SneerClub@awful.systems•I was SA'd by Rationalists, AMA.English
3·1 day agoGHB is one of many date rape drugs that people also consume recreationally, and yeah i’m not sure why they love it!
it shares some of bits of appeal with alcohol and benzos. some people also use it to ride out stimulant comedown, or at least to catch some sleep after stimulant use, and this goes for regular stimulants of amphetamine type but also for ketamine (and psychedelics. not sure how much crossover is out there, but it might be a different type of user). i heard that it also has some anabolic effect, but using it for pre-workout would be unwise
i don’t know what kind of approach to workplace drug testing is/was out there, but ghb/gbl is a combination of being rather polar and having no chromophore which all else equal, means that its detection is harder/different compared to other drugs, and being metabolized quickly and also being formed naturally at low levels, which means that detection window is short. ghb lacks groups that typically react with reagent-type tests and instead custom-made strip tests are needed, or lab testing
there also might be general mindset that they’re so rational, that it’s impossible for them to use drugs in harmful ways (famous last words). some people just think of it as an another tool in their toolbox, and figure out that something is wrong only when they wake up strapped to a bed, with half of their face burned and iv line attached, in a psych ward two countries over, if ever

TechTakes@awful.systems•Kevin O’Leary’s giant Utah data centre: will it happen?English
3·1 day agoThe developers claim this thing will use “net zero” water. This is while they want to take water that would normally be topping up the Great Salt Lake and use it to cool the site’s gas power plant.nbs
gas turbines (like seen already in genai dcs) don’t need water for cooling, ccgt powerplant does, but it’s because there’s steam turbine downstream. dc itself could also use evaporative cooling. ccgt has some components with long lead time that will require more planning, footprint and construction than straight gas turbine powerplant

8·4 days agoNothing has changed in that respect, except now we have an extra tool to make sure we get the decision correct.
And I thought the summary did a much more comprehensive justification of the ban than I could have fitted in the modlog, so why not include it?
idk maybe because it’s unnecessary to do that in the first place, and can be filled with nonsense from nonsense generator https://lemmy.dbzer0.com/comment/25880065 emphasis mine

unless i’m to disbelieve my lying eyes, that does sound awfully like llms are in the decision making process

Ask Lemmy@lemmy.world•How bad do you think the oil shock will be?
11·5 days agopeople see strait closed and think of oil because of course there’s a lot of oil going through it, but oil can be routed through pipelines outside gulf so impact on oil is less than that 20% commonly cited
the bigger impact is on gas, because it can’t be transported that easily and it’s closer to 40% of supply. because gas is so hard to transport you can try to avoid doing that, so it’s turned into fertilizer and diesel and aluminum, whose transport is easier, and isn’t as constrained as LNG transport. byproduct of gas mining is helium and it can’t be mined on its own, and while valuable enough to be flown out of qatar supply stops when gas stops. gulf royals have seen that world tries to get rid of oil, so this energy intensive manufacture was intended as a sort of hedge or insurance, but this too stops without transport
so, yeah. things that can be expected to directly get more expensive are energy in general and gas in particular, plastics of all kinds, aluminum, nitrogen fertilizer and to some degree phosphorus fertilizer (uses sulfur as input). and everything that depends on them, which is broadly everything. the only winning move is not to play ie use renewables for energy. these chinese officials who backed renewables buildout are probably the most vindicated people in hemisphere
that said, you can make fertilizer from other fuels, and in other places too, so it’s likely that it will “just” get more expensive, and lower nitrogen use might work about as well because many farmers overapply it. if you are a westerner i guess you might not see it hitting you too hard, but in places like sudan that will be a problem

41·6 days agoit was heading from baltic. well, maybe they used to in vladivostok, but probably no longer
On October 13, 2022, Vostochnaya Verf filed an application with the Primorsky Krai Arbitration Court with a request to declare it bankrupt. According to the results of 2021, the company received a large loss and cannot pay for its obligations.[8]
also lots of heavy industry is where people live, that is in western part of russia. otherwise you have to haul steel all the way there, it would make complete sense to put the only nuclear reactor factory in area where you have all the specialists

Not The Onion@lemmy.world•Iran war oil shortage forces Japan snack giant to use black-and-white packagingEnglish
1·6 days agopigments are the least problem, and many are not dependent on oil, like titania. some might, like soot, but because we’re talking about japan, it’s likely they get it from chinese manufacturer, and chinese chemical industry relies on coal heavily. but it’s such a small part of it all, binder, solvent and the entire packaging are likely petroleum-derived or dependent so there’s close to zero savings here. not to mention fuel and fertilizer use in farming that led to that product
it’s such unbelievably petty corner cutting, the only value of it is in marketing
you know what would help them? switch to solar process heat, best time for it was decade ago, second best time is now (they’re using heavy fuel oil for heating something)
