Multiple Inheritance vs Role

Thursday, Nov 7, 2024 by Mohammad Sajid Anwar Perl

In the world of Perl, we all believe in this philosophy for Multiple Inheritance in general: Don’t use multiple inheritance if you can do it in any other way. To address this, there is a general consensus to use roles. Personally, I have never had to deal with multiple inheritance. Being a big fan of roles, I want to simplify the comparison for my own understanding. With the inclusion of Corinna in core Perl v5.

Decode Hexdump

Saturday, Jun 18, 2022 by Mohammad S Anwar Perl

Those who know me personally, are aware that my background is Mathematical as I did Degree in Mathematics Honours in the year 1993-95. During my early days with COBOL and Pascal, I never dealt with Unicode or played with bytes. Even when I moved to C, I was still no where near it. Those with Degree in Computer Science always stay ahead in the understandings of these low level key aspects of programming.

Strawberry Perl

Monday, Jun 13, 2022 by Mohammad S Anwar Perl

Last week I wrote blog post Do you want to get started with Perl v5.36? where I shared my experience with the latest release Perl v5.36. I received this email today. The reality is, I never use Perl on Windows. And second never bothered creating .exe from the source file. I decided to give it a go, so first thing we need to download Strawberry Perl.

Get started with Perl v5.36

Saturday, Jun 11, 2022 by Mohammad S Anwar Perl

Do you want to get started with Perl v5.36? Honestly speaking I never bothered about any of the Perl releases before. But Perl v5.36 is very special and close to me. Why? Recently I have been sharing new features introduced in Perl dating back to v5.10, inspired by the book Perl new features v5.10 to v5.34 by brain d foy. I received a FREE copy of the book, a big thank you to brian d foy.

Taint in Perl

Thursday, Jun 9, 2022 by Mohammad S Anwar Perl

The "taint" always bothered me. I thought I knew it well but no. The obvious question, can I show a working example? Before I do that, let me share an incident with you. In the year 2019, I attended The Perl Conference in Riga. During the 3 days event, I gave couple of talks and one of them was "Protect your Perl script from common security issues". You can checkout my event report, if you are interested.

Memory Leak in Perl

Wednesday, Jun 8, 2022 by Mohammad S Anwar Perl

I always find the topic Memory Management very fascinating. Perl being the Perl, there is nothing you need to worry about. All memory management is done for us for FREE. Still, there was something, I always wanted to find out about memory management in Perl. All along, I knew that there is an easy way I can force my script to leak memory. How? Just create a data structure with circular reference.

HEADLINE With another Linked List related task, I am now enjoying it a lot. It also gives me the opportunity to work with Class in Raku. Learning Raku has changed my thinking a big way. The developer inside me is more organised than before. Also doing regular weekly challenge made me think from unit test point of view every time I come up with a solution. In fact, it dictates the design of my solution.

HEADLINE The Task #1 of Perl Weekly Challenge - 069 raised a very interesting question i.e. is 1 strobogrammatic number? So far, I got mixed response some says yes and some not. My first thought was Yes, it is but later changed my mind. It is controversial and I don’t want loose the focus on the task itself. Please remember the objective is to have fun and not to get into controversial domain.

HEADLINE The Week #068 is my 23rd week in a row participating the weekly challenge. For the first time, I created a package to deal with the “Reorder List” task. It really helped me in thinking straight when dealing with linked list. With the help my favourite CPAN module Moo, creating class is like piece of cake as shown below. package Node; use Moo; has v => (is => 'rw'); has c => (is => 'rw'); sub show_link { my ($self) = @_; my $head = $self; my @v = (); while ($head->c) { push @v, $head->v; $head = $head->c; } push @v, $head->v; return sprintf("%s", join ' -> ', @v); } I will talk more in detail later down below.

HEADLINE This week both tasks had one thing in common i.e. pairing two or more list. In the past, I have taken the help from CPAN module Algorithm::Combinatorics for such tasks. However this time, I wanted to get my hand dirty and came up with the following: # generate all possible combinations my @combinations = (''); foreach my $members (@data) { @combinations = map { my $member = $_; map $member.

Monday, Jun 22, 2020 by Mohammad S Anwar Perl, Raku

HEADLINES The week #065 started on a happy note when I received the contribution by Andrew Shitov. He doesn’t need an introduction, does he? He even blogged about his contribution. On a serious note, I got the sense that most of the Team PWC found the task Palindrome Partition very confusing. I must admit, I also realised when I solved the task myself. I noticed there are more solutions than what I thought initially.

HEADLINE At first, I thought Product SubArray is easy task. Therefore I went public categorised as Task #1. My definition of easy task is you just start coding without doing any ground work. However when I started coding, I had to take a pause and do processing in my head befoore coding. So then as per my definition, Product SubArray no longer consider as an easy task. After finishing the task in no time once I understood the flow, it turned out to be clean solution.

HEADLINE This week, I changed the format of my weekly blog slightly. Why? Well, I wanted to keep the Perl and Raku solutions next to each other so that it is easier for reader (me, mostly) to see the difference. It gives me immense pleasure to see the end result when I am done translating Perl solutions into Raku. It looks lot cleaner and precise.

Perl Weekly Challenge - Story so far ...

Tuesday, Jun 25, 2019 by Mohammad S Anwar Perl, Raku

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.

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].

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.

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.

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.

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.

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.

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.

Sunday, Apr 21, 2019 by Mohammad S Anwar Perl, Raku

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 Perl, Raku

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 Perl, Raku

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.

Sunday, Apr 14, 2019 by Mohammad S Anwar Perl, Raku

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) Perl

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.

Perl Weekly Challenge - 003

Sunday, Apr 7, 2019 by Mohammad S Anwar Perl, Raku

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.
