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.

Making Games in Go for Absolute Beginners
> It also has a bunch of libraries for embedding scripting languages https://awesome-go.com/embeddable-scripting-languages, with Tengo _probably_ being the quickest https://github.com/d5/tengo
Yes, I noticed those packages recently. The problem is that there is little data about how reliable and maintainable goloader is going to be on the long term.
As I care about performance and security, I don't want a scripting language, but WASM seems to be a very promising possibility. I have made benchmarks with 2~3 WASM engines in Go, and so far I am not completely convinced about the quality and performance of the available APIs. Also, when compiling Golang to WASM, the native compiler is still abysmally bad and does not have full support for imports, so Tinygo is a must-have.
Anyway, modding is still a long term idea at this point, so hopefully the ecosystem will get more mature within a couple of years.

Change go code behaviour at runtime
There are totally different things like https://github.com/d5/tengo but I don't know much about the docs, communities, or viability of them. Some like this one look very active and healthy. It might be worth considering.

Asking for advice to get deeper understanding of golang internals.
I started doing this a few years ago when I wanted to add programmability to another system I was working on, and didn't want Lua or anything else like that. I set it aside when other priorities arose, and didn't return to it when I saw that others had already done the same thing (yaegi, tengo).

Rust: Box Is a Unique Type
If you have an object that's !Unpin, then Miri will not apply uniqueness rules to anything containing it [0], including boxes and &mut references. (In the example code, replacing the PhantomPinned with a () will make Miri complain again.) This is considered a temporary (if long-lived) measure to allow async executors to manipulate pinned futures without invalidating all their references and whatnot. Thus, it might be seen as undetected UB, in lieu of a permanent solution.

Fivefold Slower Compared to Go? Optimizing Rust's Protobuf Decoding Performance
That would be true if you used `Vec::clear` too, it doesn't allocate a new vector. My point was that you still end up running Drop implementations with RepeatedField, just not all at once. See https://play.rust-lang.org/?version=stable&mode=debug&editio...

Borrow Checking Without Lifetimes
Self-referential structs work fine in Rust and always have.
https://play.rust-lang.org/?version=stable&mode=debug&editio...
The compiler will correctly prevent you from moving the value.
The other way to have a struct that starts out as non-self-referential and then becomes self-referential can be achieved with `unsafe` and `Pin::new_unchecked`, which is how `async {}` is handled.

On the other hand, both this wrapper and yours are counterproductive if the element size is dynamic (e.g. perhaps you're dealing with some nonsense like:)

New Linux glibc flaw lets attackers get root on major distros
Overflow checks turn into two's compliments' wrapping, but that's only considered acceptable because bounds checks are not turned off.

Atomics and Concurrency
I have no idea what you're talking about, but it sounds unnecessarily complicated and why I don't use Rust for any serious work.
This demonstrates the ABA problem in safe Rust: https://play.rust-lang.org/?version=stable&mode=debug&editio...
Substitute the sleep with a combination of doing computation/work and the OS thread scheduler, and you can see how the bug surfaces.
