You Attended Talk: an introduction to event sourcing

Imagine for a moment you work for a large online retailer specialising in household goods.

Being Functional in PHP

Functional programming, though far from new, has gained much traction recently. Functional programming characteristics have started to appear in the PHP world, too. Microframeworks such as Silex and Slim, middleware architectures such as Stack and even standards such as PSR-7 rely on concepts such as lambdas, referential transparency and immutability, all of which come from […]

Hopping in clouds: a tale of migration from one cloud provider to another

Nowadays there are a lot of cloud providers, with a wide range of offers. Web projects usually have continuously changing needs: what worked well yesterday may not be enough today.

Context Oriented Architecture: put the boundary in the right place.

Last year the hype was on SOA, today is on the Microservices Architecture, what about tomorrow? No one knows. Whatever it is the architecture you want to use, we probably agree that the strategic goal of a tech team is to support a company business, creating customer value. How can we model our software and […]

How I learned to stop worrying and love Regular Expressions

This session will cover Regular Expressions from the basics to the darkest corners of this arcane art. Regular Expressions at the core come in handy to achieve validation and text manipulation tasks. In the day to day life of a developer, becoming comfortable with them opens up many more use cases. As one of the […]

Denser, Cooler, Faster, Stronger: PHP On ARM Microservers

This is the story of how I helped make run on a small collection of state-of-the art ARM-based microservers, and the lessons I learned along the way, from how not to crash your entire multi-node MySQL database several times a day, to how not to have nginx consume all your disk space within a […]

More devs on devops with Docker Orchestration.

The Docker tools are the new era to build, deploy and scale applications easily. After more than one year of using this technology in production I’d like to share the benefits and disavantages of having docker in both env (development and production), the bad and good practices all the workflow to speedup deployments, and how […]

Keep your users up-to-date in realtime with WebSockets!

Live document collaboration, playing cooperative and competetive games, updating sports scores, booking seats. Stateless and belated nature of HTTP requests is not a perfect match for these and other similar use cases. WebSockets offer immediate delivery of messages in two-way communication between the client and the server. Instead of periodic polling for new messages, they […]

Machine learning for PHP

Machine learning is teaching the computer how to learn by itself. It is far easier to be done, especially when you have small data set and a good level of expertise in your field. Classifying objects, predicting who will buy, where to park your car or which test will fail may be achieved with grassy […]

Beyond PSR-7: The magical middleware tour

PSR-7 has made its way to become a PHP standard. The Middleware word – at the same time – has become one of the most prominent buzzwords of our ecosystem. Are we facing a bust here? Wasn’t PHP invented for the web? So, what is this fuss all about, if we’re actually only dealing with […]

PHP 7 performances from PHP 5

PHP 7 is incredibly faster than PHP 5. In this talk, we will compare profiling of applications against PHP 7 and PHP 5, and point some scenarios where PHP 7 really outperforms PHP 5.
