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.

Rapier is a set of 2D and 3D physics engines written in Rust
I got sucked down a Geometric Algebra rabbit hole a few months ago, which seems like a remarkably concise and intuitive way to work in a very wide variety of geometries, including 2D, 3D, 4D+, non-euclidean etc. I've wondered if GA would make a good foundation for a physics engine...
There are a few small rust libraries that look interesting [1][2], but none with a lot of traction.
Has anyone looked into this?

Geometric Algebra to Geometric Computing Software Developers
The GA community in general is very small. So yes, tooling could be better, but IMO that is not even the problem. The lack of understanding how to use it is, because GA is not explicitly taught in schools or universities.
I have written a compiler which generates SIMD ready code for the desired GAs. You can then use that output as a normal library for your application.

Maybe the folks at Rerun [1] know something about it? I imagine at least some of their customers are Rust robotics shops.

Rerun 0.9 – a framework for visualizing streams of multimodal data
No specific support for audio embeddings yet, though depending on you're specific use-case, you might be able to map your data to more generic primitives such a TimeSeriesScalar, LineStrips2D, BarChart, or Tensor.
We have an open issue for adding more support for audio-based projects -- if you have specific needs feel free to add a comment: https://github.com/rerun-io/rerun/issues/2852

Real-Time Visualization of Streaming Data in Python with ReRun
https://github.com/rerun-io/rerun is such a great tool for creating interactive dashboards to look at real-time data. Curious if there are others looking for something like this and what the other use cases would be interesting. I have heard ideas like:

Considerations for Power Draw with egui
To test the power draw, I conducted an unscientific experiment by circling the cursor over both a GTK4 app (GNOME Console) and an egui app (Rerun Viewer), while monitoring the CPU/GPU utilization and stabilized power draw with PowerTOP. The results indicated that when circling the cursor over the GTK4 app, the CPU/GPU usage was nearly negligible, and the stabilized power draw was around 13 W. In contrast, when circling the cursor over the egui app, the CPU/GPU usage was considerably higher, resulting in a stabilized power draw of around 21 W. This amounts to an increase of approximately 60%. Taking into account a power draw of around 10 W when doing nothing at all, the increase becomes roughly 260%. I also tried the same experiment with Iced, and while the increase was not as extreme, it still utilized resources when circling the cursor over a blank surface.
