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).

Python Is Easy. Go Is Simple. Simple = Easy
Starlark in go https://github.com/google/starlark-go is a great way to combine the best of both, the ease of use of Python and the simplicity of go.
I have been building a platform for deploying internal web applications using this approach https://github.com/claceio/clace. Use Starlark to configure the application, the platform itself is built in go.

Examples of using task scheduler with Go?
The big unknown is your task definition: what does user-defined logic look like? If you're expecting go code, that's gonna need some cleverness because of the compiled nature of it. There's a node runtime implemented in go if you want to provide sandboxed javascript (check the source of k6.io, it's the main one I know that uses it). If you want to provide building blocks and let them compose them, starlark might be a good choice.

Another one of those (with broader language support) is the Starlark language, which has a Go implementation: https://github.com/google/starlark-go

Looking for library to build composable actions from config file
Every config format gets as complex to be touring complete in the end. We had similar problems and eventually got rid of that complexity and switched to starlark (the bazel config language), was a huge benefit for the tools. https://github.com/google/starlark-go "Starlark is a dialect of Python intended for use as a configuration language. Like Python, it is an untyped dynamic language with high-level data types, first-class functions with lexical scope, and garbage collection."

Change go code behaviour at runtime
For a Python-like syntax, https://github.com/google/starlark-go is the language used in Babel. It's very mature, but since it is used in a massive mature project with a specific purpose, it doesn't move fast or drift from the spec of its Java-based sibling. It doesn't have exception try except blocks or some other features you might expect, but for short extension logic, it might be exactly what you want with the stability you can depend upon.

Reserve 4 gigabytes and treat any pointer in that range as an integer value

A command-line tool to create development environments for AI/ML, based on Docker and buildkit
Thus envd is more like Dockerfile, while it uses a simplified python dialect starlark https://github.com/google/starlark-go as the build language.
