Meanwhile, the mobile web gmail UI m.gmail.com is so fast and delightful, despite being ~unmaintained for 10+ years.

You'll probably appreciate the mobile web gmail UI: m.gmail.com Sadly, it now requires a mobile UA. But despite being ~unmaintained for 10+ years, it's so fast and delightful.

Gmail

Gmail is email that’s intuitive, efficient, and useful. 15 GB of storage, less spam, and mobile access.

Some discussion in

But.. it seems like not many advocates for 'upsert' itself. ¯\_(ツ)_/¯

Rename from "proposal-upsert" to "proposal-getorinsert" · Issue #83 · tc39/proposal-upsert

Generally "upsert" means your updating or creating. But this method seems to be getting or creating. Consider renaming this proposal from "proposal-upsert" to "proposal-getorinsert". https://x.com/...

This is hot. And aligns with some work I've been hacking on. Can I give it a whirl?

Prompts as MCP payloads are def not getting much attention but I also think they have good potential.
Interesting that Claude doesn't act on the prompt response type without extra nudging.. especially since this is all their design.

Weirdly buried in the article:

The Nashville chief federal prosecutor (who'd lead this case?) decided to resign in protest over this case being pursued for political reasons.

The decision to pursue the indictment against Abrego Garcia led to the abrupt departure of Ben Schrader, a high-ranking federal prosecutor in Tennessee, sources briefed on Schrader's decision told ABC News. Schrader's resignation was prompted by concerns that the case was being pursued for political reasons, the sources said.

Schrader, who spent 15 years in the U.S. Attorney's Office in Nashville and was most recently the chief of the criminal division, declined to comment when contacted by ABC News.

Sometimes I let my website draw pictures in the Profiler

DevTools Perf panel open against paulirish.com. A bitmap representation of the poop emoji is displayed in the profiler. (It was done with a lot of performance.measure() calls)

My talk from I/O: a 10min jaunt jam-packed with DevTools Performance panel goodness. youtu.be/BHqxD9qr6Gw

Really proud of what we've landed in the past year, including JS bundle analysis, framework tracing APIs, auto-annotations, CrUX context, and deep insights.

👀 Coming to Chrome DevTools in Chrome 138: CSS Value Tracing

When you hover a --custom-prop in a `var()`, DevTools currently shows you the computed value. From Chrome 138 onwards, you can hover the `var` part to see how CSS actually got to that value.

100%. Applescript is super painful. Finding what API is exposed by each application.. Trying it out.. Logging. All of these things are just terrible. But yeah I don't know other mechanisms to query some of this.

Here's my version of the same dealio. A lil ffmpeg/fzf/applescript/fish combo to screencapture the bounds of your chosen application's frontmost window. gist.github.com/paulirish/c1...

The next biggest win is getting rid of the 3 render blocking requests. That'll give the LCP a 1.3✕ speedup.

(Btw it's quite fast! Nice job)

Been annoyed by web fonts for a while. They’re big and they were connecting my blog to Google.

I stumbled on modernfontstacks.com earlier today and now I’ve ditched my web fonts in favour of these.

~140kb shaved off the first load of my site. First impressions matter.

Modern Font Stacks

System font stack CSS organized by typeface classification for every modern OS. The fastest fonts available. No downloading, no layout shifts, no flashes — just instant renders.

Is the WebDev Arena truly measuring webdev coding ability?

This ML coding benchmark *requires* React/Tailwind and completely breaks with vanilla JS/other frameworks.
The second-order implications of models competing on this narrow definition of frontend web development are rather troublesome.

Screenshot of https://blog.lmarena.ai/blog/2025/webdev-arena/ showing the system prompt, which includes:

> You are an expert frontend React engineer
> - Create a React component for whatever the user asked you to create
> - Use Tailwind classes for styling.
