May 30, 2015 — 2015 will be remembered in the WordPress community as the year of the JSON REST API. It will be the biggest turning point in the WordPress project since 2010 (when we first saw custom post types). As a result of this, I believe that we’ll see /wp-admin start to disappear in favor of more functional backend interfaces. In this talk we’ll explore the possibilities of a future without /wp-admin

May 30, 2015 — Nous commencerons par un survol des requêtes que WordPress fait lors de la préparation du contenu d’une page ainsi que de la boucle qu’il traverse pour préparer le HTML puis nous finirons avec une boucle d’affichage d’un objet très spécifique. Nous verrons aussi comment « expliquer » à un engin de recherche comme Google ce que nous lui présentons avec des attributs qu’il saura comprendre. Cette présentation ne s’adresse pas seulement à des développeurs de thèmes. Si vous êtes un utilisateur qui se concentre uniquement sur le contenu du site, je vais vous armer de concepts et d’outils permettant une meilleure communication avec vos développeurs.

May 30, 2015 — One of the recent WordPress accessibility initiatives has been the introduction of the ‘accessibility-ready’ tag for theme authors who wish to submit themes to the WordPress repository. The tag is used to indicate that a theme contains the best practices in web accessibility, and can form the basis of an accessible WordPress website. But uptake has been slow. This presentation looks at what you need to do to get your themes up to the ‘accessibility-ready’ standard – whether or not you intend to submit them to the repository. It’s not hard to do, and the benefits can be enormous for many, many people.
I will also be looking at whether it’s worth following the ‘accessibility-ready’ steps for plugins too.
