Lots has been going on. All of us showed up, though Aristotle had to join late and Philippe had to leave early, so the meeting was short but productive:

• We continued with the potential release blocker issue review and finished going over all 49 issues remaining at this time, of which we identified 11 of interest. There are now still 72 pull requests to review.
• We agreed to include the new Perl logo in the next release, but don’t yet know exactly how and where. That should be sorted out on p5p, and we will kick that off soon.
• We went over the latest point release news, where everything is finally on track. It is coming very soon.

My home page gives you access to:

o Perl TiddlyWiki V 1.25
o Mojolicious TiddlyWiki V 1.03
o Debian TiddlyWiki V 1.07
o Some other stuff...

App::ModuleBuildTiny is a relatively new authoring tool. It aims to be a relatively lightweight (at least to some other tools like Dist::Zilla) and newbie friendly tool. It supports two install tools: Module::Build::Tiny (obviously what it was originally designed for) and Dist::Build; it does not support ExtUtils::MakeMaker or Module::Build.

Couple of experimental features added to Map::Tube.

All three of us attended, but none of us had the time for significant discussion, so we decided to reclaim the time and make some progress on our various to-do list items.

I wrote very elliptically about this warning and received some helpful comments with the standard advice about how to proceed when encountering it. Except unfortunately that advice will be of no use when you encounter this warning.

Namely I should have been less cute about it and made it clear that I was specifically talking about a warning about a wide character “in substitution”. How can a s/// even possibly trigger a wide character warning, you ask? Beats me, to be entirely honest, even now, but: if you have a use locale somewhere, it turns out that it can. Because defeating that is what fixed the warning I was getting:

Control. That’s what we all desire and very rarely acquire. The natural restlessness that occurs when you watch one of your offspring flicking from one movie title to the next, barely glancing at the summary before rejecting it, is one of the reasons I don’t like family movie night. My daughter’s grip on the remote is as strong as her decision making skills are weak; I struggle silently to hold back any outburst that would expose my failing parenting abilities once again. I have to distract myself with thoughts of the good old days when the TV had only 4 channels and Teletext was the closest thing to internet. Desiring such regression is now getting much of a habit for me. But we change what we can, accept what we can’t and trust, often foolishly, that those blessed with control do the best for all of us. Ah, look. Another teen fantasy horror romance movie. Thanks a heap, Netflix.

The three of us attended.

• Preparations for the point release are now in full swing.
• In relation to that, we ran into infrastructure permissions discrepancies that have cropped up due to an absence of onboarding/offboarding procedures. We need to address both the immediate and long-term issues here.
• We started winnowing this release cycle’s issues for potential release blockers. Out of about 95 issues, we have so far reviewed half, of which we identified 8 of interest. Additionally there are 72 pull requests to review.

Herewith V 1.24

Cheers

In the last months of the previous century, I had to learn Perl to be able to teach it to professionals. It was my 28th language to use, but still took two years to understand deeply. As experienced assembler and C programmer, I was astound how much more of my ideas I could achieve with this new Swiss army knife in my hands. I fell in love with Perl.

Of course, the only way to learn a programming language well, is to use it for a larger project. So, I started to re-code the business shell scripts and websites to Perl. Part of it was sending automated emails to colleagues.

Your phase in life is probably different, but for my personal feeling it was not too long ago; for Internet's lifespan, the year 2000 is ancient history. The first spec for MIME headers in email were just 8 years old at the time, and many email features were still evolving.

All three were present.

• We went over developments on the point release front. Things are now finally moving, if slowly.
• We discussed some internal quality-of-life improvements to the PSC meeting workflow.
• We briefly reflected on our work as the PSC given our various personal circumstances this year.
• We discussed PPC 0027 (any/all), prompted by the Mojolicious::Lite DSL question. We went over its status, how the work got merged, and current issues with the design. We confirmed an already possible technical solution to the Mojolicious issue and agreed that it satisfies us for now, but we still intend to pick up the further issues at a later time.

Cellgraph 0.7 is out. (I introduced it here and there.) And I will tell you about the great new features in the next paragraph and how it helps you to play with logical structures and deepen your understanding of them. But first please let me mention the why!

We didn’t have a meeting last week. This week, everyone was here.

• We briefly talked about builtin. We think a numify function is quite necessary.
• We started reviewing release blockers for v5.42.
