How Does Chrome DevTools Network Throttling Actually Work?
Learn what Chrome network throttling looks like behind the scenes and how it compares to system-level throttling with tools like Apple's Network Link Conditioner.

Many developers misinterpret what the DevTools performance test results tell them. My video below explains how Chrome implements network throttling and how it impacts your data.
Neither the bandwidth nor the latency implementation match what you'd see on a real slow network.

Tangentially related to the prevalence of newsletter pop ups… Product looks at the raw numbers of people who’ve signed up for a newsletter, but usually fail to consider the negative impact of an interruption in the shopping flow holistically.

ICYM this post by @cheddybop.bsky.social, it has never been clearer that the legacy frameworks (React, Angular, etc.) will never turn the corner on mobile perf; and mobile is most of the web. The only winning move is to decamp to something *actually* modern:

The web needs a system level “ask app not to track” type of mechanism for set-it-once cookie consent.

Polymer came out right as I finished up undergrad. Used it at an internship and that’s when my love for the web began. I remember setting up Polymer apps with Yeoman, Bower, etc. Such a different era!

Marko 6: Fulfilling the Promise of Less JavaScript w/ Dylan Piercey
YouTube video by Ryan Carniato
There is hate for JS on the server. But none have accomplished what @markojs.com has. Forget Islands, forget serialization boundaries, forget writing code twice. Just declarative templates, low JS, automatically.
@dpiercey.me joins me Friday to show how it's done.

Oh, yes! I remember that one. Incredibly tricky to isolate. Stoked you have a reproducible case! Let me know when the bug report is live so I can follow. 👀

Haven't been keeping up with the webperf slack, but this was in the scrollback from March, and shows so directly how understanding the rendering engine unlocks better experiences for everyone, not just folks on low-spec machines and networks:

I get requests for line clamping. While possible on the web, it’s technically not well supported (understandably)
Not necessarily print, but a byproduct of designing within a static context.

Vue’s “quick start” guide omits routing. vuejs.org/guide/quick-...
They provide guidance for folks looking to add routing. vuejs.org/guide/scalin...
Perhaps it’s not equivalent to CRAs goals, but I like the approach. Their docs also help you understand when a meta framework is more appropriate.

I’ve had conversations with product managers that lead to statements like, “People don’t like the website because it has pop ups, so we want to add an app install banner to help people install the app” 🫠 Making the website bad on purpose is not going to have the effect you want it to have lol

I use this feature when measuring pixels with the built-in screenshot utility. I can zoom in to be more precise without affecting the pixel calculation. One of my favorite little things about using a Mac!

I think a lot about how the principles of design and UX are fundamentally incompatible with capitalism; at a certain point, they have opposing priorities.
That means if you're in the field, your company is paying you to care about something it will never care about. And that's a recipe for burnout.

What does it mean for something to be Turing complete?
I answer this question, and more, through a series of fully interactive Turing machine simulations! Play, pause, step forwards and backwards, and even write your own Turing machine programs in my latest blog post.

Echoing the steel case praise. I use a Gesture at home and a Leap at the office. They are fantastic! The leap is usually cheaper. You can probably find one at an office resale store.
