Turning humans into developers in a post Covid world

I'll be talking about hiring, training, mentoring and growing people to become (Perl) developers in an environment that's remote first, or hybrid. This talk is aimed at anyone who makes hiring decisions, leads or manages developer teams, or who mentors people at work or in an open source setting.It's been exceedingly difficult for many businesses to recruit new Perl developers. We all know this. It's getting harder. People retire or move on to different languages as the market evolves. But lots of businesses still luckily rely on Perl, and there is an appetite for more developers. Sadly, not many new ones are organically popping up. So we need to help.

In this talk, I will condense what I've learned in my 15+ years of experience hiring, training and retaining junior Perl developers. The market and the work environment has changed, and we're mostly all working remote now. This brings unique challenges and opportunities for hiring, training and mentoring, as well as working as a developer or a manager of developers in general.

We're going to look at how to attract, screen, interview and hire talented, motivated young people, how to get them interested in Perl, and how to mentor and train them up to be not just junior developers, but ultimately strong, independent thinkers and valuable contributors to your team, and sometimes the Perl community as well.

While my experience is based on the German and UK market, there are a lot of strengths in both education systems that can be utilised in the US market as well. Audience: All["Perl", "Community", "Beginner Talk"]

Maximizing Performance and Cost Efficiency in the Cloud

We will explore strategies and best practices for squeezing the most performance out of cloud solutions, while minimizing costs. Despite some focus on Perl performance specifically, the talk will cover many topics, from instance types and architectures, to scaling, storage, monitoring and more.
As many organizations have discovered, including [our own](https://www.spareroom.com), cloud solutions can be quite expensive. Also, cloud solutions may at times not perform as well as the in-house solutions they replaced. However, there are ways to significantly mitigate both the cost and performance issues. We already briefly touched upon the topic of compute performance in my [Real-World Software Performance Optimization](https://youtu.be/V3xuYOgELM4?si=jVBaMRteoUohqQxX) talk in last year's Perl conference. This time while some focus will be on Perl performance, we will go into detail and have a wider discussion around compute instances (types, cpus etc), benchmarking, storage, networking and more.
Furthermore, we will look into tips and strategies to significantly minimize costs - cloud solutions are usually more expensive, but they don't always have to. There are cases where they can provide the best value, as long as you are aware of some caveats.
At SpareRoom, most of our experience is primarily on Google Cloud and secondly on AWS, however a few other cloud providers will also be discussed, especially ones that might offer unique value for specific scenarios or small projects etc.Audience: All["Perl", "cloud"]

YAMLScript - Scripting in YAML

What's the best language for writing scripts?
Is it Bash? Perl? Raku? YAML?
Huh? YAML's not even a scripting language...
Well it is now, and it might be your go to language after this talk!
Ingy wants to show you how to be super productive with nice clean functional YAML code.
Welcome to YAMLScript!While YAMLScript is focused on making YAML configuration be incredible, it's also a complete functional programming language.
It comes with an extensive standard library, tons of external real world external libraries, all the things you expect a real programming language to have.
How is that possible? It's because YAMLScript jit-compiles to another real world language, Clojure.
But while Clojure is a Lisp that runs on the JVM, YAMLScript looks closer to Python and needs no JVM.
It's clean, fast and a great way to script just about anything.
And if your script needs data, well I hope you know we got you covered!

Hold My Place - Automating SQL placeholders by de-interpolating strings

Creating SQL queries with placeholders is a must. But composing strings with interpolation is easier and better to read.

How about combining the best of both worlds?# Hold My Place - Automating SQL placeholders by de-interpolating strings

Many are still composing their SQL queries dangerously by assembling their queries with string interpolation.

Not only are such queries slow and prone to errors, they are also loopholes for injections.

But many legacy projects are full of such examples. And refactoring is often not easy.

And even today many developers choose interpolation, since it's a core feature in Perl and comfortable to use.

This talk shows a current project to convert such interpolations to placeholders, without losing the benefits of ease and expressiveness.

We will cover and explain some in-depth techniques like

- Callbacks in DBI.pm
- Manipulating variables with PadWalker.pm
- Bind variables with tie
- Overloading operators for objects

YAMLScript - Dynamic YAML in Perl and Raku

There's a new YAML loader in town, for both Perl and Raku!
It loads all of your existing YAML files just as expected, but you can also call functions at any point.
You can include other files, fetch web data or query a database! You can merge, concat, interpolate & 100s more.
I think you'll love it!At TPRC 2023 I(ngy) talked about Lingy and YAMLScript.
Immediately afterwards all the pieces fell in place to make YAMLScript the most powerful YAML loader for every language, including Perl and Raku.
While YAMLScript is a complete functional programming language (available right now) its main focus is to fix most of the problems people have with YAML, and also take YAML's capabilities to a whole new level.

