Jörg has concentrated his efforts solely on providing a high quality Perl solution to this challenge. The way he solves "Scramble String" is especially impressive because he uses a recursive solution that processes challenging partitioning and swapping of…
In this article, there is a thorough comparison made between two languages: Perl and Raku. The many modern capabilities of Raku, such as having a Bag data structure and being natively supportive of methods for manipulating strings, resulted in solving the…
Bob has created a detailed breakdown of the Scramble String problem, looking at the need to use memoisation to avoid redundantly calculating recursive algorithms. Bob has developed a very clearly constructed solution to the Scramble String problem using t…

Arne's experience in comparing Raku's expressive power vs. Perl with respect to the solutions of these two challenges are at the heart of this review. He also demonstrates how to use Raku's built-in Bag and Any types to simplify complex logic with clean, …
Abigail used a clever recursive method to take on the challenge of the "Scramble String" problem. The use of clear base cases and logic to explore possible points to split and swap all contribute to the final solution being an excellent example of how to …
Abigail offers a superb example of processing text for the "Popular Word" task using the ability of Perl's regex engine to process words without considering case and complex punctuation marks. This solution is unique because it demonstrates a high-perform…
Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Popular Word" and "Scramble String" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.

Welcome to a new week with a couple of fun tasks "Missing Letter" and "Subset Equilibrium". If you are new to the weekly challenge then why not join us and have fun every week. For more information, please read the FAQ.
Dave dissects a really good looking SPAM email made by an AI LLM to show us all how the world will look in future with AI created outreach. Even though the spam had accurately scraped Dave's background and book titles, Dave believes that this creates the …
In his article, Todd explores some of the legal issues surrounding code that is generated by AI and available through CPAN, and whether or not these AI-generated contributions are eligible for copyright protection and/or a legal license. He also cautions …

In this article PetaMem discussed how through AI we will have access to new ways to enhance our creative processes (as opposed to replacing them), through developing a partnership with AI; allowing developers and creators alike use the technology of AI to…
In this blog post, Mikko argues that keeping project repositories publicly accessible is an important practice even when no new contributions are anticipated. Having a project public on GitHub preserves historical context, serves as an example of quality …
Ihe Perl Steering Council got together at the 2026 Perl Toolchain Summit (Vienna). During this meeting, the group discussed the current status of Perl 5.44. Most blockers have been resolved and EOL workflow has been put in place. Finalisation of details f…
Brett Estrade, who is a member of the Perl Community Conference (PPC) organising committee, has released a call for participants for the Summer 2026 PPC. He notes the group's success in the areas of scientific research and community building through the u…
Just a heads up: The next LPW is planned to be in November 2026.
Hi there,
I like to believe that I belong to the old school of testing i.e. Test::More. That being said, every now and then I come across a magical test workflow. One of them is App::Yath. The biggest and pleasant surprise is that both were pres

A wonderful illustration of Test-driven development is Simon's critique of Challenge 369. He found through tests that the sanitisation step of "Valid Tag", had to be completed before performing case formatting so that example 5 is handled properly. He als…
20 Apr
Roger's technical review offers an interesting side-by-side comparison of various string handling paradigms from multiple programming languages. The "Valid Tag" part of the review shows how Crystal's highly performant state machine implementation allows f…
20 Apr
The work done by Robbie within the "Valid Tag" review indicates a very well thought out way to approach hyphenated compound words as a single entity for case adjustment, in addition to providing an innovative solution for "Group Division", by utilising th…
Reinier has created a very good tutorial solution which showcases how to use the "Perl 4-argument substr function" to extract and remove data from a string using a while loop to do so iteratively and then using string replication for the final padding mak…
In Reinier's method, a model for defensive programming has been developed that features validation of input for real alphabetic values before processing. Also, he has taken a somewhat technical approach (transforming input to remove non-letter characters …
20 Apr
In his article, Peter presents a practical and polished approach to developing an order of operations for the sanitisation of strings. By organising the procedure so that lower case, regular expression character removal, and space & character combination …
20 Apr
In this post, Packy gives a thorough, contemporary example of string handling in Raku, Perl, Python, and Elixir. He creates a unique solution to the "Group Division" challenge by using the Raku function .comb with integer arguments to automatically divide…
20 Apr
Matthias Muth has written an impressive article on internationalisation (I18N) relating to pragmatic problem solving while still maintaining a strong long-term support model through thoughtful design choices such as those found within both the "Valid Tag"…
20 Apr
The post demonstrates exceptional compact Perl programming by distilling complex string processing procedures into "1.5-liners" that are quite efficient. For Task 1, he builds camelCase tags from a string of input values using the split, map, and join fun…
20 Apr
Luca Ferrari exhibits an incredible degree of technical ability through his creation of five unique environments in which to accomplish the Week 369 challenges. Those five programming environments are: Raku, Python, PostgreSQL (PL/Perl, PL/PgSQL, and PL/J…
20 Apr
In this post, we look at the approach both challenges in a disciplined and structured manner. The focus is on having code that is easy to maintain and easy to read. We have examples showing clean, modular Perl and Python code, and show examples of how the…
20 Apr
This article offers a detailed examination of the many aspects of the "Valid Tag" challenge and provides a well-defined "word" in order to enhance the accuracy of processing. The body of this technical paper describes Jorg's unique application of the Perl…
By taking advantage of mathematical precision and the crispness of concise syntax through the use of "one liners", Jaldhar has developed an efficient method for solving this problem, no matter if you're using Raku or Perl. Calculating the required amount …
20 Apr
In an idiomatic Raku implementation of the Group Division problem, as shown pretty clearly here by Arne Sommer, the gather/take construct is utilised nicely to collect the data clearly, and with the use of substr-rw for in-place string manipulation and th…
This post offers an extremely polished and versatile engineering design for the island program project. Abigail has shown advanced expertise by using a 'chunk-and-fill' method over many different programming languages (Perl, C, and less common languages s…
This post provides multiple amazing examples of technical versatility by providing a clean and direct solution written clearly in many different programming languages with tremendous flair, it shows great elegance in presenting the elegant and simple solu…

"The current PDL implementation in pperl covers roughly 3,000 assertions end-to-end: about 1,400 on the Perl-facing connector side and about 1,600 on the engine side. As of this writing roughly 98% of the connector assertions match upstream PDL 2.103 exac…

How to share memory between processes? A survey of a bunch od Data::* modules.
For a long time I have been trying to encourage Perl Module authors to include installation instruction when external libraries are needed. Even if only for one or two Linux distributions. This information should be in the README of the project.

Way more information about UTF-8 than I can fit in my head.
Hi there,
Every week I see a post declaring about something being dead. Agile is dead! Testing is dead!, Algol-68 is dead! I am so fed-up with this. So I am not going to link to the article that was discussing 5 dead programming languages.
