I was debugging the wrong part of my code for literally days. Checking my vector math and rewriting it a couple of times. I tried multiple new approaches, but things still looked wrong. Then I looked at a part where I did simple stuff: copying data around to the shader.
material.control_point_positions[num_control_points as usize].x = point.position.x; material.control_point_positions[num_control_points as usize].y = point.position.y; material.control_point_positions[num_control_points as usize].x = point.position.z;
Can you spot the mistake?

I should totally rewrite the whole thing to use wgpu, that seems like a great idea, definitely a good idea, nothing bad will come from this, I will build a lot of experience, this is useful
I say as I wonder if an image viewer really needs to use shaders...
Ok so I'm going insane
I've been developing a simple image viewer in Rust, except it can also view animated images like GIFs!
...I feel like the situation has slightly gotten out of hand, I am now for some reason handling multiple threads and learning about Mutexes and other scary things. I am scared please help I am fucking up
#i mean#the only other way I found to create surface to pass to wgpu without using a full blown toolkit is to use the softbuffer crate#and I don't like it#it's alright it's simple but the way you declare types and all is so full of boilerplate#I'm sure writing a whole gpu accelerated shader is so much less boilerplate-y... absolutely

About Me
thought i would make this post because why not
My online pseudonym is Cerulity32K, casually Cerulity. Though, my preferred name is Kali, and my alternate username is Kali the Catgirl.
Though my mental conditions are mild, I do have ADHD (inattentive) and am seeking an autism evaluation. I am also trans (she/they).
But let's get to the good stuff. I excel in computing, especially low-level stuff and graphics (webdev scares me) and math, advanced functions, calculus and linear algebra being the most useful to me. I like to intersect math and computing, and it leads to some pretty fun results, especially when dealing with graphics. My main languages are Rust, C, C++, CUDA, C#, and Python, though I am trying to understand Assembly for a few systems (my laptop [x86_64], NES [6502], and the Atari 2600 [6507]). The main libraries I go to are Raylib and Macroquad for 2D games, and for 3D I go for wgpu, Vulkan, or OpenGL, though wgpu may be the main one I use from now on.
I also do music. My favourite types of music are either loud, distorted songs (FREE.99), literally noise (Portal 2 OST), or electronic-jazz fusion (Creo). I also sometimes make music. It's usually remixes or covers, as I suck at melody crafting, but I have made a couple original songs. I specialize in industrial chiptune and what I like to call "rustcore". My two music environments are LMMS and Furnace, though the latter is the main one I use nowadays.
My favourite game genres are automation, puzzle, and platformer. Factorio, Exapunks, and Celeste are my favourites in those genres respectively.
Other than that, I like to do procedural or subdiv modelling in Blender.
All in all, I'm just a software catgirl :3

Crate of the Week
This week's crate is wgpu, a cross-platform graphics and compute library based on WebGPU.
Despite a lack of suggestions, llogiq is pleased with his choice.
Please submit your suggestions and votes for next week!
Calls for Testing
An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization.
If you are a feature implementer and would like your RFC to appear in this list, add a call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.
No calls for testing were issued this week by Rust, Rust language RFCs or Rustup.*
Let us know if you would like your feature to be tracked as a part of this list.
RFCs
Rust
Rustup
If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

A reminder to never sleep before writing down your ideas!
Ive been writing some wgpu programs in rust and when I went to bed last night I had come up with a great way to fix the architecture of the code and i made the mistake of not writing it down. Now I cant remember what it was T^T

funny that wgpu started checking lifetimes for surfaces using borrowed windows in january and then winit started requiring creation of windows within its event loop in april. it was fun while it lasted ig

This is both a really interesting history of graphics APIs and a nice discussion of WebGPU that makes it sound a lot more interesting than I would have expected.

My 2023 tech stack
For enquiring minds. So I'm a hobbyist game dev, and here's all the stuff I use.
Language - C, clang, make, gdb, lldb
Graphics - SDL2, Raylib
Editor - Neovim, vscode
Graphics - Aseprite
Web dev stack
Hugo, html/css/javascript
I really want to learn more about web assembly and see if there is anyway I could use c or another language to make websites and web apps. And I have an idea for a static site generator project using c and a custom markdown language.
Shit I wanna try
I want to play with rust and wgpu, and Odin. And I want to get better with neovim.

This Week in Rust 596
Hello and welcome to another issue of This Week in Rust! Rust is a programming language empowering everyone to build reliable and efficient software. This is a weekly summary of its progress and community. Want something mentioned? Tag us at @thisweekinrust.bsky.social on Bluesky or @ThisWeekinRust on mastodon.social, or send us a pull request. Want to get involved? We love contributions.
This Week in Rust is openly developed on GitHub and archives can be viewed at this-week-in-rust.org. If you find any errors in this week's issue, please submit a PR.

Crate of the Week
This week's crate is Maycoon, an experimental vello/wGPU-based UI framework.
Thanks to DraftedDev for the self-suggestion!
Please submit your suggestions and votes for next week!
Calls for Testing
An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization.
If you are a feature implementer and would like your RFC to appear in this list, add a call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.
No calls for testing were issued this week by Rust, Rust language RFCs or Rustup.
Let us know if you would like your feature to be tracked as a part of this list.
RFCs
Rust
Rustup
If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.
Call for Participation; projects and speakers
CFP - Projects
Always wanted to contribute to open-source projects but did not know where to start? Every week we highlight some tasks from the Rust community for you to pick and get started!
Some of these tasks may also have mentors available, visit the task page for more information.
If you are a Rust project owner and are looking for contributors, please submit tasks here or through a PR to TWiR or by reaching out on X (formerly Twitter) or Mastodon!
CFP - Events
Are you a new or experienced speaker looking for a place to share something cool? This section highlights events that are being planned and are accepting submissions to join their event as a speaker.
If you are an event organizer hoping to expand the reach of your event, please submit a link to the website through a PR to TWiR or by reaching out on X (formerly Twitter) or Mastodon!

Rust Compiler Performance Triage
Mostly positive week. Most of the improvements come from a revert of a regression from a few weeks ago, but we also get nice wins from re-using Sized fast-path, coming from Sized hierarchy implementation work.
Triage done by @panstromek. Revision range: 15f58c46..8f2819b0
Summary:
(instructions:u) mean range count Regressions ❌
(primary) 1.3% [0.4%, 2.1%] 7 Regressions ❌
(secondary) - - 0 Improvements ✅
(primary) -1.0% [-12.9%, -0.1%] 144 Improvements ✅
(secondary) -2.2% [-12.3%, -0.2%] 111 All ❌✅ (primary) -0.9% [-12.9%, 2.1%] 151
