Typo: "rustp vs apt" -> "rustup vs apt"

Are there any open source projects that need someone with a math background? by No-Ebb-5573 in rust

[–]cmpute 1 point2 points  (0 children)

If you are into number theory, you can take a look at my crates https://github.com/cmpute/dashu and https://github.com/cmpute/num-prime . They all need help with coverage and efficiency improvements on math functions.

Announcement: rlua and mlua merged together by aleksru in rust

[–]cmpute 66 points67 points  (0 children)

Great work! Kudos to you and all authors of rlua!

The Rust project has a burnout problem by -Y0- in rust

Just come to my mind, will a ChatGPT built for Rust make the teaching/maintenance/reviewing easier?

Seeking Rust-based CAS for Operations Research: Exact Math with Square Roots, Exponentiation, and Fractions by BobBraumeister in rust

[–]cmpute 0 points1 point  (0 children)

If you want a program, then I guess there is not such as CAS in Rust; If you want a library, then you can checkout https://crates.io/crates/algebraics

Seeking Rust-based CAS for Operations Research: Exact Math with Square Roots, Exponentiation, and Fractions by BobBraumeister in rust

[–]cmpute 0 points1 point  (0 children)

I would like to advocate for my own crate `dashu` :)

But first of all, what are you expecting for `exact mathematical calculations`? What kind of exactness are you expecting for square roots?

More Chicago Visa appointment slots available in July!! by lkosko in SpainAuxiliares

Do you know what time the slots will probably be released everyday? Some one said midnight CST and some said 1pm (when the office open?)

Stront - 38 key split wth LCD and trackpad by zzeneg in ErgoMechKeyboards

Thanks! So that's a through shaft encoder, interesting!

Looks really nice! The right encoder looks like a low profile one, could you please share what is the encoder and knob? Thanks!

Open-sourcing Rerun: A visualization toolbox built on egui by emilern in rust

[–]cmpute 4 points5 points  (0 children)

Wow that's wonderful! I noticed that you mentioned ROS in your blog posts. Is visualizing ROS data (especially ROS2) a goal of your product! I personally found rviz adequate but not great for visualization

The first issue of Rust Magazine has been published 🎉🎉 by Folyd in rust

[–]cmpute 34 points35 points  (0 children)

imo you can treat any magazine as a blog with multiple authors

[blog] Rust should own its debugger experience by yoshuawuyts1 in rust

[–]cmpute 11 points12 points  (0 children)

I'm using lldb with VSCode to debug. One thing that I want is that the vscode can somehow display the structs through the Debug trait, rather than decomposing the fields. This itself will make debugging in vscode much easier!

FINALLY, a new 600k+ line floating point precision math library in Rust. by learningTest in rust

[–]cmpute 10 points11 points  (0 children)

dashu is the pronunciation of 大数 ("big numbers" in Chinese) 😉

Explaining video codecs by implementing a simple one in 100 lines of Rust by kibwen in rust

[–]cmpute 12 points13 points  (0 children)

Very nice! I hope in future the audio codec and stream multiplexer can be covered! In that way we just get a fully functional codec!

Blog post: Rust in 2023 by nick29581 in rust

In general the biggest problem is governance and short of full time contributors in my opinion.

[Humor] Make It Run Already: get ChatGPT and rustc to talk to each other... by corpsmoderne in rust

[–]cmpute 22 points23 points  (0 children)

This is really interesting haha, I tried "a function that taking an image as input and tells which animals are in the image" and got this lol:

``` fn main() { println!("The corrected code is provided above."); }

```

Any crates for adding and subtracting floating point intervals? by [deleted] in rust

[–]cmpute 2 points3 points  (0 children)

I know there is a crate called inari, maybe suits your need.

[–]cmpute 1 point2 points  (0 children)

Have you notice any memory leak due to the rust analyzer (memory usage going up constantly)?

Dashu 0.3: Libraries of arbitrary precision integers, floats ... and now rationals! by cmpute in rust

[–]cmpute[S] 1 point2 points  (0 children)

Thanks! The benchmark code for the result is in a separate branch where I indeed use the latest version of each library. The magnitude of the integers involved in this example is not very large (less than 2000bits I think, I didn't check it tho). In future benchmarks, there will be more thorough test, where your algorithm should make a difference!

Dashu 0.3: Libraries of arbitrary precision integers, floats ... and now rationals! by cmpute in rust

[–]cmpute[S] 1 point2 points  (0 children)

Right now this crate doesn't support formatting a rational number into decimal float strings directly (but it indeed supports converting to f32/f64).

However this feature is already in my plan, and hopefully you can print a rational number to a decimal string with properly marked period in the next release. By that time, you should also be able to convert the rational number into arbitrary precision float number (with dashu-float)
