I've been thinking of doing the exact same thing. Preserve context as images and die. Expose a single tool called "eval". You could have a extremely tight editor integration using something like SLIME.

Still nothing to compete with GPT-OSS-20B for local image with 16 VRAM.

If international law had any effect people would believe in it. You're mixing cause/effect. This situation has been going on for years and the lack of response by international organizations makes people lose all confidence in them.

I'm unfortunately on the same situation. We made a consultation with people from Baptist Health Miami and it seems like there are several non trivial requirements for such treatment (histotripsy), like the number and location of mets. Hope that this improves in the mear future.

One of the first things I tried in Rust a couple of years ago coming from Haskell. Unfortunately it's still not stabilized :(

Yeah, just another data leak, no biggie.

Not at the same level. TRAMP is way behind feature-wise.

> Zig must also be good for eliminating the same ones.

But Zig does not eliminate them, but rather it might catch them at runtime. The difference here is that Rust promises that it will detect them at compile time, long before I ship my code.

> The property of memory safety is itself not binary in both languages

In this case it is: either you catch the issue at compile time, or you don't. This is the same as type safety: just because Python can detect type errors at runtime it does not mean that it's as "type safe" as, for ex. Haskell. This might be due to imprecise usage of terms but that's just the way it's discussed in the craft.

Yes, but instances require the user to provide shrinking while Hypothesis does not: shrinking is derived automatically.

In the sense that you only need to work with the standard IO monad to get the benefits of the runtime.

You don't need "monads" (in plural) since GHC provides a runtime where threads are not 1:1 OS threads but rather are managed at the user level, similar to what you have in Go. You can implement async/await as a library though [1]

> async/await is also available in a bunch of other languages, including F#, C#8, Haskell[...]

Haskell (GHC) does not provide async/await but uses a green thread model.

> Knowing if a function will yield the thread is actually extremely relevant knowledge you want available.

When is this relevant beyond pleasing the compiler/runtime? I work in C# and JS and I could not care less. Give me proper green threads and don't bother with async.

> I mean, Haskell has like what, 2, 3, 4? Major build systems and package repositories? It's a quagmire.

Don't know when was the last time you've used Haskell, but the ecosystem is mainly focused on Cabal as the build tool and Hackage as the official package repository. If you've used Rust:

- rustup -> ghcup - cargo -> cabal - crates.io -> hackage - rustc -> ghc

    } catch (exception: Exception) {
      // log exception
      throw exception
    }

Probably the most harmful snippet ever written. Every blog post about errors has something similar written, regardless of the programming language. Please, don't write, suggest or even pretend that this should exist.

> that data flowing between them consists of simple, agreed-upon formats

Yeah, massive disagree with this. There is absolutely nothing "simple" about these protocols. Try to compose 3/4 UNIX programs together and you necessarily need to run it to see if it even makes sense. Don't get me started on HTTP.

It boils my blood to read "simple" in the context of software engineering

No need to import a third party library: you can use `Data.Function ((&))` for this:

    arg
     & f1
     & f2

How do you deal with persistent sessions in VSCode? I have a remote VM to which I connect through SSH using VSCode, but I need to have certain programs running even after I disconnect from the VM. It's the only reason why I use tmux and I haven't been able to get rid of it.
