Our great sponsors
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Making CRDTs 98% More Efficient
One idea is just to use fewer random bits in peerIDs. Yjs (https://docs.yjs.dev/) gets away with just 32 random bits. If you compromise and use 64 random bits, then even a very popular doc with 1 million lifetime peerIDs will have a < 10^-7 lifetime probability of collision.

An Interactive Intro to CRDTs
I've seen it come up often in collaborative text editors.

JSON Schema Store
You are absolutely right that XML is better for document structures.
My current theory is that Yjs [0] is the new JSON+XML. It gives you both JSON and XML types in one nested structure, all with conflict free merging via incremental updates.
Also, you note the issue with XML and overlapping inline markup. Yjs has an answer for that with its text type, you can apply attributes (for styling or anything else) via arbatary ranges. They can overlap.
Obviously I'm being a little hypabolic suggesting it will replace JSON, the beauty of JSON is is simplicity, but for many systems building on Yjs or similar CRDT based serialisation systems is the future.

Launch HN: Tiptap (YC S23) – Toolkit for developing collaborative editors
Note: https://github.com/yjs/yjs for collaborative "document edition, and user cursors"; has WebRTC, web socket, matrix.org backend

Wormholers, what can CCP and wormholers do to improve J-Space?
CCP needs to revamp proto anyway, due to recent exploits... practically, nothing really prevents 'em from using some sort of CRDT's to make the state of the sig view eventually consistent (yjs lib, if we're speaking frontendian).

How to use Yjs with Ruby on Rails?
Yjs framework: Because it is a CRDT implementation which provides collaborative editing and offline-first capability.

🐑🐑🐑 EweserDB, the user-owned database 🐑🐑🐑
No problem. The database CRUD features are just helpers as an abstraction on top of yjs: https://docs.yjs.dev/. Eweser adds schemas in the form of typescript types to make using it simpler, more structured, and interoperability easier.

Question About Runtime Mesh Editing
You can find a few algorithms online (such as csg.js and libfive), but most of them are either not robust or fast enough for real-time graphics.

Show HN: Make 3D art in your browser using Lisp and math
No; Bauble doesn't know how to "rasterize" SDFs into meshes; it only knows how to raymarch them. It's theoretically possible, but it's a pretty complex problem that would take me much too long to figure out and implement. So Bauble is relegated to just making pretty pictures for now.

Antimony – computer-aided design tool from the Lisp machine parallel universe
This is a mid-point in Matt Keeter's research.
Start at:
http://mattkeeter.com/research/thesis.pdf
then see:
http://www.mattkeeter.com/projects/kokopelli/
then Antimony (see the article at: http://hackaday.com/2015/05/29/otherworldy-cad-software-hail... ), then the current effort:
https://github.com/libfive/libfive
(and also see: https://www.gitlab.com/kavalogic-inc/tovero "a binding of Libfive to Common Lisp, including a standalone REPL-based viewer"[https://github.com/Irev-Dev/curated-code-cad] can be integrated with https://www.gitlab.com/kavalogic-inc/clive
Currently I'm using OpenSCAD (w/ BlockSCAD as a front-end: https://www.blockscad3d.com because I prefer a sort of visual representation), but have been stymied by the lack of file I/O (I want to write out G-code).
Still looking for a 3D modeling tool which is:
- a node or block editor
- Learning CAD on Linux
- OpenSCAD 3D rendering just got an order of magnitude faster
- CadQuery –- A Python parametric CAD scripting framework based on OCCT
What are some alternatives?
automerge - A JSON-like data structure (a CRDT) that can be modified concurrently by different users, and merged again automatically.
jupyter-cadquery - An extension to render cadquery objects in JupyterLab via pythreejs
liveblocks - Liveblocks is a platform to ship collaborative features like comments, notifications, text editors in minutes instead of months.
curv - a language for making art using mathematics
automerge-rs - Rust implementation of automerge [Moved to: https://github.com/automerge/automerge]
