IBM 5100 appears in Stein's Gate... We probably have some Star trek and some Asimov there in that infamous mix.

I can confirm. The author was an Intel engineer who was dissatisfied with how his senior engineers did the DOS EXE format in the intro of the docs of his assembler. A86/D86 where fantastic, with extra bonus points for the docs.

Technically, that's a bit off topic because this is about compilers and code generation, while a VM defines the basic semantics compilers work with. For VMs, what is relevant is whether you implement an "inc (reg)" or not, th

Actually, what I saw on comp.lang.forth the last few times I checked it (coincidentally, I tried yesterday) makes the news not really surprising. Aside from the spam, it gradually switched from passionate but respectful debates to name call

I believe this is because of Liskov's substitution principle (LSP), which is the hidden gotcha that awaits around the corner beyond the "manager is-a person" [1] example. The "square is-a rectangle... or maybe not"

You mean 64 bits pointers and 32 bits integers, I guess.

To be clear, I don't think this function is spaghetti code. I believe you are victim of premature optimization. You knew Forth would be slow because interpreted, so you feared for performance. Fear often makes you do the wrong things.

I'm not sure if it's intentional or not, but the 'D' usually stands for Doubt (sometimes Deception).

Oh, I see. I was wondering how an argument parsing library could be as big as a bytecode interpreter like Lua.

The Forth situation is a little bit different: it is a language designed to be easily to implement, so everyone is redoing Forth all the time, including its own creator (Cf. Colorforth) who said that "Forth is what Forth programmers

Not in France, as far as I know - or I'd be curious to know in which region it is used like this. "Euh" is typically the equivalent of "erm"; it signals hesitation [1]. It can also be uttered when a person is surpri
