Hi there,
We are excited to announce that The Trampery, located on
Old Street in London, will host the London Perl Workshop
2025 on November 29, 2025. Bring your thoughts, your code, your
queries and your excitement to this next must-attend Perl
community event. To help shape the day, the organisers are already taking
suggestions from sponsors and the community. We would like to express our
gratitude in advance to all of the sponsors who help make this event
possible. Our community thrives because of your support; if you or your
organisation are interested in sponsorship opportunities, please review the
information on the website ( https://www.londonperlworkshop.com ). This is
your chance to interact, learn, share and develop whether you're an
experienced Perl hacker, module author, maintainer or
someone who is interested in the language's future developments.
The Perl core team released the development release
Perl v5.43.4 concurrently with the announcement of the
event. This version provides the most recent advancements in
Perl's development and is a member of the blead
(development) branch. Please find the changes in the perldelta (
https://metacpan.org/release/EHERMAN/perl-5.43.4/view/pod/perldelta.pod )
page.
26th Oct marks the 30th anniversary of the Comprehensive
Perl Archive Network (CPAN), which has been driving innovation, teamwork
and the Perl ecosystem for 30 years. I can still clearly recall my initial
feelings of excitement and apprehension when I uploaded a module to CPAN,
knowing that it would be instantly mirrored globally. When CPAN was founded
in 1995, it was truly revolutionary. Built before GitHub even existed, it
gave Perl a superpower that no other language at the time possessed: a
global, searchable, installable archive of reusable code. The people who
created the archive as well as the archive itself are what most amaze me.
CPAN has always been primarily a human network, with volunteers running
PAUSE, tireless testers finding bugs before users ever notice them, authors
who ship with care and toolsmiths who make installations run more smoothly
each year. To celebrate the occassion, I uploaded v0.67 of
BankAccount::Validator::UK (
https://metacpan.org/dist/BankAccount-Validator-UK ).
Enjoy rest of the newsletter.

TWC344
https://deadmarshal.blogspot.com/2025/10/twc344.html
=20
This blog post successfully guides the reader through the process of
resolving two programming challenges and is technically sound and
well-written. It exhibits sound coding techniques and strong
problem-solving abilities. The main strength of the post is its
easy-to-understand, step-by-step explanation style, which makes it
suitable for programmers of all skill levels.
--------------
=20
Form Formation
https://raku-musings.com/form-formation.html
=20
The post is well structured and easy to follow, introducing the challenge
clearly and then solving it step by step. It uses clean, idiomatic Raku,
showcasing native language strengths like permutations, MAIN signature
validation and concise array/string transformations. The solutions are
compact yet readable, demonstrating how expressive Raku can be for
problems that would be verbose in other languages.
--------------
=20
Pick Up the Pieces
https://dev.to/boblied/pwc-344-task-2-pick-up-the-pieces-3391

Perl Weekly Challenge: Week 344
https://www.braincells.com/perl/2025/10/perl_weekly_challenge_week_344.ht=
ml
=20
This is a brief and useful article that emphasizes offering practical
solutions with little fanfare. The author demonstrates a get-it-done
mentality by using a "one-liner" approach for the first problem and a
simple brute-force permutation strategy for the second. The review will
draw attention to some crucial scalability and robustness considerations,
even though the solutions are functionally correct for the examples
provided.
--------------

Turning Arrays Into Arrays
https://github.sommrey.de/the-bears-den/2025/10/23/ch-344.html
=20
The blog post provides clear, concise and idiomatic Perl solutions to the
week 344 tasks. The post provides multiple examples for each task,
covering various scenarios and edge cases. This helps readers understand
the problem's nuances and test their solutions effectively.

Perl Weekly Challenge 344
https://wlmb.github.io/2025/10/20/PWC344/
=20
This is a sophisticated and well-engineered set of solutions that
demonstrates deep expertise in Perl, particularly with the Perl Data
Language (PDL). It provides multiple approaches for each task, showing a
thorough understanding of different algorithmic strategies and their
trade-offs. The code is professional, robust and well-documented.

A-ray Sunshine!
https://packy.dardan.com/b/ct
=20
This technical blog post is incredibly well-written and captivating. It
effectively achieves its main objective, which is to guide the reader
through a challenging programming problem while elucidating the reasoning
behind it, its dead ends and its elegant solution. In technical writing,
it's the ideal illustration of "show your work".
--------------

Hip, hip, array!
http://ccgi.campbellsmiths.force9.co.uk/challenge/344
=20
In the great majority of real-world use cases, this solution accurately
resolves the issue and is clear, practical and effective. It creates a
sophisticated one-liner by utilizing Perl's advantages in handling
strings and numbers. The fundamental requirement of the
problem=E2=80=94converting between array and numerical representations=E2=
=80=94is clearly
understood by Peter.

Bring your thoughts, your code, your<BR>queries and your excitement to this next must-attend <strong>Perl</strong><BR>community event. To help shape the day, the organisers are already taking<BR>suggestions from sponsors and the community. We would like to express our<BR>gratitude in advance to all of the sponsors who help make this event<BR>possible. Our community thrives because of your support; if you or your<BR>organisation are interested in sponsorship opportunities, please review the<BR>information on the website ( https://www.londonperlworkshop.com ). This is<BR>your chance to interact, learn, share and develop whether you're an<BR>experienced <strong>Perl</strong> hacker, module author, maintainer or<BR>someone who is interested in the language's future developments.<BR><BR>The <strong>Perl</strong> core team released the development release<BR><strong>Perl v5.43.4</strong> concurrently with the announcement of the<BR>event.

I can still clearly recall my initial<BR>feelings of excitement and apprehension when I uploaded a module to CPAN,<BR>knowing that it would be instantly mirrored globally. When CPAN was founded<BR>in 1995, it was truly revolutionary. Built before GitHub even existed, it<BR>gave Perl a superpower that no other language at the time possessed: a<BR>global, searchable, installable archive of reusable code. The people who<BR>created the archive as well as the archive itself are what most amaze me.<BR>CPAN has always been primarily a human network, with volunteers running<BR>PAUSE, tireless testers finding bugs before users ever notice them, authors<BR>who ship with care and toolsmiths who make installations run more smoothly<BR>each year.
