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.

Lua has been a real eye opener for this Java dev
If you Like Lua's syntax and you wish you could achieve C speeds and have the metaprogramming ability of Java (Generics), by all means try https://nelua.io/ , you won't regret it!
- Minimal, simple, efficient, statically typed, compiled, metaprogrammable, safe, and extensible systems programming language

Pixelhopper: Tiny animated GIF player in C, with seeking, pause, etc (Linux x11 only, for now)
I should be uploading the code sometime this week, by the way. I'm looking for a way to bundle the code (which is written in Nelua) in a single C file, so anyone can build it without having to install all of the language and the dependencies.

Is it possible to make an OS in Lua?
You could probably write a kernel in Nelua or Luau, though I don't know of any efforts to do so.

Nelua, AOT statically typed Lua
I already asked this question exactly 2 years ago: https://github.com/edubart/nelua-lang/discussions/51

Building a baseline JIT for Lua automatically
As far as I can tell, they aren't.
http://lua-users.org/wiki/SandBoxes
There is a lot of information there, but it doesn't handle resource exhaustion, execution time limits or give any guarantees. It does indicate that it's possible, and has a decent example of the most restrictive setup, which is a good start. But I would for example compare it with Luau's SECURITY.md.
From https://github.com/luau-lang/luau/blob/master/SECURITY.md:
> Luau provides a safe sandbox that scripts can not escape from, short of vulnerabilities in custom C functions exposed by the host. This includes the virtual machine and builtin libraries. Notably this currently does not include the work-in-progress native code generation facilities.
> Any source code can not result in memory safety errors or crashes during its compilation or execution. Violations of memory safety are considered vulnerabilities.
> Note that Luau does not provide termination guarantees - some code may exhaust CPU or RAM resources on the system during compilation or execution.
So, even luau will have trouble with untrusted code, but it specifies exactly what happens and so on. I think that's fair enough.

Pluto, a Modern Lua Dialect
Alternatively, Luau is a well-supported Lua variant with type checking and performance improvements, aimed more towards being a sandboxed embedded scripting environment.

Buzz: A lightweight statically typed scripting language
If you need Lua but also type-safety, how about Luau [1] then?

Lua Criticism Is Unwarranted
I had the pleasure of working with Lua 5.1 back in the late noughties. For me it's replaced Tcl whenever I want something I can configure above a C library. At the time I used it I found it quite nice but I'll also not forget the hours I wasted tracking down nil table corruptions which could have easily been caught by a type checker.
I had some hope that Luau https://luau-lang.org or Teal https://github.com/teal-language/tl would make things better but with the following example
function foo(x: number): string

Ask HN: Looking for platforms, other than Roblox, that have adopted Luau
Looking at other replies here, I can see I wasn't the only one who didn't realize there is Lua and Luau. Luau is an extension of Lua: https://luau-lang.org/
> Luau is syntactically backwards-compatible with Lua 5.1 (code that is valid Lua 5.1 is also valid Luau); however, we have extended the language with a set of syntactical features that make the language more familiar and ergonomic.

Embeddable Common Lisp 23.9.9
Lua is usually the embedded language of choice. If you are focused on security, you could check out the Roblox fork, Luau (https://github.com/Roblox/luau) where the creators took extra care to lock down the language on what scripts could do.

On a side note, I've heard that they recently switched from Lua to Roblox's own fork of Lua, Luau.