In this talk, Ingy dot Net will teach you how to use the YAMLScript loader modules for Perl and Raku.
Then he'll teach you how to easily tame your YAML and do just about anything you'd normally do from a programming language directly in YAML.

I think you'll be pleasantly surprised just how clean and powerful it is when you add YAMLScript to your YAML files.Audience: All["Polyglot", "Perl", "Raku", "Open Source", "DevOps", "Fun", "Data"]

QA concerns in a open source community: how to save the most cows

A discussion of some do's and don'ts while trying to balance community building and code quality in a distributed open source product using the MoSCoW prioritization technique as a framework for QA.When performing QA on code submissions in an open source project, you may be interacting with new members to the community, and people you have never met. While maintaining the guidelines of the community and ensuring code quality are top concerns, a nod must be given to building and uplifting the community, even when failing QA. The MoSCoW method for prioritization, often used in project planning, provides a good framework for giving the necessary feedback, making clear what is required, and giving space for opinion.Audience: All["perl", "QA", "Koha", "Community"]

Raku Next Steps: Hyperactive Metang

Time to start thinking in Raku!
Have you:
* Written nested loops?
* Summed a list, or created a running total?
* Compared elements of one array to another array, or to the same array?
Raku's meta-operators do these (and much more) so concisely that it can change your thinking.
Come let me "wow" youYou are likely doing reduction, production, Cartesian cross-product, combinations, and zipping, even if you don't think in those terms.
In Raku, we have concise ways to express these tasks!

Yay!

...with operators so tight that they can change the way you think about your problem-solving!

Hooray! Large cheer!

...and often with two or three hard-to-distinguish ways to do it!

Woohoo!
Wait, what???

TIMTOWTDI, come find out when to use which way!

Presenting hyper-operators and meta-operators in a way that will move us from typical reactions of "Oh! Cool!" to actual adoption in everyday coding, by focusing on spotting the use-cases. For example, "When you see FOO, think BAR", where FOO might be nested loops walking the full span of the same array twice, and BAR would be the `X` operator.

Direct Access to PDF Internals with PDF::Data

There are many existing PDF modules for Perl, most of which use high-level API calls and hide the PDF internals. PDF::Data takes a different approach, directly representing low-level PDF internals as Perl data structures which can be freely manipulated, and then converted back to PDF format.Explore the capabilities of PDF::Data, a Perl module that offers a unique approach to PDF manipulation by directly exposing PDF internals as modifiable Perl data structures. Unlike traditional PDF tools which shield users from the complexities of PDF internals with high-level APIs, PDF::Data allows for detailed, low-level interactions. This talk will delve into how developers can leverage PDF::Data to gain unprecedented control over PDF content, enabling precise customizations and manipulations that are not possible with standard PDF libraries. We will cover practical examples including dynamic document generation, content extraction, and direct modifications to the PDF structure, providing a toolkit for advanced PDF solutions in Perl.Audience: Advanced["Perl", "Data", "Open Source"]

Native deps a pain? WebAssembly can help!

Want to extend Perl with libraries written in other languages? Interested in adding a secure plugin system to your Perl app? Want to stay away from building and linking native extensions? This talk will cover extending Perl with Extism, a lightweight framework for building with WebAssembly.Traditionally, Perl is extended with libraries written in other languages using the C ABI and linking via an XS extension or FFI. Building and linking a native library or extension into Perl can be error prone and even introduce memory safety issues into a Perl program. Building to WebAssembly (Wasm) enables running code from a multitude of programming languages without building, running, and linking them as native code. How can we easily integrate running Wasm with Perl to allow extending Perl without perils of linking native code?

In this talk, I’ll start by providing basic background information on extending Perl and discussing why you might want to use Wasm instead of linking native extensions. Then, I’ll contrast the development workflow using Wasm both directly and with the [Extism](https://extism.org/) framework. Finally, I’ll showcase how Extism can be used to implement a sandboxed plugin system in your Perl app that supports a multitude of programming languages.Audience: All["Perl", "Open Source", "Native"]

Actually Portable Perl

Actually Portable Perl (APPerl) is a distribution of Perl that runs on several OSs via the same binary. APPerl builds to a single binary with Perl modules packed inside of it. This talk will cover how APPerl works and how it can be used to build cross-platform, single binary, standalone Perl apps.Programming in Perl is awesome, but how can you get non-Perl programmers, even non-technical users to run your program? The easiest way might be to ship a binary. Tools such as [PAR::Packer](https://metacpan.org/pod/PAR::Packer) can be a great way to create a binary, but it requires packing on each target system and is difficult to do right on non-Windows platforms (often due to dependence on system libc). The [Cosmopolitan Libc](https://github.com/jart/cosmopolitan#cosmopolitan) enables creating polygot executables that run on multiple operating systems including Windows, Linux, Mac, and more with the same binary! [APPerl](https://computoid.com/APPerl/) is a distribution of Perl built with the Cosmopolitan Libc that enables creating cross-platform, single binary, standalone Perl apps.

