Hello friends,

Over the last 7 or so months I have worked with a very small team to build a performance monitor for the modern Perl web-application ecosystem. As of today, the project is now available to everyone via the free-tier only, later however, (a month or so) we will be opening up our priced tiers to business users who will most likely need more from the application.

Please feel free to check it out, and I look forward to hearing feedback!

Good afternoon, all. I have a Perl script that connects to a bunch of REST-based services via LWP::Simple. I'm running on MacOS (Perl v5.30). One of these services moved to be SSL-based. I've been struggling to find an appropriate library to use for SSL with Perl. These libraries require a certain amount of certificate management on my Mac -- and integration with Perl via environment variables or such -- and the instructions are generally sparse/obtuse. Can anybody help with this? I'm not looking to do anything particularly fancy. Just call a REST service via HTTPS. Thanks in advance for your help.

We need to be able to work with parquet files. It is a must.

For anyone cares a solution could me a native DuckDB driver. It is a pitty we do not have it.

Anyone able to help? Pulling my hair out.

I'm getting an SSL failure , and I can’t figure out what isn’t migrated properly from the perl setup

'auto_upgrade' => 1 }, 'Mojo::Asset::Memory' ) }, 'Mojo::Content::Single' ), 'error' => [ 'IO::Socket::SSL 1.75 required for TLS support' ], 'finished' => 3, 'state' => 'finished'

It seems to be using the same exact local Perl config but after a long time chasing I have dumped out the module includes for perl and it is failing to load the file:

$VAR475 = 'IO/Socket/SSL.pm';
$VAR476 = undef;And $VAR161 = 'Net/SSLeay.pm';
$VAR162 = undef;

Whereas on the working (current, old server)It’s printing out correctly:

$VAR479 = 'IO/Socket/SSL.pm';
$VAR480 = '/var/home/tyeeapps/support.thetyee.ca/www/local/lib/perl5/IO/Socket/SSL.pm';$VAR161 = 'Net/SSLeay.pm';
$VAR162 = '/var/home/tyeeapps/support.thetyee.ca/www/local/lib/perl5/x86_64-linux/Net/SSLeay.pm';

I've reinstalled the revelant modules from yum at the system level, which shouldn't matter. As well as on the perlbrew install in play, and in Carton, which the app is using

relevant line of code:

https://github.com/TheTyee/support.thetyee.ca/blob/e5cf4fd189ea4256c7de2a4f91303908770125a7/app.pl#L705

which does:

$res

= $ua->post( $API

. 'subscriptions' =>

{ 'Content-Type' => 'application/xml', Accept => '*/*' } =>

$transxml )->res;

}

my $xml = $res->body;

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?

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 ?

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.

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.

With that said, whats the most appropriate alternative out there?

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.
