We’re ranking danger here. I’d much rather be in the room with dilute peroxide and vinegar than with chloramine or chlorine.

The dose makes the poison. At the concentrations you’d get from household precursors, it would be fine.
Now, take glacial acetic acid and treat it with high-concentration peroxide? Now you’ve got something there. But most people don’t have easy access to either.
Chloroform is the third most dangerous thing on that list.

TenForward: Where Every Vulcan Knows Your Name@lemmy.world•It always bugs me when a character makes this mistake, which happens WAY TOO OFTEN
2·4 days agoI understand you’re not coming from a place of malice. But consider that not understanding why something is important is not a great reason to consider it unimportant if, nearly universally, experts consider it important.

Technology@beehaw.org•IBM CEO says there is 'no way' spending trillions on AI data centers will pay off at today's infrastructure costs
5·17 days agoI used to work at IBM. This guy is a classic case of manager brainrot and has filled the top few tiers of the company with the same. The only reason they make money is the rank and file know how to feed them trendy bullshit that makes them feel smart, which happens to also be a good way of separating other companies’ dumb C-suite types from their money.
But even a blind squirrel finds an acorn every once in a while.
Well, first it’s fire.
Graduate students famously never make mistakes (like including their own hair in samples) and also never smoke weed. So that couldn’t be it.

1·21 days agoIt’s the structure that rolls under the rocket to allow techs to work on the engines and stuff while it’s vertical. It rolls out of the way, behind some heat shielding, before and during launch. Looks like the heat shielding failed or it moved, either way it got cooked.

Let’s save that term for hardware that’s demonstrated reuse in operational flights. So far, I think it’s only Falcon 9, New Shepard, and Electron that have launched paying customers on a reused booster.

SpaceflightMemes@sh.itjust.works•Welcome to the club…? [Daily Hopper]English
6·27 days agoSpaceX was founded in 2002, and announced Falcon 9 in 2005. By 2010 they launched, in 2013 they started propulsive landing experiments, and in 2015/16 they landed on a pad / a drone ship. About 13 years from founding to reuse, and ten years from F9 announcement to reuse.
Blue Origin was founded in 2000, declared first stage reuse a priority in 2013, announced New Glenn in 2016, launched in early 2025, and landed in late 2025. 25 years from founding to reuse, and 9 years from NG announcement to reuse.
I guess the difference is that SpaceX was making money in those intervening years, and Blue was content to, uh, do a lot of simulations I guess.
