Say you're writing a system that uses the observer design pattern. What happens if instead of passing around the NAME of an event, you pass around an OBJECT representing the event? Turns out, a whole lot of goodness!

Announcing Carton, awesome Perl CPAN dependencies tracker and deployment tool

Music making is hard, so musicians are cool. Programming is hard, so programmers are weirdos. Huh? How'd that happen? How do we change it? I have a few ideas I'd like you to hear.

I believe that the perl community and even people outside the community can help make perl events even better than they are today.

This presentation points out the problems which organizations get in to when they lionize getting something into production "quick and dirty" and when they disparage practices needed for the long-term maintainability of programs

This talk will be about Termcast, a broadcasting client that allows you to stream your terminal sessions across the internet and some excellent Perl modules that are being developed to accomplish this. The talk will also cover my intentions for writing these applications, and will finish with a short demonstration

Data::Manager combines Message::Stack and Data::Verifier. This combination comes together synergistically so you can build web applications that don't suck. We don't use form generators, reflectors or any of that. Just raw, uncut but high quality markup and code.

A lightning talk about my new distro for email, Courriel

In 2010 I spent a good amount of time hacking on and using DBIx::Class::Journal. It is great for getting solid journaling. What it's not great at is using that data. [...]

Plack and PSGI have opened the new landscape of Perl web frameworks and servers. When it comes to the deployment of your web application, it gives you so many choices that would even make your sysadmin mad. This talk will quickly walk through the PSGI supported web server environments and case studies of website deployment with middleware configurations

At Shutterstock.com, photographers ask us for input on what topics they should photograph to make more money. We've been writing various tools to help expose 'content gaps' in our data, that is, subjects to shoot that we believe will sell well to underserved markets. We've built text and graphical web-based interfaces to surface these content gaps to contributors. [...]

How a Perl organization (Japan Perl Association) was born, and how it operates.

I recently acquired the Baltimore Perl Mongers Leadership role through no fault but my own. I'm trying to work with companies, and other tech groups in my area to build my group and promote cross pollination.. I've never given this talk before, but I thought some of the things I've learned may help other PM's refresh and draw in a broader audience

The Information Security atmosphere has moved beyond 1337 h4x0rs and 5cr!pt |<iddi3s. Attacks and attackers are more sophisticated (and more stupid) than you could imagine. As an InfoSec professional, I'm frustrated that my peers have failed to recognize the potential in their SysAdmins, Network Admins, and Programmers.

This talk walks through a couple of tutorial applications written in Dancer and provides an overview of the most important aspects of Dancer for someone who isn't at all familiar with the framework, but understands Perl in general and web application programming.

ZeroMQ is a brokerless messaging system -- like sockets, but better! This talk will be about what you can do with ZeroMQ, and how to use it in your Perl application.

The jackalope is a mythical animal of North American folklore (a so-called "fearsome critter") described as a jackrabbit with antelope horns or deer antlers and sometimes a pheasant's tail (and often hind legs). The word jackalope is a portmanteau of "jackrabbit" and "antalope", an archaic spelling of antelope.

We are not saying yet, but something interesting will fill this space

Accessing a database at process startup for static information is common, but can be hard on the database in a production environment. Another bad alternative is re-checking the data status every time it is used. An AUTOLOAD can handle the issue by lazily installing the sub, but makes it impossible to use can.

Tech­niques and a call to ac­tion on how to mar­ket Perl

*We* know Perl is powerful, pragmatic, and pleasant--whether we're munging data, running websites, automating processes, or building the next big thing. We happily install (and occasionally upload) the latest and greatest of CPAN. We know whose books and articles and blogs to read. We lurk on the right mailing lists and idle on the popular IRC channels and even share meals at YAPCs.

Getopt modules, such as Getopt::Long, are used for processing command line options. There are over sixty Getopt modules on CPAN, which can be intimidating to select from. This talk will highlight some of the Getopt pearls that have been released in the past few years. Both beginners to command line processing and seasoned command line mungers who want to catch up with modern Getopt are welcome

Toto is a simple way to formalize the navigational structure of a web application, in the spirit of BREAD and CRUD, but flexible and extendable for real-world situations.

I'll discuss the math roles and classes in Perl 6, including Numeric, Real, Int, Rat, Num, and Complex -- how to use the existing ones and a quick introduction to creating your own. (I've been one of the main Rakudo implementors in this area.

