YAPC::Europe 2011 “Modern Perl”

Now that Perl 6 is available in a usable form, over the past twelve months Damian has revisited some of his most popular Perl 5 modules and reimplemented them in "native" Perl 6.

Welcome speech

We'll show a new operator, that combines the best of two worlds

Working with ALSA (Advanced Linux Sound Architecture) tastes like drinking a beer from a plastic glass.

Act needs your love

Ingy dot Net talks about deploying Perl Apps with cloud computing, and showcases ActiveState's current offerings

In this talk I will look at some of the current efforts to market Perl to a wider audience and explain some of the issues we have had/will face. I will be discussing the need to gain a broad audience and how we have to give Perl a Mindshare

Mark Keating will be talking about the recent Google Sumer of Code, Send-A-Newbie and LPW2011 he also has a request for everyone at the conference, something we all have to do apparently..

This talk presents App::ffeedflotr, a program I wrote to visualize data. In the talk, I will show what it can do, and how I use data visualization during development of modules.

Autosplit for CSV files on the command lin

I recently rewrote App::TimeTracker (new version 2.009 recently uploaded to CPAN). App::TimeTracker now allows you to keep track of the time you spent on various jobs and projects using a simple command line interface.

Developing web applications on a local computer has numerous problems: setup time, different platform or software versions, inability for other users to try out new code in development without pushing it somewhere else, and differences from production that are more significant than expected. [...]

Thank you very much for being with us

ElasticSearch is a powerful, flexible, Lucene-based full text search server, with automatic sharding and clustering.

A big poster showing all a database's tables and the links between them is incredibly useful, especially when trying to find your way around an unfamiliar system.

DBIx::Class is a relatively popular database access toolkit, however years after its inception many developers still see it as a mysterious monolithic black box.

DBIx::Class::Tree::Mobius is a new DBIx::Class component to represent and manage trees in a SQL database.

DBIx::DataModel is an Object-Relational Mapper inspired from UML, with special care in expressiveness and efficient collaboration with the underlying database.

This will show you how easy it is to put together a dynamic website using Dancer.

Perl 6 grammars are a powerful way to parse text, and extract structure from it. They take what you already know about regexes and object orientation and bring it together powerfully. It's great, but...what happens when your grammar won't match something you think it should?

What to expect?

1. What is DI?

The aim of this talk is to show how to use the Dependency Injection pattern to write code that is easy to test and build applications whose behaviour can easily change at runtime by defining environments and different sets of configurations.

Web usability is an approach to make web sites easy to use for an end-user. Usability is becoming more and more important on the web. This talk will introduce you on how to do usability testing, even if your target audience is outside your country, which is pretty common in Europe.

MsOffice-Word-HTML-Writer offers an easy way to generate documents fully compatible with MsWord : instead of dealing with the complexity of RTF or XML document formats, just write HTML, add some instructions for headers, footers, sections, etc., and package the whole thing as MIME/multipart. Easy

∙ introduction: why do we need end-to-end encryption?

Earlier this year, your presenter made the choice (mistake?) to finally

Many services on CPAN distributions collect their own information. This is doable, but rather tricky for the current CPAN situation. It's much harder when replaying history, being useful for companies.

A multitude of extension were invented for Perl5, using "source

I will show two techniques I used quite successfully in the last few years to set up fixtures in

The Norwegian Meteorological Institute offers free weather data from a web service. This talk will introduce the service, present some of the data available and the perl module Weather::Metno::LocationForecast that fetches and parses the data

Last winter I took part in GCI - the Google Code-in. I'd like to explain what that involved, what I did and what I learned. This will also be an appeal to module authors to provide tasks for the upcoming GCI.

Don't wander around your first YAPC clueless. Learn a few secrets to get the most of the conference.

At the 2010 QA Hackathon in Vienna, a few people discussed the idea of controling a CPAN install with Git. Since this kind of endeavour requires a good interface between Perl and Git, a first yak needed to be shaved. See the talk about Git::Repository for details.

After looking at all the existing alternatives, I decided to write my own Git wrapper for Perl.

To address an (older) Nokia phone to send text messages through a computer interface, which is easy e.g. for cut-n-paste error messages to colleagues, Linux offers gnokii and a GUI xgnokii.

For sure, you've heard about Go programming language. As Perl programmers tend to be linguists, they should like looking at other languages, even if they never will use them in production.

"The HTML5 hype is out of control. What is it exactly, what ISN'T it, and what parts can you safely use?"

The magnitude 9.0 massive earthquake hit Japan on March 11, 2011. And the plant was exploded. Very soon after the quake, many hackers individually began to hack something around the terrible disaster and for the survivors. At the next weekend, we launched the "Hack For Japan" group to support these developers. Numbers of projects have started through our hackathon events both online and offline.

decentral version control systems are hip, so you have to use it too. But don't worry, Im your best friend and tell you what suits you best and which lip gloss matches perfectly.

It's quite hard to write cross-platform CPAN modules, especially when you use XS to interface with C libraries. Luckily, CPAN Testers tests your modules on many platforms for you. Come see how CPAN Testers helped me to create a fully portable module

For almost a decade, Perl has had threads.pm, a module based on a "fake forking" paradigm. Now, a new experimental module called threads::lite is available, based on concepts from the Actor Model and pattern matching

In the quest for everything in Pure-Perl how low can it go

The stereotypical business architecture is fundamentally flawed.

