Neat lil learning from today’s @PerfNowConf (via @umaar):

You can now throttle individual requests in Chrome!

Neat for experimenting with stuff like
- lazy-loading: does the UI look okay if this chunk takes MUCH longer to arrive?
- resilience: what happens if this specific CDN is extremely slow?
- etc

@sindresorhus @npmjs @github @feross Might npm package provenance help in the future?

Feels like this whole community depends on your packages! Happy to get involved if you're looking for help

📢 The Chrome DevTools flame chart has just become *much* easier to use.

I wrote about these new features (for DebugBear), and other new DevTools features you probably didn't know about.

Claude 3.7 drawing pelicans with SVG

Noticeable improvements with each new model

> Generate an SVG of a pelican riding a bicycle. Make it look like the pelican is riding the bike with an animation. Also make the bike do a wheelie every few seconds

Playing with a new LLM benchmark: how good are they at drawing an SVG of a pelican on a bicycle?

@wesbos 20x CPU throttling is a pretty helpful for catching perf issues on a fast machine

[Umar Hansa @umaar]

@wesbos Another powerful workflow: devtools remote debugging + port forwarding, so you can view localhost urls on your mobile device

@wesbos Being able to easily toggle css utility classes is very handy.
