of code for the Weblogic platform. I have shown some of the more receptive in that audience the beauty of writing stuff in Perl that doesn't depend on the overhead of the Java JRE to do back end maintenance for their applications. I've also show them how they can use Perl to detect patterns in application log files and send emails when those patterns are detected. Just a few of the items I've taught them.

God points. Could you elaborate a bit on the back end maintenance? What kind of things do you need to do there?	[reply]

What kind of things do you need to do there? So that I don't give away customer confidential information, let me instead enumerate some of the things I use Perl for to do back-end processing in some JSP/Servlet applications that I've created. Keep in mind there are ways to do this in Java as well, but in some cases I don't want the added overhead of the JVM/JRE. Cleaning out old records in database tabls and emailing the results Conversion of uploaded spreadsheets and/or CSV files to databsae rows Cleaning old temporary files the JSP application leaves behind. Backup of database to offsite system That's just a short list of things I have Perl doing behind the scenes. One of the items that I have Perl doing on one web application I maintain is Java is not allowed to send email directly. The capability exists, but there is no equivilant of Email::Valid to check for invalid email addreses. So the Java application queues up the email send request to a database table and a Perl script that awakens from cron checks the validity of the request, formats the email and sends it on its way.
