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.

Trouble understanding rounding when the next digit is after round precision is a #5?
Try it in JS with console.log(4.225 * 100);, you'll see the same unexpected result. Depending on your needs, it's actually fine to just be off by some amount. If it does really matter, then use an arbitrary precision library like https://github.com/shopspring/decimal to get the results you need.

Handling currency values: facts and best practices
Most programming languages ( JavaScript, PHP, Go, Python, Java, C# ) have built-in support or 3rd-party libraries for handling this data type, even though the internal implementations can differ:

Any go and python number experts here?
while working with money, dont use floats, use something like https://github.com/shopspring/decimal (go std lib doesnt have its own decimals yet)

my first golang project!
Integers, or something like this: https://github.com/shopspring/decimal

80x improvements in caching by moving from JSON to gob
I make heavy use of caching, and was caching both in-memory and in Redis using JSON to convert the data in to a string. The struct itself isn't super complicated, one level nested, and some fields use the shopspring/decimal library.

Unexported interfaces usage question
I actually use this to represent monetary values btw :)

How to round(2) float64?
Check out https://github.com/shopspring/decimal for doing money related calculations.
-
Library recommendation -- money calculations, more accurate handling of floats
We personally use https://github.com/shopspring/decimal and it works well.
-
What are your favorite packages to use?
decimal, one of the first Go library that created to work with decimal and monetary value.
-
What libraries from other languages do you wish were ported over into go?
https://github.com/shopspring/decimal also.

Go 1.21 Released
Be aware that there is a performance impact compared to using zerolog directly [0] (my uneducated guess is it is likely due to pointer indirection).

How to start a Go project in 2023
Things I can't live without in a new Go project in no particular order:
- https://github.com/golangci/golangci-lint - meta-linter
- https://goreleaser.com - automate release workflows
- https://magefile.org - build tool that can version your tools
- https://github.com/ory/dockertest/v3 - run containers for e2e testing
- https://github.com/ecordell/optgen - generate functional options
- https://golang.org/x/tools/cmd/stringer - generate String()
- https://mvdan.cc/gofumpt - stricter gofmt
- https://github.com/stretchr/testify - test assertion library
- https://github.com/rs/zerolog - logging
- https://github.com/spf13/cobra - CLI framework
FWIW, I just lifted all the tools we use for https://github.com/authzed/spicedb
We've also written some custom linters that might be useful for other folks: https://github.com/authzed/spicedb/tree/main/tools/analyzers

claim: qlog is faster, simpler and more efficient that slog; and does more practically useful stuff too
Can you compare it against zerolog?

Zerolog printing logs multiple times
Hello gophers, I am using https://github.com/uber-go/fx and https://github.com/rs/zerolog for logging.

Doubt around "Test only public functions" concept
Hovewer it is not bad to export such a function, if it is done purely for convenience. For example github.com/rs/zerolog works on a logger instances, which can be created manually, but they also provide a github.com/rs/zerolog/blob//log package, which provide you access to the global logger which is more convenient in most cases

Tools besides Go for a newbie
IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here

What is the common log library which is industry standard that is used in server applications?
I use zerolog myself and have seen it being used in production several times. Also they have a list of who uses zerolog

Log: A minimal, colorful Go logging library 🪵
This would be so awesome if it was extending an awesome logger like https://github.com/rs/zerolog. Personally I love zerolog because of how it handles different data types including structs!

Best Logging Library for Golang
logrus README recommended using other libraries such as Zerolog, Zap, and Apex.
- If you had to choose a logging framework, which one would you use?
What are some alternatives?
Golang Crypto Trading Bot - A golang implementation of a console-based trading bot for cryptocurrency exchanges
zap - Blazing fast, structured, leveled logging in Go.
decimal - A high-performance, arbitrary-precision, floating-point decimal library.
logrus - Structured, pluggable logging for Go.
go-money - Go implementation of Fowler's Money pattern
lumberjack - lumberjack is a log rolling package for Go
go-finance - :warning: Deprecrated in favor of https://github.com/piquette/finance-go
glog - Leveled execution logs for Go
Testify - A toolkit with common assertions and mocks that plays nicely with the standard library
Gin - Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin.
apd - Arbitrary-precision decimals for Go
log - Structured logging package for Go.
