I always like seeing how other folks handle performance audits. Here, Jake walks through 10 F1 sites, auditing them primarily with WebpageTest and a smattering of Chrome Dev Tools.
Academic background or not, technical education doesn’t stop once you get a job. On the contrary: nothing in tech stays in one place, and the single most valuable skill you can possess to remain employable over time is learning how to learn.
Some great advice here from Sarah on learning.
Handy little reference from Addy Osmani showing how Chrome handles JavaScript scheduling.
I’ve being using preload with clients over the last few years but I have never been completely satisfied with the results. I’ve also seen some things I hadn’t quite expected in page load waterfalls so decided to dig deeper.
Excellent work digging deeper into preload by Mr. Davies.

A very approachable explanation from Sarah about what Hooks are and the problems they solve for Vue.

While ever you build under the assumption that things will always work smoothly, you’re leaving yourself completely ill-equipped to handle the scenario that they don’t.
