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.

Supabase Wrappers: A Framework for Building Postgres Foreign Data Wrappers
> speaks a particular API over the network
it's a interesting idea, and one of the things that we were toying with in our pg_net extension (https://github.com/supabase/pg_net). This is a "generic" async network extension, so you can fetch/put/post. It works well for APIs.
I think the generic approach works for some things where the data is less "fixed" - for example, an OpenAI API endpoint.
But for "fixed" data (data warehouses), the wrapper usually needs some custom work for security, protocols, and "push down". I'll be interested to get HN's take on this - they might have some suggestions for us for this framework

Show HN: Multiplayer Demo Built with Elixir
> finding the building blocks of modern applications (database, auth, functions, presence, realtime subscriptions), making them easy to use, and then sharing the source code.
Great observation!
> I’ve learned a ton just from cruising around supabase GitHub.
Glad to hear it!
> Can you say which of these new components will be open sourced?
All of these components are open source and licensed under Apache License v2.0.
> There are some other features (e.g. function hooks) that are also closed-source at the moment.
I actually worked on the initial implementation of function hooks. We've actually already open sourced both the client (see: https://github.com/supabase/supabase/tree/88bcef911669595428...) and the pg_net extension it requires (see: https://github.com/supabase/pg_net).
> Is Supabase heading for an “open core” model?
I don't think so. We want to continue to open source our projects under either MIT (client libs) and Apache License v2.0 (server libs).

Supabase Edge Functions
> The dream would be to have a great DX experience around using insert/update triggers to call Supabase functions to run background tasks
We have something for this: Function Hooks (soon to be renamed "Async Triggers")[0]. They are still in alpha, but the extension [1] is getting close. It was important to build something which works with PG background workers so that it's non-blocking. We'll make quick progress on this now that we've released Edge Functions.
> sending notifications or updating related rows
Tune in for tomorrow's announcement - it's related.

A Technical Dive into PostgreSQL's replication mechanisms
You can LISTEN/NOTIFY. Or you can use logical replication and a custom subscriber.[1] Supabase uses the latter.[2]

Supabase Studio: AI Assistant and User Impersonation
Supabase Realtime is great for building collaborative applications. You can receive database changes over websockets, store and synchronize data about user presence, and broadcast any data to clients via "channels".

Unpacking Elixir: Observability
We use :telemetry to collect usage data per tenant for Supabase Realtime.
We do this for rate limiting but it also makes it very easy for us to attach a listener (https://github.com/supabase/realtime/blob/main/lib/realtime/...) which ships these (per second) aggregates to BigQuery (via Logflare), which then the billing team can aggregate further to display and actually bill people with.

All the ways to capture changes in Postgres
Yo :D This is what Supabase Realtime does!
https://github.com/supabase/realtime
Spin up a Supabase database and then subscribe to changes with WebSockets.
You can play with it here once you have a db: https://realtime.supabase.com/inspector/new

Writing a chat application in Django 4.2 using async StreamingHttpResponse
Where can I learn more about this? I've been thinking of trying to integrate Supabase Realtime (https://github.com/supabase/realtime) into my Django app (without the rest of Supabase), but I'd also like to keep things even simpler if possible.
Also, what was the reason not to go with Gevent?

How To Kill A Fly With A Shotgun
As a minor note, one of the linked articles talks about having used RethinkDB for its changefeeds and I made a mental note a bit back that if I ever want that supabase's realtime ( https://github.com/supabase/realtime ) provides something rather like that atop Postgres and I should try that before doing anything clever.
