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.

Have you used generics?
I made a package like that: https://github.com/carlmjohnson/be. It’s probably my most frequent use of generics.

alecthomas/assert: A minimalist type-safe drop-in replacement for testify/require
I spent the last week working on one of these: https://github.com/carlmjohnson/be. Some initial thoughts I have are that the error messages basically don’t matter because if the test fails you’re going to dig into the line where the failure happens anyway.

Visualizing Diffs The Myers difference algorithm
This made me think of a couple other interesting things:
1. you can change which algorithm is used in git diff as multiple are supported

2. Google has an edit graph implementation in Go in the cmp package

How do you do DB preparation in e2e tests?
Assertion libraries that people seem to love: - testify (my favorite) - go-cmp is a more barebones library - gotest.tools -- I have never used this but some swear by it

it uses https://github.com/google/go-cmp instead of reflect.DeepEqual

What annoys you about Go?
When I use functional arguments, I either prefix all of the options with the same prefix or put them in a dedicated package (like cmpopts) to help the IDE.

What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

Go Package for Equality: github.com/google/go-cmp
One thing to keep in mind about reflect.DeepEqual is because of the way it is implemented you could get positive results when the values are not actually the same, see this comment for reference.
What are some alternatives?
graph - A library for creating generic graph data structures and modifying, analyzing, and visualizing them.
Testify - A toolkit with common assertions and mocks that plays nicely with the standard library
scan - Scan provides the ability to to scan sql rows directly to any defined structure.
ginkgo - A Modern Testing Framework for Go
GoAws - AWS (SQS/SNS) Clone for Development testing
