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.

2,900 page Manual about Pandas [pdf]
> And what's the alternative, Excel?
Take this with a grain of salt from someone who needs data manipulation occasionally every now and then (as opposed to being a full time number-cruncher, data-scientist, statistician etc.), using krangl[1] for Kotlin has been a great experience.
I was drawn to this library because I use Kotlin in my dayjob for backend development, but I love how well Kotlin's succinct syntax & features like extension functions lends itself to data transformation & ETL kind of use cases.
Also it doesn't hurt that JVM has a plethora of libraries available for things like DB access, plotting, etc.
I am sure that Pandas has many features I am unaware of, and for a lot of people the high-ish startup time can be a deterrant, but for most of my day to day data munging the combination of jbang, krangl & kravis has been a pretty good fit.

Why should I use kotlinx.serialization?
Kotlin multiplatform types often come with their own serializers. https://github.com/Kotlin/kotlinx-datetime and https://github.com/hfhbd/kotlinx-uuid do, for example.

What's the best way to calculate the number of days between two dates in Kotlin?
It depends, time has a complex and native bound legacy. But I bet you want this https://github.com/Kotlin/kotlinx-datetime and DateTimePeriod.