Introduction to Clojure for Perl Programmers

There's a lot about the Clojure programming language for a Perl programmer to like. It's very dynamic and very practical. If you think it's just for the JVM, you're very wrong. Let Ingy teach you the basics of this exciting language including compiling it to binary and using it directly with Perl!Clojure (pronounced like "closure") is a programming language that was created to make Java programming not be a nightmare!
Clojure can use any library written in Java and Java can use any library written in Clojure.
It's core data structures are immutable yet easy to work with.
This makes it a great functional programming language, and makes concurrency simple and reliable.
At the same time it supports mutable data structures when you need them (not very often).
It's a very practical language.
Clojure went beyond Java and the JVM to support other host languages, most notably JavaScript.
These days Clojure can be run directly without any host (no JVM at all).
It can also be compiled to binary executables and shared libraries.
That means you can write "XS" modules in a very high level language.
Clojure has a Lisp syntax, and if you've been wanting to really learn a Lisp, Clojure is a very practical one to start with.

In this talk, Ingy dot Net will teach you as much as he can in 50 minutes about how a Perl programmer can be productive with Clojure.Audience: Intermediate["Polyglot"]

Artificial intelligence, machine learning, and the future of Perl... don't miss it! Future-proof your career with Perl AI.In this talk, we'll review the current status of all major AI projects in Perl.

We will also attempt to answer a number of frequently asked questions, such as:

- Do I have to pay to use ChatGPT in Perl?
- What is a neural network?
- What is an ontology?
- Can AI write Perl source code?
- Can we create strong AI in Perl?

Artificial intelligence is the way of the future, and is Perl's big chance to make a comeback.

Let's make the most of this AI opportunity to join together and put Perl back on top!Audience: All["perl", "ai", "artificialintelligence", "aiperlcommittee", "ml", "machinelearning", "fun", "community", "future", "Perl", "Open Source", "Fun", "Community"]

Fun with Macros

Bending source filters into a reliable mechanism =)# Fun with Macros

Macros are a killer feature of Lisp many have longed for Perl ...

... in fact, it has been possible for a long time to expand and "inline" a function at compile time.

All you need to do is to pair the import mechanism with a source filter so you can insert code cleanly without stepping into the usual trap of source filters.

Coupling that with Keyword::Simple you even have a macro mechanism at hand that works without a "use" statement.

To demonstrate the benefits, we will present various elegant solutions for DSLs, object models, and runtime optimization.

This is an extended and updated version of [my talk at European PerlCon 2019 in Riga](https://perlcon.eu/talk/97)Audience: All["Perl", "macros inlining source-filter inc-hooks", "macros", "inlining", "source-filter", "INC-hooks"]

Learning and Practicing Perl and Raku on exercism.org

exercism.org is an online open-source platform for people to complete syllabuses, exercises, and receive mentoring in a variety of different programming languages. In my talk I will describe the development of the Perl and Raku tracks and how I hope to encourage more people to learn these languages.This talk will go in detail about how Perl and Raku have been integrated on exercism.org. I will describe how exercises have been implemented for our languages, how the in-browser editor runs Perl and Raku tests, the current state of the work-in-progress syllabuses for these languages, and how I try to gently introduce people coming from other programming languages into Perl and Raku.Audience: Beginner["Raku", "Perl", "Open Source", "Fun", "Polyglot", "Community"]

Work It, Make It, Clearer, Faster

Make it work. Make it right. Make it fast.

What does this all mean?

Refactoring a small method to pass all three requirements, explaining each in turn.We've had a bit of code at work that's worked since day one. That's twenty years, and every payment in the system has passed through it. A lot of payments. Something isn't quite right about it though. When a bug report came in a few months ago seemingly related to this twenty year old code, it was time to fix it.

This talk aims to clarify the definition of "right", at least in this speaker's opinion.

Code examples will be shown, including bonus attempts by AI and The Perl Weekly Challenge.Audience: All["Perl"]

Getting Testy with Raku

The "testing culture" in Raku is an important part of both the language and its culture. This talks looks at some basics of writing tests in Raku using the command line tools and language features.This was given a few years ago, since then details of Raku have changed to look a bit more Raku-ish. This would be an updated talk including newer language features & test modules. Audience: All["Perl6 Testing"]

Class: Going Rogue with Object Oriented Perl

This is an in depth workshop guiding people through building a simple text based adventure game using the most recent features of the Perl programming language, as of this writing 5.38 and higher.

We will go through in detail how to build a text based adventure game in Perl. We will discuss procedural generation, RPG mechanics, Entity Container System (ECS) Architecture, as well as the modern Perl ecosystem. By the end of this session attendees should have a functioning if rudimentary video game they built themselves and a better understanding of the mechanics of implementing a non-trivial system in Perl.
