I spend most of my terminal time in bash and vim, so little slowdowns in either disproportionately drain my time and energy. Since mid-2019, I have smoothed over warts in those tools by creating new shortcuts and by learning more about what the software already offers!

Mojolicious apps come in two flavors, Lite or Full. Lite apps are great for proof of concept but Full is better for robust apps. Can you move up from Lite to Full? Absolutely, we call it "growing"!

Whim is a brand-new command-line tool (written with Mojo!) that lets you receive, process, display, and send webmentions from the command line.

Webmention is a recent, W3C-approved technology that aims to promote the proliferation of independent websites through a simple protocol of open, cross-domain notifications.

I have been obsessed with this technology for the past two years, and I will try to explain why, sharing a lot of resources for further study.

Mojolicious Core Team member Joel Berger discusses some of the features of the recent Mojolicious 9.0 release and how they can improve your web (and async) applications.

use Data::Random::Contact;
my $randomizer = Data::Random::Contact->new();
my $person       = $rand->person();
my $household    = $rand->household();
my $organization = $rand->organization();

DESCRIPTION

This module generates random data for contacts. This is useful if you're working an application that manages this sort of data.

It generates three types of contacts, people, households, and organizations.

If you declare use v5.36; (or a later version, like v5.38 or v5.40) at the top of your script, subroutine signatures are enabled automatically, and you no longer need to suppress any warnings.

Today, I will focus mostly on Time Complexity from the Perl point of view.

1. O(1) - Constant Time
2. O(n) - Linear Time
3. O(log n) - Logarithmic Time
4. O(n ^ 2) - Quadratic Time
5. O(n log n) - Linearithmic Time
6. O(sqrt n) - Square Root Time
7. O(n ^ 3) - Cube Time
8. O(2 ^ n) - Exponential Time
9. O(n!) - Factorial Time

Building desktop applications has traditionally been a challenge in the Perl ecosystem. While we have... Tagged with perl, c, xs, programming.

A piece of "heredoc" data can appear anywhere in a Perl expression. It starts with an initial operator written either << or <<~. The second variant with an added tilde ~, available since Perl v5.26, introduces an indented heredoc, where initial spaces on the left of each line are automatically removed by the interpreter.

Empty string as delimiter

The delimiter string can also be .. an empty string! In that case the heredoc content ends at the next empty line; this is an elegant way to minimize noise around the data.

Several heredocs can start on the same line, as in this example:

my @blogs = $dbh->selectall_array(<<~END_OF_SQL, {}, split(/\n/, <<~END_OF_BIND_VALUES));

A fat comma in Perl is a construct that doesn't involve a typographic comma! Visually it consists of an expression followed by an arrow sign => and another expression. This is used in many contexts, the most common being for initializing hashes or for passing named parameters to subroutines:

The Solution: Separate License Files
The simplest and most effective solution is to provide each license in its own dedicated file. This allows Licensee to easily identify and display both licenses. This is perfectly valid because the Perl 5 license explicitly allows for distribution under either the Artistic License or the GPL. Providing both licenses separately simply makes it clearer which licenses apply and how they are presented.

Perl came for free. How much have I contributed in return? Absolutely nothing.

I work as what I’d call an inside-contractor.

I learn much better from text than from videos.

Youtube-to-Webpage is a Perl script to create a webpage from a Youtube video with a transcript generated from the video's closed captions paired with screenshots of the video.

Lazyweb, why doesn't this regexp match in Perl 5.32.1, 5.34.3 or 5.18.2 but does in PHP and JS: perl -le 'print 0 + ("ABCDE" =~ m/ABCF|BCDE|C(G)/);' Changing nearly any character, including the C before the G, or removing the parens, makes it match.
