The palindromic length

2026-09-28T10:00:20Z

This blog entry gives an excellent, bilingual implementation in Python and Perl for Weekly Challenge 392. Simon effectively shows elegant coding paradigms with a Python generator and itertools.combinations and an analogous Perl iterator approach to effectively solve problems related to word length product and palindrome transformations. Overall, the blog serves as an informative and succinct guide to solving problems in different programming languages.

Extruded Palindrome Product

2026-09-28T10:00:19Z

In this blog post, Roger offers a comprehensive, multilingual analysis of Weekly Challenge 392, showcasing an innovative way to solve this problem without taking any shortcuts. This article advocates the power of programming languages by demonstrating how manual set intersection using hashing can be done in Perl, while this is a built-in part of the Raku language. The effective use of language makes this content interesting and valuable to language enthusiasts, since the code snippets used are tied together with thorough explanations.

The Weekly Challenge - 392: Words Length Product

2026-09-28T10:00:18Z

In this blog, we can find Reinier Maliepaard's submission for Task #2, "Words Length Product" from The Weekly Challenge 392. Usually, his work is marked by effective and idiomatic Perl techniques in string analysis and set disjointness check within a well-organised framework.

The Weekly Challenge - 392: Convert Palindrome

2026-09-28T10:00:17Z

The entry from Reinier Maliepaard for Task #1, "Convert Palindrome", which belongs to The Weekly Challenge #392, can be found here. Although the page in its current view provides a simplistic layout of the task statement, Reinier has been presenting his contributions successfully with practical implementations based on proper methods.

Palindromes and products

2026-09-28T10:00:16Z

Peter has provided a clear and well-argued solution to the problem, "Convert Palindrome" in his blog post. His neat solution entails the reversing of the input string just the once and using it to compare substrings. This avoids having to perform repetitive string inversion operations and allows for a simple solution without worrying about edge cases.

Go hang a salami, I’m a lasagna hog!

2026-09-28T10:00:15Z

Packy's article discusses the Weekly Challenge #392 in detail using various computer languages like Raku, Perl, Python, and Elixir. His analysis is simple and makes use of either recursive or iterative calculations to find the characters that should be appended at the end. The article is very interesting and rich in jargon, and it also mentions the famous song of Weird Al Yankovic Bob.

Perl Weekly Challenge 392

2026-09-28T10:00:14Z

Published by Luis Mochan, this post provides a great insight into concise Perl regex construction and some advanced forms of deferred regex evaluation ((??{...}), and evaluates a palindrome conversion problem in a single substitution step. The functional pipeline method for Task 2 merges map, grep, and dynamic regex character comparison, which allows him to create idiomatic and expressive one-liners supported by concise explanations.

The Weekly Challenge 392

2026-09-28T10:00:13Z

This publication presents excellent, optimal solutions in both Perl and Python, with explanations tracing the logic of every task. The decision to use a 26-bit integer bitmask for Task 2 is a brilliant optimisation; the task is accomplished by performing O(1) bitwise AND operations instead of set-intersection checks. Moreover, the implementations are clean and idiomatic in both languages and are easily connected with the original constraints of the problem.

Perl Weekly Challenge: Week 392

2026-09-28T10:00:12Z

This blog offers a clear and structured guide for both challenges of the Perl Weekly Challenge, providing practical example solutions in both Perl and Raku. It simplifies complex string manipulation and set operation problems by breaking them down into simple code snippets accompanied by useful narrations.

Convert Product

2026-09-28T10:00:11Z

Arne's blog post presents a straightforward, neatly organised solution to the Perl Weekly Challenge #392 while using Raku's remarkable built-in features. It demonstrates Raku's notable idiomatic features well, such as string processing using .flip, subset matching through comb, and set operations with help of the ∩ operation.

TWC392

2026-09-28T10:00:10Z

Ali presents neat, practical, and idiomatic Perl approaches to solving problems related to The Weekly Challenge #392, showcasing straightforward and easy-to-understand algorithms for string processing as well as set-based filtration. The use of unit tests with the help of Test::More is linked closely to the code and ensures proper functioning if the code is clear and easy to follow.

RECAP - The Weekly Challenge - 392

2026-09-28T10:00:09Z

Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Convert Palindrome" and "Words Length Product" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.

pperl 0.6.20 - The Player of Games

2026-09-28T10:00:06Z

PetaMem's new release, pperl 0.6.20, has brought many performance improvements, achieving up to 7.3 times improvement over node.js according to Benchmarks Game performance metrics due to JIT optimizations including bump-arena tree builds and SIMD intervals proof. The release has also given rise to a 52 times faster Memoize due to compiled cache hits, made possible by the native integration of the 3D graphics with the help of Rust's wgpu crate, and provided a lot of new documentation.

QUERY in Dancer2

2026-09-28T10:00:05Z

The post discusses extending the Dancer2 web framework with preliminary support for the new HTTP QUERY method (RFC 10008). It covers some simple changes made to Dancer2's fundamental modules (DSL, Request, Types), an extensive test suite provided through Plack::Test, and working examples of REST API querying.

A NetAddr::IP Trial Release

2026-09-28T10:00:04Z

NetAddr::IP has been introduced a beta release 4.080_01 under the guidance of a new maintainer. Vital improvements have been introduced to the module in the new version. Invalid legacy behaviors have been eliminated as well. It’s noteworthy that the testing suite has been fully updated to Test2::V1, thereby getting wider CI coverage for the modern Perl versions.

#792 - Hacktoberfest

2026-09-28T10:00:00Z

Hi there,

October is quickly approaching, and so is Hacktoberfest! Whether you are an expert CPAN author or you are making your first contribution to the world of open source, there are many CPAN projects in the Perl community that are ready for your pull requests. Participation in Hacktoberfest is a fantastic way to show appreciation for the tools you use and benefit from, resolve that annoying bug in the CPAN project you like, or assist maintainers to create better documentation and testing coverage for the whole project.

While you are doing open-source programming, do not forget that the festive season for blogging is nearing as well. The Call for Papers for the Perl Advent Calendar is open, and the organisers are searching for new and bright ideas. You do not have to write a long and serious article. Short reports about projects from CPAN that deserve more attention, original ideas, or something else that can be of help are all very welcome.

In case you've been creating an idea or you have a specific module you'd want to showcase, you can visit the project repository for an early submission of your proposal. This will allow you to block a day on the calendar. Getting some quick Hacktoberfest contribution alongside creating an outline for an article is an ideal strategy to get maximum benefits this fall!

Perl v5.45.3 is now available! This latest version has introduced one of the most useful features in the language's core syntax: four new undef aware equality operators (equ, neu, ===, and !==). These operators simplify scalar comparisons without producing warnings about uninitialised values or converting undef to 0 or an empty string, the operators treat undef as a real value equal only to itself. If you are testing on the blead track, try these operators; however, remember to suppress experimental warnings using "use experimental 'equ';"; once you do! I have created simple script, you can try it yourself.

Enjoy rest of the newsletter.
