Hi there,
A few days ago, I wrote a blog post about CVEs. It was my first time looking at CVEs closely. Then I came across a reddit post discussing CVE-2024-56406. I am a bit confused, was this fixed in Perl v5.38.4 or Perl v5.40.2?
That said, it gave me something fun to dig into. I already know what I'll be doing next. During my search, I discovered the, CPAN Security Group, a community effort dedicated to handling security incidents on CPAN. Pretty cool!
Also the Perl Toolchain Summit 2025 needs our support as mentioned in the blog post. I'm happy to see my current employer, Oleeo, listed as one of the In-Kind Sponsors. Now, I'm curious to find out who the lucky team member is that gets to attend!. It's happening this year from Thursday May 1st to Sunday May 4th 2025.
I remember back in 2019, the summit was held so close to me, in Marlow, if I recall correctly. I've said it before and I'll say it again, I have to get involved in the MetaCPAN project. The main blocker last time was setting up the local development environment. I spoke to someone about it, can't remember who, and he mentioned the team was working on simplifying the setup process to make it easier for contributors. I haven't had a chance to check the current status, but I'm adding it to my ever-growing TODO list.
Happy Monday and enjoy the rest of the newsletter!

RECAP - The Weekly Challenge - 316
Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Circular" and "Subsequence" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.
Going Around in Sequential Circles
How often you see the do {} for construct? See it yourself in action. Great work.
TWC316
Usual suspect, map, index, split, join and sort are in the act together. Clever use, great work.
Subcircular
Don't underestimate the power of substr(). Is it same as in Perl? Find out yourself.
Not Gonna Reference John
Welcome back to blogging, hope to see more in coming weeks. Thanks for sharing knowledge with us.
Perl Weekly Challenge: Week 316
Another comeback from holiday as expected with a bang. Enjoy Perl and Raku together in one place.
Regular Sequences
Serious regex in play, so take your own time to explore. The story made it easy to follow, well done.
coming back from PostgreSQL OpenDay
Looks like, this is the comeback week. Another member back in action, only Raku this week. Keep sharing the knowledge.
Perl Weekly Challenge 316
Ideal playground for our in-house one-liner master. I found the regex very special. I have to try it this, very tempting.
Ring-a-ring-a-roses or a sack race?
Here is the power of CPAN making the solution compact and easy to follow. Keep it up great work.
The Sequence Goes Round and Round…
Here is the musical blog post for you, highly recommended. What a comeback, thanks.
Tricky characters
Innocent unless proved guilty approach, why? DIY to find the reason.
The Weekly Challenge #316
Simple for-loop and substr is what we need to get the job done, short and sweet, well done.
Circular Reasoning
Good old friend, Javascript, made it to the discussion table. I wonder how do you test it?
Sub circular
I love the color scheme of Python code in the post. It makes it very attractive. Two straight forward solutions in Perl and Python.
