    Caden Haustein has used the code for Kitten as the starting point for a language called Mlatu, which looks cool. I haven’t been writing about my PL work much, but I’ve still been doing stuff that’s related—although it may end up under a new name, not sure what I want to do with that yet.

    I think SIMD was a distraction to our conversation, most code doesn't use it and in the future the length agnostic, flexible vectors; are a better solution. They are a lot like RVV;, 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.

    The most complete wasm env for small devices is wasm3

    I get what you are saying as to be so small that there isn't a place of bugs to hide.

    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;

    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.


    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; and Sector Lisp; 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.

    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.
