Status update, May 2021 May 16, 2021 on Drew DeVault's blog

Hello! This update is a bit late. I was travelling all day yesterday without internet, so I could not prepare these. After my sister and I got vaccinated, I took a trip to visit her at her home in beautiful Hawaii — it felt great after a year of being trapped within these same four walls. I hope you get that vaccine and things start to improve for you, too!

In SourceHut news, I’ve completed and shipped the first version of the builds.sr.ht GraphQL API. Another update, implementing the write functionality, will be shipping shortly, once the code review is complete. The next one up for a GraphQL API will probably be lists.sr.ht. After that it’s just man.sr.ht, paste.sr.ht, and dispatch.sr.ht — all three of which are pretty small. Then we’ll implement a few extra features like GraphQL-native webhooks and we’ll be done!

Adnan Maolood has also been hard at work improving godocs.io, including the now-available gemini version. I wrote a post just about godocs.io earlier this month.

Here’s some secret project code I’ve been working on recently:

use errors;
use fmt;
use linux::io_uring::{setup_flags};
use linux::io_uring;
use strings;

export fn main() void = {
        let params = io_uring::params { ... };
        let ring = match (io_uring::setup(32, &params)) {
                err: io_uring::error => fmt::fatal(io_uring::strerror(err)),
                ring: io_uring::io_uring => ring,
        };
        defer io_uring::finish(&ring);

        let sqe = match (io_uring::get_sqe(&ring)) {
                null => abort(),
                sqe: *io_uring::sqe => sqe,
        };
        let buf = strings::toutf8("Hello world!\n");
        io_uring::write(sqe, 1, buf: *[*]u8, len(buf));
        io_uring::submit_wait(&ring, 1)!;
        let cqe = match (io_uring::get_cqe(&ring, 0, 0)) {
                err: errors::opaque =>
                        fmt::fatal("Error: {}", errors::strerror(err)),
                cqe: nullable *io_uring::cqe => {
                        assert(cqe != null);
                        cqe: *io_uring::cqe;
                },
        };
        fmt::errorfln("result: {}", cqe.res)!;
};

The API here is a bit of a WIP, and it won’t be available to users, anyway — the low-level io_uring API will be wrapped by a portable event loop interface (tentatively named “iobus”) in the standard library. I’m planning on using this to write a finger server.

Status update, May 2024

Hi! Sadly, I need to start this status update with bad news: SourceHut has decided to terminate my contract. At this time, I’m still in the process of figuring out what I’ll do next. I’ve marked some SourceHut-specific projects as unmaintained, such as sr.ht-…

Automatic case design for KiCad

I don't generally get along great with CAD software with the exception of KiCad. I guess the UX for designing things is just a lot simpler when you only have 2 dimensions to worry about. After enjoying making a PCB in KiCad the annoying for me is alwa…

The floor is lawa!

And now for something completely different… When was the last time you were excited about a simple window with nothing but a single background color? Well, I currently am. Let me tell you about it… This window is notable, because it was created using the ”pu…
