Pretty wild to me that AI has enabled the commoditization of one of the gnarliest engineering problems. Over the course of just a month, we now have three "viable" AI-driven iteration-focused Rust compilers: - https://github.com/makepad/relax - https://github.com/DioxusLabs/rustd/ - https://github.com/indexable-inc/blaze

Somehow always, someone somewhere rediscovers that cutting down the time between coding and code execution makes our lives easier and to a degree be able to write better programs.

Perhaps the earliest and best attempt was Lisp's computational model. Since then, the idea manifested itself again[1], again[2], and again[3] in different forms.

I built something similar - tbd on maintaining it - but I got Rust Analyzer emitting code and as well as running in the web. This new concept of rust compile daemon is pretty sick.

Can build and iterate on Rust in the browser!

Rust is a nice language but it’s so heavy. Since our company switched from Go I’ve had to become used to my laptop being burning hot and stuttering whilst trying to do anything during compilation.

We have had good experience with kache so far to speedup builds in CI and local

Anyone know what effect it has on targets/ bloat and dev disk usage?

I've been using "mr boxington" (mbx) the past several weeks and it's been a big help. https://mr-boxington.jdx.dev/

> 0 crates.io dependencies, in 438k lines of Rust

It's great to have zero deps, but that's a lot of code to maintain.

I knew that makepad devs were focused on build times, but didn't imagine this much!

This is preposterously ambitious - a complete Rust re-implementation. Looks like it's mostly claude?

The world really needs something like this, but why such a slop UI website.

Just tell Opus 5.5 to "redesign the UI to not look like AI slop, design it like a human expert designer would" at bare minimum.

Common Lisp lurks in the shadows, watching its own reinvention comfortably, yet another time

moving errors from compile time to runtime is good?
