Your project's README stinks. Let's make it better, together!Your project's README on Github is your project's landing page, your one chance to land a solid first impression with a new user. So why are so many READMEs so boring? With minimal effort, you can make a lasting impression that win over users who might otherwise move on to another project instead.

Jason Crome will show you some techniques for making an eye-popping README for your project, using Request Tracker, Dancer, and other popular projects as models for what can be done. By the end of this short talk, you'll be able to take your project's README to the next level and set yourself apart from other open source projects.

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.

In recent years we've seen an explosion of powerful web technologies in Perl not at the least due to the creation of the PSGI specification.

Plack provides the Plack::Middleware class that makes the process of modifying the response easier, and along with Plack::Util helps us deal with the slightly more complex cases where there's a callback for a response from our inner class:

Plack::Test

Another great thing about abstracting away the actual webserver that our PSGI application is talking to is that we don't actually have to have a real webserver at the outer layer at all! If we just want to test our application we can do this in process by just sending input to the anonymous subroutine and examining the return values.

Moving from an old CGI application to Plack/PSGI in CGI mode and to running it in the Starman application server.

Goal - Mission Statement

Help individual people and teams to improve their skills and processes so they can create better quality software faster while they enjoy their work more. So in the end they will have a better job. All this while I enjoy my work and make enough money to sustain my life.

Many introductions to Rust already exist. Most of them are aimed at C++ programmers. That makes sense, but lots of folks are coming to Rust from other languages now.

My current1 day job is mostly Perl. It occurred to me that an introduction to Rust aimed at people who already know Perl could be useful.

Join us for the first day of TPCiG, in the cPanel Theatre.

How should we deal with numbers vs strings in JSON? Perl doesn't care!

Cpanel::JSON::XS::Type to the rescue! I'll explain its motivation, show usage and possible traps, describe the implementation, and discuss related problems in other modules.

Some time ago we had the glorious idea to deploy our code into the cloud. The Google cloud, to be specific. This means we had to learn Kubernetes (to manage and scale our apps), Docker (to pack the apps into containers), gitlab CI (to automate the deployment process) and a whole lot more.

In this talk I'll explain the basics of Kubernetes, Docker and CI; describe how to make your app code cloud ready; and show you our current deployment pipeline.

Be prepared to see Perl, YAML, bash, Makefiles and other horrors required for smooth sailing in the clouds.

From its start, Perl comes with most (Unix) core operating system trickery like forks, events and signals. So, you can implement real performing daemons for interesting tasks.

We will get into various features which show how straight-forward it is to implement an Apache-like webserver, with VirtualHosts, proxies, etc.

But we start by discussing many options how to set-up servers: processes, event-loops, and so on... before we reach to HTTP-servers processing requests.

Mojo one-liners are just Perl one-liners. You will use -E (or -e) to write the program. You might use -n to loop over input, or -p to do the same while printing $_ after each item, just like normal one-liners.

To get the extra Mojo goodness, add -Mojo. The name itself is a cute hack. Since -M is what loads a module on the command line, the module name is therefore ojo.

Tom's Unicode Scripts So Life is Easier

Santa's elf had a problem. He had to write a presentation very fast and show it to a bunch of new elves. The email assigning this to him was sent by Santa himself. The elf started to look on MetaCPAN and found this module: Mojolicious::Plugin::RevealJS

New, powerful features have recently been added to PDF::Builder and PDF::Table, enabling faster and easier high-level generation of PDF documents. The versions are respectively 3.025 and 1.005, and are available on CPAN.

As well as the ability to "pour" text into a document's defined page areas, and have it flow easily over pages, this new version also enables high level text formatting with markup languages, as well as much-enhanced font management. The markup supports Markdown (via Text::Markdown) and a large (and growing) subset of HTML/CSS, as well as simple paragraphs-only markup, and for the first time can be used to format cells in PDF::Table. This is far from the final version, as many improvements are in the pipeline for this functionality, and are expected to be released over the coming one to two years. These will include, among other things, proper word hyphenation and probably some form of paragraph shaping, such as Knuth-Plass. The full list (at this time) is at https://github.com/PhilterPaper/Perl-PDF-Builder/issues/195 .

With my open source work, I’ve historically taken an approach which relies more on integration... Tagged with perl, tdd, test2suite.

Test2::V0 provides a good base to work with, so we add that to our project’s requirements list straight away.

We’ll round that out with:

Test2::Require::AuthorTesting to skip certain tests when run on the end user’s machine, and require the AUTHOR_TESTING environment variable to run. This is useful for tests which are very slow or require a highly specific environment to run in.
Test2::Require::Module to skip certain tests when optional modules are unavailable.
Test2::Tools::Spec to better structure our unit tests.
Test2::Plugin::BailOnFail for when your tests simply cannot carry on. Use sparingly.
