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.

I've been learning Rust for 3 days and this is my first impression
Use num: https://github.com/rust-num/num
- BigInts in std?

A single issue with Rust that kills me every time with mathematics (rust repo issue 20671)
The num crate is worth a look - they do implement some of these things via macros. https://github.com/rust-num/num

Donald Knuth’s Algorithm D, its implementation in Hacker’s Delight and elsewhere
Here is my optimized in-place Rust implementation [1].
It is a very tricky algorithm to get right. There are many edge cases that only happen for ~2^-64 fractions of the input space, so hard to find even with fuzz-testing. Best strategy is to implement it for small limbs first, and fuzz that well.

A single issue with Rust that kills me every time with mathematics (rust repo issue 20671)
I've also hit this issue while writing code generic over prime fields by-reference. I ended up defining traits FieldLike and RefFieldLike and anotating all functions as
