Examples are not Documentation

Examples ARE usage documentation.

What value is this blog supposed to be adding exactly?
The fact that top-level and API descriptive explanations are important?
The fact that some projects don't have complete documentation?
To whom exactly would this be considered new information?

Ladybird announcement

A reminder that the Servo project has resumed active development since the start of 2023, and is making good progress every month.

If you're looking for a serious in-progress effort to create a new open, safe, performant, independent, and fully-featured web engine, that's the one you should be keeping an eye on.

It won't be easy trying to catch up to continuously evolving and changing web standards, but that's the only effort with a chance.

Intel Arc B580 tested in five games on Linux; you’re better off sticking with an AMD GPU for now

What serious Linux users buy GPUs based on raw gaming performance on release week?

I personally buy based on open-source driver support. And this includes long-term active support, AND developer approachability.

My current GPU is an AMD/Radeon one because of that. But I'm reconsidering my position when my next hardware upgrade comes.

I reported an AMD GPU driver issue to mesa once. It was tested, confirmed, and patched by a competent AMD developer within a few days. Now you have easily reproducible issues like this not even going past the testing phase after many months. And there are similar issues across all model generations.

If I were to upgrade my workstation next year, I would probably go with an AMD CPU and an Intel GPU, which is the exact opposite of my current setup 🙃. One should never rely on outdated perceptions.

Async Rust Is A Bad Language

fn foo(&big, &chungus)

is out,

async fn foo(&BIG_GLOBAL_STATIC_REF_OR_SIMILAR_HORROR, sendable_chungus.clone())

is in.

Or maybe you know

fn foo(&big, &chungus)

is out

async fn foo(big, chungus) -> (big, chungus)

is in

Or

async fn foo(big, chungus) {
  // ...
  tx.send((big, chungus)).await?;
  // ...
}

is in

Moving (movable/sendable) data is not limited by number or direction, you know. And that second one even makes use of them great Hoare channels! And gives us control on how long we hold on to data before sending it back (modified or not). But I digress. Let's go back to the important talking point that Hoare was right!

The ???? operator

Is everyone genuinely liking this!

This is, IMHO, not a good style.

Isn't something like this much clearer?

// Add `as_cstr()` to `NixPath` trait first

let some_or_null_cstr = |v| v.map(NixPath::as_cstr)
  .unwrap_or(Ok(std::ptr::null()));

// `Option::or_null_cstr()` for `OptionᐸTᐳ`
// where `T:  NixPath` would make this even better
let source_cstr = some_or_null_cstr(&source)?;
let target_cstr = target.as_cstr()?;
let fs_type_cstr = some_or_null_cstr(&fs_type)?;
let data_cstr = some_or_null_cstr(&data)?;
let res = unsafe { .. };

Edit: using alternative chars to circumvent broken Lemmy sanitization.

Curl: Hyper, is it worth it?

As a user of both libcurl (haven't followed it's development for years though) and hyper, I'd say either commit to making hyper the default at some point and make that a priority, or drop it altogether. And since there is no intention/plan to do the former, then latter does indeed follow logically.

Which code style to initialize structs?

Neither.

  • make new() give you a fully valid and usable struct value.
  • or use a builder (you can call it something else like Partial/Incomplete/whatever) struct so you can't accidentally do anything without a fully initialized value.

Maybe you should also use substructs that hold some of the info.

Free-threaded CPython is ready to experiment with!

While pure Python code should work unchanged, code written in other languages or using the CPython C API may not. The GIL was implicitly protecting a lot of thread-unsafe C, C++, Cython, Fortran, etc. code - and now it no longer does. Which may lead to all sorts of fun outcomes (crashes, intermittent incorrect behavior, etc.).

Announcing Freya GUI library

Languages: Just Rust!

You got my attention.

fn app(cx: Scope) -> Element {
    let mut count = use_state(cx, || 0);

    render!(
        rect {
            height: "20%",
            width: "100%",
            background: "rgb(233, 196, 106)",
            padding: "12",
            color: "rgb(20, 33, 61)",
            label { 
                font_size: "20", 
                "Number is: {count}"
            }
        }
        rect {
            height: "80%",
            width: "100%",
            background: "rgb(168, 218, 220)",
            color: "black",
            padding: "12",
            onclick: move |_| count += 1,
            label { "Click to increase!" }
        }
    )
}

Oh, it's stringly-typed Rust.
Yeah, no thanks.

What is going on with serde?

I hate that I'm linking to Reddit, but I'm just reminded of this.

Some of us knew where all the obsession with dependencies' compile times will lead, and triggered the alarm sirens, if half-jerkingly, years ago.

Compile times, and more specifically, dependencies compile times, is and has always been the most overblown problem in Rust. We would have some sort of sccache public repositories or something similar by now if it was that big of a problem.

And yes, I'm aware proc-macro crates in particular present unique challenges in that field. But that shouldn't change the general stance towards the supposed "problem". And it should certainly not trigger such an obsession that would lead to such a horrible "solution" like this serde one.

Post-YouTube: Why Aren't We Embracing IPFS?

Why Aren't We Embracing IPFS?

Because it's an overhyped joke successfully utilized by crypto scammers.

Neither content addressing, nor distributed hash tables (or key-value stores, or whatever) were novel ideas.

The combination of the two is not a novel idea.

For p2p, torrents, work as another user already pointed out (initial realease 2001).

For a distributed filesystem, look at Tahoe-LAFS (initial release 2007).

For a full anonymous p2p distributed filesystem, check out (real) Freenet, called Hyphanet now (initial release 2000).

And no, if you need anonymity, an anonymous transport (e.g. using libp2p) is not enough. You need to consider anonymity at each step like Freenet does.

These are three real non-overhyped products one can draw inspiration from. IPFS? not so much.

You can look around for more examples. I always found this Wikipedia page about file sharing in Japan interesting, since it mentions networks not well known to the rest of the world: https://en.wikipedia.org/wiki/File_sharing_in_Japan
