Teaching Rust in 5 days :ferris:

https://mo8it.com/blog/teaching-rust/

A blog post about my experience teaching #Rust at my university 🎓

Highlight from the summary:

"If students without much experience (some of them had only one lecture about Python) can learn the basics in 5 days, then I think that developers should stop calling Rust complicated"

I am starting a Mastodon campaign :omya_mastodon:

Every time I see a post with only the #Rust tag, I will kindly ask the poster to use #RustLang instead 😇

My feed is full with unrelated content about the film, the game and of course photography of rusty metal 🤬

I will also only post using the #RustLang tag starting from now 😤

You can join me! 🤗

The goal is to let the usage of the #Rust tag vanish so people can only follow #RustLang 😃

I see many people using #Codeberg or self-hosted #Forgejo for #AdventOfCode and I love that 😍

Codeberg is booming, at least for personal projects 🚀

It is so "ironic" that Github, the leading platform for open source software, is proprietary… #FOSS gotta wake up one day!

I think that the planned federation will bring more collaborative projects over 🏃
Think of Mastodon for Git 🤩

Now that the #Serde issue is resolved by removing the binary, I want to thank @decathorpe again, not only for reporting the issue, but also for all his efforts in the #Rust and #Fedora communities ❤

For others: Please don't call things like this "drama" again. This is pushing back against mistakes that would affect the whole community. I love how much the community cares and that such problems are not ignored 🥰

We are not here to only get things done, we are building a future ❤

#OxiTraffic, a self-hosted, simple and privacy respecting website traffic tracker 🌐

➡️ Demo: https://oxitraffic.mo8it.com

I just published version 0.6 with a #Docker image! 📦️
(You don't have to use Docker though)

Do you have a #blog?
I can host it for you if you want to test it with your website :blobcatheart:

Of course, it is written in #Rust 🦀
Check out the README, I spent a lot of time on it 😇

Boost? 🔃🥰

I joined the Codeberg e.V. to support #Codeberg :blobcatheart: (only financially for now)

You can do so too and support maintaining a free (as in freedom) code collaboration platform:

No more code stealing to improve a proprietary AI! #FOSS needs a better home 🏠️

New #HelixEditor release 🎉

https://helix-editor.com/news/release-24-03-highlights/

Helix is a modal terminal editor with an awesome out-of-the-box experience 🤩

Release highlights:

• Jumping
• Block comments
• Improvements to tree-sitter injections

It is also the first release with tiny contributions by me 😇 (since it is written in #RustLang 🦀)

Finally, the video with the powerful quote by Google is uploaded!

"Rust teams at Google are as productive as ones using Go, and more than twice as productive as teams using C++" 🤯

https://youtu.be/QrrH2lcl9ew

Rust isn't just about memory safety, Rust isn't just about performance, Rust is also about productivity, reliability and correctness!

I found the video to send to people when I want to convince them of Rust 🦀

Typical "before vs after diving into #Rust" experience 😂

It was my experience too 🙃

A rant on my tiny talk about #RustLang vs #JuliaLang in scientific computing.

The same person commented again some days later saying that they love Rust now 😅

Give Rust a serious try by starting with the Rust book before judging 😇

Faster Rust Serialization 🚀

https://mo8it.com/blog/faster-rust-serialization

A blog post about avoiding allocations and improving the performance of serialization in #Rust!

It doesn't only apply to JSON, but to any #serde serializer.

The example in the blog post shows a speedup of up to 2.25x 🤯

Feedback welcome :blobcatheart:

I am following this fantastic #XPBD tutorial in #Bevy by @johanhelsing and I highly recommend it after learning some of the basics of Bevy 😍

https://johanhelsing.studio/posts/bevy-xpbd/

The tutorial isn't complete yet, but the first 6 parts are already a lot of material!

The attached GIF is the result of the first part ✨

@johanhelsing thank you for this treasure 🥰

PS: I know there is the physics library bevy_xpbd, but I want to implement XPBD from scratch for learning :D

Progress with my physics from scratch in #Bevy 😇

I was asked to simulate one sphere and plot its energy to validate my physics implementation.
But since I use #Rust, I thought why not simulate 10000 spheres instead? 😂

I don't understand the energy spike at the beginning, but at least the energy is stable later.

#XPBD #RustLang #egui

A grid of 100x100 spheres bouncing on the ground without friction. A plot shows the potential, kinetic and total energy. The system gains some energy at the beginning, but oscillates then around 1.3x of the initial energy. At least it is stable.

I am very excited to announce that I am now one of the maintainers of #Rustlings 🦀

Thanks to the maintainer Liv (shadows-withal) for trusting me 🥰

I have two big ideas ✨

1. Easier installation with Cargo
   https://github.com/rust-lang/rustlings/issues/1919

2. Making Rustlings a TUI using Ratatui
   https://github.com/rust-lang/rustlings/issues/1920

You are welcome to give feedback on these ideas 😃 (But they are not planned until Liv approves them)

If you have any other ideas for improving Rustlings, I am waiting for your repo issue 🤗

#Rust performance tip 🚀

If you want to update the value of a String, it is more efficient to recycle the existing allocation with clear and write* instead of reallocating with format! ♻️

#Divan shows that the method with format! has one allocation while the other one doesn't 😃

#RustLang

Divan output:

I am so proud of my physics from scratch in #Bevy 🤩

It is SDF (signed distance function) collision handling (without a physics engine/crate).

It is obviously not working well. I am just getting familiar with Bevy and implementing physics from scratch for my master's thesis 😇

#RustLang #Rust

Two nails reacting to a collision while one is moved. The left nail is fixed during collision handling, an approximation for infinite mass. The right nail is translated and rotated as a reaction to a collision.

#Rustlings v6 beta is here! 🤩🎉

Russtlings is an official Rust project offering a set of interactive exercises to practice #RustLang 🦀

I have been working on the rewrite for about a month 😇
Now I hope to find some people willing to test the beta release and provide some feedback 🥰

You want to test it? 😃 Here are the instructions:

Announcing axum-ctx: Axum error handling library inspired by anyhow :ferris:

Documentation with examples 📚️
https://docs.rs/axum-ctx

The first screenshot shows the code without axum-ctx, the second one with it ✨

It lets you write concise "one-liners". Any chaining fans here? ⛓️🤩

I will write a blog post about it. But first, I would like to get some feedback here 🥰

C++ will be taken over by #Rust.

What will be the Rust-equivalent for #JavaScript?

I mean #TypeScript is a very good first step, but it's basically the C++ for C.

So in short:
C => C++
JavaScript ≈> TypeScript
C++ => #RustLang
JavaScript => ???

I think it will be a looong way to go, but maybe, maybe we'll see more and more #WebAssembly in the #frontend, but not quite sure yet.

"Quick" Question: If you would build a new #web #application, what would currently be "the best" development language and/or #framework (#webframework) for that?

"Best" as in reliable, #secure, easy to get personal and future proof?

Would it be #python with #django or #rubyonrails or #php #symfony or something completely different?
