opcua_pipe_gateway is an OPC-UA client that allows reading and writing OPC-UA variables via command line interface, using STDIN for commands and STDOUT for results. The application is available in two implementations: a Perl version (opcua_pipe_gateway.pl) and a Python version (opcua_pipe_gateway.py).

There are two issues with event loop coding, related to the need to maintain an asynchronous, non-blocking style: It's harder to write and maintain than linear, blocking code. Despite all the asynchronous behaviour, it's still single threaded.

There is a new release, but is it just an exercise in rewriting code, or is it used?

by Gabor Szabo (SZABGAB)

We used this example during an online session. I would want to continue playing with the module and possibly sending PRs, but unfortunately the ones I already sent have not been accepted yet.

Dimitrios writes: "With the current solar maximum, I wanted to add aurora forecasting features to my iOS weather app, Xasteria. Instead of fetching text files from NOAA, I thought it would be nice for my weather proxy server to handle that. Hence I developed NOAA::Aurora and released it to CPAN."

Is it? Or is this a misunderstanding of what Vibe Coding is?

Shouldn't new features at least emit a warning if they are "overwriting" an existing sub with a new built-in?

For anyone interested in helping Joh shakedown PAGI docs in preparation for publishing to CPAN, he'd love feedback on the tutorial.

PAGI (Perl Asynchronous Gateway Interface) is a new web specification and reference server for Perl, designed to bring first-class async/await support to web development. Think of it as Perl's answer to Python's ASGI - a modern foundation for WebSocket, Server-Sent Events, and HTTP applications using Future and Future::AsyncAwait syntax.

Welcome to a new week with a couple of fun tasks "Min Abs Diff" and "Shift Grid". 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 "Max Words" and "Validate Coupon" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.

by Arne Sommer

The blog post provides high-quality, idiomatic Raku code. It successfully solves the programming challenges while acting as an effective demonstration of Raku's expressiveness and unique programming paradigms. The solutions are practical, well-explained, and ready for use.

by Bob Lied

Bob Lied's solutions represent high-quality, thoughtful Perl programming that balances elegance, performance, and maintainability. The dual implementation approach for Task 2 with accompanying benchmarks shows a deep understanding of Perl's performance characteristics.

by Jaldhar H. Vyas

Jaldhar provides concise, one-liner-inspired solutions for both challenges, with a focus on achieving the result in a single line of code for Raku and a similar spirit for Perl.

by Luca Ferrari

The primary strength is demonstrating the same logic implemented idiomatically across very different paradigms. This is highly educational. The solutions are not overly golfed.

by W Luis Mochan

Solutions are technically impressive, highly original, and demonstrate expert-level Perl mastery. The functional style, robust error handling, and sophisticated use of zip make these solutions outstanding from an engineering perspective.

by Matthias Muth

Matthias provides exceptionally well-considered and pedagogically rich solutions that focus heavily on code design, readability, and the thoughtful evaluation of Perl idioms, TIMTOWTDI. Solutions are characterised by a deliberate choice of clarity and maintainability over mere conciseness, backed by explicit reasoning.

by Packy Anderson (PACKY)

Packy's core philosophy is to solve the problem once, then port the functional, pipeline-based logic to other languages. This results in consistent, readable, and idiomatic solutions across the board.

by Peter Campbell Smith

Peter's solutions are methodically crafted, resembling production-grade scripts one might write for a business system. The code is not minimalistic but is instead self-contained, well-documented, and robust, with a focus on teachable insights.

by Robbie Hatley

The post presents a detailed plan or pseudocode for solving the problems before showing the final code. The solutions follow a direct, procedural style in Perl. They are correct but emphasize a straightforward implementation over brevity or exploring advanced language features.

by Roger Bell West (FIREDRAKE)

Roger provides a brief and focused look at the challenges for blog post, solving them efficiently in JavaScript and Raku. The solutions prioritize solving the problem directly over extensive commentary. Solutions are technically proficient, concise, and modern.

by Simon Green

Simon implements both tasks using straightforward, loop-based logic that prioritizes clarity and correct input handling. The solutions are methodical and include explicit checks for edge cases.

Great CPAN modules released last week.
