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

Supabase Local Dev: migrations, branching, and observability
Every project is a Postgres database, wrapped in a suite of tools like Auth, Storage, Edge Functions, Realtime and Vectors, and encompassed by API middleware and logs.

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 Listen to Database Changes Using Postgres Triggers in Elixir
I believe #2 was the main driver for the supabase team to build their real-time component: https://github.com/supabase/realtime

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.

LibreScan, the First Decentralized Blockchain Explorer Supported by QANplatform – Press release Bitcoin News
If decentralized means, "run their own blockchain explorer on a PC and always have secure access to their explorer without being tracked", then that includes iquidus explorer, and blockscout, and those were just quickly found with google. Both of those projects have working code and support multiple altcoins (not affiliated). "First" is a wildly incorrect claim.

Oasis Network November Engineering Update
We are developing a custom version of the BlockScout block explorer which will serve as the Emerald block explorer. It will launch by the end of December.

Using blockscout for explorer
Any reason why we don't use https://github.com/blockscout/blockscout for the explorer instead of building our own? To me it looks like blockscout already has lots of feature that are missing in the current explorer.

How to see all NFT’s minted to a specific address? I expected to be able to see this on blockscout but maybe I’m looking in the wrong spot? I was hoping for a one stop shop to see NFTs of any type for a given address instead of having an app on my phone dedicated for different types.
Blockscout is the right solution. However, there is a bug and an open issue: https://github.com/blockscout/blockscout/issues/4203

How to verify Quickswap Rewards Contract && Devs please tell us what optimization you used!
blockscout team suggests the polygon upgrade to pull/3715 and that might solve the issue. I've added to my open ticket with matic support. I can also see an open ticket surround code verification for Aave linked to the same update in blockscout's github: https://github.com/blockscout/blockscout/issues/3752
