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).

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?

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.

Finding unreachable functions with deadcode – The Go Programming Language
One of the checkers in golangci-lint does this. I forget which one.
golangci-lint rolls up lot of linters and checkers into a single binary.
There is a config file too.

Using Private Go Modules with golangci-lint in GitHub Actions
golangci-lint is an amazing open-source tool for CI in Go projects. Basically, it's an aggregator and a Go linters runner that makes life easier for developers. It includes all the well-known liners by default but also provides an easy way to integrate new ones.

Show HN: Error return traces for Go, inspired by Zig
The "standard linter" in Go is https://golangci-lint.run/ , which includes [1] the absolutely-vital errcheck which will do that for you.
For an Advent of Code challenge you may want to turn off a lot of other things, since the linter is broadly tuned for production, public code by default and you're creating burner code and don't care whether or not you have godoc comments for your functions, for instance. But I suggest using golangci-lint rather than errcheck directly because there's some other things you may find useful, like ineffassign, exportloopref, etc.

Hacking Go to give it sum types
golangci-lint recently integrated go-check-sumtype. I recommend using golangci-lint as a pre-commit hook, but if you're in a real hurry you can replace "go build" with a shell script that runs go-check-sumtype instead. This is probably better than a weird hack, not that you're saying that the weird hack is a good idea anyhow.

Structured Logging with Slog
This is such an infuriating problem. I'm convinced I'm using Go wrong, because I simply can't understand how this doesn't make it a toy language. Why the $expletive am I wasting 20-30 and more minutes per week of my life looking for the source of an error!?
Have you seen https://github.com/tomarrell/wrapcheck? It's a linter than does a fairly good job of warning when an error originates from an external package but hasn't been wrapped in your codebase to make it unique or stacktraced. It comes with https://github.com/golangci/golangci-lint and can even be made part of your in-editor LSP diagnostics.
But still, it's not perfect. And so I remain convinced that I'm misunderstanding something fundamental about the language because not being able to consistently find the source of an error is such an egregious failing for a programming language.
