Comment There are SERIOUS issues that make drones insecure (Score 1) 74

Quoting the parent comment: "You aren't even a little bit clever and you clearly don't know enough about the state of drones to start making bullshit claims about making it crash."

There is a huge social cost to being disrespectful.

Also, there are SERIOUS issues that make drones insecure. The comment just above this one lists some of them. Others:

1) RFI, Radio Frequency Interference: Someone is outside on the street welding something using an electric welder. Electric welding generates interference on ALL frequencies. The drone receives nothing but noise.

It is not necessary to list some of the places a drone should not land.

2) Drone lands, dog jumps out of the bushes and tackles the drone. Dog thinks someone has thrown an extra large frisbee. Or, dog has been trained to attack all intruders. Drone is damaged beyond repair.

3) It's rare, it happens maybe only once or twice a day, but sometimes there are HUGE gusts of wind. A crash into a tree could result in a drone dropping to the ground and killing someone.

4) Someone shoots at a drone with a BB gun. Drone crashes.

Many more issues have not been considered.

As in if someone anonymously puts up a poster on private land that defames you, you actually get to challenge it in court and if it's found to be libel it's taken down.

Uh, no. Not even close to how it works in reality.

If I put up a poster in my front yard (in the United States) defaming a Japanese doctor, a Japanese court has zero ability to make me take it down.

Look at this from a less "I personally approve of this ruling" angle - If a Saudi court rules that the New York Times needs to recall an issue for an offensive cartoon, would you expect the NYT to actually round up every printed copy in the US, or just to stop the delivery of that day's issue to Saudi addresses?

Submission + - Being Overweight Reduces Dementia Risk (bbc.com)

jones_supa writes: Being overweight cuts the risk of dementia, according to the largest and most precise investigation into the relationship. The researchers were surprised by the findings, which run contrary to current health advice. The team at Oxon Epidemiology and the London School of Hygiene and Tropical Medicine analysed medical records from 2 million people aged 55 on average, for up to two decades. Their most conservative analysis showed underweight people had a 39% greater risk of dementia compared with being a normal healthy weight. But those who were overweight had an 18% reduction in dementia, and the figure was 24% reduction for the obese. Any explanation for the protective effect is distinctly lacking. There are some ideas that vitamin D and E deficiencies contribute to dementia and they may be less common in those eating more. Be it any way, let's still not forget that heart disease, stroke, diabetes, some cancers and other diseases are all linked to a bigger waistline. Maybe being slightly overweight is the optimum to strike, if the recent study is to be followed.

Speaking of low-flow toilets I installed a high quality (recommended by Consumer Reports) low flow dual flush mode toilet two years ago and it's only plugged once in all that time. The older normal toilet it replaced used to plug weekly. So the problem with most low flow toilets is a matter of design, not the concept.

This seriously cannot end well. China already has a large arsenal of nuclear weapons, this goes so far beyond the scale of our pissing contest with Iran as to make it almost laughable (if it didn't potentially involve the world ending in a nuclear holocaust).

Submission + - Social Media Is Ruining Marriage for the Millennial Generation

HughPickens.com writes: Anthony D'Ambrosio writes at USA Today that marriage seems like a pretty simple concept — fall in love and share your life together. Our great grandparents did it, our grandparents followed suit, and for many of us, our parents did it as well. So why is marriage so difficult for the millennial generation? "You want to know why your grandmother and grandfather just celebrated their 60th wedding anniversary? Because they weren't scrolling through Instagram worrying about what John ate for dinner. They weren't on Facebook criticizing others. They weren't on vacation sending Snapchats to their friends." According to D'Ambrosio, we've developed relationships with things, not each other. "Ninety-five percent of the personal conversations you have on a daily basis occur through some type of technology. We've removed human emotion from our relationships, and we've replaced it colorful bubbles," writes D'Ambrosio. "We've forgotten how to communicate yet expect healthy marriages. How is it possible to grow and mature together if we barely speak?"

