“People still use Perl?” Twenty Years of Making a Living With a Dead Language
A little over twenty years ago, Ruth Holloway wrote her first Perl script, and the person who taught her how even said then that Perl was a “dead” language. Perl’s an awfully lively zombie! Travel along with Ruth through two decades of the joys and sorrows of making a living with Perl.

In 2001, Ruth learned Perl as a way to wrangle the pipe-delimited output of a proprietary database tool. Since then, she’s never stopped learning new things from Perl, working in multiple open and closed-source communities using the language. In this humorous, nostalgic, and thought-provoking talk, we’ll explore some the best—and the worst—that Perl has to offer. She’ll show that Perl can continue to have a life far past the time when so many say it is “dead,” and explore how we as current practitioners of the language can help encourage and mentor a new generation of Perl users and maintainers.

Sudoku by Regexp, part II
Elevator Pitch
Sudoku! Windoku! Battenburg! Anti-Knight! Renban! German Whispers! …
And a Regular Expression wizard who solves them with arcane incantations.

Description
The first time YAPC was in Houston I showed how we can solve Sudoku puzzles using regular expressions.
Now that YAPC^WTPC is returning to Houston, it is time to revisit the 2007 talk. The world of Sudoku has moved on. Beside regular Sudokus, there are nowadays a lot of variant, using additional rules. For those who missed part I back in 2007, we will first show how to solve normal Sudokus using regular expressions, then focus on several variants, and generate regular expressions for them as well.
Disclaimer: do not try this at home, unless supervised by a regular expression wizard.

Supercharging Perl
Elevator Pitch
Can Perl possibly be faster? YES! How to improve the performance of your Perl scripts using mostly minor changes to your code. Performance often comes at a cost–more memory! So we’ll also look at techniques to shrink your Perl script/module footprint.

Description
This is a followup to my “Perl Optimization Tidbits” talk in 2018. Then we looked at many minor performance differences in expressions like ++$x vs. $x++, “abc” vs. ‘abc’, etc. We go into more depth with more comparisons, but also cover larger strategies–algorithmic, structural, and other optimization techniques to get the best performance. In addition we’ll look at various ways of profiling your code so you can see where your slow places are. Some of these techniques and strategies can be applied to improving performance of other languages as well.

NewFangled: Bringing NewRelic to Perl with Alien and FFI Technology
Vendors aren’t rushing to write Perl bindings for their fancy new libraries anymore, but Alien and FFI can help make it easier for Perl developers to do it themselves. I’m going to talk about how I used these technologies and built some new ones to bring NewRelic into the Perl ecosystem.

This talk will describe the process in detail of taking an external non-Perl library and making it work in the Perl ecosystem using Alien and FFI::Platypus. Most software vendors today are no longer providing bindings for Perl anymore. For example at Fastly we wanted to monitor one of our internal Perl applications using NewRelic. The only existing Perl bindings were based on a beta product that had never been supported, so I set about writing my own. I will show how I did this by leveraging existing technology, as well as writing some new tools for handing C structured data. I will also cover some other FFI library bindings and in the tradition of Open Source show how my NewRelic bindings were extended by others.

Introduction to Perl Data Types
Data types are hints to a computer language, telling the language’s interpreter or compiler how best to allocate resources and optimize performance.

We will introduce the type system provided by the Perl compiler, and the many benefits of utilizing Perl data types.
Let’s explore types together!

The Perl interpreter itself is written in C, and implements data types for its own internal use, including:
  • IV, integer value
  • NV, number value
  • PV, pointer value AKA string
  • AV, array value
  • HV, hash value
  • SV, scalar value
  • RV, reference value
The Perl interpreter does not provide programmers with access to these pre-defined types, and instead it encourages us not to use data types at all.
Perl does allow programmers to create user-defined data types, but none of the (numerous & incompatible) data type systems actually utilizes the underlying C data types implemented in the Perl interpreter.
The Perl compiler finally provides developers with direct access to real C data types and their C++ equivalents.
Upgrade your Perl, start utilizing data types today!

Perl T20 - The last minute challenges saved by perl
T20 is a buzz word in cricket world, which represents the short format of the game. Especially the twists in dying minutes, makes it more challenging. Similarly in software, the last minute changes end-up in challenging targets. Lateral thinking is vital in winning those moments. We will share few.


