For the last meeting of the year we were all present again.

• We have requested further input regarding our plan for TLS in core.

• We picked the ball back up that we dropped regarding point releases. They should be coming soon.

• We went over our findings so far regarding Perl 42. It looks like Perl versions will have to continue to be written with three components, so we will be stuck with a fixed .0 at the end. It’s slightly annoying, but we can live with it. We strategized about how to get more real-world data about feasibility, and discussed the possibility of releasing a perl-41.8 tarball alongside the regularly scheduled perl-5.41.8.

Someone keeps registering and posting articles with links to the “skale.space” domain despite the fact that I keep deleting them, so I thought I should reward them for their effort.

They are some kind of blockchain shop (yeah, shady activities, how uncharacteristic, right?), so I don’t know that my usual note that you might want to know that if you do business with them is all that relevant, but, there you go.

After hundreds of hours of work and support from lots of people, the long promised Journal is here. That link will take you to some more information, on there a link to purchase is available. All proceeds go to supporting future Issues and events of the SPC and Perl Community Organization. At this time, an electronic version is not available due to end-of-year time constraints.

It may seem silly, but we spent extra time making sure the book spine looks good on a bookshelf and will look even better as the Issues accrue. Get it while it's hot. ISBN-13: 9798218984748, 152 pages.

Some of us are currently preparing for a block of Science Perl Talks at the London Perl & Raku Workshop 2024. We appreciate the organizers of this event for the opportunity.

More will be posted after the LPW, but the SPC is hosting the Perl Community Conference, Winter 2024 on December 18th (Perl's 37th birthday! :-)). If you are interested in getting published in the next Issue of the SPJ (Winter 2024), we are still accepting extended abstracts, which is up to 1 full page in the Journal and a 5 minute lightning talk slot at the Winter Conference.

This week, we talked about some recent (and less recent) p5p threads:

• We discussed the sort thread briefly. We are waiting to see where it goes.
• We talked again about TLS in core, and reviewed a document from the CPAN Security Group. We want to talk about this more in depth next week.
• Discussion of the evalordie thread led us to talk about some form of in-core autodie pragma. We didn’t reach any conclusion.
• We noted that a maint release is overdue.

These are some answers to the Week 291, 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 October 20, 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.

Task 2: Poker Hand Rankings

A draw poker hand consists of 5 cards, drawn from a pack of 52: no jokers, no wild cards. An ace can rank either high or low.

Write a script to determine the following three things:

1. How many different 5-card hands can be dealt?

2. How many different hands of each of the 10 ranks can be dealt? See here for descriptions of the 10 ranks of Poker hands: https://en.wikipedia.org/wiki/List_of_poker_hands#Hand-ranking_categories

3. Check then the numbers you get in step 2 by adding them together and showing that they're equal to the number you get in step 1.

To the old Perl programmers out there looking for a new language to learn, I suggest giving Julia a serious look. I haven't had a language bring me this much joy since when I first discovered Perl a long time ago. If Perl is the grandpa, Julia is the granddaughter, and she's a really smart girl. She hangs out with scientists all day helping them make sense of their data, and she does it with a unique style.

To be continued...

(There's so much I want to say, but I don't want to commit the time to write it all down right now.)

Have you play with the new command line switch -g in Perl?

In my previous articles (#1 and #2), I covered the key activities of The Perl and Raku Foundation (TPRF), such as organizing conferences, providing grants, and other smaller initiatives. In this final article, I will explore TPRF's financials using publicly available data. As a U.S. 501(c)(3) nonprofit organization, TPRF is required to disclose their financial information to the IRS. As always, my opinions are my own and do not represent the views of the TPRF Board.

Revenue and Expenses: Year-to-Year Overview

Let's start by reviewing TPRF's revenue and expenses over the years.

Until 2019, both revenue and expenses fluctuated. However, in 2020, the financial landscape changed significantly, with both revenue and expenses dropping sharply. This trend continued into 2021, largely because TPRF held its conferences virtually, reducing costs but also potentially limiting revenue opportunities.

In 2023, TPRF experienced another sharp decline in revenue while expenses surged, leading to a large deficit of $140,213.

Here's a comparison of key financial figures over three years:

Task 1: Middle Index

You are given an array of integers, @ints.

Write a script to find the leftmost middle index (MI) i.e. the smallest amongst all the possible ones.

A middle index is an index where ints[0] + ints[1] + … + ints[MI-1] == ints[MI+1] + ints[MI+2] + … + ints[ints.length-1].

If MI == 0, the left side sum is considered to be 0. Similarly, if MI == ints.length - 1, the right side sum is considered to be 0.

Return the leftmost MI that satisfies the condition, or -1 if there is no such index.

Example 1

All three of us attended.

• We discussed the version 42 work on the psc/ppc0025 branch. We have an initial proof of concept that is almost good enough to test against CPAN in order to assess whether the plan is actually feasible and proceed from there. We discussed the timeline for this.
• We reviewed our plan for TLS in core. Some questions came up based on the conversation on the p5p thread and we need specific next steps now that Craig has provided a patch for the first one. We hashed out next steps to keep this moving.
• We briefly discussed the Random::Simple suggestion and decided we won’t address it at this time. (The inclusion of cryptography libraries in core will probably change the situation here in the foreseeable future.)

It's a little over a week until this year's London Perl and Raku Workshop. Here's a couple of things to note about the day.

The schedule is relatively fixed at this point, however if you haven't already starred the talks you plan to attend then please do so as this will inform any tweaks. The venue has a large room (150 people) and a smaller room (35 people) therefore it is helpful to know which talks might be heavily attended in advance so we can make sure those talks have enough space.

The venue, The Trampery in Old Street, is located a two minute walk from the Northern Line's Old Street tube station in central London. The Northern Line has stops at most of the major train stations in London, or trivial links to others, so we recommend taking the tube to get to the venue.

Task 1: Double Exist

You are given an array of integers, @ints.

Write a script to find if there exist two indices $i and $j such that:

1) $i != $j
2) 0 <= ($i, $j) < scalar @ints
3) $ints[$i] == 2 * $ints[$j]

Example 1

I am in the process of adding OpenWeatherMap support to Xasteria Weather for iOS and the proxy I built is in Perl. Since there was only an old module on CPAN which did not support the current API and was not easily updatable, I released Weather::OWM. It's a very simple module, similar to two other Weather modules I've released in the past (Weather::WeatherKit and Weather::Astro7Timer).
The OpenWeather API has a Free tier with both current weather and forecast, which makes the module useful to anyone interested in fetching weather for any location. E.g.

This week felt like a PSC reunion meeting. We extended invitations to join us for a discussion of the version change to a number of core contributors, and ended up joined by ex-PSC members Ricardo and Paul (Neil would have joined, but couldn’t make it).

There is skepticism but no strong opposition. The benefits are in some doubt, and resources to implement this will not come from core contributors. So we want to experiment on a branch to get a handle on feasibility and viability, which we hope will give us better data to evaluate the proposal and, we hope, allay any worries.

We also briefly discussed our intentions for the PPC process with Paul. We are thinking about an automatically generated status page on GitHub Pages.

Task 2: Jumbled Letters

An Internet legend dating back to at least 2001 goes something like this:

Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.
