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.

WASM instead of C Dependencies?
Testsetup: Encode a 6048x2048px big image using mozjpeg (mozjpeg-sys to be more specific), resize it down to 1008x665px using PistonDevelopers/resize, and decode it again using mozjpeg.

Wazero: The zero dependency WebAssembly runtime
https://github.com/tetratelabs/wazero/releases/tag/v1.7.0
This includes the final release of the new optimizing compiler, which is a big improvement over the previous one.
The new version also adds experimental support for threads and snapshot/restore (setjmp/longjmp).
This is already being used by go-pgquery, all will mean that sqlc won't need to ship to almost copies of wazero (these features had been implemented on a friendly fork, and have now been up-streamed).

Making Games in Go for Absolute Beginners
> Go actually has one of the best WASM runtimes https://github.com/tetratelabs/wazero

Your game looks great, congrats on your progress! I especially enjoyed how the zoom works when you're leaving/arrive planets, and the unique propulsion system (also, the anchor made me giggle!).
> lack of data structure packages
I tend to not need many, so I'd be curious if you can recall any structure in particular which you couldn't find? No biggie if not.
> package structure not suited for games
I'm not a game dev, but I've seen some larger games such as https://github.com/divVerent/aaaaxy/tree/main/internal (if you haven't played it before—do it!) which seem to be able to place everything into separate packages without issue, so perhaps there's something to gleam from their design?
> maps are random when iterated
Hash map iteration shouldn't be sorted in _any_ language (here's Rust, for example https://play.rust-lang.org/?version=stable&mode=debug&editio... (Python makes it _appear_ as if dicts are sorted hash maps, but that's only because it doesn't only use a hash table, but a vector as well (same as you'd have to do in Go))), otherwise it would cause both portability and security (https://github.com/golang/go/issues/2630) issues. You can use a b-tree (which was probably the data structure you wanted there) if you aren't willing to sort it yourself.

Go actually has one of the best WASM runtimes https://github.com/tetratelabs/wazero
It also has a bunch of libraries for embedding scripting languages https://awesome-go.com/embeddable-scripting-languages, with Tengo _probably_ being quickest https://github.com/d5/tengo
I'd _highly_ recommend Ebitengine in the future, as not only have there been multiple brilliant games using it, but it also has Switch/Android/iOS support, and you can find help with any issue whatsoever in their Discord. People have built 3D games with it, and Hajime is an absolute beast of a developer.

WASM by Example
That depends entirely on the runtime, and its WASI implementation.
wazero [1], which I'm most familiar with, allows you to decide in a relatively fine-grained way what capabilities your WASI module will have: command line arguments, environment variables, stdin/out/err, monotonic/wall clock, sleeping, even yielding CPU… Maybe more importantly, filesystem access can be fully emulated, or sandboxed to a specific folder, or have some directories mounted read-only, etc; it's very much up to you.
I've used it to wrap command line utilities, and package them as Go libraries.
For one example, dcraw [2]. WASM makes this memory safe, and I can sandbox it to access only the single file I want it to process (which can be a memory buffer, or something in blob storage, if I want it to).
Wazero looks super cool. I saw somewhere that programs can be run with a timeout, which sounds great for sandboxing. The program input is just a slice of bytes [1], so an interesting use case would be to use something like Nats [2] to distribute programs to different servers. Super simple distributed computing!

Show HN: Sqinn-Go is a Golang library for accessing SQLite databases in pure Go
It is slower.
The WASM runtime wazero [1] uses a compiler on amd64 and arm64 (on Linux, macOS, Windows, and FreeBSD), but the current compiler is very fast (at compiling), but very naive (generates less than optimal code).
An optimizing compiler is currently being developed, and should be released in the coming months. I'm optimistic that this compiler will cover the performance gap between WASM and modernc.

Jacobin: Minimal JVM written in Go and capable of running Java 17 classes
I am a fan of the Jacobin project! For your uses, you may also want to consider wazero [1], a pure-go WebAssembly runtime. Full disclosure: I am on the team :)
