New comment by zengid in "One year of Roto, a compiled scripting language for Rust"

I've been thinking a lot about a solution to Rust's notoriously slow compile times. From my research, it's not the borrow checker that is the issue, it's the heavy optimizations and monomorphization, and macro expansion [0]. There are efforts to improve Rust compile times, but I realized recently that it will never be lightning fast, so we (Rust users) should really be developing more scripting languages and DSLs that we can put all of the fiddly bits into.

Places where we would benefit the most from this is in the Games and UI space. I know game devs have already started by integrating lua, like with mlua [1]. In the UI space i think Makepad is the best example of a team making a dedicated DSL that can be hot-reloaded [2].

I think we need more of this! Go make a DSL next time you feel crushed by the weight of compiling Rust crates!

khvzak has compiled some benchmarks. mlua and roto are some of the fastest: https://github.com/khvzak/script-bench-rs

Drew was CEO for almost 20 years right? that's a heck of a run!

Quite a footnote [0]:

> I do not know if it is me being bored with the project, or annoyed with having to build and design a data structure, that has soured me on this project. But I have really at this point lost most motivation to continue this chapter. The way Zig is designed, it makes me deal with the data structure and memory management complexity head on, and it is tiresome. It is not "simpler" than, say, Rust: it just leaves the programmer to deal with the complexity, gaslighting the user claiming it is absolutely necessary.

any tips for running it locally within an agent harness? maybe using pi or opencode?

love to hear good news even if it's a relatively small sample size. anecdotal, but i've heard that the antioxidants in fresh ground coffee is also very good!

not sure why the title was renamed, but i thought this was interesting primarily because it's the early work of Rich Hickey, famous for making the Clojure language.

Heard about this watching Casey Muratori's "The Big OOPs" talk [0]. Thought it couldn't be _that_ Hickey, but turns out it was!

I love C#, I use it every day, but who makes a decision like this?

very beautifully done!

I think it would be cool to have an aeolian harp if you feel up for simulating "wind".

Also since you're going into rhythm and are basing this on JI, a integer ratio polyrhythm system is lots of fun to make!

There is some research in accelerating Reinforcement Learning by implementing the simulator on the GPU using Jax. Really neat. I'm curious if this could be done with Mojo, too?
