comicjk··on If you're just going to sit there doing nothing, at least do nothing correctly
I agree. The author's description of what is "reasonable" sounds like a blueprint for many of my late nights struggling with Windows:

"apps that assume that printing works will still behave in a reasonable manner: You’re just on a system that doesn’t have any printers and all attempts to install a printer are ineffective."

Maybe the underlying assumption is that the users will give up before spending an "unreasonable" amount of time on these tar pit features.

comicjk··on Sora: Creating video from text
If I understand trial law correctly, the rules of evidence already prohibit introducing a video at trial without proving where it came from (for example, testimony from a security guard that a given video came from a given security camera).

But social media has no rules of evidence. Already I see AI-generated images as illustrations on many conspiracy theory posts. People's resistance to believing images and videos from sketchy sources is going to have to increase very fast (especially for images and videos that they agree with).

comicjk··on The Journal of Universal Rejection
They don't sell the paper version directly, but you can get it in reams from any office supply store.
comicjk··on Common infections can spark psychiatric illnesses in children
There's also underfunded research on far-UV light, which at the right wavelengths kills pathogens without apparently affecting humans. It might really be that simple.

comicjk··on A clever “perpetual motion” device [video]
Was anyone else hoping it would detect the ball by simply completing a circuit (since the rails are metal and so is the ball)? Then it could give a magnetic tug after an appropriate time. Maybe this would be flaky because of the poor contact between rails and a rolling ball, but an inductive proximity sensor feels like overkill.
comicjk··on NYPD spent millions to contract with firm banned by Meta for fake profiles
Of course, slogans cannot be perfect. Slogans are tools for communication and should be judged as such. If "most people take it as" meaning something unhelpful, then it's defunct as a slogan. ("Black lives matter" is understood a lot more often, which is why it still works.)
comicjk··on Peter Shor's MIT Fall 2022 course lecture notes on quantum computing
An example of a textbook which starts from the discrete, linear-algebra form of QM (using the Stern-Gerlach spin experiment) is "Quantum Mechanics: A Paradigms Approach" by David McIntyre of Oregon State University. It's not quite like what's described here, but much closer to it than the more traditional way of teaching QM (using differential equations).
comicjk··on Is “do the needful” correct?
Google Ngram Viewer seems to agree, putting peak usage of "do the needful" in the mid-1800s. A phrase I would tend to use instead, "do what is needed", appears to be much more recent.

comicjk··on Commercial quantum computer identifies molecular candidate for better solar cell
I have long harbored an ambition of creating a Journal Of Implausible Chemistry, for the publication of research on hydrogen chains and other molecules cruelly disallowed by our impoverished reality.
comicjk··on Alphabet Announces Second Quarter 2023 Results [pdf]
US inflation YoY was 3% as of the most recent data. https://ycharts.com/indicators/us_consumer_price_index_yoy
comicjk··on An annual physical exam costs $400 USD on average in the USA
The insurance company pays, but what they pay is not this price. US medical care is littered with dummy sticker prices that exist to give insurance company negotiators something to do besides negotiate good rates. https://www.propublica.org/article/why-your-health-insurer-d...
comicjk··on Getting to know the right people (2022)
Your original comment didn't say that the notes contained insults and planned lies (beyond the dishonest appearance of spontaneity). Is this sample an exaggeration? It certainly looks a lot worse this way.
comicjk··on World’s oceans at record high temperature for 80 consecutive days
This is a classic math pitfall, described by mathematician Jordan Ellenberg as "Don’t talk about percentages of numbers when the numbers might be negative" because they're more often confusing than illuminating.

comicjk··on The death of self-driving cars is greatly exaggerated
I think you're right, though I don't think it's so obvious when it's being specifically compared with US COVID deaths.
comicjk··on The death of self-driving cars is greatly exaggerated
Where are you getting that death number? I'm seeing numbers around 43k, 30 times lower. Is your figure including health damage from air pollution or something? Or is it an aggregate over many years?

