It's not good. If it were good, it wouldn't juxtapose random uncited numbers together that don't compute: > Crop yields increase 3-5× > Farmers go from $600/acre to $14,000/acre revenue 5×$600 is $3000. Where

That is... not what your link says at all. Rather the opposite: > Fatal atherosclerotic events were more common in the control group (70 v. 48; p<0.05). However, total mortality was similar in the two groups: 178 controls v. 174 expe

Are you claiming humans would fail an ABX test between a 60Hz and a 120Hz monitor? That sounds like a pretty extraordinary claim.

You are misunderstanding. The bloom filter is only a preliminary check; if it indicates a revoked certificate, you then verify that it's a true positive the traditional way.

OP called out "skyscrapers". What counts as the precise cutoff for "tall buildings" is always going to be a matter of opinion. But I live in Cambridge, MA and I can assure you Somerville would remain one of the densest c

LA has an order of magnitude more population than is required for functioning public transit. But you're right they don't have the density. The key is to realize the cars themselves killed density . Parking lots, parking spaces,

I still remember the day I found out the "98.6 degrees" human body temperature was just an oversignificant conversion from "about 37 C, or maybe lower."

This is an incredibly easy problem to solve, relative to the current crisis: it only requires the federal government allocate enough money. There is some price per mask at which the N95 respirator manufacturers that currently exist in the U

Serious question: If the FBI and DHS are seizing PPE, where is it going? Why can't this hospital be a beneficiary of seized PPE, rather than an (almost) victim?

Higher education is merely one face of Cost Disease; we've seen similar trends in medical care, transportation (especially US subways), primary education... Slate Star Codex [1] has a good overview, but doesn't provide a solution

Two ideas come to mind: - You can create public pre-signed URLs with an unlimited expiration date using SigV2. I doubt SigV2 will stop working anytime soon. - Or, if you want the link to provide access to anyone, why not make the object pub

One way to accomplish this would be to nationalize companies instead of bailing them out, right? If the taxpaying public bears the risks of your business, why shouldn't it get to share in any of the rewards? I suspect the answer is som

jwz isn't a fan of this site. Last I checked, if the referer was news.ycombinator.com, it redirected to a testicle in an egg cup.

I wrote that it was `n-1` in my comment. Doesn't seem like much of a trick to me.

This doesn't sound much like a trick[0] question to me, it just takes working out a few examples by hand to guess that it's `n-1`, and the proof isn't hard either. And the result shouldn't be surprising: if sorting can b

Methane is a far more potent greenhouse gas, and it naturally degrades into CO2 in the atmosphere. Burning methane it on the ground, even not for energy, helps mitigate the warming effect, because it is that much more potent than CO2.

Were you able to measure the outcome of this process? I.e., was there a significant reduction in inconsistency, inaccuracy, or similarity bias after the exercise?
