I had to look up what possible edible someone might confuse with a death cap.
Apparently there's an Asian mushroom that can be confused with death caps. The secret to not confusing it with a death cap is knowing it doesn't grow in the US. I wonder if this is AI identification going amok, or if there are people from Asia who are foraging it and not realizing the problem until too late.
A sad reminder to make sure your foraging guide is tailored to the area you are in.
My friend told me this story from his antique radio club:
One club member is an audiphile and a former vibrations engineer for automotive companies. He disassembled his speakers and arranged custom housing for the drivers such that, based on his preferred listening spot, the peak of an average waveform from every driver would synchonize exactly at the spot where his ears should be. This, according to him, produces an unbeatable sound. We're talking about opening a speaker and moving its tweeter, like, half a millimeter back.
No, I don't understand how this is supposed to work, let alone consistently.
