Three of us again. Aristotle had limited time, Philippe and Graham stayed longer.
Some end of year reminders for CPAN Authors:
Do all of your modules have up-to-date contact information? If not, please release new versions with an updated email address in the AUTHOR section.
(And while you're at it, why not add a security policy to your distribution, so that people know how and where to report a security issue with your module.)
If you have a cpan.org email alias, does it forward to the correct email address?
And most importantly, if you are taking time away from maintaining Perl modules, please add ADOPTME or NEEDHELP as co-maintainers to mark your modules as available.
Thanks, and best wishes for 2025.

All three of us attended.
I have just released a trial version of PPI that includes the first shot at support for Perl signatures. After installing it, you can access this feature in the following ways.
For users of perlcritic and other PPI consumers:
use 5.035;
or higher in your codeuse feature 'signatures';
in your codePPI_CUSTOM_FEATURE_INCLUDES='{MyStrict=>{signatures=>1}}' perlcritic Work.pm
For consumers of PPI, in addition to the above:
PPI::Document->new( custom_feature_includes => ... )
PPI::Document->new( feature_mods => ... )
PPI::Document->new( custom_feature_include_cb => ... )
::Element->presumed_features
In a similar way as signatures, the core try feature is also recognized.

Another extended meeting, which everyone attended. Here’s a summary:
equ
and ===
are added to Perl, we think the negative versions (neu
and !==
) should be added as well.Someone wanting to make a social media site (such as a Mastodon server & web client for example) will want to allow its users to post URLs, for which previews will be shown in their posts.
These posts will be visited by a UserAgent, but there is the risk that a private IP (disguised as a FQDN hostname that resolves to it) will be in the URL's host, and that might cause security issues.
I could use LWP::ParanoidAgent, but then I'd have to fork a process to make the whole thing async, like a good Mojolicious site will be, and too many processes running can be a problem. Also I'd be missing on the many Roles that exist for Mojo::Useragent.
So I opened this issue on Mojolicious's github wishing for a solution.
Recordings of all talks from this year's London Perl & Raku Workshop are now available on YouTube: https://www.youtube.com/playlist?list=PLxNdCz2kBhVlzbVFcjwY6GkQf4zBhvwFn.
The sound quality of the recordings is not fantastic. We had some sort of issue that I've tried to fix in post. However, the auto generated captions by YouTube tend to be pretty good these days, so enable those if you have any problems understanding the speaker.
I go into the details a bit more about this in a personal blog post about the event, and how much effort is involved in trying to create the recordings, amongst other things.
Thanks to this year's sponsors, without whom LPW would not have happened:

These are some answers to the Week 293, Task 1, of the Perl Weekly Challenge organized by Mohammad S. Anwar.
Spoiler Alert: This weekly challenge deadline is due in a few days from now (on November 3, 2024, at 23:59). This blog post provides some solutions to this challenge. Please don’t read on if you intend to complete the challenge on your own.
You are given a list of dominoes, @dominoes.
Write a script to return the number of dominoes that are similar to any other domino.
$dominoes[i] = [a, b] and $dominoes[j] = [c, d] are same if either (a = c and b = d) or (a = d and b = c).
Example 1
Input: @dominoes = ([1, 3], [3, 1], [2, 4], [6, 8])
Output: 2
Similar Dominoes: $dominoes[0], $dominoes[1]
Example 2
We were joined by Leon Timmermans and Tim Legge to discuss plans for TLS support in core.
I was one of the organisers of the London Perl and Raku Workshop 2024, which happened last weekend. I've written about my own personal experience of this conference over on my personal blog.
Ever wanted to extract text from an image in Perl?
Here is my story to do the same.
Enjoy !!!
A longer blog post will follow, likely on my personal site (I'll try to avoid it sitting in my drafts folder for too long). In the meantime, thanks to all who attended, spoke, volunteered, helped, advertised, promoted, linked to, encouraged, and so on, this year's London Perl & Raku Workshop. I think it worked out.
Scarves. This year's surprise swag, a 20th anniversary scarf rather than the usual t-shirt. We sill have a few of these left and I'm happy to send you one if you cover the cost of postage and packaging (roughly 15.- CHF). Please email the organisers if you would like one. It wil be first come (emailed) first served. Any that remain I will probably take to GPW next year to give away.
Videos. I will be processing these over the next couple of weeks. Expect them to be available on YouTube sometime mid November.
Feedback. If you attended the workshop it will really help us if you fill in the feedback form. All questions are optional and it is anonymous. Approximately 120 people attended the workshop - if half of you can complete the form that would be smashing.
Next Year? We have no plans. Yet.
Thanks to this year's sponsors, without whom LPW would not have happened:
Just Aristotle and Graham for our first meeting of the new year. Not much progress since the last one due to Christmas, New Year’s, sickness, and other personal circumstances. We discussed our framing of the version bump, the timeline for a decision, and the fact that constraints push us toward a dummy .0 third version component as the simplest way forward.
These are some answers to the Week 292, Task 1, of the Perl Weekly Challenge organized by Mohammad S. Anwar.

You are given an array of integers, @ints
, where the largest integer is unique.
Write a script to find whether the largest element in the array is at least twice as big as every element in the given array. If it is return the index of the largest element or return -1 otherwise.
