Hi there!
On Saturday, (evening for me, noon-ish in the Americas) we had an excellent
meeting and there are recordings you can watch. In the first hour I showed
some PRs I sent to MIME::Lite. You can watch the video here (
https://perlmaven.com/testing-mime-lite-video ). In the second hour we
changed the setup and we continued in driver-navigator style pair
programming. I was giving the instructions and two other participants made
the changes and sent the PR. Others in the audience made suggestions. So
actually this was mob programming ( https://mobprogramming.org/ ). As far
as I know, this was the first time they contributed to open source
projects. One of the PRs was already accepted while we were still in the
meeting. Talk about quick feedback and fast ROI. You can watch the video
here ( https://perlmaven.com/meta-data-and-github-actions-video ). Don't
forget to 'like' the videos on YouTube and to follow the channel!
I've scheduled the next such event. Register here! (
https://luma.com/perl-maven ). My hope is that many more of you will
participate and then after getting a taste and having some practice you'll
spend 15-20 min a day (2 hours a week) on similar contributions. Having
10-20 or maybe even 100 people doing that consistently will have a huge
impact on Perl within a year.
Before that, however, there is the FOSDEM Community dinner on Saturday (
https://perlfoundation.org/fosdem/community-dinner.html ). If you are in
Brussels.
Enjoy your week!

RECAP - The Weekly Challenge - 357
https://theweeklychallenge.org/blog/recap-challenge-357
=20
Enjoy a quick recap of last week's contributions by Team PWC dealing with
the "Kaprekar Constant" and "Unique Fraction Generator" tasks in Perl and
Raku. You will find plenty of solutions to keep you busy.
--------------
=20
Uniquely Constant
https://raku-musings.com/uniquely-constant.html
=20
The article skillfully uses Raku's comb, sort, and flip operations for
digit manipulation to offer a straightforward and idiomatic solution to
the Kaprekar's ongoing problem. It is both instructive and useful for
Raku programmers since it carefully addresses edge cases like
non-convergence and shows verbose iteration output.
--------------
=20
Perl Weekly Challenge: Week 357
https://www.braincells.com/perl/2026/01/perl_weekly_challenge_week_357.ht=
ml
=20
The post offers concise and illustrative Perl and Raku solutions to the
tasks from Week 357, particularly the Kaprekar Constant implementation
with examples that match the problem specification and well-explained
iteration logic. For Perl enthusiasts, its clear explanations and
references to actual Wikipedia details make the algorithms simple to
understand and instructive.
--------------
=20
Fractional Fix Points
https://github.sommrey.de/the-bears-den/2026/01/23/ch-357.html
=20
The Kaprekar Constant and Unique Fraction Generator tasks are explained i=
n
a clear and organised manner in this post, which also provides
step-by-step iteration breakdowns and solid examples to illustrate the
problem. For Perl/Raku learners taking on the Weekly Challenge, its
solutions demonstrate careful algorithm design and address important edge
cases, making it instructive and useful.
--------------

Perl Weekly Challenge 357: arrays everywhere!
https://fluca1978.github.io/2026/01/19/PerlWeeklyChallenge357.html
=20
Luca provides a thorough and systematic collection of answers to the
problems issued in all the languages (Raku, PL/Perl, Python and
PostgreSQL) and has demonstrated proficiency in both algorithmic
reasoning and the use and applicability of various characteristics of
each of these programming languages. The articles describe in detail how
to implement algorithms logically. As a result, readers are provided with
clean and accurate code as examples of how to successfully implement
these algorithms through the use of the listed languages.
--------------
=20
Perl Weekly Challenge 357
https://wlmb.github.io/2026/01/19/PWC357/
=20
The blog post provides a comprehensive overview of how to implement the
Kaprekar Constant and Unique Fraction Generator tasks in Perl. The
examples provided demonstrate the idiomatic (one-line) style of coding
that is used to represent both of the tasks. Additionally, the post
discusses how to handle exceptions such as non-convergence and uniqueness
of fractions, in a sensible manner.
--------------
=20
One Constant, and Many Fractions
https://github.com/MatthiasMuth/perlweeklychallenge-club/tree/muthm-357/c=
hallenge-357/matthias-muth#readme
=20
Matthias's solutions are easy to follow and use a typical hiring challeng=
e
style for each week. Each of his solutions adhere to the challenge's
requirements. Additionally, all of his implementations demonstrate good
programming practices for Perl.
--------------
=20
I could drink a case of you=E2=80=A6
https://packy.dardan.com/b/hq
=20
Packy's write-up for week 357 of the Perl Weekly Challenge offers a fresh
perspective on the challenge by telling an entertaining story that
incorporates the Kaprekar problem into the write-up. The article clearly
details how to implement the code and produces good results as well. The
final product is easy to understand and provides a fun, educational
experience to those tackling the challenge this week.
--------------
=20
Converging on fractions
http://ccgi.campbellsmiths.force9.co.uk/challenge/357
=20
A thorough explanation of the solution (both tasks) is provided in the
post. The Perl code included is easy to read and closely adheres to the
descriptions of each problem. Furthermore, the code has been written such
that it handles 'non-convergence' where applicable, with clear and
logical outputs as well as analyses of each step helping the reader to
learn about the algorithms and their correctness.
--------------
=20
The Weekly Challenge #357
https://hatley-software.blogspot.com/2026/01/robbie-hatleys-solutions-in-=
perl-for_20.html
=20
Robbie has provided full Perl implementations of the Kaprekar Constant an=
d
Unique Fraction Generator problems, including clear descriptions and
links to the source code for both projects. His article is very well
organised and user-friendly, allowing readers to quickly familiarise
themselves with both tasks and check out Robbie's own code
implementations.
--------------
=20
Uniquely Kaprekar
https://blog.firedrake.org/archive/2026/01/The_Weekly_Challenge_357__Uniq=
uely_Kaprekar.html
=20
The article provides all the vital information you need to comprehend the
fundamental algorithms of each challenge, including thorough code sample
illustrations, as well as an extensive discussion on iteration behaviour
and the reasons you don't want to use floating-point division in
programming.
--------------
=20
Fractional Constant
https://dev.to/simongreennet/weekly-challenge-fractional-constant-2mop
=20
This blog article describes how to perform both Weekly Challenge 357 task=
s
step by step, showing examples of useful and correct code in both the
Python and Perl programming languages, as well as considering input
validation and control structures for the Kaprekar constant, as well as
selecting the correct data structures to store unique fractions and
display them in sorted order. By comparing the differences between the
two programming languages alongside their implementation details, this
blog is a valuable resource to help those programming these challenges as
they learn about them.
--------------
=20
Kaprekar Steps & Ordered Fractions
https://dev.to/vinodk89/perl-weekly-challenge-357-kaprekar-steps-ordered-=
fractions-perl-pn
=20
The Kaprekar steps and unique ordered fractions problems are two
challenging problems; the author has provided a short list of Perl-based,
well-considered solutions to handling leading zeroes, digit sorting,
finding loops and sequence detection, and performing value-based ordering
of fractions with duplicate removal. These solutions outline the steps
taken and lessons learned while approaching each problem.

