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.

Exploring x86-64 Instruction Encoding
You can visualize how instructions are encoded with zydisinfo. Pass in your architecture and the hex bytes of the instructions and it’ll show all relevant info

Resources on building a disassembler/debugger(like gdb/IDA but better) in C ?
Start with a disassembler. Your first job is to parse out the binary format (ELF/PE/Mach-O) and get the raw bytes representing the machine code from the text section. You need to parse and decode them into actual instructions, and a disassembly framework like capstone or zydis or countless others can help interpret the bytes. At this point you now have a basic linear disassembly view (similar to objdump) of your compiled executable, and can continue to add features, like visualizing control flow, identifying functions, resolving strings and imports from the other sections, etc.
