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.

Logger Dependency Injection
For reference, here's my implementation. Note that my wrapper supports both structured and traditional logging APIs.

Choosing scripting extension - need advice
For JS in Go use goja, which offers excellent integration with Go. Also I maintain an extension that adds Common-JS compatibility to it.
-
golang logging
I think your instinct is right. For all my projects I use these wrappers. If you have any feedback or contributions they would be much appreciated. I know it's a losing battle, but there's no choice but to fight. Semper fi.

What I'd Like to See in Go 2.0
This is mostly what I did with my kutil logging library (sorry, no good documentation on how to use it yet). So I can use the same API in all my code and then pick various backends per project in order to better unify the log. For example, in Kubernetes I can use klog as the backend. I also wrote my own "simple" backend that does everything that I personally want. I'm sure there are other similar libraries out there.

Writing custom JSON and BSON marshal/unmarshaller for shopspring/decimal
I really like the idea of an Extended JSON, so I created my own version called "CJSON". The code is pretty straightforward.

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.

Show HN: Gsubpy, an interpreter for subset of Python, written in Go
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.
