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.

Shiftnanigans - 2D Platformer Randomizer
I made a 2D platformer randomization crate called Shiftnanigans (https://github.com/AustinHellerRepo/Shiftnanigans) as part of my work on the open source game Jumpy (https://github.com/fishfolk/jumpy). Within the map editor of Jumpy, the Randomize button will randomize the placement of tiles and elements, maintaining the general structures of the map. I've described the two abstract concepts and sets of structs used to accomplish this functionality below. This is just a general overview, but I am happy to elaborate further if anyone has questions about the algorithms and data structures used.

Fish Folk: Jumpy v0.5 – completed MVP of Bevy rewrite
Since late September we've been rewriting 'Fish Folk: Jumpy' in Bevy, headed up by Jumpy's new lead dev zicklag. With the release of v0.5, we now set our sights on a crowdfunding campaign due to launch in early 2023.
- Networking in ‘Fish Folk: Jumpy’ with QUIC for matchmaking and GGPO for p2p rollback

Wave Function Collapse - A stateful node graph framework (constraint problems, procedural generation, etc.)
Thanks for this! We have a longstanding idea to use WFC as a way to create procedurally (re-)generated maps for our 2D platformer game. Happy to collaborate further on this if you’re interested.

Katharos tech?!
Also the people from Katharos are great contributors of Bevy itself and also is working on Jumpy, which is a great source of inspiration and showcase for community, which doesn't uses Katharos License.

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.

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

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.
