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.

completed 80 questions of leetcode in golang😊
The disadvantage is it lacks some features necessary to scale nicely to huge codebases. Large projects end up using source code generation and other hacks. i.e. https://github.com/kubernetes/gengo
- Not giving the programmer a choice and forcing them to be pragmatic was one of the main selling points of Go. Allowing generics at all will likely make them seep into the ecosystem over time and destroy part of that value proposition.

What are the cool kids learning these days?
Go also doesn't scale on a large codebase. you end up using hacks like source generation (https://github.com/kubernetes/gengo) and static analysis to make up for the shortcomings of the language. The jvm or .net have better tools for dealing with complexity imo. Jvm langs can compile to bin with graal.

Show HN: Error return traces for Go, inspired by Zig
Can you explain why we should this over https://github.com/pkg/errors?

Cant wait for less verbose error handling
The pkg/errors package offers some nice add-ons for easier error handling. Too bad it was put into maintenance mode pending whatever changes/improvements are coming in Go 2.

isse for go path in neovim
I can't figure out the issue so here for some help, I am using `neovim/nvim-lspconfig` my `gopls` doesn't recognise external paths such as `github.com/pkg/errors` , it throws error`could not import github.com/pkg/errors (cannot find package "github.com/pkg/errors" in any of /usr/local/go/src/github.com/pkg/errors (from $GOROOT) /Users/ra compiler (BrokenImport)\`
-
What am I supposed to be doing with errors?
Also - there are some error handling utils that allow you to wrap errors before passing: https://github.com/pkg/errors
-
Go error handling is not verbose but the error handling itself.
Should've been something like errors.Newf("failed to foofoo %s", foo) instead and preferably never invent %w but have some controlled way to wrap like errors.Wrapf(err, "failed to foofoo %s", foo) that was in ye olde github.com/pkg/errors.
-
How to wrap the error best?
Prefer using errors.Wrap and errors.Wrapf from https://github.com/pkg/errors . It's frozen because they don't want to add features, waiting for a re-write of error handling in Go2.

Getting at the type of error after it has been wrapped with errors.Wrap
Im using zerolog and in order to get the stack trace for my error I have to wrap my error in errors.Wrap from "github.com/pkg/errors".
-
When ia a good time to panic?
And for "real programs" you can use https://github.com/pkg/errors (if you want stack traces)
