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.

Reverse Engineering TikTok's VM Obfuscation (Part 1)
Based on my previous research into this, the magic keywords to find this kind of thing on Google are "virtualization obfuscation" or "VM obfuscation".
rusty-jsyc is the main open source implementation I've found, though it hasn't been touched in a few years: https://jwillbold.com/posts/obfuscation/2019-06-16-the-secre... (GitHub: https://github.com/jwillbold/rusty-jsyc)
I think there are other implementations, but they're proprietary so I didn't look into them very much. There are lots of posts out there about reversing virtualization obfuscation, but not many about implementing it. Seems like most people who put the effort into implementing it tend to prefer selling it commercially (which I suppose makes sense).

Show HN: Obfuscation Tool for Mixed Boolean Arithmetic Expressions
Example of output: https://github.com/seekbytes/pocket#example
Mixed Boolean Arithmetic refers to expressions which include boolean, and arithmetic operations (AND, OR, XOR, PLUS, MINUS, MULTIPLY..). Let an expression be something like A + B. My tool applies some transformations to re-write this expression in more complex terms (such as ((A & B) + (A | B))).
