Perl Weekly #665 – How to get better at Perl?

Originally published at Perl Weekly 665

Hi there!

A new subscriber of the Perl Weekly wrote me:

“I’ve used Perl for a while but I would love to be fluent in it. Please let me know if you have any advice.”

I think the best way is to work on projects and if you can find nice people who have time to comment on your work then ask them. Depending on your level you might want to try Exercism that has a Perl track for practice and a built-in system for asking for and getting feedback on the specific exercises. Even better, once you did the exercises you can become a mentor there helping others. That gives you another opportunity to look at these problems and help other people like yourself.

You can participate in The Weekly Challenge run by Mohammad S. Anwar, the other editor of the Perl Weekly.

Longer term I’d suggest to work on a real project.

Either create a project for yourself or you can start contributing to open source projects (e.g. CPAN modules). I’d start trying to contribute to active projects – so ones that saw a release recently. MetaCPAN has a page showing recent CPAN releases and the CPAN Digger provides some analytics and suggestions for recent CPAN releases. You can also contributed to MetaCPAN itself. This is also a nice way to contribute back to the Perl community.

Finally, Happy Passover celebrating the freedom of Jews from slavery. Let me wish to you the same we have been saying for hundreds of years at the end of the Passover dinner:

Next year in Jerusalem!

GitHub Sponsors – A series on giving an receiving 💰

Recently I decided to renew my efforts to get more sponsors via GitHub Sponsors. In order to understand how to do it better I am going to write a series of articles. This is the first one. At one point I’d also like to feature the Perl-developers who could be supported this way. So far I encountered two people: magnus woldrich and Dave Cross and myself. I’d like to ask you to 1) Add some sponsorship to these two people so when I write about them there will be a few sponsors already. 2) Let me know if you know about any other Perl-developer who is accepting sponsorships via GitHub Sponsors.

You joined the Perl Weekly to get weekly e-mails about the Perl programming language and related topics.
