I've been trying to debug an issue for 3 days now, am getting nowhere, and am about to headbutt my laptop. If anyone's done any heavy lifting with Net:DBus then, for the sake of my laptop, I'd really appreciate the help!

Problem description: I have a hash table with a bunch of keys. The values relating to those keys are of different types (as in, I've cast them to dbus types). So:

my $testhash = {}; $testhash->{"xesam:albumArtist"} = [dbus_string("Tom Waits")]; $testhash->{"xesam:album"} = dbus_string("Mule Variations"); $testhash->{"xesam:trackNumber"} = dbus_int32(1); $testhash->{"xesam:artist"} = [dbus_string("Tom Waits")]; $testhash->{"xesam:title"} = dbus_string("Big in Japan"); $testhash->{"mpris:artUrl"} = dbus_string("file://mnt/storage/Music/mp3/Tom Waits/Mule Variations/folder.jpg"); $testhash->{"mpris:length"} = dbus_int64(64182857); $testhash->{"mpris:trackid"} = dbus_object_path("/0"); $testhash->{"xesam:url"} = dbus_string("file://mnt/storage/Music/mp3/Tom Waits/Mule Variations/01 - Big in Japan.mp3"); 

dbus_method("ReturnDynamicHash", [], [["dict", "string", ["variant"]]], $IFACE); sub ReturnDynamicHash { my $self = shift; print "Object: ReturnDynamicHash called.\n"; my $return = {}; my @keys = keys(%{$testhash}); my $count = scalar(@keys); if ($count) { foreach my $key (@keys) { $return->{$key} = $testhash->{$key}; } } return $return; } 

% dbus-send ....... .ReturnDynamicHash array [ dict entry( xesam:trackNumber variant int32 1 ) dict entry( mpris:trackid variant /0 ) dict entry( xesam:albumArtist variant array [ Tom Waits ] ) dict entry( xesam:album variant Mule Variations ) dict entry( mpris:length variant int64 64182857 ) dict entry( xesam:url variant file://mnt/storage/Music/mp3/Tom Waits/Mule Variations/01 - Big in Japan.mp3 ) dict entry( mpris:artUrl variant file://mnt/storage/Music/mp3/Tom Waits/Mule Variations/folder.jpg ) dict entry( xesam:artist variant array [ Tom Waits ] ) dict entry( xesam:title variant Big in Japan ) ] 

dbus_property("StaticHashProperty", [["dict", "string", ["variant"]]], "read", $IFACE); sub StaticHashProperty { print "Object: StaticHashProperty accessed.\n"; my $return = {}; my @keys = keys(%{$testhash}); my $count = scalar(@keys); if ($count) { foreach my $key (@keys) { $return->{$key} = $testhash->{$key}; } } return $return; } 

From the dbus-send client I get

Error org.freedesktop.DBus.Error.NoReply: Remote peer disconnected 

dbus[93409]: Array or variant type requires that type array be written, but object_path was written. The overall signature expected here was 'a{sas}' and we are on byte 4 of that signature. D-Bus not built with -rdynamic so unable to print a backtrace Aborted (core dumped) 

Since the Method works I know Net::DBus can handle these sorts of return values, but for some reason, as a property, it just isn't working. I also know that other applications do implement this interface, including this Property, successfully, so I know this isn't a limitation of DBus.

I've been looking at the code in Net::DBus that handles serialization, assuming there must be some difference between how Properties and Methods are handled, but can't see anything obvious.

Anyone? Any idea? Literally anything at all? Thank you!!!!!

The following is a quick ramble before I get into client work, but might give you an idea of how AI is being used today in companies. If you have an questions about Generative AI, let me know!

The work to make the OpenAI API (built on Nelson Ferraz's OpenAPI::Client::OpenAI module) is going well. I now have working example of transcribing audio using OpenAI's whisper-1 model, thanks to the help of Rabbi Veesh.

Using a 7.7M file which is about 16 minutes long, the API call takes about 45 seconds to run and costs $0.10 USD to transcribe. The resulting output has 2,702 words and seems accurate.

Next step is using an "instruct" model to appropriately summarize the results ("appropriate" varies wildly across use cases). Fortunately, we already have working examples of this. Instruct models tend to be more correct in their output than chat models, assuming you have a well-written prompt. Anecdotally, they may have smaller context windows because they're not about remembering a long conversation, but I can't prove that.

Think about the ROI on this. The transcription and final output will cost about 11 cents and take a couple of minutes. You'll still need someone to review it. However, think of the relatively thankless task of taking meeting minutes and producing a BLUF email for the company. Hours of expensive human time become minutes of cheap AI time. Multiply this one task by the number of times per year you have to do it. Further, consider how many other "simple tasks" can be augmented via AI and you'll see why it's becoming so powerful. A number of studies show that removing many of these simple tasks from people's plates, allowing them to focus on the "big picture," is resulting in greater morale and productivity.

When building AI apps, OpenAPI::Client::OpenAI should be thought of as a "low-level" module, similar to DBIx::Class. It should not be used directly in your code, but hidden behind an abstraction layer. Do not use it directly.

I tell my clients that their initial work with AI should be a tactical "top-down mandate/bottom-up implementation." This gives them the ability to start learning how AI can be used in different parts of their organization, given that marketing, HR, IT, and other departments all have different needs.

Part of this tactical approach is learning how to build AI data pipelines. With OpenAI publishing their OpenAPI spec, and with Perl using that, we can bring much of the power of enterprise-level AI needs to companies using Perl. It's been far too long that Perl has languished in the AI space.