Hi there!
On Saturday, (evening for me, noon-ish in the Americas) we had an excellent
meeting and there are recordings you can watch. In the first hour I showed
some PRs I sent to MIME::Lite. You can watch the video here (
https://perlmaven.com/testing-mime-lite-video ). In the second hour we
changed the setup and we continued in driver-navigator style pair
programming. I was giving the instructions and two other participants made
the changes and sent the PR. Others in the audience made suggestions. So
actually this was mob programming ( https://mobprogramming.org/ ). As far
as I know, this was the first time they contributed to open source
projects. One of the PRs was already accepted while we were still in the
meeting. Talk about quick feedback and fast ROI. You can watch the video
here ( https://perlmaven.com/meta-data-and-github-actions-video ). Don't
forget to 'like' the videos on YouTube and to follow the channel!
I've scheduled the next such event. Register here! (
https://luma.com/perl-maven ). My hope is that many more of you will
participate and then after getting a taste and having some practice you'll
spend 15-20 min a day (2 hours a week) on similar contributions. Having
10-20 or maybe even 100 people doing that consistently will have a huge
impact on Perl within a year.
Before that, however, there is the FOSDEM Community dinner on Saturday (
https://perlfoundation.org/fosdem/community-dinner.html ). If you are in
Brussels.
Enjoy your week!

=20
The article skillfully uses Raku's comb, sort, and flip operations for
digit manipulation to offer a straightforward and idiomatic solution to
the Kaprekar's ongoing problem. It is both instructive and useful for
Raku programmers since it carefully addresses edge cases like
non-convergence and shows verbose iteration output.

The article skillfully uses Raku's comb, sort, and flip op=
erations for digit manipulation to offer a straightforward and idiomatic so=
lution to the Kaprekar's ongoing problem. It is both instructive and useful=
for Raku programmers since it carefully addresses edge cases like non-conv=
ergence and shows verbose iteration output.

The Kaprekar Constant and Unique Fraction Generator tasks =
are explained in a clear and organised manner in this post, which also prov=
ides step-by-step iteration breakdowns and solid examples to illustrate the=
problem. For Perl/Raku learners taking on the Weekly Challenge, its soluti=

Luca provides a thorough and systematic collection of answ=
ers to the problems issued in all the languages (Raku, PL/Perl, Python and =
PostgreSQL) and has demonstrated proficiency in both algorithmic reasoning =
and the use and applicability of various characteristics of each of these p=
rogramming languages. The articles describe in detail how to implement algo=

The blog post provides a comprehensive overview of how to =
implement the Kaprekar Constant and Unique Fraction Generator tasks in Perl=
. The examples provided demonstrate the idiomatic (one-line) style of codin=
g that is used to represent both of the tasks. Additionally, the post discu=
sses how to handle exceptions such as non-convergence and uniqueness of fra=
ctions, in a sensible manner.

Packy's write-up for week 357 of the Perl Weekly Challenge=
offers a fresh perspective on the challenge by telling an entertaining sto=
ry that incorporates the Kaprekar problem into the write-up. The article cl=
early details how to implement the code and produces good results as well. =
The final product is easy to understand and provides a fun, educational exp=
erience to those tackling the challenge this week.

A thorough explanation of the solution (both tasks) is pro=
vided in the post. The Perl code included is easy to read and closely adher=
es to the descriptions of each problem. Furthermore, the code has been writ=
ten such that it handles 'non-convergence' where applicable, with clear and=
logical outputs as well as analyses of each step helping the reader to lea=
rn about the algorithms and their correctness.

This blog article describes how to perform both Weekly Cha=
llenge 357 tasks step by step, showing examples of useful and correct code =
in both the Python and Perl programming languages, as well as considering i=
nput validation and control structures for the Kaprekar constant, as well a=
s selecting the correct data structures to store unique fractions and displ=
ay them in sorted order. By comparing the differences between the two progr=
