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.

Ask HN: Is Lisp Simple?
>Would be interesting to see how the interpreter works actually...
It's quite easy to see, there are interpeters for Lisp in like 20 lines or so.
Here's a good one:

(It has the full code in a link towards the bottom)
There's also this:

Build Your Own Lisp
Here is one implementation of a lisp (mal specifically) in matlab: https://github.com/kanaka/mal/blob/dcf8f4d7b9cf7b858850a04a0...
Only 260 lines of code, pretty concise :)

Found inside my compiler I've been writing for about 2 years
have a look at the crafting interpreters book, plus make a lisp (lisp is a great first language to make a compiler/interpreter for, just google "lisp compiler/interpreter" and you'll find lots of resources)

Crafting Interpreters or Writing an Interpreter in Go? Given context
If you're really okay with the limitations of a tree-walk interpreter, you might want to check out MAL, which will teach you how to write a tree-walk interpreter for a LISP. The code for MAL has been translated to most popular languages, so you can work through the creation of an interpreter in the language of your choice. JLox would give you a bit more detail and a more complex language, but I'm not convinced that it's all that important.

What do I do now?
Write a small programming language (lisp (https://github.com/kanaka/mal) or brainfuck) in C++ to learn the syntax more. This will teach you a lot about programming languages in general.

Can you beat my dad at Scrabble?
So I started some hobbyist game dev using Unity and realised that the full process of making a game has dependencies on a mass of lower-level skills including lighting virtual environments. As a hobbyist photographer I could see some useful analogies from lighting studios and other scenes
So I pivoted, and eventually made money, not from selling a game, but from developing tutorials about digital lighting. I was also able to contribute to a project at work that was making a product based on commercial games engine, not by actually coding it, but by helping to better estimate the costs of the asset generation required.
Coding Unity object scripts in C# also got me back into programming, and I went on to successfully build a self-hosting lisp interpreter following the Make a Lisp guidelines [0].

5-Step Approach: ProjectSveltos Event Framework for Kubernetes Deployment with Cilium Gateway API
The EventSource uses the Lua language to search for any services with ports set to 80 or 443 in the ‘argocd’ namespace. More examples can be found here.

Building a Wordle Clone with Lua! 🕹
If you're new to the 12 in 24 series, I'm learning and building projects with a new programming language every month - this month, it's the Lua scripting language. You can find source code for the projects I build in the official GitHub repository (check it out, this week's folder contains code for both this and two other bonus projects!).

Gearing up for Lua
This month, we're talking about Lua. It's not always a first choice when it comes to programming, but I think there's a lot to enjoy about this little language. Heck, I'm a big game development fan myself - I would look into it even if that was the only reason to.

How do you like code documentation inline in the source code vs. as separate guides, or how would you do it?
I think Lua is a good example of doing documentation well. The source code is commented only as much as needed, mainly with brief comments about things that might not be obvious and a small number of longer explanations of how the architecture works (mainly relevant to developers). It also has a super nice feature that's surprisingly rare: each file has a very short line at the top that describes what the file is, so you don't have to guess based on the filename alone. The API is documented in a single HTML file on the website that has both the high level descriptions of the language and architecture, as well as documentation for each public-facing function. The docs are maintained by hand, but the API is mostly stable, so the docs don't need to change very often.
