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.

Autenticação com Golang e AWS Cognito
Primeiro vamos carregar nossas envs com o pacote godotenv, depois iniciamos nosso cognito client, passando o COGNITO_CLIENT_ID, que pegamos anteriormente, depois iniciamos o gin e criamos um server, isso é o suficiente.

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

Reading Environment Variable from a .env file on a Server
In his code it is done using https://github.com/joho/godotenv
- Libraries you use most of your projects?
-
Restful API with Golang practical approach
envconfig: Library for managing configuration data from environment variables (https://github.com/joho/godotenv)
-
Is this clear why its useful?
There is already a more complete, safer and neatly written godotenv alternative. It may be taken as an educational inspiration for next attempts.

I need some help setting up variables for the sake of my sanity
Chances are you are going to set them in you real server, and most likely you will going to use Linux for that. So for local development create a .env file with those in there. And at the start of you program, load them. You can use https://github.com/joho/godotenv Don’t share that file of course, and don’t put it in git.