comicjk··on Vectorization: Introduction
They're not wrong answers, they're floating-point answers. What's wrong is the assumption that infinite precision will fit in a handful of bytes.
comicjk··on Germany Falls into Recession
There is a correlation. Germany has the reputation of being very concerned with inflation, which happens when the amount of money in circulation grows relative to the supply of goods to buy. When there is a supply shock (such as this energy conflict), inflation is the natural result, but a concerned government can respond by increasing interest rates to reduce the amount of money in circulation. That way they get less inflation than they would have otherwise, at the cost of slowing down the economy.
comicjk··on The Structure of Scientific Revolutions [pdf]
They didn't ask what books both men had read - I suspect Gore has read at least a large chunk of the Bible (he still describes himself as a Baptist to this day). It's just not his favorite book.
comicjk··on For chemists, the AI revolution has yet to happen
An example of what makes this so difficult is the "activity cliffs" often found in drug development: many pairs of apparently similar molecules will have totally different activity against a target protein. These differences can be understood if examined with costly physics-based simulations, but they have so far shown few of the simpler, compressible patterns that make machine learning effective.
comicjk··on Pytz: The Fastest Footgun in the West (2018)
I was baffled when I first entered my schedule for a conference into Google Maps, only to find when I flew across the country that all the times were wrong. I understand that it's a reasonable choice to use the local time zone at event creation, but it sure wasn't what I expected (I vaguely thought it would be like your alarm clock example, where it would move with the local time).
comicjk··on Scientific knowledge is drowning in a flood of research
I see this model of science as potentially misleading. One obvious reaction to the "too many bricks" idea is to try to put together some grand theory yourself (an "edifice"), but this nearly always means becoming a crank. Likewise, I don't think see how a scientist has ever been stopped by the mere existence of too much trivial research, though they might be diverted from better work by the need to produce mediocre work quickly. I prefer Hamming's questions: "What are the most important problems in your field?" followed by "Why aren't you working on them?"
comicjk··on PaLM 2 Technical Report [pdf]
Nonprofit status makes it much harder to extract large profits. A charity founder can pay himself a million-dollar salary, but he can't sell his shares in the nonprofit and become a billionaire.
comicjk··on Vitamin K2 supplements fail to slow calcium buildup in heart
The question in this trial was: Will people in this at-risk population have less calcium buildup in the heart if we give them vitamin K2? The answer was, on average, no. That's the key piece of information for public health.

Blood tests would tell us if the randomization ended with the two groups being very different, but the prior probability of that is small. Blood tests would also tell us if there is some subgroup that benefits more from the treatment, but with an increased risk of getting the answer wrong due to smaller sample sizes, which would lead to worse public health decisions.

comicjk··on Vitamin K2 supplements fail to slow calcium buildup in heart
This is a randomized trial with hundreds of subjects. The two groups should be statistically similar to each other in their magnesium levels (and other attributes). That's the purpose of randomization: so you don't have to find and control for confounders afterwards like you do in a non-randomized trial. It's easy to obscure or reverse a result by controlling for the wrong variables, for some examples see https://slatestarcodex.com/2019/06/24/you-need-more-confound...
comicjk··on Vitamin K2 supplements fail to slow calcium buildup in heart
If the proposed intervention is giving a pill, it seems fair to test that instead of a proxy. The study had hundreds of people; if the effect were big enough to be clinically significant they hopefully would have detected it, even with some patients failing to take the pills.
comicjk··on Five Books: The best books on everything
There is a deeper story. The realistic technical details are the bones; the flesh is the relationships between two human civilizations and a less-advanced alien race that doesn't know humans exist.
comicjk··on Five Books: The best books on everything
I think A Deepness In The Sky is actually better, especially for people on here. The story takes place on spaceships thousands of years in the future, but the characters are still using code based on Unix timestamps, and still complaining about legacy software.
comicjk··on U.S. regulator set to take over First Republic
You call passing a bill through Congress "immediate", and you think it can be "undone quickly"? I think the long-term budget deficit is too high, but the budget process is not responsive enough to be used to control inflation. (It's also too slow and clumsy when used the other way, as fiscal stimulus.)

One way of using the deficit deliberately as an economic control dial would be for Congress to grant the Federal Reserve the authority to adjust payroll tax rates within a given range. I doubt this could ever happen politically, though.

comicjk··on Former Hiroshima Branch of the Bank of Japan
There were some small Alaskan islands that Japan actually seized. The non-military population of Alaska in 1941 was tiny, about 73k, and land links to the lower 48 were weak, so isolating and occupying the territory by sea might have worked. The same goes for at least the smaller Hawaiian islands. The Philippines were successfully occupied despite a much larger population.

Regarding Asia, I think "to acquire territory" is not the real question. Most Americans today would say that we should assist staunch allies such as South Korea if they were invaded, without any desire to acquire their territory. That goes more for the Philippines in 1941, since the US had given them a 10-year security guarantee under the 1934 Philippine Independence Act.

comicjk··on Former Hiroshima Branch of the Bank of Japan
The point of the police in a society is that they have a near-monopoly on armed force, and therefore criminals can't hope to win by escalation. In a world where the US has by far the biggest military, it can to some extent arrogate to itself the role of a police force, which raises the issues you suggest.

WW2 is not this situation, and it's an anachronism to analyze it as such. Pearl Harbor was followed by a string of other US defeats. For a while, it looked like Japan would set up an empire from Alaska to Australia. You don't have the luxury of deciding to hold back in a situation where all your efforts might not be enough.
