No; Bauble doesn't know how to "rasterize" SDFs into meshes; it only knows how to raymarch them. It's theoretically possible, but it's a pretty complex problem that would take me much too long to figure out and impl

Ohhh I totally missed that you're the author of Glicol. Okay. So you integrated Hydra as like a first-class thing -- I see I see. I thought you were plugging two 3rd party things together. So I'm guessing that the best case scenar

Ohhh I think I misunderstood how this works. You write the visualization ahead of time, and then you livecode the music only? Bauble would work well for that -- you could just grab the compiled shader source and integrate it into your livec

Thanks! I'm not really sure how to make it work with Glicol -- I don't know anything about the livecoding world. But in theory it would be easy to add a new "magic variable" (shader uniform) for like "mean root sq

It's CodeMirror! All I had to do was write a Janet grammar for it -- very easy to do. CodeMirror is pretty amazing -- I was able to implement the "edit values with your mouse" by just asking CodeMirror for the syntax node und

libfive is great! And if you're into SDFs, libfive will give you something Bauble probably never will: the ability to export shapes as meshes, so you can 3D print them or import them into Blender or whatever. libfive is only concerned

Okay, this is cute, but by going against design conventions I think you have a landing page that most people will bounce off of. The navigation settings are at the very bottom in the footer area where I normally ignore things like "pri

You know, I discounted Nial prematurely because its array model seemed weird and different and -- still not actually knowing anything about array languages -- I became very enamored with J's ability to slice and reassemble arrays based

I really like Ivy as a simple, friendly introduction to APL. There is a surprising lack of APL-derived languages that use words to name things -- most stick with the original symbols; J and friends choose equally-cryptic symbols composed of

zsh can do this if you set the PATH_DIRS option, but if I remember right it doesn't autocomplete deeply nested directories, just one level. I made a little tool that dispatches hierarchical commands in a slightly nicer way, with intell

I am very interested in this project as a "better awk" is something I have often fantasized about. I read all of the documentation that's available on https://tokay.dev/tokay-docs/ , but unfortunately it

This is a good question without a good answer. zsh-autoquoter doesn't know -- it doesn't know anything, really. The only thing it does is pass the literal string you type as an argument to the command you run (in this case, ssh).

A typical JIT compiler runs in the same process as the executable as part of its runtime -- it's a program modifying itself. This is describing a compiler modifying the memory of a separate running process out from underneath it. Which

Yeah, I think that nix.dev is a much better resource for getting started with Nix quickly. I wrote How to Learn Nix mostly out of curiosity: I was interested in Nix as a concept, and I didn't really know what it could do going into it.

I think there are two distinct arguments against nix-env: 1. Imperative package management is evil 2. The package name-based interface used by nix-env is evil I don't ascribe to (1); I quite like installing things "the old-fashion

Since "How to Learn Nix" mirrors the (bonkers) presentation order from the official documentation, I am afraid to say that you will not learn how to do this until part 32 , deep into the Nixpkgs manual. https://ianth

That’s great! This is only testing about 2% of the packages in Nixpkgs, but I bet if you weighted by package use that number would look a lot more impressive. Good work, maintainers! But I stand by: this is the product of a lot of hard work

Do you mean building something like this software demo, or turning it into a real instrument? In software, honestly the MDN docs for the web audio API is a pretty great starting point. Assumes very little prior knowledge, and goes into a lo
