Welcome future Perl Maven!

What can you do here?

If you are a beginner, or would like to refresh your Perl programming knowledge, you can go over the Perl tutorial.

You will find a few advanced articles too, though most of the advanced articles are available to the subscribers of the Perl Maven Pro service only.

If you are interested to listen to or even see other Perl developers, the Perl Maven TV Show is a collection of such interviews.

CPAN, mcpan, MetaCPAN

Searching for a Perl module on Google will most probably lead you to a page on search.cpan.org, the old front-end of CPAN. By typing the letter 'm' in front of cpan.org in the URL, you can easily switch to MetaCPAN.

Pro: Testing timeout with cmp_ok

As mentioned earlier, the is() function compares the values using string-eq which is correct in 99% of the cases, but if you'd like to compare the values with numerical-== you can do it using the cmp_ok.

More than that, with cmp_ok you can compare the two values with any operator, so you can check if the actual value is, let's say, smaller than an expected value.

For example when measuring timeout, we cannot expect the result to be exact on the millisecond.

DWIM Perl for Linux; $^X vs $Config{perlpath}; Relocatable Perl; Test::Differences

The last couple of days I've spent re-building DWIM Perl for Linux using a cpanfile, carton, running builds on Travis-CI and on a Digital Ocean Droplet. DWIM Perl for Linux is a batteries included binary distribution of standard perl + lots of CPAN modules. The hope that it will make it extremely easy for people to get started using Perl. Without the need to encounter the installation headaches that might come with cpan.
