After years of listening to the Linux Unplugged podcast I had to remove it from my feed today. Their Bitcoin praise just got unbearable. :(

I really like the SwiftUI tutorial videos by Martin Lexow, e.g. this one https://www.youtube.com/watch?v=H_HfEr9DcbY
I really like the SwiftUI tutorial videos by Martin Lexow, e.g. this one. He doesn't waste much time and just shows what SwiftUI is capable of and how to work with it.

„Nun sag doch etwas“ https://hmbl.blog/28-2-2028-nun-sag-doch-etwas/
„Nun sag doch etwas“. Tidbit:
Und ich habe keine Ahnung. Und ich möchte nicht Teil einer Desinformation sein.
Darf ich Sie um etwas bitten? Halten Sie es genau so. Das Web ist nur dann ein guter Platz, wenn wir es dazu machen.

The last few days I had a lot of fun with Relm4
The last few days I had a lot of fun with Relm4. It is an Elm inspired GTK abstraction.
The main problem I had when using gtk-rs directly was managing state. Either you use a
Rc<RefCell<_>>and pass it around or you use a background thread managing the state and channels to communicate with it.Both ways are tedious.
Relm4 abstracts that away and helps managing state in a much better way:
use gtk::prelude::{BoxExt, ButtonExt, GtkWindowExt, OrientableExt}; use relm4::{send, AppUpdate, Model, RelmApp, Sender, WidgetPlus, Widgets}; #[derive(Default)] struct AppModel { counter: u8, } enum AppMsg { Increment, Decrement, } impl Model for AppModel { type Msg = AppMsg; type Widgets = AppWidgets; type Components = (); } impl AppUpdate for AppModel { fn update(&mut self, msg: AppMsg, _components: &(), _sender: Sender<AppMsg>) -> bool { match msg { AppMsg::Increment => { self.counter = self.counter.wrapping_add(1); } AppMsg::Decrement => { self.counter = self.counter.wrapping_sub(1); } } true } } #[relm4::widget] impl Widgets<AppModel, ()> for AppWidgets { view! { gtk::ApplicationWindow { set_title: Some("Simple app"), set_default_width: 300, set_default_height: 100, set_child = Some(>k::Box) { set_orientation: gtk::Orientation::Vertical, set_margin_all: 5, set_spacing: 5, append = >k::Button { set_label: "Increment", connect_clicked(sender) => move |_| { send!(sender, AppMsg::Increment); }, }, append = >k::Button { set_label: "Decrement", connect_clicked(sender) => move |_| { send!(sender, AppMsg::Decrement); }, }, append = >k::Label { set_margin_all: 5, set_label: watch! { &format!("Counter: {}", model.counter) }, } }, } } } fn main() { let model = AppModel::default(); let app = RelmApp::new(model); app.run(); }I really like that approach!

After about 20 years of using Emacs (not always exclusively) I now dabble into Neovim. 🤯

It's a bit sad how today everybody does a Twitter thread instead of writing a blog post. IMHO most Twitter threads should be blog posts. Same for Mastodon.

It's fascinating to see how far we've come. When I started programming everything was slow.
It's fascinating to see how far we've come. I started programming during a school project, we visualized fractals like the Sierpinski triangle or the Julia set, and it took our computers hours, sometimes even days, to generate those images.
To learn GTK and Rust I implemented a Sierpinski triangle today myself, and I can't even see the program painting so fast is it.
This is still mind blowing to me.

I've been trying to grasp how to structure a Rust GTK application for some time
I've been trying to grasp how to structure a Rust GTK application for some time now. The basic grasp was to use
Rc<RefCell<_>>to pass around application state. That seemed error-prone and cumbersome to me, and I was looking how other applications do it.Today I stumbled upon an approach using message passing, which looks pretty promising to me. Have a look at this blogpost and this github repository. It seems to make handling state much more easy and less error-prone.
I think I will try to implement this approach in a beginner project.
