Hi there, Ten days ago I participated at an online event organized by the Toronto Perl Mongers. where we had some really nice presentations about OpenQA and the Open Build Service, both written (partially) in Perl. I hope they are going to organize more such events about other projects written in Perl. Last week I spent some time tracking down the LinkedIn profile of some of the authors who had entries included in the Perl Weekly and I also managed to include the picture of quite a few people. However I'd like to get your help to further enhance this. All the authors are described in the authors.json file. I'd love to get your help in tracking down the missing details. For some authors we don't even have the names. Many are missing the image and the other details you might find for others. In addition I'd like to further enhance the listing by adding a link to the github and gitlab profile of each author. Would you like to help? Send a Pull-Request! If we are already talking about contribution, we are going to have another online Perl Maven event contributing to a CPAN module. Register now! Enjoy your week! Gabor Szabo |

by Sawyer X (XSAWYERX) December 23rd is the annual Mega Load Test for the Christmas Eve delivery system. Every service (the Toy Inventory API, the Naughty-or-Nice Scoring Engine, the Elf Logistics Portal) suddenly wakes up to millions of requests. And every year, something new falls over. This year, it was the Toy Service. |

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 Lance Wicks.

by Mohammad Sajid Anwar (MANWAR) Welcome to a new week with a couple of fun tasks "Match String" and "Binary Prefix". 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. |

by Mohammad Sajid Anwar (MANWAR) Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Special Average" and "Arithmetic Progression" tasks in Perl and Raku. You will find plenty of solutions to keep you busy. |
|
|
by Ali Moradi The post provides concise, runnable Perl code that solves the stated problems for typical cases. |
|
by Arne Sommer This is a well-crafted, educational post. Arne successfully solves the challenges with idiomatic Raku, provides clear explanations, and thoughtfully explores the efficiency vs. elegance trade-off by implementing multiple solutions. | 
|
|
by Jorg Sommrey Special Average task uses a standard and efficient approach. The solutions correctly filter out the minimum and maximum values and calculate the average of the remaining numbers. Arithmetic Progression task employs a highly advanced and unconventional method. |
|
by W Luis Mochan This solution takes a mathematical, array-oriented approach using Perl Data Language (PDL), demonstrating sophisticated numerical computing techniques rather than traditional Perl list processing. | 
|
|
by Packy Anderson (PACKY) The post presents clean, readable, and correct solutions to both programming tasks in Raku, Perl, Python, and Elixir. It adopts a straightforward, practical approach without unnecessary complexity. Packy thoughtfully acknowledges trade-offs in their design choices. | 
|
|
by Peter Campbell Smith This is a well-structured, practical implementation with good documentation and error handling. Peter demonstrates solid Perl programming practices while making reasonable design decisions based on their interpretation of the problem requirements. | 
|
|
by Robbie Hatley This is a professional, well-documented, robust implementation with excellent attention to detail, defensive programming, and clean code organization. Robbie demonstrates advanced Perl expertise with thoughtful design choices. |
|
by Roger Bell West (FIREDRAKE) The blog post provides functionally correct and easy-to-understand solutions for two programming tasks. Roger makes deliberate, practical choices in their implementations, explicitly favoring simplicity over micro-optimizations for problems of "this scale." |
|
by Simon Green This post presents concise, readable solutions to two programming tasks Perl and Python. The solutions are algorithmically correct, efficient, and practically focused, making them suitable for real-world use. |
