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.

Appreciate your insight! After a quick search I found this one https://github.com/RsaCtfTool/RsaCtfTool . Probably gonna give it a try

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.

Parsing an Undocumented File Format
- ImHex [2], which has a pattern language [3] which allows parsing, and it seems more powerful than what Kaitai offers. I stumbled upon some limitations with it but it was still useful.

Hacking the LG Monitor's EDID
An EDID override like this would be helpful for macOS as well, where the monitors swapping around after standby is a real annoyance [0] [1]
EDID rewrites are 99% of the time blocked by the monitor firmware: https://notes.alinpanaitiu.com/Decoding-monitor-EDID-on-macO...
By the way, one helpful tool that helped me navigate the EDID dump was Kaitai Struct [2]. It shows a side by side view with the hex view and the EDID structure, and it highlights the hex values in real time as you navigate the structure. Unfortunately [3] it doesn't support the extension blocks that the author needs.
