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.

Relational is more than SQL
LINQ in EntityFramework (EF) supports querying JSON columns as objects [1].
unnest support is on the roadmap for EF core for PG [2], but already supported for Couchbase [3].

Table partitioning in Postgres from Migration
Sure. I readed https://event-driven.io/en/postgres_superpowers/ and i was curious about implementing partitioning in pg so i searched but i found there are not much results, except this open issue https://github.com/npgsql/efcore.pg/issues/1035. Also there is a pull request from April 2021 to handle this but it fail some tests https://github.com/npgsql/efcore.pg/pull/1789.

Poll results, repository pattern over Entity Framework?
Place I joined is using InMemoryProvider for tests. I tried upgrading to .net 6 and the .net 6 npgsql driver. Certain things bit us like no more support for EF.Functions.Like.

Auto Generate Sequential UIID
You basically want Hashids but sequential? Why not simple convert a base 10 (0-9) number to hex? (0-F)

Features I'd Like in PostgreSQL
I found hashids [1] to be a great compromise between integer ids in the database and copyable non-enumerable strings on the client.

We Chose NanoIDs for PlanetScale’s API
I wonder how this might compare to just storing regular autoincrementing ints in the database, and converting to/from hashids (https://hashids.org/) at the edge. It eliminates the collision concern and stores more compactly at the cost of a tiny amount of encode/decode when processing requests. You’d want to push it down as close to the database layer as possible to avoid inadvertent int ID leaks; I added native hashids support to clickhouse but I’m not sure what other database support might entail.
-
How can I generate truly unique slugs?
Since hashids are not really hashes and are not secure at all this is not even achieved. Hashids can be easily decoded without the salt by a simple brute-force attack described by the authors of hashid themselves right on their website: https://hashids.org/

How to handle id-based routes with UUID
You don't necessarily need to use UUIDs. You could use something like Hashids to generate random strings from your sequential IDs in a reversible way, so that users can't predict what their values will be, but you can decode them as needed.
-
All of my database models have id replaced with UUID4s. Is there any risk to using these in URLs?
You should not use UUIDv4 as a primary key. You can use normal int values and then use hashids to make them safe for URL. UUIDv7 might be good to use as well once they are more widely supported as well.
- What’s Django’s argument for using 64-bit int as default pk over uuid. Can anyone point me to something I can read?
