Hi there

If, like me, you are a fan of MetaCPAN then you must have noticed the latest changes to the MetaCPAN site. It is the introduction of new metric, "CPAN Bus Factor". Don't know what I am talking about? Well then you should read the blog post, which is a collaborative work by Neil Bowers and Olaf Alders.

It reminds me an incident from the past when I received an email from Neil Bowers about one of my CPAN distribution, IP::Info as he was reviewing CPAN modules for locating an IP address. Later he published his report on 8th Aug 2012. You can take a look collection of CPAN module reviews by him. If my memory serves, Neil also ran CPAN Weekly, for a while. I did join the mailing list and the received CPAN Weekly newsletter talking about a CPAN module and its usage every week. Unfortunately it is no longer active.

A long time ago, I used to be an active CPAN contributor. Unfortunately, because of time constraints, I'm no longer as active as I used to be. I even wrote a two-part blog post on the subject - "How to become a CPAN contributor?" - for perl.com in 2018. You can check out the posts, Part 1 and Part 2, if you are interested.

Why am I talking about CPAN contributions?

A friend of mine and fellow contributor to The Weekly Challenge, Cheok-Yin Fung, wrote a blog about her experience of uploading her first distribution to CPAN. It reminds me of my early days of struggle with CPAN. These days there is a lot of help available on various public platforms. I wish her all the best and welcome to the club of CPAN contributors.

I came across a very interesting blog post by JJ Merelo talking about Pull Request do's and don'ts. Very helpful advice for anyone looking to contribute to open source projects in general.

Enjoy the rest of the newsletter.
