Comment Re:Weight (Score 1) 215

"Wind is a particular hazard, because drones weigh so little compared with regular planes."

Small drones don't have much inertia. They can be easily flipped by a small local wind gust. This is a big problem for drones that operate close to buildings, where there are eddies and turbulence as air hits the building. Pass the corner of a building and the wind situation may be completely different.

Very smart and aggressive stability control systems are able to overcome this. See this drone from PSI Tactical, which weighs about 0.5Kg and is supposed to be able to operate in winds up to 30MPH.

Comment Re:Sue police department, this is routine procedur (Score 1) 463

This particular officer probably didn't break any criminal law. You could argue "reckless driving", but reckless has a very specific meaning in law. The fact that the driver's vehicle continued in a straight line as the bike lane curved suggests that he wasn't any less careful than many people are on a regular basis. "Reckless" requires a wanton disregard, a level of carelessness well beyond what a reasonable person would do.

Nothing suggests he was reckless, but I'd say there's a pretty good case for criminal negligence which can also lead to a manslaughter charge. Unlike recklessness, negligence is a passive failure like not yielding, halting for a red light or in this case, failing to keep your car in your lane. They're duties you take on when you get a driver's license and operate a motor vehicle, just like a doctor can be sued for malpractice for missing obvious clues about what's wrong with you. You can't just run people over and say "Whoops sorry, it was an accident" and get away with it.

Comment Yes, we know that. (Score 4, Informative) 245

Battery storage for bulk power has been talked up for years. Mostly by the wind industry. With solar power, you get peak power and peak air conditioning load around the same time. Wind varies about 4:1 over 24 hours, even when averaged across big areas (California or the eastern seaboard). So the wind guys desperately need to store power generated at 4AM, when it's nearly worthless, so they can resell at 2PM. When the wind farm companies start installing batteries at their own expense, this will be a real technology.

With the US glut of natural gas, this isn't needed right now. Natural gas peaking plants aren't all that expensive to build, and make money even if they only run for maybe 6 hours a day. That covers most peak needs.

There are other ways to store energy. Some of the dams of the California Water Project have reversible turbines, which can run either as pumps or generators. They pump water uphill at night, when power is cheap, and let it down during the afternoon to generate power. Since the dams and pumps are needed for water handling anyway, this adds little cost.

Nobody else would get away with breaking the law because they were following orders. You try telling that story in court when you run somebody over because your boss wants every email replied to within five minutes and they'll put you behind bars in an instant. If you want to make this sting upwards in the system, do that. But don't pretend he shouldn't be prosecuted to the full extent of the law.

Comment Why? Nobody uses NFC payments (Score 1) 187

A few years ago, those Google NFC payment terminals were all over Silicon Valley. Nobody used them. Newer credit card terminals show no sign of supporting them, although some apparently have the hardware inside for it.

Another problem is that if the technology just requires the phone's presence, not interaction on the phone, it's insecure. "Near field communication" is only supposed to be up to 20cm, but a 2013 paper at Black Hat demonstrated connectivity at 100cm, which is good enough for crime. If it does require interaction on the phone, the user has to activate the phone, navigate to some app, and deal with the app. This is slower than swiping a credit card.

It's easier to do than card-reader skimmers.

Comment Same thing from ultra-orthodox Jews. (Score 4, Informative) 542

Many ultra-orthodox rabbis who demand their followers not use uncensored smartphones or uncensored internet access. In 2012, a big anti-Internet rally for ultra-orthodox Jews was held in New York. "The siren song of the Internet entices us! It brings out the worst of us!" The event was streamed live and is summarized on YouTube.

There are ultra-orthodox ISPs with filtering. The filtering is very stringent, based on a rabbi-approved whitelist. "That's all you get, and nothing else."

There are kosher cell phones. "Kosher Phone has no camera, no Bluetooth capabilities, no memory card slot and cannot be connected to a computer."

That's in the US. In Israel, kosher cell phones are so locked down that only approved numbers can be called. Even rape crisis centers are blocked.

The only reason SLS exists is to keep the congresscritters from the former shuttle supply chain districts happy. That's it.

Right. NASA also still has way too many "centers". Ames (except for the big wind tunnel) and Glenn (except for the test facilities at Sandusky) ought to go.

Comment Not detecting potholes? (Score 2) 289

Google isn't detecting potholes? Back in 1985, we had that on our DARPA Grand Challenge vehicle. The LIDAR on top of the vehicle was generating a ground profile. This was for off-road driving, where that's essential. I'd assumed Google was doing that; they have a Velodyne laser scanner that provides enough information.

