I would like to talk about blog written by some members this week. In the past, I went into the details of Perl 5 solutions mainly. Lets change the trend this time. Following blogs have been reported last week. Each blog is a text book in itself as it teaches you so many things. I enjoyed reading each and every blog. Please do read them when you get time.

The best part of the Perl Weekly Challenge is reading the blog by the members. Personally, I like the journey of an idea to final solution. If you look at closely all the blogs, every member has unique style. They all think differently but ends up with the same result. I have become fan of few in the last few weeks. Don’t get me wrong, reading code is fascinating but boring.

For the first time ever, I published RECAP blog before the weekly challenge. It is the sign that things are settling down. Members are using Pull Request more frequently to submit the solutions. Last Sunday, when I made the Challenge 004 public, I couple of people responded in no time. The first person was Kivanc Yazan and he announced it on Twitter. The next person followed him was @smokemachine. He has been regular since last week.

I noticed last week, less participation than the previous week. Why? Honestly speaking I have no clue. Could it be the questions were too tricky for the challenge? The week before, I received the feedback that the questions were too easy and simple. So I went for little trickier one this time. It seems that I have to balance it somehow. I am gratefull to all members submitting the solutions as Pull Request.

Every week, I release the challenge by email first and then on Twitter. I wait for about 30 minutes to get the first response to the challenge. I also look at the Google Analytics Realtime Chart to see how many users are reading the new challenge page and from which part of the world. Last week, I didn’t have to wait long, I saw the first reaction on Twitter from Khalid.

As received in response to the challenge by Philippe Bruhat. Highly recommended. Write a script or one-liner to remove leading zeros from positive numbers. As a filter: perl -ple 's/^0+//' Challenge #2 Write a script that can convert numbers to and from a base35 representation, using the characters 0-9 and A-Y. Those who remember The Perl Review Code golf contest may remember this challenge.

I noticed the timing of releasing the weekly challenge is not helping anyone in UK timezone as I released around mid-night. So if somebody who lives in other side where it is day they get to try the challenge first. I realised within few hours of making the challenge public, I starts getting feedback but none from UK member. It is only when it is Monday morning, I see reactions from them.

Last week challenge turned out to be a cakewalk for Perl 6 hackers. This shows my lack of knowledge of Perl 6. I have requested our inhouse Perl 6 experts to share some challenging questions. I already received few and kept in the challenge bank. I will use it in the coming weeks. Credit will be given to the hacker when published. We highly recommend that you submit you solutions as PR to the repository.

Welcome to the first weekly recap of “Perl Weekly Challenge”. Apology for the delay, I was supposed to release this blog with the second challenge of the series. I promise next blog is going to be on time. For the first time ever, the Monday 25th March 2019, was not depressing like any other Monday. Thanks to “Perl Weekly Challenge”, I was so busy following public reactions on Twitter. It was a memorable experience.
