Your code are my tests! (Testing Legacy Code)

After years of promoting PHPUnit I still hear it's hard to get started with unit testing. So instead of showing nice step-by-step examples on how to use PHPUnit, we're going to take an example straight from github.

So I've taken the challenge to start writing tests for PHP projects that don't have unit tests in place and explain how I decide where to begin, how I approach my test strategy and how I ensure I’m covering each possible use-case (and covering the CRAP index).

The goal of this presentation is to show everyone that even legacy code, spaghetti code and complex code bases can be tested. After this talk you can immediately apply my examples on your own codebase (even if it's a clean code base) and get started with testing. To follow along a basic knowledge unit testing with PHPUnit is required.

Down the Rabbit Hole

The common mantra is “Community Works”, but does it? How does burning vacation days to speak at a conference “work”? How does staying up until the wee hours of the morning working on a project, just to turn around and go work your day job “work”? Exactly how does community pay the bills each month? Let me show you how it works.

Let’s jog through my career as a programmer. Along the way, we will take a look at how community has not only affected my career in a positive manner; it has been a JATO strapped to my career. I’m just a programmer, not even a great one. If community can help my career, it can help anyone’s.

Shift Left - Find Bugs As Early As Possible

Shift Left is development paradigm centered on the fact that problems are cheaper to fix the early they are found. In web development world where fixes can be deployed instantly, you do not want to wait for the nightly build to pass or for the manual regression tests. Let the machined do what they are really good at. You want to have a system that will give you comprehensive status about the code you’ve just committed. Ideally in less than 5 minutes (the average developer attention span). Despite the fact that PHP lacks the comprehensive quality tooling compared to the compiled languages, this talk will show you how to make it up and do even better with custom designed tools.

You’ll learn how to create robust build system for PHP that will give you the edge in this DevOps world to deploy faster and with great quality. It will save you a bunch of time and enable your team to focus on more creative and challenging tasks. The talk is technical, focusing on topics such as CI, Phing, linters, HHVM, static code quality, unit tests, api tests. There will also be practical tips and tricks to building your own custom tools for fast, static analysis of PHP code for problems such as SQL Injections, incidental DB table locks.

Drupal 8: The Crash Course

One of the most widely-used and mature Content Management Systems on the planet, Drupal runs more than one in fifty websites in the world. However, it has always been something of an odd duck, with an architecture and design very different than anything else in PHP.

Enter Drupal 8: Almost a complete rewrite under the hood, Drupal 8 is a modern, PHP 5.4-boasting, REST-capable, object-oriented powerhouse. Now leveraging 3rd party components from no less than 9 different projects, Drupal 8 aims to be the premiere Content Management Platform for PHP.

But how do you use all this new-fangled stuff? This session will provide a walkthrough of Drupal's key systems and APIs, intended to give developers a taste of what building with Drupal 8 will be like.

Prior familiarity with Drupal 7 is helpful but will not be assumed.

Clean Code == Pure Conscience

What are the fragments that destroy our projects? What are the basic mistakes we all make? What aspects we underestimate in our work? In this talk we are going to find out how not to destroy a project.

During project's development, sooner or later we enter a stage of fighting our own code. Furthermore, such situations can decrease team motivation and can even bring our projects to failure. Sounds familiar?

In other hand, maintaining clean code can significantly improve our speed of development. In fact, developers will benefit from clean code by simplifying their work in long term basis.

In this talk we are going to summarize some clean code principles, discipline, common mistakes, refactoring and more.

Shifting gears with Gearman

Everyone starts with a simple one-machine setup, running PHP(or whatever else you fancy), MySQL/PostgreSql and Apache/Nginx. Sooner or later that will not be enough, you will have more operations to do than can be done in a single request, or you will have some operations that need to be done in parallel, and you will be faced with some important architecture decisions.

This talk will show you how a distributed system built with gearman looks like, and more importantly the strange and wonderful things you will encounter in production and how to prepare for them.

Going crazy with caching: Caching pages of logged in users

You know how HTTP caching works but need more? In this talk we look into ways to cache personalized content. We will look at Edge Side Includes (ESI) to tailor caching rules of fragments, and at the user context concept to differentiate caches not by individual user but by permission groups. A big help to leverage this concept is the FOSHttpCache in combination with either Varnish or the Symfony HttpCache class.

Discovering graph structures

Graph is a mathematical construct used to model the relationships between key/value pairs, comprises a set of vertices (nodes) and an arbitrary number of edges (lines) which connect them. There are many ways to implement graphs with PHP, from typical SQL solutions to dedidacted, powerful tools like Apache Giraph or Titan. In this talk I will introduce Neo4j, highly scalable and robust native graph database, used in mission-critical apps by thousands of leading startups, enterprises and governments around the world. We will also talk about managing nodes and traversing methods with PHP.

Asyncronous data processing

Choosing the right way to process data might become a strategic and non trivial decision for many kind of applications. Especially in applications where an high percentage of the time is spent elaborating informations behind the scenes. A solution could be to use a message queuing system for processing data asyncronously. Using AMQP it becomes possible to define different types of queue patterns in order to solve different types of problems.

The purpose of the talk is to show how to approach the diffentent scenarios in php adding a great value to your application.
