Talk I've given at True North PHP 2014.
TDD (Test Driven Development) is getting more and more popular. But what can you do to take it to the next level?
What if you could know if your tests are passing every time you save a file without taking your hands off the keyboard. This is what continuous testing gives you.
In this session, we will cover how you can continuously test your PHP application. We will cover
Installation and configuration
Running the tests
Running static analysers
Executing tools that can make your life easier
Talk given in French at ConFoo 2015

Finding and fixing bugs is a major chunk of any developers time. This talk describes the basic rules for effective debugging in any language, but shows how the tools available in PHP can be used to find and fix even the most elusive error
Puppet Module Reusability - What I Learned from Shipping to the ForgePuppet
A simple search for "puppet-apache" on GitHub returns 70 separate repositories. An awful lot of people are busy reinventing the same configuration wheel. Configuration management tools promise write once, run anywhere code; but writing code that can be used by anyone looks like a lot of work. This presentation aims to show anyone familiar with Puppet how to write reusable modules and importantly how to make them compatible with already shared modules released on the Forge or elsewhere. We'll look at when and why testing a declarative language is actually useful, examples of good and bad modules and how to re-factor puppet code for re-usability. We'll also talk about potential improvements to Puppet that would make reuse easier.

Vagrant + Rouster at salesforce.com - PuppetConf 2013Puppet
"Vagrant + Rouster at salesforce.com" by Conor Horan-Kates
Senior Member of the Technical Staff, Quality Engineering, salesforce.com.
Speaker Presentation: Rouster is an abstraction layer between you and Vagrant. At salesforce.com, we're using it to assist in running functional tests of the Puppet code we've written. While RSpec is significantly faster, it really only tells you whether the catalog contains what you expect it to - not whether those things can/will be applied successfully - and that's where Rouster comes in.
Currently the library contains many hooks for system level testing and information gathering (is_file?(), is_user_in_group?(), is_service?()) and puppet related functionality (get_catalog(), parse_catalog(), run_puppet()), but we're looking to expand.
Speaker Bio: Conor Horan-Kates is a Senior Member of the Technical Staff in the Quality Engineering organization supporting Data Center Automation. In this role, Conor has planned and implemented test environments, created testing and development best practices and developed applications, automated tests, and test frameworks. Most recently, Rouster, an abstraction layer for Vagrant. At salesforce.com, Conor has been involved in many aspects of building the infrastructure, from initial contributions to a CMDB, testing of switch/load balancer/ACL creation automation and now, bringing the build and maintenance lifecycle into Puppet. Additionally, he has written a testing framework that interfaces with salesforce.com records, Test::More::Salesforce, and a learn-by-testing project called Perl::Koans. Prior to salesforce.com, Conor worked in QA at the antimalware company Webroot.
Using Puppet to Create a Dynamic Network - PuppetConf 2013Puppet
"Using Puppet to Create a Dynamic Network" by Thomas Uphill Infrastructure Analyst, Costco Wholesale.
Presentation Overview: Complex networks often need complex configurations and a lot of care and attention to individual severs. Using hiera, exported resources, custom facts, defined types, augeas and some forge modules we will explore the possibilities for having puppet take care of the complex configuration. We'll start with a few simple examples of exported resources and scale up to having hiera key off custom facts and having exported augeas resources build configurations.
Speaker Bio: An early adopter of puppet, Thomas has been using puppet since 0.24. He started with puppet for workstation management at the Institute for Advanced Study where he also helped develop the Springdale Linux distribution. He currently works with puppet at Costco Wholesale Headquarters In Issaquah Washington. He has been working with Red Hat systems since 7.3 and currently holds an RCHA.

The why and how of moving to PHP 5.4/5.5Wim Godden
With PHP 5.5 out and many production environments still running 5.2 (or older), it's time to paint a clear picture on why everyone should move to 5.4 and 5.5 and how to get code ready for the latest version of PHP. In this talk, we'll migrate an old piece of code using some standard and some very non-standard tools and techniques.

- advanced vagrantfile configuration
- vm configuration tips for dev environment: performance, debug, tuning
- our wtf moments
- puphet/phansilbe: hot or not?
- tips for sharing a box
Instrumentación de entrega continua con GitlabSoftware Guru
Mostraremos el caso real de cómo tenemos implementado en nuestra empresa el flujo de desarrollo para integración y entrega continua, instrumentado con GitLab.
Sesión presentada por David Padilla en SG Next 2017
Code testing and Continuous Integration are just the first step in a source code to production process. Combined with infrastructure-as-code tools such as Puppet the whole process can be automated, and tested!
Everyone talks about raising the bar on quality of code, but it's always hard to start implementing it when you have no clue where to start. With this talk I'm showing that there are many levels developers can improve themselves by using the right tools.
* Syntax checking with PHPLint (php -l)
* Validating code with PHP_CodeSniffer
* Testing code with PHPUnit
* Debugging code with XDebug
* Documenting code with PHPDocumentator
* Building with Phing
* Packaging with Phar
Grâce aux tags Varnish, j'ai switché ma prod sur Raspberry PiJérémy Derussé
Le moyen le plus rapide d'obtenir une réponse d'un Backend est de ne pas l'appeler ;-) Une solution fournie par les "reverse-proxy" me direz-vous, mais pas si simple d'invalider le cache...
Ce talk aborde une fonctionnalité méconnue de Varnish: les tags. Nous verrons comment en tirer partie via les "event listeners" d'une application Symfony standard. Au menu, un cluster de Rasberry Pi, une API, et des données toujours fraîches sous la milliseconde.
Backdooring the web is the cheapest and most hidden way to achieve
persistence on a compromised network, both if you're looking at
privileges on the webapp itself or at executing command to underlying
system.
During the talk, we will discuss the context of a web backdoor: the
environment where she can born and grow up will be defined.
Each environmental aspect will be thoroughly analyzed: where is the best
point of injection, why we choose a specific function or trick, what
permissions are needed, how to trigger the backdoor in a safe, hidden
and reproducible way, and of course what to inject.
The talk will thus present several ways to inject obfuscated and hard to
spot vulnerabilities in PHP code. Shown examples will backdoor CMS
plugins as well as custom code, altering the code and polluting the
webapp ecosystem (read: DBMS and webservers).
Practical tips for dealing with projects involving legacy code. Covers investigating past projects, static analysis of existing code, and methods for changing legacy code.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
