good point

Hey thanks! I made this, its very WIP so surprised anyone found it.
It's basically a 3d scene implemented in webgpu with a custom pixel shader. Server sided physics, streamed to the frontend with a very cheap client that just lerps stuff around in the scene.

I just posted this somewhere else -- but overall big fan of these text to cad rigs as projects.
Obligatory mention of https://zoo.dev/ who went to extreme lengths on this.
I will say I explored this reasonably deeply and came away with the conclusion that even though we have OpenSCAD and all these examples, LLMs are still very weak at spatial reasoning compared to diffusion models.
You can do all sorts of tricks like have a parts library to get around this and do physics checks but another inconvenient truth is whenever you design a complex assembly, every change to that part needs to be aware of the other parts in the design -- thus you need a global part-aware editing capability from diffusion.
That's getting solved already in china leading labs, and bottlenecked by the lack of good training data, which china is solving with mass labor.
This will be solved overseas first before we will in the US.
p.s. I am not affiliated with zoo or any of these other things FYI was just very curious about this whole area

Git AI is awesome -- very needed.

One would imagine they are broadly similar; but that's off the assumption that codebases are similar as well.
Migrations between versions can have big variance largely as a function of the parent codebase and not the dependency change. A simple example of this would be a supported node version bump. It's common to lose support for older node runtimes with new dependency versions, but migrating the parent codebase may require large custom efforts like changing module systems.

I run a sw supply chain company (fossa.com) -- agree that there's a lot of low hanging gains like inventory still around. There is a shocking amount of very basic but invisible surface area that leads to downstream attack vectors.
From a company's PoV -- I think you'd have to just assume all 3rd party code is popped and install some kind of control step given that assumption. I like the idea of reviewing all 3rd party code as if its your own which is now possible with some scalable code review tools.

Is it just me or is the upgrade path not turned on yet?

Very interesting research -- possibilities are endless for personalization, rigging, character animation. Especially interesting how few frames it takes to accomplish this.

This is a great take on Meta -- in some ways there's an element of macro justice or a return to form in tech and innovation with this shift.
There’s a merch shop and buyable coins but please don’t buy or redeem anything because that’s currently fake for the tech demo. The economy is also generous so no need to buy tokens — just wanted to show off the project!
