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.

C++ for numerical programming
Some time ago, I started on a similar journey. Started with https://www.gnu.org/software/gsl/
-
C++ learning advice
I might recommend exploring some libraries that could be used. GSL https://www.gnu.org/software/gsl/ is an example. This might be an equivalent of NumPy.

Building an online image compressor
After some research, I found libvips, a demand-driven, horizontally threaded image processing library. It is designed to run quickly while using as little as memory as possible.
-
Things you might not know about Next Image
Sharp is a fast and efficient image optimization Node.js module that makes use of the native libvips library.
-
Go Image Converting
h2non/bimg can handle both if the underlying libvips is compiled with support for both formats.
-
.Webp is the bane of my existence
if you're using linux (which it doesn't seem so) there's also vispdisp https://github.com/jcupitt/vipsdisp which is based on https://github.com/libvips/libvips which will likely take over how images are decoded in the future for everything, at least methodology wise.
-
How are responsive image sets are generated, stored, and managed server-side?
The magic happens by way of a library called Libvips, which contains an ultra-high-speed low-memory image resizer.
-
imagor v1 - a fast, Docker-ready image processing server in Go, libvips and more
imagor uses one of the most efficient image processing library libvips. It is typically 4-8x faster than using the quickest ImageMagick and GraphicsMagick settings.
-
My project: railstart app
libvips v8.6+ or ImageMagick for image analysis and transformations
-
railstart-niceadmin support more features

-
Fast, Docker-ready image processing server written in Go and libvips, with Thumbor URL syntax
That's very cool! Though performance will not be close -- your nice solution is based on libgd, which is typically 5x slower than libvips, and needs 10x more memory. At usual display sizes, libvips will generally deliver the resized image in under 50ms, and will handle large images (relatively) gracefully.
