The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Kafka as chat server?
Redis. The pub/sub is sufficient. Here's a notification service that plugs websockets in on one end: https://github.com/go-bridget/notify - I might add in server-side push support, or gobws to keep memory use down. A chat service can be implemented with a rpc API for write operations, and the notify websocket service to deliver events (new messages,...) and state (history, search,...).

Migrating from PHP to Go
I'm a big fan of [Twirp RPC](https://github.com/twitchtv/twirp), and [go-chi/chi](https://github.com/go-chi/chi) if I need to provide REST endpoints, authentication or other routing middleware. The "gorilla" set of packages are also useful, I always reach for gorilla/websocket if I need to do some websocket work. You can look at an example service in [go-bridget/notify](https://github.com/go-bridget/notify) - the main files to look at are under rpc/notify/notify.proto/.go, and the implementation which you write is under server/notify. If you'd create database drivers, I'd create a package under server/notify/mysql (for example), and then implement an interface for data retrieval/settings. It's on the todolist, if I'll ever need to implement anything other than JWT, or Redis. Comment if you have any questions or notes.

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

alecthomas/assert: A minimalist type-safe drop-in replacement for testify/require
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.
