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.

Realtime: Multiplayer Edition
Wen Bo from the Supabase Realtime team here!
We actually use https://github.com/supabase/walrus to get the database changes and we're planning on moving to a Rust worker (https://github.com/supabase/walrus/tree/worker/worker) for better performance especially in the RLS-enabled use case.
I promised José that I would check out Postgrex.ReplicationConnection and we might add it in to our Supabase Realtime some time in the future.

PostgreSQL 14 Released
[Supabase cofounder] thanks for the kind words.
We're about to wrap up Row Level Security on our real-time APIs too[0] - soon you'll be able to use Policies universally on all APIs.

Supabase limitations ? Any reasons not to use?
We are adding this to the database now: https://github.com/supabase/walrus

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.

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.

- How does Google docs send the changes done by other users in real-time?
What are some alternatives?
symmetric-ds - SymmetricDS is database replication and file synchronization software that is platform independent, web enabled, and database agnostic. It is designed to make bi-directional data replication fast, easy, and resilient. It scales to a large number of nodes and works in near real-time across WAN and LAN networks.
automerge - A JSON-like data structure (a CRDT) that can be modified concurrently by different users, and merged again automatically.
pgvector - Open-source vector similarity search for Postgres
liveblocks - Liveblocks is a platform to ship collaborative features like comments, notifications, text editors in minutes instead of months.
wal2json - JSON output plugin for changeset extraction
automerge-rs - Rust implementation of automerge [Moved to: https://github.com/automerge/automerge]
