YAPC::NA 2014 • Orlando, FL

Perl's history starts with Unix. In this talk Marty will explain some fundamental Unix concepts in Perl

Some talks carefully guide the listeners through the entirety of a topic, starting with the basics and ending with the fine details.

Dates and times are confusing and crazy. What nut invented Daylight Saving Time? Someone who'd never imagined a computer, that's who!

The past year has seen multiple advances in stemming algorithms and tools on CPAN, including new stemmers that previously didn’t exist in Perl for multiple natural languages. Let’s take a whirlwind tour of new stemming development in 2013–2014 and demonstrate how Shutterstock uses them for multilingual information retrieval

When managing versioned migrations for a PostgreSQL database with hundreds of tables became too slow and unwieldy for our team to coordinate, we came up with our own tools to do it. Switching to apgdiff drastically dropped the time to create database migrations. [...]

This talk is about lessons learned while designing, building, and operating asynchronous servers. Instead of focusing on the concepts of async programming and the benefits it provides in terms of performance and determinism, we'll discuss the problems that inevitably come up.

What's this? Databases without SQL? Data models without normalization? Come to this brief introduction to see how you can get up and running with MongoDB in just a few minutes. We'll put together a simple Mojolicious::Lite application that takes advantage of MongoDB's document-oriented data model and gives you just enough information to dive right in and get your hands dirty

You know how email hates the living? iCal hates the living more. recurrence rules are likely turing complete. and the original form of ical is different enough that converting from it to the current model is anything but trivial -- i could find nothing for this task, so i wrote it, which included patches for Data::ICal

Coffee, Java, Black gold. Whatever you may call it, coffee is a lifeblood for many of us. But yet, many of you settle for low quality, poor tasting, (and probably stale) coffee. Why? This talk will be a beginner's guide to home roasting. It's an easy, fun, and affordable way to get some of the freshest coffee possible. [...]

Description:

Currently, most new development on the 'net is done on top of a CMS. Out of the box, you get user accounts, password recovery, a message system, discussion boards, moderation, and more. Plugins give you 90% of whatever common type of site you're trying to create, such as a job board or web shop.

In this talk I'll discuss how DBIx::Class, the most popular ORM in Perl, can be used to the fullest. In the past I've done whirlwind overviews of DBIC features, shown a bunch of DBIC extensions, and even had whole talks based on cpan modules that have DBIC at their core. This year, I will take it a bit slower. [...]

Making your own beer and wine is actually quite easy. We're pretty new at it ourselves but have managed to successfully brew drinkable beverages. We're brewing 1-2 gallon batches of beer in our tiny NYC kitchen and also making fruit and honey wines. You don't need a lot of space or fancy equipment. [...]

Several stories of how DTrace saved someone's day when *nothing else* could.

When attempting to learn Dancer I ran into the problem that all the documentation started from "Here is a 'Hello World' script". But that was assuming many things were set up and configured and that just was not true, at least not on my server.

Docker is a lightweight virtualization container technology for Linux. With less overhead than a full virtual machine, and more isolation than a debian or rpm package, Docker is becoming an important emerging tool for developers and devops to handle testing and application deployment. [...]

Perl is a language almost perfectly designed for implementing Web data services. But even with this marvelous language and the plethora of useful CPAN modules that we have available, designing and implementing a useful, efficient and well-documented data service is no easy task.

DBIx::Introspector will help users detect what database they are connected/connecting to. It should help people create alternate ORMs that actually work with many databases, instead of just Pg, mysql, and SQLite. [...]

An improved Carp::Always, giving you stack traces for all exceptions and warnings, including exception objects

?- predictable(reality).

Pittsburgh Perl Workshop will have a crowdtilt and may happen in late October.

Some years ago I developed a standard regex module for company-specific items like lot numbers, equipment identifiers, etc. Retrofitting our existing library of production control scripts to use this module was a ton of work, but in the end was a huge victory. Life is so much better now.

Have you ever had a segfault silent and mysterious in a production system? There is a way to find out more, and I'll show you

Ever wanted to contribute a module to CPAN but found it difficult to navigate the in's and out's of the labyrinth? I'm a first time contributor that also found it hard to know what to do and what not to do. I still don't know everything but if you come to this talk you should leave knowing at least a little bit more about how to get your code added to CPAN

Foreign Function Interface (FFI) is a popular method of implementing extensions that rely on C libraries in languages such as Ruby, Python and Java. FFI has not hit the big time in Perl, but it has some advantages over Perl’s historical extension language XS. Migrating parts of CPAN from XS to FFI may ease the transition to alternative Perl implementations or Perl 6. [...]

Perl testing is kind of like swimming in the ocean: it's fun to start with but gets deep pretty quickly. Even if Test::Simple does most of the work, you'll eventually have a reason to dive into deeper waters. So, think of this talk as a glass bottomed boat: it gives you a chance to see things without getting bit or drowning...

Talk brief: Perl is more than just a hodgepodge of modules and sysadmin scripts. Learn just how easy it is to write a graphical user interface for your programs, and attract more than commandline junkies to your programs

We hire lots of really smart people that really know software development, architecture, and scaling critical systems. There is one thing that many of them don't know and that is Perl.

