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.

I learned to program the Commodore 64 in basic and compiled C
Yeah, it’s better to use a “high-level” language designed for the architecture, such as this: https://github.com/dschmenk/PLASMA

A Java Virtual Machine for the 6502
The developer would abandon this due to the inadequacies of the 6502 to handle a language like Java. He didn't give up though!
> PLASMA is a combination of operating environment, virtual machine, and assembler/compiler matched closely to the 6502 architecture. It is an attempt to satisfy a few challenges surrounding code size, efficient execution, small runtime and flexible code location. By architecting a unique bytecode that maps nearly one-to-one to the higher-level representation, the compiler can be very simple and execute quickly on the Apple II for a self-hosted environment. A modular approach provides for incremental development and code reuse. The syntax of the language is heavily influenced by assembly, Pascal, and C.

The Apple Event logo looks pretty good in mono High Res (HGR) as well!
In my 40+ years of doing graphics programming I've never heard the term color attribute used to describe the high bit / pixel shift. But then again I don't do a lot of reading W.R.T Apple 2 graphics due to personal experience of just using it. =P

Pixel editor software?
Another bare-bones alternative is my HGR Byte Editor. Includes both HGR and DGHR pixels editors and assembly source.
What are some alternatives?
