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.

Herewith V 1.24

Cheers

All three of us attended. Other than administrivia we talked about formally documenting our supported platforms, and we intend to start a discussion on the mailing list about this soon. This is also a topic for the upcoming Perl Toolchain Summit.

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.

Back to the full roster, albeit with Philippe attending from on the road.

We mainly went over the list of PPCs, with an eye toward the fact that this release cycle is coming to a close.

• PPC0033 (ampersand method calls) is approved.
• PPC0030 (equ) does not have an implementation ready for this release cycle and PPC0031 (eq:u) is controversial.
• PPC0027 (any/all) is basically accepted other than needing its feature flag naming figured out.

As an aside regarding PPC0027, we reiterated that we would like use feature ':all' to go away if possible. It was never a good idea anyway, but has become untenable with the introduction of feature flags like indirect and bareword_filehandles, which we expect to have many more of in the future. Since their purpose is to be disabled rather than enabled by default, a simple toggling of all features (on or off) is a nonsensical request.

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!

Originally published at dev.to

In a previous blog post, I explored the modern way to write CGI scripts using frameworks like Mojolicious. But as pointed out in comments, despite the many benefits, there is one critical problem: when you actually need to deploy to a regular CGI server, where the scripts will be loaded each time and not persisted, frameworks designed for persistent applications add lots of overhead to each request.

CGI scripts have historically been written using the CGI module (or even more ancient libraries). But this module is bulky, crufty, and has serious design issues that led to it being removed from Perl core.

I just needed a few rows of UUIDs in a column of a spreadsheet, more for esthetics than anything else. uuidgen to the rescue.

At the time I didn't realize that uuidgen natively supports outputting multiple ids like so

uuidgen -C 8

The truly lazy path would have been to read the fine uuidgen manual.

Alas, supposing I needed to make multiple calls to uuidgen, I went with a Perl one-liner with a loop, as I couldn't recall the Bash loop syntax.

Here comes the laziness... I I didn't want to write something like this:

perl -e 'print `uuidgen` for @{[1..5]}';

I'm not so found of of perl's de-reference syntax these days, also that array reference/range was giving "the ick" as my kids would say. I needed something lazier, cleaner. I wondered if there were any default/exported arrays available to me that don't have too many elements to them.... Ah, I know!

This is a continuation of a series of articles about how to write XS libraries that are more convenient and foolproof for the Perl users, while not blocking them from using the actual C API.

If you spot anything wrong, or want to contribute suggestions, open an issue at the GitHub repo

Wrapping Transient Objects

One frequent and difficult problem you will encounter when writing XS wrappers around a C library is what to do when the C library exposes a struct which the user needs to see, but the lifespan of that struct is controlled by something other than the reference the user is holding onto.

Available now: Perl.Wiki.html V 1.23.

As from today, when I announce a new version of one of my TiddlyWikis, I'll list the 2 most recent parts of the change log. These are just copies of the most recent parts of the para called VersionInfo.

And why 2 parts? To help those who missed the last announcement.

Hi there!

Recently I tried this port of turbovision and was really impressed by it.

Now I want it to be available for Perl and in progress of coding it.
The progress is happening here

The progress is happening at a moderate pace.
Currently this runs okay on windows, and should also be okay everywhere else (not tested)

Lots of progress is done already.
Lots of work needs to be done.
I think I've crossed an imaginary equator recently and expect it to be finished in a month or two.
Please let me know here about your ideas, so I could add to the module.

PS.
This post is a slight misuse of the "blogs.perl.org" resource, because I want to create some small corner for developers discussion about it, so I am doing an attempt to invite interested people comment about development here.

• wiki
• discord
• please let me know what else

I had written a Math paper which was not good enough to be published in a journal, yet I wanted to have proof of the date I wrote it on so I could post the paper on the web without other people later being able to question who first came up with the idea.

The way I thought was more correct to do this was to publish the paper's sha256 checksum on the Bitcoin blockchain. Posting the SHA on social media (such as x.com) was not enough, as paid members can edit their old posts.

I got in touch with BBRTJ, the maintainer of Bitcoin::Crypto, who was very helpful in teaching me how to use his module and achieving my aim.

The goal, he told me, was to include the SHA256 checksum as the comment (technically the 'NULLDATA') of a small bitcoin transaction.

I'm resigning from the board position at TPF (The Perl Foundation) also known as TPRF (The Perl and Raku Foundation).

tl;dr

After eight years with the foundation board, the time has come for me to step down. While I'm leaving the board, I intend to remain an active member of the Perl community and continue contributing in meaningful ways for Perl users and developers. You'll still see me at various Perl events; and perhaps Raku ones, too.

Over the years, I've learned a great deal, (hopefully) made a positive impact, and had a lot of fun.

Why I'm stepping down #1. The board needs a refresh

As I've noted before, having long-term board members at a nonprofit has advantages and disadvantages. My resignation opens the door for new perspectives and ideas. The foundation's board has started searching for backfill, which is good for the board's long-term success.

People usually don't think about Perl's type system. Some would even mistakenly claim it doesn't have one. It is, however, a most unusual one that doesn't really look like anything else.

What is a type anyway? And what is a type system? I'm not going to precisely define it here, that's for academics, but generally speaking a type is a fundamental property of a variable or value that determines what operations can and can not be done with it and what invariants it must hold. In a strong type system it is a stable trait: it can't change over the lifetime of the value/variable.

In some type systems containers are typed (such as C) and values really don't exist separate from containers. In other typed systems containers are typeless but values are typed (e.g. Python, Javascript, …). There are languages where both values and containers are typed (e.g. Java, C#), typically this means that the container constrains the values in it.

Contrary to what you might expect, Perl has the latter sort of typesystem, but with a twist.
