- Asynchronous Programming FTW! :: Sawyer X
The new age is all about non-blocking asynchronous creative responsive deconstructiverefactored decoupled conjectured applications. If you're not on the event loop wagon loop, you're missing out!
What the hell am I talking about? Am I just drunk? How many of the above words are totally made-up? These questions and more will be answered at this talk!
- Rx.pl - Reactive Extensions for Perl :: Ran Eilam github.com/eilara/Rx.pl
A library for composing async programs. Because writing async code is hard, but working with Perl lists is easy. Lets turn events into lists, and reap the benefits:
- Elegant async programming without callback nesting, using operators we all know from working with Perl lists</li>
- Managing and coordinating events, e.g. start an HTTP request when timeout on key press if previous HTTP request was OK and arrived in the last 10 seconds</li>
- Programming with stream transformations, instead of objects and methods-say hello to beautiful functional designs with well defined state and side-effects. Replace boring UML diagrams with fun marble diagrams</li>
- Stop writing and rewriting retry, timeout, throttle, buffer, window, counters, caching, and aggregate functions for each project. Instead create your processes as observables, then enjoy a rich library of existing operators</li>

This meeting was a practical one, focusing on testing. We began with a talk on testing, explaining what tests are, what needs testing, and how to get started with it. We then split up and hack away on tests.

- Binding Shared Libraries with Perl :: Ido Kanner
- Overview of what shared libraries are, and how to bind their functions to Perl.
- Real Time Web with Pocket::IO :: Ynon Perek
- The Internet is changing direction. More and more web-sites want to notify their visitors in real time about changes that happen on the server (for instance, a different visitor uploaded a photo). A library called Socket IO unifies all the various ways to send messages from the server to the computers of the visitors and allows the programmer to write an Internet application that gets updated in real time. vti implemented the library in Perl as Pocket::IO. In this talk, I will present the ideas behind Real Time Web, including code excerpts in Perl which use the library in order to create interactive sites.
- Regular Expressions Demystified :: Sawyer X
- Do you use Regular Expressions? No? Would you like to? Do you find them complicated or confusing? Let's try to fix that. A beginner's talk for introducing simple, smart, easy-to-understand Regular Expressions.

Instead of the usual technical meeting, we will have a hackathon!
We could work on contributing to projects, fixing or adding features to existing projects, starting new projects, trying out different stuff we haven't yet, and learn new stuff!
Here are some ideas for what to do at the hackathon:
- rewriting a CGI app in Dancer, or add features to an existing web app
- rewriting an application using Moose
- contributing to a CPAN module (bugs/features/documentation/tests)
- adding a feature to a CPAN module
- writing a new CPAN module
- working on TelAviv.pm.org and automating the tools to update it
May 30th, 2012
- From client to execution :: ik
- This talk will explain what Redis is in a few words, the client Ido has written for it, and which Perl tools are available to use it.
- Perl for Newbies, Part 5 :: Shlomi Fish
Shlomi will use the audience as guinea pigs for testing and verifying the
fifth part of his series of talks, Perl for Perl Newbies, whose theme is
"good programming practices". The slides cover such topics as writing
automated tests, using version control systems, using class accessors,
writing documentation using POD, and using Module-Build and Module-Starter.
Shlomi's slides are available here
May 2nd, 2012
We are going to have two talks about the two extremes of Perl. After the talks we are going to have a mini-hackathon working on a few CPAN modules.

- Visualizing the brain of Vim :: Ran Eilam
- You loved him in "Game frameworks with SDL, Moose and Coro", you cried over his performance in the after-meeting get-togethers, and you will absolutely adore him in "Visualizing the brain of Vim". All-star legend Ran Eilam will talk to us (both beginners and experts) about Vim and how to fathom this incredible beast. I warn you, the first two lines in the audience will be damaged by Emacs flames.
- A bunch of modules which made sense writing :: Sawyer X
- I'm going to cover some utility modules I've written, why they were written and when they are useful. At the end, you'll have to judge whether they were worth writing at all. There will be voting booths available! (We'll cover Algorithm::Diff::Callback, App::Genpass, Data::PowerSet::Hash and Module::Version.)
- To upgrade or not to upgrade, Perl 5.6 vs. Perl 5.14 :: ik vs. Sawyer X
- A source of great concern in the Perl users community is whether to use an up-to-date Perl and what version should be considered "too old". On one hand, we have the management that wants as little cost and changes as possible <>(sometimes along with systems administrators), and on the other hand, the> developer who wants to use the latest technologies, and is often stuck on obsolete systems. In light of this serious consideration, we're going to take turns poking at each other with a stick, wearing funny hats, damning the unbelievers and heretics until they submit to one side: 5.6 or 5.14!
November 30th, 2011
- Tools of the Perl, a quick survey of 4 modules :: Erez Schatz
- We will cover four modules that make the life of a Modern Perl developer much easier than it used to be: local::lib, cpanm, perlbrew, pm-uninstall.
- DBIx::Class and ORMs :: Erez Schatz
- What is an ORM, why do we need it, and what does DBIx::Class bring to the table for Perl programmers at large.
- Firebird: a database that does not burn your data :: ik
- An introduction to the Firebird database and why it is so highly-regarded by those who use it.
August 31st, 2011
- Git :: Sawyer X
- Git is a decentralized code revision management system. It's becoming a valuable tool for developers (whether programmers, designers, or other) and is spreading like fire due to its useful nature, being used in the Linux Kernel development, many free software libraries and programs and many organizations alike. I intend to teach it to you. :)
- Gitflow :: Sawyer X
- Gitflow is a useful wrapper tool to allow you to set a more streamlined development process, taking into account features, releases, hot fixes and more. It's very useful when using multiple developers with an integrator, a QA, a dev team, and so on. I intend to showcase it as well!
July 27th, 2011
- How to write a module and package it as a CPAN (like) distribution :: Gabor Szabo

- Scraping A Cookbook :: Ynon Perek
I recently got a chance to convert a live web site
<>(http://www.anonymous.org.il) into an iPhone app. The process involved deciding>
which parts will go into the app, how it will look, and scraping the content to
an SQLite db that was to be deployed on the iPhone (along with an app).
In the talk, I will present some of the perls I used to get/convert the textual and image data, and use them to talk about XPath, DOM and SAX for digging the "right" data.
- #myjourneytoperl - graphing a meme :: Dotan Dimet
- On March 30th, at the urging of Matt Trout, Perl people on Twitter posted text graphs showing their path to Perl from and through other programming languages. Inspired by the directed graph format used, I decided to capture these posts and combine them into a single giant graph which I would render using the GraphViz toolkit. I'll talk about the tools I used (Mojolicious, GraphViz, the witter JSON API), the problems I encountered (Unicode!) and the snapshot of the Perl community that emerged.
- Writing a blog engine in 15 minutes :: Gabor Szabo
- It will be especially easy for people who are using Windows as they can download a single package that have everything they need. We will create a Dancer based web application and then allow a single user to create blog posts.
May 25th, 2011