Every Perl programmer has opinions that probably differ from the rest of the community. Don't be afraid to express that

While Rakudo Perl 6 is coming closer and closer to being production ready, good old Perl 5 has taken a lot of ideas of Perl 6, for better or for worse. I will look into how some things have worked, and some haven’t. And why. And how in the end, everybody is getting more and more used to Perl 6 (like) syntax

So you want to learn what it takes to run a Perl workshop or a conference in your home town.

What settings are best for running Linux inside a virtual machine?

How we think about a problem determines how we think about that problem's possible solutions. If we get the problem analysis right, the work that follows seems to flow along a natural course. Why is that? Where does that sense of a "natural course" or an "obvious solution" come from? Can we do it on purpose?

There are a number of good web frameworks available for Perl. This talk will compare them by showing the same website written in different frameworks (Catalyst, Dancer 1 and 2, CGI::Application, CGI::Ex::App, and others), and what the advantages and disadvantages of each framework are, so that you can choose which one you want to use

Two rules for learning a second language that have guided me to become fluent in Japanese.

This past year, my team adopted Scrum. I also happened to read several books about performance and inner drive.

This talk will touch on a few high-level things to consider when working towards Internationalization and Localization of products/websites

Rust is a new programming language being developed by Mozilla for low level and systems programming tasks. Its goal is to be a replacement for C or C++ in a lot of the environments that they are currently used in (including embedded systems), while providing much stronger memory safety and concurrency guarantees, as well as other modern programming language features.

Keeping our old Apache 1.3 with mod_perl application running, even when browsers conspire to choke it with requests

It's now 2014 and three years since I gave my "Pimp Your Mac With Perl" talk at YAPC::NA in Madison[1]. In this follow up talk, consisting of entirely new material, I'll be talking about new technologies that have come along since then (having seen the prior talk is not required.)

Civilian use of autonomous vehicles, airplanes, and helicopters has become increasingly popular in the last few years for everything from aerial photography to beer keg delivery. Learn about how Perl is entering this new field with UAV::Pilot

Remember the saying from Perl-people? "We suck at marketing". Well, not all of us. Some of us are rather good at marketing. Some well-known Perl heroes are good at what they do and good at promoting that, and promoting Perl at the same time. I do my bit and it seems to be appreciated every now and then. [...]

A discussion of the Math::Prime::Util module, including some of its uses for basic number theory, as a Math::Pari replacement and enhancement, and some uses in Perl crypto modules

irc.perl.org has had some changes recently, including the introduction of "community operators". This lightning talk will introduce them and talk a little bit about how the new governance system will work

Are you using MetaCPAN? Do you want to hook up to its cool API? Wrong number?!

Core changes I'd like to work on, for those intereste

Announcement for Netherlands Perl Workshop 2015 in Utrecht. Compared to 2013, this year's NLPW had an increase of almost 100% in attendees. We want to try such an inrease again

Phil Wells is a QA engineer at Kaplan Test Prep, and in this talk he will demonstrate how he uses Perl's Selenium bindings and good old-fashioned OOP to verify the complex configuration of KTP's student portal. Attendees will leave with a good idea of what they can do to build a maintainable, resilient functional test framework

This talk looks at web users from a two different perspectives. First, we look at identifying techniques to determine web user identities from a server perspective. Second, we will look at obfuscating techniques from a user whom seeks to be anonymous. Perl techniques will be highlighted

I shall discuss the trials and tribulations of raising geek children

An introduction to Marpa, a parsing library for Perl, and some of the cool ways that it can simplify relatively complicated parsing tasks. Includes a little bit of history and covers improvements made since a previous version of this talk in January 2013.

In this talk I'll be:

After 20 years of popularity, Perl has established a reputation for reliability and backward compatibility, but it’s also still a changing, evolving language. This year’s release of Perl 5.20.0 brings some significant and exciting new features, as well as a number of little improvements to keep making easy things easier and harder things possibler.

“Perl on NetBeans” is intended for Perl programmers who want the intuitiveness of a great editor with the ease of being able to execute the program without having to do it through a command Interpreter. Also, it has the capability to inspect the austerity of your Perl programs, and format the same in accordance to the best practices and conventions. And it does much more :)

So you've built a fancy web application with a fancy database back end, but now that people are using it you've got a few features timing out... and making for angry end users. In a normal procedural program, each task is done when the other finishes. Another option is to hand off the hard work to something else and give your user a status rather than a timeout! [...]

In just 5 minutes David Farrell (PerlTricks.com) will convince you that writing about Perl is like a dungeon hack, and show you how the dungeon hack metaphor can help you write better articles

An introduction to the hardware hackathon and how the Perl (culture and code) fits into the Internet of Things and beyond

Perl and Scientific Programming: A panel discussion

An update on my lightning talk from YAPCNA 201

Once again the blakey folk that lurk around comment posts, dubious statistical sites and social media beartraps that litter the internet have called forth the demise of Perl. It was so sudden, yet drawn out. Apparent when you close one eye and look at the figures upside down hanging from a train in a Budapest station.