Generally, need is considered the mother of invention. True to that, during tight targets we always ended-up a lean solution that we did not think of or ignored for long. Those challenging & committed times; our mind transcends in all direction, breaks traditional barriers to get a solution. Those times we often felt of a partner, travels in our wave length will be a great gift & boost to accomplish it. In our case, perl’s flexibility & multifaceted character given us the power to solve the non-linear challenges.
Some of it: 1. A data munging operation to capture the missed business leads from 1000s of email 2. Implementing an out-of the box outgoing email capturing in a shared hosting account 3. Producing demo document pdfs in 1/10 of the time for a sudden & surprise business proposal 4. Updating a product image based website with 1/3 of resource with automation of image naming, image resizing, image uploading 5. Revamping a website after 15 years with 1000 of images, gallery update automation 6. Chinese Cyber Incursions & counter actions 7. Website Migration between different CMS engines
Perl’s way for every skill level given way to implement the solution like chasing a tough score game in an incremental way with ups and downs. Most of the scripts now in open-source. We will share the implementation cases and I hope it will give an acumen for similar non-linear & constraint scenarios.

Modern Approaches to Ancient Perls
Many of us are tied to really old Perl distributions, for a variety of reasons. Just because you’re using Perl from 1998 doesn’t mean you have to develop software like it’s 1998! This talk aims to help developers apply modern, maintainable approaches, even when you use 5.005;.

We’ll briefly discuss a bit of why people might be using ancient Perls, but mostly focus on some practical code examples. For example:
  • named captures were introduced in Perl 5.10, but you can get a lot of their advantages by putting a hash slice on the left side of a capturing regex
  • lexical filehandles were introduced in Perl 5.8, but you can use the Symbol module (in the standard distro!) to make your own lexical filehandles and dirhandles.
We’ll also talk about future-proofing (future resisting maybe..) your code. Maybe someday you’ll be able to update to a contemporary Perl release. If that day comes, you’ll be glad you:
  • added use-version pragmas: use 5.005;
  • use strict; Always. use warnings; except before 5.8. Then use #!perl -w

This will be the fourth year doing this presentation. It is structured like a game show–a bell when the answer is right, a buzzer and red light flashes when the answer is wrong. But it doesn’t matter because everyone wins a prize. Questions cover topics having anything to do with Perl. Some questions are fluff and don’t really matter while others are tricky questions that everyone needs to know. It is always fun, informative, and worthwhile.

This talk is meant to serve as a primer for the later in the conference that discusses using OpenMP in your Perl code. It covers: what OpenMP is, what it can do, and why Perl programmers might care to consider it for your next computationally intense application. It covers the basics of OpenMP in C code; including what it does, and how to use it - parallel constructs, compiling, and running the code.

raku::Dan - Re-Inventing the DataFrame
Elevator Pitch:
The explosion in Data Analytics and Data Science applications has been driven by Python and its library modules such as Pandas and Polars. This talk is about re-inventing DataFrames using a raku-centric approach to fundamentally improve architecture, code concision and manipulexity.


Description:
As raku matures, we need useful basic eco-system modules to bring the unique strengths and cultural style of raku to real-world use-cases.
raku::Dan (Data ANalytics) is a new raku module family (also Dan::Pandas and Dan::Polars) that offers top level Raku-oriented data structures for Series and DataFrames. The thinking is:
  1. we need a Raku-esque way to do the analytics basics - Series and DataFrames
  2. much has been inspired by Python Pandas (not least for good interworking)
  3. we can draw from many Raku native capabilities (accessors, types, hypers, laziness, pipes, sort, grep, splice, etc.)
  4. Pandas suffers from featuritis (Pandas has 422 object methods, plus 50 or so module methods and raku offers a fresh start
This talk will describe the raku::Dan family - design considerations, focus & roadmap and unique differentiators - with hands on examples of Data Munging in Raku and interworking with Python Pandas via raku Inline::Python.

Why Do Programmers Love Rust?
Rust is an exciting new programming language that aims to make high-performance systems programming safer and easier. Come to this talk to learn what Rust is all about.

Rust is a low-level language that has been voted the most-loved programming language in the Stack Overflow survey for six years straight. This talk aims to show you why.

