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.

Prima has got a Python interface
The developer of PRIMA here.
If you use method "cobyla" from scipy.optimize.minimize, then PRIMA already performs far better (in terms of the number of function evaluations). See the comparison at https://github.com/libprima/prima#improvements .
The bugs are indeed only a secondary reason: they can only be triggered under special situations. They may not affect your usage at all (when it does affect you, the consequence is catastrophophic).

Nagfor supports half-precision floating-point numbers
1. nagfor Release 7.1(Hanzomon) Build 7149 released on March 5, 2024, fixed all the bugs spotted, but introduced an ICE when compiling PRIMA ( http://www.libprima.net ). The ICE has nothing to do with half-precision real, because it occurs when PRIMA is configured to use single or double precision. It can be reproduced by
```
git clone https://github.com/libprima/prima.git && cd prima && git checkout ec42cb0 && cd fortran/examples/lincoa && make ntest
```
2. nagfor 7.2 released on 6 March, 2024 included neither the ICE nor the fixes for the bugs.

What are you rewriting in rust?
My goal is to rewrite this library for derivative-free optimization: https://github.com/libprima/prima

SciPy: Interested in adopting PRIMA, but little appetite for more Fortran code
A native port is indeed planned. However, since we are talking about a project of about 10K lines of code, such a port will not be delivered very soon.
In fact, native implementations of PRIMA in Python, MATLAB, C++, Julia, and R will all be done in the future. See https://github.com/libprima/prima#other-languages . But it takes time. PRIMA has been a one-man project since it started three yearss ago. Community help is greatly needed.
Thanks.

Optimization Without Derivatives: Prima Fortran Version and Inclusion in SciPy
It sounds like this was a difficult task. The motivation to fulfill Prof. Powell's request and help the community of derivative-free optimization users must have been strong. Congratulations on your achievement!
From the GitHub README:
> In the past years, while working on PRIMA, I have spotted a dozen of bugs in reputable Fortran compilers and two bugs in MATLAB. Each of them represents days of bitter debugging, which finally led to the conclusion that it was not a problem in my code but a flaw in the Fortran compilers or in MATLAB. From a very unusual angle, this reflects how intensive the coding has been.
> The bitterness behind this "fun" fact is exactly why I work on PRIMA: I hope that all the frustrations that I have experienced will not happen to any user of Powell's methods anymore. I hope I am the last one in the world to decode a maze of 244 GOTOs in 7939 lines of Fortran 77 code — I have been doing this for three years and I do not want anyone else to do it again.

Suggest some local music player for debian based distros
Gmusicbrowser is pretty good feature-wise. It's very configurable and has many different layouts. It might not look very modern by default, but with a modern gtk theme and some fiddling it looks okay to me at least.

Prima: Cross-platform GUI toolkit written in Perl
Perl actually had a pretty good UI story way back when. Perl/Tk always was well documented and Perl's syntax works quite well with the original Tcl-ish/Shell style.
Note that GIT's default GUI parts are written in exactly that.
Tk then hit a bit of a limit when it came to common widgets, and so got less popular.
Perl also had a good implementation of Win32, if I remember correctly.
These days, both Perl and GUIs are on a steady decline, so there's not much moving in that space. Gmusicbrowser[1] is written in Perl/Gtk, if I remember correctly.

Music player recommendations with a few requirements
Gmusicbrowser is great, very customizable.

There seems to be no Linux music player that supports reading and writing to the POPM rating tag, and making smart playlists based on both those ratings and other playlists. Or, "I really freaking miss MusicBee, man"
