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.

A Dive into the Math Behind Bitcoin Schnorr Signatures
I was searching for implementations to get a more concrete idea of the algorithm and came across https://github.com/Yawning/secp256k1-voi which appears to be well commented, robust, and often also entertaining. There’s also a musig2 one by the same author.

A beginner's guide to constant-time cryptography (2017)
I noticed in July of 2022 that Go did exactly the vulnerable example and reported it to the security team.
https://github.com/golang/go/issues/53849
It was fixed as of Go 1.21 https://go.dev/doc/go1.21

The article cites JavaScript, which is not constant time. There's no sure way to do constant time operations in JavaScript and thus no secure way to do crypto directly in Javascript. Browsers like Firefox depend on low level calls which should be implemented in languages that are constant time capable.
JavaScript needs something like constant time WASM in order to do crypto securely, but seeing the only constant time WASM project on GitHub has only 16 stars and the last commit was 2 years ago, it doesn't appear to have much interest. https://github.com/WebAssembly/constant-time
However, for JavaScript, I recommend Paul's library Noble which is "hardened to be algorithmically constant time". It is by far the best library available for JavaScript. https://github.com/paulmillr/noble-secp256k1
