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.

picoCTF 2021 -Mind your Ps and Qs writeup-
Normally, it is better to implement the RSA cryptosystem and solve the problem, but in actual CTF, it is necessary to solve the problem as fast as possible, and in this article, we will use RsaCtfTool(https://github.com/Ganapati/RsaCtfTool ), which can solve the RSA cryptosystem quickly in CTF. In this article, we will use RsaCtfTool, which can solve RSA cryptosystem quickly by CTF. It is very simple to use, just give c, n, and e as optional arguments, and the plaintext will be returned.

YouTube: Google has found a way to break Invidious
A parameter was changed from '2AMBCgIQBg' to 'CgIIAdgDAQ%3D%3D' which is just the correct base64 encoding they should have been using the entire time.
I don't think this was a hostile action by Google, I think someone just added better input validation for security reasons and it accidently broke the bad requests they were sending.

PicoCTF 2024- CanYouSee
❗This is indeed the flag, but the text is encrypted with Base64. Usually, the presence of padding character "=" indicates that's Base64 type of encoding (but that's only one of the hints). To decrypt it, we can use CyberChef. Copy-paste the text and we either:

CyberChef from GCHQ: The Cyber Swiss Army Knife
It uses a combination of magic bytes (like the `file` command), entropy analysis and character frequency detection to determine whether an output is likely to be of interest to the user.
The file type mechanism is written here[0]. There's a list of all signatures we detect here[1].
