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.

Ravi is a dialect of Lua, with JIT and AOT compilers
it's based off MIR, does it have something to do with https://mlir.llvm.org/ ?
for typed lua, there is another effort https://github.com/teal-language/tl in addition to the mentioned typescript approach: https://github.com/andremm/typedlua

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
- Why Fennel?

I wonder why the author doesn't use Teal [0] - a typed dialect of lua.

What's the deal with Fennel in Neovim?
There is already https://github.com/teal-language/tl, which is typed Lua. I think fennel exists to serve a different niche-- personally I use it not for any type features; I just like the syntax better, and others may find certain features like the macro system useful.

Using other languages
There's also some languages made to compile straight to Lua: - MoonScript is the most popular Lua wrapper - it's built to be more Python-like, featuring indentation-based scopes, function calls without parentheses, lambda syntax, list comprehension, and much more. - Yuescript is a modern update to MoonScript that adds more features (I haven't used it myself, so I'm not entirely sure exactly how it differs from MS). - Teal is a version of Lua that adds static typing for better code standards.

Bog – small, strongly typed, embeddable language
Terra and Nelua are both very different in goals than Teal. Teal is literally gradual types integrated into Lua keeping as many of Lua's idioms as possible (to a fault[1]). Terra and Nelua are both very metaprogrammable systems programming languages. Nelua's goals are primarily to soften C's rough edges, comparable to something like Nim.
There's another one you missed in Pallene[2]. But again, it's goal was to optimize the stack sharing involved in using the C API. It also adds types though and maintains Lua idioms as much as possible.

Mojo is now available on Mac
Chapel has at least several full-time developers at Cray/HPE and (I think) the US national labs, and has had some for almost two decades. That's much more than $100k.
Chapel is also just one of many other projects broadly interested in developing new programming languages for "high performance" programming. Out of that large field, Chapel is not especially related to the specific ideas or design goals of Mojo. Much more related are things like Codon (https://exaloop.io), and the metaprogramming models in Terra (https://terralang.org), Nim (https://nim-lang.org), and Zig (https://ziglang.org).
But Chapel is great! It has a lot of good ideas, especially for distributed-memory programming, which is its historical focus. It is more related to Legion (https://legion.stanford.edu, https://regent-lang.org), parallel & distributed Fortran, ZPL, etc.

Nelua, AOT statically typed Lua
Wow, amazing stuff. I love Lua, it was how I learned programming as a kid. Coincidently from the same world as the author. Open Tibia.
The author made a custom client (https://github.com/edubart/otclient) for the game that is still very much in active use by thousands of players. He's a very skilled developer.
Great to see AOT typed Lua, I know of the other solutions: Luau, Teal, TypeScriptToLua, Terra, etc., but this one is my favorite so far.
Love the simple compilation to C (and WASM support via Emscripten). Though Terra's JIT is enticing and good replacement for LuaJIT, this is for embedded systems, it's a good replacement for Lua PUC-Rio.

Idris: A Language for Type-Driven Development
Terra is a language that can also do that, and uses Lua as the metaprogramming language. Types are just Lua values.
But unfortunately, there's a lot of work left kind of half-baked so using the language is a pain... if someone invested a lot of time to make Terra work properly and added some tooling around it, wrote proper docs and so on, it would be a really interesting language.

Noob question about what's possible with comptime
(I am slightly familiar with a language called Terra (https://terralang.org), which couples C with Lua, where the Lua is basically used as the metaprogramming layer ... sort of like comptime in Zig. And making an SOA data structure is the kind of thing you could do in Lua in Terra. So that was partly the basis for my question).

Upcoming RISC-V laptop promises free silicon upgrades
> why can't the hardware designer do something simple and clean
If it was easy, it would not need firmware in the first place. Firmware is there because people expect certain features and quality of life. See softmodems.
> write some assembly (without abusing the assembler preprocessor...)
You want https://terralang.org/ and not "just C"/"just Assembler" instead ?
