It's soon 2025 and still nothing about #XCOM 3 :-(

Because Valve's client app does not suck, and Epic's launcher does in fact suck? Perhaps? 🤷

HAAAhahaha

Meanwhile Elon Musk is trying to destabilize the UK.

Maybe take that into consideration next time you buy a car or cheer for SpaceX.

In addition to loopback driver for v4l2 I'm also working still on TPM2 signers patch set for asymmetric keys. Both are off-work business :-) I enjoy working with kernel now like this because I can do features based on my own needs, not on corporate needs... Thus also features are rare because I don't get anything out of doing something if I don't have need for it. Challenge by itself does not drive me for some reason (unless someone offers me money for doing a feature).

I ended up ordering 9990X based machine, which I will later upgrade during its life-cycle to 9990X3D. Should be enough power for my needs in kernel and Rust...

First machine I bought "as a company" as I'm working as a contractor and first machine with water cooling ;-)

It's a custom build from local computer shop with 24 month full service for replacing parts etc. (so I don't have to do that).

BItwig Studio 5.3 will have the feature I've wanted to any DAW for ages: accented notes in the piano roll. So that you can use two logical velocities and then just put them into good values. A HUGE time saver...

From all the features listed, accented notes is my favorite. Wanted it for so long...

Writing down this for myself for the most part to get idea what to write to the cover letter later on.

My RFC driver model for v4l2-loopback will be centered around /dev/video_loop. It has only single ioctl (OOT driver has three), which has N input parameters (describing metadata for the video device) and exactly two output parameters:

1. capture_fd: communications end point for the virtual capture device. Created using anonymous inode.
2. output_nr: /dev/video{output_nr} is the V4L2 device for the output.

There is no query ioctl because any sane program should at minimum know what resources it creates and should not have privilege in the first place to peak others resources.

There is no remove ioctl because close(capture_fd) destroys /dev/video{output_nr}

Neither overlay nor dma-buf support in the initial version (should be reviewed from basis that these can be extended later on).

I have a dev-tree: https://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd.git/log/?h=v4l2-loopback-dev

1. Suck inner guts out of the OOT driver.
2. Wrap it up tpm_vtpm_proxy

So generally looking for advice on:

1. #Pipewire interaction
2. #Gstreamer interaction

Focus on what instead of how. I.e. if this existed how would uapi play for those upstream projects?

This is like something out of medieval king’s court converted into a tweet.

Well, I heard someone working in game industry that the figures I get with Rust when compiling and linking are in par with C++ projects :-) Like compiling Unreal Engine for instance.

Based on Unreal Engine figures 9950X(3D) should be a decent CPU so with "matching" parts on non-ECC memory (with ThreadRipper I'd actually go with ECC memory), we are talking about 4k investment so be it.

This is literally my certificate of ownership for my downtown apartment in Tampere, Finland. I'd call this a proper stock :-) Especially love the tape fix in the middle.

Still I'm now looking into putting my place to digital register and hang this to my wall...

Having used Rust professionally for a while I can say that it is programming language that literally requires latest desktop CPU from AMD or Intel, or to be fully lean something like ThreadRipper. Minimum RAM is rather 64GB than 32GB.

I guess this is progress when a programming language has higher spec requirements than any of the AAA games I'm aware of ;-) No wonder they call Zed as "multi-player editor".

My work Thinkpad melts with Rust and my own M2 Mac Mini Pro (12 cores, 32 GB RAM) can just barely keep up in phase.

PS. I wonder how much compiling Rust code has an effect to the climate change annually ;-) With a Threadripper I could almost literally warm up my house just by compiling Rust.
