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.

Extracting Timestamp From CUID (Snowflake ❄️)
Not sure if this is the same, but a cuid related project had this requested a feature https://github.com/paralleldrive/cuid/issues/63

The best UUID type for a database Primary Key
I like this ones https://github.com/paralleldrive/cuid

UUID/GUID, CUID & NanoID: What's The Difference?
CUID aims to solve the exact problem we discussed above with UUIDs. Quoted from CUID's GitHub:
- ROUBARAM UMA AARTE MINHA PRA FAZER NFT DE MAMACO! ÓDIO E NOJO DE CRYPTO!
- PostgreSQL UUID vs. Serial vs. Identity
- Collision-resistant ids optimized for horizontal scaling and performance

Next.js and Bunny CDN: Complete Guide to Image Uploading with Server Actions
Last thing left is to use our new upload function in our server action. Since I like to upload images in single format and have some more control over them, I will additionally use sharp library. For file name, I'll generate some random string using nanoid:
- Nano ID Collision Calculator

Why we chose Bun
Our API is in node. And God, how I suffered to import nanoid in an esmodule project. I had to vendor it, since using a previous version was not ideal. With bun, we can no longer worry about that. Just import what you need and done.

UUIDv7 is coming in PostgreSQL 17
No thread about UUID is complete without a plug for NanoID! https://github.com/ai/nanoid/blob/main/README.md

Building a File Storage With Next.js, PostgreSQL, and Minio S3
Generate a unique file name using the nanoid library.
-
Building a Multi-Tenant App with FastAPI, SQLModel, and PropelAuth
The syntax should read similar to SQL itself. We’re using a Python port of nanoid to generate our IDs. There’s only one thing missing… how do we actually create the table?

You Don't Need UUID
I usually go for Nano Id for new projects https://github.com/ai/nanoid

Analyzing New Unique Identifier Formats (UUIDv6, UUIDv7, and UUIDv8) (2022)
In another comment I mentioned I use nanoid in my projects now. It has a default space of 64^21 and has an a page where you can play with key lengths and alphabet sizes and see the probability of collisions :
https://zelark.github.io/nano-id-cc/
At the default 64 character alphabet with a 21 character key length it would take ~41 million years in order to have a 1% probability of at least one collision if you generated 1000 ids per second.

How I use Nano ID in Rails
Using randomly generated IDs like Nano ID could be a good alternative, however, as a developer, we must understand what Nano ID really does in our application. Defining the number of characters in the generated IDs is also important, to help with that Nano ID has a Collision Calculator to give us how many years in order to have a 1% probability of collision.
