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.

Six programming languages I’d like to see
The interesting semantic relationships are those that let the machine automatically deduce optimizations
> I also like the idea of modifying function definitions at runtime. I have these visions/nightmares of programs that take other programs as input and then let me run experiments on how the program behaves under certain changes to the source code. I want to write metaprograms dammit
Lotta metaprogramming in Joy. Many functions work by building new functions and running them, it's a natural idiom in Joy.

> A language designed around having first-class GUI support
Red? ( https://www.red-lang.org/ )
> Visual Interface Dialect ... is a dialect of Red, providing the simplest possible way to specify graphic components with their properties, layouts and even event handlers. VID code is compiled at runtime to a tree of faces suitable for displaying.
https://github.com/red/docs/blob/master/en/gui.adoc
> You can’t work with strings, json, sets, or hash maps very well, date manipulation is terrible, you can barely do combinatorics problems, etc etc etc. I want a language that’s terse for everything.
That also sounds like Red.

Beads: The next generation computer language and toolchain
> They are well funded.
Rebol Technologies went bankrupt, and Rebol is de-facto dead since more than a decade; Red barely manages to get by thanks to a recent crypto spike.
> I would say the languages are very different in the sense that Beads is clearly aimed at graphical interactive software.
So is Red with it's native GUI engine. [1]
> They are so different that it is hard to compare.
Both share the same goal of replacing modern software practices with biased, batteries-included toolchain, varying only in implementation.
> Red being a concatenative language has more in common with FORTH than Algol.
Red is not concatenative in any sense of the word, nor any other language in Rebol family that I know of.

One Way to Represent Things
> What if a simpler programming language had first-class representations of a lot more than strings and arrays?
Red lang?
> Where most languages have 6-8 base datatypes, Red has almost 50.

Letlang — Roadblocks and how to overcome them - My programming language targeting Rust
That works for any types (except the functional types), and even the generic ones. During code generation, I create structs that implement the Type trait.

A new milestone for Letlang (targeting Rust) - Effect Handlers
As stated on the website ( https://letlang.dev ), Letlang is a general-purpose language.

Writing a simple Lisp interpreter in Rust
Author here, the article is more about how Rust and its ecosystem are nice tools for language designers rather than the beauty of Lisp.
The crates listed in that article are the ones I use for my compiler: https://letlang.dev
Lisp was only chosen as a way to demonstrate the power of those crates and Rust features. A kind of way of justifying my choices for Letlang.
It's not "you should do it like this" but "you can do it like this".

Ask HN: Possible? Faster than C, simpler than Python, safer than Rust
"Faster than C", I saw people write C code slower than a Python equivalent. So I have to admit, I don't know what it means for a language to be fast, because it depends on the algorithm being implemented.
---
"simpler than Python", what does "simple" mean?
Simple design? Python's design is very complex (take a look at "Crimes with Python's pattern matching" < https://www.hillelwayne.com/post/python-abc/ > for example), on the other hand, assembly languages, or Lisp, or Forth, have a very simple design.
Simple as in "easy to use"? Rust is easy, write code, fix what the compiler tells you you did wrong. Joke aside, Go is quite easy to use and while I personally don't like this language, I get why it replaced Python in a lot of use cases.
Also, once you get used to the OTP framework, Erlang/Elixir/Gleam/any beam language are quite easy to use and have less footguns than Python.
---
"safer than Rust" is too vague. Is it memory safety? type safety? thread safety? cosmic ray safety? A mix of all of that?
Let's guess you meant "memory safety". All languages with a Garbage Collector are "memory safe".
---
On a semi-unrelated note, I've been working on https://letlang.dev
It's a language inspired by Erlang/Elixir (same concurrency model) that compiles to Rust code (the runtime use tokio). It is immutable, have no Garbage Collector thanks to Rust semantics, and dynamically typed.
I haven't run any benchmark (it's not even finished, I've been working on the specification before continuing the implementation), but I guess it could be slower than a rock.

For some recommendations, have you looked at Zig? Nim? Hare?

Syntax for defining algebraic data types
In my language (Letlang), I use the keyword class with structural pattern matching and optionally a predicate. Types (or rather, classes) can be combined with logical operators &, |, !:

Erlang's not about lightweight processes and message passing
Not sure this is what GP is talking about but to implement the actor model in https://letlang.dev I use tokio.

Features you've removed from your lang? Why did you put them in, why did you take them out?
In the early drafts of Letlang, I had the goal to add an equation solver. I got rid of that because:

What features would you want in a new programming language?

Six programming languages I’d like to see
For a contract based language and a "really dynamically typed language", I'm working on https://letlang.dev
And it's because I haven't thought yet about how to do static type checking with such a feature.
I haven't got any time to work on it in the past few weeks, and I'm the only dev (would really love some help). So, it will be ready when it will be ready :P
