Les outils de tests automatiques d’accessibilité peuvent malheureusement faire mal alors que ce n’est absolument pas le but. Entre les déclarations d’accessibilité affichant un score d’un outil de tests automatiques et les entreprises vendant des prestations d’accessibilité alors qu’elles ne font que vérifier leur travail avec ce genre d’outil sans aller plus loin, on voit vite les travers du score que ces outils affichent. Un court article pour dire ce que j’en pense.

When starting on a web performance journey, many companies’ first step is to start monitoring performance metrics over time. But the second step is often much harder - now that you have all of this data, what do you do when you see a regression? How do you sift through the clues to connect a change in a graph to the code that engineers ship to production? How do you become a performance detective? In this session, Katie will crack open her casefiles to share some real-world examples where performance metrics changed for the worse, and walk through how to find the culprit. You’ll learn what clues to look for to understand a regression in your Core Web Vitals, how different performance metrics influence each other, and when to use data gathered from real users vs. synthetic tests in the lab.

To serve users at the global P75 of devices and networks, we can now afford ~150KiB of HTML/CSS/fonts and ~300-350KiB of JavaScript (gzipped). This is a slight upgrade on last year's budgets, thanks to device and network improvements. Meanwhile, web developers continue to send more script than is reasonable for 80+% of the world's users, widening the gap between the haves and the have-nots. This is an ethical crisis for frontend. Meanwhile, the most popular tools and frameworks remain in stubborn denial, but reality is not moved by ignoring it: when digital is the default, slow is exclusionary.
