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

Great start for a year. I have a tech job. I've started to work on two new kernel features after some more quiet period. Could be worse.

"leading programming language", "the most popular programming language" etc. Why it is a thing to rank this? I get gathering statistics but not it being an up-front thing.
I have not yet had a job where I would need such list for accomplishing anything :-)
Company/organization-wide decision making might need to look at such statistics for making long-term choices perhaps. It's pretty useless information overall...

Great found the most suitable crate for my test program:
https://github.com/zesterer/euc
I.e. I can pre-render the frame to buffers and then loop those frames to "cast_fd" with a given FPS (25) so it should be fairly timing accurate.
Using rotating and shaded torus I have cyclic movement which the other side (opening /dev/video0) can then read and store a full cycle of the animation.
Client and server can be two threads in the same process, and as final step the client can compare that the read frames are close proximity enough to the pre-rendered frames.
That should create a full headless and "CI friendly" system test for v4l2-cast. Definitely still hold a bit before doing too heavy refactoring and make this happen!
I wonder can we already have Rust programs in kselftest's? My driver is in C but this could be potentially part of the kselftest (at some point).

mjg59@nondeterministic.computer"Today, most of the major streaming media platforms utilize the TPM to decrypt media streams, forcefully placing the decryption out of the user's control." (from https://www.defectivebydesign.org/dayagainstdrm) I… just… what? This isn't even slightly true. There's plenty of good reasons to object to Microsoft imposing hardware requirements on Windows 11 that aren't strictly required, but *nobody* is doing media decryption on a TPM because TPMs are nowhere near fast enough to do that

During next 12 months the goal is to get official LLVM target for PVM:
https://www.youtube.com/watch?v=Jq8XBs1wPhg
Right now PVM "software-defined ISA" is recompiled from custom RV32E/RV64E targets so this will flatten things a bit.
We are not doing cryptocurrency, we are more like doing a data center as a distributed blockchain. I.e. un-cloud the cloud.
The whole discussion focused around bad investments, meme coins and currency is just plain silly. Mediator/ledger is the cosa nostra scheme to collect high fees in most of the high value internet services.

I will name my driver as "v4l2-cast". The ioctl will return the file descriptor with the field name "cast_fd".
Feels Platonic sense the best possible name, i.e. you have video capture and video cast devices.
It is more like user space video capture driver than loopback/proxy device. And we have too many things already named as "proxy" or "loopback". They are as descriptive if I named this as v4l2-object or v4l2-instance IMHO. From "cast" you get immediately a gist what is going on and like the use and purpose.