If you’ve programmed in Perl for long enough, you’ve probably needed to reach for a faster language from time to time, like C or C++. And if you’ve done that, you also know why so many people prefer high-level languages like Perl to low-level languages like C or C++!

Rust brings several interesting features to low-level programming. Rust uses its borrow checker to enforce memory and thread safety without a garbage collector, and with no need for manual malloc and free calls. It also features an advanced type system that requires you to explicitly handle errors, eliminates the billion-dollar null pointer mistake, and allows you to express complex constraints that can be enforced at compile-time through type definitions.

This talk will cover some of the most interesting features of Rust, complete with code examples. There’s not enough time to teach you how to code in Rust, but this talk will help you decide whether learning Rust is something that you want to do.

Fast perceptual image hashing with Perl
Talk slides, images & code used: https://github.com/dkechag/ImagePHash-Talk

This talk will take you through a novel Perl implementation of perceptual hashes for “similar image” searches. I'll start with the basics, if you don't know what a Discrete Cosine Transform is, you'll find out with a visual demo - no math required (although math is always encouraged!). After DCTs and p-hashing basics, I will go through the implementation’s new features that make it efficient and easy to integrate with our large MySQL-based image database.


At SpareRoom, the world’s largest roommate finding service, we handle tens of millions of images, mostly of customer rooms/properties. When tasked with adding an internal ability for a “similar image” search, I first looked at existing solutions and found out that some did not work as expected, while others were either slow or required changes to our infrastructure (mainly Perl, with the data - including the image index - on a large MySQL database).
In the end, I went with a solution initially based on Image::Hash, but with p-hashes reimplemented to fix collision issues and add speed (over 10x faster than pHash.org’s equivalent DCT-based hash). Then, I added features such as support for mirroring, as well as “index/reduced” hashes, in order to effectively use MySQL indices (and thus easily fit in our existing setup).
After an intro to the theory behind the DCT and perceptual hashes in general, I will discuss the abilites of this implementation and the experiences from developing and using it. The module will be released to CPAN before my talk, although the XS part responsible for the fast DCT calculation has been available for a while as Math::DCT.

Raku has powerful support for breaking code into modules. In this talk, the basics of module creation will be discussed —what to include where, creating a META6.json file, controlling exports— so that even beginners can feel comfortable creating their own personal modules. For more advanced users, an overview of the Fez ecosystem will be presented with a how-to on using it and submitting modules.

CPAN, Dist::Zilla, and you
Do you have Perl modules that you want to share? Dist::Zilla is a great tool to do it. Come learn how to become a CPAN author, and share your code with the world!

The CPAN repository is a bit of a black-box for most users—ask for code, you get it, done. But if you’re wanting to add something to the repository, you need to learn how. In this talk, Ruth walks through the basics of becoming a CPAN author, from PAUSE accounts, to structuring your code, to uploading using Dist::Zilla, using some common plugins to assist the process.

Grammatical (dis)agreement: Mixing grammars in Raku
Elevator Pitch:
In this talk, I will discuss ways a programmer can use an established grammar (e.g. JSON::Tiny) inside of another grammar that they are writing. Why rewrite the rules when you can steal them from someone else?

Description:
This talk will present a problem case (wanting to use an extant grammar inside of another) and discuss several different solutions for it. The process isn’t entirely straightforward, and each method had advantages and drawbacks which will be mentioned and demonstrated. Finally, ideas for writing grammars/actions that play nicely with others will be discussed.

The Perl Navigator: code intelligence for any editor
Language Servers provide language intelligence features such as autocomplete via standardized protocol that can be consumed by different editors. This allows developers to use their preferred code editor and still receive the same high quality code intelligence as any other editor. In this talk, I’ll go through the basics of the Language Server Protocol as well as the architecture of the Perl Navigator, a new language server for Perl.

The Perl Navigator supports syntax checking, code navigation, autocompletion, hover, Perl::Critic and Perl::Tidy. It works on Linux, MacOS, Windows, and can be used in Visual Studio Code, Vim, NeoVim, Emacs and Sublime Text, and supports back to Perl 5.8. I’ll discuss the architecture of the Perl Navigator, including symbol table parsing and how it leverages the B:: compiler backend. I’ll also discuss the roadmap for new integrations and contribution opportunities for those interested. A simplified Raku Navigator exists as well for those who need Raku support.

