idel VS ish

There was a wasm predecessor (by, well, me) with a bit more of the Forth flavor: https://github.com/darius/idel

From >20 years ago and my main regret is a failure to carry it through to be more than a demo.

I don't know -- there were at least a couple papers about it, but I haven't been following. At the time it was first announced I used some of the ideas in one of my projects (https://github.com/darius/idel/blob/master/src/opcodes.awk) but unfortunately didn't develop it further.

Thanks, Chris!

Another interesting thing that came out of the object-capability ferment around E and EROS was Darius Bacon's Idel secure virtual machine: https://github.com/darius/idel

Though no other software is as influential as JS, other currently influential ocap systems include Genode, most of the current implementations of L4 (including seL4), and CHERI.

> Just imagine how much more versatile the iPad Pro would be if only you could run Linux VMs on it

After installing https://ish.app for Alpine Linux emulation on iPad, one immediately comes up with use cases, even though it's excruciatingly slow.

Hopefully Apple opens up the imminent M3 iPad Pros to run macOS and Linux VMs.

iSH

They don't "allow" it, but most apps that need background execution just ask permission for geolocation tracking and pretend to use it, for example iSH[1]. There are a few activities that the app can do to prevent itself from being suspended when it goes out of focus, like playing sound, geolocation etc.

Android: install termux, `pkg install openssh`, and preferably run `termux-setup-storage` to give it access to storage folders.

iOS: I think https://ish.app/ ?

This of course hasn't been true for years, eg: http://omz-software.com/pythonista/index.html

And you can run a C compiler (or anything) inside https://ish.app/ too.

False. iSH is an x86 "bytecode" emulator.

"Possibly the most interesting thing I wrote as part of iSH is the JIT. It's not actually a JIT since it doesn't target machine code. Instead it generates an array of pointers to functions called gadgets, and each gadget ends with a tailcall to the next function; like the threaded code technique used by some Forth interpreters."

There is an x86 virtual machkne running Linux available on the App Store now.

Now would Apple allow a full blown Windows VM is a different question

There are plenty of solutions for running Python in an IDE on the iPad. There is an even an x86 emulator and a Linux terminal built on top of it in the App Store.

https://ish.app/

It can run anything that you can run on an x86 in user mode. I downloaded the AWS CLI (which requires Python) to run some tests

By the way, you were completely wrong about VSCode being written in .Net.

> That's just compiling the code to a native binary, which you would then have to go submit through Apple's store. How does that help for an IDE expected to allow you to test (i.e. execute) and debug the code you've just written ten seconds ago?

There is an existence proof that it could be done. If you ran iSH with remote VNC you could have a full IDE on a Mac.
