Although we consider GitLab to be our preferred git hosting service (where private repos were already free), we do make use of GitHub when collaborating with clients on their code hosted there. As our clients typically use private repos, we likewise maintain a paid account so we can fork their code into a private repo. …
The 2019 European Perl Conference (formerly YAPC::Europe) has concluded. Below we have collected and summarized the write-ups published by community members who attended. If you have a write-up you’d like added to the list, please get in touch (post a comment below or reach out on Twitter). During the conference a vote was held, and …
The Perl community has a long tradition of packaging up tips and module reviews as the prizes in an Advent calendar that unfolds over the month of December. Each day you get to learn something new as a treat. Some embrace the Christmas theme and others don’t. But what they all have in common is …
a.k.a. “CGI is not dead”
We wanted to invite people to a Slack channel, but Slack provides no automated means of doing so. So we developed a simple CGI script, slack_invite.cgi, that accepts query parameters from a form and calls the Slack API to generate an invitation.

John Napiorkowski (Jnap) is perhaps best known as a lead developer of the Catalyst web development framework, at least until recently. His breadth of experience includes cloud-based web solutions, such as Amazon Web Services, Docker, Linux, and of course Perl. (He’s also …

However, a number of attendees journaled their experiences. Tim KingTim King is Lead Developer at The Perl Shop. Tim got his start writing real-time embedded software …
A few months ago, John D. Cook wrote about the viability of unpopular programming languages. His story starts with a comment about Perl 6, to which someone replied, “Does anyone actually use Perl 6?” (or words to that effect). “My first thought,” he writes, “was, I bet more people use Perl 6 than Haskell, and …
I ran across this the other day while writing some sample code for the next chapter of Testing Strategies for Modern Perl. How can we use long lists of symbols from an imported package and still keep the code readable? I usually prefer use statements of the form: use My::Module qw(symbol1 symbol2 symbol3); Except for …
The first part of this series described Test Hierarchy, a hierarchy of test classes that mirrors the classes under test, and explained why it’s an antipattern. Part two explored what makes a good unit test and why Test Hierarchy does not. This third and final post reflects on why programmers use Test Hierarchy and why …
The first part of this series described Test Hierarchy, a hierarchy of test classes that mirrors the classes under test, and explained why it’s an antipattern. For how common it is, this practice doesn’t even produce good unit tests. This three-part series has also been published as a combined essay, “Test::Class Hierarchy Is an Antipattern.” …
