I am always flattered to be invited to the Perl Toolchain Summit, and reinvigorated in working on MetaCPAN each time.
Currently I am focused on building on the work I and others did last year in setting up Kubernetes for more of MetaCPAN (and other projects) to host on.
Last week I organised the Road map which was the first thing we ran through this morning. I was very fortunate to spend the day with Joel and between us we managed to setup:
- Hetzner (hosting company) volumes auto provisioning in the k8s cluster
- Postgres cluster version (e.g. with replication between nodes)
I had a few discussions with other projects interested in hosting and this has helped us start work on what we need to be able to provision and how.. especially with attached storage which has been some what of a challenge but we are heading towards a solution.
These are some answers to the Week 277, Task 2, 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 July 14, 2024, known in France as Bastille Day, 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.
Task 2: Strong Pair
You are given an array of integers, @ints.
Write a script to return the count of all strong pairs in the given array.
A pair of integers x and y is called strong pair if it satisfies: 0 < |x - y| < min(x, y).
Example 1
Input: @ints = (1, 2, 3, 4, 5)
Ouput: 4
Strong Pairs: (2, 3), (3, 4), (3, 5), (4, 5)
Example 2
The deadline for talk and paper submissions to the 2024 TPRC has been Officially extended through April 20th for both the regular Perl and Raku tracks; and also the Science Track.
Update for the Science Track submissions, we have a small, but solid set of submissions and are expecting a few more. The Science Perl Committee is committed to helping anyone submitting a serious entry to succeed. If you're hesitating at all because you're afraid of getting rejected, please be reassured we want as many people to be part of this inaugural Science Track, as possible.
Please note, acceptable topics DO include white papers discussing implementation details of the Perl or Raku interpreters, experimental language features, implementations, benchmarks, etc.
I personally and strongly encourage you to submit an abstract to the Science Track. And if you don't want to write a paper, I strongly encourage you to submit a regular conference talk.

The three of us met, and:
- merged the deëxperiment PR
- agreed we should additionally discuss if the now-stable features
(
try, extra_paired_delimiters) should be included in the :5.40
feature bundle
- reported feedback from PPC implementors, which can be summarized as “life
happened, will get back to work soon”
- continued to triage latest reported bugs and look for release
blockers (Currently we have 8 potential blockers, though 2 are easy
documentation fixes)
- Maintainers and authors are found everywhere throughout our dependency trees. This includes the authors of the tooling others use for maintaining, building, testing, writing and running the infrastructure they depend on. Even maintainers depend on other maintainers.
- Maintainers’ mental health and well-being is also a dependency.
- So is their outlook on the sustainability of their projects, both in personal, technical, systemic and economic respects.
This means that personal, technical, systemic and economic well-being in the end are all actual and real dependencies* for the businesses that rely on these people and their projects.*
What can an ecosystem provide to make the lives of these maintainers easier in this regard?

Task 1: Count Common
You are given two arrays of strings, @words1 and @words2.
Write a script to return the count of words that appears in both arrays exactly once.
Example 1
Input: @words1 = ("Perl", "is", "my", "friend")
@words2 = ("Perl", "and", "Raku", "are", "friend")
Output: 2
The words "Perl" and "friend" appear once in each array.
Example 2
Talk submissions are still open, and we are seeking proposals on a wide variety of subjects. This includes language features, personal projects, applications like Koha, and anything that may be of general interest to Perl and Raku programmers.
To submit an abstract, please see the authoritative Science Perl CFP or for a standard talk visit the familiar Papercall site.
Please note it is our (the Science Perl Editorial Subcommittee) goal to be able to accept as many perl+science papers and posters as possible, as such our editorial process is designed to be very friendly.
Science Track Deadlines (initial submission is same date/time as the standard talk tracks):
- Abstract submission deadline: April 5th, 2024 (23:59:59 UTC)
- Abstract acceptance emails sent: April 15th, 2024
- Draft full paper due: May 15th, 2024
- Draft full paper feedback emails sent: May 31, 2024
- Final full paper due: June 7th, 2024
- Final papers approved: June 15th, 2024
PLEASE SPREAD THE WORD!
Thank you and I am looking forward to some very good things to see in Vegas, baby!

Task 2: Maximum Frequency
You are given an array of positive integers, @ints.
Write a script to return the total number of elements in the given array which have the highest frequency.
Example 1
Input: @ints = (1, 2, 2, 4, 1, 5)
Ouput: 4
The maximum frequency is 2.
The elements 1 and 2 has the maximum frequency.
Example 2
What is it good for?
If you’ve never worked with MooX::Role::Parameterized or MooseX::Role::Parameterized, you might wonder what is a parameterized role at all?
Roles are used when you need to share behaviour among several classes that don’t have to be related by inheritance. Normally, a role just adds a bunch of methods to the class that consumes it (there’s more, you can for example specify which other methods the role expects to already exist).
A parameterized role makes it possible to provide parameters for the consumed role. This way, you can adjust the behaviour for each consuming class.

Task 1: Complete Day
You are given an array of integers, @hours.
Write a script to return the number of pairs that forms a complete day.
A complete day is defined as a time duration that is an exact multiple of 24 hours.
Example 1
Input: @hours = (12, 12, 30, 24, 24)
Output: 2
Pair 1: (12, 12)
Pair 2: (24, 24)
Example 2

I attended YAPC::Hiroshima 2024 in Japan.
A few people asked me about the distinctions between YAPC::Japan and other Perl events worldwide, prompting me to write below. Before delving into the specifics, I must preface that my experience is primarily rooted in YAPC::Hiroshima 2024, the only YAPC::Japan event I attended. It's important to say that comparing Perl events across different regions isn't about establishing superiority or inferiority; organizing conferences requires considerable resources and effort irrespective of location. Each conference has its unique approach and metrics for success. The observations I offer are purely subjective and reflect my personal views.

Task 2: Replace Digits
You are given an alphanumeric string, $str, where each character is either a letter or a digit.
Write a script to replace each digit in the given string with the value of the previous letter plus (digit) places.
Example 1
Input: $str = 'a1c1e1'
Ouput: 'abcdef'
shift('a', 1) => 'b'
shift('c', 1) => 'd'
shift('e', 1) => 'f'
Example 2
If you have been following along with the efforts to add a Science Track to the TPRC, now is the time to seriously consider submitting a peer reviewed paper. The TPRC Call for Papers has opened with information on submitting to any of the 3 tracks.
