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.

On the impossibility of composing finalizers and FFI
Unfortunately things aren't so simple, as when doing JIT compilation, LuaJIT _will_ try to shorten the lifetimes of local variables. Using the latest available version of LuaJIT (https://github.com/LuaJIT/LuaJIT/commit/0d313b243194a0b8d239...), the following reliably fails for me:
local ffi = require"ffi" -
Building a baseline JIT for Lua automatically
I am using https://luajit.org/ in my GCC C++ project.
Can I use this faster Lua JIT in my project as a replacement? And if so, how so?
The existing luajit doesn't do v5.1, so it would be nice to use this newer engine at the newer baseline lua version level.

LuaJIT Uses Rolling Releases
I think https://github.com/LuaJIT/LuaJIT/commit/6a2163a6b45d6d251599... improved things a bit, notably making automatic tarballs work again.

How to clear a table without wasting memory?
There is nothing on luajit.org, so I assume that 2.0 doesn't have the extensions added (think the site is still on 2.0). However I found some proof in the mirrored git repo, that they do exist and also my luajit interpreter (2.1.0-beta3) shows them as builtins.

Recommendations for JS Engines that could be embedded in my Game Engine
If you absolutely want a performant scripting runtime, I'd recommend taking a look at LuaJit, DaScript or AngelScript.

Any embeddable language compatible with C (like Lua) but compiled?
If you don't like that - look towards JIT-compilers. Lua has one

Show HN: I wrote a WebAssembly Interpreter and Toolkit in C
> I developed a unique way to write interpreters based on threaded code jumps and basic block versioning when I made MiniVM (https://github.com/FastVM/minivm). It was both larger and more dynamic than WebAssembly.
I'd be very interested to read more about this. It looks like you are using "one big function" with computed goto (https://github.com/FastVM/Web49/blob/main/src/interp/interp....). My experience working on this problem led me to the same conclusion as Mike Pall, which is that compilers do not do well with this pattern (particularly when it comes to register allocation): http://lua-users.org/lists/lua-l/2011-02/msg00742.html
I'm curious how you worked around the problem of poor register allocation in the compiler. I've come to the conclusion that tail calls are the best solution to this problem: https://blog.reverberate.org/2021/04/21/musttail-efficient-i...

Ask HN: Recommendation for general purpose JIT compiler
Maybe take a look at MiniVM[0]? It was on HN a couple months ago[1].
