I'd like to see more people being able to take self-study proctored exams, for those fields that can do it. There's a lot to be said for what is essentially a vo-tech education. It's purely objective and very useful.

That would leave a lot more space open in schools for creative work. That includes both academic research and the humanities, which are less objective but nonetheless valuable. As has been pointed out before, during the current health crisis, people turn to the arts: TV, books, podcasts, video games, etc. These are things that are hard to learn with self-study and impossible to test for -- except for the test of whether people will want to consume them.

Even programmers eventually need at least some of this. A development team requires a lot of people trained at a purely vo-tech, objective level to be experts in the various technologies. But for a product to be successful, it also requires people who know what its users want, which is much harder to judge objectively, and harder to learn from a book.

I believe too many programmers go to university to learn what they could learn on their own, or at a much less expensive school that doesn't try give a broad education. We need a lot of those, and employers make a mistake in rejecting people who don't have that university degree. Worse, even among those with that university degree, they test them purely on their objective skills, and then later complain that they produce ugly interfaces and write terribly.
Have my vote printed to a roll of paper, like a cashier's counter roll. Make sure that it shows through an opening in the case, so I can verify, and then rolls further (beyond the opening) so I cannot see it anymore. This is a way to store the votes "write only". The rolls are both human readable and machine readable (OCR is nothing new).

The only problem with this compared to voting forms is that form fall into the bin unordered, so it is harder to link a vote to a person.

Just an idea.

I would not trust ANY system that stores my vote on a re-writable storage medium. I know there are some crypto/blockchain tricks that may help, but that's so hard to audit for lay people that I prefer the paper roll any day.

I think Sidecar was the real admission that Microsoft was right, and it's more expensive and more limited than a detachable touch screen. If Apple made a Surface Book with macOS it would be superior to the iPad Pro in every way even if the software wasn't optimized for touch.
I wanted to clarify something. The parent poster wanted to know how the 25 million case number was arrived at. I just provided an example of how such a number might be arrived at. It is far too simplistic of a model though. I have also read there is confusion over the term “case”, as to whether it’s a hospital case vs total cases in general population.

Look, I'm all for affordable housing, but when viewing this within the context of a looming recession and potential financial crisis I can assure you that the last thing you want to do is add in a potential amplifier to a housing market crash. Houses may get cheaper, but everyone is going to suffer in very difficult to imagine ways. Corporate debt markets are looking scary as hell right now. If you threw a housing market meltdown at it right now, we could easily be looking at something much much worse than what we saw in '08.

I think there's an impression that cancer is one disease rather than an adjective used to describe at least 70,000 different diseases (if one wants to be pedantic). Even the biggest killers of those probably have a 1,000 researchers max.
I think I’m getting tripped by false positive, true positive.

A test with high sensitivity will have a low false positive rate.

A test with high specificity will have a low false negative.

So having a test with high sensitivity but low specificity will result in trust in the positives, but not trust in the negatives?

It may be bizarre. I grew up on traditional Chinese medicine in Taiwan. Vast majority I had was various types of plants like you mentioned in power, pellet, or pill form very similar to western medicine. There is some medicine extracted from animal products like musk, honey, etc, though much less used.

There are major efforts in Taiwan's universities to reinterpret TCM with contemporary science methodology. In term of manufacturing, the process is very far from the image of a "wet market". Acupuncture & Tuina, as part of TCM, have been applied on athletes around the world.

Due to my first hand account of TCM, I'm unable to dismiss TCM just as easily as you.

One thing I like to point out though, Taiwan's regulations on wild life and traditional medicine may be what China currently needs to curtail future potential outbreaks. As you know, TCM is tremendously popular in Taiwan yet Taiwan doesn't produce outbreaks like its neighbors does.
Ah man, 20 years too late for me!
That sounds an awful lot like a romanticized perfect democracy, which cannot exist outside of fiction, or a social credit system. There's an ongoing study on the effectiveness of a social credit system. It's happening in China. Go test it out and report back.
Something like that should come with a massive political cost - maybe after the crisis, all sitting politicians become ineligible for re-election on the basis that they shouldn’t have let it come to that point in the first place.
Only one clinical study has been published on chloroquine (by a French group), and the results are lackluster. No patient was cleared of virus after six days using hydroxychloroquine alone. A tiny fraction of patients were cleared in 4 days using an adjunct therapy (azithromycin). The study itself has issues, and it's not even clear whether it will clear peer review.

