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.

are there any benchmarks on sector lisp
I'm assuming you are referring to https://github.com/jart/sectorlisp which I gather is an attempt to make a Lisp that fits in a disk boot sector?

I think SIMD was a distraction to our conversation, most code doesn't use it and in the future the length agnostic, flexible vectors; https://github.com/WebAssembly/flexible-vectors/blob/master/... are a better solution. They are a lot like RVV; https://github.com/riscv/riscv-v-spec, research around vector processing is why RISC-V exists in the first place!
I was trying to find the smallest Rust Wasm interpreters I could find, I should have read the source first, I only really use wasmtime, but this one looks very interesting, zero deps, zero unsafe.

I get what you are saying as to be so small that there isn't a place of bugs to hide.
> “There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult.” CAR Hoare
Even a 100 line program can't be guaranteed to be free of bugs. These programs need embedded tests to ensure that the layer below them is functioning as intended. They cannot and should not run open loop. Speaking of 300+ reimplementations, I am sure that RISC-V has already exceeded that. The smallest readable implementation is like 200 lines of code; https://github.com/BrunoLevy/learn-fpga/blob/master/FemtoRV/...
I don't think Wasm suffers from the base extension issue you bring up. It will get larger, but 1.0 has the right algebraic properties to be useful forever. Wasm does require an environment, for archival purposes that environment should be written in Wasm, with api for instantiating more envs passed into the first env. There are two solutions to the Wasm generating and calling Wasm problem. First would be a trampoline, where one returns Wasm from the first Wasm program which is then re-instantiated by the outer env. The other would be to pass in the api to create new Wasm envs over existing memory buffers.
See, https://copy.sh/v86/
MS-DOS, NES or C64 are useful for archival purposes because they are dead, frozen in time along with a large corpus of software. But there is a ton of complexity in implementing those systems with enough fidelity to run software.
Lua, Typed Assembly; https://en.wikipedia.org/wiki/Typed_assembly_language and Sector Lisp; https://github.com/jart/sectorlisp seem to have the right minimalism and compactness for archival purposes. Maybe it is sectorlisp+rv32+wasm.
If there are directions you would like Wasm to go, I really recommend attending the Wasm CG meetings.
https://github.com/WebAssembly/meetings
When it comes to an archival system, I'd like it to be able to run anything from an era, not just specially crafted binaries. I think Wasm meets that goal.

*Laughs in autocmd*
Based on this, the next thing you wrote, and your reference to running a minimal Gentoo: I think you might be a Scheme fan in the making. Scheme is the minimal Lisp. (Okay, that might be sectorlisp which fits in 512 bytes.) It’s hands down my favorite language. While it’s evolved on its own to be more of a superset of Scheme, Racket is my Scheme of choice.

That's pretty much it!

Show HN: Lisp with GC in 436 Bytes
SectorLISP has always had a C implementation for explainability. It started off as ugly C because it was actually used to generate the assembly code for the first ~900 byte version. See https://github.com/jart/sectorlisp/blob/a561e031aec03270459f... and https://github.com/jart/sectorlisp/blob/a561e031aec03270459f... Once we reached 512 bytes I started deleting a lot of the C code since things like assembly macros weren't needed anymore, since the assembly was now being written by hand. https://github.com/jart/sectorlisp/blob/main/lisp.c
Once I cleaned up the C code, I noticed that the entire program didn't use pointers at all! (Except of course to interop with Bestline, but that could be replaced with fgetwc() instead). That's when the idea occurred to me that, since it didn't use pointers, it was also technically valid JavaScript too. So I asked around on Twitter to see if anyone's done a C / JS polyglot before. I got some helpful tips from a code golfer in Estonia who experimented with the idea and he told me about the paragraph separator trick. https://twitter.com/angealbertini/status/1463755612345540611

A completely-from-scratch hobby operating system
Just curious how hard it would be to forego POSIX entirely if you were building an OS. I know TempleOS is entirely from scratch. I'd like to implement a small LISP like SectorLISP [1] (see yesterday's posts too on HN). I don't know much about building my own OS, so I'd like to start with something like MenuetOS (my first PL was asm), SerenityOS, TempleOS, or this one. I'd like it to be completely an 'island', i.e. POSIX not a requirement. I want to use it to hack on in isolation without any easy copy/paste shortcuts. I know Mezzano exists, and it has booted on bare metal, but I would like to start with the OS's above, implement my own LISP, and go from there.
Any other OS recommendations base on my ignorant, but wishful, reqs above? I realize there are some others in Rust too. Thanks!

Interactive GCC (igcc) is a read-eval-print loop (REPL) for C/C++
More recent activity, but based on clang: https://github.com/jupyter-xeus/xeus-cling https://github.com/root-project/cling
Similar to Cling[1] from ROOT.

It's 2023, so of course I'm learning Common Lisp
> The repl driven workflow is amazing and the lisp images are rock solid and highly performant.
do people not realize that basically everything vm/interpreted language has a repl these days?
https://www.digitalocean.com/community/tutorials/java-repl-j...
https://github.com/waf/CSharpRepl
https://pub.dev/packages/interactive
not to mention ruby, python, php, lua
hell even c++ has a janky repl https://github.com/root-project/cling

dont want online ones
Want to see your mind blown? Check out cling, a (sort of) C and C++ interpreter (it's a REPL). Or the work in progress, live-developed clauf, a real C interpreter.

Interpreter vs Compiler
"Exclusively" may be a tough claim. C++ has the Cling interpreter, for example. You could say that "most C++ implementations are compilers". My understanding with Python is that it is challenging to write a compiler for because it's a "dynamic" language. For example, it's possible to create a new datatype at runtime, or even to build strings and tell the interpreter to execute them as source code.

Getting information about classes, methods and variables in C++?
cling(https://github.com/root-project/cling) a c++ interpreter may help, or you can use an IDE or https://en.cppreference.com/ (on duckduckgo you can search directly on it with the !cpp bang, or use firefox 'add a keyword for this search' feature which is really great)

Wisp: A light Lisp written in C++
It has been done several times, at least.

https://github.com/root-project/cling
https://www.softintegration.com
You can argue whether some of those are strictly interpreters, versus just a REPL hooked up to a compiler (as in the case of Cling). But they do exist.
What are some alternatives?