The Open Web Application Security Project publishes a Top 10 list of web application security no-nos. This is a quick overview of that with demonstrations in Perl(ish) code

I'd like to talk about another perl success story - perl and bioinformatics.

Every new release of Perl comes with a big list of changes, plenty of which seem carefully worded to make the average Perl programmer wonder, "Wait, do I care about this? What the heck is the global interpreter phase?" Perl 5.14 is chocked full of great improvements will actually be useful in day to day programming, and this talk focuses on those, leaving the weird esoterica for another day

The past few years have seen a renaissance of Perl development. With an annual release schedule and an ever-growing list of core contributors, the Perl community is more vibrant than ever before.

As part of a Senior Design Project at NC State University, a team of Computer Science seniors use()d Perl to create an internal network-diagramming tool for AT&T Business Services. Perl provided text parsing, database access, an interface to the Graphviz graph visualization tool, and a web-services interface to the tool's front end. [...]

As with many programming languages, it’s very easy to find Perl code that can best be described as “write only”. Cute tricks, short variable names, inconsistent spacing, dubious reliance on default arguments… Even without the added challenge of a whole extra embedded language (regular expressions), some Perl programs deserve to be referred to as line-noise.

After years of writ­ing PHP day in and day out, I de­cided to take a job writ­ing Perl for the first time. I dove head­first into Perl think­ing the trans­i­tion would be just a matt­er of a learn­ing a few dif­ferent func­tion names. Perl's sub­tle nuan­ces com­bined with years of hab­bits left me frustrated and con­fused. [...]

Do you ♥ your Modules? Want to take them to the future? Imagine a world where every Makefile.PL is one short line, your documentation writes itself, all your tests are just data (they run in Perl 6 as well), and getting a change to CPAN is just a 'make release' and a beer away. Confused? Come find clarity!

Update: I have started a github repo with the code examples from the talk here: https://github.com/Hercynium/anyevent-examples. I hope to add more over time and would love to get more from anybody who wants to add anything!

Thanks to Damian Conway, the joy of inheritable grammars has been brought to Perl 5.

Sure, I know this is a Perl conference, but I thought it'd be fun to share something a little similar but a little different. Vala is a programming language from the people behind GNOME, and it's designed to wrap GObject - how GNOME does OO in C - in a language resembling C# or Java. [...]

Most asynchronous Perl programming is unnecessarily dynamic. It conflicts with object orientation, and it reintroduces memory management issues that some of us learned Perl to escape.

Stackato is a new platform for dynamic languages based on Cloud Foundary from VMware. This talk provides a brief overview of the Stackato architecture and shows how deploy Perl applications on it

Here I'll show a little technique which I've used again and again over the years. It's not rocket science, but it has been helpful in getting a query logged so that it is dead simple to copy and paste

At work we developed a secure WYSIWYG editor. I built the backend HTML5 sanitizer based on whitelisting. It supports multiple profiles (feature sets) and uses XML::LibXML. The frontend part shares the same feature sets with the backend.

Programming in a business environment puts some unique requirements

The Perl community needs to make an effort to codify tribal knowledge. Newcomers should be able to get the power the insiders use without being an insider. I will challenge core perl hackers to keep this in mind when considering new features presented on p5p, and I'll challenge newcomers to the community to demand better from the stewards of the language

... you'll find out

I'll talk a lit­tle about what The Game Craft­er is, but more im­por­tant­ly how Perl has been a big part of mak­ing it the suc­cess it has be­come. I'll di­vide my time equal­ly bet­ween three th­ings: 1) What is it? 2) The Perl code be­hind it. 3) Measur­ing Suc­ces

Most threading libraries provide basic primitives along the lines of POSIX threading, such as thread creation, joining, locks and semaphores, and expect the programmer to manage their efficient operation and utilization. The GPL'd Threading Building Blocks library from Intel is an attempt to bring sanity to this. It instead provides algorithms for a collection of common uses of parallelism. [...]

Some announcements while the Lightning Talk speakers finish setting up

This lightning talk will mention some ways that Grant Street Group uses Perl to wring out adequate performance for things like: an auction with billions of bids; an e-commerce site with about 1M accounts; and data conversion of customer databases as large as 50GB

Do you hate 'No documentation found for "YAPC"' errors? Does the idea of reading about PERL code in a web browser offend your delicate sensibilities? Do you long for a world where scripts are object-oriented? Do you enjoy fun things?

Type-checks make perl slower and might come handy for discipline, but using types will also offer many optimization possibilities.