The President is doing something very dangerous here with his comments in the last two days.

By stoking chloroquine hype, he's setting the country up for a massive disappointment should the drug fail to produce treatment, or unexpected side effects.

Although the drug has been used in humans for decades to treat malaria, it has not been used to any extent on humans to treat COVID-19. There's a non-zero chance of adverse reactions, potentially serious given known problems with the chloroquines.

Even worse, the idea that a "treatment" exists will encourage people to let down their guard and will very likely lead to even worse outbreaks.

Unexpected things happen all the time in clinical trials. This is the main reason it costs billions to bring a drug to market. We can't predict jack squat.
I believe the demo query

SELECT DISTINCT ON (location) location, time, report
FROM weather_reports
ORDER BY location, time DESC;

could also be written with a self-join like so

SELECT location, time, report
FROM weather_reports
JOIN (
SELECT location, max(time) AS time
FROM weather_reports
GROUP BY location
) as _ USING (location, time)
ORDER BY location;

though I'd be curious what the query-plan differences are. I suspect the DISTINCT ON might translate more closely to a lateral join

SELECT
FROM (
SELECT DISTINCT(location)
FROM weather_reports
) AS locations
JOIN LATERAL (
SELECT location, time, report
FROM weather_reports
WHERE location = locations.location
ORDER BY ts DESC
LIMIT 1
) AS reports ON TRUE
ORDER BY location;

But I really can't say.
The problem with tests like the SAT is that on one hand they produce quantifiable results and the comparison of one student's score to another student's score is indeed objective, but that does not mean the test itself is an objective measure of performance.

The primary fault is that the SAT is essentially a form of convergent IQ test. A convergent test is a test of questions with the accepted answered defined before the test attempt and comparing the test takers answers to the defined answers. This is convergent, or coming together, in that performance is measured against subjective, subject based (inferred acceptance), criteria. I understand the SAT is intended to be used as a measure of general scholarly assessment, but its primarily used as a discriminatory filter to limit access to a preferential segment. As such it is essentially an arbitrary IQ test in practice regardless of its intentions.

In contrast IQ tests more generally preferred by the psychiatric community tend, almost exclusively, are divergent tests. A divergent test has questions without any prior identified answer and so there is not a simple right/wrong conclusion. Instead the tests generally seek out things like abstract reasoning, creativity, reasoning, answer diversity, and other aptitude performance criteria.

In the few psychiatric administered aptitude tests I have taken I generally test a bit below the genius level. If on a numeric IQ scale genius is 150 or 155 I would be below that at 140 to 150 depending on the test and test criteria. The SAT, on the other hand, rated me as outstanding a math and reasoning but otherwise barely literate. Those SAT scores are clearly at odds with my real world performance and other test results.

Confusing the potential for objectivity, such as comparing score results, to actual objectivity, such as whether the scores are a valid measure in the first place is a common error. The most common IQ test is the Stanford-Binet Test formed by Dr. Lewis Terman who made the same error:

The study from France seems to suck, though. Not very valuable data.

They measured virus, not outcomes, they measured virus in the throat, not the lungs, the starting point was not the start of the disease but some later (more arbitrary) point in time, the two groups were not randomly assigned and the study wasn’t really blind.

It could be that they just happened to compare two groups where the treatment group was further along in the illness – especially since they try to sell that as a disadvantage for them, but that could honestly be an advantage for them. We know that virus in the throat decreases as the illness progresses. (Virus in the lungs is much more relevant and also dangerous here, better would probably be outcomes.)

Not really evidence, sorry.
The straps will greatly aid a good fit once it's generally shaped for an individual's face. Also, a patent prevents others from profiting from making this and selling it, if they decided to enforce it, which would be unlikely unless it was egregious.