A short rant on the state of the community outside of yapc-business-hours

In the lightning talk we would like to present the main idea of our application architecture to inspire intermediate Catalyst users and get feedback. This is what our application is about:

Get a PAUSE account and upload your first module to CPAN

An introduction that will include topics like:

Other talks on the beginners track explain how to create Perl modules and how to test your code. But how do you know whether your tests are doing a good job? One technique is to use code coverage.

Perl has amazing support for data structures. Hashes, Arrays, Queues, Stacks, are all first class citizens in Perl. This class will give an introduction to the basic data structures and the ways to manipulate them. It will include topics like:

An introduction to writing readable Perl code, for people who write Perl that other people may want to read. Covers the most important lessons from Perl Best Practices, and ends by showing how to use Perl::Critic to test that you are meeting the standards set out

This lightning talk will be a half serious rant about not being overly concerned with how fast various Perl constructs are.

The Data::Iterator::Hierarchical module allows nested loops to iterate in the natural way over a sorted rowset such as that which would typically be returned from an SQL database query that is the result of naturally left joining several tables.

Successful businesses have often built a code base over a number of years. The tempation is to start from scratch, but the reality is you usually can’t. So how do you get to Modern Perl

Interchange is a Open Source eCommerce software written before the advent of any modern Perl. Thus we implemented a lot of things like running a server, dispatching, parameter parsing, session handling and templating.

Parts of the API are not the highlights of WxPerl. But during this talk I show you, how to write clean and concise GUI-Apps. Helper modules and advanced Wx stuff not everybody knows are topics that will be also touched

We will look at how the routes based dispatcher works, the built in rendering system as well as cutting edge features like HTTP Web Socket support and the CSS3 XML parser. This talk also covers the Mojo HTTP User Agent

We all know that CPAN is one of Perl's biggest advantages. But sometimes, you find yourself using a CPAN class that doesn't have quite enough features for what you're trying to do. What's the best way to deal with that sort of situation?

It's often useful to check that your DBIx::Class classes provide the methods you expect, and no-one has sneakily stolen or broken methods when you weren't looking.

This talk will introduce some usages of the modern Perl in the leading enterprise scene in Japan.

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.

One of the significant new features of Perl 6 is its support for lazy and infinite lists, arrays, sequences, and other data structures. However, these new features have far-reaching impacts on the whole of Perl 6 design and implementation. [...]

Perl 6 hackathon is a one day event for those who want to look at internals of Perl 6 and its development process. There will be people who are responsible for Perl 6 design, specification and implementation, and Rakudo developers.

A short promotion for contributors for a forthcoming book about conference organising

MIDI allows to exchange Note/Controller messages between electronic musical instruments and/or software. Being almost 30 years old, MIDI is still widely used in music production (and not only). Perl running on a Linux machine equippped with a MIDI interface can use MIDI::ALSA module to intercept incoming MIDI messages, process them in realtime and send to appropriate devices. [...]

Oslo has had a Perl Mongers group since 2002. Here are a couple of highlights of what they've done

I've been running Perl training courses for ten years. Some have run alongside conferences, some have been internal courses for companies and some have been public courses.

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!

Currently shared availability of routines is achieved through manual plugging of these in the symbol table; this is a Request For Comments on the speaker's current practice of handling this

About a year ago, the Rakudo Perl 6 development team released Rakudo Star. Implementing a wide range of Perl 6 features, it marked a point where more people could jump in and start exploring the Perl 6 language. They did, and over the last year the community and module ecosystem has grown.

Redis is one of the recent crop of databases that avoid SQL, sometimes called NoSQL. This talk will introduce Redis, what it's good for -- and probably more importantly what it's not good for. The various modules for using Redis from Perl will be covered

Module::Build is dying, what are we going to do about that

While relational databases represent a valuable and

The Roman number system is much more complicated than most people think. My talk will present the historical features this system had and how various CPAN modules deal with them.

Using mod_perl had some benefits over plain CGI.pm. You got some sort of persistence and a tight integration with Apache. Unfortunately you got a tight integration with Apache. This makes mod_perl have some obscure quirks and can make mod_perl applications hard to test and debug.

As Perl developers we often need to work on remote servers, deploying, debugging, and sometimes even writing code. SSH makes this possible, but by default it can be rather cumbersome to work in this way.

At work (XING.com) I wrote an HTML sanitizer for our WYSIWIG editor. It is based on whitelisting.

This talk looks at the larger CPAN Testers ecosystem, and aims to show how both users and authors can reap benefits.

For connecting to Jira by Soap protocol i use python module suds,

I'm lazy and forms are hard to do right. If I can be lazier and do them better, that would be a win. So I wrote Spark.

YAPP - Yet Another Perl Podcast.

Perl 5.14 makes some previously-esoteric optree magic much more accessible. This talk will look at the semantic and performance effects that can be achieved by judicious optree editing, taking advantage of the new facilities. Some XS knowledge is required.

Perl 5.14, building on the experimental parser hook mechanism of 5.12, introduces revolutionary new facilities for extension modules to add new syntax to Perl. This talk, by the author of the new facilities, will look at how to use them effectively. It's a lot easier than last year's shenanigans with 5.12, but still requires writing XS.

Setting up a Catalyst/DBIC app for scability and redundancy

My plan for 5.16 are types. Type-checks make perl slower and might come handy for discipline,

Dates, times, time intervals, clocks, calendars, and related phenomena are major contributors to hassle in programming, and the source of innumerable bugs. This talk will explain why it's such a complicated area, and how best to think about it to avoid getting confused. Leap seconds will be demystified, and then remystified as the truth turns out to be stranger than you imagined. [...]
