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.

- Aper: a Rust library for data synchronization using state machines.

You might not need a CRDT (Conflict-free Replicated Data Type)
The relevance here is that this post mentions their new Rust library Aper (https://aper.dev/). In addition, CRDTs are a favorite topic of Raph Levien, AKA the Rust GUI guy, and featured in the Xi editor, his first major Rust project (retrospective here: https://raphlinus.github.io/xi/2020/06/27/xi-retrospective.html).

You might not need a CRDT
It's also super refreshing to see the work on Aper [1] [2] (a Rust library implementing state machine synchronization across a trusted network). Looking forward next series of articles here!

CRDTs make multiplayer text editing part of Zed's DNA
Our Aper (https://aper.dev) implements a number of similar concepts (state machine replication with optimistic local transitions + rollback). I 100% agree that itβs an easier model to reason about.
Your approach with cursors is clever, that part I havenβt seen elsewhere.

Ask HN: Who is hiring? (June 2022)
Drifting in Space | Full-time | NYC | https://driftingin.space
We make Jamsocket (https://jamsocket.com/), which allows application developers to spin up and connect to server-side compute. This allows browser-based applications to do computationally-intensive things that are otherwise impossible in the browser.
We went through YC and just raised a seed round and are looking to build up our team. We are based in NYC but are open to remote for experience candidates.
Our tech stack includes Rust, NATS, Docker, Postgres, TypeScript.
We have lots of fun technical problems that get into the nitty-gritty of networking and operating systems, plus fun open-source stuff like Aper (https://aper.dev/). We are excited to build a diverse team and encourage non-traditional candidates to apply.

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.

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.

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.

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.
