Basically now they can do a meta study on how the review process of IRB has flaws.
As shown, if you intentionally try to bypass the IRB, apparently you can. It's even reproducible.
I actually hacked something together like that and it surprisingly looks much better in a video than in real life.
I guess the main reason being that we have two eyes and the brain still realizes it is flat (which is weird because it doesn't look flat in a video).
It works well in the video because in that context we are trying to estimate depth relatively to the camera.
In real life, we are trying to estimate depth relative to us. In order to fool our brains we need both a very low latency and a high frame-rate. That was one of the major hurdles to solve for VR as well, leading to John Carmack's famous complaint that he can ping across the Atlantic and back faster than he can send a pixel from his desktop to his screen[0][1].
Anyway, back to the video: basically, when comparing 3D movement relative to the camera our brains seem to be more "forgiving".
From my experience living in Korea and the fact that Korea has one of the lowest productivity of all oecd countries, it is half-half.
A lot of the time is actually not "hard-working" but rather drizzling some work.
This is partly because you know it is expected that you stay long hours (and so you stay long hours without being explicitly asked) so you might as well just do your work slowly.
Also it is partly that nobody can work concentrated for such long hours.
And a lot of time is wasted by people not asking when they are stuck with any kind of problem / task (losing ones face / looking incompetent problem).
An RV is basically any bus-sized living space which has its own engine. They usually range from 20 feet to 40 feet, and frequently require the same restricted Class B driving license as a city bus.
I don't think that objection, by itself, invalidates the the video author's criticisms. According to Wikipedia, the hyperloop is intended to have a pressure of 100 Pa or 0.1 % of atmospheric pressure[1]. That is not much different from a prefect vacuum for the purposes of an approximate engineering calculation.
That's like saying there's no difference between 99.9℅ the speed of light and going all the way there, from an engineer perspective. Turns out, one of these requires an infinite more expenditure of energy than the other. Similarly, if you're evacuating a tube by removing gave the gas at a time, 1/1000 is attainable. 0? Not so much.
I don't disagree but that is not issue here. The issue is that for the purposes of discussing the mechanics of the tube like strength, seals, safety etc. the small amount of air left in the tube should not throw off simple calculations by too much.
No, the air in the tube matters, at least in Musk's original design, which has the pod running on a very thin air cushion. In practice, most designs are maglev, for which a hard vacuum is best.
That, and AFAIR original design had a system to pull the air from the front to the back, thus lowering the drag while reducing the need for lower air pressure.
There's no such thing as a 'full vacuum' in the real world. If you think that invalidates the arguments in the video then that likely means that you need to do more research on vacuum systems...
"The solution might be found in a form of constraint: more standardization of the time for work and the time for life."
And stuff gets even more crowded because everyone is free at the same time, yay.
Like a lot of sociological research, I don't think this was written with knowledge workers with hobbies and/or side projects in mind. Still, I found that statement deeply frustrating.
Most tap water in Germany is "recycled" water. I think this goes for most of Europe?
Drinking tap water and adding your on carbonate is even a thing here (German use the word as synonym for carbonated water).
"If anything, recycled wastewater is relatively sweet" - Said no tap water drinker ever
There are still worlds between the US and Europe..
Usually the recycled waste-water is send in to the rivers.
The fresh water usually comes from dams, ground water or river bank filtration (you don't suck out of the river, but from a well right next to it, so it get's filtered by the ground in between).
The water from the dams tastes really really good. The one from the big river (at least in my town) is very rich in minerals, not exactly the tastiest, but perfectly fine to drink too. The minerals build up in water cattle though and are annoying to clean off.
German tap-water is usually cleaner than german bottled water I think.
In the warmer parts of europe water is often is chlorinated I think, wouldn't want to drink it.
I didn't read the article, but I'd be afraid of purely recycled water. I know the fish have problems because of contraceptives, which are hard to filter out and in Great Britain there are traces of ataractics even in the ground water.
Not true - ground water accounts for 80% of Germany's drinking water, with reservoirs accounting for the rest. Germany has a very strong set of waste water treatment laws, but that treated water is either used commercially, for irrigation, or dumped into rivers and lakes, just like it is here in the US.
Before you get all high and mighty with your anti-americanism, check your facts.
Not sure what -he- meant with "There are still worlds between the US and Europe", but there are worlds between Germany and the parts of the US (large cities West and East coast) where I've been.
A lot of water has such a heavy chlorine smell and taste, I can't drink it - same goes for US soft drinks that are created with tap water, can't drink. There is practically no smell or taste in German tap water [0].
[0] I might be biased and not taste it any longer because of growing up here
Is it? I think most water here in Germany comes from a long-distance water supply that is filled with water from aquifers (which regenerate fast enough though).
Sure, the wastewater gets treated to be extremely clean, but I think it just gets pumped into rivers.
