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 are strings and IO so complicated?
std::ranges is in c++20, but you can pull in the library it was based on if you use 17 (https://github.com/ericniebler/range-v3)

Java Streams in c++
What you are describing seems to be std::ranges. If you’re interested in understanding how to implement it, I recommend checking out the original reference implementation, rangev3. Trying to implement your own ranges framework is really good practice for learning how to do efficient, advanced generic programming in C++. I highly recommend it as a hobby learning project. But it’s also really, really hard to do correctly, so please just use the stdlib and/or rangev3 in any real project.

What are some of the ways to make a super nasty nested loop become clean?
In C++23, there will be std::views::cartesian_product. It is already available in the range-v3 library, the one that the standard is based on.

Is there an <algorithm> way to filter + transform multiple containers at once
It uses a custom zip_iterator (which isn't very good, and you should really use the one from boost or from range-v3).
-
what annoys you most while using c++?
It contains very little functionality compared to the Eric Niebler’s reference implementation for my liking. Especially views. This will undoubtedly change in the future. But the point is moot, because they are not really supported the is no other option for now other than https://github.com/ericniebler/range-v3.

CXXIter: A chainable c++20 LINQ-like iterator library
[range-v3](https://github.com/ericniebler/range-v3) which std::ranges was based on has the `to>()` which as far as I know is expected to get into c++23 :)

Rust's recursive directory iterator 5x faster than CPP
On C++ side you may also try ghc::filesystem. It may cache more data fro directory entry.
