PerlOnJava now passes 239,400 tests from the standard Perl test suite — up from 150k just a month ago.
A big step toward full Perl 5 compatibility on the JVM.

For the first time in *years*, I've felt like blogging. I've been having so much *fun* writing #Perl, that I wanted to share some of it.
Hey, any Python experts want to help a Python newbie out? I've been hacking for decades, but I can't say I know Python best practices.
I'm working on github.com/Ovid/sqlitch-v2 (porting some Perl code to Python) and while it seems good to me (but very much alpha and a WIP), I don't know what I don't know. If there's anything obvious I've missed or is unpythonic, I would love to know.

Just asked ChatGPT 5.0 about the design of a particular tool that I was curious to write in #perl, despite the fact that Perl is probably not the best tool for the job.
ChatGPT suggested I use the Inline::Python module.
Sigh.

Heh. I added an example program to my latest #Perl arpeggiatiion release. And when I ran it, it played the theremin soundfont, that I forgot I have set. Oops. Haha.
Trippy dream sequence...
Ok. Previously, I linked to my new musical arpeggiation #Perl module. But it was deeply broken and I deleted the link.
But I refactored heavily, and now it's really smooth. So here it is again:
metacpan.org/dist/Music-Melodi…
Ha! 😁
#Perl projects that have survived mostly don't live-load modules from CPAN during Container/VM startup.* We have a tradition of caching the CPAN versions we tested with and deploying those with our deployments. This greatly increases the chances of being found in a Dev or Test environment and remedied before it gets to Production, vs. liveloading latest bugs from public repository with every container start as NPM.
* Docker manifests may pull CPAN live. I wouldn't recommend that !
So… npm keeps getting attacked, rubygems has been taken over from the top, I hope PyPI is not having problems…
How come CPAN (and, I guess, CTAN) has never made the news like that?
The worst I can remember is one guy who added a 1-line "phone home" HTTP call to his Makefile.PL, he was gently reminded that it's impolite to do that, and he stopped.
Is #perl just not a big enough target? And back when it would have been, "supply chain" attacks were not in fashion?
Bam! Another in my series of musical creativity #Python classes:
pypi.org/project/music-tonnetz…
Apparently, the nerdiest of chord transformations. Two of the apps on a synth module of mine have Tonnetz things. Ha 😁
This relies on my port of the excellent #Perl module, metacpan.org/dist/Music-NeoRie…

Importing Modules
Perl modules generally export functions/variables (most of them) or affect the lexical environment (pragmas, like strict/warnings) or are weird. We'll ignore the third kind. Symbol exporters usually affect the package they're used from, but there are some exceptions (e.g. builtin exports to the lexical environment). We'll ignore lexical exporters as well.
Here are some of the ways you can load modules in Perl:
use Some::Module;gives you the "default" behavior/exports, whatever that is for a given module.use Some::Module "list", "of", "args";passes the arguments to the module to do whatever. For symbol exporters this is normally the list of symbols you'd like to import.use Some::Module ();(an explicit empty import list) loads a module without importing anything.require Some::Module;also loads a module without importing anything, but at runtime, not compile time.{ use Some::Module; }imports package symbols, but inhibits pragma effects. (For example,{ use Moose; }gives you helpers likehasorextends, but does not turn on strict/warnings.)package My::Package::_Dummy; use Some::Module; package My::Package;provides the opposite effect: It enables lexical effects, but diverts exported symbols to a different package.

A memorial, and burial, for [Matt S. Trout a.k.a mst] will be held at 14:00 on Wednesday 30th July in the Much Hoole Woodland Burial Ground.
Dammit, mst. I owe you. You welcomed me to the community, you inspired me, you made me laugh, and you nudged me in the right direction when I said some dumb shit. You didn't even permaban me when I flooded #perl with a kilobyte of combining Unicode characters. I still can't believe you're just ... gone. I wanted to talk to you again.
Well fuck. mst had a terrible habit of uh opening his mouth and letting words come out. But very smart, did his damnedest to be kind, usually admitted his failures, and a hell of a lot of energy. A loud, abrasive cornerstone of the #Perl community.
Sounds negative, but no. I'm just acknowledging his issues while saying with full heart that I've missed that fucker and now I'm mad I have to keep missing him.

Are you still using the 2-argument open?

I have also uploaded a Dist::Zilla plugin to #CPAN for testing code against mixed Unicode scripts.
I’m looking for work as a senior software #developer. I have a full-stack #WebDev cert, 16+ years #Perl back-end experience, proficiency in multiple other #programming languages.
Databases? Sure, relational *and* NoSQL. Ci/CD? Have done, want to do more. I like working with others, either here in #Houston or remotely across the US.
I’ve been hacking code since the #Commodore PET days. I can certainly delight your customers, whatever your stack.

I wrote a post using #PDL for extraction of line features from images using a Hough transform. Hopefully, it shows PDL's capability for working with ndarrays (even though this is just 2D in both the image and parameter space).
