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.

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.

Kanban board in one HTML using localstorage
I figured I'd have a shot at making one of these: https://github.com/dreadnip/kanban
I don't need board/list management so I made simplified version with a fixed HTML structure, only the notes are dynamic. Also uses localStorage, browser drag & drop and single file without dependencies. Pretty fun exercise in building small single page applications with just JS. Thanks for the idea OP!