Can Perl Create Video Games?
IntroWe all know Perl created the original CGI scripts in the early WWW.
We’ve all seen Perl database code running on a cloud server.
We’ve each written dozens (if not hundreds) of Perl scripts & utilities.
But can Perl be used to create something as common, yet as complex, as a graphical video game?


DescriptionMany (if not most) video game engines are written using high-performance languages such as C or C++.
This is especially true for graphical video games, which often are among the most computationally demanding of consumer software applications.
We are faced with the question: can Perl be used to create high-performance, high-quality graphical video games?
Recent advances in Perl optimization and performance technologies have finally brought this goal within reach.
Review the general components of video game development, and how they can be implemented in Perl:
  • 3D Graphics Rendering
  • Physics Engines
  • Non-Player Characters
  • Gameplay Genres
  • Storyline & Plot Development
Grab your favorite joystick, dust off your old sprites, and let’s make some games!

Command-line Filters - Time to Shine
Filters are the basic tools of command-line data munging. `grep` `head` `cut` `sort` `uniq` `wc` `diff`, pipes + redirects, intro + advanced tips. Why stop there? You can write your own. Perl, Raku, & Python have strong support for writing filters. Existing code often works better when refactored as a filter.

These techniques are my bread-and-butter for exploratory programming and data analysis, and include a few of my best tricks.

The Database Dance: DBIx::Class and Dancer2 treachery to increase web application performance
Writing web applications with DBIx::Class and Dancer2 is super-easy. Learning how to make them efficient takes a little longer. Come see some of the things that Ruth has learned—and created—that make these apps faster and easier to maintain.

Writing inefficient applications is startlingly easy to do; some of my early Dancer2 work shows it! In this talk, we’ll discuss ways to structure queries and code to speed things up, and show some of the tools that are available for Dancer2 and DBIx::Class that make maintaining these systems just a bit easier.

State of the Art: Perl and Multithreading via OpenMP
Due to the overwhelming interest in the 2021 lightning talk on the same subject, we will discuss the current options available for including OpenMP into your Perl programs for computationally intensive applications. No XS will be harmed during this talk. Modules discussed include,
  • OpenMP::Environment
  • Alien::OpenMP
  • Inline::C
Because OpenMP is meant to be “environmentally aware”, it presents some challenges; these challenges and their solutions will be discussed. The ultimate goal of this talk is to promote the fledgling Perl-OpenMP effort and encourage exploration on the best ways to present SMP programming interfaces within Perl programs.

Keep on turning: Going even further on wheels we didn't re-invent.
Our Friends the Utils was written in 2012, how time flies when you’re having Perl! Both the language and modules have been updated in a variety of ways, leaving us even more things to not re-invent for creating clean, usable code.

Scalar::Utils & List::Utils were great when they came out, then we got List::MoreUtils. The result was a whole lot of Perl code nobody had to write. The last decade has seen advances in Perl and the modules, giving us even more things not to re-invent. Catch is that too many people don’t know about these or have time to keep up on how they change. This talk looks at some changes in Perl, advances in the modules, and ways to use them for creating concise, readable, fast code.

Playing nice with others using the new COERCE protocol
Elevator Pitch:
Part history lesson, part practical talk. Learn the origins of coercion in Raku from the very beginning and discover how the COERCE protocol came to be and how it can be used in modules today.

Description:
This talk will begin by looking at the original synopses and how coercion was (and was not) eventually implemented. It will then look at the more recent history and the reason a new system was needed. Lastly it will provide advice for developers on how to take advantage of the protocol to increase compatibility and reduce code noise.

Content Audit and Gap Analysis of Perl's Core Documentation
This talk is based on the six-month project completed under Season of Docs 2021. The aim was to identify the major problems in Perl’s existing documentation and to devise a strategy for its improvement. The project was completed successfully with a clear roadmap for the future.

