17 Ways to Undo Mistakes with Git

datasyncer@sandsmedia.com — Mon, 05 Oct 2020 13:42:36 +0000

We cannot avoid mistakes. But with the right tools, we can make sure they don’t hurt too much. Git offers many ways to undo, revert, recover and fix. We’ll look at the bad things that can happen to you – and how Git can save your neck.

In this hands-on session, we’ll have a look at Git’s various "undo" features. My intention is to give developers more confidence in their day-to-day operations when working with code: "mistakes can be undone" is something I’d like the audience to keep in mind. In the session, I will both talk about the theory and show the corresponding commands / tools in practice. I’ll be using both Git on the command line and the popular GUI "Tower" to show how to deal with mistakes in real-world scenarios.

Layers, Rings, Onions – Hexagonal and Clean Architecture for Better Code

datasyncer@sandsmedia.com — Fri, 17 Jul 2020 08:11:11 +0000

Technical code and business code should be kept separate. That seems like a simple architecture rule. But it is violated in virtually every real project. Even the current versions of frameworks like Symfony, Laravel, and co. easily contaminate our domain models. In this talk we look at ways out of this plight. The architectural styles...

Lessons learned from building Sulu 2.0

datasyncer@sandsmedia.com — Wed, 19 Feb 2020 06:51:13 +0000

After more then 2,5 years of development we have finally released a new major release of our OpenSource Content Management System build on top of Symfony. That’s a very long time, and we have totally underestimated how much work it will be. However, this allowed us to learn a lot of different lessons, from many different areas. Some concern how to plan such a project, how to handle certain restrictions or software architecture. In this talk I would like to tell you about as many as of these lessons as possible.

WordPress for Modern Developers

datasyncer@sandsmedia.com — Thu, 13 Feb 2020 10:59:40 +0000

WordPress may poser a third of the web, but it’s one of the world’s most popular legacy projects. So if you’re a modern web developer but you’re forced to use WordPress, what are your options?

This talk explores the tools and frameworks that are available to enable modern development in a legacy project, and how to make WordPress development feel like working with a modern framework. It also explores just how far you can push the “magic” of WordPress when it comes to theme development.

Reformat, Refactor, Replace

datasyncer@sandsmedia.com — Thu, 13 Feb 2020 11:59:39 +0000

When your everyday grind is a monolithic, legacy, PHP application from the early 2000s, it can be hard to utilise the newer tools and technologies that are available. Fortunately, there’s a process you can follow to get your application up to date without losing customers, business logic, or your mind. This talk covers the tried-and-true...

Create a WebSocket server in PHP, is it possible ?

datasyncer@sandsmedia.com — Tue, 11 Feb 2020 13:37:59 +0000

Today, WebSockets are more and more used in our projects. The real time they bring us allows to respond to new usages, to differentiate ourselves with new features. They are commonly tied to the Node.js and JavaScript ecosystem. Do you know it’s possible to create a WebSocket server or client using PHP ?

What are the available solutions ? Why do I need to create my own server/client ? Is PHP the right tool for that job ?

This talk’s goal is to present the current state in the PHP ecosystem and show using a real example how to build a viable implementation. Then, like we often heard, everything depends on the context, you are free to use that kind of tool in your project … or not !

PHP in 2020: Fully Loaded

datasyncer@sandsmedia.com — Wed, 11 Dec 2019 13:31:30 +0000

Does your application rely on autoloading? Chances are, it does – given autoloading was introduced to PHP back in Version 5. While the original global function has long been deprecated, since PHP 7.4 the whole concept of autoloading became superfluous. This talk will introduce you to the new preloading mechanism and how it is likely...

PSR-14: A Major PHP Event

datasyncer@sandsmedia.com — Wed, 11 Dec 2019 13:31:30 +0000

PSR-14 is the latest specification from the PHP Framework Interoperability Group (PHP-FIG), this time addressing event dispatching. Many frameworks and applications contain an "event dispatcher", "message bus", "hook system", or some other variation on the same basic concept, but to date they are all incompatible with each other. No more! The PSR-14 spec offers a way to interweave these disparate systems, making it far easier to swap individual libraries into the framework of your choice. It goes beyond the basic "register and call" object that most systems use to make it easier to plug different implementations together, offering an easier experience and greater flexibility for library authors. This session will cover how PSR-14 works, some examples of how to leverage it effectively, and how to adopt it alongside, and even encompassing, your existing one-off tooling.

How Much Framework? #slideless

datasyncer@sandsmedia.com — Wed, 11 Dec 2019 13:31:30 +0000

Choosing a framework is not an easy task: How good is the documentation? How many developers are actively working on it and how long has it been around? Interesting and valid questions but not necessarily the most important ones. How much of a framework do we actually need? And how crucial will it be for our application? In this session, we’ll try to answer these two questions in a potentially surprising way: by implementing our own micro framework from scratch – in 45 minutes!

Hall of Mirrors

datasyncer@sandsmedia.com — Wed, 11 Dec 2019 13:31:28 +0000

Having done away with "eval()" and "register_globals" we now live in a brave new world of autoloading third-party dependencies, object reflection and comment @annotations. Do you really know what is executed when you run a bit of code and do you even want to? PHPUnit is designed to isolate pieces of code for testing. Together with a debugger, this makes for an excellent sandbox to explore this topic. Using the internals of the testing framework we take a look at how quickly complexity creeps in. Starting with a simple test we explore what happens when complexity is introduced: parameters, dependencies, process isolation and finally reordering of units of work. At every step the testing core has to do more work to hide what is really going on. The talk ends connecting the dots by looking at the architecture and implementation of the execution reordering features, introduction of a state-cache and footprint improvements of data-driven automated tests.
