Perl Weekly Challenge - Optional API Task

I have been thinking to do review of optional API task so far. I have now finally got the time. BACKGROUND During the Perl Weekly challenge 005, Gabor Szabo, Chief Editor of Perl Weekly newsletter proposed optional API task to the weekly challenge. He even suggested list of API that I could use every week. It took me couple of weeks to figure out the format and other formalities. Finally it was introduced with the Perl Weekly Challenge - 008.

Perl Weekly Challenge - Story so far ...

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.

Perl Weekly Challenge - 014

Without any further delay, we would like to announce the winner of Perl Weekly Challenge - 013 and the name is Laurent Rosenfeld. Many congratulations to Laurent.

This week, Joelle Maslak sent us the first solution in Perl6 as Pull Request [#265]. Then came Scimon Proctor, again in Perl6 as Pull Request [#266]. Kevin Colyer submitted the next in Perl6 as Github gist. By now, I started thinking where are all #Perl5 hackers. I didn’t have to wait longer, Pete Houston sent us the solution in Perl5 by email. Finally we had our first complete solution in Perl5 by Dave Jacoby as Pull Request [#271].

Kian-Meng Ang Weekly Review: Challenge - 012

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. Moreover, some of these show case the expressiveness of Perl programming language itself, which is also one of the key goal of this weekly challenge.

Perl Weekly Challenge - 013

Couple of weeks ago, I tweet below about a surprise for all registered members. It is now time to annouce the surprise. Few weeks ago, Peter Sergeant of PerlCareers contacted me by email and offered to sponsor the weekly challenge to make it more attractive. He offered the winner of weekly challenge $50 Amazon Voucher. We, Peter and I, worked out the formalities and other related issues. All registered members who contribute to the weekly challenge for the week will go into the ballot box.

RECAP - Perl Weekly Challenge - 012

I was little late in releasing the weekly challenge last time. If I remember correctly it was around 4am Monday morning. Still, by 9am (UK time), I had first solution as PR by none other than the Scimon Procotor himself. And within the next hour, he submitted the solution to the second challenge. By lunch time, I had one more member Ozzy submitted solution to the first challenge. This week, Joelle Maslak joined 100+ score club and became the second member.

Kian-Meng Ang Weekly Review: Challenge - 011

Continues from previous week. For a quick overview, read through all questions and recap of the challenge first. For those who are new to the weekly review post, the main purpose of weekly review is to document down interesting approaches of using Perl programming language to solve each week challenges. Code reading or review allows us to learn / relearn, discover / rediscover, and appreciate / reappreciate (some participants uses other programming languages in their day job) new, interesting, and quirky things accomplished with Perl (unfortunately Perl 5 for now).

Perl Weekly Challenge - 012

With every week, the team is growing and participation is also growing. I also love the fact that members even taking on optional API challenge regularly now. I hope, you are having fun solving weekly challenges as much as I am. RECAP Here is the recap of last week challenge. CHART Please take a look at the charts showing interesting data. I would like to thank everyone for their valuable suggestions.

RECAP - Perl Weekly Challenge - 011

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.

Kian-Meng Ang Weekly Review: Challenge - 010

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.

Perl Weekly Challenge - 011

I noticed regular flow of new members to the team of Perl Weekly Challenge. Some of them quite actively take part in the challenge as well as blog about it. Some while on vacation, didn’t miss to take on weekly challenge. I remember, one member, submit the solution from her sickbed. I am gratefull to each of them for their support. I am equally thankfull to those who take time and blog about their solution.

Next, determine whether a square number has at least five distinct digits.

Perl Weekly Challenge - 010

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.

RECAP - Perl Weekly Challenge - 009

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.

Kian-Meng Ang Weekly Review: Challenge - 008

Follow up on this week review of the Perl Weekly Challenge #008 of answers submitted by all the participants. Read the full question list and the recap of the challenge to have an overview before we proceed with our review.

RECAP - Perl Weekly Challenge - 008

The Challenge - 008 participation was same as the Challenge - 007 in terms of number of members participated.

She solved the third challenge in Perl5 and Perl6. Adam Russell Adam making good use of unpack() to solve the perfect numbers challenge.

Weekly Review: Perl Weekly Challenge - 007

Below is the write-up review (only covers Perl 5) of the Perl Weekly Challenge #007 of all the submitted answers. You can read the original questions first to understand the details of these two challenges. Challenge #1 If we read the question carefully, there are several steps to solve this problem. First, to find all niven number from 0 to 50 inclusively. Second, to find the sum of its digits of this range of number.

Perl Weekly Challenge - 008

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. [#1] [#2] [BLOG] Alicia Bielsa Alicia submitted the solution to the challenge #1.

RECAP - Perl Weekly Challenge - 006

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. Enjoy the code. Adam Russell Adam got the help from CPAN module Data::Dump and the end result is unbelievable simple. Check out his code. Alicia Bielsa Alicia submitted the solution to the first question.

Perl Weekly Challenge - 006

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

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

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

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

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

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

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.

RECAP - Perl Weekly Challenge - 002

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

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.

RECAP - Perl Weekly Challenge - 001

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.

Perl Weekly Challenge - 002

It is already time for the second challenge of “Perl Weekly Challenge” event. We have had very positive response so far. We will soon share the review of first challenge. You can send us your solutions by replying the same email that drops the weekly challenge to your inbox. If you are active on twitter then you can DM @PerlWChallenge as well. Or if you have GitHub profile then you can even submit your solutions as PR to the repository.

Proposed Solution for Challenge - 001

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).

A New Week a New Challenge

Welcome to the first task of the “Perl Weekly Challenge” event. Every Monday, we are going to propose 2 challenges, one aimed at Beginners and another for Experts. However you are free to choose the challenge you fancy. You can even attempt to solve both. As you know the choice of languages are Perl and Raku. You can solve one challenge in Perl and other in Raku, if you like.

Laurent Rosenfeld Weekly Review: Challenge - 008

Raku Solutions Weekly Review Task #1: Perfect Numbers This is derived from my blog post made in answer to the Week 8 of the Perl Weekly Challenge organized by Mohammad S. Anwar as well as answers made by others to the same challenge. The challenge reads as follows: Write a script that computes the first five perfect numbers. A perfect number is an integer that is the sum of its positive proper divisors (all divisors except itself).
