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.

Why is this piece of code compiling with char as c-tor argument?
Yep. And there are some libraries to provide strong-type int, depending on what you need: type_safe or even units.
-
its okay guys they fixed it!
Which programming language has, by default, a float type between 0.0 and 1.0? I think it is solvable with libraries in some languages, sure, but it is there in the type system or the standard library of some mainstream language?

Optional output arguments
Consider taking a look at the type_safe library https://github.com/foonathan/type_safe which has an output_parameter type

Integer Conversions and Safe Comparisons in C++20
foonathan/type_safe provides wrappers around standard types that prevent most of the unwanted implicit conventions. Also it provides backport of safe comparasions on C++11 and C++14

Things You Should Do Now
I agree, the 'microtype' pattern can be a good way of getting the type-checker to catch silly mistakes.
In Ada it's standard practice. In C++ you really need a library to do it easily, but there's a good one out there ready to go:

Is it just mean, or is C# easier to learn than JavaScript or even PHP?
It's not the type system you're complaining about, though. It takes a bit of work but you can write types that include units information with no loss of performance.

I'm a beginner making a library for unit conversion, contributions are welcome
I recommend using this as reference https://github.com/mpusz/units it probably solves the same or similar problem.

C++'s smaller cleaner language
Indeed you cannot. Then again, you couldn't write a library like fmtlib in C in the first place. I mean why do you complain about C++ features which enable you to write libraries you otherwise couldn't? How would you expect to implement equivalent libraries to EVE or mp-units in C alone?

I got curious about units of measure in programming languages so I recreated xkcd/687.
How does it compare with https://github.com/mpusz/units ?

Please Put Units in Names
Good C++ library for that topic is [0]. You can even go further and combine with something like [1] which is super helpful for kalman filters and other stuff where you have heterogeneous units in one vector.
