Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

This is not debate club. Unless it’s amusing debate.

Want to wade into the snowy surf of the abyss? Have a sneer percolating in your system but not enough time/energy to make a whole post about it? Go forth and be mid: Welcome to the Stubsack, your first port of call for learning fresh Awful you’ll near-instantly regret.

Any awful.systems sub may be subsneered in this subthread, techtakes or no.

If your sneer seems higher quality than you thought, feel free to cut’n’paste it into its own post — there’s no quota for posting and the bar really isn’t that high.

The post Xitter web has spawned soo many “esoteric” right wing freaks, but there’s no appropriate sneer-space for them. I’m talking redscare-ish, reality challenged “culture critics” who write about everything but understand nothing. I’m talking about reply-guys who make the same 6 tweets about the same 3 subjects. They’re inescapable at this point, yet I don’t see them mocked (as much as they should be)

Like, there was one dude a while back who insisted that women couldn’t be surgeons because they didn’t believe in the moon or in stars? I think each and every one of these guys is uniquely fucked up and if I can’t escape them, I would love to sneer at them.

(Last substack for 2025 - may 2026 bring better tidings. Credit and/or blame to David Gerard for starting this.)

the talk about water content in soil was bad but the topic itself was interesting

things that fella got wrong: TDM moisture meter works by measuring what effectively is electrical length of waveguide formed by 2 electrodes and soil around it. more water = higher dielectric constant = longer delay for reflection, this only measures as deep as probe goes snd the rest is fitted from model

neutron detector works just like geiger tube except gas has large cross-section for reaction with neutrons, that gives charged products that begin a spark which is counted. in train, steel doesn't interfere but diesel fuel will. the trick is that cosmic neutrons are counted separately from reflected neutrons, because cosmic neutrons are hot and reflected neutrons are thermal and how much of reflected ones is there depends on water content in the soil. helium does not run out. the more helium you have the faster counts go and you can move faster while measuring with decent precision. the lead shield in train is for getting rid of radiation from granite aggregate under rails, because it contains tiny amounts of uranium and gammas from decay chain would add to noise - lead does not interfere
