What are you working on this week? (Apr. 21, 2024)

This week I'm working on the backend for a little platform that I'm making for debating. Where each side can make points and reply to others people's points, then after a point has been argued out to the bottom it either goes green to show it still stands or grey to show there's a good counter-argument. The frontend is made with SolidJS and I'm really having fun making it so far.

Still working on my P2P Lemmy/Reddit alternative. I made the UI prettier and got CI all figured out. It's written with Iroh and Tauri, with React on the FE.

So this week will be filling in the basic features (voting, commenting, etc). And maybe a little bit of testing NAT traversal and whatnot.

If I get super productive, I can start playing around with decentralized moderation. That's the most interesting part of the app, and I have some POC code for it, just need to add in the data and start tuning (will probably scrape some Lemmy data 🙃). Once that's there, I'll be ready to share my project publicly for the first time (😧).

@sugar_in_your_tea @secana sounds fun. You should definitely post the repo when it's ready for contributions.
- Certainly!
  
  I still need to think about what I want in terms of licensing (it's currently MPL 2.0), but once I figure that out, I'd love some help. Also, naming things is hard. 🙃

Probably a little more fine tuning on my news bot. You can see it in action here.

Cool project idea! How did you come up with it?
- I have seen something similar on Twitter a while ago. That one shut down, so i decided to build my own.

I'm still working on a benchmark for my wordle solver. The thing itself works, but I want it to print statuses while benching.

I cannot do it. I've spent hours on this, even tried to make the bench async and run it in a separate Tokio task. I cannot share my bench strict over a thread, and cloning is impossible too, because of something.

Sometimes, the lifetime and ownership stuff of rust really gets annoying. C would've just done the stuff and be done with it. (Maybe)

I you share your code here, maybe someone can help.

The whole code is here

(It does not compile right now)

I understand why it does not work, but I don't know how to achieve what I'm looking for.

This is the code snippet from the binary:

    let wl = BuiltinWList::default();
    let builder: GameBuilder<'_, BuiltinWList> = game::Game::builder(&wl)
        .length(cli.length)
        .max_steps(cli.max_steps)
        .precompute(cli.precompute);
    let solver: AnyBuiltinSolver<'_, BuiltinWList> = cli.solver.to_solver(&wl);
    let bench = BuiltinBenchmark::build(&wl, solver, builder, cli.threads)?;
    trace!("{bench:#?}");

    bench.start()?;

    loop {
        sleep_ms(1000);
        println!("{}", bench.report());
        if bench.is_finished() {
            break;
        }
    }

    Ok(())
}

I'm currently finishing the ext2 implementation on my lib efs, I hope to launch the version 0.3.0 soon!

Cool! It would be cool to get read-only access at least for ext4 for macOS and Windows.

Since it's no_std, are you planning to use this in an embedded project or something?
- Thanks! Actually, I decided to make this library during a OS course in which I made a microkernel (non usable but you can found it here). So currently the project is only to make this library, and I hope other projects will begin to use it if it becomes enough stable ^^
