howto-wasm-minimal VS v86

I'm particularly curious on what parts cheerp adds to their clang+llvm base. Presumably it's something like the C standard target library for WASM/JS?

For reference, here's examples of what you could do with the baseline clang with wasm (but not JS?) [1] [2] [3], referenced from a similar thread on HN.

[3] https://github.com/PetterS/clang-wasm

For future readers, this is the code that is being referred:

https://github.com/ern0/howto-wasm-minimal/blob/master/inc.c...

It should be:

   uint32_t gray = 0.299 * ptr[i] + 0.587 * ptr[i+1] + 0.114 * ptr[i+2];

This uses a strange "link broker", the link behind this is pointing to https://github.com/ern0/howto-wasm-minimal

> As a thought experiment, we're almost there! We could technically have `win95.img + bochs86vm.wasm + autorun.inf + msword.exe` wrapped in a "browser evaluator"

I looked into this and... holy crap! We are there. Not for modern programs quite yet, sure, but this is amazing. You can use Windows 2000 from your browser.

I think you are looking for Shadow.

Or just the whole kitchen sink. Why not?

Also: https://github.com/copy/v86 - more productized browser x86 runtime, used by eg https://github.com/snaplet/postgres-wasm

Wonder if you could put all those databases in a Linux image and boot it using v86 [0], eliminating the need for a server.

Trying it out in https://copy.sh/v86/?profile=kolibrios , it's also clearly a love letter to Windows 95 in particular. That could be an unstated goal here, create a very particular PC experience under very particular constraints. I don't know anything about the creator but it's very possible that this kind of work was actually their career in the 90s.

It's incredible how much work was done. Maybe this should be an internet curiosity like how TempleOS has become, though Terry's personality was a unique factor.

hmm, why would people still use VMWare? Isn't vbox open source, or even things such as https://copy.sh/v86/ would do most virtualization trick now days?

Oh, there are more OSes one can use at the parent page:

My highlights:

- First version of Windows (1.01)

- SerenityOS <3

- and even ReactOS
