then your nice RSA or AES encrypted data stream is (so the thinking goes) highly vulnerable to quantum cracking,
Actually, from what I read, symmetric encryption like AES is safe, it is the public key (RSA), which is used to transmit the symmetric key, that is at risk. So the hardware encryption is safe, you just need a software upgrade to improve the public key side if quantum computing ever gets close to cracking it.
Wrong. Quantum communication solves this problem. A quantum comm channel cannot be spied upon,
My understanding is that the quantam channel is difficult and low bandwidth, so only used for key exchange. Are you suggesting they can encrypt all my communications quantumly??
Wrong, and that is the point. "Man in the middle" is not possible with quantum communication. Either the signal stream is lost, or delayed.
Nah. Your quantum endpoint is the man in the middle. I'm talking about the specific case where you have no authentication, remember?
Article seems like nonsense to me. We already have secure transmission by end-to-end encryption. Securing the transmission channel further will do nothing to enhance that, and nothing to stop the hacking mentioned in the article.
What possible use is quantum key distribution? If you can authenticate, you already have secure key distribution, and if not, you are still vulnerable to man-in-the-middle, no?
Species are just a useful but largely arbitrary label for groups of animals with similar characteristics.
You could just as easily say the same thing about race.
I'm guessing you are American, where over generations it has become a bit more cultural and less genetic. The problem is when a population is mixed and you try to label everyone as black or white. Worse, Americans label people as black even if they have only fractional black ancestry.
Clearly trying to allocate race to individuals is problematic - see the mess from affirmative action and targeted rights programs. But at the population level (group statistics) race retains powerful predictive value, even in the US. In science we know that predictive value is what makes a theory good. Newtons theory of gravity might be completely wrong in the detail of how it works, but the predictions are valid, so gravity is real, whether we understand it or not.
It's amazing to me that people can have such attachment to the concept of race when even species isn't well-defined no matter which definition you use, but there you go.
Attached how? It is a useful concept with predictive value, in medicine or public policy for example. But you get people who say things like "race does not exist" or "race is a social construct" just because a race has no clear boundaries. By that logic, species do not exist, and we are all just animals. (Unless kingdom of life is a social construct too and we are all just eukaryotes. )
The fact that we interbred with them means they were the same species as us
That might be the sort of thing they taught you in high school decades ago when we were kids, but the definition of species has had to be revised considerably since then. It is a murky concept. See Ring Species for an example of how complex it can get.
Mostly, homo sapiens and neanderthals did not interbreed, just sometimes.
I would pay top dollar for a phone wallet sewn from Mark Zuckerburg's pasty white skin.
They can grow skin in vats now. The technology was developed to grow skin for burns victims, but if you can get a small sample of Zuckerburg's skin, you could soon be growing enough for thousands of wallets that pass a DNA test.
The real harm to American working people comes from the fully lawful "guest worker" (unwelcome guest) programs.
That, but I'd say automation is the bigger issue. And changes in business practices. Big companies replacing decently-paid employees with outside contractors paying minimum wage. The gig economy. That sort of thing.
How about the complete destruction of our culture? It's happening! If you don't stop the illegals from entering. Something has to be done.
That may be a valid, if overstated, argument, but a wall is not the answer.
Walls did not keep the Mongol hordes out of China, or the Britons out of Roman England. They did not keep the zombi^Wwhite walkers out of the Seven Kingdoms, and they sure ain't going to keep illegal immigrants from the US.
There are better solutions, and first we need to deal with the dependence on low-cost undocumented labor for the agricultural sector in the US.
Simpler explanation: he disliked Trump, but really hated Hilary. (As it turns out, that applied to a lot of the US voters too.) He probably never expected Trump to win.
Maybe they could ration internet access to two hours per day, with rotating blackouts. Then people might even go out and get some exercise.
Tonga is the most obese nations on earth, making Mississippi look like it is populated by Somalis.
Life expectancy has fallen to 64 in Tonga. Tongan life expectancy used to be in the mid-70s.[8] Up to 40% of the population is said to have type 2 diabetes.[8] Tongan Royal Tufahau Tupou IV, who died in 2006, holds the Guinness World Record for being the heaviest-ever monarch - 200kg.[8]
But to the contrary, it overestimates the recidivism rate of the average black offender also by a factor of two, and expecting him to commit another crime twice as often as they actually do.
That is hard to believe, especially since the actual rate is over 50%! What the report actually said was “Blacks are almost twice as likely as whites to be labeled a higher risk but not actually re-offend,”, which is very different. Those labelled as such but not reoffending are likely a small portion of the prison population.
Still, this implies that allowing the AI system to consider race would lead to better predictions for blacks and worse for whites. So long as it has sufficient other data. It is only through poor logic and unfounded fear that data on race has been excluded from the inputs to the prediction algorithm.
Do we exclude race data from medical diagnostic algorithms because it is more likely to screen positive for heart disease in whites or bowel cancer in blacks? No, there is no unfairness, no exaggeration of risk based on race, just more accurate results. Algorithms given accurate data are not racist.
Greed, anger, peer-group status, low iq, lack of ability for delayed gratification, aggression. Perceived lack of alternative ways to gain status or wealth.
Poverty, drug addiction, lack of opportunity. Fixing that prevents crime
No, that is just wishful thinking, not evidence based. Correlation is not cause. Poverty and crime are related by common causes. There is plenty of drug addiction in the middle classes, they are just more likely to use legal drugs or not steal to buy them. Prescription narcotics kill more people than street heroin.
America's high prison rate is not just a "race issue".
The UK has an incarceration rate 7 times higher for blacks than whites. Australia has an incarceration rate 10 to 15 times higher for aboriginals than others (around 4% of adult males, similar to US blacks).
The US has a relatively low ratio of black:other imprisonment rate, 4 to 1, and there is no evidence of systemic racism in this number.
The real problem is the very high rate for the entire population!

a probe that can travel at an appreciable percentage of the speed of light? Laws of physics suggests "no".
We could send a probe at hundreds of time the speed of Oumuamua, using 1960's level nuclear propulsion. Getting it to still work in a few hundred years when it passes a nearby star system, and send a message back to earth, would be more of a challenge.

There is probably nothing wrong with the academic publication, or the field of research.
It is the "University of Toronto" press release masquerading as a news article that is nonsense.

Interbreeding as we know today happened in Europe.
It happened where they coexisted. Duh!

Please don't stoop to the level of feigned offense. It's unbecoming, and doesn't help the problem.
Irony! I'm mocking the people who get offended at everything, especially gender-related. Surely it wasn't that subtle?

(Which is not to say that poor young black males do not suffer disproportionately.)

Sending people to jail for crimes they didn't commit is a dick move
Sad how casual misandry counts as humour now. I have a dick, and I'm proud of it.
I am the entertainer
I come to do my show
You've heard my latest record
It's been on the radio
Ah, it took me years to write it
They were the best years of my life
It was a beautiful song
But it ran too long
If you're gonna have a hit
You gotta make it fit
So they cut it down to 3:05

No, Jony Ive was the designer. Jobs was the manager and salesman.
Apple was far more evil in the 80's than now. Far worse vendor lock-in, proprietary ports, poor interoperability.
Especially evil when they sued Microsoft and HP over basic element of the user interface that they had taken from Xerox.
