The original poster had it right - you are mistakenly thinking that the block time is 20 minutes when it's 10. Once you make that correction, you are both correct.

Good summary, but the difference was only that they would have burned 45% more extra calories from their exercise had they not reduced their other activities. If this is the same in humans, then you would just want to multiply your extra ca

Okay, I don't study this, but I don't think that's what "cryptographically secure pseudo-random number generator" means. Not all things vaguely related to cryptography are required a CSPRNG and these answers are not

Wow, that brings back memories. The company behind that, Euclideon, is apparently now in the "hologram" business. Watch their video, it's exactly what you would expect from their earlier ones: https://www.youtube.c

It's the single largest source of such funding in the US (and I imagine in the world, too), yes. I don't know that it's >50% though, but it's certainly a large fraction. For example, it's budget is 4 times that o

While they could be drawn similarly to how Wang tiles are drawn, they definitely lack the aperiodicity property of Wang tiles. (Eg there are tiles with all four edges the same, hence you could tile the plain with nothing but that tile.) Of

It depends on what you count as "energy in". A solar panel produces more energy out than it takes in - if you don't count the sunlight as "energy in." A fusion reactor (hopefully) produces more energy out than energ

Admittedly, GoPro does actually have a lens distortion going on so that it can be wide angled. It actually makes it look more globe like than it is, as you can see from numerous sky diving videos. In them you can see this distortion by noti

intext:MYSEARCHTERM is what Google taught a few years ago when they had a "google poweruser web course" thing. My understanding is that these days it either doesn't work consistently or makes Google think you're a spambo

I read this comment before reading the article and got excited to read an article showing how the "establishment" was wrong. Much to my surprise, the article was saying the exact opposite! I'm still not really sure how to rea

The article says that MS (like everyone else) expects there to be fewer and fewer "fixed-function" features in a GPU with more shifting over to software-defined shader code. But isn't this just an introduction of more fixed-f

I was one of those downvoters because your comment adds nothing but pretends to be very insightful. You aren't actually computing likelihoods and multiplying them together, you're just pretending to. Bayes' theorem says we re

The point is that the vendor was claiming they had patched the flaw. They can't simultaneously claim to have a patch and that they know the patch doesn't fix it.

I agree with you - I can't pick any sense out of this paper. Note that they have not given a single example of a curve that is not a "fractal" by their definition. What would such a curve look like? A straight line is the o

Absolutely something I was thinking, but not sure what the right terminology is! "Microlens" sounds fancier than you need, I'm really happy to just diffuse it but with a limited blur so that they don't bleed.

I believe that this [1] is the oldest thread in HN about Theranos. There are two sub-threads that are negative and one which seems quite spot-on in hindsight. But the top comments are all quite positive. [1] https://news.ycombin

It seems like there should be a middle ground where you blur enough to remove SDE but not enough so that pixels overlap. The whole problem with SDE is that there is a perceptible gap between pixels - blur will spread the pixel over the gap

This seems like a dumb question, but why is it that SDE (screen door effect) is dependent upon resolution? It seems to me like extremely high resolutions would force SDE to be solved but that SDE could also be solved by making "fatter&
