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.

Is it possible to have a superset of the C programming languages standard that is as safe as Rust?
There is this: https://github.com/zetzit/zz

ISO C became unusable for operating systems development
You're right that you can't define a safe subset of C without making it practical. MISRA C defines a C subset intended to help avoid C's footguns, but it still isn't actually a safe language. There are alternative approaches though:
1. Compile a safe language to C (whether a new language or an existing one)
2. Formal analysis of C, or of some practical subset of C, to prove the absence of undefined behaviour
Work has been done on both approaches.
ZZ compiles to C. [0] Dafny can compile to C++, but it seems that's not its primary target. [1][2]
There are several projects on formal analysis of C. [3][4][5][6]

Foundations of Dawn: The Untyped Concatenative Calculus
Formal methods have been used successfully for decades; it's not just a pipe dream. Perfect software should ideally be something like ultra-low-defect software, though (that's the term the AdaCore folks use).
There are also other projects that aim to make formal software development much easier [0][1] and of course there's SPARK Ada.

Programming in Z3 by learning to think like a compiler
This post reminds me that I've been wanting to try out ZetZ[0]. It incorporates Z3 into a high-level programming language, and seems to do a lot of what the post talks about automatically.

Grids in Rust, part 2: const generics
I still want to try the ZZ language (https://github.com/zetzit/zz) someday. It compiles to C, and uses a SMT solver to prove that you don't index out-of-bounds at compile time. But I don't like how it lacks generics, uses C idioms, and compiles to C.
-
Another technique to manage memory
The zz language uses a SMT solver to check for program soundness... I haven't tried it, but that's got to be more flexible and resource-hungry.
-
We are building a new systems programming language
Especially the fact that it outputs C code. So interop is seamless.
https://github.com/zetzit/zz
For any systems language, interop with C is the litmus test.
With that in mind, this new language should not require 15,000 lines of standard library. A type-safe wrapper for libc should be enough...
-
Does such a language already exist ("Rust--")?
You might find ZetZ interesting!

Ask HN: Looking for statically typed, No-GC and compiled Lisp/scheme
Looking for a personal project so open-source would be great, but maturity/production readiness is not really a factor.
The only significant thing i can find so far is https://github.com/carp-lang/Carp.
Anything notable that i might have missed ?

Lisp in Space
Not CL, but there is ulisp (http://www.ulisp.com/) for microcontrollers, supposed to be really tiny, and there is Carp (https://github.com/carp-lang/Carp) which is without a GC so seems suitable for real-time stuff.

Yet nobody questions ABAP, Lua, Julia, Groovy or Scala, both of them are under Lisp in TIOBE Index

Emerging Rust GUI libraries in a WASM world
Everybody is trying to make a more user-friendly Rust. The problem is that it is not clear yet whether that's possible, and if it is, how it may look. I know Vale and have tried it, though it's extremely early to judge anything so far. It does have a much stronger theoretical background than V, but even the theory is not completely clear at this point.
There is also Carp by the way: https://github.com/carp-lang/Carp

checkedc - Checked C is an extension to C that lets programmers write C code that is guaranteed by the compiler to be type-safe. The goal is to let people easily make their existing C code type-safe and eliminate entire classes of errors. Checked C does not address use-after-free errors. This repo has a wiki for Checked C, sample code, the specification, and test code.
