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.

How do I use/install packages in CQ-Editor?
I have a need to use the thread module from https://github.com/gumyr/cq_warehouse, and I'm sure I'll use https://github.com/meadiode/cq_gears as well. I just downloaded CadQuery 2 for Windows, and I can't figure out where I need to download these repos so I can call them in the script.

Morphing crossed helical gears
My generator is here: https://github.com/meadiode/cq_gears It's built on top of 3d-CAD modelling library called CadQuery and as I mentioned earlier it's not specifically intended to be used with Blender, more like for general CAD needs.

CadQuery β- A Python parametric CAD scripting framework based on OCCT
One thing that kept me using OpenSCAD was the section of additional modules for it, including a decent involute gear creator. For those of you diving into CadQuery, hereβs the equivalent: https://github.com/meadiode/cq_gears

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) β 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

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

πππ EweserDB, the user-owned database πππ
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.

Show HN: Nostr-CRDT β real-time collaborative apps over Nostr
Hi HN!
Nostr-CRDT is an experimental project that connects Yjs [1] (a proven, high performance CRDT) with Nostr [2].
I wanted to learn about the Nostr protocol and see if it'd be possible to send updates to state (e.g.: edits of a rich text document, updates to a todo list) over Nostr.
Nostr describes itself as "The simplest open protocol that is able to create a censorship-resistant global "social" network once and for all.".
I like the idea of a decentralized social network, but what if we can decentralize more kinds of apps and create decentralized, local-first collaborative applications? I've been exploring this area for a while and earlier shared a Show HN post that does this over Matrix [3].
There's still lots to figure out, but imo it's a very exciting and rapidly developing space - looking fwd to your thoughts already!

Hindsight is a free and open-source retrospective board
No back-end. Data is shared via WebRTC directly between connected browsers. I'm using Yjs to help me with that.