Perl – an open-source, general-purpose programming language – has a lot of documentation, organized in the form of articles, FAQs, and web pages. Such detailed documentation, if not organized well, is overwhelming and frustrating for the audience. With over 100 core documentation pages, the users can easily get lost in the volume of the information, resulting in a bad user experience. This project aimed at resolving these issues and improving the structure of Perl’s core documentation. The project, divided into four major phases, was completed over the course of six months under the Google Season of Docs 2021.
  1. Content Audit It all began with a comprehensive content audit. Every single document in Perl’s core documentation was thoroughly analyzed to identify the shortcomings of the existing documentation and the areas for improvement. A content audit spreadsheet was created, recording the traits of individual documents including but not limited to the date when a document was updated, the intended audience, and cross-referencing. The audit served as a first step in improving the documentation.
  2. Gap Analysis The second phase was that of Gap Analysis, where insights from the Perl community came in handy. Individuals participated in informal user research and shared their feedback on the existing documentation. This gap analysis made the target audience a part of the project and provided clarification on the smaller, task-based, projects that could then be created to help improve the overall documentation.
  3. Information Architecture Content audit and gap analysis, followed by discussions with the contributors at Perl, identified the ways in which the documentation could be made more useful and usable. In order to give a structure to the documentation, it was essential to improve the existing information architecture (IA). A new IA was proposed, which then went through a series of revisions, to incorporate the needs of the users in the structure and presentation of Perl’s core documentation.
  4. Roadmap for the Future The final phase of the project was to devise a roadmap for the future of the documentation. This roadmap brought the findings of content audit, gap analysis, and information architecture together. Specific tasks and projects, along with possible limitations, were created and shared with the contributors of Perl to help improve the documentation in the days to come.
Quality documentation is imperative for the success of an engineering tool like a programming language. The existing documentation of Python, Prettier, and ESLint is a case in point. This project brought technical communication principles to documentation practices in the engineering discipline. The suggested improvements to Perl’s documentation will add value to the user experience by providing better navigation, ease of access, and a useful structure. The findings of this project highlight the best practices in engineering communication, serving as an example that documentation teams can follow in the future.

The NEXT steps to simplify EVERY::LAST class you write with mro.
Elevator Pitch
NEXT provides some nice features but was written long before mro, which has some nice features but lacks EVERY & EVERY::LAST. This talk describes why you’d care, how to graft mro into NEXT, and how mro::EVERY makes it easy.


Description
NEXT and mro provide useful features but not play nice together: NEXT uses its own depth-first search and cannot use “c3”. Unfortunately, mro is missing to of the more useful features of NEXT: the EVERY & EVERY::LAST pseudo-classes for automatic cross-class dispatch up and down the inheritance tree. This is especially painful because c3 makes so much more sense but modules that use the pseudo-classes can’t convert.
The pseudo-classes simplify cooperative operations like construction & destruction by passing a call up or down the inheritance stack to each class implementing the required method. This saves every class from having to knowingly participate in the process – and saves us all from people leaving it out or doing it wrong – and really simplifies creating generic base classes that are easy to use.
This talk looks at mro::EVERY and how the pseudo-classes were implemented using mro and what they offer, also how we can graft mro into NEXT, and how they can be used to simplify your life.

Come collaborate on making Raku's great documentation into something truly stellar.

We have room and time to:
* Start newcomers on how to review and edit the existing docs
* Hear complaints, and turn them in actionable Github Issues.
* Complete and beta-test some new documents that deep-dive, e.g. on sorting.
* Discuss face-to-face some long-term issues that had been unresolved in email

Current plans are to also have remote collaboration with prior contributors who cannot attend in person.

Juggling Patterns In Perl
Intro
Juggling patterns are described by a mathematical language named Siteswap, with names such as:
  • 333 AKA “Cascade”
  • 4444 AKA “Fountain” AKA “Can’t You Juggle More Than 3?”
  • 55555 AKA “5 Cascade” AKA “Can’t You Juggle More Than 4?”
  • 51 AKA “Shower”
  • 52515 AKA “Passing The Baby”


DescriptionI’m the founder of Circus Texas, and I’m friends with some of the guys who invented Siteswap notation in 1981.
In this presentation, you will see both the software and real-life on-stage versions of several Siteswap patterns, including:
  • 333 AKA “Cascade”
  • 4444 AKA “Fountain” AKA “Can’t You Juggle More Than 3?”
  • 55555 AKA “5 Cascade” AKA “Can’t You Juggle More Than 4?”
  • 51 AKA “Shower”
  • 441 AKA “Half-Box”
  • 531 AKA “Tower”
  • 52515 AKA “Passing The Baby”
Free juggling lessons will be provided after the talk!
