PAGI (Perl Asynchronous Gateway Interface) is a new specification for async Perl web applications, inspired by Python's ASGI. It supports HTTP, WebSockets, and Server-Sent Events natively, and can wrap existing PSGI applications for backward compatibility.

This article demonstrates Perl's continued relevance in cutting-edge fields by showcasing integration with MXNet, a major deep learning framework. The ability to build convolutional neural networks (CNNs) in Perl for image classification represents significant technical sophistication.

by Rawley Fowler

The article demonstrates sophisticated understanding of developer tooling ecosystems and community trends. The comparison between 2009-2010 surveys and the 2025 results shows deep insight into how Perl development practices have evolved while maintaining continuity.

by Dave Cross (DAVECROSS)

The step-by-step progression from simple Perl script to full Docker deployment serves as an excellent tutorial on modern Perl module distribution. It shows how a well-designed module can serve diverse audiences from command-line power users to web developers to DevOps teams.

by Gene Boggs (GENE)

The step-by-step approach from "need to identify devices" to "controlling a synth" serves as an excellent mini-tutorial. The mention of related modules (MIDI::RtController, MIDI::RtController::Filter::Tonal) provides helpful pointers for readers wanting to explore further.

This article demonstrates enterprise-grade security automation using Perl as a robust orchestration layer. The solution elegantly combines multiple security tools (Lynis for auditing, ClamAV for malware scanning) with professional email reporting.

This article successfully teaches professional API integration through storytelling, making technical concepts accessible while demonstrating production-ready Perl code patterns. The holiday theme enhances rather than distracts from the educational content.

This article beautifully demonstrates transitioning from a polling-based API client to a webhook-based service - a common and important architectural pattern in modern web development. The scenario of "crippling ToyCo's servers" with excessive polling is both realistic and educational.

This solution demonstrates sophisticated software design with the strategic use of Storage::Abstract to create a clean abstraction layer between business logic and data storage. The anticipation of changing storage requirements and preemptive abstraction is professional forward-thinking.

Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Good Substrings" and "Shuffle Pairs" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.

by Ali Moradi

This implementation demonstrates elegant Perl craftsmanship. The good substrings solution is particularly clever, using a regex lookahead to capture all overlapping 3-character substrings in one pass, then filtering to ensure no repeated characters - a beautifully concise one-liner.

by Arne Sommer

The solutions demonstrate strong understanding of both algorithmic thinking and Raku language features. The shuffle pairs solution is particularly clever in its use of canonical forms and early termination conditions.

by Bob Lied

The Perl implementation demonstrates clean, readable code with thoughtful organization. The good substrings solution uses efficient array slicing and clear manual comparison logic that's easily understandable.

by Jorg Sommrey

This is an exceptionally elegant Perl implementation showcasing expert-level Perl idioms. Both solutions exemplify Perl's philosophy of "making easy things easy and hard things possible" with concise, expressive code that solves the problems elegantly without unnecessary complexity.

by Luca Ferrari

This is a comprehensive and impressively diverse implementation across multiple languages and environments. The Raku solutions showcase excellent use of the language's functional features. The PL/Perl implementations are particularly noteworthy for their adaptability to database environments.

by W Luis Mochan

This solution stands out for its deep mathematical analysis and optimization. The Task 2 solution demonstrates remarkable theoretical insight by using modular arithmetic with modulo 9 to significantly reduce the search space - achieving a 5.2x speedup is an impressive feat of algorithmic optimization.

by Packy Anderson (PACKY)

This solution demonstrates exceptional cross-language programming skills with clean, idiomatic implementations across four different languages (Raku, Perl, Python, Elixir). The consistent algorithmic approach while respecting each language's unique idioms shows deep understanding of multiple programming paradigms.

by Peter Campbell Smith

Both solutions showcase excellent Perl craftsmanship with thoughtful comments, clear variable naming, and robust handling of edge cases. Peter demonstrates both theoretical understanding (mathematical bounds, algorithmic complexity) and practical implementation skills.

by Robbie Hatley

This is a masterclass in professional Perl documentation and code structure. The solutions feature comprehensive POD documentation with clear attribution, problem descriptions, notes, and IO specifications - demonstrating exceptional software engineering practices.

by Roger Bell West (FIREDRAKE)

This solution demonstrates elegant Perl craftsmanship with a particularly clever approach. Using a regex with a lookahead assertion /(?=(...))/g to capture overlapping substrings is an expert-level Perl idiom that showcases deep understanding of the language's regex capabilities.

by Simon Green

This solution demonstrates excellent cross-language programming skills with clear parallel implementations in both Python and Perl. The Task 1 solution is elegantly simple - the Python version using set(substr) for uniqueness checking and the Perl version using a hash with early returns showcase appropriate idioms for each language while maintaining the same algorithmic approach.