In traffic, sometimes you can't see a pothole because it's obscured by a vehicle ahead, but if the vehicle ahead doesn't change speed, direction, or attitude, it's probably safe to proceed over the ground it just covered. On high speed roads, you can't see distant potholes clearly because the angle is unfavorable, but if the road ahead looks like the near road, and the near road profiles OK with the LIDAR, the far road is probably good. That's what the Stanford team used to out-drive their LIDAR range. (We didn't do that and were limited to 17MPH).

Fixed road components should be handleable. People, bicycles, and animals are tough.

Comment Re:Better Idea (Score 1) 64

But you can't then just leave the printed document in the tray. That's not secure. You need to have a shredding module attached so that after the email is sent the original can be destroyed.

Well, maybe, but neither the sender nor the recipient knows anything about the various other addresses that have received a copy of the document, plus information on the send/receive times.

It's not clear how any of this could be made secure to either party's satisfaction. If the printer can decode the document and make a legible copy, it can also forward the electronic version of that copy (and/or the decoding keys) to a third party.

Comment Talking to "different" people is bad for you (Score 3, Informative) 76

This is fascinating. It's not the classic "people don't have social lives in the real world because they are on line too much" argument. The authors argue that following people who are "different" from you is bad for you. They write:

"Compared to face-to-face interactions, online networks allow users to silently observe the opinions and behaviors of an immensely wider share of their fellow citizens. The psychological literature has shown that most people tend to overestimate the extent to which their beliefs or opinions are typical of those of others. There is a tendency for people to assume that their own opinions, beliefs, preferences, values, and habits are âoenormalâ and that others also think the same way that they do. This cognitive bias leads to the perception of a consensus that does not exist, or a 'false consensus' (Gamba, 2013)."

"The more people used Facebook at one time point, the worse they felt afterwards; the more they used Facebook over two weeks, the more their life satisfaction levels declined over time. The effects found by the authors were not moderated by the size of people's Facebook networks, their perceived supportiveness, motivation for using Facebook, gender, loneliness, self-esteem, or depression, thus suggesting the existence of a direct link between SNSs' use and subjective well-being."

This is a new result, and needs confirmation. Are homogeneous societies happier ones? Should that be replicated on line? Should efforts be made in Facebook to keep people from having "different" friends?

Comment Re:"Moderation?" Don't you mean "Censorship?" (Score 1) 76

Call me cynical, but I just don't see Facebook adopting a sane moderation system, like for example anything that approximates slashcode. Their equivalent of "moderation" would better resemble censorship. They would simply hide the thoughts and comments they don't think you would like. Of course, it would be for your own good...

It's likely that a portion of the story is something that we also see here on /.: None of them really support anything that might be called a true "discussion". The reason both here and FB and the other "social media" is the approach of having a running string of "latest" topics, which quickly scroll off the bottom and out of sight. If you don't happen to see a thread in the first hour or so, you generally won't ever see it, and won't contribute to it. So, except for a few rabid topics like religion or partisan politics, where a small group can have fun running it out to thousands of rephrasings of each person's personal views, most discussion threads are typically shallow, and peter out at a depth in the single digits.

I've talked to a number of people here who express disappointment at how shallow the /. discussions usually are. They start of hoping to find in-depth analyses that point them to information that they hadn't run across or noticed. But they're disappointed with most of the threads, which only repeat a few things that those familiar with the topic already know, and then the threads just stop.

FB is quite a lot worse this way than /., of course. I've been on it for some years, and I've never noticed a "discussion" that got to depth greater than 3. I'm sure they exist; I've just never seen them. And a lot of my friends are quite well-informed "geeks" who in person can engage in long discussions. Why don't they do this on FB? Well, they may try, but quickly learn that few people ever read, much less reply to, their comments. Over here, we do sometimes get a bit deeper than that, and I've seen a lot of good information here at depth 5 or 6. But still, that's not very deep as discussions go.

I've seen much better (i.e., deeper and more informative) discussions on nearly every mailing list I've been on. If you want actual informative, socially interactive discussions, that's a noticeably better model for a forum's structure.

But the "social media" is primarily just an electronic form of the old "see and be seen" sort of social event. Such things have always been known as shallow and uninformative, although they can be fun if populated by the right crowd.

Comment Re: 5820K is an extremely nice part (Score 2) 181

Yes but X99 and DDR4 blows any chance of doing Haswell-E on a budget. I need a new PC and is considering either 4790K or 5960X, the former is fine now while the latter is going all out on new tech which I hope will last longer. Eight cores crushes the mainstream chip in multithreading. Eight RAM slots in case I want to double up, of a type that will exist long and improve much. Plenty PCIe lanes. Slightly weak single threaded performance at stock but considerable overclocking potential. With 10% performance improvement per generation it'll take ages until I need an upgrade again. On the other hand, a 4790K might last me long too.
