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.

Different algorithms for converting binary to decimal floating-point numbers
In Java, many number-to-string implementations use NumberFormat. This is abysmally slow if the problem domain doesn't require internationalization, which is the case for machine-readable file formats, such as SVG. When I performance tested JMathTeX for rendering TeX, the bottleneck for converting TeX into SVG elements was JFreeSVG's use of NumberFormat[0]. Replacing NumberFormat with RyuDouble doubled the throughput[1]. (Reusing a StringBuilder for to concatenate strings yielded another doubling.)
For KeenType[2], a fork of the New Typesetting System (and more complete TeX implementation than JMathTeX), I added an SVG generator that converts numbers to string using a StackOverflow answer[3], instead of using Ryu[4]. The performance was even better and the algorithm vastly simpler.
Knuth was right: measure, then optimize.