PkgConfig is a pure Perl (5.6.2+) implementation of pkg-config that comes with a Perl API that has some advantages over ExtUtils::PkgConfig

Politics is ugly. I'll talk about how I'm trying to help.

You want a (Perl-) job at company X and you know that company X has a list of wanted capabilities with their developers? Prepare well, start early and make yourself findable.

This talk drops virtually all abstraction and shows how to program the simple 8 bit processor and custom designed video hardware in the Atari 2600 "VCS". Users familiar with high level languages might find this an interesting introduction to how CPUs actually work.

Overview and live demonstration of the RapidApp web framework (www.rapidapp.info) which provides turn-key web interfaces (Web 2.0/AJAX using ExtJS) that tie automatically into various backend data models.

PerlIO is a part of perl every perl programmer uses, from newbie to Larry himself. Yet still it's something that's rarely given proper attention.

If serial killers would use these coding patterns as reasons for their killing sprees we would set them free of charge. Innocent men and women who could not be expected to remain silent in the face of such bothersome behavior.

In order to enjoy this talk you do not need to know Perl, nor SQL, nor do you need to be an accountant.

NumPy and SciPy are a collection of packages for scientific computing in Python. Together they extend Python into a powerful open source data processing and prototyping environment many scientific programmers are choosing to use instead of expensive, proprietary commercial systems such as MATLAB.

My grandfather served in the US Navy during World War II. His ship was sunk by the Japanese. He then spent 3.5 years as a Prisoner of War on the Burma-Thai Death Railway ("The Bridge on The River Kwai").

The traditional approach to writing a daemon involves forking twice, closing input/output handles, chdir(), writing a pid file, becoming session leader, using syslog, and a lot of other nonsense.

Placeholder for SotV, will update usefully late

Best Practical took over primary support of rt.perl.org and completed a major upgrade last year. We've also worked with the perl.org admins to upgrade and support rt.cpan.org. We'll talk a little about the history of the systems (why does rt.cpan.org exist?) and how they work today. If you taunt me, we'll talk about how the email integrations work. [...]

Stepford is like Make, Cake, Rake, Sake, Jake, Blake, Fake, and Wake. Okay, I made most of those up.

Map, Grep, and Sort are powerful Perl built-in functions that can simplify your code and improve performance.

Sub signatures have made it into 5.20 as an experimental feature. While it's still too early to say where signatures are going, there are some very exciting directions we can go, in core or as extensions. [...]

Welcome to YAPC, brought to you by The Perl Foundation. We'll take a few minutes to get you caught up to speed on what is happening in TPF

Abstract

Is there a CPAN module you have written or rely on that you want to make sure works with the next version of Perl 5? Test it against Perl 5 blead. This talk points you in that direction.

Small memories flooding our consciousness like a river of delightful experiences, carrying us through our lives, tugging at our heart, pointing us towards endless appreciation of what many fall prey to forgetting: our love of solving puzzles and our joy of transforming reality and life itself.

Have you ever wanted to learn the secrets of the dark masters of Perl? Ever been curious about what an *SV is? Maybe you just want to make a subroutine really, really fast, but you're terrified of this thing called XS that stands in your way. This talk presents the Perl API for beginners from the ground up, explaining everything you need to know to get started hacking Perl in C. [...]

Threads in Perl adds a new dimension to program development through the asynchronous nature and multiple stories that are unfolding simultaneously. Parallelism can multiply the speeds of certain applications as well as take advantage of the increasing number of cores in modern CPUs. [...]

Unicode is much more than just characters. The Unicode Consortium defines open standards for collating, parsing, and formatting data in much of the world’s languages. The Common Locale Data Repository (CLDR) is the largest standard repository of locale data along with specifications for its use and is a powerful resource for software localization. [...]

I'm interested in the Open Source phenomena. That is the phenomena that makes intelligent people work for free. It's not surprising that both the business and academic worlds also want to know how this works. Businesses have been taught that in order to get and retain the best people they need to pay a good salary and provide a variety of benefits. [...]

This talk covers a pattern that I think is powerful, flexible and fun to implement using roles from Moo(se) to develop web service clients. Along with outlining the overall pattern, this talk will present tips and tricks to write good consumable clients that are easy to get other people using

Excessive accessibility or just extra ecstatic explosions of extremely extraordinarily expressive flexible intoxicant? Excellent exclamation! Multiplexed oxygen-fuelled perplexed pixies relax in saxophone-shaped taxis because they pay no taxes. Inexcusable!

Some shaving of noble note

I am doing something, and want your inpu

Based on recent work on the B::C module, it's now possible to build a working binary which can do away with the majority of startup expense a typical perl program would have.

Last year's hilarious talk - update with this year's mistakes, too! Beginning students make beginner mistakes, just like the rest of us. Sometimes comical, sometimes painful, bad code can teach us as much as good code - sometimes more. From eq vs == to fork() while fork(), learn what not to do - preferably before you do it.
