"human ↔ machine collaboration" sounds rather creepy, to be honest.
keeganpoppen 10 hours ago|
tell that to Doug Englebart or J.C.R. Licklider-- the idea of human-computer symbiosis predates basically all computers that we would recognize as such today. crazy how it is only really now becoming true in the way that they envisaged in the 1960s.

what a lovely website
steveklabnik 11 hours ago||
Thank you!

We liked our old look, but one funny thing about how things are going in the world: our old color scheme was too close to what happens when you ask Claude to generate a site, and so even though we paid a human to build it, we didn't want to communicate slop, especially because that's not what we did!

Nick Noble is our designer, he put in a bunch of work on this, and I really like it too.

Nick is great! Met him at the Recurse Center. Brilliant designer.

I love how little latency there is on your website. I'm often thrown off by websites freezing on navigation, something we euphemistically call "loading". I feel we should have moved beyond that in the year of 2026. Your website really respects the user in this regard. Aesthetics are splendid as well.

It's killing my GPU tho so can't look at it took long without my fans going to max.
steveklabnik 10 hours ago||
What is your browser/OS combo? Thank you for bringing it up, we can only fix things that we hear about, so I appreciate knowing that something is off.
ModernMech 10 hours ago||
No worries, Windows 11, browser I just tested in Opera and Edge. Shared Intel GPU runs at 70% in either, guessing due to the lovely clouds drifting by.
steveklabnik 10 hours ago||
Thanks! I don't have Opera installed on my Win11 machine, but I tried it in Edge and it's barely using anything, but I realize that I have something beefier than a shared GPU on it.

I've filed a bug internally and we'll make sure to take a look. We don't use these animations in the product, only the company site, so this is the first time it's hitting a broader audience. I appreciate the report and sorry about that!

Firefox on win11 here, scrolling the page is super choppy and it pegs my GPU at 100%.

Thanks!

There will be a lot more of it soon :D

Hire somebody who's got at least a modicum of understanding of (web) typography.

Small hint: A moving background layer makes reading supremely annoying, and for some people even (virtually) impossible.

I'll have it stop on non-homepages, it should also respect reduce-motion.

Any other reccs?

I'm way more interested in knowing what technologies Steve Klabnik is eyeing and planning to get involved with next.

I joined ERSC ten months ago!

The things I am most interested in right now are jj and llms. And the intersection between the two. I'm thinking a lot these days about how agentic development is changing our industry, with source control being one part of that.

Congrats (or what's the right word :- )) Martin and best wishes to you and ERSC,

Looking forward to using the VCS stuff you'll create :- )

This website has unbearable scroll performance on mobile.

Is it the animation at the top?

steveklabnik 8 hours ago|
We tested it in mobile, but several people pointed out that we have more performance work to do to make sure that the animation is fast on lower-end hardware. I don't know what phone you're using, but we'll get it fixed regardless.

1 more data point - it's very slow on my desktop which has relatively high performance as well. Using Brave if that matters.
nickisnoble 7 hours ago||
We're about to push a change that should improve this a bit, thanks for the reports!

One more data point--I'm using Firefox on an M1 Mac mini (MacOS 15.7.7), and this web site destroys the responsiveness of this system in a way I have literally never seen before (4+ years) from anything, web site or otherwise.

I opened up Activity Monitor and CPU use looked normal but it showed the GPU was pegged at 100% as long as that page was open.

That’s amazing news. Can you share more about your tech stack? I suppose it’s mainly built with Rust?
steveklabnik 11 hours ago|
We have a colopholon! https://ersc.io/colophon

Rust is the default language for all of our non-frontend web stuff, yes.

Is this new? The date says July 8, 2026.
steveklabnik 11 hours ago|
Fixing, thank you!

(Martin joined back then, but we are posting about it today, so we should have the post date as today)

Can someone at ERSC please fix the issue preventing back/forward scroll gestures from working on the site?
nickisnoble 7 hours ago|
Filed a bug, looking into it!

Edit: a fix is in review
