What a pivot, from manga to software

Working with Martin has been a real pleasure, and we'll have some more stuff to talk about very soon!

what a lovely website

Jujutsu is apparently the name of a version control system, for anyone else confused how the creator of a thousand year old martial art had joined them.

What is ERSC?

Someone will have to explain the value proposition to me... We have git. jujutsu works with git. git can do everything jujutsu can do (otherwise, jujutsu couldn't work with git). Thus, jujutsu is a UX / new steering wheel. ERSC is trying to be a GitHub competitor with what surplus value? Don't get me wrong, GitHub has a slew of its own problems, but I have not seen any commentary on how ERSC addresses any of the downfalls GitHub has too. We're jumping from one frying pan into another, currently-cooler one? What about SourceHut? Codeberg? They could offer the same steering wheels. Edit: Thank you to everyone who replied. The enterprise/teams infrastructure angle makes sense.

Jujutsu is a better smarter git. It's a great convergence of better UX, plus more expressive, plus easier to use. If you haven't tried jj yet, take it for a spin and see how you like it.

This looks like excellent news.

That’s amazing news. Can you share more about your tech stack? I suppose it’s mainly built with Rust?

ksymph

So if I understand correctly: ERSC is working on an alternative backend for jj other than git (and presumably providing related infrastructure)?

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 :- )

(off topic) why the headache-inducing animated background? An annoyance for all, and an actual accessibility issue for some.

jj is one of the few new devtools I was quite frustrated with while starting out but could see the value so stuck around and man is it so nice. For anyone curious the big thing with jj is you can undo. Basically if you were running a rebase and bungled a commit sha or branch name, no worries undo your way out, if you forgot to push but abandoned a commit not issues undo it. Same with all jj commands. Delta db takes this a step further and everything you edit is a change so your actual edits are also all saved. I find non destructive-ness for as long as possible approach very nice, since there aren't as many constraints on us not being able to do it nowadays, we had limited storage and stuff in 2000s perhaps but in 2026 even with the killer SSD prices it's fairly cheap to buy more SSD, we can definitely waste 100MB per project storing redundant history we may not ever need. Same way in photoshop non destructive editing took over, especially useful for humans, but works for AI and LLMs too, they can undo their mistakes as well.

No word about the future of Jujutsu, so I guess this is bad news for for jj users?

"human ↔ machine collaboration" sounds rather creepy, to be honest.

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

This website has unbearable scroll performance on mobile. Is it the animation at the top?

Degorath

Thought I saw that announcement on LinkedIn a few weeks back already!

mplewis

Can someone at ERSC please fix the issue preventing back/forward scroll gestures from working on the site?
