Learning 6 languages at once? Wow! That’s parallel processing at its finest 😉 I’ve never heard of most apps in that list, so thanks! At least when it comes to app-based learning, I was pretty satisfied with Babel and don’t have an urgent need to try something else.

Ever give Babbel a try? It was the best language learning app I've come across after trying a handful.

- CSS Containment can be used to reduce unnecessary rendering work. (Check out my blog post www.speedkit.com/blog/field-t... on a test we did last year, and that we should re-test)
I can’t wait for next year’s Performance.now()!

* The Speculation Rules API is already proving very effective in improving load times in Chrome. But devs need to be aware of pitfalls. (In this vid youtu.be/rz6mpodOPy4?..., my colleague @erikwitt.bsky.social explains how we leverage RUM data for better precision with Speed Kit)

- The Long Animation Frames API in Chrome can be super helpful for identifying bottlenecks in rendering, execution and interaction. That data can also be used to see how user engagement or business metrics are affected. (I’ve found LoAF to be useful for identifying processing hogs)

- Some browser vendors are quicker than others in developing features and tooling aimed at perf optimization. We as a community need to work together to push for standardization across all browsers by actively requesting and testing new features, submitting bug tickets and pull requests.

Here are some of my takeaways:
- As AI continues to influence how we build the web and users use it, we need to be all the more diligent in avoiding slop and bulk, always aiming to create delightful, accessible experiences.

Yes! I played around with it a while ago to see if CSS Containment budged CWV: www.speedkit.com/blog/field-t...
Would love to run some more tests, however!

Nice sleuthing, Harry! 🤩 Good points to keep in mind when debugging LCP. Looks like Lighthouse would have called out the <article> (and a massive render-blocking CSS file) as well.
