On Saturday, April 16th 2005 I did a very foolish thing.

A few git usage tips i've picked up over the years. From utility scripts to actual git commands and general workflow. This will focus on the command line usage of git, rather than any particular GUI

Including a perl one, well - sort of

The talk presents the implementation of a local

I will be telling the story of Calendis , a CRM for SME-s. I will describe the challenges the team encountered in using Agile , testing traction channels,

Agent based models can be used to represent complex systems in biology and social science. Normal economic models suck, so there is a need for them. Most libraries are written in Java and re-used for everything; if Perl programmers jump in, our creativity and Perl's ease of use could change the whole game

Amusewiki is a wiki engine and publishing platform focused on high quality output, powered by Catalyst, DBIx::Class and Git, which tries to focus on the texts hosted and on the reading experience of the user, offering each text in PDF and EPUB, allowing the creation of collections.

Announcing a Perl 6 book

"Professional Flow Chart & Diagram Software" ... almost text mod

This talk introduces Weasel, a new webapp testing library shaped after - and improving on - php's Mink. With it's integration into Test::BDD::Cucumber (pherkin), extensibility and out-of-the-box features such as screenshot and test log recording, it makes for an easy to use platform for BDD style browser-based webapp testing. A spin-off from the LedgerSMB project.

Larry Wall once described programming as a ballistic process -- we aim for a target, run our attempt, see where and how we missed, adjust our aim, run again, ad nauseam until we hit the target. As an example, the Perl 6 module called Terminal::Print now has the capability to handle async printing -- and it only took three full rewrites to get there! [...]

This talk aims to give/explain some lessons learnt and tips on using

Developers and their managers have various ideas about what code review should involve and what it should avoid.

Telegram is an app for secure instant messaging, which provides a great API for building bots. I will go through its main API functionality and will demonstrate some examples of real bots that I use in my practice.

Perl Catalyst is a modern, MVC (model-view-controller) development framework for building the server side of your web application. Its also been around for a while (its in its 10th year!) and the current tutorials, books and various online documentation don't make it easy to see the distilled wisdom of the ages. [...]

With CSV being a dataformat that does not define the variables required to parse it (encoding, separator- and quotation character), we'd like to have features that wil (try to) do so for us automatically.

The talk is getting people interested to create front-end using Angular 2 and Catalyst Framework backend, and deploying to on Heroku

In the past year, I noticed that the way people look at Perl and treat us Perl-people has changed. Instead of "I thought Perl is dead", or "Perl is dead", or "Perl should die" or even "All of you f&^%$king Perl-people should die now" we now even get compliments on Perl 5.24 and Perl 6

Closing Note

How do we document code?

( for the recording on youtube please click on the [ Talk ] link further down, for feedback on Perlmonks please click [ Abstract ], there you'll also find all links and discussions / Please! Don't send me emails use Perlmonks to share the discussion! : )

We've all done it. We've all written code that displays horrible things like "1 message(s) waiting" or "0 error(s) occurred.". It's not that it's particularly hard to get it right, it's just so incredibly tedious.

I'll tell about my experience in developing and optimizing of a Perl program on Raspberry PI (model B), showing how I managed to reduce run time of an XML parser from 30 to 1 seconds

At the London Perl Workshop 2014 we demonstrated how to combine functional programming (for syntactic sugar) and a macro mechanism (for speed) to extend Perl in a "smarter" way.

A quick walkthrough of some XS modules focused on spee

Devel::QuickCover is a Perl module written in XS, which gathers run-time code coverage information with very little CPU and memory overhead, so it is perfectly possible to use it with production code. I will explain how the module is implemented, what you get when you use it and what you can do with that information. I will close by showing some examples of actual usage at the company I work for

How much do you need to know about Perl to make people outside the community aware of the fact that Perl is something to love

Imagemagick can do a lot of tricks to automate image processing, as well as it's MagickCore libraries. But how about doing same manipulation just with pure Perl, and using Imager's powerful core as a base?

The dream is real. Perl 6 is out, and regular expressions are better than ever! We'll dream up a language of our own design, and watch Perl 6 parse it and compile it to working Perl 6 code. Spend some time with the author of the ANTLR-Perl6 converter as we go beyond regular expressions into Parser Expressions, and create a working DSL in Perl 6

Show u how to create good indexes for ur highload applications. Tips&Triks, Secrets and advices. It would be interesting for every levels

Last summer a new JavaScript standard came out - EcmaScript 2015 or ES 6. Although this happened more than a year go, it was a lot of fun for me to see that features that are so common for us in Perl world, has finally come to Javascript. And I want to present them to others and discuss a question - if other languages are borrowing from Perl (in some sense), maybe Perl is not *that* dead

Jenkins is a Continuous Integration tool to manage your environment that fires off jobs like cron or when a button is pushed. This talk will walk you through setting up a Jenkins site, complete with slave nodes on the servers doing the real work, and some simple jobs to get a feel for what it can do for you.

The talk presents Karel, once famous programming language taught to children and students. It has been reimplemented in Perl using some state of the art tools like Marpa for parsing, Moo for object orientation, Dancer2 for web GUI, or Test::Spec for testing. Therefore, it can be used to teach Perl, too

MIR (https://github.com/grubert65/Mir) is a Media Information Retrieval System completely built in Perl and still under heavy development (I've just started a few months ago and is basically a one-man-project among many others I carry on). It can fetch and extract text from different sources (web sites, directories, emails,...) and is geared around a distributed architecture so can easily scale. [...]

Bikeshedding is boring, let's go ride our bikes instead

We stopped to use ACT after the first Dancer conference in 2014 due to various failures and of course because using Dancer to shake a web site is way more fun. It was really a big relieve for us. We also intend to make the software behind it as general purpose tool for conferences. I share the features and technical solutions of the Perl Dancer Conference code in this presentation.

Self organized criticality is a model by which systems reach a critical state where small changes can provoke responses of any size in the system. You know, when you try to fix a small bug and all of a sudden you're refactoring a whole 100K line library. Good thing is, this can be measured, and although it looks like it's not good, it actually is an efficient way the systems evolve and change. [...]

Everybody complains that perl dies. But from where is this coming from? Is because technical world is moving too fast and we cannot keep up? Is because we are not agile enough? Is TMTOWTDI the key factor of this? Will we, as Perl developers survive in this world?

Vulnerabilities are essentially bugs that some portion of the userbase will want to experience intentionally. As a result, the handling of "vulnerabilities" is very different from the handling of normal "bugs".

It's a little hard not to be perplexed by Agile proselytizers who intone the "Agile is not a silver bullet" mantra and then proceed to recommend it for everything. They're like developers who recommend Perl for everything and wonder why people don't take them seriously.
