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.

Cwerg: C-like language that can be implemented in 10kLOC
Perhaps these have already been dealt with and I'm missing critical information. If so, my apologies. Great work, in any case.

Where can I find resources and guides on how to build compiler backends?
Cwerg has backend that can be used as JIT and is written with readability in mind. Additional documentation can be found here: https://github.com/robertmuth/Cwerg/tree/master/Docs
- Most important language features not touched in the book "Crafting Interpreters"?
- Lack of resources in creating Assemblers from scratch.

Minimum ISA Capabilities to Support Most (Non-Interactive) Programs?
I defined a basic ISA-like IR for Cwerg. It has unlimited registers and no constraints on immediates.

Syntax Design
I was also going down the path of bike shedding concrete syntax for my language Cwerg before pulling the plug on that effort and just using s-exprs. I managed to make the s-expr quite succinct by carefully choosing the order of arguments so I can omit optional ones. Also very helpful was to use square brackets for list, e.g. (call fun-name [arg1 arg2]). This simplifies parsing a little bit and is easier on the eye. Here are some Code Examples

November 2022 monthly "What are you working on?" thread
I am iterating over the languages features for Cwerg's Frontend which aims to be a low level language with about the complexity of C but with some of the comforts of modern languages. I am especially happy with the choice of adding sum types. Relative to C the current feature set looks like this: Removed: * arrays decay to pointers * bitfields * separate compilation (more of a backend issue) * pre-processor * varargs * implcit type conversions * (untagged) unions * ++/-- * comma operator * implicitly nullable pointers * goto

Dictu - A simple programming language
Dictu is a high-level dynamically typed, multi-paradigm, interpreted programming language. Dictu draws inspiration from the family of languages surrounding it, such as Python, JavaScript and Lua. It's a language that I have been working on for a few years now with contributions gratefully coming in from developers from all parts of the globe.

April 2021 monthly "What are you working on?" thread
I've been working on Dictu (https://github.com/dictu-lang/Dictu) which is a high-level general purpose language, with inspiration from languages around it such as Python. While working on Dictu, I find it's obviously nice to implement things with the language being created so i made an automatic watering system with the code written in Dictu! While doing so, things like syntax highlighting and whatnot is pretty much a must have, so i've also been wrestling with creating a VSC extension and learning all about LSP!
