Perl Weekly Challenge - Story so far ...

Tuesday, Jun 25, 2019 by Mohammad S Anwar Perl5, Perl6

We are now 3 months old and growing fast every week with the support of wider Perl Community. The prime motto of the “Perl Weekly Challenge” is to promote Perl (be it Perl5 or Perl6). I was looking for fun way of doing it. Being, co-editor of Perl Weekly newsletter, I noticed that not many people blog about interesting use of the language. I must say, Perl6 community is doing far better than Perl5.

Continues from last week. For a quick overview, read through all questions and recap of the challenge first. This week was quite unique as we observed there were several submissions where submissions were based on existing solutions but were done in a more alternative and elegant way.

Couple of weeks ago, I tweet below about a surprise for all registered members. It is now time to annouce the surprise.

I noticed members taking on the optional API challenge more regularly. Before only handfull members bother taking the challenge. I am also happy to see familiar faces coming back to the weekly challenge after short break. I hope they continue with it and enlighten us. Adam Russell Adam solved the Fahrenheit-Celcius challenge in such a way that even a kid would follow it without any explanation. Simply Cool. He treated the second challenge of Identity Matrix in the similar fashion.

Continues from previous week. For a quick overview, read through the questions and recap of the challenge. Challenge #1 The Wikipage page have a good introduction and manual calculation of conversion of Arabic numerals to Roman numerals. Read Laurent Rosenfeld’s blog post for the finer implementation details. Most participants uses a hash to map between Arabic and Roman numerals. Since order of the matching roman numerals against the Arabic values is important, we’ll need to sort it before any conversion.

I came to know about one secret player of Perl Weekly Challenge just few days ago. Any guesses? He is the Damian Conway. He doesn’t need any introduction. My first encounter with him was when I bought his book Perl Best Practices. I have been a big fan of him since then. Checkout his blog. I would also like to mention another newly joined member Yozen Hernandez. He blogged first time ever that too about his solution to the Perl Weekly Challenge.

I would like to this opportunity to thank one of the respected member Kian-Meng Ang for the help in reviewing Perl 5 challenges every week. Checkout her last review if you haven’t seen already. Ever since I started reviewing the challenges, I am looking for volunteer to do the same for Perl 6. I know it is weekly commitment and can be tiresome. If we can create team of reviewers for each languages then it would be even more fun.

Last week was better than the previous week. I noticed big rush on Saturday and Sunday always. As we are getting into 8th week, members are getting the hang of it, which is nice. Adam Russell Adam once again came up with unique solution using pack and unpack to solve the challenge #1. I really liked the graph solution for challenge #2.

Last week was not very active in terms of number of participations. Having said that the quality of the solutions is always on the top. Some went for the kill, you can’t afford to miss it.

Perl Weekly Challenge introduced me to so many genious around the globe. It would be unfair to name a few. You know who I am talking about. The main objective of the project was to introduce Perl to more people and allow sharing the magic of Perl. In the last 5 weeks, I can say that I have personally learnt a lot from many greats. RECAP Here is the recap of last week challenge.

RECAP - Perl Weekly Challenge - 005

Monday, Apr 29, 2019 by Mohammad S Anwar Perl5, Perl6

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.

Perl Weekly Challenge - 005

Sunday, Apr 21, 2019 by Mohammad S Anwar Perl5, Perl6

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.

RECAP - Perl Weekly Challenge - 004

Sunday, Apr 21, 2019 by Mohammad S Anwar Perl5, Perl6

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.

Perl Weekly Challenge - 004

Sunday, Apr 14, 2019 by Mohammad S Anwar Perl5, Perl6

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.

RECAP - Perl Weekly Challenge - 003

Sunday, Apr 14, 2019 by Mohammad S Anwar Perl5, Perl6

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.

Proposed Solution for Challenge - 002

Monday, Apr 8, 2019 by Philippe Bruhat (BooK) Perl5

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.

Monday, Apr 8, 2019 by Mohammad S Anwar Perl5, Perl6

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.

Perl Weekly Challenge - 003

Sunday, Apr 7, 2019 by Mohammad S Anwar Perl5, Perl6

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.

Thursday, Mar 28, 2019 by Philippe Bruhat (BooK) Perl5

This is actually as we received in response to the challenge by Philippe Bruhat. Highly recommended. Challenge #1 Write a script to replace the character ‘e’ with ‘E’ in the string ‘Perl Weekly Challenge’. Also print the number of times the character ‘e’ found in the string. $ perl -E '$_=shift;say y/e/E/;say' 'Perl Weekly Challenge' 5 PErl WEEkly ChallEngE Historical note: y///c is called “Abigail’s length horror” by golfers and obfuscators (couldn’t trace where the term came from).
