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.

Search-and-replace with correct grammatical case - does it exist?
So you want to go from Spende to Spende+genitive to Beitrag+genitive to Beitrags. In addition to Spacy etc. you might look at Finite State Transducers, which I believe are bidirectional, i.e. for both analysis and generation. XFST and SFST and OpenFST are a few of the FST toolkits. See https://github.com/hfst/hfst for the Helsinki FST; there's a German transducer for it at https://sourceforge.net/projects/hfst/files/resources/morphological-transducers/hfst-german-installable.tar.gz/download. I don't think there is much of a learning curve, and there should be plenty of documentation.

Foldable Words
The regex syntax is a bit quirky due to backwards compatibility with lexicons written in XFST, see https://github.com/hfst/hfst/wiki/Regular-Expression-Operato...

A portable, modern regular expression language
The fundamental problem comes from assigning meaning to whitespace (in this case, concatenation). I had the same issues when developing KBNF ( https://github.com/kstenerud/kbnf/blob/master/kbnf.md ) which operates in a closely related space.
In early development, I took a number of cues from regex that turned out to be bad ideas, in particular using whitespace for concatenation (which all BNF dialects seem to do).
Switching to '&' for concatenation fixed it and made things a lot clearer, as it would also do for Pomsky:
'Hello' & ' '+ & ('world' | 'pomsky') -
Ask HN: Please help me by reviewing KBNF
Hi everyone! Merry Christmas and happy new year!
I'm making a modernized BNF-style metalanguage that supports grammars for text and binary formats, but unless there's some kind of outside review, I won't find any blind spots I have until long after release.
If you have experience in grammars or protocols (text or binary), could you take a quick look?
Note: I'm not aiming for perfect expressivity; just 80-90% of use cases without making things overcomplicated so that it can be used descriptively in documentation.

Social media may prevent users from reaping creative rewards of profound boredom
Boredom is what led to pretty much every project I've ever done. I usually have a list in my head of things that could be made better, but they never come to anything until I have a lengthy period of nothing to do.
Latest example: I had to take all my vacation time this year or else I'd lose it. I got so bored that I built this over the past weeks: https://github.com/kstenerud/kbnf