Next, I need to investigate doing this with Gemini and/or Claude, but not now.

Note, if you're not familiar with the BLUF format, it's a style of writing email that is well-suited for email in a company that is sent to many people. It's "bottom-line up front" so that people can see the main point and decide if the rest of the email is relevant to them. It makes for very effiicient email communication.

Hi all,

Nelson Ferraz has been working with generative AI for a while. I've started collaborating with him on his OpenAI modules. He wrote a module named OpenAI::API, but it required manually writing the code for all of the behavior. With the size of the OpenAI API, the rapid evolution, of said API, the birth of new models and the deprecation of old models, this approach turned out to be unmaintainable.

Thus, that module was deprecated in favor of Nelson's OpenAPI::Client::OpenAI module. Throw the 13K+ lines OpenAPI spec for OpenAI at it and it just works. Further, the module is pretty much a single Perl class rather than a bunch of hand-crafted code.

CPAN authors know it can be hard to keep modules up-to-date (mea culpa, mea culpa!) and this module is no exception. I need this module so I offered to collaborate and created a PR to update it to version 2.0.0 of the OpenAI spec. It now passes all the tests (for those wondering, you need an OpenAI key and it costs $0.04 USD to run the test suite).

In trying to build a Whisper pipeline for that, I found that I couldn't. There was a PR for Whisper support for the older module, but for the newer one, I can't figure out how to get it to issue a request with multipart/form-data support. I've noted the issue in the PR.

If anyone would like to see OpenAI support for Perl, we would dearly love to collaborate with you to make this happen.

Hi! Asking for a wisdom here...

We have a module that modifies signal handler $SIG{__DIE__} to log information and to die afterwards. Hundreds of scripts relied on this module which worked fine in perl 5.10.1.

Recently we had the opportunity to install several Perl versions but unfortunately a large number of scripts that used to work with Perl 5.10.1 now behave differently:

• Failed in 5.14.4: /home/dev/perl-5.14.4/bin/perl -wc test.pl RECEIVED SIGNAL - S_IFFIFO is not a valid Fcntl macro at /home/dev/perl-5.14.4/lib/5.14.4/File/stat.pm line 41
• Worked without changes in 5.26.3: /home/dev/perl-5.26.3/bin/perl -wc test.pl test.pl syntax OK
• Worked without changes in 5.38.2: /home/dev/perl-5.38.2/bin/perl -wc test.pl test.pl syntax OK

Many of the scripts can only be updated to 5.14.4 due to the huge jumps between 5.10 and 3.58; But we are stuck on that failures.

Was there an internal Perl change in 5.14 which cause the failures but works on other recent versions without any update on the scripts?

Cheerio!

My environment is perl/5.18.2 on CentOs 7

I'm trying to use a SWIG generated module in perl, which has a c plus plus backend. The backend.cpp sets an environment variable, $MY_ENV_VAR =1

But when I try to access this in perl, using $ENV{MY_ENV_VAR} this is undef.

However doing something like print echo $MY_ENV_VAR works

So the variable is set in the process, but it's not reflected automatically since nothing updates the $ENV data structure.

I'm assuming it may work using some getEnv like mechanism, but is there a way to reset/ refresh the $ENV that it rebuilds itself from the current environment?

Im working on a script to test using a jump server to reach remote devices.

I'm able to connect to the jump server using Net::SSH::Expect, however, I'm not sure how to then ssh to a remote device (network element).

Is there a way to create that ssh to the remote device inside the jump server's connection?

First things first, I am a data engineer but have little experience in Perl. I've been able to make some easy updates to scripts in the past but this one is a bit tougher.

I have been asked to update a Perl cgi web app that someone wrote ages ago that is used to view and manipulate text files. Currently it is hosted on server (X) and manipulates the files on that same server. However, we have to have backups/mirrors of the data on a dev server and another prod sever (Y). I.e., if I push the button to move the file to a different folder, it should do that on all three servers instead of just X. I added code to do this, referencing the additional servers with their UNC names, but I just get an error "No such file or directory" (which is not true). Googling has suggested that there may be an issue with permissions, but I can bring up the Y and DEV servers from a windows file explorer using the same path so I don't think that is necessarily the issue.

Example: Here we are trying to copy the file with a letter appended a given number of times. It works fine on the X server, its when trying to make it also work on the Y and DEV servers I get an error.

our $DIR_X = "\\\\serverX\\folder\\subfolder" ; our $DIR_Y = "\\\\serverY\\folder\\subfolder"; our $DIR_DEV = "\\\\serverDEV\\folder\\subfolder"; . . . }elsif ($query->param('action') eq 'split' && $query->param('fileNum') ne "") { my $fileNum $query->param('fileNum'); my $fileX=$DIR_X . "\\" . $fileNum . ".txt"; my $fileY $DIR_Y . "\\" . $fileNum . ".txt"; my $fileDEV = $DIR_DEV . "\\" . $fileNum . ".txt"; my $splitNbr = $query->param('splitNbr'); my @letters1("a".. "z"); for (my $i = 0; $i < $splitNbr; $i++) { my $FileNew_X = $DIR_X . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_Y = $DIR_Y . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_DEV = $DIR_DEV . "\\" $fileNum. $letters[$i]=.txt"; copy($fileX, $FileNew_X) or die "WARNING: copy failed: $!\n"; ---->>>>>ERROR AT NEXT LINE copy($fileY, $FileNew_Y) or die "WARNING: copy failed: $!\n"; copy($fileDEV, $FileNew_DEV) or die "WARNING: copy failed: $!\n"; }
