Building High Performance Websites


06/01/2014 | Arne Blankerts, Stefan Priebsch

Response time is crucial – not only for online stores. But what if the performance is lacking? Buy more powerful servers? Migrate into the cloud? Add yet another layer of caching or blame the under powered database? All possible options, but before you make your hardware vendor happy you should reconsider your software architecture! This session will acquaint you with ideas for a high performance software architecture which let you scale from single server to cloud.

A Framework Is No Architecture


06/02/2014 | Stefan Priebsch

Frameworks solve common problems, and thus allow rapid application development. Agile and incremental software development, however, does not magically create architectures as you go. We will prove the point that your favourite framework does not provide you with an application architecture, and analyze what implications this has. This talk is not about big design up front, and not about "your framework is bad", or "another framework is better". It is about avoiding to end up in a situation where software works, but maintenance is tough, expensive, and bears more risks than you can afford to take, regardless of which framework you are using.

Code Coverage: Covered in Depth


06/02/2014 | Sebastian Bergmann

It is said that the beauty of testing is found not in the effort but in the efficiency. Knowing what should be tested is beautiful, and knowing what is being tested is beautiful. Code Coverage, which is a measure used to describe the degree to which the code is tested, can help with the latter. PHPUnit has had support for code coverage analysis for a long time. This is one of the features that is extended and improved with each release of PHPUnit. This session, presented by the creator of PHPUnit, will cover all aspects of PHPUnit's code coverage functionality in depth. Attendees of this session will learn how to leverage this important functionality more effectively to augment and guide their testing effort.

Which framework?


06/02/2014 | Stefan Priebsch

Developers usually have their favourite framework. But when did they choose it, and why? Was the decision rational, or rather emotional? This talk will not name "the best framework", but rather give the attendees a good background on how and why to choose frameworks and third-party-code in general. Topics covered include code quality, metrics, sustainability, and performing a general project assessment.

Why, What, and How: Testing in 2014


06/03/2014 | Sebastian Bergmann

One of the most important tasks in software testing is to find the right scope for each test case. What can be covered with unit tests and when are system-level end-to-end tests useful? What are functional tests, integration tests, or edge-to-edge tests? How do you test non-functional aspects such as performance? And where do experiment-driven and test-driven development fit in? Attendees of this session will learn which aspects of an application should be tested and how to efficiently implement these tests so that they are easy to write and fast to execute while delivering highly reliable results.

The Flip Side of Dependency Injection


06/03/2014 | Arne Blankerts

Object-Oriented Programming inevitably leads to dependencies on other objects; a problem commonly resolved by applying Dependency Injection (DI). But not every implementation represents an ideal solution for every reality. In this talk, Arne Blankerts discusses factories and locators while demonstrating common mistakes when using so-called "dependency injection containers". Programmers are provided with a more comprehensive view of Dependency Injection.

HHVM: The New PHP?


06/03/2014 | Stefan Priebsch

Facebook has scaled their service to over a billion users, which is very impressive. At some point, however, PHP became their bottleneck. Turns out that rewriting over a million lines of code, even in another language, is not a viable option. So if you cannot change the application, why not change the platform? That is exactly what Facebook did when they created HipHop. HipHop was great, but ultimately failed. Now, the new kid on the block is HHVM, an alternative runtime for PHP. Will HHVM replace PHP? Should you care? Sketching out the history of the project, and its potential future, we will look not only from a technical point of view, but also analyze the business impact.

HHVM: The Alternative PHP Runtime


06/03/2014 | Sebastian Bergmann

The PHP language is almost 20 years old, as is its reference implementation that can be downloaded from PHP.net. In the last decade, alternative runtimes for PHP came and went. The HipHop VM (HHVM) that is developed – and used in production – by Facebook, however, is probably not only here to stay but very likely going to influence the future of PHP considerably. High time to have an in-depth look at what HHVM is and how it works.

Goodbye LAMP Stack?


06/03/2014 | Arne Blankerts

The LAMP stack has been the tried and true backbone of the web for almost two decades. Lately though, more and more websites replace Apache HTTPD with nginx and move from plain (My)SQL to No(t only)SQL. And now it's time to get ready for a new heart: HHVM is a powerful new runtime for the PHP language and this session will show you how to get your application to run on it.
