It feels suboptimal that each fedi service requires a different account.

e.g. I have a Flohmarkt instance, which is different from my Mastodon instance. If I also ran a pixelfed instance, that would be a third account.

Rather than one "me", with different linked services.

Perhaps there is a need for a fedi directory service / "main" account, which people can use for discovering of sub-accounts?

(I can see that, for some users, separation of accounts will be valuable, so I wouldn't want to remove that ability.)

C library and Rust crate recommendation of the day:

1. C: https://github.com/emoon/minifb
2. Rust: https://github.com/emoon/rust_minifb

This is pure gold!

A simple no bullshit framebuffer that dumps to X11/Wayland/macOS/iOS/Android/Web(WASM).

I feel like wasting time a lot for nothing (psychologically) but at the same I think here lies the main reason why this driver has not moved really :-)

In order to modify the driver you would have to change the stack around it, which is destined not to be compatible what the upstream expects. There's no tools outside v4l2-loopback stack that you could really use for testing the camera side, when you start breaking the API.

So in order to start doing even basic changes to the driver (other than make it compile as in-tree driver), something that resembles enough stack is a mandatory requirement. Thus, this silly demo is sort of like v4l2-loopback tools emulator...

After trying bunch of things over the last few weeks I finally have a test program for feeding the data for a video loopback device, i.e. to work as fake webcam:

- Has zero dependencies other than libc. Draws the frames, converts the pixel formats and writes them to the device.
-.Has optional debug display using minifb.
- Predictable cyclic motion, which useful in future for automated testing.

Repository: https://codeberg.org/jarkko/v4l2-loopback-test/
BuildRoot package: https://codeberg.org/jarkko/linux-tpmdd-test/src/branch/main/package/v4l2-loopback-test

I've not been able to make any major changes to the driver I would like to do because it does not make much when being blind. Now it is finally possible to forget user space and move on to the kernel changes.

@pksu It was vaporware ;-)

I made some noise:

Makes no sense. And first and foremost it does not make sense for Microsoft.

Some people know what they are doing! The same guy is working also on a port of Elite. For VIC-20 (with memory expansion to 35 kB but still).

Fedora Server Working Group has created a
10 question survey aimed at people who use Server.

https://fedoraproject.limequery.com/fedora-server-f41

The goal here is to increase our knowledge of how people use the Server
offerings and what they do with it. In turn, this will help us priotise our efforts into areas that actually matter to our users.

Answering this survey will not take a lot of time, please consider helping us to help you with Fedora Server development.

@Aissen With Audacity telemetry feature generated bunch of forks. I hope this does not have the same effect (you can disable AI from settings easily).
