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.

Garbage Collection for Systems Programmers
I'm one of the authors of this work -- I can explain a little.
"Provably efficient" means that the language provides worst-case performance guarantees.
For example in the "Automatic Parallelism Management" paper (https://dl.acm.org/doi/10.1145/3632880), we develop a compiler and run-time system that can execute extremely fine-grained parallel code without losing performance. (Concretely, imagine tiny tasks of around only 10-100 instructions each.)
The key idea is to make sure that any task which is *too tiny* is executed sequentially instead of in parallel. To make this happen, we use a scheduler that runs in the background during execution. It is the scheduler's job to decide on-the-fly which tasks should be sequentialized and which tasks should be "promoted" into actual threads that can run in parallel. Intuitively, each promotion incurs a cost, but also exposes parallelism.
In the paper, we present our scheduler and prove a worst-case performance bound. We specifically show that the total overhead of promotion will be at most a small constant factor (e.g., 1% overhead), and also that the theoretical amount of parallelism is unaffected, asymptotically.
All of this is implemented in MaPLe (https://github.com/mpllang/mpl) and you can go play with it now!

Zig, Rust, and Other Languages
There's also Odin[0] too. I tried using them all and Odin was pretty nice. Nim is also good too but a lot more features.
But - I concluded that language matters a lot less compared to APIs. Yes, the language should have enough good features to let the programmers express themselves, but overall well designed APIs matter a lot more than language. For example -tossing most of the C stdlib and following a consistent coding style (similar to one described here -[1]), with using Arenas for memory allocation, I can be just as productive in C.

Odin Programming Language
I highly recommend looking at:
* The Overview: <https://odin-lang.org/docs/overview/>
* examples/demo: <https://github.com/odin-lang/Odin/blob/master/examples/demo/...>
As for the first example: a basic lexing example is probably boring, but it does show some basic ideas of what the language is about. If people want to write better examples or just reorder the current ones, please feel free to make an issue or PR on the website's GitHub page: <https://github.com/odin-lang/odin-lang.org>.

Download Odin and get started today! Includes binding to popular video game libraries
Get it from the website: https://odin-lang.org/ -- Odin includes bindings to popular gamedev libraries & APIs such as Raylib, SDL, DirectX, OpenGL and Vulkan.
- Check this odin file out for a demo of many of the language's features. It comes with the compiler inside the examples folder. I refer to it all the time when I need to figure out how to do something.
