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.

What’s everyone working on this week (1/2023)?
(next I would like to create a Reddit read-oriented app with the same phylosophy, probably in Druid this time; but I still need to finish my Sim City 1 rewrite in Rust/WebAssembly/React among a couple of other long-running projects...)

Out of the loop: WASM for non-web projects
I was/am working on a project (https://github.com/JMS55/botnet), where users upload scripts compiled to WASM to control entities on a game server, so that they can write custom behavior.

Sandboxing DLL Code
Never heard of extism before, but second using WASM for plugins/scripting/extensions. I'm using it for botnet(1). Each player uploads a WASM program to control their bots. Both the server and the bot SDK are written in Rust, and can share some code.

Why Am I Excited About WebAssembly?
4. Speed
I'm hoping to write my thesis for my master's degree on this topic this year. I'm also in the process of writing a game like screeps, where users provide a WASM script to control units for an RTS-style game (without combat though) https://github.com/JMS55/botnet.
It's amazing how simple it is to constrain memory usage, runtime duration, and secure exported functions to a WASM VM. Performance is also great - currently about ~6 microseconds per tick per unit, up to ~200 microseconds when doing expensive pathfinding. All that, while letting you program your units in Rust - the same language as the server is written in, while being able to share code with the server, and not having to use something more script-y like lua.

easy to use Plugin API in rust?
The boilerplate sucks, but it works well when you don't need a ton of different functions. I use wasm as a scripting language for running isolated untrusted scripts in a game I'm developing, and it works really well https://github.com/JMS55/botnet.

Ask HN: Who needs help with side projects?
I'm working on a Screeps-like game using WebAssembly. You compile a script to WebAssembly, and for each robot you control on the server, it runs the script in an isolated environment to choose an action for that robot. The goal is to write a program to coordinate your robots to gather resources and expand your control of the server.
Here's an example bot script: https://github.com/JMS55/botnet/blob/master/example_bot/src/...
The basic infrastructure of the project is more or less in place, besides a visual replay viewer which I'm working on right now. What's needed is a bunch of work in designing game mechanics and APIs. I don't actually have any plans beyond bots running around and harvesting randomly generated resources at the moment. Feel free to open a discussion on the github page if you're interested in Rust, WebAssembly, and video games.
