This week in PSC (192) | 2025-05-22

All three of us attended.

  • We discussed the situation with readline and the filehandle error flag once again, starting over by revisiting the basic premise of the error flag. We think we now have a better understanding the overall situation, and this led us to a different approach about how to correct the overall situation, which we will outline as a proposal soon.
  • We have been wanting to revert #22465 but wanted to include a testcase that demonstrates why, which we hadn’t gotten to. In order to get this into the looming final dev release, we talked through what the testcase needs to look like, and will submit a pull request ASAP.
  • We caught up on new issues and pull requests for release blocker triage. We then reviewed the state of our current release blockers, some of which have been resolved, and one of which (#23026) we demoted based on our new understanding about the readline situation.

Learning XS - List context

Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This third post introduces you to list context in XS.

The sculpture shapes the sculptor.

Parenting aint easy. Certainly it is often something your kids teach you. Even worse, it often starts with ”<INSERT_KIDS_FRIENDS_NAME>’s dad lets him do <INSERT_CURRENTLY_PROHIBITED_ACTIVITY>”. In this constant battle to shape your offspring into a model citizen, with the values you value, and turning him/her into a self-sustaining organism, one applies tools that enhance particular features, remove the superfluous or the undesirable.

AWS S3 Encryption


AWS S3 Encryption isn't as complex as I thought initially. I had fun playing with it. You can give it a try too. Please check out the link below for more information.

This week in PSC (190) | 2025-05-09

A meeting with full attendance.

  • We caught up with new issues and pull requests without finding any new release blockers.
  • We went over the state of the perldeprecation and perlexperiment POD pages. We found that perlexperiment does not yet reflect the change in direction regarding smartmatch. Other than that we saw nothing to do.
  • We went over our options regarding readline again at length. We concluded that we are not yet sure about the big across-the-board change to I/O functions, and are definitely too far into the release cycle to undertake a fishing expedition. But we don’t want to leave this problem entirely unaddressed during this cycle, and the change proposed by Tony Cook is a strict improvement, even if only a minimal one. So we decided to ship it, possibly with a slightly different implementation that we may suggest.

Julia in cruiser mode

Yes, this is a Mandelbrot fractal with three heads. No cloning needed, just multiply z to the power of four and proceed as usual. Well all this and so much more contains the latest release of Juliagraph 0.7. Intro here. All I wrote about the Cellgraph and Harmonograph applies again, more features, better controls and ... you can cruise the fractal by mouse.

This extended meeting took place between the three of us in person over several days at the PTS 2025 in the beautiful city of Leipzig.

Learning XS - What is in my variable

Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This second post introduces the fundamentals of type checking variables in XS.

Writing a 1GB file in perl

One of my pleasures in perl is learning the C language again. Something about the perl language makes it easier to write C, but while sharing the same space in my brain.

So how can I write a trivial program to write exactly one GB (2^30) of data to disk?

first in perl- (Of course you prototype in perl!)

But since my c program is cleaner, here’s the C program

This week in PSC (186) | 2025-04-10

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.

Learning XS - How to create an object

Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This first post introduces the fundamentals of creating an perl object from XS.

Reaching 1.0

With the Harmonograph you can create beautiful and individual images within a few clicks. It's painting by pendulum. I already gave here an introduction. So let me just explain what is new:

Type::Tiny 2.8.0 Released

What's new?

  • The BoolLike type constraint accepts boolean.pm booleans.
  • Type::Params offers some improvements for DWIM named parameter processing.
  • More shortcuts are provided for exporting parameterized versions of type constraints.

Faster Readonly variables with Const::XS

So, what exactly is a Readonly variable in Perl? A readonly variable is one that, once assigned a value, cannot be changed. Any attempt to modify it will trigger a runtime error. This mechanism enforces immutability, ensuring that critical values remain untouched and are protected from accidental or unauthorised alterations.
