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.

Linus Torvalds adds arbitrary tabs to kernel code
Indentation by steps of 3 spaces is common in old Fortran 77 code. This is LAPACK for example. Scroll down to about line 400 to see actual code, not comments.

I think I've "fixed" some compiler errors from a lapack library (which conssisted of white spaces errors only that made the code not compile). Supposing that there was actual errors, how can I enter in contact to send the fixed code?
NETLIB LAPACK is currently tracked on GitHub https://github.com/Reference-LAPACK/lapack

LAPACKE_slacpy works correctly in C, but LAPACK_ROW_MAJOR results in unexpected behavior on SBCL
So, is this some bug resulting from an interaction of (i) LAPACKE not filling the transpose array with zeros (ii) LAPACKE_sge_trans writing the entire array (iii) compiler optimizing away writes from locations that the user never wrote to ?

Xkcd 2916: Machine
Ok, so this uses https://rapier.rs/ which is very cool
Rapier, alongside https://nalgebra.org/ (which it uses underneath) has seriously good documentation and some advanced features like cross-platform determinism (something made hard by the way floating point differs between platforms)

Geometric Algebra to Geometric Computing Software Developers
> Some GA libraries[1][2] define types for the different kind of objects (grades)
That's nice!
This reminds of me things like, linear algebra libraries that will type-check matrices so that a 2x2 matrix can't be added to a 2x3 matrix (but then you can have a dynamic matrix that will error only in runtime), like https://nalgebra.org/ and others.

Has anyone worked on a math library before?
Maybe start by looking at https://nalgebra.org/ to see what rust math libraries might look like

faer 0.8.0 release
And Nalgebra, while better, also seems to have slowed down on commits and responses to issues and PRs. I have a PR there for a relatively simple wrapper type for row vectors which was explicitly requested by a maintainer, which hasn't even gotten a comment since for two weeks.

Science-related crates that I should have a look at?
nalgebra is for linear algebra.

Hey Rustaceans! Got a question? Ask here! (31/2022)!
Take a look into math libraries, like glam, nalgebra, and cgmath. I've only used these through game engines, though, so I can't offer per-basis reviews/advice.

C++ is making me depressed / CUDA question
If you do not need GPU then I would recommend looking into Eigen in C++, nalgebra in Rust (with a BLAS in both cases for improved performance) or one of the above options (Julia / Python+JAX).
