Hi there! While we are still low on articles we had a good start in the WhatsApp group I mentioned 2 weeks ago. People introduced themselves and there were some light conversations. You are welcome to join us and write a few words about yourself. There are also a number of Perl related events on the horizon in Paris and Berlin and the virtual event I organize. Finally I published the Code Maven Academy site where there are already 140 hours of videos including 30 hours related to Perl. I'll keep recording these during live events and participants of my events will also get a discount coupon. Enjoy your week! Gabor Szabo |

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 Jorg Sommrey The article provides a clear and well-structured exploration of the challenge, combining thoughtful algorithmic reasoning with an elegant implementation. The use of Perl and PDL demonstrates both efficiency and creativity, making the solution not only correct but also technically insightful. Overall, it's an excellent example of concise problem analysis paired with expressive code. |
|
by W Luis Mochan The post presents a clean and well-reasoned solution to the Perl Weekly Challenge, with concise Perl code and a clear explanation of the underlying logic. The approach is methodical and easy to follow, demonstrating solid problem-solving and thoughtful handling of edge cases. | 
|
|
by Matthias Muth The post demonstrates a clean and thoughtful Perl implementation, with clear logic and well-structured code. The approach effectively handles both the self-referential string validation and the subnet-membership check, showing careful attention to correctness and readability. |
|
by Packy Anderson (PACKY) The post presents a clear and engaging walkthrough of the challenge, combining solid problem decomposition with readable Perl implementations. The explanation of the approach is practical and easy to follow, while the multi-language comparisons add extra technical value for readers exploring different idioms. Overall, it's a well-structured and insightful solution write-up. | 
|
|
by Peter Campbell Smith The write-up presents a clear and methodical approach to solving the Perl Weekly Challenge, with well-structured code and helpful explanations of the reasoning behind the solution. The implementation is clean and idiomatic Perl, making the logic easy to follow and reproduce. Overall, it's a thoughtful and technically solid exploration of the problem. | 
|
|
by Reinier Maliepaard The write-up provides a clear and well-structured solution to the challenge, with careful input validation and readable Perl code that emphasizes robustness. The step-by-step logic and defensive programming style make the implementation easy to understand and reliable. |
|
by Robbie Hatley The blog presents a thorough and thoughtfully structured solution to the Perl Weekly Challenge, combining clear reasoning with well-documented Perl code. The modular design and detailed explanations make the logic easy to follow while demonstrating solid engineering discipline. |
|
by Roger Bell West (FIREDRAKE) The post offers a clear and thoughtful walkthrough of solving the challenge with practical reasoning and well-structured code. Roger nicely explains the approach step-by-step, making the solution easy to follow while highlighting useful string-processing techniques. |
|
by Simon Green (SGREEN) The post provides a clear and practical walkthrough of both tasks from The Weekly Challenge, with well-structured solutions in Python and Perl. The explanations highlight useful techniques such as regex parsing, handling UTF-8 characters, and leveraging networking libraries like Python's ipaddress and Perl's Net::IP. |
