I did a thing: github.com/FractalFir/c... (This is the entire rust compiler, converted to C - yes, it is functional).

I love rust: #rust #rustlang

My Rust Week talk recording is finally available. Very excited to share it with the world :3! www.youtube.com/watch?v=XnU9... Trying to fit all the GPU cursed-ness into 15 minutes was a bit tight, but I made it WORK(I think. I hope. I pray).

You know it is going to be a shit day when `cargo` hangs....

We are excited to announce that we can successfully use Rust's std::thread on the GPU. This has never been done before. www.vectorware.com/blog/threads... Supporting Rust's std::thread enables existing Rust code to work on the GPU and makes GPU programming more ergonomic.

We are excited to announce that we can successfully use Rust's standard library from the GPU. This has never been done before. www.vectorware.com/blog/rust-st... Supporting Rust's standard library enables existing Rust code to work on the GPU and makes GPU programming feel normal.

A cursed C fact of the day: there exists a C compiler out there, for which this assertion will pass: ``` assert(sizeof(float) == sizeof(double)); ``` The Small Device C treats `double` as float: "warning 93: type 'double' not supported assuming 'float'"

I have wrote yet another article about compiling Rust with GCC. fractalfir.github.io/generated_ht... I go over some neat news(running the Rust compiler on M68K CPUs), important topics(eg. how we test `cg_gcc`, or ABI compatiblity), and some fun triva about cursed proc-macros. Hope you enjoy it!

@gankra.bsky.social Thanks to AI overview, I now know that github.com/Gankra/abi-c... sources it's coffee in a sustainable way from Ethiopia. Good to know that my favourite tools are made in an ethical way :)

I implemented the `int_format_into` feature into the Rust `core` library. It allows you to reuse a buffer when converting an integer into a string: ``` let mut buf = NumBuffer::new(); let string_repr = 12u32.format_into(&mut buf); let other_string_repr = 128u32.format_into(&mut buf); ``` 1/2

I have wrote an article about some of my work building the Rust compiler with GCC: fractalfir.github.io/generated_ht... I hope you enjoy :D

Ah, computers never cease to amaze me. For some reason, my "g" key is not working... but it does if I *also* press shift. Meaning I can only type upper-case "G". Thankfully, if i press both caps-lock and shift, they cancel each other out. So, I can still type "g" using 3 keys. I guess it works..

Healthy Data, Rusty Code: Epidemiology Meets Modern Systems Programming by Caroline Morton at RustWeek 2025! www.youtube.com/watch?v=gV55... #rustlang #RustWeek

My talk is in here: www.youtube.com/watch?v=_sv8... Enjoy!

My 2 Rust week talks are out now: youtu.be/4yTZ1PRJ6do?... youtu.be/T-ZUkwNsK-8?... Hope you enjoy them - if you have any questions / comments, feel free to ask! Link to the project the talks are about: github.com/FractalFir/r...

The [GCC compiler backend](github.com/rust-lang/ru...) can now fully bootstrap(build) the Rust compiler! This is my Rust GSoC 2025 project, and you can learn more about my progress here: rust-lang.zulipchat.com#narrow/chann... If you have any questions, feel free to ask me!

Hey look! I've been working on a thing! It's a statically typed, JIT compiled, hot-reloadable, embedded scripting language. blog.nlnetlabs.nl/introducing-...

See how Rust compiler error messages have evolved over time :) kobzol.github.io/rust/rustc/2...

Wrote down some thoughts on how to interpret and use visibility in Rust. kobzol.github.io/rust/2025/04...

Have you ever wondered how panicking in Rust works? My newest article describes the ENTIRE panicking process in great detail! I hope you enjoy it, and have a great day :) fractalfir.github.io/generated_ht... #rust #rustlang #programing #cs

I am giving a talk about compiling Rust to C at Rust Week in May. rustweek.org/talks/michal/ Excited to see all the amazing people there! In the meantime, if you want to know more about the progress I made in the last few months, I wrote an article about that :) fractalfir.github.io/generated_ht...

In the spirit of April Fools, i decided to do something silly. I modified my Rust to C compiler to output Holy C. This allowed me to run a small iterator benchmark on Temple OS - meaning Rust is now one of the 2 languages running on that obscure system. Is this useful? No. Is it real? Yes.

I have been experimenting with realistic renders of 4D space, using ray marching(image attached below, read alt text for an explanation). Usually, visualisations of 4D space use projections or cross-sections of 4D objects. My render shows how 4D light would appear to your 3D eyes. #art #math

I got code written in #rustlang running on a Game Boy :D. While it is not the most useful thing, it is a nice way of showing how compiling Rust to C can allow us to target some old hardware. rustc_codegen_clr(a Rust to C compiler) is still a bit from being fully usable, but it is getting there!
