Hi there,
YAPC::Fukuoka 2025 is happening on 14-15 Nov 2025.
I’m also excited about LPW 2025. From our latest update from the organisers, the event is moving forward. They’re making every effort to ensure it happens, which is no small feat given the short notice. What’s particularly remarkable is that they’re managing this with just a two-person team.
They truly need our support, so please do reach out if you can help. The organisers are currently seeking sponsors, volunteers and speakers. I’ve tentatively submitted a talk proposal myself.
Hopefully, I’ll see you all at the event. The venue is expected to be confirmed this week. For the latest updates, please check the website.
Enjoy rest of the newsletter.

Online live-coding event.
Articles
Implementing Bitcoin in a dead language
An exceptional piece of technical writing that balances satire, technical depth and human vulnerability while showcasing significant software engineering accomplishment. It now implements BIP340 (Schnorr signatures), BIP341 (spending rules) and BIP342 (script validation).
A polymorphic quine
An exceptional deep dive into esoteric programming concepts that demonstrates profound computer science knowledge and creative problem-solving.
AWS S3 Bucket Events
Back to my favourite topic: AWS. In this post, I am showing how to tackle S3 bucket events using AWS Lambda.
CPAN
App::Test::Generator
This is a major improvement of the fuzz testing framework, a building tool that automatically generates comprehensive test suites from formal specifications.

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.
The Weekly Challenge – 347
Welcome to a new week with a couple of fun tasks “Format Date” and “Format Phone Number”. 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 – 346
Enjoy a quick recap of last week’s contributions by Team PWC dealing with the “Longest Parenthesis” and “Magic Expression” tasks in Perl and Raku. You will find plenty of solutions to keep you busy.
TWC346
For The Weekly Challenge, this is a strong, organised solutions post. Working code for both challenges is provided by Ali, who exhibits a straightforward and useful approach to problem-solving. The answers are clear and accurate.
Parenthesised Magic
This blog post is technically sound, informative and well-written. It successfully illustrates a typical Raku problem-solving technique: beginning with a simple, imperative approach and then refining it into a more idiomatic, succinct and potent functional solution.
Perl Weekly Challenge: Week 346
Jaldhar doesn’t just provide solutions but explores multiple approaches for each problem, analysing trade-offs between readability, performance and idiomatic style. The post is rich with technical insights, performance benchmarks and clever algorithmic thinking, making it both educational and intellectually stimulating.
Magic Parentheses
This is an excellent, technically complex post that demonstrates sophisticated Perl programming methods. Jorg exhibits a thorough understanding of mathematical optimization, regex engines and effective algorithm design.
really not inspired!
Welcome back Luca after the break, nice hack about tracking nesting levels in Raku.
Perl Weekly Challenge 346
This is an excellent technical blog post that demonstrates deep algorithmic creativity and strong problem-solving skills. It’s a genuinely novel approach that demonstrates deep understanding of the problem domain rather than just implementing standard algorithms.
Recursive Parentheses – But no Recursive Magic
This is a solid and insightful write-up by Matthias – concise, technically sound and pedagogically clear.
Whoa-oh-oh! Sing about parens!
This is a superb technical blog post that exhibits profound pedagogical understanding and remarkable programming proficiency in several languages.
(Magic)
This post blends practical implementation knowledge with sophisticated algorithms. Peter demonstrates a solid foundation in computer science and carefully weighs the pros and cons of various strategies.
All Aboard The Magic Parenthesis
This is a solid, practical technical blog post that demonstrates good problem-solving skills across multiple languages.
Longest Expression
Both tasks are implemented correctly, pedagogically and safely. The code favors clarity and correctness over performance, which makes sense for a challenge-focused context.
Rakudo
2025.44 Jimmy Wales on Audrey Tang
This is a high-quality community newsletter that successfully serves both technical and social aspects of the Raku ecosystem. It demonstrates an active, thoughtful community with meaningful technical content and important community developments.
