ethbr1 1 hour ago | parent | context | flag | favorite | on: EPA moves towards banning leaded aviation gas "Do no harm at all costs" regulatory bodies need to be overhauled. E.g. NRC, FAA IMHO, it'd be much better to have an explicitly adversarial and separately-funded dual-track system at such agencies, similar to how the justice system works. E.g. FAA-Innovation (responsible only for their goal) makes their strongest case and presents research on why unleaded gas should be adopted ASAP. FAA-Safety (responsible only for their goal) makes their strongest case on why no change should be made. All arguments and facts are published in public. Then higher-level decision makers arbitrate and make a call. The root of all evil is that from a career perspective, "defer and take no action" is always safer for individuals in positions of regulatory authority. Worst case, something that's always been wrong explodes, and you blame it on the last person. In the current blended safety+innovation system, it's too easy to obfuscate intentional inaction in endless "more study is needed" bullshit. reply

we already have agencies responsible for trying to ram evil and destructive policies down the throats of the public; they're called lobbyists we don't need dedicated redundant government branches with the same mission, for gently caress's sake (the "evil faa" wouldn't be able to pay as much as existing lobbying groups anyway, starving them of "talent", so even libertarian morons should recognize that it would be an inefficient means of ruining the world) Internet Janitor fucked around with this message at 20:37 on Oct 27, 2023 |

There has been exactly one (1) aviation fatality on a scheduled commercial airliner in the USA since the Colgan air crash in 2009. It was the lady that got partially shoved out of a hole in the fuselage that was left by a fan blade breaking off on some long-haul airliner a few years back. A tragic freak accident and not really something that could have been 100% prevented given our current understanding of materials science. Even then there's an argument to be made that maybe you don't want to have people sitting too close to the rotation plane of an airliner's N1 fans on account of uncontained engine failures like this one happening every now again. But yeah, one fatality, not even one crash. I'd say the modern-day FAA is doing pretty drat good, although given the way that US ATC keeps trying to make two airplanes occupy the same runway at the same time lately I feel like the next big accident is a case of when and not if. The guy might maybe have an argument for general aviation, since there are Cessna 172s with a price tag north of half a million (this is for the aviation equivalent of a driver's ed Toyota Corolla) rolling off the production line today that still use some piece of poo poo piston engine designs from the 1970s that are only certified for 100 octane leaded gasoline. And these things fail constantly, often right after take-off, giving the occupants a (statistically) coin-flip chance of walking away from the resulting forced landing or going home in a wooden box. That's way too risky for my liking and the main reason why I haven't pursued a pilot's license even though I'd rather like to. Meanwhile there are a lot of cheaper and more advanced GA aircraft designs coming out of the EU, many of which use piston engines derived from modern-ish automotive diesels, and they even run on standard jet fuel instead of leaded gasoline. The euro companies are also developing some electric engine designs as well, but their endurance leaves a lot to be desired at the moment. Even then it's pretty cool to watch the demonstration videos where the pilot reduces power during taxi or final approach and the propeller just ... stops. And then immediately starts again when needed.

sillysaurusx 2 hours ago | parent | next [–] Oh no, kids might see a butthole. One sentiment that’s different from when I was a teen till now is that the youth today is so afraid of nameless authorities. No one wants to do anything even slightly controversial, lest their peers drag them for it. I fondly remember my first butthole. It led to tubgirl and to that one video of the fella having his throat cut after being stepped on by a boot. I was about 11. I turned out ok, and I don’t think it’s survivorship bias. Speaking as a father now, when Kess grows up a bit, I’ll likely give her unrestricted internet access. And I’ll bet you a signed dollar that she’ll turn out ok.

ProllyInfamous 1 hour ago | next [–] I always carry a two dollar bill and fifty-cent piece, for when (e.g.) an entry-level store-clerk does something which most-other-clerks wouldn't resolve, I can say to them "Thank you for giving. a . poo poo." As a blue-collar electrician (although retired), I want to hire anybody that seems to give even the tiniest poo poo. While working, it took me a decade to realize that "if you're the only person that 'gives a poo poo,' YOU'RE GONNA HAVE A BAD TIME." reply

$2 bills are extremely uncommon, to the point that many people have never seen one and assume they're fake. this impression is emphasized by the fact that they don't circulate much (and the easiest way to obtain them is directly from a mint or bank), so they tend to be unusually crisp and umblemished, like a counterfiet bill imagine somebody handing you a "27 euro" bill that looks like it's made from a different material than everything in your wallet while insisting belligerently that it's legal tender

they’re not in common circulation, more of a traditional thing that you can request if you want. generally they go straight back out of circulation if you spend one because merchants don’t give them as change. so it’s pretty common that people working registers don’t know about them and think they’re fake

there are sort of natural reasons for $2 bills to have this status, you don’t want a ton of different denominations taking up space in a cash drawer, and 1/5/20/100 is a nice progression that lets you make change for anything reasonable without ever having to give more than four of the same bill back. $2 and $10 don’t really carry their weight in this system. people would think not having a $10 was weird, but it is used way less in practice — e.g. you might get one in change, but atms don’t generally give them out. (this is an extra layer of joke for the line in that lonely island song about “dropping hamiltons” (hamilton’s face is on the $10 bill): a baller throwing money around could reasonably have stacks of $20s or $100s, but having $10s would have to be a deliberate cheapness.) but $2s are just completely skipped over

there are a couple of machines around here that will only give you one ten per transaction. “sure, you can take out $50, but don’t get fancy!” I think the ten-compatible machines also tend to be attached to banks, up here at least

yeah, bank atms have more options, but my bank doesn’t seem to have any that do $10s — it’s either 20/100 or 5/20/50/100. but the atms you might see in bars or corner stores will generally just do $20s because it’s way simpler for whoever manages it to deal with

photochemsyn 3 hours ago | root | parent | prev | next [–] My conspiratorial (*completely evidence-free as far as I know) theory on hookup apps is that they're secretly backed by the major pharmaceutical manufacturers of various STD treatments. The numbers are interesting: there are about 32,000 new HIV cases in the USA each year, and the per-month cost of ongoing anti-retroviral therapy is estimated at $1,800 - $4,500. This works out to a gross cost of ~ $0.7 billion to $1.7 billion - and it's cumulative, year after year. as HIV patients need this treatment for the rest of their lives. Given profit margins of 10-15% in pharma at least, this is a huge cash cow for the industry. (Also explains the reluctance to invest in seeking a permanent cure for the disease that would allow patients to terminate their therapy). Now, would a profit-hungry industry deliberately encourage reckless sex practices in order to grow demand for their product, year after year? It might bear some investigation. -- yes that must be it. there's no other reason people would get horny and want to use an app for finding people who wanna gently caress.
