The various extraordinary renditions during the "War on Terror" seem to be an existence proof that the USA is able to act as it pleases in other countries, especially when it is focused on a small number of persons.

I agree that the country is not 100% successful but that does not prevent the nation from trying to act.

Of course you should cut corners when you need to get somewhere fast. Ambulances go through red lights!

That is a deeply unfortunate line to see.

Humanity has known for decades that "[most medical calls] don’t dramatically worsen in the course of a very few minutes, and they don’t spread from person to person" (Journal of Emergency Medical Services, 2017).

In the case of red lights and sirens, maybe they made sense before bystander CPR and before we had empirical data. But not now.

The overuse of red lights and sirens doesn't save lives. It ends them.

I wouldn't call them "common-sense". When a modern-day tragedy (death of a child) is required before "hug a tree and survive" becomes a slogan, it seems safe to say that they are counter-intuitive.

If humans did the right thing by default (e.g. "If you are lost, 'Hug-A-Tree' and stay put."), there would be fewer sad stories.

As anecdotal support for "constantly tasting everything", I offer my high school scientific calculator. After one year of 2 hrs per day of chemistry class, its crevices around the display had a permanent collection of precipitate.

I suspect that even without intentionally tasting things, nearly everything in a lab is ingested as an aerosol. It would be unsurprising if months of such exposure led someone to develop a hunch about a molecule.

If you're looking for an experimental protocol, the ADHD MTA trial's protocol looks pretty good.

It is described at https://pubmed.ncbi.nlm.nih.gov/10591283/ and explains in detail how the doctors decided when to try increasing the dosage. It supports evand's assertion that improvement should be noticeable quickly.

How much ambient light is there? Is it all from sunlight?

Sometimes there's some sunlight through the window, when it's night or I have the curtains closed then my light comes only from one wrapping of fairy lights around the perimter + a 500 lumen lamp + my laptop screen. (the room's main light broke)

  1. Find a company that makes or sells high quality LEDs
  2. Buy their largest lighting fixture.
  3. Install fixture.

Sample companies:

  • Waveform
  • Yuji LED
3Brendan Long
Corn bulbs from Yuji LED seem like the best option for this question, since you can just get a giant bulb and plug it into a normal fixture (if you don't mind a giant bulb sticking out of it). Waveform's linear fixtures are definitely nicer if you're willing to spend an some time screwing their mounting clips into the wall though.

I got a little weirded out at the OAuth prompt because it said "johnny" wanted to get my account. I know who Neuronpedia is. I didn't know who "johnny" was until I did some more reading and figured out that you're Johnny.

Please consider registering a dedicated account for the organization ("Neuropedia", perhaps) and doing the OAuth through the organization's account so that the prompt doesn't surprise users as much.

Sorry about that! Should have fixed that way earlier. I've transferred the app to "Neuronpedia", so it should appear correctly now. Thank you for flagging this.

In a later comment, the original poster said that the Total Protein seemed fine. Unfortunately, https://www.ajkd.org/article/S0272-6386(99)70278-7/fulltext suggests that the person looking at the labs would have to know that they ought to look closely at the albumin level, specifically. It wouldn't be the first time that "Reality has a surprising amount of detail" where overlooking 1 thing is enough to get into trouble.

It is also possible that his lab values fell just barely within the normal ranges.

Maybe, although the OP does say "How could something as fundamental as protein deficiency not be a standard, ordinary thing we test for?", so it sounded like it hadn't been tested at all.

But yeah now you've made me want to criticize the whole idea of normal ranges! One time I had a vitamin D deficiency that had me extremely ill for three months and even bedridden for part of that time, but clinically it was only mildly out of range, and the doctor just told me "Your vitamin D level is a bit low" – which I feel didn't sufficiently suggest that it might be t...

FYI, the Waveform article promotes the use of the Kruithof curve but that relationship between lumens and preference could not be replicated by a study from 1990 (https://doi.org/10.1177%2F096032719002200102).

The content may be public but does copyright law allow these sorts of quotes?

Which venue controls Facebook posts' copyright? I assume that Lesswrong.com's liability is also affected by the law that applies to the location of Lightcone's office.

