So I've solved the coupler de-embed issue but am even more confused than when I started.
I updated to the latest upstream VkFFT and, after fixing a shader caching issue that caused problems the first time I tried this, have it working.
The race condition or whatever it was seems to be gone, although I don't have push descriptors working (that's a separate issue).
But it seems to now be behaving consistently in the inverted state: forward to tempBuf1 and reverse …

Finally some progress. But it's baffling.
The very first step of the de-embed filter is to execute FFTs of dinFwd to vectorTempBuf3 and dinRev to vectorTempBuf1.
It appears that somehow the FFTs trade places in the failure scenario, with the frequency domain version of dinFwd being written to vectorTempBuf1 and dinRev going to vectorTempBuf3.
I don't even know where to start debugging this, it smells like something going wrong in the depths of vkFFT with some state …

sha256sum of two buffers with two versions marked "bad" and "good". They have the same hash, but trade places with each other

Organisations are racing to embed AI into everyday life. But people don’t trust institutions and private enterprise to do this in a way that benefits them, and that’s a problem.

I'm so confused I've tried to find any persistent state across de-embed filter invocations and i *think* I've cleared everything out.
If i blow away the fft plan i get no output which is weird and needs further investigation (something not being initialized until the second filter execution or something?).
Wiping all of the VkBuffer's i could find had no effect. I tried adding submits after each shader in case of anything strange happening in command buffers wrt b…

Also you're not going to have much luck bringing ethics to an economics fight. (God I wish that were easier to bring, but you have to bring _regulation_ to an economics fight if you want to embed ethics.)

(The underlying logic here is that LLMs embed biases, so you take advantage of that fact by prompting an LLM to take on a spectrum of different demographic biases that correspond to population demographics, then ask the LLM a polling question in the context of each of those demographically weighted biases.
So yeah, from my OP it might sound like they’re replacing polling with stabbing themselves in the face, but •actually• they’re juggling a bunch of knives and •then• stabbing themselves in the face.)

I completed a checklist item for the #pandemicpond this morning. Retrieving some of the rocks that had fallen into the pond over the past couple winters. Since I upgraded to the rain barrel filters I had made a larger waterfall out of a blue water carrier and the original store-bought waterfall. (See historical pics). But I really wanted to embed it into the rocks and have the water flow out onto flat stones like the ones that line the edge.
Mission accomplished. Here’s some of the evolution.
Short video in next reply.

Peter Singer is a Consequentialist Hedonic Utilitarian Ethicist.
It's his professional job to be good at ethics and teach others about ethics.
He thinks the best ethics are judged by the consequences, and that good is the best for the most people.
He has a podcast. It's probably great. He is cool. I only just heard about it.
But this is his website.
The podcast is offered on Spotify and Apple.
It has an AI chat bot that isn't even prompted well to sound like Peter for no reason at all.
It has a embed for a substack.
That embed for a substack is expired because it's run by a thing called Supascribe that is presumably some software as a service scam.
Below that is a cookie permissions banner which is asking for permission to spy on you for advertisers even though there are no actual adverts on the site.
There are links at the top and bottom to Facebook and Instagram.
There is no RSS feed embedded in the page.
I repeat: Peter Singer is actually pretty cool, and he thinks about ethics sanely.
This is the web we have built. Where a professional Consequentialist Hedonic Utilitarian Ethicist does all this.

1.7x speedup on the 100baseT1 decode from doing the PAM3 demodulation (but not the descrambling) in a shader.
Now the whole baseT1 demo is running at about 8 WFM/s, with a roughly 125ms filter graph execution time (on 80ms of waveform data, so real time would be 12.5 WFM/s)
This breaks down (roughly, not exact due to parallel execution) to:
* 1.3 ms subtract diffpair legs
* 10.6 ms de-embed directional coupler
* 0.6 ms equalization
* 7.5 ms upsample
* 14…
