The Analytics That Matter
25.6.2020
I’ve long been skeptical of quoting global browser usage percentages to justify their usage of browser features. It doesn’t matter what global usage of a browser is, other than nerdy cocktail party fodder. The usage that matters is what users on your site are using, and that can...

5.6.2020
This article is about my experience using Brotli at production scale. Despite being really expensive and a truly unfeasible method for on-the-fly compression, Brotli is actually very economical and saves cost on many fronts, especially when compared with gzip or lower compression levels...
A/B Testing Instant.Page With Netlify and Speedcurve
5.6.2020
Instant.Page does one special thing to make sites faster: it preloads the next page when it’s pretty sure you’re going to click a link (either by hovering over 65ms or mousedown on desktop, or touchstart on mobile), so when you do complete the click (probably a few hundred milliseconds...

Core Web Vitals is what Google is calling a a new collection of three web performance metrics:
LCP: Largest Contentful Paint

Chrome + System Fonts Snafu

I just can’t stop bookmarking great links related to typography. I’m afraid I’m going to have to subject you, yet again, to a bunch of them all grouped up. So those of you that care about web type stuff, enjoy.

Web Performance Checklist
2.4.2020
The other day, I realized that web performance is an enormous topic covering so very much — from minimizing assets to using certain file formats, it can be an awful lot to keep in mind while building a website. It’s certainly far too much for me to remember!