Do you mean that the container with the contaminated fuel was stored outdoors in the container that you linked to?

If yes, then a couple things come to mind:

  1. Did you confirm that the container was watertight?
  2. Is it possible that the relatively small size of water molecules meant that they could sneak past mechanisms designed to hold back large hydrocarbons?
2jefftk
Yes. I put 5gal gas (plus the recommended small amount of STA-BIL) into the linked container, and stored it outdoors, yes. 1: I didn't. It's possible I didn't close it correctly? This seems like the most likely possibility. 2: Modern gas cans are vapor-tight so it seems to me they should be keeping water out.

Are you limiting the phrase "Social Security" to the funds given to the elderly or are you including things like disability payments?

It seems that having a teacher tell you when to move up/onwards is critical. Otherwise, it can be tricky to realize that the hardware is the limitation after months of working on your own abilities/skills.

Calling 911 or your local emergency number is also a good default action because the call taker should be trained to walk you through some of the things the post described.

Don't be afraid of creating duplicate 911 calls for something like a big fire or car crash. Merging duplicates and rapidly closing out unnecessary calls is the communications center's job, not yours.

Expect to be asked for a description of the problem and your location. Don't worry if you don't know an exact address. You may also be asked for your phone number.

It is also OK to indicate that you are uncertain about something such as whether or not the patient is breathing.

3bortrand
Definitely agree. Especially if you're training is limited (but even if it isn't) making sure someone reaches emergency services should be your top priority. If you need to attend to the injured person, pointing out a specific person and telling them to call 911 is a good approach. It's more likely to get done quickly if a specific person feels it's their responsibility than if it's unclear whose job it is.

I recognize many of the institutions you mentioned such as Nvidia and MIT. How confident are you that the more obscure ones like Hugging Face are trustworthy?

1Gabe M
I'm not sure what you particularly mean by trustworthy. If you mean a place with good attitudes and practices towards existential AI safety, then I'm not sure HF has demonstrated that. If you mean a company I can instrumentally trust to build and host tools that make it easy to work with large transformer models, then yes, it seems like HF pretty much has a monopoly on that for the moment, and it's worth using their tools for a lot of empirical AI safety research.

The title says "Reflecting on the 2022 Guild of the Rose Workshops" but the article does not discuss the results of the workshops or the experiences related to operating them. Instead, the article lists the contents of each past workshop.

How do you think the employees in charge of the signs will benefit if they start omitting the phrase?

Somewhere along the line, somebody will have to deal with fewer irate passengers who just missed their trains because the signs were too small and verbose. I would agree that it is unlikely for anybody who can do something about the problem to connect the unfortunate signage with the irate passengers, though.

An article about an airplane crash reported an example of over-fitting caused by training in the airline industry. 

Pilots were trained in roughly the following order:

  1. How to recover from a stall in a small airplane by pushing down on the yoke.
  2. Later, they were trained in simulators for bigger planes and "the practical test standards ... called for the loss of altitude in a stall recovery to be less than 100 feet. ... More than a hundred feet loss of altitude and you fail."

It seems that the broken hand example is similar to situations where we have a deep understanding of the mechanics of how something works. In those situations, it makes more sense to say "this leg is broken; it cannot do 99% of the normal activities of daily living." And the doctor can probably fix the leg with pins and a cast without much debate over exactly how disabled the patient is.

2Viliam
Yeah, having or not having a gears model makes a big difference. If you have the model, you can observe each gear separately, for example look at a hurting hand and say how damaged are bones, ligaments, muscles, skin. If you don't have a gears model, then there is just something that made you pay attention to the entire thing, so in effect you kinda evaluate "how much this matches the thing I have in my mind". For example, speaking of intelligence, I have heard a theory that it is a combination of neuron speed and short term memory size. No idea whether this is correct or not, but using it as a thought experiment, suppose that it is true and one day we find out exactly how it works... maybe that day we will stop measuring IQ and start measuring neuron speed and short term memory size separately. Perhaps instead of giving people a test, we will measure the neuron speed directly using some device. We will find people who are exceptionally high at one of these things and low at the other, and observing them will allow us to even better understand how this all works. (Why haven't we found such people already, e.g. using factor analysis? Maybe they are rare in nature, because the two things strongly correlate. Or maybe it is very difficult to distinguish them by looking at the outputs.) Similarly, a gears model might split the diagnosis of ADHD into three separate numbers, and autism into seven. (Numbers completely made up.) Until then, we only have one number representing the "general weirdness in this direction". Or a boolean representing "this person seems weird".

