How Math, Science, and Star Trek Explain the Value of Team Diversity

The greatest asset of open source software is the ability to fork and improve.
In this session, Fredric Mitchell
explores the mathematical algorithms and scientific studies describing the advantage of diverse teams.

We’ll dive into existing research and real-world situations that solved complex
problems. We’ll also explore how Star Trek played a pivotal role in being the
allegory for this concept.

Runtime component: The game changer

By popular demand we’re rescheduling this talk from the previous conference.
Tobias Nyholm will show you the
new Runtime component that allows your application to run decoupled from the global state.

Learn how to make your application portable to many different systems without
making any changes. This is especially beneficial for users that want to run
ReactPHP, Bref, Swoole, etc.

Symfony Forms: Advanced Use Cases

The Symfony Form component offers many features out of the box. It covers 80% of
use cases, but how do you deal with the 20% left? If you have read the
documentation, you probably know how to use it. But do you know how it works?

Alexandre Salomé will
show you advanced use cases such as making a list of items sortable, hiding or
disabling fields based on user permissions, etc.

Data Validation models

On daily basics we need to validate data incoming to our application. In this
talk, Marcin Czarnecki will
show you different validation libraries like Symfony Validation or Webmozart Assert.

Learn the difference between syntax and semantic validation, when can you use
deferred validation instead of keeping your object always valid and what libraries
can help you to perform validations in your application.

Dealing with dependency troubles in your Symfony project

When you maintain multiple applications that reuse code, you probably have some
shared library and/or bundle. You probably use third-party bundles/packages
too. Chances are that you run into issues with dependencies, especially now
with PHP 8.1 and Symfony 6.

In this talk, Denis Brumann
will discuss package design principles to avoid dependencies blocking your upgrade
and how Symfony and other popular PHP packages implement or deviate from them and
how it affects users and maintainers.

With these five new talks, we’ve already announced 25 talks for the conference,
covering a diverse range of topics. Visit the SymfonyWorld Online 2021 Winter Edition
website so you can get your tickets for the conference and the workshops.
