Session topic: Performance patterns for difficult situations
Tatiana is an independent American designer who works directly with organisations to build clear and coherent products and design systems. She believes the trifecta of performance, accessibility, and inclusion can work symbiotically to improve our social landscape digitally and physically. When ethically-minded, she thinks technologists can dismantle exclusionary systems in favor of community-focused, inclusive ones. Never totally pleased with design tools, she designs in browser to visual narratives into the web in a semantic and component-orientated way. Her current obsessions are optimising variable fonts, converting raster images into to SVGs, and recreating modernist paintings in CSS grid. When she can successfully escape vim, she finds new countries to explore (33 and counting).

Some of the most cutting edge and effective web performance optimizations, like prefetch and preconnect, involve being proactive. We make predictions to determine where a user is likely to go next and load resources ahead of time so page load is as fast as possible. This is where machine learning comes in handy. By training a machine learning model (maybe a markov chain?) with current analytics data, we can take the guess work our of our predictions and more accurately load resources ahead of time. In this talk, we will examine techniques currently being developed, like GuessJS to make predictive prefetching a reality.
