Originally published at Perl Weekly 767 Hi there! It was interesting to see how Rust started to eat Python from the inside out. Several Python modules and stand-alone tools were rewritten in Rust. Now as I can see there started to be a movement in Perl as well to rewrite some parts in Rust (e.g. PDL). Very interesting. People quite often ask me how could they find a job? Given that I have been self-employed providing training and contract development work, I don't have a lot of experience in job-hunting, but it seems if you can show your programming, creative, and learning capabilities then you will have a better chance landing a new job. So I recommend that people build some interesting open source project or contribute to some projects. I am mentioning this as I just saw an article about Chandra: Cross-Platform Desktop GUIs in Perl by Robert Acock and at the end of the article he mentions that he is looking for new opportunities. IMHO building new stuff and talking (or writing) about it creates a lot more opportunities in getting a job than only complaining about the lack of jobs. Good luck! If talking about contribution, probably one of the easiest thing to contribute is a test. It is also way more valuable than many people might think. If you'd like to contribute to an open source Perl project: 1. clone its source code; 2. Generate test coverage report; 3. Find the holes in the tests and write a test. Then repeat. If you are unsure how to do this, luckily the "Testing in Perl" course I am teaching these days will help you. Last time we saw how to generate and interpret test coverage reports. Next time we'll also see how to do mutation testing. You can watch the recordings from the previous sessions (free of charge for 10 more days) and you can join our next live session.

Articles PDL in Rust -- A Native Reimplementation of the Perl Data Language Very interesting that more of Perl gets a Rust reimplementation. Chandra: Cross-Platform Desktop GUIs in Perl "Chandra is a Perl module that lets you build cross-platform desktop applications using the web technologies you already know - HTML, CSS, and JavaScript - while keeping your application logic in Perl.". Sounds interesting to see where it goes. Introducing Object::Proto — A Prototype Object System for Perl Manage the health of your CLI tools at scale "Your services have dashboards, tracing, and alerting. Your CLI tools print to STDOUT and exit. When something breaks, debugging starts at the API gateway -- everything upstream is a black box. This makes no sense." Discussion Activity streams library/module for Perl Perl This week in PSC (219) | 2026-03-30 The Weekly Challenge The Weekly Challenge by Mohammad Sajid Anwar will help you step out of your comfort-zone. You can even win prize money of $50 by participating in the weekly challenge. We pick one champion at the end of the month from among all of the contributors during the month, thanks to the sponsor Marc Perry. The Weekly Challenge - 368 Welcome to a new week with a couple of fun tasks "Make it Bigger" and "Big and Little Omega". If you are new to the weekly challenge then why not join us and have fun every week. For more information, please read the FAQ. RECAP - The Weekly Challenge - 367 Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Max Odd Binary" and "Conflict Events" tasks in Perl and Raku. You will find plenty of solutions to keep you busy. Max Conflict Arne demonstrates how Raku can help with the "Max Conflict" problem using Raku's built-in support for intervals and sets. By using Raku's expressive syntax (like ranges and Bags), Raku has created an easy-to-read and mathematically intuitive way to solve problems that involve overlapping data. Overlapping Oddities The post contains an excellent technical breakdown of both terms using Perl programming language, along with the associated edge cases, such as how to handle timings that cross over midnight using modular arithmetic to resolve them. Additionally, his benchmark testing for different ways to manipulate binary strings provides measurable, statistical data on the efficiency of these algorithms. Odd Events The post explores time-interval logic and complexities of "wrap-around" (i.e., time zone?) events in a mathematically rigorous and fascinating way. Specifically, by introducing the idea of "complementary" events and making use of an ingenious duration-sum inequality, he presents an elegant, universal formula for simplifying conflict detection across the Perl and J programming languages. The Weekly Challenge 367 The post provides a very pragmatic and functional dual language reference to assist in solving PWC 367. He uses strin