You're right, garbage vodka is garbage.

However the difference between a $20 bottle and a $45 bottle of vodka isn't that noticeable, especially when you consider the difference between equally priced tequila, whiskey or wine.
To be fair, I don't think that he's saying it should be banned -- he's saying that we need a lot more testing before claiming this is a cure based on one study with a tiny number of participants. His statement is accurate.

And the quinine derivatives have some very subtle neurological effects that last a lifetime. Suicidal ideations -- for life and incurable -- are a well known side effect of mefloquine at least. Maybe this one doesn't have those effects, I don't know -- but there's a really good argument to do a lot of testing before taking this in any other than an in-extremis situation.

I'd beg to differ on that. If the economy was left to crash, the cost of housing and rent could go down, which is the main expense for most households.

What the cash injections are doing is holding these high at all costs, transferring money to those who already have assets. The non owner classes will be poorer than ever, facing ever unaffordable housing with extra taxes to cover the bailout debt.

Instead of this. The government could decide that leases for the tax year 2020-2021 are getting their prices slashed 10% and there would be different consequences on the economy.

It's all largely driven by human decisions. The virus has no say in that.
I realize this is a best effort kind of thing so maybe these questions aren't in the scope but:

1. Is the intention that the mask be disinfected after wearing it?

2. In assembly instruction #5, it says "If you use a filter...". Why would someone use this without a filter?

3. Is there an advantage to this over buying a cartridge type construction mask?

Hate and shame are evolutionary mechanisms to get people to follow group norms. As long as they hurt (something you seem to accept), people will try to avoid them.

It’s also worth noting that these are mild measures compared to the other stick societies like to use, criminal law. If people felt confident that rapists were prosecuted not just in cases where their victims number in the dozens (Weinstein, Crosby), they wouldn’t feel the need to use social and economic pressure.

It's also nothing new: "In Ancient Greece the Athenians had a procedure known as "ostracism" in which all citizens could write a person's name on a shard of broken pottery (called ostraka) and place it in a large container in a public place. If an individual's name was written a sufficient number of times, he was "ostracized"—banished from the city for ten years. This was normally practiced against individuals who had behaved in some way that offended the community."

Wow, good memories. I was into Greenspun's writings, ArsDigita, AOLServer, OpenACS. Even managed OpenACS releases for while. Lots of good people there at that time, with concepts that only later became mainstream: application servers, database connection pooling, templating, user-registered tags, decent databases (mysql wasn't included in that list).

We ported the ArsDigita Community System to PostgreSQL, added a lot of features into it with the subsequent addition of .LRN, a learning-management system the Berklee School of Music funded IIRC, and many other things.

Aaron Schwartz, Ben Adida, Don Baccus, Michael Cleverly, and many many others besides myself (Roberto Mello) were contributors.

> If a mobile platform could guarantee secure voting

First, that's a mighty big if, and second, it's not enough!

Voting is a process where unlike online banking or online shopping there is no way for a human to go in and fix errors, there's no way to audit a vote and go "Oh, Bob meant to vote for A and Cindy meant to vote for B, so the machine did it wrong". It's not enough that an electronic voting system is correct, every single voter has to be able to trust the system, and for that it needs to be simple to understand.

You can't look at the electrons inside a silicon chip to determine they're doing the right thing. But with pen and paper and envelopes and urns and observers and counters, you can determine that the system is doing the right thing. Involving lots and lots of citizens in the voting system is not a bad thing, quite the opposite! You want as many eyes as possible on the entire process to ensure there's nothing shady going on, that there's no mistakes.

But if all the votes go into a black box that spits out the results, all of that goes away, all of that trust, all of that ability to verify that the results are correct.

Are you are talking about the study that was trendy yesterday? The control group is not randomized, and most of it was in others hospitals. They are not counting the 6 patients that they lost in the treatment group (1 just leave, 1 had too much nausea, 3 where transfer to ICU, 1 die). It is more strange that they didn't lost any patient in the control group.
