lineiform VS glicol

Sounds similar to lineiform. Which isn't all that stable or actively developed, but it is a cute approach to writing a meta-jit in rust. It's a weird approach, but IMO it's worth more experimentation.

Working on Lineiform, my meta-JIT library, some more.

In response to Cranelift, switching to my own Tangle IR won't be using Cranelift at all (it uses raw dynasm-rs for emitting instructions). I go into a bit in https://github.com/chc4/lineiform/issues/19, but Cranelift specifically has some rules about iflags, the type they use to conceptualize processor flags effects (e.g. add's carryout or overflow). You can only have one iflags value live at a time, and it can't overlap with any other math operation. This is a problem because the x86 we're lifting doesn't always follow that rule, so if we just emit Cranelift as we go it will panic and say we built an invalid function.

I go into a bit in https://github.com/chc4/lineiform/issues/19, but it's less a problem with its optimizer and more a problem with its IR constraints. Cranelift specifically has some rules about `iflags`, the type they use to conceptualize processor flags effects (e.g. add's carryout or overflow). You can only have one `iflags` value live at a time, and it can't overlap with any other math operation. This is a problem because the x86 we're lifting doesn't always follow that rule, so if we just emit Cranelift as we go it will panic and say we built an invalid function.

The iflags design in general is kinda awkward too, and was being rethought a few months ago when I was first getting this working; I think they're planning on redesigning the add carryout interface and things to be slightly more streamlined. I suspect that any redesigned interface will have similar problems with mismatch between what I want from Cranelift and what 90% of other uses of Cranelfit want, though, and so I decided to just make my own IR instead.

Working on the codegen backend for Lineiform again. I sketched out a plan on how to implement register allocation in a way that hopefully doesn't have horrible behavior in the majority of cases, and implemented ~half of it last week, and hopefully I'll implement the other half and instruction scheduling this week.

Yup, https://github.com/chc4/lineiform. It's not usable at all yet - I was building it on top of Cranelift, which turned out to be a fairly bad idea, so I'm going to have to essentially rewrite all of it with my own codegen backend I think. I've been hacking on it on and off but it's been much slower progress due to work (and writing a codegen backend is hard...)

I got struck by either a very dumb or very good idea a few days ago, and finally have a working (minimal) proof-of-concept for it: Lineiform is a meta-JIT library to nearly automatically get an optimizing method JIT from a Rust interpreter. It does dynamic recompilation on closures by lifting from x86 to Cranelift IR for runtime function inlining and constant propagation.

I've worked on Ambient Engine and now on the Bevy engine. I totally agree with these points, very valuable. I only make some comments from my professional (audio) perspective:

We need the highlight author's affirmation of cli. Rust's tui (ratatui) is great. I used it to make Glicol-cli [1]. If you are a Linux user, you are welcome to test the music production of the code.

Speaking of game audio, I actually think rust is perfect for audio. I have also continued to develop Glicol recently, and my recent goal (starting tomorrow) is the bevy_glicol plug-in. I want to solve bevy's audio problem on the browser.

All in all, even though I've had my share of pain with ecs, I still think rust is very valuable for game and app development, maybe not multiplayer AAA, maybe practical apps.

Nice! Great project website styling and demo.

I had a WebGPU scope demo using vanila JS here, but it's not connected to AudioContext at all.

Still, I had to use the old WebGL solution for https://glicol.org since the WebGPU support seems to be pretty slow at the moment.

Suno is great and I already shared its potential back in v2. I have always believed that the essence of digital music is "organized numbers". I think what needs to be thought about is how to use AI in this process. If you look at the results (numbers) generated, then we are indeed very close. But there is another future I believe: I hope AI can compose music with me, like copilot. This is why I keep working on

Also want to hear your feedback.

Interesting!

Similar note-based expression can be found on TidalCycles/Strudel. although it's not valid MIDI format anymore, you can use notation like c4, f3, and make them as "pattern". Samples are also supported in the same manner:

And in my project Glicol, I use only numbers in the seq node. So 60 means middle C. Underscore means rest.

I also applied with Glicol (https://glicol.org/) and got rejected, which is totally understandable. I am basically working this project on my own with almost zero extra funding.

I am currently working on a new website. The old stack is Vite, Svelte and Windi CSS (discontinued unfortunately). So this time maybe Astro + Solid + Tailwind.

And I am also trying to rewrite the whole Rust backend if possible, so there is quite some work to be done.

Let me know on GH or Discord if you are interested.

It's a good chance to try Rust, WASM, DSP, etc.

This is a really informative and inspiring article.

It hasn’t been 6 months (not 6 years) since I quit my full-time job as a Rust developer to start my own business.

As time goes by, I can feel the pressure of mortgage and car loans, and I can also feel the care and pressure of my family.

My original plan was to make an interface for Glicol (https://glicol.org), and to develop relevant hardware with firmware written in rust for school education.

I sent some cold emails to VCs, but most of them got no reply.

I also sent an email to the Norwegian Museum of Science and Technology, offering to perform for children for free, but they didn’t reply for two months. I shamelessly sent it again, and someone finally replied with a rejection.

Only one VC talked to me and thought that I should convince and validate a partner first, and he suggested that I go to an incubator.

Very good advice.

Later I learned that even Norwegian education startups skipped Norway and focused directly on the US market.

People from the incubator also told me that it is impossible for Norwegian schools to accept new things independently.

This is very enlightening to me because most of Glicol's visitors are indeed from the US. And it took me so long to discover this fact.

But if I don’t start, I’ll never get past those six months.

I picked up LOGO when I was 6 and leant Pascal and C later.

I didn't program for a few years because I wasn't interested in competitions. So I think interest is the most important, otherwise it will be easy to get lost and give up.

Later, I became very interested in programming, mainly because I came into contact with music technology.

I think since your child is interested in game development, it is a good choice to start step by step. For example, starting with threejs. I also recommend learning Rust and Bevy so you learn the underlying layers and ECS.

Last but not least, although it's not related to games dev but I sincerely invite you and your son to try Glicol (https://glicol.org), the project that I am developing.

I quite my job as well to work on

https://glicol.org

I have a lot of feelings, but I don't have a blog so far. But one of my feelings is that universities should alloc some of their funding to many of these open source projects and open source community should be better managed rather than donation. My plan is to start my own company and work on hardware .
