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.

Nannou – An open-source creative-coding framework for Rust
I mean, https://www.libcinder.org and https://openframeworks.cc have been mainstays of the creative coding industry for a long time now. A Rust take on the problem shouldn't be too surprising.
OpenFrameworks[0] is quite popular for creative coding even though it's written in C++ - framework is actually pleasant to use. If you want to do some creative coding on both iOS and Android you don't have many options. If you want to use sensors (cameras, microphones, gyroscope, accelerometer, etc) and e.g. process video stream at 120fps you have even less choices.
Sadly OpenFrameworks development seems kind of stalled. Nannou + Rust could be a good or even better alternative:
1) painless cross-compilation to different platforms
2) plugins installation via cargo
3) more up-to-date plugins as tiny wrappers around CPAL [1] (audio I/O), nokhwa [2] (video i/o), opencv-rust[3] (video I/O and processing), rust-sdl2 [4](IMU sensors + game controllers), egui [5] (immediate mode gui + plotting)
4) better errors and more modern language

Launching glitchIO pocket glitch art app on iOS with oF
glitchiO is a piece of visual generative Pocket Art for mobile phones and tablets that explores the space inside randomness and glitch. It is inspired by the analogue VHS tape noise of damaged video cassettes and dirty playback heads on domestic VCRs. Reimagining this space for contemporary digital media and mobile phones glitchiO is a contemplation and treatise on what it is to hear machines speak in the interstitial spaces between human defined functions.Using touch gestures and accelerometer you can navigate the visual world of noise, glitch, randomness and higher stochastic functions. you can download it for free from the Apple app store here https://apps.apple.com/app/id1620340485you can find the source code using openFrameworks here on my github pages https://github.com/danbz/glitchiO glitchiO is crafted with pride using openFrameworks artists C++ toolkit. http://openframeworks.cc
