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.

Are there any libraries for defining and generating code for byte- or bit- aligned messaging or packet formats?
I had a similar use case for embedded microcontroller work. Unfortunately, the only one that I found that lets you have bit-level control is bitproto. The problem with all these protocol formats is that they require generated sources to be included in your project at compile time.

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.

Ingesting, parsing and making sense of device log data
For binary log format, there's the excellent Kaitai Struct frameworks, that make it very easy to generate parsers from a declarative schema
