Proceedings

In this talk I’ll be sharing some of my personal experience developing CPAN modules as a part of the Japanese Perl community and also talking about some Perl web development trends in Japan.

As OLTP systems operate it often turns out that there is a need for some reporting features that were not initially planned or that the existing ones cannot work efficiently due to OLTP design implications. Enterprises sometime require the availability of large amount of data to report on but on other occasions it is sufficient to provide efficient reporting option against a few-quarters-old data. [...]

This talk aims to give an overview of recent changes in CGI.pm and some lessons learned from maintaining the module; including, but not limited to: github, pull-requests, legacy cruft, test coverage, RT, vendor module management, silence and noise.

Don't speculate! Benchmark!

Amusewiki is a new library-oriented wiki engine which focuses on long-term archiving and high-quality output formats. It's written in Perl using Catalyst, Template Toolkit, DBIx::Class and a bunch of home-brewed modules. The texts are stored under revision control using Git.

For two years in a row I've been working on the MoarVM JIT compiler. When I started the whole concept was mysterious to me. But JIT compilation is a rich an interesting topic at the intersection of two very different approaches to computation. [...]

cperl - a perl5 with classes, types, compilable, company friendly

This talk will go step by step through the process of auditing a CPAN module for security vulnerabilities. We'll focus on translating basic principles into concrete findings and develop proof of concept exploits to go along with the findings

My goal with this talk is that you'll see how easy it is to implement e-learning materials for programming courses - and why you should.

Presentation of the upcoming Barcelona perl workshop

A finely honed hatred of every systems tool I have to work with led me to

Perl 5 and Perl 6 are sister languages in the Perl family. Being sisters, you'd expect them to talk to each other all day long about pretty much everything. Sadly, quite the opposite is the case.

> Wow, i watched until the end waiting for him to say that that was all a joke and

Can we port a heavily used perl5 module to perl6 keeping all the goodies it has?

In this talk, I will introduce a new piece of software called Carmel, which allows you to manage CPAN dependencies in your application.

Workshops and conferences of next 9 month

At the London Perl Workshop last year I got carried away and announced that I would write a book about modern Perl web programming. I promised that it would be ready by the next London Perl Workshop.

Convos is a chat application that runs in your browser. It allows you to be persistently connected to IRC servers, where you can leave the office and open up the conversation on the bus without being disconnected.

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.

A light-heated meander through IT history explaining how and why ASCII can play nasty tricks and what can be done to detect and fix them.

How to connect the agile principle "Working software over comprehensive documentation" with eXtreme Programming values of Honest communication and Rapid feedback and practices as TDD, Continuous integration, Whole team and Small releases.

In a distributed architecture, it's often required to spread information about a master data update to several client apps. You can do this via REST, but if a client app is temporarily down or too busy to accept requests, it's going to miss the information. Adding a new client app requires changes to the master app. Asynchronous messaging helps to avoid such a tight coupling of components. [...]

In which a humanities major reads a bunch of papers on distributed systems theory and attempts to explain them in plain language.

Containers are a new technology that has been gaining importance in the mainstream industry in the past two years.

Use of some new Perl features can be turned on by the "feature" pragma - e.g. say, switch, state, signatures. Some other additions are turned on automatically in respective versions of Perl and are usually just mentioned in perldelta. I'll introduce Syntax::Construct, a module to explicitly declare which of the latter features a script's going to use. [...]

The German Perl workshop http://act.yapc.eu/gpw2016/ is from 2016-03-09 until 2016-03-12 in Nuremberg. This is the 3rd workshop in the 10 years short history of the Erlangen Perl mongers.

...In this talk, Larry will explain that his relationship with Perl 5 and Perl 6 is much like that of J. R. R. Tolkien's relationship to The Hobbit and The Lord of the Rings

In this talk, I'd like to introduce the audience to modules and tools that are heavily used in Japan, but not so much elsewhere.

This talk goes over some problems with exception-based error handling and presents an alternative in the form of restartable exceptions (sort of) in the form of Worlogog::Incident and Worlogog::Restart. These modules bring ideas to Perl that were straight up stolen from Common Lisp's "condition" system

The Perl community and culture shaped fundamentally the developer I am today.

This talk will explain some things about how one can start contributing to perl5 core.

Let's make your local server based web application!

The talk is about the state and the features of this internationalisation distribution. Starting with the history of this, I will present an overview and the goals. Later I describe some problems and the solutions with this distribution

When people ask me how I know Perl 6 is going to rock, I explain it's because I already have a bunch of Perl 6 code in production.

Measure::Everything is a rather new module on CPAN that aims to make it simple to record various stats. It is heavily inspired by (you might also call it "mostly stolen from") Log::Any.

