December 24, 2024 — In my first week on the job, I was tasked with speeding up a site that was incredibly slow. And when I say slow, I mean REALLY slow: 40 seconds or longer to save a single post. 20 seconds or more just to get to the post editor.

We dug through endless lines of code.
We read some fantastic resources on the topic.
We spoke to our friends in the community, who are experts in their respective fields.

The technical details of this talk include:

xhprof with a custom addition that I wrote.
The filter ‘posts_clauses’.

December 24, 2024 — Tijdens WordPress Meetups en andere WordCamps is er genoeg gesproken over toegankelijkheid. Hoewel inmiddels velen dénken dat ze toegankelijkheid wel doorhebben (dat is iets met kleurcontrast toch, en zinvolle linkteksten?) blijkt dat in de praktijk niet zo te zijn. Ik wil laten zien waar toegankelijkheid echt over gaat, voor wie het verplicht is om toegankelijke websites en apps te hebben, en hoe dat er in de praktijk uit ziet.

December 24, 2024 — Stel je je website voor als die rugzak die je altijd bij je draagt: vol met bonnetjes, ongebruikte gadgets, kabels en die zware powerbank.

In deze talk geef ik je tips hoe je je website kunt verbeteren door flink de bezem te halen op het gebied van ontwerp, teksten, afbeeldingen, navigatie, plugins en onderhoud. Dit minimalisme maakt niet alleen je bezoekers blijer, het draagt ook bij aan een duurzamere online wereld.
