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.

Modern C++ Programming Course
You can definitely start putting C++ into your embedded projects, and get familiar with things in an environment in which you're already operating. A lot of great C++ code can be found with motivated use of, for example, the platformio tooling, such that you can see for yourself some existing C++ In Embedded scenarios.
In general, also, I have found that it is wise to learn C++ socially - i.e. participate in Open Source projects, as you learn/study/contribute/assist other C++ developers, on a semi-regular basis.
I've learned a lot about what I would call "decent C++ code" (i.e. shipping to tens of thousands, if not hundreds of thousands of customers) from such projects. I would suggest finding an open source C++ project, aligned with your interests, and study the codebase - as well as the repo history (i.e. gource) - to get a productive, relatively effortless (if the interests align) boost into the subject.
(My particular favourite project is the JUCE Audio library: https://juce.com/ .. one of many hundreds of great projects out there from which one can also glean modern C++ practices..)

Anyone here have experience writing VST audio plugins in C++, or 'wrapping'/converting a VST to an AU plug-in?
It seems like most audio plug-ins are built in C++ inside an audio coding program called JUCE, so maybe if I could open up the exisiting code inside that and then output it as an AU instead of a VST that could work.

Ask HN: What audio/sound-related OSS projects can I contribute to?
JUCE:
Tracktion:
Both very powerful audio frameworks - JUCE does plugins and audio drivers and low-level DSP, oh my - and Tracktion does all the stuff a DAW needs, on top of JUCE.
There are tons of ways to contribute, from building open source samples, to testing, or even adding functionality. Both dev teams are open to good quality PR's being submitted and both frameworks have excellent communities that will get you started: http://forum.juce.com/
These are cross-platform tools which offer Audio developers an extremely powerful toolset. By contributing to either (or both) frameworks you will be massively contributing to the audio world - so many plugins use JUCE these days!
- Recommendation for professional open source project where we can learn best practices, contribute and improve coding knowledge simply by looking at the code?

Leveraging Rust and the GPU to render user interfaces at 120 FPS
> Juce has a CoreGraphicsMetalLayerRenderer which I believe uses Metal to render CoreGrapghics primitives.
This class is part of a JUCE demo app, and you can read the source code to it if you want. [0] It uses CoreGraphics to render the graphics on the CPU, and then uploads it as a texture to the GPU so it can be used as a CAMetal layer. So, no, the graphics are still rendered on the CPU, with compositing being handled on the GPU.
> For example, I heard that UE4->UE5 removed the GPU tesselation support
I know it's confusing, but GPU tessellation is a completely different thing. The word "tessellation" in graphics means "turn into triangles". In a 2D graphics context, we're turning splines and curves and 2D shapes into triangles. In a 3D graphics context, GPU tessellation refers to a control cage mesh which is adaptively subdivided. These two have nothing in common except that triangles come out the other side. I am not aware of anyone who has tried to use GPU tessellation to render 2D graphics.
GPU tessellation failed for a large number of reasons, but slow performance was one of them. So, you know, doing this sort of work efficiently on the GPU is still an open research problem. Just because it's not efficient to do it on the GPU does not mean the performance overhead is negligible. For rendering big complex vector graphics, tess overhead can easily outweigh rasterization overhead.

When we talk about 2D graphics as a research problem, we're talking about native rendering of splines and strokes. JUCE does not have GPU-accelerated splines, it flattens the path to lines and rasterizes the coverage area into a texture.

It also does stroke handling on the CPU:
https://github.com/juce-framework/JUCE/blob/2b16c1b94c90d0db...
Basically, this isn't really "GPU accelerated splines". It's a CPU coverage rasterizer with composting handled by the GPU.
You linked to the compatibility-renderer. But JUCE also has platform-specific rendering modules.
CoreGraphicsContext::createPath will convert the CPU spline segments to CG spline segments which are then rasterized by CoreGraphics using Metal on the GPU.

SDL, SFML, other libraries for game development in C++...?
I only used SFML, currently making a 2D isometric game. I really like it so far overall, easy to use IMO, pretty well documented. Does what I need it to do. Heard good things about SDL2 and also Cinder++ (https://libcinder.org/) also.

What kind of game? You might be better off using a game engine unless it's more of a simple starter project. Check out https://libcinder.org/ or see lots of engines here: https://github.com/collections/game-engines

Something like p5.js but for C++
Try Cinder (https://libcinder.org/). I have not tried it myself but it seems to have the same goals as P5 and Processing (ie. creative coding).

Getting started with graphics programming on a mac?
Depends on what kind of graphics programming you are wanting to do. If you are looking towards like experiential or generative or stuff of that ilk, I'd look at https://libcinder.org or https://openframeworks.cc
- If you're having trouble getting OpenGL stuff to compile, while I have not checked on Monterey, things like openFrameworks and Cinder still compile fine on Mac last I looked. Granted you're still limited to certain OpenGL versions but that's at least something to try to get started.

Tool for visualizing simulation
I looked far and wide and here's what I got: - OpenGL: It lets me do everything I want, but I also have to start from scratch (camera matrices, input handling, shader programming, etc). - Abstractions over OpenGL ((Cinder)[https://libcinder.org/] and (Magnum)[https://magnum.graphics/]): Easier to use when compared to pure OpenGL, but they still require a considerable amount of manual work to get them to show hair strands on screen. - Game engines: I still haven't tried any, but my concern is whether or not they would let me use my own code to do all the simulation (collision detection, movement computation, etc).
