The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Making large line-charts (visualizations) scalable with plotly-resampler
Looks great! I have been using https://github.com/urschrei/simplification Visvalingam-Whyatt algo as per suggestion of Mike Bostock https://bost.ocks.org/mike/simplify/, don't know if it's comptetitive with the EffLTTB. It is surposesd to be fast and good in terms of shape preservation.

Julia is the better language for extending Python
Rust doesn’t need to copy the data. It’s trivial to pass e.g. Numpy arrays to Rust as slices via Cython (let alone originating in Cython!), modify them, and return them, or use them as input for a new returned struct.

Each of those repos has links to the corresponding Rust “shim” libraries that provide FFIs for dealing with the incoming data, constructing Rust data structures from it, and then transforming it back on the way out.
As a more general comment, using a GC language as the FFI target from a GC language is begging for difficult-if-not-impossible-to-debug crashes down the line.

downsampling 500M datapoints in < 0.05s
We plan to integrate this in our (already quite scalable) time series visualization library https://github.com/predict-idlab/plotly-resampler - should further increase the scalability by a factor 10 :)