A large fraction of the ITAR list.

How confident are you that it is possible to differentiate something significant (vomiting) from something that should be delayed? Is it hard to differentiate between different types of cries?

3jefftk
I can distinguish a few different cries, at least with my own kids. With Nora (15m) right now the two clearest are a complaining half-asleep cry where she's very likely to go back to sleep on her own if I leave her and pain cries which are very different and much more urgent feeling. With the older two (6y and 8y) there's again a pretty big difference between "I'm objecting" cries (I didn't get my way in a game, my sister pushed me, etc) and "I'm in real pain and want help" cries (fell down badly, stubbed toe, etc).

Many widely-known organizations in this field have publicly-identifiable persons and assets that can be pursued if they fail to follow through on their promises. For example, in the United States of America, the Internal Revenue Service requires some organizations to complete Form 990, which can be viewed by everyone.

Are there plans to provide a similar level of assurance to people who are interested in this cause?

Also, for people in the United States, consider running the hot water from a nearby faucet until the hot water is hot. Then, turn off the faucet and turn on the dishwasher.

As always, check your dishwasher's manual for specific recommendations.

Would the costs of figuring that out and implementing it exceed the expected benefits? Assuming that everyone in the household is already boosted with the monovalent version, it seems unlike for the costs to be worthwhile.

2tkpwaeub
I doubt it would cost very much. Epidemiologists have software they can use to model it. Moreover, an easy way to do controlled experiments would be dorm assignments on college campuses. At any rate, my unabashedly Bayesian gut feeling is that it's obviously a good idea to do it. See above for my priors. To the extent that this kind of thing is hard, I'd put it squarely in the "hard but worth it" bucket, along the lines of JFK's speech at Rice University. I'm calling for us to stop meekly accepting case surges as inevitable, and I don't think it's unreasonable to speculate that by leading with mass vaccination, we've unwittingly created a kind of "bang bang control system" with similar issues to overworked thermostats - a public health analog of metal fatigue, if you will.

The note about being under specified sounds like the article "They Write the Right Stuff". In the article, the writer describes the exacting process used to make software for the Space Shuttle.

What is the expects benefit of each additional hour of sleep? What is the QALY cost of a mattress as it ages?

1stavros
(Apologies in advance if any/all of this is obvious to you) Too much sleep is bad, too little sleep is bad. Sleep needs vary per person and throughout life but generally >6 hours, <9 hours is the range. You don't really sleep in 'hours', you sleep in cycles (https://en.wikipedia.org/wiki/Sleep_cycle) so measuring based on hours doesn't work so much. If you wake up naturally sometime in that 6-9 hour window, and you sleep deeply through the night (smartwatches are good at measuring this), you're probably getting enough sleep. If you have reason to be concerned about your sleep, consider getting a sleep study done. The benefits of more sleep are less relevant than the downsides of not enough sleep - chronic sleep deprivation is very, very bad. If your mattress is noticeably uncomfortable, it sounds like you need a new mattress :)

Thanks for quoting the bit about Elua at the end. It is helpful to remember that despite Moloch, et al, humanity has managed some pretty impressive feats, even in the present day.

It's easy to think that the counterexample of science in earlier posts is something accomplished "Once upon a time in a land far away."

Seconding UpToDate as a starting point and treating it like Wikipedia by using it as a source of references.

Then, you can use those references as a starting point in PubMed.

This suggestion is based mostly on watching my primary care physicians look things up at a major academic (university) medical center and conversations with physicians after using UpToDate + PubMed on my own.

Huh, that is very much not the experience I've had personally, or that people I've spoke with have had.

Context: I'm in America. Well I'm not sure how well they really do have it covered (hence my saying "Maybe, maybe not.").
