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.

Compile-time safety for enumerations in Go
This is an analyzer that will catch this: https://github.com/nishanths/exhaustive
I believe it's in golangci-lint.

Tools besides Go for a newbie
I agree linters in general are quite useful for Go though. The default suite from golangci-lint is quite good. I would also recommend enabling exhaustive if you're working with a codebase that uses "enums" (full disclosure, I contributed a bit to that project).

What “sucks” about Golang?
there’s a linter for exhaustive matching: https://github.com/nishanths/exhaustive

Rusty enums in Go

Supporting the Use of Rust in the Chromium Project
And in Go you'd use a linter, like this one.

Blog on enums in Go: benchmarks; issues; assembly
this is AST go vet analyzer that performs just that: https://github.com/nishanths/exhaustive (too bad it can not do struct based enums..)

Rust Is Hard, Or: The Misery of Mainstream Programming
>> the main thing missing from Go is ADT's. After using these in Rust and Swift, a programming language doesn't really feel complete without them
What are the differences between an ADT (plus pattern matching i’d reckon?) in Rust/Swift vs the equiv in Go (tagged interfaces + switch statement)?
One has exhaustive matching at compile time, the other has a default clause (non exhaustive matching), although there’s an important nub here with respect to developer experience; it would be idiomatic in Go to use static analysis tooling (e.g. Rob Pike is on record saying that various checks - inc this one - don’t belong in the compiler and should live in go vet). I’ve been playing with Go in a side project and using golint-ci which invokes https://github.com/nishanths/exhaustive - net result, in both go and rust, i get a red line of text annotated at the switch in vscode if i miss a case.
Taking a step back, there isn’t a problem you can solve with one that you can’t solve with the other, or is there?
To take a step further back, why incomplete?

Why are enums not a thing in Go?
Use a linter.

1.18 is released
For an exhaustive linter, were you referring to this? It looks pretty nice. If it's possible to check this with static analysis, is it something that could be in the compiler itself in the future?

Go Replaces Interface{} with 'Any'
https://github.com/nishanths/exhaustive
here, have fun. You’re gonna write some tests, make new types to satisfy interfaces for testing, and then wind up with branches for your test paths in your live code, but go for it, I guess. You know everything! I am but a simple blubbite, too dim, too dim to get it.

Good Books for a GO Beginner in 2023/24
Go never changed as much as Java does in each major release, so old books are still relevant. https://www.gopl.io/ is fine if you read about generics and some new standard library modules somewhere else later.

Does anyone have any good resources to practice channel, context, and goroutine?
Not that they are leet code style, but some exercises from "The Go Programming Language" are really worth having a look at, also most solutions are available at https://github.com/adonovan/gopl.io
- Best way to learn GoLang for Java Developers?
- How similar is GO to C?
-
is go still simple?
What part(s) are you struggling with and how are you learning? The Go Programming Language is slightly outdated but is an excellent intro. You can read the first chapter free. Also the resources on https://go.dev/learn/ are great. If I were you, I would come up with an idea you're excited about and build it.

Learning about concurrency
For a deeper dive, I’d recommend The Go Programming Language - a fantastic resource covering a broader landscape of the language than just concurrency.
-
If you want to learn Golang - please go through "Go Programming Language" by Brian Kernighan and Alan Donovan
"Low-level programming" is chapter 13, both in the version I have and on https://www.gopl.io/ -- the rest is all somewhat crucial stuff, except for maybe reflection.
