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.

CRDT-richtext: Rust implementation of Peritext and Fugue
https://github.com/samsquire/multiversion-concurrency-contro...
And I implemented a 3 way text diff with myers algorithm based on https://blog.jcoglan.com/2017/02/12/the-myers-diff-algorithm...
https://github.com/samsquire/text-diff
I implemented an eventually consistent mesh protocol that uses timestamps to provide last write wins

Visualizing Diffs The Myers difference algorithm
I implemented a three direction diff at https://github.com/samsquire/text-diff
Conflict detection is fairly hard to get right, I can detect overlapping ranges to colour the output green or red.

Ask HN: How Can I Make My Front End React to Database Changes in Real-Time?
I'm interested in this problem also!
I think there is a large overlap with projects that market/focus on offline-first experiences.
AFAIK this problem can be solved by:
1) Considering a client-side copy of the database that gets synced with the remote DB. This is an approach [PowerSync](https://www.powersync.com/) and [ElectricSql](https://electric-sql.com/) and [rxdb](https://rxdb.info/) take!

Cloudflare acquires PartyKit to allow developers to build real-time multi-user
Yeah I agree with it being an exaggeration. They are certainly riding the admittedly dated perception that realtime is so hard it's only available to the Googles and Figmas. But there's now some amazing open source solutions available like Y.js and ElectricSQL[1]. The barrier has certainly come down.

PostgreSQL 16 Bi-Directional Logical Replication
https://github.com/electric-sql/electric :
> ElectricSQL is a local-first software platform that makes it easy to develop high-quality, modern apps with instant reactivity, realtime multi-user collaboration and conflict-free offline support.
> Local-first is a new development paradigm where your app code talks directly to an embedded local database and data syncs in the background via active-active database replication. Because the app code talks directly to a local database, apps feel instant. Because data syncs in the background via active-active replication it naturally supports multi-user collaboration and conflict-free offline

Show HN: PowerSync – Bi-directional Postgres<>SQLite sync for offline-first apps
Yup, this is correct.
We have had some requests / discussions around adding hooks to the sync service that will support custom logic on the write path (as per https://github.com/electric-sql/electric/discussions/565). This seems like a good idea but they don't exist yet.
