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.

What is the fastest way to encode the arbitrary struct into bytes?
For a similar case at MinIO we use messagepack - with tinylib/msgp.
- TinyGo Reflection?
- 80x improvements in caching by moving from JSON to gob

Are We Wasm Yet - Part 1
You might enjoy https://github.com/tinylib/msgp -- it's all code generation, tiny, and fast.

Best examples of a Go client
Feel free to compare the Go protobuf lib performance to https://github.com/tinylib/msgp -- the formats are similar enough, especially if you consider that protobuf is essentially a map[uint64]something container.

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.