D'Ambrosio writes that another factor is that our desire for attention outweighs our desire to be loved and that social media has given everyone an opportunity to be famous. "Attention you couldn't dream of getting unless you were celebrity is now a selfie away. Post a picture, and thousands of strangers will like it. Wear less clothing, and guess what? More likes," writes D'Ambrosio. "If you want to love someone, stop seeking attention from everyone because you'll never be satisfied with the attention from one person." Finally D'Ambrosio says the loss of privacy has contributed to the demise of marriage. "We've invited strangers into our homes and brought them on dates with us. We've shown them our wardrobe, drove with them in our cars, and we even showed them our bathing suits," writes D'Ambrosio. "The world we live in today has put roadblocks in the way of getting there and living a happy life with someone. Some things are in our control, and unfortunately, others are not."

we live in the Surveillance Age now and will probably be for the rest of our lives.

Probably true - But I'll still use encryption for my private files and communications. I'll still refrain from screaming what I had for breakfast into the ether. I'll still make up random information when registering for any service that doesn't need real info to perform its core function. I'll still "fuzz" personal details when relevant to discussions on sites such as Slashdot. I'll still bait telemarketers even though they probably know more about me than I do. And, I'll still make Officer Twitchy get a warrant to search my phone, even if it means I get shot in the back trying to peacefully walk away.

Accepting the reality of something doesn't mean you should just give up - We all unavoidably die, why don't we all just commit suicide now and save ourselves the hassle of wasting all that time working and sleeping and exercising-so-we-can-live-longer and such? Sometimes, "accepting" something means "fight harder anyway".

And with this, we learn the real solution to the Fermi paradox - Not warlike tendencies among apex predators capable of becoming sentient, not resource starvation before getting off-planet (though close to that), not Reapers or something similar, not the actual absence of habitable planets - But simply the ease of developing ecosystem-destroying technology vs the complexity of understanding the chaotic interdependence of planet-sized ecosystems.

We had a nice run, humanity. Maybe the Blattarian race that succeeds us in a few million years will do better.

That's not how physics works. With a human contribution of 2.9 @/m2 and net imbalance when including natural forcings of 0.6W/m2, the natural system already has balanced all but 0.6W/M2 of our 2.9W/m2 contribution at current temps.

I think it is you who doesn't understand how physics works. The energy imbalance is a function of the change in forcing over time (dF/dT), not the forcing itself. If forcing didn't change the energy imbalance would be zero. That the energy imbalance isn't changing is just evidence that forcing continues to increase due to the anthropogenic rise in greenhouse gases in the atmosphere.

Ask Slashdot: How To Introduce a 7-Year-Old To Programming? 315

THE_WELL_HUNG_OYSTER writes I'm a professional programmer and have been programming since I was a small boy. I want to introduce this to my 7-year-son but know nothing about teaching this to children. Since he enjoys Roblox and Minecraft very much, and knows how to use computers already, I suspect teaching him to write his own small games would be a good starting point. I'm aware of lists like this one, but it's quite overwhelming. There are so many choices that I am overwhelmed where to start. Anyone in the Slashdot in the community have recent hands-on experience with such tools/systems that he/she would recommend?

What are these measurements you think are inputs to climate models? It's certainly not temperature measurements or precipitation measurements or wind measurements.

It sounds to me like you badly misunderstand how climate models work. As much as possible they are physical models. That is they model the actual physics that combine to produce our climate. Measurements of the actual climate are only useful as something to compare model output against.

Submission + - The 'Page 63' Backdoor to Elliptic Curve Cryptography 3

CRYPTIS writes: The security of Elliptic curve cryptography is facilitated by the perceived 'hard' problem of cracking the Discrete Logarithm Problem (DLP) for any given curve. Historically, for FIPS (Federal Information Processing Standards) compliance it was required that your curves conformed to the FIPS186-2 document located at http://csrc.nist.gov/publicati... . Page 63 of this specifies that the 'a' and 'b' elliptic curve domain parameters should conform to the mathematical requirement of c*b^2 = a^3 (mod p).

Interestingly, back in 1982, A. M. Odlyzko, of AT & T Bell Laboratories, published a document entitled “Discrete logarithms in finite fields and their cryptographic significance” ( http://www.dtc.umn.edu/~odlyzk... ). Page 63 of this document presents a weak form of the DLP, namely a^3 = b^2*c (mod p).

It seems then, that the National Institute of Standards and Technology (NIST), driven in turn by the NSA, have required that compliant curves have this potentially weak form of the DLP built in; merely transposing the layout of the formula in order to obtain what little obfuscation is available with such a short piece of text.
