Comment Re:Overkill (Score 1) 112

Most people probably haven't experienced total darkness. I experienced it while working late at a campsite (astronomy camp). I had to walk from the lab to my cabin on a moonless night with thick fog, no lights. You literally cannot see your hand in front of your face. You can't even tell if your eyes are open or closed. It was one of those epiphany moments where you're experiencing something completely new for the first time in your life. I remember thinking, wow, so this is what it's like to be blind. I had to find my way back to the cabin entirely by feel and my memory of the path.

Anyway, a mask or bag over your head isn't going to cut it. Even the photographic dark rooms I've been in always had a faint glimmer of light leaking in somewhere - a point of reference that told me which way I was facing. Fortunately the walk back to my cabin was downhill with grass on the edges of the path so I could tell I was sort of going in the right way. I don't think I would've made it if it had been completely flat and all grass.

Comment Re:Upscaling is BS (Score 1) 104

Are you basically saying to make pixels by averaging the color of the adjacent ones?

No, he isn't.

If its surprising to you that its possible to do better prediction of the missing information between the pixels of images than various kinds of interpolations (such as bilinear (aka "averaging" for 2x), bicubic, etc..), then its because you are wholly ignorant on the subject. Amazing that you jumped in to discuss a subject that you are wholly ignorant on.

If it were purely random data then your from-ignorance consideration of the subject would have some weight, but it isn't arbitrary data. Nobody spends their time looking at images of random data. The images we capture with photographic equipment have high degrees of coherence between neighboring scales (because thats the way the universe is,) and that necessarily includes the scales just above the Nyquist frequency.

Nobody is suggesting red dwarfs "enhance!" is possible, but a bit of upscaling can be done a lot better than simple interpolations.

Comment Controlled vs uncontrolled course (Score 1) 58

On the other hand, the factory has the ability to 'control the course' much better and shouldn't have to worry about drunk workers on the floor doing stupid tricks. They can also do things like embed direction lines in the floor(or even the ceiling), so the pathing is simpler.

And seriously, they carted him to the ER? It was within golf cart distance? Or was that just an inappropriate choice of words? Maybe the problem isn't limited to the golf crowd at your job...

It's a known turn of phrase at least in American English. 'Hauled off' would have also worked, 'carted off' tends to imply an ambulance to me. IE he was treated as cargo. Then again - being carried off a sporting field after injury seems appropriate:


There's a fairly good chance that he was indeed carted off, at least initially - by another golf cart.

Comment Re: Hypothesis: Patch the good eye (Score 1) 112

Decades ago one of my sisters had a lazy eye. She had to wear an eye patch on the good eye for a while, that's all. Simple solution that doesn't interfere much with their daily lives.

Fixes a decent percentage of the population, sure, but what about those for which the eyepatch fails?

They simply don't trust a cyclist, who doesn't have at least one foot firmly on the ground, to not pedal out in front of them.

Odd, drivers tend to have that view of me even when I have both feet on the ground straddling my bike, looking at my phone.

I mean, I'm wearing a helmet*, but I'm not in 'racer' gear otherwise.

*Mainly because I've managed to use a bicycle helmet up. I like my skull.

Thus why he said that driving through a deactivated school zone slowly is being an 'assbag'. Because he's not only going slow, he's slowing down everybody behind them.

Look, here in the states residential streets are typically already 25mph - the speed limit for most school zones. Most schools only abut against 1-2 higher speed streets. Get the kids over them safely, the rest of their trip is on 25mph residential streets where kids are to be expected.

We just don't feel the need to keep the speed limit lower when kids are unlikely to be present. Thus the systems of lights. Your system of permanent speeds in this situation is fine, and easier for self-driving cars to handle, but that's not the case in most of the USA and Europe.

Comment 55mph speedlimit = politics. (Score 1) 401

It normally amounts to political. People drive what they feel is safe, normally speaking.

More in depth reasons vary - impressions of safety*, noise abatement(doesn't work if not followed), the idea that increasing the speed limit will increase speed on the road(it normally doesn't), even revenue generation - the cops get to write 20+ over tickets rather than 10+ over, and the former is a much bigger fine. etc...

*Despite evidence being that speed limits that are too low are almost/more as dangerous as too high, because they tend to increase speed differentials.

FTA - "Despite the awkward encounter, the cyclist didn’t leave with a negative impression of self-driving cars."

Imagine that, somebody driving a fixie who understands testing! That "The two guys inside were laughing and punching stuff into a laptop." means that, yes, they have a sense of humor and the absurd, but are punching stuff into a laptop, presumably to log additional information in for that encounter.

With this incident added to the list, the programmers can now develop a module to handle this behavior appropriately.

I get irked when a problem is encountered in a test and used to imply that the whole idea is stupid. This article isn't too bad, demonstrates WHY they're still doing testing.

I think that it's that he's willing to use himself as a test subject before inflicting it on others, fairly rare today.

Not that I suggest a heart surgeon do a transplant on himself or that a doctor inject himself with insulin if he's not diabetic...

But living in complete darkness for ~5 days can have unexpected developments/difficulties, it's probably best to NOT inflict that on kids until you know what to look for.

Comment Re:Economics isnt science. (Score 1) 141

Personally, I think that people are incorrect when they think of Marx as an economist. He wasn't. He was more of a socialogist. His economics were a side-note compared to the class struggle portion. It's just that you can't build a utopian social theory, like many philosophers have before, without touching upon economics. He was right that the social structures of the time were unsustainable though.

Comment Re:Something else economists could do... (Score 1) 141

That's a bit like trying to predict the weather by looking outside right this moment and forecasting it'll be the same tomorrow though. You observe the people, develop a model that attempts to predict their actions, then use the model to attempt to predict future actions, thus allowing you to make accurate forecasts.

Besides that, to misuse Asimov, predicting a human is hard. Predicting a group of humans is substantially easier.