PERL is that horrible language that script kiddies used to write formmail scripts and guestbooks back in the 1990s.

Web scraping is fun. It makes data accessible, works around API limits, and makes us feel like gods.

I got inspired by David's talk...

Monitoring is essential to ensure the integrity of your production systems. Lots of things can go wrong which you wouldn't notice otherwise. Disks fill up to the brim, ordering in your online shop doesn't work anymore or data exchange with other systems ceases to function. All of these result in money lost, upset employers and customers going to the competition.

I have been dive into the domain of "search" for the past few years, there are many interesting finding and experiences during this time.

Net::SSH::Any is a little know module with lots of powerful features that anybody using SSH from Perl should know.

A short talk to demonstrate OAuth2 support with Mojolicious, showing available modules/plugins to make this a bit easier. Broken up in to four parts:

In William Hill we decided to build the “new stack” for customer data-driven business, it has been an aggressive adoption of complimentary distributed frameworks that play very nicely with the key Reactive tenets of Spark together with Scala, Akka and Cassandra, and make the company’s data platform Reactive all the way through. Each technology assumes a different role that compliments the others. [...]

OpenStreetMap creates and distributes free geographic data for the world. Despite its name, OSM offers much more than a map of streets.

No reason. We just need code that makes processing faster!

Architecturing CSS is hard. We (usually) don't treat CSS as part of the codebase and this leads to a lack of tools and patterns to build big site's styles.

See here http://act.yapc.eu/ye2015/panelpage.htm

What's the difference between parallel and concurrent? How does asynchrony relate to them? What sorts of solutions fit what sorts of problems? And how do these solutions look in Perl 6? Come along to this session to find out!

A brief look at The Cult of Done Manifesto (http://www.brepettis.com/blog/2009/3/3/the-cult-of-done-manifesto.html) and what it means to me

The act of computer programming often involves the use of creativity to do things such as; solve problems, design APIs and architect solutions. Can we then infer that the use of creativity during the act means that the produced result is a piece of art? Of course not, but does that mean that code itself cannot be viewed in an aesthetic light? Can code be art? For that matter, what is art?

My first YAPC was in 2013, Kiev and was sponsored by the community - through the Send-a-Newbie program.

In this talk I'll explore different technics for web crawling and scraping on the wild using several perl and some other tools, but mostly using Mojo::UserAgent and Mojo::Dom.

In the history of various arts, there have been turning points in expression which have, in turn, led to perceptual changes. The shift from Victorian to modern poetry at the beginning of the 20th century led to more open and free verse and a shift from controlling nature to embracing it. [...]

How to use Perl 6 as a simple alarm clock when other technologies fail

In this talk I will cover the use of Perl for some humanistic (and occasionally, arguably, artistic) pursuits: that is, investigating medieval history and the texts that carry that history. Alongside the sorts of war stories that cropped up in the medieval Near East, I'll share my experiences writing software in a land where development almost always stops with the demo

I had a problem: got two somewhat-structured music playlists that were overlapping and I wanted to merge them together.

An introduction to Bailador, the light-weight web framework of Perl 6

Polish National Library owns 2.8m books published after 1901. Electronic catalog covers roughly 50% of that. On eBay/Allegro/Swistak there are just now 4m+ books. Can we use that to fill the gap

There are a lot of good Open Source apps to create webshops, and there is good ERP/CRM integration already done on many commercial products. Why do we need yet another webshop?

Since November 2014 I've been spending a lot of my time on recruitment and my main target is Perl developers.

Experts, senior developers, thought leaders – software development is obsessed with the idea of expertise. As individuals we aim to present ourselves as experts while companies fight to employ visible experts and present their brand as most knowledgeable. [...]

What actions and modules can I use to make my CPAN module work on as many platforms as possible on as many perl releases as possible without people complaining it doesn't work on their system.

The * operator is not only a multi-faceted magic spell that (for the uninitiated at least) lends confusion to any example utilizing it ... it is also a clearly delineated compiler transform! This talk cannot promise to make you fall in love with the expression ‘my $biggener = * * * * *’, but it may just convince you that such an expression is something of a modern marvel of programming.

A comparison between the seemingly-different languages of Perl 5 and Scheme, looking at where they are similar and where they diffe

comparing IO::Select in perl5 to react/whenever in perl6 for implementing a super tiny chat server (telnet/netcat client)

Having fun explaining a bit more than the basics of functional programming and how the syntax and implementation is done in Perl 6 - sometimes comparing it with Perl 5

REST api's are perfectly well designed to GET information from a server. With Content Negotiation, one can even let the server know what format the data should be represented, json, xml, html, or any other. It also allows the client to specify what language it accepts the data returned.
