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.

Ask HN: What interesting problems are you working on? ( 2022 Edition)
It is more like the X Y Z W. However, the X Y Z W bits I am working on as well (https://github.com/TimothyStiles/poly , https://github.com/TimothyStiles/allbase , trilo.bio, freegenes.org). Going for fully automated "make bacterium X produce molecule Y", but still a while away (but surprisingly not THAT far off)

International domain names: where does HTTPS://meßagefactory.ca lead you?
In programming languages it's much worse. Identifiers can either be unidentifiable, and if so everybody has a different opinion what "identifiable" means. Even the standard on identifiers, UTF-39, is buggy and has too many interpretations, leading to a complete disaster. https://github.com/rurban/libu8ident/blob/master/doc/c11.md
In punycode domain names it's quite simple still.
With other names, it's even worse. No-one cares. Linkers do not, username and filesystem drivers do not. The Apple HFS+ did care a bit one day, until someone in the higher ranks decided that no-one needs unicode security anymore and switched the new APFS to unsafe again.

Using Unicode in a compiler
No, it's definitely not safe to use unrestricted Unicode in a compiler. See https://github.com/rurban/libu8ident/ for identifier rules, and http://www.unicode.org/reports/tr55/ for much worse problems.

How can you be fooled by the U+202E trick?
That's why unicode published the security guidelines and mechanisms to avoid such attacks. In 2004 already.
The problem is that nobody cared. Browsers invented punycode instead of following tr39, email ditto. But ok, at least something. Java did it, cperl did, rust did it.
Everybody else is vulnerable. Esp. most other programming languages, filesystems and login systems. https://github.com/rurban/libu8ident/blob/master/doc/c11.md

Unicode Normalization Forms: When ö = ö
I'm maintaining such a library.
coreutils, diff, grep, patch, sed and friends all cannot find Unicode strings, they have no string support. They can only mimic filesystems, finding binary garbage. Strings are so rthi g different than pure ASCII or BINARY garbage. Strings have an encoding and are Unicode.
Filesystems are even worse because they need to treat filenames as identifiers, but do not. Nobody cares about TR31, TR39, TR36 and so on.
Here is an overview of the sad state of Unicode unsafeties in programming languages: https://github.com/rurban/libu8ident/blob/master/c11.md
