@mcc Do you mean with an implementation where you compute each pixel independently?

@patcharcana what's the nature of difference between condo associations and hoas? Is there an important legal difference (e.g. is ownership of condos set up differently), or is it a practical difference (caused by the social situation being different, or by the needs being different, or ...)?

If you go this route, you might wish to know that the set of phones that have a barometer is somewhat weird (it's neither the more fancy ones nor the less fancy ones that are significantly more likely to have one ttbomk).

@_thegeoff do you have experience or ideas on how to mask off infrared leakage from an emitter to a detector that are next to each other (the intent is to detect reflections/diffuse reflections)?

I currently have 5mm IR LEDs and a photodiode next to each other, in black heat shrink that extends down to the slight ridge in the base, but don't overlap it. I still get significant signal when there's nothing in front and adding more layers of heat shrink doesn't help. My best guess is that I am seeing emission going backwards and scattering off the pcb into the photodiode, but am somewhat unsure how to deal with that given that I need something ir-opaque, nonconductive, and able to withstand the heat of soldering.

Aaand the media file got lost.

This is not a sound recording; it's a recording of intensity of reflected IR. :)

It seems that black heatshrink and aluminium foil are much less IR-translucent than heatshrink of other colors and cardstock. Heatshrink of other colors isn't that surprising, but I was really surprised to see how translucent cardstock is.

That resembles the Swiss situation, where formally there is no capital, but there's a larger-than-anywhere-else density of federal institutions in Bern.

WTF Osram, why do your LEDs have longer cathodes than anodes? (https://look.ams-osram.com/m/6985efa866041336/original/SFH-4547.pdf)

@argv_minus_one

I'd rather say that an antenna is a light (albeit usually at a weird frequency) emitting capacitor (unless it's an inductive antenna, which is a light-emitting inductor). IMO CRT is a bit cheating; it's as much a capacitor as a vacuum tube is a capacitor.

Well, ok, but _why_? _What_ is the system of equations that leads to this absurd outcome during search for valid initial values?

@munin

I'm curious whether this is something that makes the situation with truthfulness worse or better in the same session. I would estimate worse, because that matches a pattern of someone digging themselves further in while being abused by an authority for their failures that's common in _some_ stories and repetitive when present.

@munin

Was he aware of the options? Was he able to do something other than trust the LLM about any sort of isolation being set up correctly?

I suspect that the answer is no, because otherwise it's hard to believe him not thinking about that for days.

@0xabad1dea What's a stoptrain?

@whitequark @0xabad1dea

I also don't really know, but a recording with a smartphone's microphone is unlikely to have significant harmonics at reasonable volumes (I once looked at recorded spectra of sweeps generated by a PC speaker, and they appeared fine modulo diminishing response as the frequency increased) and has some sort of reasonable frequency response up to ~15kHz. What I find most interesting here is what kind of frequency peaks are there, so the potentially-nonflat frequency response is not that important either.

@whitequark @0xabad1dea

Would you mind recording the sound and sharing the recording (or a picture of the spectrogram)?

@azonenberg Ok, so you are looking for correlation (and not necessarily clustering)?

@azonenberg

Does scores from raads-r actually cluster? Based on nothing but intuition (probably driven by poor quality sources) I would expect no pronounced boundary there.

@rysiek @briar @cwtch @VeilidNetwork

I think a list like this is a nice to have as a reference, ideally one that might still be reasonably up to date years from now. People used to have lists of various recommendations/interesting things by others on their websites. Perhaps it's something that would make sense for you to have?
