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.

Beginner looking for code review : my ECS lib !
For further reading, here is a great article about these different approaches within Rust specifically: https://csherratt.github.io/blog/posts/specs-and-legion/ and here is a great general resource for commonly-used terms and techniques in ECS development: https://github.com/SanderMertens/ecs-faq

Ways to create game engines
Godot has a node based system (nodes can have child nodes linked to them, and there are different types of nodes for the type of functionality they represent). Another alternative could be a more OOP approach (utilising inheritance as the main means of extending functionality), not aware of any modern engines that take this approach anymore. Itโs also worth noting that ECS implementations can differ wildly, this faq from the flecs creator has a good rundown on what some of different variants are.

Is ECS really the way to go in C++?
You might wanna take a look at https://github.com/SanderMertens/ecs-faq, it lays this all out better than I can.

Functional relational programming model in Clojure(Script)
Using the relational model for app data in memory is really interesting.
Martin Fowler wrote about doing that as a way to get around the "object-relational mismatch" issue[1]. Richard Fabian describes "data-oriented design" as having a lot of overlap with the relational model[2]. ECSes becoming very popular in game engines are basically in-memory relational databases where "components" are "tables"[3].

does an ECS system need unique identifier ( uuid ) ?
This is the ECS FAQ I'm currently using.

What are some things you have used ECS for?
While Unity's DOTS/ECS is positioned as solving performance issues for large numbers of objects, there are a number of other advantages. See https://github.com/SanderMertens/ecs-faq for a more in-depth look. IMHO the reusability and extensibility ECS encourages is as valuable as any performance increase. Compared to the GameObject style, which encourages random state mutations and side-effects, ECS enforces a more functional style, which results in code that is easier to reason about and test.

Dominion VS Artemis, the missing benchmarks (link in the comments)
thanks, i think a little more background on the ECS world will help you get the context, this is from the author of Flecs: https://github.com/SanderMertens/ecs-faq

Create a Custom GitHub Action in Rust
Rust has a rich ecosystem of frameworks and libraries that let you read, parse, and manipulate text files, interact with cloud services and databases, and perform any other job that your project's development workflow may require. And because of its strong typing and tight memory management, you are much less likely to write programs that behave unexpectedly in production.

Migrating a JavaScript frontend to Leptos, a Rust framework
So, be sure to double-check your critical libraries and be sure their alternatives exist in the Rust ecosystem. Thereโs a good chance the crates you need are available in Rust's crates.io repository.

Learning Rust: A clean start
The previous section was very simple, this section is also very simple but introduces us to cargo which is Rust's package manager, as a JS dev my mind goes straight to NPM.

#2 Rust - Cargo Package Manager
Now, there has to be a place where all these packages come from. Similar to npmjs registry, where all node packages are registered, stored and retrieved, Rust also has something called crates.io where many helpful packages and dependencies are registered.

The most thrilling aspect has been the joy of writing the backend. It's like every struct, enum, and method in Rust forms this interconnected Multiverse of code , which you can see in crates.io which is best Documentation experience I Ever Had.

Cargo has never frustrated me like npm or pip has. Does Cargo ever get frustrating? Does anyone ever find themselves in dependency hell?
Vendoring your packages was very tedious to even remotely get to work with Cargo. I spent a very long time getting Cargo to work together with cargo-local-registry. We vendor crates from crates.io and a custom internal registry.
