Need to let loose a primal scream without collecting footnotes first? 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.

Has anyone heard of Boom Supersonic? Supposedly the company is making a new SST that is supposed to be able to go supersonic without the sonic boom hitting the ground by flying at or above 50,000 feet. They did a demo flight using a a plane that doesn't use the engine tech that the prospective finished plane will have nor does it resemble the prospective airframe design, so it seems like they went fast to prove fast plane is fast I guess?
I just now heard about here. Reading about it on Wikipedia... they had a mathematical model that said their design shouldn't generate a sonic boom audible from ground level, but it was possible their mathematical model wasn't completely correct, so building a 1/3 scale prototype (apparently) validated their model? It's possible their model won't be right about their prospective design, but if it was right about the 1/3 scale then that is good evidence their model will be right? idk, ~~I'm not seeing much that is sneerable here~~, it seems kind of neat. Surely they wouldn't spend the money on the 1/3 scale prototype unless they actually needed the data (as opposed to it being a marketing ploy or worse yet a ploy for more VC funds)... surely they wouldn't?
iirc about the Concorde (one of only two supersonic passenger planes), it isn't so much that supersonic passenger planes aren't technologically viable, its more a question of economics (with some additional issues with noise pollution and other environmental issues). Limits on their flight path because of the sonic booms was one of the problems with the Concorde, so at least they won't have that problem. And as to the other questions... Boom Supersonic's webpage directly addresses these questions, but not in any detail, but at least they address them...
Looking for some more skeptical sources... this website seems interesting: https://www.construction-physics.com/p/will-boom-successfully-build-a-supersonic . They point out some big problems with Boom's approach. Boom is designing both its own engine and it's own plane, and the costs are likely to run into the limits of their VC funding even assuming nothing goes wrong. And even if they get a working plane and engine, the safety, cost, and reliability needed for a viable supersonic passenger plane might not be met. And... XB-1 didn't actually reach Mach 2.2 and was retired after only a few flight. Maybe it was a desperate ploy for more VC funding? Or maybe it had some unannounced issues? Okay... I'm seeing why this is potentially sneerable. There is a decent chance they entirely fail to deliver a plane with the VC funding they have, and even if they get that far it is likely to fail as a commercially viable passenger plane. Still, there is some possibility they deliver something... so eh, wait and see?
Which is absolutely insane. The knowledge to make efficient, modern jet engines is heavily concentrated (for example, India has been trying to build their own jet engines to reduce dependency on the US and Russia and have only managed to get to 1970s-era technology) and I have no expectation for Boom to be able to match that by any means.
It doesn't seem like a viable thing. Is there really enough demand for a supersonic commercial flight with the seating capacity of a regional? The company claims that major airlines have already committed to purchasing the yet-to-exist plane, which begs the question "how committed?" I would highly doubt that without a demonstrator specifically for the passenger version, that any airline would put down any amount of money. I have been known to underestimate the foolishness of leadership, so maybe there is an inked deal as opposed to a handshake for x number of planes, though only at y price.
In concept, supersonic aircraft are cool. Going fast is really neat. I think those are the feelings Boom is banking on, which is sad because I feel that their airliner is vaporware.
Yeah, the commitment might be only a token amount of money as a deposit or maybe even less than that. A sufficiently reliable and cost effective (which will include fuel costs and maintenance cost) supersonic passenger plane doesn't seem impossible in principle? Maybe cryptocurrency, NFTs, LLMs, and other crap like Theranos have given me low standards on startups: at the very least, Boom is attempting to make something that is in principle possible (for within an OOM of their requested funding) and not useless or criminal in the case that it actually works and would solve a real (if niche) need. I wouldn't be that surprised if they eventually produce a passenger plane... a decade from now, well over the originally planned budget target, that is too costly to fuel and maintain for all but the most niche clientele.
