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 ^^

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 have seen something similar on Twitter a while ago. That one shut down, so i decided to build my own.

I do quite like that idea, I think I’ll have the best points from each side at the top, the ones that have been disputed at the bottom, and the ones currently in discussion in between. This will hopefully give an overview of the best arguments from both sides.

On a separate note, I was thinking of using this for more political discussions but I do like the idea of having technical subjects as well so will add them in.

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. 🙃
