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.

[DDD] Tactical Design Patterns Part 3: Presentation/Infrastructure Layer
It has been decided to use uuid Version 4 for all of them. Noteworthy is the CommentId, which serves as the identifier for entities within the boundary, meaning local identifiers. For this case, there is no necessity to use uuid. Evans used positions such as front-left, rear-left, front- right, and rear-right to identify the wheels of a car. However, unlike wheels, no straightforward, real-world, understandable means of identification for CommentId came to my mind, so the uuid framework was adopted as a convenient and easy generation method.

Exploring the Most Commonly Used Folder Names in Popular NPM Packages
.husky: Git hooks are custom scripts that run in response to some event (e.g. before a commit is created), and they can choose to abort that event under certain conditions. One of their main drawbacks though is that they live inside the .git folder, which means they cannot be directly versioned like the rest of the project. This folder is used by the popular Husky package that makes it possible to include Git hooks with your project and it takes care of installing them to their appropriate location so they can be detected by Git. Example from uuid.

How I designed an abuse-resistant, fault-tolerant, zero cost, multiplayer online game
activePlayers is a map of unique player IDs (determined by clients via uuid to timestamps of when they last made a GET https://farmhand.vercel.app/api/get-market-data?room=global request. Each time the function is invoked, it examines the map to see which timestamps are older than the HEARTBEAT_INTERVAL_PERIOD (currently 10 seconds) and deletes any that are expired. This data is returned to the client and also written back to Redis to be persisted across function invocations. This is how the active room participants are tracked.

Precaching pages with next-pwa
By default Next.js uses nanoid to produce build ids so I used that too. You don't have to use it, there are other options, such as uuid.

How to Build a Javascript Chat App
You need to include some third-party libraries such as CometChat Widget, Uuid, Validator, Firebase via CDN because you are building the Javascript chat app. Therefore, npm should not be used here. You need to add those libraries for some reasons:

Introduction to typescript with React
Let's get back to the uuid package. uuid package is not written in typescript. However, there is a @types/uuid package for it. The package is installed using npm install --save-dev @types/uuid. This way when we assign an uuid to a todo's id, typescript knows, we are assigning a string to id.

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.
I’ve started using nanoid for generated ids. Here is the JavaScript version:
Some info from that page:
- Safe. It uses hardware random generator. Can be used in clusters.
- Short IDs. It uses a larger alphabet than UUID (A-Za-z0-9_-). So ID size was reduced from 36 to 21 symbols.
- Portable. Nano ID was ported to 20 programming languages.

How I use Nano ID in Rails
Introducing Nano ID. Nano ID is a tiny, URL-friendly, and unique string ID generator. Nano ID is a library for generating random IDs that still have probability of duplicate IDs. However, this probability is extremely small and it is based on the rules you defined. Here are the features of Nano ID:
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.

Exploring the Most Commonly Used Folder Names in Popular NPM Packages
bin: Sometimes it may be desired or even crucial for a package to provide a command line interface, take a testing framework like jest as an example. NPM allows packages to publish executable binaries for this purpose, and as a convention they're usually placed in this directory. Example from nanoid.

Launch HN: Activepieces (YC S22) – Open-Source Zapier Alternative
The development began two months ago and we have not encountered any scaling issues yet, as the majority of users self-host. Therefore, our priority was focused on building apps. Is there anything you believe we should consider?
You are correct, repeating the same index twice is a mistake. That's why I love open source.
We are using nano id (https://www.npmjs.com/package/nanoid) for all entities, It's stored as varchar in the database.
What are some alternatives?
snowflake - Snowflake is a network service for generating unique ID numbers at high scale with some simple guarantees.
