Presenting the BRAND-NEW season - @dimension20.bsky.social On a Bus! 🚌

DM'd by Katie Marovitch, and as players: Aabria Iyengar, Brennan Lee Mulligan, Jasmine Bhullar, and Mark Mercer!

Wow. That’s super sad to hear. Take care and I hope you’ll have the right mix of calm and distraction over the coming days!

I’ve tried to explain it as “a lot of art is about communication and talking to yourself is just not the same thing”. And I’m saying that as somebody who loves talking to himself on a regular basis.

You can serialize a promise in React Use React to create a promise on the server and later finish it on the client.

New blog post on serializing promises in React. Learn how RSC serializes data between the server and client.

That’s so sad and just doesn’t make any sense. ☹️ Adam’s an amazing voice for the web and its users.

Dark mode toggles should be a per-site browser preference, just like zoom.

Why are we still reinventing the wheel with JavaScript? Let's make dark mode a browser-native feature.

Our toddler discovered “Rock around the clock” tonight and I’m afraid he’s taking the lyrics a bit too literally.

Node.js — Node v23.8.0 (Current) Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Just released Node.js v23.8.0.
It includes an initial implementation of URLPattern, an new flag to load system certificates, zstd, and more!

TIL: it’s easier to implement web sockets from scratch* than to teach various Java clients that bidirectional streaming over HTTP is possible.

I assume it's basically just this (package downloads / global downloads)? jkrems.dev/npmstats/#/d...

I remember @seldo.com showing download stats as “share of registry” which removed some of the general ecosystem growth noise from the stats. Is there some site that offers those numbers today? Raw download counts are super hard to interpret correctly. :(

@soldair.bsky.social I knew it’s been a while since mana burn was removed. Didn’t realize it was in 2009 (!)…

Now just give me string concat in calc and I think we can call the web “done”. 🎉

The long term goal is to standardize the relevant bits where applicable. Gathering the gaps in standardization is just the first step on that long road. :)

The goal is to gather these patterns and properly document them. Hopefully leading to less guess work when publishing libraries or moving between build systems. 🤞

Tools: Common Conventions · Issue #49 · tc39/js-outreach-groups There's a variety of behaviors in authored JavaScript that (web) developers may depend on that aren't described in any officially published spec. This is an attempt to collect them and link to the ...

What are some useful pattern you’d expect to work across bundlers? We’re collecting a list here: github.com/tc39/js-outr...

The race is on: Will I get all post-holiday access issues resolved before the first meeting of the day? I’ll know in about 5 minutes.

Took me a while to find him in the first picture.

I'm starting to think that the hard part will be to turn this back into JS... Maybe something higher level than a generic loop node would be better after all.

(Technically truncating with “|0” after operations would make it safe. But that won’t appear in typical code, realistically.)

I was trying to see what it would take to optimize “a === a” to “true”. One idea was that if “a” is the result of basic arithmetic on integers (w/o division), it would be safe. But it’s not because multiplication/addition may eventually end in Infinity. And that times 0 is NaN.

TIL: Just by multiplying safe integers, you can reach NaN. Stupid floats.

The only thing that went away was the “node debug” variant, fortunately we were able to keep the general feature alive through that transition. :)

Things that allowed this to be a "single weekend project":

1. A great book by cliffclick (I'm roughly at chapter 5): github.com/SeaOfNodes/S...
2. The crates from oxc.rs for JS/TS. I could skip worrying about parser & scope analysis and jump directly into IR construction.

A control flow graph of a program that contains a phi node for merging data flow.

Achievement unlocked: Created my very first phi node. Wanted to learn more about both sea-of-node and Rust, so this was a great opportunity to check those off the list.

A follow-up meeting was just scheduled for “next year” (January) and I’m not sure how I feel about that.

YouTube video by We Love Speed How browsers REALLY load Web pages — Robin Marx

My talk from this year's We Love Speed is on YouTube! 👇

In "Tight Mode: how browsers REALLY load web pages", I take a very deep/very nerdy dive into why browsers sometimes intentionally delay loading resources, why they all do it differently, and why they should *stop clowning around* 🤡
