Hi Everyone.

I am learning from the book "Learning Perl" and so far the journey is thankfully going great!

One thing noticed about Perl is that although the developer community here is smaller than other mainstream languages it feels very tight-knit. Is that just me or were you also drawn to Perl because of the strong community responsiveness to each other?

UUID::Tiny has a weird way of getting a random 32bit integer using 2x random 16 bit integers bitwise OR'd together:

sub _rand_32bit { _init_globals(); my $v1 = int(rand(65536)) % 65536; my $v2 = int(rand(65536)) % 65536; return ($v1 << 16) | $v2; }

Anyone know why you would do this instead of just: my $rand = int(rand(2**32));? Also why the modulus, isn't it redundant?

This year is the 25th Perl Advent Calendar. It's time to start planning what you'd like to write about, or throw some ideas for what you'd like to read.

It all happens through the Perl Advent GitHub repo.

TWC 277: Strength Uncombined

https://blogs.perl.org/users/bruce_gray/2024/07/twc-277-strength-uncombined.html

I have a Mac M1 chip laptop.

While I have managed to install a couple of modules, most fail to install.

I tried perlbrew, but that was a struggle to even get it to install perl itself, but when it was installed it wasn't working the way I needed it to.

Just wondering if I am missing something with CPAN or if this is an issue because it's an M1 chip?

How to use perl v5.40's boolean builtins in Mojo::Pg queries

https://blogs.perl.org/users/karjala/2024/07/how-to-use-perl-v540s-boolean-builtins-in-mojopg-queries.html

The final installment in the series:

"The-Quest-For-Performance" from my blog Killing It with #perl

Discussing #python #numpy #numba, #rstats #openMP enhancements of Perl code and #simd

Bottom line: I will not be migrating to Python anytime soon.

Food for thought: The Perl interpreter (and many of the modules) are deep down massive C programs. Perhaps one can squeeze real performance kicks by looking into alternative compilers, compiler flags and pragmas ?

Perl Weekly Challenge 277: Strong Pair

https://blogs.perl.org/users/laurent_r/2024/07/perl-weekly-challenge-277-strong-pair.html

I would be interested to know why you chose Perl and how long you have been using it and what for.

I have just returned to Perl after many years away, think decades rather than a couple of years. Consider me a noob as I've long forgotten anything I knew about the language.

I run a small home webserver, Apache on Windows 10 with Strawberry Perl, and recently started some projects starting with moving away with things like Google Analytics and going back to some old log analyzers such as AWStats, which is still being maintained, and W3Perl, which is not. Even more recently I have started using Ringlink.

Perl is still being developed, Strawberry, Active State, CPAN etc. but lost out to PHP and Python. Just like COBOL, I can easily imagine thousands of systems depend on Perl.

Perl Weekly Challenge 277: Count Common

Have been using the official MongoDB driver to date (https://metacpan.org/dist/MongoDB) but its obviously EOL and now I can't get it to work with perl v.540 on OSX.

For those interested it fails on BSON::XS and I cannot force install either.

MongoDB-v2.2.2

Official MongoDB Driver for Perl (EOL)

^MetaCPAN

A couple of data/compute intensive examples using Perl Data Language (#PDL), #OpenMP, #Perl, Inline and #Python (base, #numpy, #numba). Kind of interesting to see Python eat Perl's dust and PDL being equal to numpy.

OpenMP and Perl's multithreaded #PDL array language were the clear winners here.

Hello all. I installed Perlbrew to try it out using Perl modules without admin rights. My machine is Linux EOS. When I run a simple perl script it gives error Cant locate Modern/Perl.pm in \@INC. How do I make Emacs know that I am using perlbrew and not system Perl? Or how do add the perlbrew PATH to global \@INC? I also have setup Devel::PerlySense inside Emacs following the module documentation. I installed some modules using cpanm client. I'm new to Perl and Emacs and sometimes I'm lost n doesnt know what I'm doing lol 😀 Appreciate your pointing me to the right direction. Below are some log details:
