With Facebook currently in the news again, it's perhaps worth pointing out that I left the platform 11 years ago because they were already generating fake replies to fake posts, presumably in an attempt to increase engagement with ads. I got rid of my account and blocked facebook URLs and IP addresses on my router so that I cannot accidentally engage with any of their stuff at all.

That is of course not the only thing which was bad about Facebook. By 2016 they were working to undermine democracy.

So there's nothing actually knew about the harm they're causing now. It's been obvious for more than a decade which direction they were heading in. But I'm happy that there's more awareness now.

So, have you all deleted your facebook / instagram and whatsapp accounts already ? If not, why not ? Meta, just like Twitter, has been a nazi bar for some time now.

The tech thing outside of crypto bro bullshit that got me interested in Polkadot is some "math inventions" in the distributed computing.

If you distribute block generation let's say by N in a blockchain you easily end up to an architecture where also network security also divides by N.

What Polkadot and its spec generalization JAM (https://graypaper.com/) do differently is that with the help of game theory parallel chains balance back in collaboration.

The basis of all this is described in this math paper: https://eprint.iacr.org/2024/961

With these shenanigans, the network sort of creates a scheme where you have a distributed computer where the relay chain is actually just part of the overall machinery tracking the history.

What I personally work on is a RISC-V relative bytecode VM called PVM, which has eight registers instead of 16 and immediate ECALL. This speeds up JIT over let's say WASM or eBPF given that register allocation to ARM and x86 becomes much more straight-forward process and generally it is more close proximity of those CPU architectures. I.e. what I hack is essentially a software-defined compute core and overall this network forms a sort of like "GPGPU" infrastructure.

The value part is more to optimized to book keeping than increase investor value so that you can make shared services where everyone gets their part when being a sub-provider of some service. E.g. there's no fixed number of tokens but there's instead rate-limited inflation.

So yeah, I'm not interested in blockchains or cryptocurrency per se but I'm very interested on distributed systems and providing alternatives to a data center. I think this make this work valuable.

In kernel-ark:

1. "make dist-fedora-configs": Can I make only process x86 stuff and not all the archiectures?
2. Let's say I've applied patches containing a new kconfig flag. How to fix that up?

A Rust question. Command::env_clear() has this example:

use std::process::Command;

Command::new("ls")
.env_clear()
.spawn()
.expect("ls command failed to start");

Isn't that like "do nothing" given that the instance Command was just created? I don't understand this example.

I wonder if a kselftest written with Python can depend on GStreamer? I.e. check and skip on failure.

I'm almost done converting the demo shown in my screencast from bash and fmpeg to python and gstreamer [1]. There has been bunch of blockers, like for example getting Python bindings compile in my BuildRoot environment (stable version bump helped).

One final peace that I was missing was how to pass a file descriptor to GStreamer pipeline but here it is:

https://gstreamer.freedesktop.org/documentation/coreelements/fdsrc.html

So... 1.5 weeks of scratching my head but this all work was absolutely required before making the breaking API change to the driver code (i.e. return file descriptor to an anoymous inode in the ioctl instead of writing to /dev/video0).

Now I need only a small tweak to the test program when I test that kernel change. FINALLY ready to go back to the fun i.e. kernel hacking ;-)

When writing a system test for a media (aka V4L2) driver, Python and associated GStreamer bindings seem to be overall the sweet spot.

It has these perks:

- Packaged (unlike ffmpeg bindings).
- Can be injected during the post build.
- Has videotestsrc ;-)

This is crucial if Arch Linux wants to be also a commercial option. Sloppy license management keeps it in the hobbyist niche.
